"Dia Bras recently acquired a silver district in Chihuahua State, 40 km from the Malpaso mill. The properties acquired cover more than 7,500 hectares, including 12 former mines that historically produced high-grade silver. This region is very promising and the potential of these former mines at depth has never been explored.
The acquisitions includes around 70 mining lots that were acquired through different transactions with Mexican families, one Mexican private company, one Canadian public company and also by claiming open ground.
The property covers the silver district of Cusi, in the central western part of the State of Chihuahua, approximately 125 km west of the city of Chihuahua. The property covers 75 square kilometers in the Sierra Madre.
Silver mineralization occurs in vertical quartz-veined breccia zones of epithermal origin, and silver and base metal sulphides enrichment are found at depth.
At least nine mineralized structures of vein/stockwork and breccia types, each ranging from 500 m to 2,000 m in length and from place to place, up to 50 m in width, were exploited by previous operators.
These structures were mined historically starting about 300 years ago but have been left untouched since the 1930s. At least 10 million ounces of silver were extracted by the Cusi Mining Company alone, between 1927 and 1932 from its five small underground mines. Few mines were exploited into the sulphide zones due to lack of infrastructure, technology and expertise."

Ich hoffe, diejenigen, die mich kennen,
wissen etwas damit anzufangen.
Die Kombination ist hier jedenfalls optimal:
- Cash durch die Basemetals.
- Brandneue Silberprop.
- Top Grades.
- Gewaltige Größe.

Was das Ganze so unfassbar gut macht?
Selbst im Stockhouse diskutiert man noch immer fröhlich über den Zinkpreis - und die möglichen Auswirkungen auf die Aktie.

I spoke with IR today at DIB. During my trip to Chihuahua this month I drove past the Malpaso Mill, and then several hours later, I drove past the Bolivar Mine. This was a concern to me, since I passed several DIB trucks loaded with ore, crawling along the narrow and winding dirt road. It would take about 10 hours each way for a fully loaded dump truck to drop a load of ore off at the mill, and I would guess that each truck could hold about 15 tonnes. So to be running at 300 tpd, you are talking in the range of 20 trucks running around the clock. That amounts to a huge expense for gas, maintenance and wear and tear, and for the fleet of trucks itself, which are owned by the company. IR confirmed that the trucking costs are the biggest expense on the bottom line, but they are still making money on the pilot mining project.
I would think that it makes a great deal of sense to get a mill located closer to the mine, sooner than later. Since they are mining high grade skarn mineralization, how much additional cash flow could be generated once they take the trucking costs out of the equation? This is very likely going to be a large project that could support a medium size mill for many years.
IR also confirmed that a small scale mining operation is underway at the second project in Chihuahua, the Cusi Mine. The company has outlined some high grade resources from the project and they are shipping some of the mineralized material to the Malpaso Mill for test mining. The capacity of the mill has been upgraded to about 850 tpd, and they built in a separate recovery circuit to handle the Cusi ore.
I have been a shareholder of DIB for a while now, and doubled my entry price. I have not taken any profits yet, and I want to see some guidance from the company to outline their plans to define a larger resource at both projects, and to build a mill closer to Bolivar. There is no question in my mind that both projects will be economic to mine at a profit if they have a shorter transportation route to the mill. So I think it is worth hanging around for a long term gain with this company.
cheers!

hihuahua during the colonial days.
The oldest mining production record in the Cusihuiriachic district goes back to the year 1687, when 500,000 tons of ore were mined and from which 1.5 tons of gold and 1,510 tons of silver were produced. The veins that were mined are the ones of the "Santa Maria" Group (San Antonio, Sta. Marina, San Bartolo, Santa Rosa y San Pedro) and "San Miguel". The "San Antonio" was the most important vein, developed by three shafts down to 150 m. At that time, thirteen (13) mills were in operation in the area. From 1881 to 1910, foreign investment was encouraged by the growth of the railway network linking Chihuahua City to Cuauhtémoc City.
The main companies that worked during those years were:
Don Enrique Mining Co. (1881-1896), exploited the "Santa Maria" mine where the "Sta Marina" and "San Bartolo" shafts were deepened to the 800-level (244 m) and installed a chlorine plant that was destroyed by fire in 1892.
Helena Mining Co. (1896-1911) bought the mines of "Santa Maria" and "San Miguel" and deepened the shafts of "Santa Maria" and "San Bartolo" to the 1000-level (305 m) and the San Miguel shaft to the 250-level (76m). The company used a chlorine plant that burned in 1902. Daily production was 60 tons of direct shipping ore obtained by manual selection grading 1,981 g/t Ag as well as 40 tons of second class ore treated at the local flotation plant and producing 4 tons of concentrate grading 3113 g/t Ag, with recovery of less than 50%. Between April 1900 and January 1903, they mined 16,416.4 tons of ore at 1347.08 g/t Ag, 18.62% Pb and 12.98% Zn. The total production for this period amounted to 150,000 tons of ore with recovery of 0.2 tons of gold and 150 tons of silver. During the years 1911 to 1937, the production was even more intense, favored by: 1) installation in 1908 of the "Avalos" smelting , whereby the process of flotation was used; 2) a branch of the district railroad extended; and, 3) the discovery the bonanza ore at the "Promontorio" mine.
Cusi Mexicana Mining Co. (established in 1911) bought the "Santa Maria" and "San Miguel" mines, which were worked until 1923. The "Santa Marina" shaft was deepened to 366m to exploit sulfide ore grading more than 600 g/t Ag from the Sta Marina, San Antonio, San Miguel and San Nicolás veins. They also mined oxide ore at San Miguel. A flotation plant was installed with a capacity of 450 t/d, which was later increased to 600 t/d. The crash of 1929 caused silver prices to drop and the operations stopped in 1937. The company subsequently moved to Maguarichi where they discovered high grade gold ore. The total production during this period is estimated at approximately 710,000 tons of ore with recovered values of 0.3 tons of gold, 330 tons of silver, 18,000 tons of lead, 5,500 tons of zinc and 700 tons of copper.
The Cusi Mining Co. produced at the Promontorio mine 200 t/d of bonanza ore at grades no less than 750 g/t Ag. The concentrates from flotation assayed between 7.5 and 15 kg/t Ag, 6% Pb, 3% Cu and some Zn with 85% recovery. The mine produced 200,000 tons of ore that generated 300 tons of silver, 0.3 ton of gold, 450 tons of lead and 220 tons of copper.
Between 1938 and 1987, the San Miguel mine was mined by "gambusinos" who accessed old workings above the water table. The degree of activity followed the price of silver with long periods of inactivity. In 1970 they resumed work and during the following six years, they shipped 125,000 tons to the smelter in El Paso, Texas.

klingt wirklich alles sehr interessant, aber die Aktie ist von 0.20 bis 1,25 Can auch erst einmal gut gelaufen.
Ich meine eine Konso wäre sicherlich im Bereich des Möglichen.
Die Frage ist, wieviel sind die wirklich wert im Verhältnis zur aktuellen MK?
Und wo positioniert man sich für den Einstieg? Vielleicht sollte man die Anfangsposition mal gleich nehmen..

Ich werde sicher noch ein paar Worte zu Dia Bras sagen - Du bist natürlich eingeladen!
Ansonsten für das nächste mal vormerken.

Zur Firma: Die Preisentwicklung bezog bisher lediglich und AUSSCHLIEßLICH den Kupfer- und Zinkpreise mit ein.
Silber ist bei KEINEM auf der Rechnung.
Insofern bin ich bei diesem Wert - dank Mike - so früh hier im Board, dass selbst Kanada kaum Ahnung hat, um was es eigentlich geht.
Position aufbauen, schlage ich vor.
Hast Du dich denn schon selbstständig informiert?
Kennst Du die DURCHSCHNITTLICHEN Silbergrades?
Das ist erheblich.
Wie viele Unzen es am Ende werden (sicherlich NICHT gleich 1 Mrd.!!!!) kann Dir keiner sagen.
Aber das geologische System ist atemraubend.

Montréal, Québec, - January 22, 2007 -
Dia Bras Exploration Inc. (DIB-V) ("Dia Bras or the "Company") is pleased to announce additional high-grade silver values from its Cusi property in the State of Chihuahua, Mexico. Re-assay of drill core yielded 35.4 Kg/t Ag over 0.4 meters from La India. In addition, channel sampling in Santa Edwiges yielded 2.7Kg/t Ag over 3.62 meters. Both of these mines are owned 100% by the Company
LA INDIA
On October 3, 2006 the Company announced a drill intersection of 1.4 meters grading over 10,000 g/t Ag (>10 Kg/t) from the drilling program at La India. Over-assay data by Chemex reveals two matters of interest: 1) the Ag content of the drill intercept is 35,442 g/t Ag (35.4 Kg/t); and, 2) the lab reversed the Company’s sample numbers, and the drill intercept is 0.4 m, not 1.4 m. The sample interval is 200.4 to 200.8 meters from drill hole DC06B012.
SAN EDWIGES
The Santa Edwiges channel sample is one of 28 collected from a structure exposed in a crosscut on the first level of the mine in an area that is being developed for early bulk sampling. Material from the bulk sample will be trucked to the Company’s mill at Malpaso, a distance of 38 km, and will be processed in the mill’s new 500 tpd circuit. In total, 28 channel samples averaged 334.3 g/t Ag, 1.01% Pb and 0.30% Zn, as shown in the table below. The true width of the sampled structure is 10 meters, and the various samples were collected around the gallery.
SURFACE MAPPING
Mapping by the Company’s geologists demonstrates that the La India-San Miguel-La Bamba mines are separated from the Santa Edwiges-Santa Marina-Promontorio mines by a NW-trending fault that has uplifted the Santa Edwiges block relative to the La India block. The silver-rich precious metals portion of the Santa Edwiges block, therefore, has been eroded and the veins exposed on the surface and in the shallow mine workings are from the base metals portion of the zoned vein system. However, as shown in the table above, high silver values are commonly found associated with base metals in that portion of the system.
The Company has received a report on the mineralogy of veins in the Santa Edwiges block from its consultant Prof. Larry Meinert, the conclusions of which are consistent with the interpretation that the Santa Edwiges block, containing the Mexicana vein and the San Antonio vein, is in the upper base metal portions of the vein system. He writes:
“Veins in the Cusihuiriachic district consist of banded, crustiform, and brecciated quartz with bands, disseminations, and massive zones of sulfide-rich ore. Except for supergene oxidized and enriched ore, such as at La India, sphalerite and galena are present in all ore zones. Thus, the Cusihuiriachic district should be thought of as a high level base metal vein system that overlies or is peripheral to a buried intrusion. This intrusion may be mineralized and the presence of carbonate rocks in the sub-surface makes the presence of skarn ore likely.
The sulfide mineralogy of the Cusihuiriachic veins is relatively simple with major sphalerite and galena, with minor pyrite and locally chalcopyrite (mainly as inclusions in sphalerite). Although looked for, no discrete Ag minerals were found by petrographic, XRD, or SEM analysis. Silver assays ranged from 104-474 ppm, for hand selected high-grade samples.”
Dia Bras acquired the Cusi district only eight months ago. This district includes 12 inactive mines that have very promising potential since they have never been explored at depth. The Company is exploring multiple silver-rich vein targets, some of which are open-pitable such as La Bamba and some are base metal and skarn replacement deposits. The program of surface mapping and sampling, surface core drilling, and underground mapping and sampling is well underway. The San Miguel and Promontorio mines are being de-watered, and the lower levels are expected to be free of water in February 2007. These levels will then be cleaned and rehabilitated, surveyed and sampled to confirm the presence of mineralized blocks reported in historical mine records.
Method of analysis
The samples from La India were analyzed by ICP and AA methods by Chemex at their facilities in Vancouver, Canada. The samples from San Edwiges were analysed by AA methods at the Malpaso Mill.

Dia Bras Exploration Inc. (DIB-V) ("Dia Bras or the "Company") is pleased to announce additional high-grade silver values from its Cusi property in the State of Chihuahua, Mexico. Re-assay of drill core yielded 35.4 Kg/t Ag over 0.4 meters from La India. In addition, channel sampling in Santa Edwiges yielded 2.7Kg/t Ag over 3.62 meters. Both of these mines are owned 100% by the Company
LA INDIA
On October 3, 2006 the Company announced a drill intersection of 1.4 meters grading over 10,000 g/t Ag (>10 Kg/t) from the drilling program at La India. Over-assay data by Chemex reveals two matters of interest: 1) the Ag content of the drill intercept is 35,442 g/t Ag (35.4 Kg/t); and, 2) the lab reversed the Company’s sample numbers, and the drill intercept is 0.4 m, not 1.4 m. The sample interval is 200.4 to 200.8 meters from drill hole DC06B012.
SAN EDWIGES
The Santa Edwiges channel sample is one of 28 collected from a structure exposed in a crosscut on the first level of the mine in an area that is being developed for early bulk sampling. Material from the bulk sample will be trucked to the Company’s mill at Malpaso, a distance of 38 km, and will be processed in the mill’s new 500 tpd circuit. In total, 28 channel samples averaged 334.3 g/t Ag, 1.01% Pb and 0.30% Zn, as shown in the table below. The true width of the sampled structure is 10 meters, and the various samples were collected around the gallery.
SURFACE MAPPING
Mapping by the Company’s geologists demonstrates that the La India-San Miguel-La Bamba mines are separated from the Santa Edwiges-Santa Marina-Promontorio mines by a NW-trending fault that has uplifted the Santa Edwiges block relative to the La India block. The silver-rich precious metals portion of the Santa Edwiges block, therefore, has been eroded and the veins exposed on the surface and in the shallow mine workings are from the base metals portion of the zoned vein system. However, as shown in the table above, high silver values are commonly found associated with base metals in that portion of the system.
The Company has received a report on the mineralogy of veins in the Santa Edwiges block from its consultant Prof. Larry Meinert, the conclusions of which are consistent with the interpretation that the Santa Edwiges block, containing the Mexicana vein and the San Antonio vein, is in the upper base metal portions of the vein system. He writes:
“Veins in the Cusihuiriachic district consist of banded, crustiform, and brecciated quartz with bands, disseminations, and massive zones of sulfide-rich ore. Except for supergene oxidized and enriched ore, such as at La India, sphalerite and galena are present in all ore zones. Thus, the Cusihuiriachic district should be thought of as a high level base metal vein system that overlies or is peripheral to a buried intrusion. This intrusion may be mineralized and the presence of carbonate rocks in the sub-surface makes the presence of skarn ore likely.
The sulfide mineralogy of the Cusihuiriachic veins is relatively simple with major sphalerite and galena, with minor pyrite and locally chalcopyrite (mainly as inclusions in sphalerite). Although looked for, no discrete Ag minerals were found by petrographic, XRD, or SEM analysis. Silver assays ranged from 104-474 ppm, for hand selected high-grade samples.”
Dia Bras acquired the Cusi district only eight months ago. This district includes 12 inactive mines that have very promising potential since they have never been explored at depth. The Company is exploring multiple silver-rich vein targets, some of which are open-pitable such as La Bamba and some are base metal and skarn replacement deposits. The program of surface mapping and sampling, surface core drilling, and underground mapping and sampling is well underway. The San Miguel and Promontorio mines are being de-watered, and the lower levels are expected to be free of water in February 2007. These levels will then be cleaned and rehabilitated, surveyed and sampled to confirm the presence of mineralized blocks reported in historical mine records.

Dia Bras: First Technical Report on Cusi
Wednesday January 31, 10:52 am ET
Current exploration program includes 20,000 meters of diamond drilling for 2007
MONTREAL, QUEBEC--(CCNMatthews - Jan. 31, 2007) - - Dia Bras Exploration Inc. (TSX VENTURE
IB - News) is pleased to receive the first technical report on its Cusi silver project in Northern Mexico. The NI 43-101 report prepared by Scott Wilson Roscoe Postle Associates Inc. (Scott Wilson RPA) and dated December 22, 2006 concludes that there is good potential for economic silver-gold mineralization on the Cusi property. The Company's current drilling program of 20,000 m of diamond drilling is being conducted on the northwestern portion of the project where 12 inactive silver mines are located. The objective of the drilling is to test the down-dip and strike extensions of the silver veins in these mines as well as define sufficient mineralization so that an initial resource calculation can be done.
ADVERTISEMENT
According to Scott Wilson RPA, the Cusi project contains several former silver-copper-zinc-lead-gold producers and on-going exploration has the objective to extend known zones of silver mineralization along the strike of the structure that hosts the La Bamba open pit as well as the San Miguel mine, the La India mine and the Santa Edwiges mine. Recent drilling near the La Bamba open pit has intersected mineralized zones that are interpreted to be down-dip extensions of mineralization exposed at the open pit. The most prominent of these are:
- 113g/t Ag over 22.5 m in hole DC06B37
- 981 g/t Ag over one meter in hole DC06B30
Scott Wilson RPA is of the opinion that these zones are open along strike and warrant further drill testing. The complete Technical Report will be filed on SEDAR and posted on Dia Bras' website (www.diabras.com).

"DIA BRAS: 2006 EXPLORATION RESULTS AND 2007 EXPLORATION PROGRAM ON THE CUSI SILVER PROPERTY
Montréal, Québec, - March 1, 2007 -
Dia Bras Exploration Inc. (DIB-V) ("Dia Bras or the "Company") is pleased to report on the results of its 2006 exploration activities at the Cusi property, located in the State of Chihuahua, Mexico, as well as on its 2007 exploration program. We have made rapid progress and we anticipate discovering a major deposit.
Dia Bras acquired the Cusi Silver Project in June 2006 by consolidating a total of 72 mineral lots covering a large land package of more than 7,900 hectares and including several producing silver mines. The Company then initiated an integrated exploration program in the northwestern part of the Project consisting of geological mapping, sampling of the open cuts, drilling, dewatering of two shafts and limited bulk sampling.
2006 results
The highlight of the 2006 program was the intersection of 35.4 kg/t Ag over 0.4 meters from La India, and the channel sampling in Santa Edwiges that yielded 2.7kg/t Ag over 3.62 meters.
The geological mapping identified a large alteration system hosted by a thick felsic ignimbrite near a fault contact with a younger andesite. The two major directions of the mineralized structures are ENE and WNW.
A total of 11,700 meters of drilling was completed in the Cusi camp, of which 5,500 meters were drilled at San Miguel and La Bamba and the rest equally split between Santa Edwiges/San Nicolas and La India. The most significant drill results are presented in table 1 below. Dia Bras holds an interest of 50% and an additional 20% in the La Bamba and San Miguel properties from Pershimco (see press release, May 31, 2006). The other 10 inactive mines are 100% owned by Dia Bras.
In addition to the drilling at La Bamba, several rock composite samples were collected from the open pit in preparation for a test bulk sample and returned very encouraging results from oxide material (see press release of December 12, 2006).
M ost of the holes drilled at Santa Edwiges stopped in highly fractured zones and could not reach the intended targets. However, the underground mapping and sampling program returned significant results as announced on January 22, 2007. The cleaning and opening of the old workings at Santa Edwiges is being performed to prepare a test bulk sample of sulfide material to be treated at the Company’s newly expanded 850 tpd Malpaso mill.
The 2007 program
The objectives of the 2007 program are two-fold: define sufficient mill feed for the Company’s Malpaso Mill and discover a high-value deposit.
These tasks will be undertaken by continuing the program put in place in June 2006. The program will consist of geological mapping, definition, extension and exploration drilling as well as dewatering, rehabilitation and development of the inactive mines.
The regional scale mapping will be extended to the rest of the property, while local detail mapping and sampling of the mineralized structures and veins will be completed.
Three surface drill rigs will perform the 25,000 meters of drilling planned for 2007. A total of 11,000 meters will be drilled to test new targets identified by the geological mapping program in 2006 and 2007, including 2,000 meters to further explore La India. The remaining meters will be drilled at San Miguel-La Bamba and in the area of Santa Edwiges- San Antonio- Santa Marina (see map attached). In addition, two underground drills will test the extension of the zones found at Santa Edwiges.

Dia Bras: High Silver Values at Cusi
MONTREAL, QUEBEC--(CCNMatthews - March 21, 2007) - Dia Bras Exploration Inc. (TSX VENTUREIB) is pleased to the report results from its ongoing exploration program on the Cusi property, located in the State of Chihuahua, Mexico.
The regional geological mapping program, under the supervision of Dr. Andre Ciesielski, has revealed the presence of a number of gold-silver veins and breccias not previously reported in the northwestern part of the Cusi property. Three groups of mineralized and brecciated faults have been identified to date, over a minimum surface strike length of 9.2 km, which is in addition to the 80 km of cumulative strike length of veins previously reported.
These newly discovered gold-silver showings, often associated with base metal values, show remarkable grades within structurally and/or hydrothermally controlled breccias, of variable width and size (several centimetres to one metre), usually crosscutting the ignimbrite, and composed of quartz - kaolinite - limonite and manganese oxide. Some of the best results from grab samples include 1.97 g/t Au and 568 g/t Ag, 0.8 g/t Au and 917 g/t Ag in the San Nicolas area and 1.2 g/t Au and 2.503 kg/t Ag in the La Gloria area (see Figure 1 and Table 1). To see Figure 1 click the following link: http://www.ccnmatthews.com/docs/cusimarch21.pdf
Following reception of these assays, a channel chip sampling program of some of the accessible historic underground workings of the vertical shaft Tiro San Nicolas was initiated, and impressive results have been received, such as: 57.4 g/t Au 1.960 kg/t Ag and 2.6% Pb, 0.086 g/t Au, 1.425 kg/t Ag and 0.28% Pb (see Table 2 and Figure 2). To see Figure 2, click the following link: http://www.ccnmatthews.com/docs/tiromarch21.pdf
Because of the high gold content reported in sample DC07AC612-B, the sample has been re-assayed and returned 58.3 g/t Au.
Other prospects of the Cusi Project area, such as the historic Promontorio Mine, also show high silver values in grab samples, such as 2.2 kg/t Ag from a brecciated zone from the drift.
These results are very encouraging in light of the 25,000-metre diamond drilling program underway, and a drill rig will be mobilized early next month to this area (see press release, March 1, 2007).

MONTREAL, QUEBEC--(CCNMatthews - March 21, 2007) - Dia Bras Exploration Inc. (TSX VENTURE
IB) is pleased to the report results from its ongoing exploration program on the Cusi property, located in the State of Chihuahua, Mexico.The regional geological mapping program, under the supervision of Dr. Andre Ciesielski, has revealed the presence of a number of gold-silver veins and breccias not previously reported in the northwestern part of the Cusi property. Three groups of mineralized and brecciated faults have been identified to date, over a minimum surface strike length of 9.2 km, which is in addition to the 80 km of cumulative strike length of veins previously reported.
These newly discovered gold-silver showings, often associated with base metal values, show remarkable grades within structurally and/or hydrothermally controlled breccias, of variable width and size (several centimetres to one metre), usually crosscutting the ignimbrite, and composed of quartz - kaolinite - limonite and manganese oxide. Some of the best results from grab samples include 1.97 g/t Au and 568 g/t Ag, 0.8 g/t Au and 917 g/t Ag in the San Nicolas area and 1.2 g/t Au and 2.503 kg/t Ag in the La Gloria area (see Figure 1 and Table 1). To see Figure 1 click the following link: http://www.ccnmatthews.com/docs/cusimarch21.pdf
Following reception of these assays, a channel chip sampling program of some of the accessible historic underground workings of the vertical shaft Tiro San Nicolas was initiated, and impressive results have been received, such as: 57.4 g/t Au 1.960 kg/t Ag and 2.6% Pb, 0.086 g/t Au, 1.425 kg/t Ag and 0.28% Pb (see Table 2 and Figure 2). To see Figure 2, click the following link: http://www.ccnmatthews.com/docs/tiromarch21.pdf
Because of the high gold content reported in sample DC07AC612-B, the sample has been re-assayed and returned 58.3 g/t Au.
Other prospects of the Cusi Project area, such as the historic Promontorio Mine, also show high silver values in grab samples, such as 2.2 kg/t Ag from a brecciated zone from the drift.
These results are very encouraging in light of the 25,000-metre diamond drilling program underway, and a drill rig will be mobilized early next month to this area (see press release, March 1, 2007).

Antwort auf Beitrag Nr.: 28.433.175 von Trade0601 am 22.03.07 15:28:28Nachdem mir ein Kanadischer Börsenbriefschreiber mit namen Hommel den Kurs bei Mountain Boy in den Keller gejagt hatte, obwohl unfassbar gute News kamen, bin ich mit solchen Aussagen immer sehr vorsichtig:
- wer weiß WANN der Markt auf den Wert aufmerksam wird?
- wer weiß, wann sich Fonds einkaufen?
- wer weiß, wann die nächsten News kommen?
Das alles kann bisweilen sehr lange dauern und der Kurs bis dahin quasi ohne Grund abbröckeln.
Aber WENN der Markt aufwacht, kann es alles sehr schnell gehen.
Deshalb muss man sich Vergleichswerte ansehen: in diesem Fall MAG Silver.
Das ist der Zielwert.
Und ins Stockhouse schielen...

Sagenhafte Zahlen:
Dia Bras Exploration Inc. (DIB-V) ("Dia Bras or the "Company") is pleased to announce more high-grade drill intercepts from its underground drilling program at the Bolivar Mine in the State of Chihuahua, Mexico.
Drilling of both the Fernandez and the Rosario trends returned high-grade intercepts. Moreover, along the recently discovered Selena breccia zone, part of the Fernandez trend, an intersection yielded 21.0 m grading 3.3% Cu and 22.3% Zn. Several holes in this lens returned high grades of copper and zinc. Furthermore, four (4) holes intersected massive sulfide in the Rosario trend, where the best section returned 8 metres grading 33.8% Zn and 0.7% Cu. The Fernandez and Rosario lenses are part of the Upper Skarn Unit at Bolivar.
“These drill results support our interpretation that massive, high-grade mineralization in both the Fernandez and the Rosario trends continues along strike and to depth below our present workings,” said Dr. Thomas L. Robyn, Executive Chairman, “These new drill intercepts open a large exploration area for the discovery of more high-grade sulfide mineralization at the Bolivar Mine. The Bolivar mineralizing system was a powerful system and we have only begun to probe the fringes of it.”
UNDERGROUND DRILLING
The underground holes were drilled from the mine’s level 6. Holes DB06BM066 through 71 tested the downward extension of the Selena breccia in the Fernandez zone, which trends ESE.

ia Bras Drills 10.5 Metres of 678 g/t Ag at Cusi
MONTREAL, QUEBEC -- (MARKET WIRE) -- April 18, 2007 -- Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to announce two high-grade silver intersections from its ongoing drill programme on the Cusi property, located in the State of Chihuahua, Mexico.
Hole DC07B91, drilled to test the section under the western half of the 100% Dia Bras owned San Antonio Pit intersected a 10.5-metre section averaging 0.1 g/t Au, 678 g/t Ag, trace Cu, 0.4% Pb and 0.2% Zn, including a 3-metre section which was assayed 0.25 g/t Au, 1.9 kg/t Ag, 0.1% Cu, 0.8% Pb and 0.25% Zn.

Hole DC 07B91 tested the down dip extension of the western portion of the San Antonio Pit. The core angle is approximately 35 degrees and should result in a true thickness of the mineralized zone of about 5 metres.
In addition, hole DC07B89, drilled to test the 100% Dia Bras owned San Bartolo Vein, intersected 16.5 metres of mixed high-grade silver and broken material filling an old stope. The hole cut an impressive section of 6.6 metres of 2.6 g/t Au, 759 g/t Ag, 0.5% Cu, 2.0% Pb and 2.5% Zn. Before entering the old stope for 7 metres, the hole intersected the remnant of the unmined material on the stope wall for 0.6 metre and returned a spectacular 0.6 g/t Au, 3.8 kg/t Ag, 3.8% Cu, 18.6% Pb and 20.3% Zn. The opposite side of the open stope returned 2.9 metres averaging 207 g/t Ag with minor Cu, Pb and Zn.

It should also be noted that because of the core angle, the true thickness of the zone is deemed to be approximately 8 metres.
Hole DC07B89 entered the open stope part of the historical San Bartolo mine. It is thus reasonable to infer that most of the material mined historically in this stope was of a similar nature as the very high grade 0.6 metres section encountered. Observation of the core shows that part of the mineralization is within a brecciated, silicified and jasperised quartz vein and the remaining broken rubble is rather of a more massive sulphide nature.
These results are very encouraging in light of the ongoing 25,000-metre diamond drilling programme and more drill holes are planned in this area for the beginning of May.

Dia Bras Drills 40.5 Metres of 100 g/t Ag at the San Antonio Pit in the Cusi Silver District
MONTREAL, QUEBEC -- (MARKET WIRE) -- May 10, 2007 -- Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to announce more high grade silver intersections from its ongoing drill program on the Cusi property, located in the State of Chihuahua, Mexico which is 100% owned by the Company.
Hole DC07B91, of which partial assay results had been previously reported (see press release, April 18th, 2007) and that was drilled to test the section under the western half of the 100% Dia Bras owned San Antonio Pit, intersected a further 40.0 metre section averaging 0.1 g/t Au, 101 g/t Ag, Cu, 1.78% Pb and 2.09% Zn, including a 6.0 metre section that assayed 0.2 g/t Au, 336 g/t Ag, 0.1% Cu, 2.1% Pb and 1.3% Zn and a second 7.5 metre section that assayed 0.1 g/t Au, 119g/t Ag, 0.2% Cu, 5.1% Pb and 8.4% Zn.

Hole DC 07B91 tested the down dip extension of the western portion of the San Antonio Pit. The core angle is approximately 35 degrees and should result in a true thickness of the mineralized zone which could vary from 10 to 15 metres, because the dip of the mineralized structure as extrapolated from surface varies from vertical to 70-80 NW.
In addition, hole DC07B92, drilled about 5 metres south of the shaft to test the 100% Dia Bras owned Santa Marina Vein in its central section, intersected two zones of gold-silver mineralization. The first zone cut 3 metres of 0.3 g/t Au, 372 g/t Ag, and traces Cu, Pb and Zn. The second intersection is a mixture of broken core and mineralization possibly left in an old pillar of the mine. It contains a 3.0 metre section of 2.30 g/t Au, 150 g/t Ag, trace Cu, 0.3% Pb and 0.78% Zn. The recovery in this last section was just over 50%. The mineralized intersection stopped in an old stope, which is estimated to be 4.4 metres in core length. The next intersection of 3.0 metres intersected low grade mineralization possibly representing the hanging wall of the mineralization.

Dia Bras drills 31 metres of 4.05% Cu and 22.75% Zn at Bolivar Mine
Montréal, Québec, - June 7, 2007 -
Dia Bras Exploration Inc. (DIB-V) ("Dia Bras or the "Company") is pleased to announce more high-grade drill intercepts from its surface exploration and underground drilling program at the Bolivar Mine in the State of Chihuahua, Mexico.
Drill hole DB07B197, an extension type drill hole (see press release of March 1st, 2007) in the El Gallo area intercepted a wide zone of Cu mineralization in the Lower Skarn – magnetite-rich zone. This hole was drilled NE due to the rugged topography in the area, and intercepted an estimated true width of some 12 metres.
This drill hole adds to the resource estimate of the El Gallo area where a 20-hole, 5000 metres drill program has been ongoing since March 2007. The objective of the program is to investigate the potential continuous extent of the Lower Skarn Unit between Mina de Fierro and the El Gallo 1 area that is being explored for low grade – bulk tonnage potential.
More drilling results are expected in the near future.

DIA BRAS Drills 1.5 Metres of 8,310 g/t Ag at Cusi Within 9.0 Metres of 1,651 g/t Ag at the Promontorio Silver Mine in the Cusi District
MONTREAL, QUEBEC--(Marketwire - June 19, 2007) - Dia Bras Exploration Inc. (TSX VENTUREIB) is pleased to announce more high grade silver intersections from its ongoing drill program on the Cusi property, located in the State of Chihuahua, Mexico.
HOLE DC07B101-B
Hole DC07B101-B was drilled to test the main, SW-dipping Promontorio vein (Vein "A") and cut the vein 20 metres above Level 7(see PR of May 8, 2007) where it encountered 8.3 Kg of silver over a drill width of 1.5 metres, which represents about 1.0 metre true width. This interval is within a 9.0 metres drill width (about 6 metres true width) that averages 1.65 Kg of silver. The hole also encountered two additional zones of veining further down the hole that are interpreted to be from NE-dipping secondary veins.

Comments
These results are highly encouraging in light of the on-going 25,000-metre diamond drilling program. Up to present, close to 9000 metres of core drilling have been completed on the Cusi Project. Additional drilling will aim at continuing defining the resources potential of the major Ag (Zn-Pb) vein structures of the Promontorio, Santa Marina -San Antonio and Santa Edwiges mines, all historical producers. The high grade of silver in Hole 101-B is consistent with the historical data previously reported (May 8, 2007) that indicate significant amounts of un-mined silver mineralized rock in the Promontorio mine.

Dia Bras Drills 19 Metres of 1.39% Cu in the Lower Skarn and 3 Metres of 12.4% Zn in the Upper Skarn at El Gallo Prospect of the Bolivar Property
08:31 EDT Tuesday, July 31, 2007
MONTREAL, QUEBEC--(CCNMatthews - July 31, 2007) - Dia Bras Exploration Inc. (TSX VENTUREIB) is pleased to announce more drill intercepts in the El Gallo area from its ongoing surface exploration drilling program at the Bolivar property in the State of Chihuahua, Mexico. These intercepts have identified a new, extensive area of potentially mineable mineralization, which is open down dip and may be significantly larger than presently inferred.
El Gallo is situated some 500 to 800 metres south-southeast of the Bolivar mine where Dia Bras is conducting its pilot-mining program. From late 2003 to the end of 2006, some 2974m in 13 diamond core holes have been drilled at El Gallo. Following a thorough review in early 2007 of the relations between the Upper Skarn and Lower Skarn mineralized trends, it was decided that a 5000m diamond drilling program would be conducted to estimate resources in both skarn units.
In El Gallo, the Upper Skarn mineralization appears to be more continuous along strike than in the Bolivar mine area. A possible explanation is that the mineralization at El Gallo is of a "manto" type rather than being a pipe or breccia.
Better mineralization (higher grades, with thicker and more continuous mineralization) in the Upper Skarn appears to be associated with an intricate relationship between the contact of the granodioritic pluton and the overlying sedimentary skarn sequence Underground mapping, drilling and pilot-mining at the Bolivar mine demonstrates that an apophysis of granodiorite ramps up and over the skarn unit and is physically associated with better mineralization. This relationship has been most notably observed at the Breccia Linda, Titanic and Selena zones of the Bolivar mine, all of particularly good grade and tonnage.
This same relationship has been recognized at El Gallo, where Dia Bras has drilled an area of 150m x 400m on a 50m x 150m drill pattern. The Company intends to extend this pattern to the north and northeast to follow El Gallo mineralization down dip. Since March 2007, 8 drill holes totaling 1 874 metres have been drilled with excellent results. More drilling is planned to extend this initial 5000m program with the objective of preparing the first resource evaluation of the El Gallo area.
This contact relationship is now a major planning factor in the Company's exploration program. It is also important to note that this relationship between a granodioritic apophysis and better mineralization is also inferred to exist at several places along the 3 km trend of exposed skarn mineralization, most notably to the southeast at La Montura, La Pequeña, La Narizona and El Val.
All drill holes reported in this news release are from the area of section 9325N (50 metres composite) which is situated in the core of El Gallo area. Here the mineralization observed in the Upper Skarn unit consists of finely disseminated to semi-massive bands of Cu-Zn mineralization over variable widths.
Drill hole DB07B198 was drilled at azimuth 248o and a dip of -77o. It intersected numerous bands of disseminated Cu-Zn mineralization, with best assays of 2.2% Cu over 4.0 metres in the Upper Skarn. In the Lower Skarn, 3 zones of disseminated sulphide mineralization were observed, with two wider zones of 7 and 8 metres of greater than 1% Cu. These widths are essentially true widths because of the angle of intercept of the drill hole with the skarns.
Drill hole DB07B199 was drilled at an azimuth of 77o and a dip of -83o. It intersected 3 metres of 10.4% Zn in the Upper Skarn and an impressive 19m of 1.4% Cu in the Lower Skarn. True widths are estimated at 2.5m and 16m, respectively.
Drill hole DB07B201, drilled vertically, intersected both the Upper and Lower Skarn mineralized zones. Assays are pending.
Drill hole DB07B202, drilled at an azimuth of 225o and a dip of -68o intersected high grade Zn mineralization, 3.3m at 6.9% Zn and 3m at 12.4 % Zn, in the Upper Skarn and a 12.5 metres section of 1.3% Cu in the Lower Skarn. These widths are essentially true widths.
Drill Hole DB07B205 was started last week and will be completed within the next week. Assay results will follow.

In El Gallo, the Upper Skarn mineralization appears to be more continuous along strike than in the Bolivar mine area. A possible explanation is that the mineralization at El Gallo is of a "manto" type rather than being a pipe or breccia.
Better mineralization (higher grades, with thicker and more continuous mineralization) in the Upper Skarn appears to be associated with an intricate relationship between the contact of the granodioritic pluton and the overlying sedimentary skarn sequence Underground mapping, drilling and pilot-mining at the Bolivar mine demonstrates that an apophysis of granodiorite ramps up and over the skarn unit and is physically associated with better mineralization. This relationship has been most notably observed at the Breccia Linda, Titanic and Selena zones of the Bolivar mine, all of particularly good grade and tonnage.
This same relationship has been recognized at El Gallo, where Dia Bras has drilled an area of 150m x 400m on a 50m x 150m drill pattern. The Company intends to extend this pattern to the north and northeast to follow El Gallo mineralization down dip. Since March 2007, 8 drill holes totaling 1 874 metres have been drilled with excellent results. More drilling is planned to extend this initial 5000m program with the objective of preparing the first resource evaluation of the El Gallo area.
This contact relationship is now a major planning factor in the Company's exploration program. It is also important to note that this relationship between a granodioritic apophysis and better mineralization is also inferred to exist at several places along the 3 km trend of exposed skarn mineralization, most notably to the southeast at La Montura, La Pequeña, La Narizona and El Val.
All drill holes reported in this news release are from the area of section 9325N (50 metres composite) which is situated in the core of El Gallo area. Here the mineralization observed in the Upper Skarn unit consists of finely disseminated to semi-massive bands of Cu-Zn mineralization over variable widths.
Drill hole DB07B198 was drilled at azimuth 248o and a dip of -77o. It intersected numerous bands of disseminated Cu-Zn mineralization, with best assays of 2.2% Cu over 4.0 metres in the Upper Skarn. In the Lower Skarn, 3 zones of disseminated sulphide mineralization were observed, with two wider zones of 7 and 8 metres of greater than 1% Cu. These widths are essentially true widths because of the angle of intercept of the drill hole with the skarns.
Drill hole DB07B199 was drilled at an azimuth of 77o and a dip of -83o. It intersected 3 metres of 10.4% Zn in the Upper Skarn and an impressive 19m of 1.4% Cu in the Lower Skarn. True widths are estimated at 2.5m and 16m, respectively.
Drill hole DB07B201, drilled vertically, intersected both the Upper and Lower Skarn mineralized zones. Assays are pending.
Drill hole DB07B202, drilled at an azimuth of 225o and a dip of -68o intersected high grade Zn mineralization, 3.3m at 6.9% Zn and 3m at 12.4 % Zn, in the Upper Skarn and a 12.5 metres section of 1.3% Cu in the Lower Skarn. These widths are essentially true widths.
Drill Hole DB07B205 was started last week and will be completed within the next week. Assay results will follow.

Dia Bras' Bolivar Pilot-Mining Program Produces Concentrate Value of US$4.8 Million in the Second Quarter
08:30 EDT Tuesday, August 14, 2007
MONTREAL, QUEBEC--(Marketwire - Aug. 14, 2007) - Dia Bras Exploration Inc. (TSX VENTUREIB) reports second quarter net estimated smelter production value from its Bolivar pilot-mining program of US$4.8 million for a cumulative amount of US$10.3 million for the first six months of 2007 compared with US$6.8 million and a cumulative amount of US$12.1 million for the same period in 2006.
During the quarter, the Company processed 28,240 DMT of material averaging grades of 5.27% Zn and 1.13% Cu (cumulative production of 58,254 DMT for the first six months of 2007 at 6.04% Zn and 1.24% Cu). In 2006, the Company had processed 22,584 DMT at grades of 11.17% Zn and 2.19% Cu (cumulative production of 45,045 DMT at grades averaging 12.39% Zn and 2.34% Cu for the first six months of 2006).
Processing of Bolivar material was mostly done at the new Triunfo circuit, where a recovery rate of 87.77% for zinc and 78.17% for copper was achieved during the period (91.87% for zinc and 80.60% for copper in 2006 at the Malpaso circuit). Decreases in recovery rates are due to a combination of lower-grade material being processed and operation of the new Triunfo circuit which remains in fine-tuning mode.
Overall, 2,255 DMT of zinc concentrate and 875 DMT of copper concentrate were produced during the quarter (cumulative production of 5,242 DMT and 2,047 DMT of zinc and copper concentrates) compared with 4,016 DMT of zinc concentrate and 1,413 DMT of copper concentrate in 2006 (cumulative production of 8,784 DMT and 2,834 DMT of zinc and copper concentrates for the first six months of 2006).
During the quarter, direct operating cash costs amounted to US$3.6 million (US$2.4 million for the same period in 2006). The increase in costs is mainly attributable to increased tonnage of material transported from the Bolivar site and processed at the Company's Malpaso milling facilities, higher transport costs due to the inconsistent availability of railroad services, increased labour costs and costs related to the start-up of the new circuit at the Malpaso mill. The operating cash flow was used for the Company's development and exploration activities.
Development efforts to access the Selena and Titanic zones, part of the Fernandez trend, resulted in additional lower grade development material being sent to and processed at the Malpaso milling facilities. "We are now processing material from the Selena zone with a marked increase in mill feed grade" says Dr. Thomas Robyn, the Company's Executive Chairman.

The pilot-mining program provides essential data on costs, logistics, grade, recovery and metallurgy that will serve for a feasibility study on the Bolivar property. The objective of the program is to generate sufficient cash flow from zinc and copper concentrate production to help finance development and exploration at the Bolivar mine and elsewhere on the Bolivar project.
It is important to note that Bolivar is not at a commercial production stage. The completion of a feasibility study is required to confirm the economic viability of a property before it is brought into commercial production. The Company expects to complete its exploration program on the Bolivar property and extensions in order to start a feasibility study in 2007.
The Company also reports that, due to exploration focus being placed on the Bolivar and Cusi properties and to the refractory metallurgy of mineralization, the Company has decided to abandon the Promontorio project, located in the region of Ocampo, in the State of Chihuahua, where limited work was performed during the past year.

Dia Bras Receives NI 43-101 Resources Evaluation on the Bolivar Cu-Zn Project
16:27 EDT Tuesday, September 25, 2007
MONTREAL, QUEBEC--(Marketwire - Sept. 25, 2007) - Dia Bras Exploration (TSX VENTUREIB) is pleased to announce Mineral Resources for the Bolivar deposit. The Company has received a Resource Evaluation for the Bolivar Cu-Zn Project, dated September 22, 2007; it was conducted by Yann Camus, P.Ing.Geo., from Geostat International, independent Qualified Person under NI 43-101 standards.
"We are pleased with the results of this resource evaluation, which provide the basis for us to initiate our pre-feasibility study for a mill on site at Bolivar" said Dr. Thomas Robyn, Executive Chairman. "With a mill on site, we will have a significant reduction of our production costs, thereby lowering the cutoff grades used in the evaluation with a resultant increase in tonnage."
The Mineral Resources of the Bolivar deposit are contained within two mineralized stratabound zones, the Upper and the Lower Skarn, which display two types of Cu-Zn mineralization: 1) a typical high grade Cu-Zn "manto"-pipe-breccia mineralization (Upper Skarn); and, 2) lower grade Cu-magnetite replacement mineralization (Lower Skarn).
All these resources are contained predominantly within two major mineralized areas, the Bolivar Alta Ley deposit and the El Gallo deposit situated some 500 metres to the south.
The Bolivar Alta Ley includes the Bolivar mine that hosts the 110 degrees Fernandez trend, in which the high grade Selena and Titanic lenses are situated, and the 310 degrees Rosario trend, in which the Breccia Linda, Rosario, Rodolpho, La Foto and San Angel lenses are found (refer to included long section at http://www.ccnmatthews.com/docs/SketchLongSection.jpg).
Geostat has estimated the Mineral Resources of the Bolivar deposit using the database up to July 31st 2007, which includes 306 diamond surface and underground drill holes for a total of 68,218 metres of drilling, which Dia Bras has provided to Geostat and which were loaded in Geostat software. A total of some 10,243 metres of assayed core were used (9,758 samples) for the resources calculation. Drilling is ongoing and resources will be upgraded as new results are made available.
In the El Gallo area, only limited drilling (approx. 8,000 m) has been performed up to present, and the Upper Skarn mineralization appears more subdued and structurally controlled as in the Bolivar mine. However, the Lower Skarn mineralization is very well defined and extends over the entire area.
Resource Evaluation
The Mineral Resources estimate for the Bolivar deposit used a cut-off grade based on average prices for copper, zinc, silver and gold, production costs and expected recovery in the resource model. Geostat has used an over-all recovery of 80% for copper and 90% for zinc. This is based on the two years of production record (February 2005 to July 2007) at the Malpaso mill. Geostat has used the production costs as determined by Dia Bras for underground mining at Bolivar. These costs are reported to be similar to other copper-zinc operations of similar scale in Mexico. At prices of US$2.00/lb. Cu, US$1.00/lb. Zn, US$10.00/oz Ag, US$500/oz Au, the cut-off grade for the Bolivar Upper Skarn deposit resource estimate is calculated as 2.5% Cu Equivalent (% Cueq). Geostat recommends that this cut-off grade be used to report Mineral Resources of the Upper Skarn for processing of rock at the Malpaso mill. The cut-off grade for the Bolivar Lower Skarn deposit resource estimate is variable at this stage, because the Lower Skarn will not be mined until a mill is constructed on site.
The Mineral Resources on the Bolivar Deposit are summarized in the following table:

Since mining and processing began in 2005, the Company has processed over 190,000 tonnes of mineralized rock from the Upper Skarn (US) at its Malpaso mill. Table 1 shows that the total measured and indicated resource of the Upper Skarn, based on work to date, is about 320,000 tonnes and the inferred resource is about 275,000 tonnes. Provided that the inferred resource is confirmed, at the current capacity of the Malpaso-Mill, this would provide five years of feed for the mill while additional resources may be discovered and developed.
In addition to the resources of the Upper Skarn, inferred resources have been calculated for the Lower Skarn in the El Gallo area. Table 2 shows the inferred tonnage at various %Cu-eq cut-off grades:

It is important to note that the Lower Skarn has only been drilled within an area that encompasses less than 5% of the known extent of the Lower Skarn horizon. Considerable drilling remains to be done to test the horizon, and the Company continues to use the Yerington, Nevada, iron-copper skarns as its exploration model, for example the Northwest deposit of 3.0 mt @ 3.45% Cu and "minor" Fe, the East deposit of 7.1 mt @ 3.36% Cu and 27% Fe, the 2 deposit of 2.0 mt @ 3.60% Cu and 28% Fe, and the Pumpkin Hollow (core) of 29.0 mt @ 1.20% Cu and 40 % Fe. The mineralized zone within the resources of the Lower Skarn shown above is open laterally, and drilling directed at extending the known mineralized zone will continue.
Table 3 shows the combined inferred resource for the Upper and Lower Skarns at various %Cu-eq cut-off grades. Note that the left-most column shows the cut-off grade for the Lower Skarn on the left side and for the Upper Skarn on the right side of the column.
Note that this table shows only inferred resources, and does not include the Measured & Indicated Resources for the Upper Skarn shown in Table 1.

Exploration Potential
On-going exploration by Dia Bras continues to extend known zones of copper, zinc, silver and gold mineralization along strike of the Rosario Trend as well as the Fernandez Trend, near the Bolivar Mine, as well as in other areas of the property, which encompass some 75 km2. Of particular interest are the newly defined targets of the La Montura - El Val trend that were recently drilled and have identified Upper and Lower Skarn type mineralization over a strike length of some 2 km, 2.5 km SW of the main Alta Ley mine area.
In the El Val area, drill hole DB07B209 intersected 2.0 metres at an average grade of 7.7% Zn in a Upper Skarn type environment within a broader mineralized intersection from 89 to 123 metres core length. Hole DB07B215, drilled some 500 metres to the NW in the Narizona area, also intersected a Cu-Zn mineralized zone, from 43 to 75 metres core length (assays pending) that shows Upper Skarn-type mineralization, and a second mineralized horizon, from 145 to 149 metres core length, with Lower Skarn type mineralization (assays pending). This corridor extends up to the La Montura showing where a drill hole done by Dia Bras in 2004 intersected 3 metres at 1.2% Cu, 5.4% Zn, 1 g/t Au and 147 g/t Ag in Upper Skarn type environment.
Geostat International is presently preparing a preliminary economic assessment in order to assess the economic potential of the Bolivar deposit. The complete preliminary economical assessment will be available under Dia Bras Exploration on the SEDAR website at www.sedar.com and on Dia Bras' website at www.diabras.com within 45 days of the present.
Dia Bras has already initiated systematic exploration drilling and has four surface and two underground drill rigs, testing all the mineralized structures continuously. Drill results will be issued as they become available.
Dia Bras Receives NI 43-101 Resources Evaluation on the Bolivar Cu-Zn Project
16:27 EDT Tuesday, September 25, 2007
MONTREAL, QUEBEC--(Marketwire - Sept. 25, 2007) - Dia Bras Exploration (TSX VENTURE
IB) is pleased to announce Mineral Resources for the Bolivar deposit. The Company has received a Resource Evaluation for the Bolivar Cu-Zn Project, dated September 22, 2007; it was conducted by Yann Camus, P.Ing.Geo., from Geostat International, independent Qualified Person under NI 43-101 standards."We are pleased with the results of this resource evaluation, which provide the basis for us to initiate our pre-feasibility study for a mill on site at Bolivar" said Dr. Thomas Robyn, Executive Chairman. "With a mill on site, we will have a significant reduction of our production costs, thereby lowering the cutoff grades used in the evaluation with a resultant increase in tonnage."
The Mineral Resources of the Bolivar deposit are contained within two mineralized stratabound zones, the Upper and the Lower Skarn, which display two types of Cu-Zn mineralization: 1) a typical high grade Cu-Zn "manto"-pipe-breccia mineralization (Upper Skarn); and, 2) lower grade Cu-magnetite replacement mineralization (Lower Skarn).
All these resources are contained predominantly within two major mineralized areas, the Bolivar Alta Ley deposit and the El Gallo deposit situated some 500 metres to the south.
The Bolivar Alta Ley includes the Bolivar mine that hosts the 110 degrees Fernandez trend, in which the high grade Selena and Titanic lenses are situated, and the 310 degrees Rosario trend, in which the Breccia Linda, Rosario, Rodolpho, La Foto and San Angel lenses are found (refer to included long section at http://www.ccnmatthews.com/docs/SketchLongSection.jpg).
Geostat has estimated the Mineral Resources of the Bolivar deposit using the database up to July 31st 2007, which includes 306 diamond surface and underground drill holes for a total of 68,218 metres of drilling, which Dia Bras has provided to Geostat and which were loaded in Geostat software. A total of some 10,243 metres of assayed core were used (9,758 samples) for the resources calculation. Drilling is ongoing and resources will be upgraded as new results are made available.
In the El Gallo area, only limited drilling (approx. 8,000 m) has been performed up to present, and the Upper Skarn mineralization appears more subdued and structurally controlled as in the Bolivar mine. However, the Lower Skarn mineralization is very well defined and extends over the entire area.
Resource Evaluation
The Mineral Resources estimate for the Bolivar deposit used a cut-off grade based on average prices for copper, zinc, silver and gold, production costs and expected recovery in the resource model. Geostat has used an over-all recovery of 80% for copper and 90% for zinc. This is based on the two years of production record (February 2005 to July 2007) at the Malpaso mill. Geostat has used the production costs as determined by Dia Bras for underground mining at Bolivar. These costs are reported to be similar to other copper-zinc operations of similar scale in Mexico. At prices of US$2.00/lb. Cu, US$1.00/lb. Zn, US$10.00/oz Ag, US$500/oz Au, the cut-off grade for the Bolivar Upper Skarn deposit resource estimate is calculated as 2.5% Cu Equivalent (% Cueq). Geostat recommends that this cut-off grade be used to report Mineral Resources of the Upper Skarn for processing of rock at the Malpaso mill. The cut-off grade for the Bolivar Lower Skarn deposit resource estimate is variable at this stage, because the Lower Skarn will not be mined until a mill is constructed on site.
The Mineral Resources on the Bolivar Deposit are summarized in the following table:

Since mining and processing began in 2005, the Company has processed over 190,000 tonnes of mineralized rock from the Upper Skarn (US) at its Malpaso mill. Table 1 shows that the total measured and indicated resource of the Upper Skarn, based on work to date, is about 320,000 tonnes and the inferred resource is about 275,000 tonnes. Provided that the inferred resource is confirmed, at the current capacity of the Malpaso-Mill, this would provide five years of feed for the mill while additional resources may be discovered and developed.
In addition to the resources of the Upper Skarn, inferred resources have been calculated for the Lower Skarn in the El Gallo area. Table 2 shows the inferred tonnage at various %Cu-eq cut-off grades:

Exploration Potential
On-going exploration by Dia Bras continues to extend known zones of copper, zinc, silver and gold mineralization along strike of the Rosario Trend as well as the Fernandez Trend, near the Bolivar Mine, as well as in other areas of the property, which encompass some 75 km2. Of particular interest are the newly defined targets of the La Montura - El Val trend that were recently drilled and have identified Upper and Lower Skarn type mineralization over a strike length of some 2 km, 2.5 km SW of the main Alta Ley mine area.
In the El Val area, drill hole DB07B209 intersected 2.0 metres at an average grade of 7.7% Zn in a Upper Skarn type environment within a broader mineralized intersection from 89 to 123 metres core length. Hole DB07B215, drilled some 500 metres to the NW in the Narizona area, also intersected a Cu-Zn mineralized zone, from 43 to 75 metres core length (assays pending) that shows Upper Skarn-type mineralization, and a second mineralized horizon, from 145 to 149 metres core length, with Lower Skarn type mineralization (assays pending). This corridor extends up to the La Montura showing where a drill hole done by Dia Bras in 2004 intersected 3 metres at 1.2% Cu, 5.4% Zn, 1 g/t Au and 147 g/t Ag in Upper Skarn type environment.

Dia Bras Exploration Inc./New Discovery at Bolivar: 32.5 Metres of 4.26% Zn at La Narizona Prospect
10/18/2007
MONTREAL, QUEBEC, Oct 18, 2007 (Marketwire via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTUREIB) is pleased to announce very encouraging drill intercepts in the La Narizona area from its ongoing surface exploration drilling program at the Bolivar property in the State of Chihuahua, Mexico.
New Discovery
At La Narizona, hole DB07B215 intersected the Upper Skarn from 42.7 to 75.2 metres (32.5 metres drill width), and another skarn zone from 144.5 to 148.8 metres. The Upper Skarn intersections average 4.26% Zn, 0.31% Cu, 21.61 g/t Ag and 0.01 g/t Au over an extraordinary 32.5 metres. Within this wide intersection, two higher grade sections occur, including a 7.9 m section averaging 13.14% Zn, 0.78% Cu, and 55.98 g/t Ag. This 7.9 metre section also contains silver and lead, averaging 55.98 g/t Ag and 0.29 % Pb, with a 0.7 metre sample (48.6 - 49.3 metre core length) assaying 24.4% Zn, 1.29% Cu, 324 g/t Ag and 2% Pb.
The second mineralized intersection in skarn occurs at the level expected of the Lower Skarn, but is significantly different in that it contains very little magnetite and is rich in zinc but poor in copper, averaging some 6.76% Zn, 0.17% Cu and 2.78 g/t Ag over 4.3 m, including a richer 2.1 metre section of 10.65% Zn, 0.28% Cu, 3.7 g/t Ag and 2% Pb.
This mineralization occurs within the sedimentary section between two faults, and mapping and drill data indicate it may have significant dip and strike extent and could represent significant new resources for the Bolivar project (see press release of September 25, 2007).
\\\"This is a very exciting development for our exploration program\\\", says Francois Auclair, Vice-President of Exploration. \\\"The volume potential for this mineralization is major, and the mineralized corridor is very significant as it demonstrates that the high-grade mineralization present at Bolivar Alta Ley where Dia Bras is conducting its pilot-mining activities extends over a much broader area than previously known. An expanded drilling program is planned in 2008.\\\"

The La Narizona prospect is located within the La Montura - El Val corridor, an area some 2.5 km to the SE of the Alta Ley Bolivar mine. The La Narizona area is situated some 500 metres NW of El Val, in an area of exoskarn that is enclosed within andesite in a highly fractured and faulted block. This block represents the hanging wall of the mineralization that has been uplifted with respect to the footwall andesite. In some publications, this corridor is referred to as the Sauzal-Cieneguita lineament (Goodell P., 2003, internal communication to Dia Bras).
At both ends of this corridor, mineralization was previously intersected by drilling, namely in the La Montura area where a drill hole performed by Dia Bras in 2004 intersected 3 metres at 1.2% Cu, 5.4% Zn, 1 g/t Au and 147 g/t Ag in the Upper Skarn and, more recently, in the El Val area, where hole DB07B209 intersected 6.6 metres of 2.6% Zn in the Upper Skarn, and an additional 2.0 metres at an average grade of 7.7% Zn (reported in press release, September 30, 2007) in the Upper Skarn within a broader mineralized intersection from 89 to 123 metres down hole (34 metres drill width).
Detailed mapping done by Dia Bras in the fall of 2006 revealed Upper Skarn mineralization in the historical La Pequena, La Narizona and El Val prospects (see press release of December 14, 2006), and prompted the Company to initiate a drilling program in this area in the spring of 2007. A number of logistical problems, including an unusually strong rainy season, delayed drilling until recently.
Dia Bras\\\' drilling program at El Val-La Narizona is ongoing with one surface high capacity drill rig in operation. As of September 30th, approximately 2,075 metres in 5 drill holes have been completed. Hole DB07B216 is in progress, while results from hole DB07B212 are pending. Hole DB07B194, which was interrupted by technical problems in April, will be completed soon.
Method of analysis
Samples were prepared at ALS Chemex lab facility in Chihuahua, Mexico, and analyzed by ICP and AA methods by ALS Chemex at their facilities in Vancouver, Canada.
Quality control
Diamond drill samples sent for analysis consist of half NQ-size diamond core split on site, prepared by ALS Chemex sample preparation laboratory in Chihuahua, Mexico, and assayed for Au by 50 g fire assay with AA finish and for Ag by AA on 50 g split sample at the ALS Chemex North Vancouver Laboratory. Assays for Pb, Zn and Cu are done by Induction Coupled Plasma (ICP) at ALS Chemex. The quality assurance-quality control (QA-QC) of Dia Bras has been described in detail in both RPA\\\'s 43-101 reports of December 2006 at Cusi and October 2005 for Bolivar.
The technical content of this news release has been approved by Francois Auclair, P. Geo. and Vice-President, Exploration of Dia Bras, a Qualified Person as defined in NI43-101.

At both ends of this corridor, mineralization was previously intersected by drilling, namely in the La Montura area where a drill hole performed by Dia Bras in 2004 intersected 3 metres at 1.2% Cu, 5.4% Zn, 1 g/t Au and 147 g/t Ag in the Upper Skarn and, more recently, in the El Val area, where hole DB07B209 intersected 6.6 metres of 2.6% Zn in the Upper Skarn, and an additional 2.0 metres at an average grade of 7.7% Zn (reported in press release, September 30, 2007) in the Upper Skarn within a broader mineralized intersection from 89 to 123 metres down hole (34 metres drill width).
Detailed mapping done by Dia Bras in the fall of 2006 revealed Upper Skarn mineralization in the historical La Pequena, La Narizona and El Val prospects (see press release of December 14, 2006), and prompted the Company to initiate a drilling program in this area in the spring of 2007. A number of logistical problems, including an unusually strong rainy season, delayed drilling until recently.
Dia Bras\\\' drilling program at El Val-La Narizona is ongoing with one surface high capacity drill rig in operation. As of September 30th, approximately 2,075 metres in 5 drill holes have been completed. Hole DB07B216 is in progress, while results from hole DB07B212 are pending. Hole DB07B194, which was interrupted by technical problems in April, will be completed soon.
Method of analysis
Samples were prepared at ALS Chemex lab facility in Chihuahua, Mexico, and analyzed by ICP and AA methods by ALS Chemex at their facilities in Vancouver, Canada.
Quality control
Diamond drill samples sent for analysis consist of half NQ-size diamond core split on site, prepared by ALS Chemex sample preparation laboratory in Chihuahua, Mexico, and assayed for Au by 50 g fire assay with AA finish and for Ag by AA on 50 g split sample at the ALS Chemex North Vancouver Laboratory. Assays for Pb, Zn and Cu are done by Induction Coupled Plasma (ICP) at ALS Chemex. The quality assurance-quality control (QA-QC) of Dia Bras has been described in detail in both RPA\\\'s 43-101 reports of December 2006 at Cusi and October 2005 for Bolivar.

Dia Bras: High Gold and Silver Values at Cusi
Montréal, Québec, - November 15, 2007 -
Dia Bras Exploration Inc.is pleased to report results from its ongoing exploration program on the Cusi property, located in the State of Chihuahua, Mexico.
The regional geological mapping program, under the supervision of Dr. André Ciesielski, has revealed the presence of a number of gold-silver veins and breccias not previously reported in the northwestern and central part of the Cusi property. Dia Bras reported in March (see Press Release #8, March 21) and in September (see Press Release #24, September 13) unusually high gold assays from an area known as the San Nicolas Tiro.
A review of these data prompted Dia Bras to start a detailed mapping program in the area under the supervision of Dr. Ciesielski. The mineralization is hosted in a number of N-S structures, of variable width, the most important of which is the La Minerva system.
This area is characterized by three brecciated structures, known as:
Minerva, quartz stockwork-breccia, limonite-psylomelane breccia, and quartz veins,
N310 fault, unmineralised limonite-kaolinite breccia,
Gloria, silicified breccia and quartz veinlets-stockwork.
The Minerva structure strikes N350 and dips 75o and presents variable widths of 0.5 to 2.0 m. The fractures are filled with quartz, and limonite -- psylomelane breccia (0.5 to 1.5 m), with quartz stockwork-breccia (0.1 to 1 m), and can be observed at the contact with the wall rock. This structure has been followed for over 200 m. A NE-SW regional fracturation is present everywhere in the Minerva area, and influences the breccia, especially in the south.
The southern extremity of the Minerva structure (N-S) intersects or deviates at another major system known as the Gloria structure (NE-SW).
The northern extremity of the Minerva structure (N-S) intersects a N310 fault (NE-SW). At this point, the structure separates into two fracture systems, a quartz stockwork, the Minerva A, some 50 cm wide, oriented at N165 with a 70o dip, with a strike extent of some 120 m long. The Minerva B consists of a major quartz stockwork, with widths varying from 1 to 4 metres, oriented at N190 with a 70o dip, which extends for some 100 metres.
Samples are either channel or representative chip and grab samples from mineralized zones. All samples were taken on surface from the mineralized structures.
Some of the best results include 1.46 g/t Au with 3,490 g/t Ag, 4.6 g/t Au with 1,530 g/t Ag, 2.49 g/t Au with 794 g/t Ag, 5.51 g/t Au with 719 g/t Ag. The high gold and silver contents are accompanied by low contents of Pb, Zn and Cu, which indicates that this vein system is high in the precious metal zone. This is very encouraging with respect to the amount of mineralized rock that could occur in these structures and others like them in the immediate vicinity.
This area has received limited exploration in the past, and has never been drilled.
These results are very encouraging and a drill program planned for the beginning of 2008 is being prepared to follow up on these excellent results.

Dia Bras Announces High-Grade Silver Values at the Promontorio and Santa Edwiges Mines of the Cusi Project
MONTREAL, QUEBEC--(Marketwire - Jan. 30, 2008) - Dia Bras Exploration Inc. (TSX VENTUREIB) is pleased to report results from its ongoing exploration drilling program on the Cusi property, located in the State of Chihuahua, Mexico.
PROMONTORIO SECTOR:
The silver-rich Promontorio sector continues to deliver high-grade silver intersections over economic widths and they are particularly encouraging. The best results from the last batch of drill assays of the year come from hole DC07B151 which intersected a number of high-grade veins. The best interval averaged 528 g/t Ag, 0.1 g/t Au, 0.1% Cu, 0.2% Pb and 0.2% Zn over 15 metres core length. This length does not represent the true width, since the drill hole was drilled directly along the dip of the veins, which vary in thickness from 10 to 25 cm. The estimated true width is 2.6 metres. Also, this hole intersected Veta A, which averages 704 g/t Ag, 0.1 g/t Au, 0.2% Cu, 1.2% Pb and 1.0% Zn over 5.3 metres of core length (estimated true width of 3.7 metres).

Another important hole in this sector is DC07B132, results of which were partly released in December 2007. The hole intersected a series of veins (see press release December 13, 2007). The hole intersected 6 metres core length (estimated true width of 4.2 metres) of 141 g/t Ag, 0.19 g/t Au, 0.5% Pb and 0.4% Zn. Mineralization at Promontorio is associated with fracture-filled, low-sulphidation veins with high precious-metals grades, typical of a high level epithermal system. The most prominent vein in the sector is Veta A, and Dia Bras has reported high historical grades as well as the Company's drill core data from this vein and from its intersections with crosscutting subsidiary veins (see press release June 7, 2007).
SANTA EDWIGES - SAN ANTONIO -- SAN MARINA SECTOR
The best results in this sector are from hole DC07B139, drilled to test the downdip extension of the San Marina mineralized structure, which intersected 3.5 metres core length (true width of 2.5 metres) of 0.4 g/t Au, 269 g/t Ag, 0.1% Cu, 3.7% Pb and 5.3% Zn.
DC07B143, drilled to test the Santa Edwiges structure, intersected 2.8 metres core length (true width of 2.0 metres) of 2.1 g/t Au, 187 g/t Ag, 1.1% Pb and 0.6% Zn.
The Santa Edwiges -- San Antonio -- San Marina sector consists of multiple fracture-filled quartz-carbonate veins containing high sulphide contents that are typical of the middle portion (Pb-Zn-Cu) of a zoned, low-sulphidation epithermal vein. This middle portion of the vein transitions upwards to the precious metal (Au, Ag) portion of the vein.

2007 DRILL PROGRAM
Since inception of the drilling program in the Cusi District in March 2007, more than 21,800 metres of diamond drilling have been completed to date, in addition to more than 10,000 metres drilled in 2006. Surface mapping (see press release of November 15, 2007) and surface diamond core drilling (see press release of September 13, 2007) have demonstrated the importance of the Promontorio and Santa Edwiges - San Antonio - San Marina sectors subsequent to a resource evaluation.

Dia Bras Announces High-Grade Silver Values at the Promontorio and Santa Edwiges Mines of the Cusi Project
MONTREAL, QUEBEC--(Marketwire - Jan. 30, 2008) - Dia Bras Exploration Inc. (TSX VENTURE
IB) is pleased to report results from its ongoing exploration drilling program on the Cusi property, located in the State of Chihuahua, Mexico.PROMONTORIO SECTOR:
The silver-rich Promontorio sector continues to deliver high-grade silver intersections over economic widths and they are particularly encouraging. The best results from the last batch of drill assays of the year come from hole DC07B151 which intersected a number of high-grade veins. The best interval averaged 528 g/t Ag, 0.1 g/t Au, 0.1% Cu, 0.2% Pb and 0.2% Zn over 15 metres core length. This length does not represent the true width, since the drill hole was drilled directly along the dip of the veins, which vary in thickness from 10 to 25 cm. The estimated true width is 2.6 metres. Also, this hole intersected Veta A, which averages 704 g/t Ag, 0.1 g/t Au, 0.2% Cu, 1.2% Pb and 1.0% Zn over 5.3 metres of core length (estimated true width of 3.7 metres).

2008-02-06 09:41 ET - News Release
Mr. Daniel Tellechea reports
DIA BRAS REPORTS HIGHLIGHTS OF ITS 2007 EXPLORATION AND DEVELOPMENT PROGRAM AND PRESENTS ITS 2008 OBJECTIVES
Dia Bras Exploration Inc. has provided a summary of its 2007 exploration and development program, the Bolivar pilot-mining results, and presented its 2008 objectives.
2007 highlights:
* Appointment of Daniel Tellechea as president and chief executive officer and restructuring of the company;
* Discovery of a new massive sulphide lens in the upper skarn, the Selena, with grades of up to 2.2 per cent copper and 13.1 per cent zinc at Bolivar mine with a drill hole intersection of up to 43 metres (DB07BM070);
* New discovery at Bolivar -- 32.5 metres of 4.26 per cent zinc in drill hole DB07B215 at La Narizona prospect;
* Widest lower skarn intersection in the El Gallo area -- 73.8 metres of core length (69.4-metre estimated true width) averaging 1.2 per cent Cu, 41 grams per tonne silver and 0.1 g/t gold;
* Preliminary economic study indicates strong IRR and NPV at Bolivar with the construction of a mill on site;
* Numerous high-grade silver intercepts at Promontorio and Santa Edwiges, including 8,310 g/t Ag over 1.5 metres (core length) at Promontorio (hole DC07B101B) and four-metre core length (true width of 2.8 metres) of 2.6 g/t Au, 502 g/t Ag, 1.4 per cent lead and 0.8 per cent Zn in hole DC07B133, in the San Antonio mineralized structure, within the Cusi district;
* Regional mapping reveals the presence of a number of high-grade gold and silver targets in the northwestern portion of the Cusi property;
* Production value of $26.8-million (U.S.) from the pilot-mining program at Bolivar including a record production value of $8.4-million (U.S.) in the fourth quarter of 2007.
Summary Bolivar -- 2007
Exploration
In September, 2007, Dia Bras released a National Instrument 43-101 resource estimate, which established that the upper skarn unit contains about 322,400 tonnes at 5.16-per-cent copper equivalent in the measured and indicated categories, and the lower skarn unit contains from 936,000 tonnes at 1.99-per-cent CuEq (1.5-per-cent CuEq cut-off) up to 3,248,000 Mt at 1.34-per-cent CuEq (0.75-per-cent CuEq cut-off).
The 2007 exploration program has opened up some significant new exploration opportunities with considerable upside potential.
Over 25,000 metres of drilling were completed, mainly at the Bolivar Alta Ley and El Gallo sectors and the El Val-La Montura sectors resulting in the announced discoveries, compared with 11,100 metres of drilling in 2006.
Pilot-mining program
During the year, at Bolivar, Dia Bras processed about 127,000 tonnes of material at an average grade of 1.52 per cent Cu and 7.07 per cent Zn for a total net smelter production value of $26.8-million (U.S.).
Summary Cusi -- 2007
Exploration
More than 21,800 metres of diamond drilling were completed, which reveal the presence of economic intersections, thus demonstrating the importance of the northwestern sector. For 2006, 11,700 metres of drilling were performed, of which 5,500 metres were drilled at San Miguel-La Bamba and the rest equally split between Santa Edwiges/San Nicolas and La India.
During 2007, Dia Bras rehabilitated and provided access to mineralized structures in two underground mines, Santa Edwiges and Promontorio, while continuing to drill in an attempt to start a first resource evaluation by the end of the first quarter of 2008.
Development
The 20,000 tonnes of material from the various accessible mineralized zones at Cusi were processed at the Malpaso mill, but recovery was too low to provide the commercial production of concentrates, especially from the oxide and transition zones (mixed oxide and sulphide zones). Metallurgical testing will continue during 2008 for the sulphide zones.

(1) It is important to note that Bolivar is not at a commercial production
stage. The completion of a feasibility study is required to confirm the
economic viability of a property before it is brought into commercial
production. The company expects to complete sufficient exploration work on
the Bolivar property and extensions in order to start a feasibility study
in 2008.
(2) Non-GAAP (generally accepted accounting principles) measures. The company
reports net smelter production value and operating cash costs even if they
are non-GAAP measures to indicate the approximate value of the year sales,
isolate the measure of pilot-mining, operation-cost activities less amortization
and depreciation. The company believes this is useful supplemental information.
However, it should not be considered as a substitute for measure of performance
prepared in accordance with GAAP.
(3) Before amortization.
Dia Bras objectives 2008:
* Cost improvement program in all areas of the of the company;
* Aggressive exploration program to expand and upgrade existing resources at Bolivar to increase mine life and level of production;
* Continue exploration at Cusi to establish first resource estimate and evaluate start-up of pilot mining;
* Initiate a feasibility study at Bolivar to obtain parameters for eventual full-scale production, including construction of an appropriate-sized mill on site;
* Process 144,000 tonnes of material at average grades of 1.4 per cent Cu and 8 per cent Zn for a total net smelter production value of $24-million (U.S.);
* Blue sky exploration outside Bolivar and Cusi mining areas.
Mr. Tellechea, president and chief executive officer, comments: "We have the resources and the team in place to deliver on our aggressive but achievable objectives for both projects during 2008. We have designed our exploration and work programs so that both properties will be systematically advanced. We look forward to reporting on the results of these drill programs and our overall progress throughout 2008."
The company begins 2008 with a cash position of approximately $6.7-million (U.S.) to support its continuing programs.
2008 exploration budget
A global exploration budget of $5-million (U.S.) is forecast in 2008 to accelerate the feasibility study at Bolivar and to obtain a National Instrument 43-101 resource estimate of the Santa Edwiges and Promontorio sectors, and test newly mapped discovered zones within the Cusi project.
Bolivar project
Bolivar -- Alta Ley
Drilling will be focused on increasing the measured and indicated resources at the Bolivar Alta Ley, especially within the Titanic and Selena massive sulphide lenses, and along the Fernandez trend. Ten thousand metres of core diamond drilling (surface and underground) are planned in this area.
Bolivar -- El Gallo
A further 5,000 metres of drilling are planned in this area to: (1) allow upgrading some of the inferred resource of the El Gallo lower skarn to measured and indicated; and (2) further increase the total tonnage of the upper and lower skarn horizons of this prospect.
Bolivar -- exploration drilling
An exploration drilling program of 5,000 metres will allow the company to demonstrate the bulk volume potential of the Bolivar property. This drilling will be dedicated to evaluate the strike extension of the favourable upper and lower skarn horizons over 2,000 metres of strike length along the El Val-La Montura trend where 32.5 metres averaging 4.26 per cent Zn have been intersected at La Narizona prospect.
Cusi project
Activities will be focused on metallurgical testing with the objective of improving metal recovery, especially for the material from the transition zones (mixed oxides and sulphides) and sulphide zones to a commercial level to allow start-up of the pilot-mining program.
About 15,000 metres of drilling are planned at Cusi to further define the resources at Santa Edwiges and Promontorio, as well as evaluate by drilling the potential of the Minerva area discovered during the surface mapping program. The company intends to drill about 2,000 metres in this area to evaluate the potential of this sector. A first NI 43-101 resource estimate will be initiated and results are expected during April of this year.
Further, Dia Bras plans to initiate a surface mapping and sampling at program at the La Reina prospect, situated in the southeastern area of the Cusi property. This area has seen limited work in the past. This area of interest is considered to hold some of the highest silver grades of the Cusi camp.
Restructuring of management
As part of the restructuring, Dr. Thomas L. Robyn now assumes the position of non-executive chairman.
Also, Andre St-Michel has resigned as executive vice-president and chief operating officer for personal reasons, effective Feb. 1, 2008. Mr. St-Michel will remain as director of the company. The board of directors expresses its appreciation to Mr. St-Michel for his contribution to the company and wishes him well in his future business endeavours.

TSX VENTURE: DIB
Apr 08, 2008 07:30 ETDia Bras Intersects High-Grade Copper-Gold at the Bolivar Property
MONTREAL, QUEBEC--(Marketwire - April 8, 2008) - Dia Bras Exploration Inc. (TSX VENTUREIB) is pleased to announce the richest Upper Skarn intersection in the El Gallo area and provide an update on the 2008 exploration program at its Bolivar Project as well as new drilling results.
In the El Gallo area, hole DB08B240 intersected 7.5 metres of 4.53% Cu, 3.75 g/t Au and 383 g/t Ag, including a 4-metre section averaging 6.1% Cu, 6.78 g/t Au and 644 g/t Ag that represents the highest precious metal content intersected to date in the Upper Skarn of El Gallo.
"Hole 240 contains the richest drill intersection in the El Gallo area," says Dr. Thomas L. Robyn, chairman of Dia Bras. "This drill hole is situated some 75 metres SE of hole DB07B225 that intersected the widest Lower Skarn horizon and indicated potential thickening and enrichment of the Lower Skarn horizon towards the SE. These results are particularly exciting because this new zone of high-grade mineralization in the Upper Skarn is located 500 metres SE of our active pilot-mining area where we are mining high grades of zinc and copper. Our success at La Narizona, which is another 1,500 metres SE of El Gallo, raises the exploration potential of this trend. The area of prospective ground is being increased with each drill hole."

To view: Section of drill holes DB08B240 and DB08B242, please visit the following link: http://media3.marketwire.com/docs/Section_hole.pdf
Further, hole DB08B242 (a 25-metre offset of hole 240) intersected a high grade copper intersection in the Upper Skarn averaging 3.1% Cu, 0.38 g/t Au and 57 g/t Ag over 18 metres core length (15.6 metres true width), including a 9.0 metre section core length (7.8 metres true width) that averages 4.46% Cu, 0.60 g/t Au and 75 g/t Ag.
Results from these holes indicate to the Company's geologists that drilling is approaching an important mineralized area because both the Upper and Lower Skarns show an increase in grade and thickness. Moreover, the appearance of abundant bornite (click here to view the photo of the drill core 240: http://media3.marketwire.com/docs/photo_Hole.pdf) as well as low zinc and elevated gold contents in the Upper Skarn indicate that this mineralization represents a higher-temperature zone in the vicinity of a significant feeder conduit for mineralizing fluids. Dia Bras is drilling on a 25 x 50 metre grid to determine the lateral extent of this high-grade copper-gold zone.
Bolivar Mine Area (Alta Ley)
Surface and underground diamond core drilling at Bolivar Alta Ley are aimed at continuing to define the Rosario and Fernandez mineralized trends while also identifying potential new zones of mineralization, as well as further delineating the Selena, Titanic and Rosario massive sulfide lenses.
Hole DB07228 intersected 7.6% Cu and 2.05% Zn over 2.30 metres core length (1.6 metres true width) in the Upper Skarn horizon of the Selena lens and a further 0.47% Cu and 4.85% Zn over 4.90 metres core length (3.5 metres true width).
Some of the best intersections from the underground drilling, which is continuing to define the high-grade Upper Skarn lenses, include holes DB07BM122 (3.35 metres of 8.38% Cu and 4.03% Zn), DB07BM132 (3.8 metres of 1.12% Cu and 11.1% Zn), DB08BM142 (13.6 metres of 2.81% Cu and 8.35% Zn), all drilled in the Selena lens, and hole DB07BM129 (1.75 metre of 3.16% Cu and 5.51% Zn) in the Titanic zone.
El Gallo Area
Drilling in the El Gallo area continues to intersect widespread disseminated and stringer copper mineralization in the magnetite-bearing Lower Skarn and high-grade zinc in the Upper Skarn.
Some of the best intersections, apart from holes DB08B240 and 242 mentioned earlier, include holes DB08B234 that intersected two zones of Lower Skarn-type mineralisation, in which a number of copper-bearing intersections were encountered, including a 21-metre section core length (16.1 metre estimated true width) averaging 2.8% Cu, 0.1% Pb, 41 g/t Ag and 0.1 g/t Au, including a 9.6-metre section that averaged 3.9% Cu and 77 g/t Ag, hole DB08B223 that intersected 8.20 metres of 1.3% Cu and 26 g/t Ag, and hole DB08B238, which intersected 3.57% Cu over 6.1 metres.
La Montura Area
The best intersection in this area was in hole DB08B235 which intersected 9.38% Zn over 16.70 metres in Upper Skarn-type mineralisation at La Narizona, including a higher grade section averaging 17.04% Zn over 6.90 metres. This new intersection indicates that La Narizona is a block of mineralisation over at least 100 X 50 X 20 metres, although it is still open to the NE and SE.
2008 Drill Program
In the first quarter of 2008, 6,172 metres of core diamond drilling have been completed at Bolivar (surface and underground).

Apr 08, 2008 07:30 ETDia Bras Intersects High-Grade Copper-Gold at the Bolivar Property
MONTREAL, QUEBEC--(Marketwire - April 8, 2008) - Dia Bras Exploration Inc. (TSX VENTURE
IB) is pleased to announce the richest Upper Skarn intersection in the El Gallo area and provide an update on the 2008 exploration program at its Bolivar Project as well as new drilling results.In the El Gallo area, hole DB08B240 intersected 7.5 metres of 4.53% Cu, 3.75 g/t Au and 383 g/t Ag, including a 4-metre section averaging 6.1% Cu, 6.78 g/t Au and 644 g/t Ag that represents the highest precious metal content intersected to date in the Upper Skarn of El Gallo.
"Hole 240 contains the richest drill intersection in the El Gallo area," says Dr. Thomas L. Robyn, chairman of Dia Bras. "This drill hole is situated some 75 metres SE of hole DB07B225 that intersected the widest Lower Skarn horizon and indicated potential thickening and enrichment of the Lower Skarn horizon towards the SE. These results are particularly exciting because this new zone of high-grade mineralization in the Upper Skarn is located 500 metres SE of our active pilot-mining area where we are mining high grades of zinc and copper. Our success at La Narizona, which is another 1,500 metres SE of El Gallo, raises the exploration potential of this trend. The area of prospective ground is being increased with each drill hole."
To view: Recent Drill Hole Location of El Gallo Area, please visit the following link: http://media3.marketwire.com/docs/ElGallo_hole.pdf
To view: Section of drill holes DB08B240 and DB08B242, please visit the following link: http://media3.marketwire.com/docs/Section_hole.pdf
Further, hole DB08B242 (a 25-metre offset of hole 240) intersected a high grade copper intersection in the Upper Skarn averaging 3.1% Cu, 0.38 g/t Au and 57 g/t Ag over 18 metres core length (15.6 metres true width), including a 9.0 metre section core length (7.8 metres true width) that averages 4.46% Cu, 0.60 g/t Au and 75 g/t Ag.
Results from these holes indicate to the Company's geologists that drilling is approaching an important mineralized area because both the Upper and Lower Skarns show an increase in grade and thickness. Moreover, the appearance of abundant bornite (click here to view the photo of the drill core 240: http://media3.marketwire.com/docs/photo_Hole.pdf) as well as low zinc and elevated gold contents in the Upper Skarn indicate that this mineralization represents a higher-temperature zone in the vicinity of a significant feeder conduit for mineralizing fluids. Dia Bras is drilling on a 25 x 50 metre grid to determine the lateral extent of this high-grade copper-gold zone.
Bolivar Mine Area (Alta Ley)
Surface and underground diamond core drilling at Bolivar Alta Ley are aimed at continuing to define the Rosario and Fernandez mineralized trends while also identifying potential new zones of mineralization, as well as further delineating the Selena, Titanic and Rosario massive sulfide lenses.
Hole DB07228 intersected 7.6% Cu and 2.05% Zn over 2.30 metres core length (1.6 metres true width) in the Upper Skarn horizon of the Selena lens and a further 0.47% Cu and 4.85% Zn over 4.90 metres core length (3.5 metres true width).
Some of the best intersections from the underground drilling, which is continuing to define the high-grade Upper Skarn lenses, include holes DB07BM122 (3.35 metres of 8.38% Cu and 4.03% Zn), DB07BM132 (3.8 metres of 1.12% Cu and 11.1% Zn), DB08BM142 (13.6 metres of 2.81% Cu and 8.35% Zn), all drilled in the Selena lens, and hole DB07BM129 (1.75 metre of 3.16% Cu and 5.51% Zn) in the Titanic zone.
El Gallo Area
Drilling in the El Gallo area continues to intersect widespread disseminated and stringer copper mineralization in the magnetite-bearing Lower Skarn and high-grade zinc in the Upper Skarn.
Some of the best intersections, apart from holes DB08B240 and 242 mentioned earlier, include holes DB08B234 that intersected two zones of Lower Skarn-type mineralisation, in which a number of copper-bearing intersections were encountered, including a 21-metre section core length (16.1 metre estimated true width) averaging 2.8% Cu, 0.1% Pb, 41 g/t Ag and 0.1 g/t Au, including a 9.6-metre section that averaged 3.9% Cu and 77 g/t Ag, hole DB08B223 that intersected 8.20 metres of 1.3% Cu and 26 g/t Ag, and hole DB08B238, which intersected 3.57% Cu over 6.1 metres.
La Montura Area
The best intersection in this area was in hole DB08B235 which intersected 9.38% Zn over 16.70 metres in Upper Skarn-type mineralisation at La Narizona, including a higher grade section averaging 17.04% Zn over 6.90 metres. This new intersection indicates that La Narizona is a block of mineralisation over at least 100 X 50 X 20 metres, although it is still open to the NE and SE.

Gute Frage.
Wenn ich mir die Umsätze - in Kanada natürlich ! - der von mir beobachteten bzw. sich im Portfolio befindlichen Explorer anschaue, ist da alles sehr mau.
Abgesehen von den ring-of-fire area plays.
An Explorer will momentan keiner ran. Ganz einfache Risikoaversion.

Dia Bras and Pershimco Sign Letter of Binding Intent to Joint Venture the San Miguel and La Bamba Properties in The Cusi Silver Mining Camp, Mexico
MONTREAL, QUEBEC--(Marketwire - May 6, 2008) - Dia Bras Exploration Inc. (TSX VENTUREIB) is pleased to announce that the Dia Bras and its Mexican affiliate Dia Bras Mexicana has signed a Binding Letter of Intent (the "LOI") setting the terms of a 50-50 Joint Venture Agreement (the "JV") with Pershimco Resources Inc. (TSX-V: Pro) and its affiliate Minero Metalurgica San Miguel ("Dia Bras") for Pershimco's La Bamba and San Miguel Properties (the "Properties") located in the Cusi Silver Mining District in the State of Chihuahua, Mexico.
Dia Bras earned its 50% interest in the Properties by investing US$1.5 million in the Phase 1 of the exploration and development programs. As part of the JV terms, both Pershimco and Dia Bras will inject a sum of US$1.25 million each to finance the Phase 2 drilling to define a silver mineral resource at the Properties. Dia Bras has already completed US$500,000 in the Phase 2 work program. A final agreement containing all necessary administrative and legal Mexican compliances is being completed and both parties are expected to sign shortly.
All future exploration and development of the Properties will be managed under a Mexican subsidiary ("MEXCO") operated by Pershimco. The MEXCO Board of Directors will consist of representatives from both Pershimco and Dia Bras, and will be chaired by Pershimco for the first two years. Dia Bras will have an option to earn an additional 20% in MEXCO and the Properties, by notifying Pershimco of its intent to exercise this option, and by completing a Phase 3 work program with a minimum work expenditure of US $1.75 million. Pershimco will have a similar right, assuming Dia Bras does not exercise the 20% additional interest option within 45 days after completing the Phase 2 work program.
Daniel Tellechea, President and CEO states " The JV and proposed expenditure commitments for the Properties are significant milestones for Dia Bras and its shareholders. Work by Dia Bras on the JV Properties has demonstrated that the La Bamba and San Miguel mines can be re-opened quickly once further work brings the excellent silver mineralization within these mines to a 43-101 compliant status of Measured and Indicated categories. This will add to the silver resource that the Company has defined at its Promontorio and Santa Edwiges mines, further adding to the resource base of Dia Bras."
The La Bamba and San Miguel Properties
Mineralized host rocks are highly oxidized, revealing the black centimetric silver veins and stockworks, in places accompanied by quartz, sphalerite (zinc sulphide) and galena (lead sulphide). Individual veins trend in several directions, including N-S, NE-SW, NW-SE and sub-horizontal. They are generally 10 cm to 1 m wide and contain silver grades between 100 g/t to more than 1,000 g/t in the narrower intervals. Veins outline several rectangular or lozenge-shaped and metric-sized blocks, composed of highly fractured and brecciated hosts that plunge very steeply to the SW. Silver grades inside these blocks tend to be less than 100 g/t. The pattern was observed across a minimum 35 m true width based on the underground workings at La Bamba. The pattern may have horizontal and vertical extents in the tens of meters. Additional surface and underground work, including drilling, should reveal their full extent, litho-structural relationships, and potential higher-narrow and lower-bulk grade potential.
Drill hole results to date confirm that narrower intervals contain higher silver grades, generally approaching the 1 kg/t, and can exceed 3 kg/t, and when wider envelopes are included, silver grades generally remain over 100 g/t, up to 40 m intervals. Both Pershimco and Dia Bras believe that there is a significant silver system that could contain a potential higher grade / lower volume and lower grade and larger volume silver mineralization using combined narrow higher grade silver veins and wider lower grade silver haloes.
Dia Bras and Pershimco are poised to initiate a 20,000 m drill program at La Bamba and San Miguel, where both parties expect outlining the full silver potential within the next year.

Dia Bras Announces High Grade Silver and Gold Drill Intercepts From its Drilling Program at its Cusi Project
MONTREAL, QUEBEC--(Marketwire - June 4, 2008) - Dia Bras Exploration Inc. (TSX VENTUREIB) is pleased to report on its on-going drilling program at the Cusi silver district. Individual assays from the holes are shown in the tables at the end of this release.
The objectives of the on-going drilling program at Cusi are to upgrade the resources in the Santa Edwiges and Promontorio sectors, as well as targeting individual structural corridors identified during the mapping program of 2007.
To support the resource evaluation and to complement the surface drilling program, Dia Bras initiated an underground drilling program similar to the Bolivar ongoing underground program. This program has the objective to follow up mineralized zones exposed at the Santa Edwiges and Promontorio structures from the surface drilling. The results of all the drilling performed until March 31, 2008 at Cusi were included in the resource calculation and can be found on Dia Bras website. Since April 2008, more than 2882 metres of surface (2142m) and underground (740m) drilling have been completed.
One hole drilled before April with spectacular results, hole DC08M23 was not included in the resource estimates of March due to the complex structural pattern.
SANTA EDWIGES - SAN ANTONIO - SAN MARINA SECTOR
The underground drilling has allowed Dia Bras to delineate high-grade ore shoots along the Santa Rosa zone and along the Santa Marina trend.
In this area, high grade silver and gold mineralization is associated with zinc and lead mineralization. The best intersection was observed in hole DC08M023, which intersected 1345 g/t Ag, 14.05 g/t Au, 1.10% Zn, 1.60% Pb and 0.1% Cu, over a core length of 1.0 metre (true width estimated at 0.85 metre). Other high grade intersections include 1235 g/t Ag, 0.34 g/t Au, 1.40% Zn, 9.20% Pb and 0.20% Cu, over 1.0 metre core length (0.75 metre true width); 400 g/t Ag, 1.3 g/t Au and only a trace of sulphides over 1.5 metre core length (1.0 metre estimated true width) in hole DC08M27; and 43 g/t Ag, 4.67 g/t Au, 0.7% Zn, 0.8% Pb and 0.1% Cu over 1.5 m core length (1.1 m true width) in hole DC08M26.
A very rich sulfide zone was also encountered in the same area in hole DC08M25, which intersected 853 g/t Ag, 0.11 g/t Au, 16.6% Zn, 25.4% Pb and 0.2% Cu over a core length of 0.9 metres (true width of 0.75 metre) and in hole DC08M29, which intersected 130 g/t Ag, 0.37 g/t Au, 6.70% Zn, 11.8% Pb and 0.1% Cu over a core length of 3.0 metres (2.73 metres true width).
As previously reported, the Santa Edwiges -- San Antonio -- San Marina sector consists of multiple fracture-filled quartz-carbonate veins containing high sulphide contents that are typical of the middle portion (Pb-Zn) of a zoned, low-sulphidation epithermal vein. This middle portion of the vein transitions upwards to the precious metal (Au, Ag) portion of the vein.
Surface drilling resulted in the Promontorio sector reveals 503 g/t Ag, 0.1 g/t Au, with a trace of sulphide over a core length of 1.5 metres (estimated true width of 0.8 metre).

Dia Bras Announces High Grade Silver and Gold Drill Intercepts From its Drilling Program at its Cusi Project
MONTREAL, QUEBEC--(Marketwire - June 4, 2008) - Dia Bras Exploration Inc. (TSX VENTURE
IB) is pleased to report on its on-going drilling program at the Cusi silver district. Individual assays from the holes are shown in the tables at the end of this release.The objectives of the on-going drilling program at Cusi are to upgrade the resources in the Santa Edwiges and Promontorio sectors, as well as targeting individual structural corridors identified during the mapping program of 2007.
To support the resource evaluation and to complement the surface drilling program, Dia Bras initiated an underground drilling program similar to the Bolivar ongoing underground program. This program has the objective to follow up mineralized zones exposed at the Santa Edwiges and Promontorio structures from the surface drilling. The results of all the drilling performed until March 31, 2008 at Cusi were included in the resource calculation and can be found on Dia Bras website. Since April 2008, more than 2882 metres of surface (2142m) and underground (740m) drilling have been completed.
One hole drilled before April with spectacular results, hole DC08M23 was not included in the resource estimates of March due to the complex structural pattern.
SANTA EDWIGES - SAN ANTONIO - SAN MARINA SECTOR
The underground drilling has allowed Dia Bras to delineate high-grade ore shoots along the Santa Rosa zone and along the Santa Marina trend.
In this area, high grade silver and gold mineralization is associated with zinc and lead mineralization. The best intersection was observed in hole DC08M023, which intersected 1345 g/t Ag, 14.05 g/t Au, 1.10% Zn, 1.60% Pb and 0.1% Cu, over a core length of 1.0 metre (true width estimated at 0.85 metre). Other high grade intersections include 1235 g/t Ag, 0.34 g/t Au, 1.40% Zn, 9.20% Pb and 0.20% Cu, over 1.0 metre core length (0.75 metre true width); 400 g/t Ag, 1.3 g/t Au and only a trace of sulphides over 1.5 metre core length (1.0 metre estimated true width) in hole DC08M27; and 43 g/t Ag, 4.67 g/t Au, 0.7% Zn, 0.8% Pb and 0.1% Cu over 1.5 m core length (1.1 m true width) in hole DC08M26.
A very rich sulfide zone was also encountered in the same area in hole DC08M25, which intersected 853 g/t Ag, 0.11 g/t Au, 16.6% Zn, 25.4% Pb and 0.2% Cu over a core length of 0.9 metres (true width of 0.75 metre) and in hole DC08M29, which intersected 130 g/t Ag, 0.37 g/t Au, 6.70% Zn, 11.8% Pb and 0.1% Cu over a core length of 3.0 metres (2.73 metres true width).
As previously reported, the Santa Edwiges -- San Antonio -- San Marina sector consists of multiple fracture-filled quartz-carbonate veins containing high sulphide contents that are typical of the middle portion (Pb-Zn) of a zoned, low-sulphidation epithermal vein. This middle portion of the vein transitions upwards to the precious metal (Au, Ag) portion of the vein.
Surface drilling resulted in the Promontorio sector reveals 503 g/t Ag, 0.1 g/t Au, with a trace of sulphide over a core length of 1.5 metres (estimated true width of 0.8 metre).

Auszug aus den First Quarter Results (Quelle: Dia Bras Homepage):
First Quarter 2008 Highlights
Sales of approximately $6.6 million at Bolivar Mine property from pilot mining, a 16% increase compared with $5.7 million in the corresponding period of 2007;
Operating cash costs per dry metric tonne of US$95.56 (see Non-GAAP measured (1) (2) (3)), representing 21% decrease from US$121.97 for the same period last year;
6,172 metres of drilling at Bolivar and 6,476 in Cusi, for a combined total of 12,645 metres of drilling was completed during the quarter, on target to reach 40,000 – 45,000 metres of drilling in 2008. This ongoing program is focusing on expanding and upgrading current resources at Bolivar and increasing the first resources at Cusi.
Option to acquire 100% of the La Engañosa property in the Jalisco State of Mexico, which has an historical resource (non-NI43-101 compliant) of 1 million tonnes at an average grade of 1.2% Cu and 51 g/t Ag – with potential to hold a copper-silver ore body amenable to easy open pit mining;
Resources
Dia Bras announced an updated resource at Bolivar: total of 945,400 tonnes at 2.72% CuEq in the Measured and Indicated categories and more than 4.0 Mt at 1.84% CuEq in the Inferred category, all at a 2.5% CuEq cut-off for the upper skarn and 1% CuEq cut-off for the lower skarn (see press release March 3, 2008). We continue extensive drilling on the property and on-going results are very encouraging. The Company is confident the 2008 exploration program will further increase the size of resource in advance of a feasibility study in late 2008 or early 2009.
In April, the Company received its first NI43-101 compliant Mineral Resource for Santa Edwiges and Promontorio sectors of the Cusi silver district: 2.12 million oz AgEq in the Measured and Indicated categories and 14.6 million oz AgEq in the Inferred category (see press release May 1, 2008). The 15,000 metres on-going program is directed at increasing the first resource of the Santa Edwiges and Promontorio structures as well as defining new mineralized structures previously untested.
During the quarter ended March 31, 2008, the Company realized a net income of $780,010 ($0.01 per share) compared with a net loss of $1,423,231 ($0.01 per share) in 2007.

TSX VENTURE: DIB
Jun 18, 2008 09:26 ETDia Bras Signed a JV Agreement for the San Miguel and La Bamba Silver Properties
MONTREAL, QUEBEC--(Marketwire - June 18, 2008) - Dia Bras Exploration Inc. (TSX VENTUREIB) (the Company) reports that the Company signed a joint venture agreement with Pershimco Resources Inc. (TSX VENTURE:PRO) (the "JV") for the San Miguel and La Bamba Properties (the "Properties") which cover 36-hectare located in the Cusi Silver Mining District in the State of Chihuahua, Mexico. Pershimco and Dia Bras each hold a 50% interest in the Properties.
Pursuant to the terms of the JV, Pershimco must incur US$1.5 million of expenditures on the Properties before having the right to acquire an additional 20% of the Properties at a cost of US$1.0 million. The JV provides for Pershimco being the operator for all exploration and development of the Properties which will be managed by a jointly-owned Mexican subsidiary named DiaPro Mexicana ("DIAPRO").
A 10,000 metre drilling program will start soon under the direction of Pershimco. The program will test the depth extension of the silver mineralization to a minimum 500 metre vertical depth, well below the current 150 metre vertical mine workings. Two drill rigs will be in operation 24 hours a day, seven days a week to complete the drill program. The objective of the drilling program is to delineate a mineral resource in compliance with National Instrument 43-101 in the coming months.
The San Miguel Property is a historical mine with five underground levels with visually confirmed silver mineralization to a minimum depth of 150 metres. The La Bamba Property is contiguous with the San Miguel Property and also hosts a historical mine with two underground levels with visually confirm silver mineralization to a minimum depth of 100 metres vertical depth as well as a historical open pit mine. Mineralization has been confirmed at surface by historical work on the Properties.
Exploration and development work completed to date suggests that a significant silver mineral resource may be present in the San Miguel/La Bamba mineralized zone situated on the Properties. This zone covers an area of 1 km by 0.5 km.
This technical content of this press release was approved by Francois Auclair, geologist and Vice President, Exploration of Dia Bras, a Qualified Person as such term is defined under National Instrument 43-101.
In May-June 2006, Dia Bras staked ground and entered into agreements to earn interest in more than 7,500 hectares of contiguous property (the Cusi Silver Mining Camp), including 12 former mines. La Bamba and San Miguel mineral lots cover 36-hectare.

Jun 18, 2008 09:26 ETDia Bras Signed a JV Agreement for the San Miguel and La Bamba Silver Properties
MONTREAL, QUEBEC--(Marketwire - June 18, 2008) - Dia Bras Exploration Inc. (TSX VENTURE
IB) (the Company) reports that the Company signed a joint venture agreement with Pershimco Resources Inc. (TSX VENTURE:PRO) (the "JV") for the San Miguel and La Bamba Properties (the "Properties") which cover 36-hectare located in the Cusi Silver Mining District in the State of Chihuahua, Mexico. Pershimco and Dia Bras each hold a 50% interest in the Properties.Pursuant to the terms of the JV, Pershimco must incur US$1.5 million of expenditures on the Properties before having the right to acquire an additional 20% of the Properties at a cost of US$1.0 million. The JV provides for Pershimco being the operator for all exploration and development of the Properties which will be managed by a jointly-owned Mexican subsidiary named DiaPro Mexicana ("DIAPRO").
A 10,000 metre drilling program will start soon under the direction of Pershimco. The program will test the depth extension of the silver mineralization to a minimum 500 metre vertical depth, well below the current 150 metre vertical mine workings. Two drill rigs will be in operation 24 hours a day, seven days a week to complete the drill program. The objective of the drilling program is to delineate a mineral resource in compliance with National Instrument 43-101 in the coming months.
The San Miguel Property is a historical mine with five underground levels with visually confirmed silver mineralization to a minimum depth of 150 metres. The La Bamba Property is contiguous with the San Miguel Property and also hosts a historical mine with two underground levels with visually confirm silver mineralization to a minimum depth of 100 metres vertical depth as well as a historical open pit mine. Mineralization has been confirmed at surface by historical work on the Properties.
Exploration and development work completed to date suggests that a significant silver mineral resource may be present in the San Miguel/La Bamba mineralized zone situated on the Properties. This zone covers an area of 1 km by 0.5 km.
This technical content of this press release was approved by Francois Auclair, geologist and Vice President, Exploration of Dia Bras, a Qualified Person as such term is defined under National Instrument 43-101.
In May-June 2006, Dia Bras staked ground and entered into agreements to earn interest in more than 7,500 hectares of contiguous property (the Cusi Silver Mining Camp), including 12 former mines. La Bamba and San Miguel mineral lots cover 36-hectare.

Dia Bras reports 8.4 metres of 4.97% Cu and 25.45% Zn from the Titanic 2 Zone, Bolivar Project
Montréal, Québec, - September 16, 2008 -Dia Bras Exploration Inc. (TSX-V: DIB) is pleased to provide new drilling results from the ongoing 20,000-metre exploration program at its Bolivar project. (Click here to view the Table Recent Assay Results).
Drilling Results
More than 2,100 metres of underground drilling were performed during the past three months, mostly in the San Angel and San Francisco Areas. Some of the most spectacular assay results were observed in the Titanic 2 Zone. Hole DB08BM166 intersected 8.4 metres (estimated true width of 5.9 metres) of 4.97% Cu, 25.45% Zn, 29.3 g/t Ag and 0.07 g/t Au, while hole DB08BM171 intersected 4.7 metres (estimated true width 1.14 metre) 5.17% Cu, 23.46% Zn, 41.4 g/t Ag and 0.11 g/t Au. More drilling will be done in this area to assess the lateral continuity of the Titanic lens towards the ENE.
At the El Gallo zone, 1,800 metres of surface drilling were completed, and best results from the ongoing surface drilling program include 9.0 metres core length (8.0 metres estimated true width) of 2.31% Cu, 1.35% Zn, 51.7 g/t Ag and 0.58 g/t Au in hole DB08B263 and 9.6 metres (7.7 metres estimated true width) of 2.4% Cu, 0.13% Zn, 36.75 g/t Ag and 0.14 g/t Au in hole DB08B269.
These results will be integrated in the new resource calculation which is being conducted by SGS Geostat that should be made available in October and will be the foundation of the Feasibility Study of the Bolivar Project.
Bolivar Mine Area (Alta Ley)
Surface and underground diamond core drilling at Bolivar Alta Ley are aimed at continuing to define the Rosario and Fernandez mineralized trends while also identifying potential new zones of mineralization, as well as further delineating the Selena, Titanic and Rosario massive sulfide lenses.
In the Bolivar Alta Ley zone, the best underground drill intercepts were observed in the newly discovered San Angel Zone (refer to news release May 28, 2008) where DB08BM177 intersected 5.4 metres core length (1.85 metres estimated true width) of 2.46% Cu, 15.33% Zn, 37.4 g/t Ag and 0.23 g/t Au, and in hole DB08BM147 that intersected 4.7 metres core length (estimated true width of 3.0 metres) of 2.5% Cu, 6.9% Zn, 44 g/t Ag and 0.06 g/t Au.
Bolivar Mine Area (San Francisco)
The San Francisco zone is a newly opened underground area. A 160-metre positive ramp from Alta Ley reached this zone at the beginning of July, and definition drilling and development work will be undertaken soon. This zone was discovered in 2004 and 2005 during the surface drilling exploration program. Underground drilling has enabled the defining of a block of mineralized material statement, which should be announced in October.
The best underground intersections in this area came from hole DB08BM170 that intersected 4.80 metres core length (estimated true width of 1.24 metres) of 0.29% Cu, 12.57% Zn, 13.8 g/t Ag and 0.04 g/t Au. Other holes of interest in this area include DB08BM170 that intersected 8.0 metres core length (2.07 metres estimated true width) of 0.4% Cu, 3.04% Zn, 8 g/t Ag and 0.14 g/t Au.
El Gallo Area
In the El Gallo area, drilling to complete the new resource calculation enabled the discovery of a number of high-grade copper – bornite zones (ref. press release of April 8, 2008). 5,800 metres of drilling have so far been completed in 2008, bringing the total drilling in this area since its inception in 2007 to 10,326 metres.
Other relevant results in this area include 8.9 metres (8.7metres estimated true width) of 1.38% Cu, 5.47% Zn, 73.5 g/t Ag and 0.4 g/t Au and a second intersection grading 2.23% Cu, a trace of Zn, 35 g/t Ag and 0.7 g/t Au over 6.0 metres (estimated true width of 5.9 metres) in hole DB08B266, which was drilled in an area between the San Francisco lens and the El Gallo zone. Consequently, this could indicate a potential continuity of the El Gallo towards the WNW, thus increasing its size significantly. More drilling is planned to determine the extent of this zone.
La Montura Area
Due to heavy rain and dangerously unstable slopes, no drilling was realised in this area during the last three months.
2008 Drill Program
Since the beginning of 2008, 18,714 metres of core diamond drilling have been completed at Bolivar (surface and underground).
Method of analysis
Samples were prepared at the Chemex lab facility in Chihuahua, Mexico, and analyzed by ICP and AA methods at their facilities in Vancouver, Canada. Diamond drill samples sent for analyses consisted of half NQ-size diamond core split on site, prepared by the ALS Chemex sample preparation laboratory in Chihuahua, Mexico, and assayed for Au by 50 g fire assay with AA finish, and for Ag by AA on 50 g split sample at the ALS Chemex North Vancouver Laboratory. Assays for Pb, Zn and Cu are done by Induction Coupled Plasma (ICP) at Chemex.
Quality control
The quality assurance-quality control (QA-QC) of Dia Bras has been described in detail in both Scott Wilson Roscoe Postle Associates 43-101 reports of December 2006 at Cusi and October 2005 for Bolivar.
The technical content of this news release has been approved by Thomas L. Robyn, Ph.D. Chairman of the Board of Dia Bras, a Qualified Person as defined in NI43-101.

Dia Bras Increases Resources at its Bolivar Cu-Zn Project and Plans New Mill on Site
09:19 EST Monday, November 10, 2008
MONTREAL, QUEBEC--(Marketwire - Nov. 10, 2008) - Dia Bras Exploration (TSX VENTUREIB) is pleased to announce that it has received an updated Resource Evaluation for the Bolivar Cu-Zn Project, effective September 25th, 2008 and dated October 31st, 2008 that was conducted by Yann Camus, P. Eng. Geo., from SGS Geostat Ltd., independent Qualified Person under NI 43-101 standards.
"The pilot mining program initiated by the Company in late 2005 has met its objectives" stated Daniel Tellechea, President and CEO of Dia Bras Exploration. "We have factual information on the metallurgy of the copper and zinc mineralization, recovery rates, per tonne revenues at various commodity prices, mining costs and other factors. We can now focus our attention on construction of a mill on site and eliminate the high transportation cost of shipping rock to our Malpaso mill, which was always considered a temporary measure to obtain this essential information. We are very excited about the positive impact a mill on site will have on the project economics."
Resource Evaluation
Effective September 25th, 2008, total undiluted resources from the Bolivar project have increased 26% to a total of 1,188,800 tonnes at 1.26 Cu%, 2.35 Zn%, 0.28g/t Au and 30.7g/t Ag in the Measured and Indicated categories and have increased 55% to 6,290,100 tonnes at 1.18% Cu, 0.99% Zn, 0.30g/t Au and 26.4g/t Ag in the Inferred Resources category, all at a 2.5% CuEq cut-off for the Upper Skarn (US) and 1% CuEq cut-off for the Lower Skarn (LS) and other zones (see tables). The preliminary economic assessment of November 2007 determined that the project could prove economic with two scenarios. This new resource is a significant increase over the last resource calculation of March 2008 effective December 31st 2007. Dia Bras believes that this significant increase is sufficient for the construction of a 500 tpd mill on site. Early-stage activities for the construction, such as securing surface land for a mill site, environmental permitting and acquisition of water rights, are in progress.
The Mineral Resources estimate for the Bolivar deposit used a cut-off grade based on average prices for copper, zinc, silver and gold, production costs and expected recovery in the resource model. The 2007 Preliminary Economic Assessment by SGS Geostat expects the mill recoveries for Cu, Zn, Au and Ag to be 90%. SGS Geostat has used the production costs as determined by Dia Bras for underground mining at Bolivar. These costs are reported to be similar to other copper-zinc operations of similar scale in Mexico. The cutoff grades are based on metal price assumptions of US$2.00/lb. Cu, US$1.00/lb. Zn, US$10.00/oz Ag and US$500/oz Au. SGS Geostat recommends that the above cut-off grade be used to report Mineral Resources of the Upper Skarn for processing of rock at the Malpaso mill. Resource estimate for the Bolivar Lower Skarn deposit can be calculated at different cut-off grades at this stage, because a block model has been built. The Lower Skarn will not be mined until a mill is constructed on site.
The Company will continue to move toward increasing Measured and Indicated Resources by conducting additional infill drilling and moving towards a 25 x 25 m hole spacing, which is required in order to calculate M&I Resources.
Resources of the Bolivar ProjectCalculated by Yann Camus, Eng., SGS Geostat Ltd.,Resources situation on the 2008-09-25Prices used for calculation are Cu: 2.00 $/lb, Zn: 1.00 $/lb, Au: 500 $/oz, Ag: 10

CIM Definitions were followed for the resource estimate. 2. A minimum width of 2 m was used for a mineralized zone. 3. Densities of mineralized rock are indicated in the tables.SGS Geostat has estimated the Mineral Resources of the Bolivar deposit using the database up to 25th of September 2008, which includes 465 diamond surface and underground drill holes for a total of 86,502.61 metres of drilling, which Dia Bras has provided to SGS Geostat and were incorporated in SGS Geostat software. A total of some 15,678.19 metres of assayed core was used (14,747 samples) for the resources calculation.
Most of the Resources of the US were calculated by cross sectional method, the remainder by inverse distance block model, while the Resources of the LS were calculated by inverse cubic power of the distance block model.
Since the last resource calculations, and notwithstanding the ongoing pilot-mining program, Measured and Indicated resources of the Upper Skarn had a slight increase of 12% in tonnage while Inferred resources have increased by 47% in tonnage. Between the two latest resource calculations, the Company has mined 99,202 tonnes of rock that has been shipped to the Malpaso mill and processed.
Exploration Potential
On-going exploration by Dia Bras continues to extend known zones of copper, zinc, silver and gold mineralization along the strikes of the Fernandez Trend and the Rosario-Rodolfo Trend, near the Bolivar Mine, as well as in other areas of the property, which encompasses some 75 km2. The San Francisco zone, for example, has significant upside potential that is only beginning to be determined.

Effective September 25th, 2008, total undiluted resources from the Bolivar project have increased 26% to a total of 1,188,800 tonnes at 1.26 Cu%, 2.35 Zn%, 0.28g/t Au and 30.7g/t Ag in the Measured and Indicated categories and have increased 55% to 6,290,100 tonnes at 1.18% Cu, 0.99% Zn, 0.30g/t Au and 26.4g/t Ag in the Inferred Resources category, all at a 2.5% CuEq cut-off for the Upper Skarn (US) and 1% CuEq cut-off for the Lower Skarn (LS) and other zones (see tables). The preliminary economic assessment of November 2007 determined that the project could prove economic with two scenarios. This new resource is a significant increase over the last resource calculation of March 2008 effective December 31st 2007. Dia Bras believes that this significant increase is sufficient for the construction of a 500 tpd mill on site. Early-stage activities for the construction, such as securing surface land for a mill site, environmental permitting and acquisition of water rights, are in progress.
The Mineral Resources estimate for the Bolivar deposit used a cut-off grade based on average prices for copper, zinc, silver and gold, production costs and expected recovery in the resource model. The 2007 Preliminary Economic Assessment by SGS Geostat expects the mill recoveries for Cu, Zn, Au and Ag to be 90%. SGS Geostat has used the production costs as determined by Dia Bras for underground mining at Bolivar. These costs are reported to be similar to other copper-zinc operations of similar scale in Mexico. The cutoff grades are based on metal price assumptions of US$2.00/lb. Cu, US$1.00/lb. Zn, US$10.00/oz Ag and US$500/oz Au. SGS Geostat recommends that the above cut-off grade be used to report Mineral Resources of the Upper Skarn for processing of rock at the Malpaso mill. Resource estimate for the Bolivar Lower Skarn deposit can be calculated at different cut-off grades at this stage, because a block model has been built. The Lower Skarn will not be mined until a mill is constructed on site.
The Company will continue to move toward increasing Measured and Indicated Resources by conducting additional infill drilling and moving towards a 25 x 25 m hole spacing, which is required in order to calculate M&I Resources.

CIM Definitions were followed for the resource estimate. 2. A minimum width of 2 m was used for a mineralized zone. 3. Densities of mineralized rock are indicated in the tables.SGS Geostat has estimated the Mineral Resources of the Bolivar deposit using the database up to 25th of September 2008, which includes 465 diamond surface and underground drill holes for a total of 86,502.61 metres of drilling, which Dia Bras has provided to SGS Geostat and were incorporated in SGS Geostat software. A total of some 15,678.19 metres of assayed core was used (14,747 samples) for the resources calculation.
Most of the Resources of the US were calculated by cross sectional method, the remainder by inverse distance block model, while the Resources of the LS were calculated by inverse cubic power of the distance block model.
Since the last resource calculations, and notwithstanding the ongoing pilot-mining program, Measured and Indicated resources of the Upper Skarn had a slight increase of 12% in tonnage while Inferred resources have increased by 47% in tonnage. Between the two latest resource calculations, the Company has mined 99,202 tonnes of rock that has been shipped to the Malpaso mill and processed.
Exploration Potential
On-going exploration by Dia Bras continues to extend known zones of copper, zinc, silver and gold mineralization along the strikes of the Fernandez Trend and the Rosario-Rodolfo Trend, near the Bolivar Mine, as well as in other areas of the property, which encompasses some 75 km2. The San Francisco zone, for example, has significant upside potential that is only beginning to be determined.

Dia Bras Reports High-Grade Assays From its Cusi Project, Chihuahua, Mexico
MONTREAL, QUEBEC, Feb 18, 2009 (MARKET WIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to announce highlights from drilling at its Cusi property during the last half of 2008. The information and tables below report only the intercepts above 300 g/t Ag. A complete report showing all holes drilled and their results is available on the Company's web page (www.diabras.com) and SEDAR.
The Company's results from 2008 demonstrate the project's high grades of silver in multiple areas and its potential for significant silver production.
In the fourth quarter of 2008, data compilation and interpretation of Dia Bras' drilling and underground work produced four new target types near Dia Bras' underground workings as well as elsewhere in the most intensely silver mineralized part of the district, which lies between the Santa Eduwiges and Promontorio mines. These targets include:
1. Surface silver oxide mineralization above known veins that crop out in the San Antonio pit.
2. The Santa Rosa "chimney" or stockwork body, a bulk tonnage, underground high-grade silver resource that consists of disseminated and veinlet controlled argentite mineralization.
3. Silver mineralization in silicified wall rock in +2 meter envelopes showing 100 to 300 g/t Ag assays around the major quartz veins.
4. New veins showing previous stoping and mining activity peripheral and perpendicular to the Santa Eduwiges and Promontorio vein systems including the Tascate, Mexicana, San Nicolas, and Minerva veins.
During 2008, 14,235 meters of core were drilled at Cusi to further define silver, gold and base metal resources along the Santa Eduviges, San Antonio, Santa Marina, Santa Rosa "stockwork", Tascate, and Minerva veins. In January, 2009 drilling at Cusi advanced an additional 586 meters from both surface and underground platforms. Several holes cut veins with more than 300 g/t Ag, as shown in the following tables.
Drill Meterage from the Second Half of 2008
Meterage shows a significant decline in output after July, 2008 as development drilling of the Santa Eduwiges vein system wound down. The Company's exploration emphasis shifted to underground exploration for new high-grade gold-silver resources to support the Cusi pilot mining.

Cusi drill results from the first and second quarters of 2008 are described in press releases dated April 10 and June 3, 2008.
Santa Rosa "Stockwork" Zone
In plan view, the Santa Rosa "stockwork" zone occupies a 50 x 150 meter area that has been drilled to a depth of 50 meters below the 2000 Level of the Santa Eduwiges mine and continues for an unknown distance to depth. Mineralization consists of a strongly fractured, pervasively silicified and quartz veined zone. Argentite is the dominant silver mineral in the Santa Rosa "stockwork" zone and is associated with both quartz veinlets and as disseminated blebs and grains within crushed and broken rhyolite host.

During 2008, 14,235 meters of core were drilled at Cusi to further define silver, gold and base metal resources along the Santa Eduviges, San Antonio, Santa Marina, Santa Rosa "stockwork", Tascate, and Minerva veins. In January, 2009 drilling at Cusi advanced an additional 586 meters from both surface and underground platforms. Several holes cut veins with more than 300 g/t Ag, as shown in the following tables.
Drill Meterage from the Second Half of 2008
Meterage shows a significant decline in output after July, 2008 as development drilling of the Santa Eduwiges vein system wound down. The Company's exploration emphasis shifted to underground exploration for new high-grade gold-silver resources to support the Cusi pilot mining.

Santa Rosa "Stockwork" Zone
In plan view, the Santa Rosa "stockwork" zone occupies a 50 x 150 meter area that has been drilled to a depth of 50 meters below the 2000 Level of the Santa Eduwiges mine and continues for an unknown distance to depth. Mineralization consists of a strongly fractured, pervasively silicified and quartz veined zone. Argentite is the dominant silver mineral in the Santa Rosa "stockwork" zone and is associated with both quartz veinlets and as disseminated blebs and grains within crushed and broken rhyolite host.

Dia Bras Exploration Inc.: New Discovery of Disseminated Copper Silver Mineralization as a Potential Open Pit Target at the Bolivar Mine
MONTREAL, QUEBEC, Apr 06, 2009 (MARKET WIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) ("Dia Bras" or the "Corporation") is pleased to announce that exploration teams of its wholly owned Mexican subsidiary, Dia Bras Mexicana S.A. de C.V. encountered six areas of disseminated copper-silver skarn mineralization during on-going geologic studies, mapping, sampling, and drilling at its Bolivar mine, Chihuahua, Mexico. Copper-silver mineralization crops out in skarnitized carbonate rocks at their contact with the Piedras Verdes granodiorite stock and extends for two kilometers from Bolivar Northwest at the north end of the Bolivar District to El Gallo at the current southern limit of district exploration (See following Location Map).
To view the Location Map - Disseminated Copper-Silver Mineralization at the Bolivar Mine, Chihuahua, Mexico: http://www.diabras.com/en/newscenter/2009/DIBPr15_Figure1_Di…
Daniel Tellechea, President and Chief Executive Officer, says "The significance of these areas is not the resources currently defined but the potential that exists between them. Together these areas suggest that copper-silver mineralization continues for over two kilometers on surface and that presents potential for an open-pittable copper-silver resource." Exploration during 2009 is planned to sample and drill both the known resources and intervening ground to explore this target.
Currently Dia Bras operates the Bolivar underground pilot mining operation from two surface adits at the Bolivar Mine. Mining is advancing in skarn down-dip to the east, exploiting massive copper-zinc skarn mineralization that ranges from 2-12% copper and 5-40% zinc. However, it is the disseminated mineralization described in this release that presents potential for a low-cost, open-pit mining operation to feed Dia Bras' proposed new on-site mill (See Disseminated Copper Silver Progress Report).
At the northernmost areas, Bolivar NW and Rosario, north--south trending, disseminated chalcopyrite mineralization crops out over a 20-50 meters width, a 60-80 meters thickness and is open to the north and south along strike of the garnet-pyroxene skarn. Thus far exploration has defined Measured and Indicated resources shown in the table below (see September 25, 2008 SGS Geostat Resource Estimate in February, 2009 Bolivar Technical Report):
---------------------------------------------------------------------------------------------------------------------------------------------- Resources Cu Zn Au AuAreas Categories Tonnes % % gm/mt gm/mt-----------------------------------------------------------------------Bolivar NW Measured & Indicated 146,300 0.61 1.44 0.24 16.8-----------------------------------------------------------------------Rosario Measured & Indicated 17,200 0.66 6.18 0.1 17.1----------------------------------------------------------------------------------------------------------------------------------------------
The furthest hole north of Bolivar NW, DB04B026 advanced 277 meters northwest inclined 62 degrees through hornfelthized andesite and encountered disseminated and veinlet controlled chalcopyrite-pyrite in mixed dark garnet skarn and light green pyroxene hornfels. The hole encountered the following mineralization that suggests disseminated copper-silver mineralization continues further to the north under andesite.

Three hundred meters south, the Bismarck stope in the Bolivar mine hosts massive chalcopyrite-sphalerite mineralization that follows a fault and andesite dike plus disseminated chalcopyrite in massive calcite. The test stope was shut down because of grade too low for underground mining, but is within 40 meters of the surface and produced approximately 5000 m.t. of 0.68% Cu, 0.17% Zn, 0.48 gm Au/ m.t, 32.0 gm Ag/ m.t. while operating. Drilling encountered an additional 62 meters 0.87% Cu, 0.84% Zn, 0.1 gm Au/mt and 22.5 gm Ag/ mt 60 meters east of the stope. Sections through the Bismarck stope are open and mineralization continues in all directions. This zone is potentially open-pittable.
Two additional areas, Brecha Linda Surface and San Francisco Surface consist of fracture controlled and massive, chalcopyrite and sphalerite in andradite grossularite skarn that show strongly anomalous results from more than 500 surface samples (see Summary Results below) and produced significant drill intercepts in subsequent discovery drilling. Core hole DB09B281 drilled in these outcrops encountered a true width of 5.4 meters of 14.8 % Cu, 14.4% Zn, 0.6 gm Au/mt, and 330 gm Ag/mt.
Sample Summary Results (see Tables 2, 3, 4 and 5 in Disseminated Copper silver Progress Report)
-------------------------------------------------------------------------------------------------------------------------------------------------------- Number Sample Data Cu Zn Au AgArea Samples type type % % gm/mt gm/mt Reference----------------------------------------------------------------------------Bolivar 2x2 & Northwest 114 3x3 Panel Average 0.6 2.8 0.34 51 Table 2----------------------------------------------------------------------------Brecha Linda 100 2x2 Panel Average 0.3 0.7 0.1 14 Table 3----------------------------------------------------------------------------San Francisco Sur Upper Skarn 222 2x2 Panel Average 1.25 2.53 1.3 46 Table 4----------------------------------------------------------------------------San Francisco Sur Lower Skarn 88 2x2 Panel Average 0.8 0.0 0.7 32 Table 5--------------------------------------------------------------------------------------------------------------------------------------------------------
At San Francisco Sur, massive and disseminated chalcopyrite-bornite mineralization of the upper skarn crops out in garnet and pyroxene skarn. Mineralization extends east-southeast from the Pozo de Agua fault along the trace of host skarnitized carbonate and defines the southwest edge of the El Gallo area. Two hundred and twenty two rock chip samples collected from surface outcrops averaged 1.25% Cu, 2.53% Zn, 1.3 gm Au/mt, 46 gm Ag/mt (see Summary Table Above). Drill holes DB09B277 and DB09B278 drilled to test the skarn mineralization 10 meters down dip from surface outcrops encountered 11 meters of 0.71% Cu, 1.73% Zn, 0.3 gm Au/ m.t., and 56 gm Ag/ m.t. and 8.8 meters of 0.45% Cu, 1.85% Zn, 0.5 gm Au/ m.t., and 55 gm Ag/ m.t. respectively.
The southernmost of these mineralized areas, the El Gallo Upper Skarn, crops out on surface for approximately 400 meters. Here during the 2007 and 2008 drill program 20 holes penetrated disseminated and massive bornite, chalcopyrite, and sphalerite in andradite-grossularite skarn and so far have defined a small resource of 54,700 tons of 2.2 % copper, 4.7% zinc, 0.18 gm Au/ m.t., 47.5 gm Ag/ m.t. (See SGS Geostat calculations).
It is expected that the Bolivar copper-silver mineralization represents the first step toward the discovery of a copper porphyry skarn, as well as definition of low cost, open-pittable mill feed for Dia Bras' new on site mill.
Method of collection and analysis
All 2x2 and 3x3 meter chip panel samples were collected using single jacks and moils from painted panels then bagged and labeled as 3- to 5-kilogram sized samples. The samples averaged 3.8 kilogram in size and were sent by ALS Chemex Laboratories, Inc. ("ALS Chemex") transport to their Chihuahua, Mexico sample preparation facility.
Pulps were then sent by ALS Chemex of North Vancouver Assay Laboratory in Vancouver, BC, Canada for analysis. They were assayed for gold by 50 gram fire assay with AA finish and for silver by AA on 50 gram split sample. ALS Chemex analyzed the samples lead, zinc, and copper by Induction Coupled Plasma (ICP) and AA methods.
Quality control
The quality assurance-quality control (QA-QC) of Dia Bras and their contractors is as follows:
Samples are collected and handled only by Dia Bras authorized personnel, who collected them utilizing the methods described above. Samples were bagged and labeled with unique sample numbers on site then transported by Dia Bras personnel to the Dia Bras core handling facility and there stored for shipment. Weekly, ALS Chemex authorized personnel picked up and transported samples from Dia Bras core handling facility directly to their Chihuahua, Mexico sample prep facility. ALS Chemex Quality Assurance and Control procedures are described on their website at www.ALSchemex.com/mineral/quality. "Most ALS Chemex laboratories are registered or are pending registration to ISO 9001:2000 standards, and a number of analytical facilities have received ISO 17025 accreditations for specific laboratory procedures."

Three hundred meters south, the Bismarck stope in the Bolivar mine hosts massive chalcopyrite-sphalerite mineralization that follows a fault and andesite dike plus disseminated chalcopyrite in massive calcite. The test stope was shut down because of grade too low for underground mining, but is within 40 meters of the surface and produced approximately 5000 m.t. of 0.68% Cu, 0.17% Zn, 0.48 gm Au/ m.t, 32.0 gm Ag/ m.t. while operating. Drilling encountered an additional 62 meters 0.87% Cu, 0.84% Zn, 0.1 gm Au/mt and 22.5 gm Ag/ mt 60 meters east of the stope. Sections through the Bismarck stope are open and mineralization continues in all directions. This zone is potentially open-pittable.
Two additional areas, Brecha Linda Surface and San Francisco Surface consist of fracture controlled and massive, chalcopyrite and sphalerite in andradite grossularite skarn that show strongly anomalous results from more than 500 surface samples (see Summary Results below) and produced significant drill intercepts in subsequent discovery drilling. Core hole DB09B281 drilled in these outcrops encountered a true width of 5.4 meters of 14.8 % Cu, 14.4% Zn, 0.6 gm Au/mt, and 330 gm Ag/mt.

At San Francisco Sur, massive and disseminated chalcopyrite-bornite mineralization of the upper skarn crops out in garnet and pyroxene skarn. Mineralization extends east-southeast from the Pozo de Agua fault along the trace of host skarnitized carbonate and defines the southwest edge of the El Gallo area. Two hundred and twenty two rock chip samples collected from surface outcrops averaged 1.25% Cu, 2.53% Zn, 1.3 gm Au/mt, 46 gm Ag/mt (see Summary Table Above). Drill holes DB09B277 and DB09B278 drilled to test the skarn mineralization 10 meters down dip from surface outcrops encountered 11 meters of 0.71% Cu, 1.73% Zn, 0.3 gm Au/ m.t., and 56 gm Ag/ m.t. and 8.8 meters of 0.45% Cu, 1.85% Zn, 0.5 gm Au/ m.t., and 55 gm Ag/ m.t. respectively.
The southernmost of these mineralized areas, the El Gallo Upper Skarn, crops out on surface for approximately 400 meters. Here during the 2007 and 2008 drill program 20 holes penetrated disseminated and massive bornite, chalcopyrite, and sphalerite in andradite-grossularite skarn and so far have defined a small resource of 54,700 tons of 2.2 % copper, 4.7% zinc, 0.18 gm Au/ m.t., 47.5 gm Ag/ m.t. (See SGS Geostat calculations).
It is expected that the Bolivar copper-silver mineralization represents the first step toward the discovery of a copper porphyry skarn, as well as definition of low cost, open-pittable mill feed for Dia Bras' new on site mill.
Method of collection and analysis
All 2x2 and 3x3 meter chip panel samples were collected using single jacks and moils from painted panels then bagged and labeled as 3- to 5-kilogram sized samples. The samples averaged 3.8 kilogram in size and were sent by ALS Chemex Laboratories, Inc. ("ALS Chemex") transport to their Chihuahua, Mexico sample preparation facility.
Pulps were then sent by ALS Chemex of North Vancouver Assay Laboratory in Vancouver, BC, Canada for analysis. They were assayed for gold by 50 gram fire assay with AA finish and for silver by AA on 50 gram split sample.

Dia Bras Obtains 85% Recovery of Silver From Cusi Rocks
MONTREAL, QUEBEC, Jun 10, 2009 (Marketwire via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTUREIB) is pleased to report the results of metallurgical testing on silver-mineralized rock from its Cusi project. The testing was done under the direction of an independent engineer, Sr. Pedro Castillo C., at the Centro de Investigation de Materiales Avanzados (CIMAV) located in Chihuahua City, Chihuahua.
A representative sample was collected under the supervision of Sr. Castillo from 1,500 tonnes of rock (mined from the Santa Eduwiges and Santa Marina veins) stockpiled at the Company's Malpaso mill. The sample was reduced to 5 kg mass and processed using a combination of flotation and cyanidation methods. The results are shown in the tables below:
Flotation Method Mass Mass Assay Results Percent Recovery-------------------------------------------------------------------------Product grams % Ag, g/t Pb% Ag Pb------------------------------------------------------------------------- Concentrate 232.8 4.62 3743.2 53.91 54.96 59.6------------------------------------------------------------------------- Flotation tails 4808.7 95.38 148.5 1.77 45.04 4041-------------------------------------------------------------------------Cyanidation Method------------------------------------------------------------------------- Pregnant Solution 99.0 66.7------------------------------------------------------------------------- Residual Tails 4808.7 95.38 49.5 33.30-------------------------------------------------------------------------------------------------------------------------------------------------- Total Recovery 85.00 59.6-------------------------------------------------------------------------------------------------------------------------------------------------- Calculated Head 5041.5 100.0 314.5 4.18 100.0 100.0-------------------------------------------------------------------------
Sr. Castillo also took photomicrographs of flotation concentrates that show grains about 100 microns in size (-140 mesh or 0.1 mm) of interlocked sphalerite and galena. From this information, it has been determined that the best economic grind for Cusi rock is 50% passing 200 mesh (-0.074 mm) and that reagents of zinc sulfate and cyanide during flotation recovery will reduce zinc contents in the lead-silver concentrates.
Bottle roll tests of cyanide leaching show that 80% of silver in the tails is recovered in 16 hours, and that continuing the tests to 48 hours resulted in 83% recovery of silver, an increase of only 3%. These results indicate that cyanide-recoverable silver is captured in a short time and that longer residence time is not worth the cost.
Based on these metallurgical data, management has decided to re-start pilot mining at Cusi during August, 2009, and process the mineralized rock by flotation method and stockpile the flotation tails while cyanidation vats are being constructed. The vats will be completed within 6 months from the start of construction. Application for permits for cyanidation processing has been made and management expects approval within six months.
Similar metallurgical tests have been initiated on rock from the Promontorio mine as management expects to initiate pilot mining of this deposit during the third quarter of 2010.
Bolivar Production
Further to its May 29, 2009 news release, the transportation of mineralized rock from the Bolivar Mine to the Malpaso mill has been resumed Tuesday. The management revised its production forecast for Bolivar pilot-mining production to approximately 100,000 tonnes at average grades of 1.47% Cu and 9.16% Zn for 2009.

Schwer zu sagen.
Pilot-mining in Bolivar.
Pilot mining in Cusi gestoppt.
Wohl aus Geldmangel - aufgrund der stark gefallenen Metallpreise, daher auch kein Gewinn aus dem Boliavr pilot-mining, sogar das Gegenteil.
Aber: Beides weit fortgeschrittene Projekte.
Beide wirtschaftlich betreibbar, und mit weiterhin sehr guten Explorations-Aussichten. Siehe auch heutige news.
Hier wird solide und zielstrebig gearbeitet.
Vielleicht auch deshalb finden sich immer Geldgeber, die die PPs zeichnen.
Vielleicht fehlt es ein klein wenig an Marketing ?
Die Firma ist ja nahezu unbekannt.
Alles in allem glaube ich schon an Dia Bras - aber es ist ein langer Atem nötig ...

DIA BRAS: New Targets and High Grade, Silver-Mineralized Shoots Identified at the Cusi Project, Chihuahua, Mexico
MONTREAL, QUEBEC, Jul 23, 2009 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to report that exploration teams of Dia Bras Exploration, Inc.'s wholly owned Mexican subsidiary, Dia Bras Mexicana S.A. de C.V. have identified new targets and ore shoots of high grade silver mineralization in the vein systems present in the areas of the Santa Eduwiges and Promontorio mines as well as other nearby areas during the Company's ongoing geologic review studies, mapping, sampling, and diamond core drilling at its Cusi project in Chihuahua, Mexico. Silver mineralization occurs as mineralized shoots in veins and in the hanging wall and footwall zones of the structures. In addition, potentially-mineable silver mineralization has been identified in the zone called Santa Rosa Chimney (Santa Eduwiges area), where at least five structures converge and the possibility of wider mineralized zones in the area of intersection of two or more structures are high. Low grade oxidized mineralization in the San Antonio open pit is also potentially mineable.
The Santa Eduwiges and Promontorio areas host a series of veins that represent excellent exploration targets. Table 1 shows a compilation of the veins at Santa Eduwiges and Table 2 shows a compilation of the veins at Promontorio.

Santa Eduwiges
In the Santa Eduwiges mine area , a minimum of 8 structures occur that average 1.0 to 1.5 m wide and yield intercepts of over 300 g Ag/t. Several of these structures converge in a zone located in the hanging wall block of the Green Fault and result in a mineralized zone called the Santa Rosa Chimney. The surface expression of the Santa Rosa Chimney consists of a potentially open-pitable area that measures roughly 180 by 50 m with oxidized Ag mineralization contained in the wall rocks of the veins. The samples from the oxidized portion of the chimney (San Antonio pit) averages 60-65 g Ag/t and represents a potential of about 900,000-1,100,000 tonnes. Preliminary bottle roll tests yielded results of 50 to 70% recovery and further tests will be done.

Mineralized shoots occur along known structures and very often at the intersection of two or more structures. Over a distance of about 200 m and 150 m down dip, one of the veins corresponds to a previously unknown structure that is located between the Santa Marina and San Antonio veins. This structure tends to be parallel to Santa Marina and appears to join it somewhere near the Santa Rosa zone. Also in the Santa Eduwiges mine area, another two mineralized shoots were identified in the Tascates and La Mexicana veins, which are currently being defined by drilling.
Promontorio
The Promontorio area (see attached figure) is located 0.85 km northwest of Santa Eduwiges mine and hosts a series of mineralized structures. Several potential targets have been identified in this area, the most important of which appears to be the convergence of nearly all of them with the Promontorio vein in an area located immediately below level 11 of the Promontorio mine. The potential for high grade and bulk tonnage mineralization is high. In addition, the intersections between those structures and the Veta del Contacto that runs semi-perpendicular to those veins represent good targets that have not been tested.
The Veta del Contacto is a structure that runs more or less parallel to the Cusi Fault. Information obtained from historical reports, maps and sections indicates that the Veta del Contacto structure has several mineralized shoots, with values that range from 30 to 120 ounces (about 900 to 3,600 g/t) of silver per ton. Most of these mineralized shoots are defined by the intersection of the veins mentioned above with this structure. Drilling in this area is in a very early stage and only three holes have been drilled to date. The first hole cut only a narrow zone with poor mineralization. The second hole, however, intersected an old stope with a 3 m wide stockwork and breccia zone and a narrow quartz vein with strong argentite mineralization over the hanging wall. The stockwork and breccia zone continues in the footwall for about another 7 to 8 m along the hole. A third hole was drilled and hit the narrow vein over the hanging wall but could not cross the stope. Drilling in the area continues and assays are pending.

San Juan and Los Tajos
Two additional areas, the San Juan and Los Tajos areas, show good prospects for economic mineralization. The San Juan vein is a structure 0.80 to 1.2 m wide striking about 60 NE that occurs 1.8 km northwest of the Santa Eduwiges mine portal and can be followed for 0.5 km. Examination of old maps and sections indicates that this structure could host mineralization with high grade silver because grades over 800 Ag g/t are reported. This area is poorly known, and preliminary mapping and sampling were done over the area in order to identify drilling targets. The second area, which is called Los Tajos, is located 1.3 km SW of the Santa Eduwiges mine portal and corresponds to the SW projection of the Santa Eduwiges vein. The vein is intersected in this area by the La Gloria vein that strikes 28-30 NE. In addition, a total of 8 samples taken in the wall rock over an area of 120 by 15 m yielded an average grade of 65 Ag g/t. Historical surface sampling carried out by Panamericana S.A. de C.V. in 1991 yielded an average of 358 Ag g/t and 0.22 to 1.20 Au g/t along a distance of more than 500 m in veins that range in width from 0.80 m to 1.20 m.

A drilling program to continue testing the structures in the Santa Eduwiges mine area is planned. Sections of core from previous drilling have to be sampled where the core cut zones between veins in the Santa Rosa Chimney. Drilling in the "Veta del Contacto" is in progress and additional drill holes will be sited to test a portion of the vein that is located several meters to the east in the same structure. Surface mapping and sampling in the Promontorio area will continue. Review of the previous drilling carried out over the San Nicolas vein, located about 500 south of the Promontorio shaft, is in progress because a mineralized shoot with over 600 Ag g/t at the Providencia level elevation is mentioned in historical reports. The Providencia level is the level of underground workings that connects the Promontorio and Santa Eduwiges mines. Depending on time and availability, more work will be done in the areas of San Juan and Los Tajos.
Method of analysis
Diamond drill samples sent for analysis consisted of half NQ-size and BQ-size diamond core split on site, prepared by the ALS Chemex sample preparation laboratory in Chihuahua, Mexico, and assayed for Au by 50 g fire assay with AA finish, and for Ag by AA on 50 g split sample at the ALS Chemex North Vancouver Laboratory. Assays for Pb, Zn and Cu are done by Induction Coupled Plasma (ICP) at Chemex.

MONTREAL, QUEBEC, Jul 23, 2009 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to report that exploration teams of Dia Bras Exploration, Inc.'s wholly owned Mexican subsidiary, Dia Bras Mexicana S.A. de C.V. have identified new targets and ore shoots of high grade silver mineralization in the vein systems present in the areas of the Santa Eduwiges and Promontorio mines as well as other nearby areas during the Company's ongoing geologic review studies, mapping, sampling, and diamond core drilling at its Cusi project in Chihuahua, Mexico. Silver mineralization occurs as mineralized shoots in veins and in the hanging wall and footwall zones of the structures. In addition, potentially-mineable silver mineralization has been identified in the zone called Santa Rosa Chimney (Santa Eduwiges area), where at least five structures converge and the possibility of wider mineralized zones in the area of intersection of two or more structures are high. Low grade oxidized mineralization in the San Antonio open pit is also potentially mineable.
The Santa Eduwiges and Promontorio areas host a series of veins that represent excellent exploration targets. Table 1 shows a compilation of the veins at Santa Eduwiges and Table 2 shows a compilation of the veins at Promontorio.

Santa Eduwiges
In the Santa Eduwiges mine area , a minimum of 8 structures occur that average 1.0 to 1.5 m wide and yield intercepts of over 300 g Ag/t. Several of these structures converge in a zone located in the hanging wall block of the Green Fault and result in a mineralized zone called the Santa Rosa Chimney. The surface expression of the Santa Rosa Chimney consists of a potentially open-pitable area that measures roughly 180 by 50 m with oxidized Ag mineralization contained in the wall rocks of the veins. The samples from the oxidized portion of the chimney (San Antonio pit) averages 60-65 g Ag/t and represents a potential of about 900,000-1,100,000 tonnes. Preliminary bottle roll tests yielded results of 50 to 70% recovery and further tests will be done.

Mineralized shoots occur along known structures and very often at the intersection of two or more structures. Over a distance of about 200 m and 150 m down dip, one of the veins corresponds to a previously unknown structure that is located between the Santa Marina and San Antonio veins. This structure tends to be parallel to Santa Marina and appears to join it somewhere near the Santa Rosa zone. Also in the Santa Eduwiges mine area, another two mineralized shoots were identified in the Tascates and La Mexicana veins, which are currently being defined by drilling.
Promontorio
The Promontorio area (see attached figure) is located 0.85 km northwest of Santa Eduwiges mine and hosts a series of mineralized structures. Several potential targets have been identified in this area, the most important of which appears to be the convergence of nearly all of them with the Promontorio vein in an area located immediately below level 11 of the Promontorio mine. The potential for high grade and bulk tonnage mineralization is high. In addition, the intersections between those structures and the Veta del Contacto that runs semi-perpendicular to those veins represent good targets that have not been tested.
The Veta del Contacto is a structure that runs more or less parallel to the Cusi Fault. Information obtained from historical reports, maps and sections indicates that the Veta del Contacto structure has several mineralized shoots, with values that range from 30 to 120 ounces (about 900 to 3,600 g/t) of silver per ton. Most of these mineralized shoots are defined by the intersection of the veins mentioned above with this structure. Drilling in this area is in a very early stage and only three holes have been drilled to date. The first hole cut only a narrow zone with poor mineralization. The second hole, however, intersected an old stope with a 3 m wide stockwork and breccia zone and a narrow quartz vein with strong argentite mineralization over the hanging wall. The stockwork and breccia zone continues in the footwall for about another 7 to 8 m along the hole. A third hole was drilled and hit the narrow vein over the hanging wall but could not cross the stope. Drilling in the area continues and assays are pending.

San Juan and Los Tajos
Two additional areas, the San Juan and Los Tajos areas, show good prospects for economic mineralization. The San Juan vein is a structure 0.80 to 1.2 m wide striking about 60 NE that occurs 1.8 km northwest of the Santa Eduwiges mine portal and can be followed for 0.5 km. Examination of old maps and sections indicates that this structure could host mineralization with high grade silver because grades over 800 Ag g/t are reported. This area is poorly known, and preliminary mapping and sampling were done over the area in order to identify drilling targets. The second area, which is called Los Tajos, is located 1.3 km SW of the Santa Eduwiges mine portal and corresponds to the SW projection of the Santa Eduwiges vein. The vein is intersected in this area by the La Gloria vein that strikes 28-30 NE. In addition, a total of 8 samples taken in the wall rock over an area of 120 by 15 m yielded an average grade of 65 Ag g/t. Historical surface sampling carried out by Panamericana S.A. de C.V. in 1991 yielded an average of 358 Ag g/t and 0.22 to 1.20 Au g/t along a distance of more than 500 m in veins that range in width from 0.80 m to 1.20 m.

A drilling program to continue testing the structures in the Santa Eduwiges mine area is planned. Sections of core from previous drilling have to be sampled where the core cut zones between veins in the Santa Rosa Chimney. Drilling in the "Veta del Contacto" is in progress and additional drill holes will be sited to test a portion of the vein that is located several meters to the east in the same structure. Surface mapping and sampling in the Promontorio area will continue. Review of the previous drilling carried out over the San Nicolas vein, located about 500 south of the Promontorio shaft, is in progress because a mineralized shoot with over 600 Ag g/t at the Providencia level elevation is mentioned in historical reports. The Providencia level is the level of underground workings that connects the Promontorio and Santa Eduwiges mines. Depending on time and availability, more work will be done in the areas of San Juan and Los Tajos.
Method of analysis
Diamond drill samples sent for analysis consisted of half NQ-size and BQ-size diamond core split on site, prepared by the ALS Chemex sample preparation laboratory in Chihuahua, Mexico, and assayed for Au by 50 g fire assay with AA finish, and for Ag by AA on 50 g split sample at the ALS Chemex North Vancouver Laboratory. Assays for Pb, Zn and Cu are done by Induction Coupled Plasma (ICP) at Chemex. Samples for the Los Tajos area and San Antonio pit were prepared at the Chemex lab facility in Chihuahua, Mexico, and analyzed by ICP and AA methods at their facilities in Vancouver, Canada. The channel surface samples for the San Juan were analyzed by AA and FA at the Malpaso mill laboratories facilities.
Quality control
The quality assurance-quality control (QA-QC) of Dia Bras and their contractors is as follows:
Samples are collected and handled only by Dia Bras authorized personnel, who collected them utilizing the methods described above. Samples were bagged and labeled with unique sample numbers on site then transported by Dia Bras personnel to the Dia Bras core handling facility and there stored for shipment.

Dia Bras Develops Access to Massive High-Grade Copper-Zinc Mineralization at Bolivar
* Press Release

* On Wednesday September 30, 2009, 9:02 am EDT
MONTREAL, QUEBEC--(Marketwire - 09/30/09) - Dia Bras Exploration Inc. (TSX-VIB - News) is pleased to report positive results of continued drilling and underground drifting programs at its Bolivar pilot mine, in Chihuahua State, Mexico. Of particular note is the ongoing mine development of the Guadalupe zone, where access drifts in three levels are delineating a high-grade massive copper-zinc sulfide zone with grades higher than previously anticipated.
The Guadalupe zone was first discovered with two drill hole intercepts in 2004 and mine development access in the area was intermittent as the Company was focusing on mining the Titanic and Selena zones in those years. Further drilling in early 2009 of the Guadalupe zone identified the larger extent of mineralization prompting further development efforts in the area. Mining began on Levels 3 & 7 during March 2009 and on Level 8 during May 2009. Commenting on the results, Daniel Tellechea President and CEO stated "The economic importance of this zone is increasing more-and-more as work progresses. Sampling of drifts and stopes demonstrates the high grade nature of the Guadalupe mineralization. The extent of the Guadalupe zone, however, has not been determined as it is still open in all directions. The results reported here also demonstrate the Company's ability to continue shipping high-grade rock to its Malpaso mill until the new mill is operational on site at the Bolivar mine."

Dia Bras Discovers Further Silver Vein Extensions at Depth and Initiates Expanded Development at its Cusi Silver Project
MONTREAL, QUEBEC, Dec 08, 2009 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to announce that it has initiated further development of the San Antonio and Mexicana veins of the Santa Eduviges mine within its Cusi property with the objective of increasing shipment of silver-mineralized rock to its Malpaso mill, which is located only 35 km from the mine. Recent drill results at both the San Antonio and La Mexicana veins have delineated extensions of silver mineralization as well as intercepting previously unknown veins at depth (see table below). In addition, the company plans to restart the development of its Promontorio silver mine (also within its Cusi property) in early 2010 to expand silver production rates.
"We consider that the latest drill results at the San Antonio and Mexicana veins are further evidence of the exploration upside of these areas and provide support to our pilot mining plan for 2010. In addition, we are pleased with Cusi's mining and processing tests during the month of November. The recent construction completion of the cyanidation vat leaching circuit enhances the economics of the Cusi project and its growth prospects" said Daniel Tellechea, President and CEO of Dia Bras.

Pilot Mining Update For Cusi
Mining in the San Antonio vein is currently being done from underground workings at the 1970 m level with shipments to Malpaso of 50-70 tons per day (tpd). Rock from this program is being processed as part of the mill optimization program that should result in increased silver recovery in preparation for processing of higher daily tonnages, based on the Company's previous metallurgical studies.
A ramp is being driven to the 1940 m level in order to provide access to recently discovered, high grade silver mineralization found in drill holes below the current workings, as shown in the accompanying longitudinal section that can be accessed at http://www.diabras.com/en/newscenter/2009/sanantonio.pdf. The Company's objective is to have six operating stopes within two months, which will result in shipments of 150-180 tpd by early March, 2010. In addition, development of the Mexicana vein will be done concurrently with development of the San Antonio vein.
In preparation for pilot mining, the Company has been optimizing the Malpaso circuit of the Malpaso mill in order to achieve maximum silver recovery. During November, the mill processed 1,214 tonnes at an average grade of 344 g/t Ag, 0.51% Pb and 1.17% Zn. Tuning of the mill has included varying reagent mixes and retention times in the flotation cells. Various options have been considered with the objective of determining how to produce the most economic silver concentrate. The most favorable option has been selected and has been implemented. During November, recovery of silver by only the flotation method averaged 62.8%.
The tailings from this work are being stored separately in order to be re-processed in the vat leach circuit, which has been commissioned and is in start-up mode.
Vat Leach Operating Update
Construction of vats and associated circuits for leaching of silver from flotation tailings was started on August 3 and was completed in mid-November. The decision to construct the vats was based on the results of metallurgical testing that demonstrated total silver recoveries of 80-85% can be achieved with a combination of flotation and leaching methods (see press release of June 10, 2009).
The first silver precipitate derived from the vat leaching process has been removed from the filters and will be smelted to produce the first silver dore bar this week.
Promontorio Mine Development Plan Update
Dia Bras plans to expand silver production from the Cusi property in late 2010 by developing the Promontorio mine beginning in early 2010. When the Company's new mill at the Bolivar site is commissioned, the Triunfo circuit of the Malpaso mill will become available to process rock from Promontorio. The objective is to have the Santa Eduviges and Promontorio mines developed such that the mines will produce 400-500 tpd during 2011, and to increase mine production in the following years.

Dia Bras Drills More High Grade Silver at Cusi Project and Gives Outlook for 2010
MONTREAL, QUEBEC, Dec 16, 2009 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to report the results of drilling of the Veta del Contacto target at its Cusi project. The drilling was conducted to test the un-mined portions of the vein above and below old workings.
Veta del Contacto is one of several veins within a network of veins centered on the Promontorio mine. Several of these veins were partially mined by prior operators, mainly during the 1930s; historical records of production, however, are incomplete. Dia Bras\' work since 2007 has shown that large portions of the veins have not been mined.
The accompanying map and cross sections (http://www.diabras.com/en/newscenter/2009/veta_de_contacto.p… show the relationships between the mined-out portion of Veta del Contacto and Dia Bras drill holes. The table below shows the results from several drill holes:

Commenting on these results, Mr. Daniel Tellechea, President of Dia Bras, stated, \"The Promontorio mine is the second silver producing operation that we want to develop to ship mineralized material to our Malpaso mill. Together with the Santa Eduviges mine, Promontorio should increase silver production for Dia Bras during 2010-2011. These results confirm the continuation laterally and at depth of rich veins and underscore the exploration potential of Cusi\'s Promontorio area. Now that we have the cyanidation recovery circuits operational, we can, based on our metallurgical testing, achieve 80-85% recovery of silver by a combination of recovery by flotation and cyanidation methods.\"
2010 Cusi Project Exploration Outlook
Three surface drill rigs are now drilling various targets on the property. The first rig is conducting development drilling at the San Antonio-Santa Rosa area where 850 m of core drilling are planned.
The second rig is drilling the Veta del Contacto vein and has encountered a previously unknown vein above Veta del Contacto. Several holes will be drilled to define this new vein, and the rig will then be moved across the valley to drill deeper holes below the old Veta del Contacto stope where earlier holes have encountered kilo levels of silver (see table above).
The third rig is conducting development drilling of the upper El Gallo vein of the Promontorio mine, with about 3,700 m planned for the program. The results of this drilling will guide the mine plan for this area. The ramps previously developed by Dia Bras allow relatively quick development of this vein, which has only been mined to a minor extent. The objective is to have the Promontorio mine developed sufficiently by late 2010 to initiate pilot mining that is expected to produce an additional 250 tonnes per day of mineralized rock during 2011, which will be shipped to the Company\'s Malpaso mill for processing and complement the production from Santa Eduviges.
The \"alphabet\" veins of the Promontorio mine (vein C, H, J, K, etc.) that intersect the main Promontorio vein are mined out above Level 7 but only for a strike distance of about 60 m, where grades were apparently higher adjacent to the Cusi fault. There is significant un-mined lateral extension to these veins, as revealed by the Dia Bras ramps and drilling.
After drilling at Veta del Contacto is completed, the rig will be moved to La India, probably late in the second quarter of 2010, where 2,500 m in 8-10 holes are planned. The drilling will be conducted after the area is mapped and sampled, which should be completed during the first quarter. The rig will then be moved to San Juan, where six holes totaling 1,000-1,200 m are planned.
An area located about 3 km NW of the San Juan deposit, La Matulera, will be explored during the third quarter by soil sampling and reconnaissance mapping. This area is on a mesa-like area that contains small hills that are the result of silicified bedrock being resistant to weathering. Abundant quartz vein float litters the hillsides, and the vein textures indicate that the vein material was eroded from veins high in the epithermal system, above the precious metals zone. This is a low cost program that has the objective of identifying drill targets in a previously unexplored area.
In addition, two underground drill rigs will be used in the Santa Eduviges and Promontorio mines to provide additional data for mine planning.
43-101 Update
Dia Bras has contracted with Geostat Systems International, Inc. of Montreal to update the 43-101 report that Geostat completed in June, 2008. The report stated that the Santa Eduviges and Promontorio deposits contained Measured + Indicated Resources of 234,000 tonnes containing 1,413,260 ounces of silver and Inferred Resources of 1,394,000 tonnes, containing 8,434,810 ounces of silver. The full report is available on Dia Bras\' web page www.diabras.com .
The updated 43-101 report is expected to be completed during the second quarter of 2010.
Method of Analysis
Samples were prepared at the ALS Chemex lab facility in Chihuahua, Mexico, and analyzed by ICP and AA methods at their facilities in Vancouver, Canada. Samples are assayed for Au by 50 g fire assay with AA finish, and for Ag by AA on 50 g split sample at the ALS Chemex North Vancouver Laboratory. Samples assayed for Pb, Zn and Cu are analyzed by Induction Coupled Plasma (ICP) at ALS Chemex.
Quality Control
The quality assurance-quality control (QA-QC) of Dia Bras has been described in detail in both RPA\'s 43-101 reports of December, 2006, at Cusi and October, 2005, for Bolivar.

Dia Bras\' work since 2007 has shown that large portions of the veins have not been mined.
The accompanying map and cross sections (http://www.diabras.com/en/newscenter/2009/veta_de_contacto.p… show the relationships between the mined-out portion of Veta del Contacto and Dia Bras drill holes. The table below shows the results from several drill holes:

Commenting on these results, Mr. Daniel Tellechea, President of Dia Bras, stated, \"The Promontorio mine is the second silver producing operation that we want to develop to ship mineralized material to our Malpaso mill. Together with the Santa Eduviges mine, Promontorio should increase silver production for Dia Bras during 2010-2011. These results confirm the continuation laterally and at depth of rich veins and underscore the exploration potential of Cusi\'s Promontorio area. Now that we have the cyanidation recovery circuits operational, we can, based on our metallurgical testing, achieve 80-85% recovery of silver by a combination of recovery by flotation and cyanidation methods.\"
2010 Cusi Project Exploration Outlook
Three surface drill rigs are now drilling various targets on the property. The first rig is conducting development drilling at the San Antonio-Santa Rosa area where 850 m of core drilling are planned.
The second rig is drilling the Veta del Contacto vein and has encountered a previously unknown vein above Veta del Contacto. Several holes will be drilled to define this new vein, and the rig will then be moved across the valley to drill deeper holes below the old Veta del Contacto stope where earlier holes have encountered kilo levels of silver (see table above).
The third rig is conducting development drilling of the upper El Gallo vein of the Promontorio mine, with about 3,700 m planned for the program. The results of this drilling will guide the mine plan for this area. The ramps previously developed by Dia Bras allow relatively quick development of this vein, which has only been mined to a minor extent. The objective is to have the Promontorio mine developed sufficiently by late 2010 to initiate pilot mining that is expected to produce an additional 250 tonnes per day of mineralized rock during 2011, which will be shipped to the Company\'s Malpaso mill for processing and complement the production from Santa Eduviges.
The \"alphabet\" veins of the Promontorio mine (vein C, H, J, K, etc.) that intersect the main Promontorio vein are mined out above Level 7 but only for a strike distance of about 60 m, where grades were apparently higher adjacent to the Cusi fault. There is significant un-mined lateral extension to these veins, as revealed by the Dia Bras ramps and drilling.
After drilling at Veta del Contacto is completed, the rig will be moved to La India, probably late in the second quarter of 2010, where 2,500 m in 8-10 holes are planned. The drilling will be conducted after the area is mapped and sampled, which should be completed during the first quarter. The rig will then be moved to San Juan, where six holes totaling 1,000-1,200 m are planned.
An area located about 3 km NW of the San Juan deposit, La Matulera, will be explored during the third quarter by soil sampling and reconnaissance mapping. This area is on a mesa-like area that contains small hills that are the result of silicified bedrock being resistant to weathering. Abundant quartz vein float litters the hillsides, and the vein textures indicate that the vein material was eroded from veins high in the epithermal system, above the precious metals zone. This is a low cost program that has the objective of identifying drill targets in a previously unexplored area.
In addition, two underground drill rigs will be used in the Santa Eduviges and Promontorio mines to provide additional data for mine planning.
43-101 Update
Dia Bras has contracted with Geostat Systems International, Inc. of Montreal to update the 43-101 report that Geostat completed in June, 2008. The report stated that the Santa Eduviges and Promontorio deposits contained Measured + Indicated Resources of 234,000 tonnes containing 1,413,260 ounces of silver and Inferred Resources of 1,394,000 tonnes, containing 8,434,810 ounces of silver. The full report is available on Dia Bras\' web page www.diabras.com .
The updated 43-101 report is expected to be completed during the second quarter of 2010.
Method of Analysis
Samples were prepared at the ALS Chemex lab facility in Chihuahua, Mexico, and analyzed by ICP and AA methods at their facilities in Vancouver, Canada. Samples are assayed for Au by 50 g fire assay with AA finish, and for Ag by AA on 50 g split sample at the ALS Chemex North Vancouver Laboratory. Samples assayed for Pb, Zn and Cu are analyzed by Induction Coupled Plasma (ICP) at ALS Chemex.
Quality Control
The quality assurance-quality control (QA-QC) of Dia Bras has been described in detail in both RPA\'s 43-101 reports of December, 2006, at Cusi and October, 2005, for Bolivar.
The technical content of this news release has been approved by Thomas L. Robyn, Ph.D., RPG, CPG and Director of Dia Bras, a Qualified Person as defined in NI 43-101.

Dia Bras Pours the First Silver Dore Bar From Cusi Rock
MONTREAL, QUEBEC, Dec 17, 2009 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to announce that it has produced the first silver dore from the cyanide leaching circuits at its Malpaso mill. Construction of the leach circuits began in August, and the first leaching of mill tailings commenced during late November.
"This is an exciting step forward for us", said Daniel Tellechea, President of Dia Bras. "With the leaching circuits operational, our recovery of silver will be increased significantly, based on our metallurgical testing and this pour."
The photo below shows the first bar (http://www.diabras.com/en/newscenter/2009/dorebar.jpeg), which is held by Daniel Tellechea, President. Philip Renaud, Chairman of Dia Bras is to his left, while Thomas Robyn, Director, is to his right.
The bar weighs 13.23 kg and contains 42.6% silver (about 172 ounces of silver), 32.4% lead, 6.0% copper, 1.7% zinc, and 17.3% other metals. The low gold content in the bar, 3.5 g/t, reflects the low gold content of the Cusi mineralization. These assays were prepared and analyzed at the Company's lab at its Malpaso mill; check assays will be analyzed by ALS Chemex.
The metallurgical balance indicated by these results is as follows: recovery of silver by flotation method was 68.26%, and an additional 12.19% was recovery from the tailings, resulting in an overall silver recovery of 80.45%. Management is confident that as the leaching circuits are adjusted with further operation, silver recovery will improve, as this result is in the lower part of the range of the 80-85% recovery indicated by metallurgical testing. In addition, these adjustments should increase the silver content in the dore bars.
The company currently has two vats in operation, and an additional two vats will be added to the system. Construction of the new vats is scheduled to begin in early January and will be completed within a month. Additional vats will be added immediately after those are constructed, with the expectation that six vats will be operational by the end of March, 2010.
Each vat has a design capacity of 400 tonnes of tailings and has a one-week cycle for leaching, resulting in 1,600 tonnes per month capacity for each vat. With four vats operational, the system can process 6,400 tonnes of tailings per month. With six vats operational, one will be used as a reservoir, and five vats would process tailings, resulting in a monthly capacity of 8,000 tonnes per month.

Dia Bras Reports High Grade Gold at Surface on Its La Cascada Prospect of the Bolivar Property
MONTREAL, QUEBEC, Jan 25, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to report that it has received high grade gold assays from surface channel samples collected in its initial exploration program on the La Cascada prospect of its Bolivar property. La Cascada lies only 2.5 km south of Cieneguita, where Dia Bras has its camp, offices and maintenance facilities for its Bolivar mine operations.
Commenting on the results, Daniel Tellechea, President of Dia Bras, stated, "We are encouraged by the high grade results discovered at surface outcrops that are as high as 15 grams per tonne over a 3 metre channel. This prospect is near our existing infrastructure and lies within the prolific Sierra Madre gold-silver belt of northwestern Mexico that hosts several multi-million ounce gold deposits."
Bolivar has never been explored for gold by modern methods, yet the property is surrounded by several historical gold producing mines and currently well known deposits, such as Goldcorp's El Sauzal mine (1.2 million ounces of gold produced), located 12 km southeast of the prospect and Coeur's Palmarejo deposit (1.1 million ounces of gold plus 88 million ounces of silver), located 50 km to the northwest (see attached Regional Map (http://www.diabras.com/en/newscenter/2010/Cascada%20Regional…
Geology
The La Cascada prospect is underlain by an extensive and thick sequence of pyroclastic breccias and agglomerates, including lapilli tuff, landslide mega-breccias, and tuff breccias mixed with andesitic flows, all derived from andesitic volcanism. The basal andesitic flow contains volcanic blocks and bombs, lapilli and ash tuff.
Detailed geologic mapping and sampling are in progress with the objective of identifying drill sites.
Mineralization
From the La Cascada central zone towards the north - northeast, gold anomalies occur along contact zones of discordant veins and veinlets of limonite, sponge limonite and hematite with pervasive quartz and fine-medium pyrite (see attached La Cascada Prospect Au Values (http://www.diabras.com/en/newscenter/2010/Cascada%20Prospect… and Anomalies maps (http://www.diabras.com/en/newscenter/2010/Cascada%20Prospect… In addition, a stratiform zone is hosted by intensely argillized, pyroclastic breccia and infill tuff breccia bounded by interlayered andesitic flows.
From the central zone towards the southwest is a topographically higher area where zones of veining with disseminated sulphides (galena, sphalerite, chalcopyrite) occur.
Extensive argillic alteration (kaolinite - quartz - hematite - limonite) occurs over a 100 hectare area with pervasive quartz, fine-medium pyrite and partial silicification of the matrix.
To date, two possible gold-related assemblages have been identified:
1. Quartz - Pyrite - Sericite - Alunite? - Dickite?: Mainly in altered pyroclastic breccia zones and infill breccia tuffs forming a stratabound altered unit cut by anastomosed veins/veinlets with sponge limonite, limonite, hematite and quartz.
2. Sponge Limonite - Jarosite - Hematite - Goethite: Mainly forming halos in fractures or fillings forming veins and veinlets crossing altered host rocks.
This is the first systematic channel sampling on the prospect that covers an area of 2,000 by 3,000 metres. Table 1 below shows selected results from sampling at La Cascada. Complete results are given in the accompanying maps that show sample locations and alteration patterns.

Dia Bras Develops More High-Grade Rock at Bolivar
MONTREAL, QUEBEC, Mar 02, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to report the results of continued drilling, sampling and underground drifting at its Bolivar pilot-mine, Chihuahua State, Mexico. Sampling of drifts and stopes continues to demonstrate the high-grade nature of the mineralization at various areas in the mine.
"Our exploration and development activities in the Bolivar mine continue to locate high-grade zones that allow us to ship rock to Malpaso for processing and continue to increase the Corporation's knowledge on controls on mineralization in the mine," stated Daniel Tellechea, President & CEO. "In addition to the work being done on the high-grade zones, we are exploring and developing areas that will be mined for rock that will be processed at the Corporation's new mill site, located only 6 km from the mine. For example, a drift is being extended from the San Francisco zone to El Gallo, where significant tonnage for our new mill occurs, and development is progressing at La Increible."
Drill hole 316 is particularly encouraging because it cut very high-grade mineralization 80 m SSE of Guadalupe (see attached figure: http://www.diabras.com/en/newscenter/2010/guadalupe.jpg), which indicates that the trend of mineralization is present a significant distance from the current workings. The Corporation's mine geologists now believe that the Selena-Guadalupe bodies are on a mineralized trend that is parallel to the Rodolfo-Rosario trend, which indicates significant exploration potential both to the NNW and SSE of these bodies. Drill hole 311 cut the same body as 316, with lower grade, but the textures and mineralogy indicate that the trend continues to the SSE.

Dia Bras Expands Gold Mineralization At The La Cascada High-Sulfidation Gold Prospect At The Bolivar Property
MONTREAL, QUEBEC, Mar 23, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to report the results of continued, detailed sampling and mapping plus X-Ray diffraction studies at the La Cascada high-sulfidation gold prospect of its Bolivar property in Chihuahua State, Mexico. La Cascada is located only 2.5 km south of Dia Bras' support and maintenance facilities at its Cieneguita camp. Although gold mineralization in the area has been known by local prospectors, the extensive area of alteration related to the La Cascada prospect is not recorded on any geologic maps of the region.
"La Cascada is becoming an important project to us," stated Daniel Tellechea, President and CEO, "because continued work has demonstrated that the intensely altered and silicified portions of the area that contain elevated gold values is more extensive than previously thought. This presents a strong possibility that this area could host an important and open-pitable gold deposit. We are aggressively pursuing exploration in this area with the objective of drilling it soon."

The zone of high-sulfidation gold mineralization is characterized by an extensive zone of strong, advanced argillic alteration of the host andesite extending at least 6 km2 that contains areas of silicification, and the zone is open in several directions. The silicified zones are structurally controlled and occur as concentric zones of silicification expressed by an outer zone of granular silica replacement of andesite, an intermediate zone where silicification has destroyed feldspars and original textures, and a core zone of vuggy silica where all original features of the host rock have been destroyed.
X-ray diffraction analysis conducted by the Servicio Geologico Mexicano's Chihuahua office confirms the presence of hydrothermal clays, the most important of which is pyrophyllite, a clay mineral associated with higher temperature zones in a high-sulfidation gold system. The report may be viewed on Dia Bras' website (http://www.diabras.com/en/newscenter/2010/xrd_report.pdf). In La Cascada, it occurs in outcrops of vuggy silica and advanced argillic alteration.
The La Cascada mineralization has characteristics similar to several multi-million ounce high-sulfidation gold deposits, such as the gold association with structurally controlled vuggy silica zones, the style of alteration zonation, association with copper and arsenic, presence of pyrophyllite, etc. La Cascada is notably similar to the El Sauzal deposit, which is located less than 20 km to the southeast and is on the same regional, NNW-trending major structural zone.
The relationship of gold content and alteration has been confirmed by assay results from the various alteration zones present at La Cascada. The Company's geologists have collected over 61 channel and chip samples within the La Cascada prospect, with the following results:
1. Only samples collected from zones of silicification and veining exceed 1.0 g/t Au and range up to 15.8 g/t (see press release of January 25, 2010). To date, 16 samples have been collected from silicified and brecciated zones that returned more than 1 g/t Au.2. Samples collected from zones of strong advanced argillic alteration with granular silica texture return grades ranging from 0.2-1.0 g/t Au.3. Samples collected from zones of moderately-developed advanced argillic alteration return grades of 0.1-0.2 g/t Au.4. Samples collected from zones of weak argillic alteration return grades of less than 0.1 g/t Au.

Dia Bras Reports More High-Grade Gold Samples at the La Cascada High-Sulfidation Gold Prospect at the Bolivar Property
MONTREAL, QUEBEC, Apr 06, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to report more assay results from the La Cascada high-sulfidation gold prospect of its Bolivar property in Chihuahua State, Mexico. La Cascada is located only 2.5 km south of Dia Bras' support and maintenance facilities at its Cieneguita camp.
"These results reinforce our earlier data that show La Cascada is a significant gold prospect," stated Daniel Tellechea, President and CEO. "These latest sample assays demonstrate that the silicified and brecciated bedrock consistently returns potentially-economic grades of gold, with values in outcrop up to 7 g/t gold. We have high grades of gold in outcrop over a distance of 2,500 metres, an indication of the breadth and strength of this mineralized area. Even though results from another 35 samples from La Sidra are yet to be received, we are convinced that this area is an important prospect, and we are proceeding with a geophysical survey that will assist in defining drill targets."

Dia Bras Drills More High-Grade Silver Mineralization at its Cusi Project
MONTREAL, QUEBEC, Apr 07, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to announce more high-grade results from exploration and development drilling at the Promontorio mine area at Dia Bras' Cusi Property, which is being conducted to develop additional resources in support of an updated resource estimate and mine plan for this mine. The El Gallo, El Gallo Back and Transversal veins are part of the Promontorio vein system (El Gallo map http://www.diabras.com/en/newscenter/2010/El_Gallo_DH_PRV3.p… and drilling is designed to identify areas that will be developed during 2010 and pilot-mined in 2011. Please see the latest results in the table below.
In addition, drilling of the San Antonio and San Antonio A veins (San Antonio map http://www.diabras.com/en/newscenter/2010/San_Antonio_Area_P… of the Santa Eduviges vein system continues to identify blocks of mineralized rock that will be pilot-mined during 2010.
The Promontorio veins are high in silver and low in base metals, which indicate that in this area the veins are in the upper portion of the zoned epithermal system. The Santa Eduviges-San Antonio-Santa Marina area consists of multiple fracture-filled, quartz-carbonate veins containing high amounts of sulfide minerals that are typical of the middle portion (intermediate Pb, Zn, Cu) of the Ag zone in a zoned, low-sulfidation, epithermal vein system.
Dr. Thomas L. Robyn, Director and Head of Exploration for the Corporation, stated, "These exploration results show that the El Gallo vein of the Promontorio mine is well mineralized for silver. A ramp developed by Dia Bras has accessed the El Gallo vein and will be a starting point for pilot-mining of this vein system in 2011."

Pilot-Mining
The objective of pilot-mining the Cusi mineralization is to obtain factual information on the metallurgy of silver, lead and zinc mineralization, recovery rates, per tonne revenues at various commodity prices, mining costs and other factors. This information is essential for evaluation of the property's economic potential.
Results from drilling on El Gallo and other veins of the Promontorio mine are being compiled with the objective that a mine plan will be completed in early July, 2010. Development of the identified mineralized blocks will then begin in order to commence pilot-mining of Promontorio in early 2011. Ongoing pilot-mining will continue at the Santa Eduviges mine of the Cusi Property, and production from Promontorio will be added to that from Santa Eduviges and could significantly increase the value of mineralized rock to be processed at Dia Bras' wholly-owned Malpaso Mill, located just 36 kilometres from the Cusi Property.
Vat Construction
Two additional leach vats are under construction at the Corporation's Malpaso mill and a fifth is planned. Vats #3 and #4 will be completed during mid-April and will then be loaded with mill tailings for leach processing. These two additional vats will raise the leach capacity to an average of 200 tonnes per day. The fifth vat is scheduled to be operational during mid-May.
The Corporation has concluded a smelting and purchase agreement with Penoles and during March shipped eight dore bars totaling 114.4 kilos; the total silver content will be reported on completion of smelting and refining.
43-101 Update
Dia Bras has commissioned Geostat (SGS Canada, Inc.) of Montreal, Quebec, to update the resource calculation for the Cusi project that Geostat completed in May, 2008 (please see Dia Bras' news release of May 1, 2008). This calculation resulted in 2.12 million ounces of AgEq in the Measured plus Indicated categories and 14.6 million ounces of AgEq in the Inferred category for Santa Eduviges and Promontorio. A site visit by Geostat personnel was done during February 15-19 as part of the update.

MONTREAL, QUEBEC, Apr 07, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to announce more high-grade results from exploration and development drilling at the Promontorio mine area at Dia Bras' Cusi Property, which is being conducted to develop additional resources in support of an updated resource estimate and mine plan for this mine. The El Gallo, El Gallo Back and Transversal veins are part of the Promontorio vein system (El Gallo map http://www.diabras.com/en/newscenter/2010/El_Gallo_DH_PRV3.p… and drilling is designed to identify areas that will be developed during 2010 and pilot-mined in 2011. Please see the latest results in the table below.
In addition, drilling of the San Antonio and San Antonio A veins (San Antonio map http://www.diabras.com/en/newscenter/2010/San_Antonio_Area_P… of the Santa Eduviges vein system continues to identify blocks of mineralized rock that will be pilot-mined during 2010.
The Promontorio veins are high in silver and low in base metals, which indicate that in this area the veins are in the upper portion of the zoned epithermal system. The Santa Eduviges-San Antonio-Santa Marina area consists of multiple fracture-filled, quartz-carbonate veins containing high amounts of sulfide minerals that are typical of the middle portion (intermediate Pb, Zn, Cu) of the Ag zone in a zoned, low-sulfidation, epithermal vein system.
Dr. Thomas L. Robyn, Director and Head of Exploration for the Corporation, stated, "These exploration results show that the El Gallo vein of the Promontorio mine is well mineralized for silver. A ramp developed by Dia Bras has accessed the El Gallo vein and will be a starting point for pilot-mining of this vein system in 2011."

Pilot-Mining
The objective of pilot-mining the Cusi mineralization is to obtain factual information on the metallurgy of silver, lead and zinc mineralization, recovery rates, per tonne revenues at various commodity prices, mining costs and other factors. This information is essential for evaluation of the property's economic potential.
Results from drilling on El Gallo and other veins of the Promontorio mine are being compiled with the objective that a mine plan will be completed in early July, 2010. Development of the identified mineralized blocks will then begin in order to commence pilot-mining of Promontorio in early 2011. Ongoing pilot-mining will continue at the Santa Eduviges mine of the Cusi Property, and production from Promontorio will be added to that from Santa Eduviges and could significantly increase the value of mineralized rock to be processed at Dia Bras' wholly-owned Malpaso Mill, located just 36 kilometres from the Cusi Property.
Vat Construction
Two additional leach vats are under construction at the Corporation's Malpaso mill and a fifth is planned. Vats #3 and #4 will be completed during mid-April and will then be loaded with mill tailings for leach processing. These two additional vats will raise the leach capacity to an average of 200 tonnes per day. The fifth vat is scheduled to be operational during mid-May.
The Corporation has concluded a smelting and purchase agreement with Penoles and during March shipped eight dore bars totaling 114.4 kilos; the total silver content will be reported on completion of smelting and refining.

Hallo,
eine Frage zum "rights offering"
Meine Bank direktanlage.at teilt mir mit, dass dieses offering restricted ist für einige provinzen kanadas und die USA.
Ich krieg also nix...
Sie hätten auch bei der Lagerstelle urgiert, aber dort wäre auch auf die Restriktion verwiesen worden.
Ich hab das schon öfter durchgezogen, so was hab ich noch nicht gehabt.
Bei EXN war´s ein bisserl schwierig bei den in D gekauften shares.
hat aber auch geklappt.
Was ich nicht glaube.
Habt ihr eine Nachricht bekommen etc.
Jedenfalls hab ich Dia bras auch angeschrieben.

Antwort auf Beitrag Nr.: 39.448.589 von Tschonko am 03.05.10 22:32:55Hallo Tschonko,
ich kenne es so, daß man als ausländischer Anteilseigner nur in den seltensten Fällen an solchen Aktionen teilhaben kann.
Mache mir aber ehrlich gesagt auch keinen Kopf darum. Ein rights offering könnte mich nur interessieren, wenn ich sowieso mit dem Gedanken spielen würde, in Dia Bras mehr zu investieren. Das tue ich aber nicht.
Das mit der unbeantworteten Mail - tja, da habe ich mich auch schon bei verschiedensten Firmen drüber aufgeregt. Einige sind da vorbildlich, die meisten Antworten Dir nie. Eigentlich sollte man die Konsequenzen daraus ziehen. Aber was interessiert es einen gestressten Geologen in Mexiko, ob hier einer ein paar tausend shares abstößt. Den letzten beißen die Hunde, und das sind i.d.R wir Kleinanleger.

danke mal.
Ich hab das überhaupt noch nie erlebt.
Mit dem übernommenen boltz hatt ich auch mailcontact.
Ansonsten immer ziemlich schnelle Antwort.
Wie gesagt, ich kannte bisher nur eine Restriction und die auch nur vom lesen, bei pinnacle.
Und bei EXN war die Frage, ob die shares Lagerstelle in D bedient würden.
Wurden sie.
Unwichtig wär´s nicht dabei zu sein, weil man die dilution etwas auffängt.
Außerdem hab ich vorher, eh auch zu 0,17 aufgestockt, dass es eine schöne runde zahl wird.
Hab DIB ja über Exmin angedient bekommen.
Drum bin ich so sauer.
Wenn die nicht antworten, wird halt die Bank die Rechte verscherbeln.
Zahlen gab´s übrigens auch noch: gar nicht so schlecht.
Hat sich jedenfalls was getan.
Nur Zinc copper Durchlauf auf Malpaso war deutlich geringer...

Dia Bras Plans Major Geophysical Surveys at its Bolivar Property
MONTREAL, QUEBEC, May 04, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) (the Company) is pleased to report that it has contracted Quantec International Project Services Ltd. (QIPS) to conduct Induced Polarization (IP) geophysical surveys on its 21,552 hectare Bolivar Property (Figure 1 below) in Chihuahua, Mexico. The IP surveys will examine two areas http://www.diabras.com/en/newscenter/2010/map.pdf and have two major objectives:
La Cascada Gold Prospect
The objective at the La Cascada is to detect and map potential high chargeability and resistivity zones that could be related to gold mineralization discovered by previous surface sampling. These geophysical characteristics are typical of a high-sulphidation gold system, and anomalies detected by the survey will be immediate drill targets. The survey is oriented over zones that contain up to 7 g/t gold in highly silicified outcrops. Five lines of 1.2 km each will be surveyed, for a total of 6 line-km.
Bolivar Mine and Environs
The objective at the Bolivar Mine area is to detect and map high-chargeability and low-resistivity zones that may be related to skarn mineralization at and near the Banda Fault. High-grade skarn mineralization at Bolivar is consistently associated with high chalcopyrite contents, which range up to 20-25% in the higher-grade mineralized bodies. The geologic concept behind the design of the survey in this area is that mineralizing fluids moving along the Banda Fault could have formed large skarn or replacement deposits where the highly receptive Upper and Lower Skarn carbonate beds are cut by the fault. Any chargeable body detected by the survey will be an immediate drill target. Nine lines of 1.5 km each will be surveyed, for a total of 13.5 line-km.
The Survey
The survey will utilize a Titan-24 IP Survey, which is a proprietary, multi-channel, multi-parameter, Distributed Acquisition System (DAS), that records D.C. Resistivity and Induced Polarization data. It uses a large, multi-channel, fixed receiver array in combination with a wide variety of possible current injection arrays and highly accurate 24-bit sampling to achieve great depth of penetration, data quality and detectibility. First used in mineral exploration applications in 2000, the Titan-24 IP Survey has been applied to exploration for a wide variety of commodies, including gold, copper, base metals, diamonds, and more. In addition to its field acquisition system, the Titan-24 IP is complemented by its full-waveform, digital signal processing platform and its 2D-3D forward modeling and inversion capability.
The Titan 24 IP Survey planned for the Bolivar Project will enable Dia Bras to detect anomalies potentially related to mineralization and proximal alteration at depths of up to 500 metres. The survey is planned for June-July. Line cutting is in progress and construction of a road to the La Cascada target area will begin after permits have been obtained.

Dia Bras Drills More High-Grade Copper-Zinc Mineralization at Bolivar
MONTREAL, QUEBEC, May 06, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) (Dia Bras or the Company) is pleased to announce more results of drilling at its Bolivar Mine, which is being conducted in support of pilot-mining with the mineralized rock produced being shipped to the Company's Malpaso Mill. Dia Bras intends to continue mining rock of 10-12% combined copper-zinc until the Company's new mill at Bolivar is operational, at which time production will shift to a lower combined grade of copper-zinc. These new drill holes demonstrate Dia Bras's continued ability to discover new areas of high-grade mineralization at the Bolivar Mine.
Guadalupe Area
The latest drill holes have penetrated mineralization similar to that of the Titanic, Selena, Rosario, etc. bodies that hosted high-grade mineralization and have provided a sustainable flow of production to the company. So far, Dia Bras has followed these trends of high-grade mineralization for over 400 m along general NNW-SSE trends (Fernandez and Breccia Linda trends). The Fernandez trend, when projected an additional 400 m to the SSE, encounters the Increible breccia pipe where the Corporation is initiating mining of copper-rich mineralization.
Surface drill hole DB10B320 intercepted 1.9 metres of high-grade zinc mineralization (see Table 1 below) that is similar to mineralization encountered in surface drill holes DB09B316 (6.7 m @ 1.5% Cu & 11.25% Zn; please see Dia Bras news release of March 2, 2010) and DB10B321 (assays pending). These intercepts are about 50 m SE of the present workings of the Guadalupe body (see attached Guadalupe long section http://www.diabras.com/en/newscenter/2010/Guadalupe_seccion_… ) and are probably related to the same mineralized trend. Development of this new zone is in progress.
The 400 m gap between the southeastern limit of the drilled portion of the Fernandez trend and the Increible breccia pipe is expected by Dia Bras' geologists to host several more high-grade bodies of mineralization and is a prime target for exploration during 2010. The Quantec deep-sensing electrical survey planned for June-July will cover this highly-prospective area as part of the planned survey areas (please see Dia Bras news release of May 4, 2010).
San Angel Trend
Exploration and development drifting in the San Angel Trend area, combined with underground drilling, continues to discover areas of high-grade copper and zinc mineralization. Three underground drill holes (see Table 1 below) have penetrated high grades of copper and zinc immediately adjacent to the current operating drift (see attached San Angel long section http://www.diabras.com/en/newscenter/2010/San_Angel_Seccion.… This mineralized zone contains higher grades of copper than the Guadalupe area, with grades as high as 28% copper as chalcopyrite.

MONTREAL, QUEBEC, May 06, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) (Dia Bras or the Company) is pleased to announce more results of drilling at its Bolivar Mine, which is being conducted in support of pilot-mining with the mineralized rock produced being shipped to the Company's Malpaso Mill. Dia Bras intends to continue mining rock of 10-12% combined copper-zinc until the Company's new mill at Bolivar is operational, at which time production will shift to a lower combined grade of copper-zinc. These new drill holes demonstrate Dia Bras's continued ability to discover new areas of high-grade mineralization at the Bolivar Mine.
Guadalupe Area
The latest drill holes have penetrated mineralization similar to that of the Titanic, Selena, Rosario, etc. bodies that hosted high-grade mineralization and have provided a sustainable flow of production to the company. So far, Dia Bras has followed these trends of high-grade mineralization for over 400 m along general NNW-SSE trends (Fernandez and Breccia Linda trends). The Fernandez trend, when projected an additional 400 m to the SSE, encounters the Increible breccia pipe where the Corporation is initiating mining of copper-rich mineralization.
Surface drill hole DB10B320 intercepted 1.9 metres of high-grade zinc mineralization (see Table 1 below) that is similar to mineralization encountered in surface drill holes DB09B316 (6.7 m @ 1.5% Cu & 11.25% Zn; please see Dia Bras news release of March 2, 2010) and DB10B321 (assays pending). These intercepts are about 50 m SE of the present workings of the Guadalupe body (see attached Guadalupe long section http://www.diabras.com/en/newscenter/2010/Guadalupe_seccion_… ) and are probably related to the same mineralized trend. Development of this new zone is in progress.
The 400 m gap between the southeastern limit of the drilled portion of the Fernandez trend and the Increible breccia pipe is expected by Dia Bras' geologists to host several more high-grade bodies of mineralization and is a prime target for exploration during 2010. The Quantec deep-sensing electrical survey planned for June-July will cover this highly-prospective area as part of the planned survey areas (please see Dia Bras news release of May 4, 2010).

Gold-sampling auf Cusi:
Dia Bras Confirms High Gold Grades at the Minerva Vein of its Cusi Property
MONTREAL, QUEBEC, May 10, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to announce results of underground sampling of the Minerva vein, which is part of the Promontorio mine area of Dia Bras' Cusi property in Chihuahua State, Mexico. Gold grades up to 32 g/t occur in the sampled drift. Earlier surface sampling of the Minerva vein returned grades up to 5.5 g/t gold (see press release of November 15, 2007), and these new results confirm that the Minerva vein is a gold-rich vein. The vein also exhibits geochemical characteristics of veins in the Promontorio area compared to the Santa Eduwiges area, wherein Promontorio samples are generally much lower in base metals (0.00X-0.0X %) whereas Santa Eduwiges samples are higher (0.X-X.0%). These data indicate that the Promontorio veins are higher in the precious metals system than those at Santa Eduwiges, which is also consistent with the higher gold values in the Promontorio area.
"These results are very encouraging for us," stated Daniel Tellechea, President and CEO of Dia Bras. "As we develop the Promontorio veins for pilot-mining during 2011, we can forecast a higher gold production than we previously considered, in addition to our silver production."
Samples were collected in the drift at the 2085 m elevation of the Minerva vein (see Minerva Underground Sampling long section http://www.diabras.com/en/newscenter/2010/Minerva.pdf). Little is known of the history of the Minerva workings, only that development of a shallow shaft and some drifting were done, possibly 20-30 years ago or perhaps even earlier.
Dia Bras intends to conduct additional mapping and sampling of the Minerva vein and its immediate area. This work will be followed by surface diamond drilling as part of the long-range development and pilot-mining of the Promontorio project.

Dia Bras Confirms High-Grade Mineralization at San Patricio Property
MONTREAL, QUEBEC, May 11, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) (Dia Bras or the Company) is pleased to announce results of sampling from the San Patricio target, which is one of several targets at the Bacerac project. The Bacerac project consists of 48,500 hectares located in northeastern Sonora State near the border with Chihuahua State, Mexico, and was acquired with the EXMIN business combination.
"The San Patricio target is one of the first targets acquired from EXMIN to be advanced to the drill stage," stated Daniel Tellechea, President and CEO of Dia Bras. "Our target is an open-pitable deposit of considerable size. We expect more drill targets to be generated on the EXMIN properties this year, which will bring more advanced projects into our pipeline of projects, thereby increasing the chances of success."
Dia Bras has commenced an exploration program at the Bacerac concession in order to evaluate its mineral occurrences and to bring the San Patricio target to the drilling stage. The San Patricio target area consists of a 400 m by 600 m area of alteration and mineralization surrounding a series of small mine workings. The San Patricio mine, in the center of the mineralized area (see attached map http://www.diabras.com/en/newscenter/2010/SanPatricio.pdf), consists of a small working developed on a brecciated structure striking northeast. Sampling across the structure of the mine by EXMIN yielded high metal grades, including an interval of 9.5 metres with weighted averages of 4.95 g/t Au, 2,128 g/t Ag, 3.9 % Cu, and greater than 10.9 % Pb (samples 6123-6126). See EXMIN news release of December 11th, 2007.
Confirmation sampling by Dia Bras over an interval of 8.3 m during the present exploration program yielded weighted averages of 2.28 g/t Au, 1,722 g/t Ag, 1.0% Cu, and 6.0% Pb (samples 11017-11019). Systematic sampling along a grid has identified an area measuring about 100 metres in a northwesterly direction around the San Patricio mine; further sampling is in progress to further define the size of the mineralized zone (see sample locations on attached map).
The project area contains Tertiary volcanic rocks consisting of rhyolitic and andesitic flows and breccias that overlie probable Cretaceous sedimentary rocks; both units locally exhibit strong alteration. Mineralization is commonly associated with strongly silicified rhyolitic rocks near the base of the unit at or near the contact with underlying sedimentary rocks. Veins are locally important. There are multiple small mines and prospects in the region.
San Patricio contains a small mine worked informally by "gambusinos" in the past. Sampling has yielded gold, silver and base metal values in a relatively flat-lying tabular breccia or manto formed at the base of rhyolitic volcanic rocks where they overlie limestone. This mineralized body contains quartz and calcite in abundant veins with no preferred orientation (stockwork breccia) as well as in breccia cement.
A large area of alteration and mineralization surrounds the San Patricio mine area and provides a large exploration target. The area is poorly exposed and is partly covered by soil.

Highlights
Q1 2010 Highlights
1. The Company shows positive net working capital, including cash, of $4.9
million at March 31, 2010 and $2.8 million at December 31, 2009,
compared with a negative net working capital of $5.6 at March 31, 2009,
showing a positive change of $10.5 million for the twelve months ended
March 31, 2010.
2. The Company had Adjusted EBITDA(1) of $1.736 million for the three
months ended March 31, 2010 and of $1.944 million for the year ended
December 31, 2009, compared with ($1.187) million for the three months
ended March 31, 2009.
3. Operating cash costs(2) were US$83.92 per metric tonne milled in the
first quarter of 2010 as compared to US$66.85 for the first quarter of
2009 and US$91.10 during the year ended December 31, 2009 for the
Bolivar pilot-mining activities, amounting to a 25.5% increase from the
first quarter of 2009. This increase in operating cash costs from the
first quarter of 2009 is mostly due to the change in the exchange rate
for the Mexican peso to US dollar (11.0%) and to the general inflation
from 2009 to 2010 (4.9%), as the tonnage milled in each of these two
quarters was very similar.
4. Bolivar Mine sales were $5,956,000 for the first quarter of 2010, up
2.4% compared with $5,813,000 in the fourth quarter of 2009, and
compared with net sales of $17,037,000 for the year ended December 31,
2009. The increase from the fourth quarter of 2009 is primarily due to
an increase in average sales prices net of a 14% lower copper grade.
5. During the three months ended March 31, 2010, copper production
decreased 5.4% compared to 2009. This decrease was mainly due to lower
head grades. In the first quarter of 2010, zinc production increased by
4.3% over the same period of 2009 mainly due to an increase in head
grades to the mill.
6. By the end of the first quarter of 2010, the Company had installed a new
electric line to the plant site, commenced site clearing for the plant,
started the search for process equipment to be purchased, completed
engineering studies for the new facilities to be constructed and
initiated the work for the eventual water supply for the Bolivar Mill. .

(earnings before interest expense, taxes, and depreciation and
amortization) is adjusted for stock-based compensation expense and
nonrecurring items.
(2) "Operating Cash Costs" is a non-GAAP measure defined as the costs of
mining, transport to the mill and milling divided by the tonnes
milled.

Dia Bras Reports Significant Copper-Zinc Mineralization Near its New Mill Site
MONTREAL, QUEBEC, Jul 14, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to report that a broad area of copper-zinc mineralized skarn, known as "Los Americanos North", is located only one kilometre from its new Piedras Verdes Mill site, which is under construction and scheduled for commissioning in early 2011. By road, the area is only three kilometres from the mill site.
"This is an exciting development for Dia Bras because it significantly expands the area where we can discover and develop mineable deposits that will provide feed for our new mill," stated Daniel Tellechea, President & CEO. "As we continue exploration outside the immediate area of the Bolivar Mine, we are finding more and more locations that have the potential to become new mines."
Sampling and mapping by the Company's geologists has defined two areas of skarn-altered andesite, the largest of which is a 1,000 x 200-300 m area with potentially-economic copper-zinc mineralization. Another area to the north is believed to be less eroded and therefore has less exposure of mineralized rock (see attached location map: http://www.diabras.com/en/newscenter/2010/Americanos-Flat_Sa… This setting is identical to that at the Bolivar Mine where metasediments underlying andesite host high-grade copper-zinc mineralization. The metasediments underlying the Los Americanos andesite are considered to be high-priority drill targets. This area will be drilled as part of the Company's continuing regional exploration program.
Mapping and sampling to the south along this skarn trend (Los Americanos South) is continuing, focused on similar mineralization that has been discovered in that area, which indicates significant potential for expansion of the Los Americanos trend of copper-zinc mineralization.
The table below shows the results of selected samples from the two areas (see attached sample location map: http://www.diabras.com/en/newscenter/2010/Americanos-Locatio…

Dia Bras Accelerates Advanced Development at CUSI
MONTREAL, QUEBEC, Jul 15, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to report that advanced development at its Cusi silver project is being accelerated, with expanded drilling at the Promontorio mine and new drilling at the San Juan mine leading to mine planning. Both mines are being prepared for pilot-mining during early 2011 and drilling continues to yield high grades of silver from them. Production from the Santa Eduwiges mine is increasing month-by-month.
"These results are very encouraging," states Daniel Tellechea, President and CEO of Dia Bras. "We expect to mine from three mines simultaneously next year and therefore increase the amount of rock processed at our Malpaso Mill, which is only 36 km by good road from these mines. The high grades of silver encountered in each mine area indicate that our potential silver production over the next few years will increase significantly, especially when the other mines in the property are developed and mining commences."
Locations of drill holes reported here are for the Promontorio (http://www.diabras.com/en/newscenter/2010/PR-julio-El_Gallo_… , Santa Eduwiges (http://www.diabras.com/en/newscenter/2010/PR-julio-San_Anton… , and San Juan (http://www.diabras.com/en/newscenter/2010/PR-julio-San_Juan_… areas.

Dia Bras Drills More High Grade Silver at Cusi
MONTREAL, QUEBEC, Aug 4, 2010 (Marketwire via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTUREIB) is pleased to report that drilling in support of mine planning at its Cusi silver project is returning significant results, with more high-grade intercepts from the Promontorio, Santa Eduwiges and San Juan mines, plus elevated gold grades from San Juan. Both the Promontorio and San Juan mines are being prepared for pilot-mining during early 2011.
"These results are very encouraging but not surprising", states Daniel Tellechea, President and CEO of Dia Bras. "We have constantly drilled high silver grades at this project and the presence of gold at San Juan is especially encouraging."
Locations of drill holes reported here are shown in http://www.diabras.com/en/newscenter/2010/El%20Gallo_DDH_2au… Figure 1 of the Promontorio Area (El Gallo Vein) and http://www.diabras.com/en/newscenter/2010/San%20Antonio_DDH_… Figure 2 of the Santa Eduwiges Area (San Antonio Vein).

Dia Bras Announces Proposed Consolidation of Outstanding Common Shares and Increase in Maximum Number of Shares Reserved Under Stock Option Plan
MONTREAL, QUEBEC, Aug 16, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. ("Dia Bras") (the "Company") (TSX VENTURE: DIB) announces that it will be seeking approval by its shareholders of a special resolution authorizing the consolidation of all of the Company's issued and outstanding common shares (each, a "Common Share") on the basis of a ratio of not more than one (1) post-consolidation Common Share for a maximum of seven (7) pre-consolidation Common Shares (the "Consolidation"), with the Consolidation to be implemented by the Board of Directors of the Company (the "Board") at any time prior to December 31, 2010.
The shareholders will be asked to approve the proposed Consolidation at a special meeting of the shareholders to be held in Montreal, Quebec, on September 14, 2010. The proposed Consolidation remains subject to receipt of all necessary regulatory approvals, including shareholder approval and acceptance of TSX Venture Exchange.
Upon completion of the proposed Consolidation at the maximum authorized ratio of 1:7, the number of Common Shares issued and outstanding would be reduced from 491,438,086 as of August 9, 2010, to 70,205,440.
The Company believes that the number of the currently outstanding Common Shares may no longer reflect the value of the assets of the Company. The Company's future performance is largely tied to the Company's ability to raise equity financings, without excessively diluting the interests of its current shareholders. The proposed Consolidation will enable potential investors to better evaluate the Company in connection with future equity financings of the Company. The proposed Ratio will help Directors to mitigate potential dilution, depending on the circumstances under which the Consolidation is implemented.
The Consolidation should also allow institutional shareholders to hold Dia Bras shares in their portfolios and to reduce the trading execution costs for shareholders.
If the proposed Consolidation is approved by the shareholders, it will be implemented only upon a determination by the Board that the Consolidation is in the best interests of the Company and its shareholders at that time. The name of the Company will not be changed following the Consolidation.
Stock Option Plan
The Company also announces that the Board has approved, subject to regulatory approvals, an increase in the number of Common Shares reserved under the Company's fixed number stock option plan (the "Plan") from 13,600,000 to 21,600,000. The number of Common Shares reserved under the Plan represents 4.4% of the total number of Common Shares currently issued and outstanding.
Resignation of Director
Mr. Robert Hirsh has resigned from the Board of Directors of Dia Bras to pursue other interests. The Board would like to thank Robert for his many years of dedicated service to Dia Bras and wishes him success in his pursuits

Dia Bras Development Drift Reaches El Gallo Deposit at the Bolivar Property
MONTREAL, QUEBEC, Aug 23, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) is pleased to report that its 240-m-long underground development drift has reached the El Gallo deposit at the Bolivar Property in Chihuahua State, Mexico. Development towards this deposit began from the San Francisco zone of the Bolivar Mine, which is to the northwest of El Gallo.
The El Gallo deposit is not part of the Bolivar Mine. It is distinctly different in mineralogy, metal content and mineralization style. Development of the copper-mineralized zone at the southwestern end of the El Gallo deposit in preparation for mining has begun, with ramps being driven above and below the deposit.
"This is an exciting development for us, which shows the great exploration potential of El Gallo and the ability of our staff to keep discovering and providing significant high-grade material to our Malpaso Mill," stated Daniel Tellechea, President & CEO. "Production from this future new mine, El Gallo, together with production from the Bolivar Mine, is planned to reach 1,000 tonnes per day by the time our new Piedras Verdes Mill is commissioned. Our production costs will be almost halved with the new mill's operation, and we are proceeding rapidly to develop the mineralized areas that will provide feed to the new mill."
The El Gallo zone is a 550 m long by 40-150 m wide area that contains significant copper mineralization in a skarn zone of the Bolivar mineralized system. Seven drill holes plus continuous channel sampling at 2-metre-intervals along the side panels of the El Gallo 3 adit provide the control for the section shown in Figure 1 http://www.diabras.com/en/newscenter/2010/elgallo_seccion_n6… It is important to note that this zone is open down dip and that exploration and development in that direction is expected to increase the mineralized volume significantly.
Figure 1 shows a longitudinal section from the western cliffs of El Gallo to the El Gallo 3 adit driven into the skarn horizon. Table 1 below shows the true thicknesses and grades of copper mineralization along this section. Steep topography prevents complete infill drilling of the horizon, but cliff exposures indicate the zone is continuous over the 500 m length shown in the longitudinal section. The average true thickness is 13.6 m, and with an average width of 80 m and a length of 500 m, the mineralized volume is 544,000 cubic metres.

Dia Bras Renegotiates Reyna de Oro Option Agreement at Bolivar Property
MONTREAL, QUEBEC, Sep 20, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) ("Dia Bras") (the "Company") is pleased to report that it has renegotiated the terms of the purchase option agreement for the remaining 75% interest of the Reyna de Oro mine concessions it does not already own. The reduced payment schedule will save the Company approximately US$600,000.
"The Reyna de Oro deposit was previously drilled by EXMIN," stated Daniel Tellechea, President & CEO of Dia Bras, "and the results indicate that significant gold mineralization is present. Our geologists believe that the old mine is one of numerous potential gold deposits that occur along a more than 5 kilometre northeast trend of strong gold occurrences on the western side of our wholly-owned Bolivar Property. We recently initiated a drill program at another gold target, La Cascada, located approximately 5 kilometres northeast of the Reyna de Oro mine."
The New Terms
The Company owns a 25% interest in the two concessions included in the Reyna de Oro option agreement. During July and August, 2010, the Company renegotiated the option agreement for the acquisition of the 75% interest it does not own and entered into a purchase agreement to acquire the remaining rights for $381,816 (US$360,000), payable in four installments of $95,454 (US$90,000). The first installment was paid with the signing of the purchase agreement, and the second is to be paid in December 2010, the third in March 2011 and the last in June 2011. This project also includes certain concessions owned 100% by the Company, including the over 14,000 hectare Luz de Oro concession.
Increasing Gold Trend at Bolivar Property
At the Reyna de Oro mine, EXMIN Resources Inc. ("EXMIN") completed 2,200 metres of drilling at the project, and delineated a nearly flat lying tabular body averaging about 20 to 30 metres in thickness with 2-4 g/t gold and locally significant copper. The body is open along strike and down dip and locally contains significantly higher grades, including drill intercepts of 18 m of 6 g/t Au, 11 m of 7 g/t Au, and 3 m of 25 g/t Au. See Table 1 below for the selected intercepts from EXMIN's 2004 and 2005 drill campaigns at the Reyna de Oro mine.

The 14,936 hectare Reyna de Oro Project was EXMIN's first project and is adjacent to Dia Bras' 6,684 hectare Bolivar Project. The wholly-owned, combined land package is now the 21,620 hectare Bolivar Property that also hosts the Bolivar Mine and other base metals deposits and is located in a very well mineralized region with several current mining and exploration projects, including Goldcorp's El Sauzal mine.
Exploration around the Reyna de Oro mine indicates that mineralization may be related to a large intrusion located 2 km east of the mine. Also, several factors indicate that there is potential for the discovery of blind skarn mineralization similar to that encountered in the surrounding region (http://www.diabras.com/en/newscenter/2010/map15septiembre201… see Regional Mineralized Trends map). The project also hosts several other targets, including La Cascada and La Sidra to the north, and Balojaque, located 7 km south of the Reyna de Oro mine, which consists of several quartz veins with as much as 105 g/t gold.
La Cascada Gold Target
The La Cascada mineralization has characteristics similar to several multi-million ounce high-sulfidation gold deposits, such as the gold association with structurally controlled vuggy silica zones, the style of alteration zonation, association with copper and arsenic, presence of pyrophyllite, etc. La Cascada is notably similar to the El Sauzal deposit, which is located less than 20 km to the southeast and is on the same regional, NNW-trending major structural zone. La Cascada is near the Company's existing infrastructure, only 2 km south of its Cieneguita camp, and lies within the prolific Sierra Madre Occidental gold-silver belt of northwestern Mexico that hosts several multi-million ounce gold deposits.
Three Induced Polarization-Resistivity survey lines (http://www.diabras.com/en/newscenter/2010/LaCascada_Titan24_… were completed in this area of rugged terrain: a 1,000-m-long N-S line and two E-W lines (800 and 900 m), which resulted in detection of three significant anomalies - all of which are associated with anomalous grades of gold in outcrop, as evidenced by the results of 2-metre-width, chip-channel sampling. The southernmost anomaly on the N-S line starts at 50 m depth. Sampling of outcrops over an area of 50 x 85 m was conducted prior to the survey and the six samples assayed 0.6 - 1.1 g/t gold.
Sampling in the area of the central anomaly (also starting at 50 m depth), conducted over a 40 x 50 m area (again prior to the survey), resulted in the eight samples assaying 0.5 - 2.1 g/t gold.
Sampling in the area of the northernmost anomaly, conducted over a 10 x 20 m area (also prior to the survey), resulted in the three samples assaying 0.4 - 3.0 g/t gold.
The truncation of the chargeability anomalies at an apparent constant 50 m depth is inferred to be the result of oxidation of the high-sulfide zones, remnants of which appear on the surface as 1-2% pyrite and abundant jarosite, hematite and goethite.
The surveyed area is only about 10% of the area known to host strong gold anomalies, with samples assaying up to 15 g/t gold

Dia Bras Renegotiates Reyna de Oro Option Agreement at Bolivar Property
MONTREAL, QUEBEC, Sep 20, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) ("Dia Bras") (the "Company") is pleased to report that it has renegotiated the terms of the purchase option agreement for the remaining 75% interest of the Reyna de Oro mine concessions it does not already own. The reduced payment schedule will save the Company approximately US$600,000.
"The Reyna de Oro deposit was previously drilled by EXMIN," stated Daniel Tellechea, President & CEO of Dia Bras, "and the results indicate that significant gold mineralization is present. Our geologists believe that the old mine is one of numerous potential gold deposits that occur along a more than 5 kilometre northeast trend of strong gold occurrences on the western side of our wholly-owned Bolivar Property. We recently initiated a drill program at another gold target, La Cascada, located approximately 5 kilometres northeast of the Reyna de Oro mine."
The New Terms
The Company owns a 25% interest in the two concessions included in the Reyna de Oro option agreement. During July and August, 2010, the Company renegotiated the option agreement for the acquisition of the 75% interest it does not own and entered into a purchase agreement to acquire the remaining rights for $381,816 (US$360,000), payable in four installments of $95,454 (US$90,000). The first installment was paid with the signing of the purchase agreement, and the second is to be paid in December 2010, the third in March 2011 and the last in June 2011. This project also includes certain concessions owned 100% by the Company, including the over 14,000 hectare Luz de Oro concession.
Increasing Gold Trend at Bolivar Property
At the Reyna de Oro mine, EXMIN Resources Inc. ("EXMIN") completed 2,200 metres of drilling at the project, and delineated a nearly flat lying tabular body averaging about 20 to 30 metres in thickness with 2-4 g/t gold and locally significant copper.

Dia Bras Intercepts Wide Silver-Lead-Zinc-Copper Mineralization in First Diamond Drill Hole at its Melchor Ocampo Property in Zacatecas State, Mexico
MONTREAL, QUEBEC, Oct 26, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) ("Dia Bras") (the "Company") is pleased to report that it has received assay results from the first diamond drill hole of its current drilling program at the Las Coloradas project in the Melchor Ocampo mineral district, Zacatecas State. The hole intercepted 119.6 m of skarnified limestone and averages 65.6 g/t (2 ounces) silver, 1.16% lead, 1.43% zinc and 0.11% copper.
"This is an exciting result for a first drill hole in a property that is approximately 20 km north of the world-class Penasquito mine, which is also a precious metal orebody with base metal by-products," stated Daniel Tellechea, President & CEO. "Our target at Las Coloradas is a large-tonnage, underground-mineable silver deposit with important zinc-lead-copper by-product credits, and this first hole of our program has confirmed that such mineralization exists over a very wide interval. As we continue the evaluation and exploration of the properties acquired in the EXMIN transaction, our portfolio of attractive properties keeps increasing."
The Las Coloradas project is located in the Melchor Ocampo mineral district, which is known for the occurrence of large carbonate replacement deposits of precious and base metals. Las Coloradas is approximately 20 kilometres due north of Goldcorp's Penasquito mine, as well as near important mines/projects in Zacatecas such as Aranzazu (Aura Minerals), Tayahua (Frisco) and Camino Rojo (Goldcorp) (http://diabras.com/files/media/58564_Melchor%20Ocampo%20Dist… see attached map).
The first Las Coloradas drill hole, Drill Hole DLC10B001, was drilled on a bearing of 180 degrees and at an inclination of -45 degrees to twin a hole drilled by Echo Bay Minerals in 1996, hole Z96-35, that was lost in mineralization at 246 m. That hole returned 69.0 metres of core averaging 51 g/t silver, 1.2% lead and 1.1% zinc. The results from Dia Bras' first drill hole are shown in Table 1.

Dia Bras Doubles Capacity Planned for its New Mill at the Bolivar Property and Provides Update on Construction Progress
MONTREAL, QUEBEC, Nov 02, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) (the "Company") is pleased to report that construction of its new Piedras Verdes Mill at the Bolivar Property in Chihuahua, Mexico, is progressing on time and on budget for commissioning early in the second quarter of 2011. Of particular note is that due to its exploration and development results, the Company has seized the opportunity to purchase larger ball mills at essentially the same price as the smaller mills included in the original budget. The new mill has a design capacity of 1,000 tpd rather than the earlier-announced 500 tpd. Capex for the new mill remains unchanged at US$ 12.1 million.
"This increase in capacity of our new mill is an important step forward for Dia Bras", stated Daniel Tellechea, President and CEO. "Our operational staff has searched diligently for the best value-for-price as we purchased components for the mill. The results of our exploration activities, which have utilized state-of-the-art geophysical surveys followed by drilling and underground development, mean that a larger mill is required. This doubling of capacity will have a very positive effect on our production, yet is accomplished for basically the same capital expenditure. The construction of the Piedras Verdes Mill at the Bolivar Property is an important milestone for the Bolivar mining district, because Dia Bras has been in pilot-mining mode since 2005, transporting high-grade copper-zinc-silver rock for 270 kilometres to be processed at its Malpaso Mill. The reduction in transportation costs and increased capacity should add value to Dia Bras and significantly increase its mine development potential."
The new Piedras Verdes Mill will process mineralized rock mined from the Bolivar Mine, La Increible mine and El Gallo mine. The latter two mines are being developed so that they will begin operations at the same time the Piedras Verdes Mill is commissioned.
Several aspects of the construction are notable:
- The Piedras Verdes Mill is being constructed by Dia Bras' 100%-owned Mexican subsidiary, EXMIN, S.A. de C.V.
- The milling site has been terraced and leveled in preparation for installation of two Dominion 9'6" x 14' ball mills. These were acquired at about the same price as two ball mills that would have given the mill a capacity of only 500 tpd. They provide the milling capacity necessary to expand the mill further to a capacity of 2,000 tpd.
- The site for the fine ore bins has been terraced and leveled, and is 90% complete. http://www.diabras.com/files/media/ce38a_PV%20Mill%20-%20Ore… Terraced site for the fine ore bins
- Flotation cells, pumps, motors, agitator mechanisms, etc. necessary for the initial 1,000 tpd operation have been acquired. http://www.diabras.com/files/media/9ce48_PV%20Mill%20-%20Flo… Flotation cells
- The foundations have been completed for the copper and zinc concentrate thickeners and storage facilities, and construction of these is underway. http://www.diabras.com/files/media/439b8_PV%20Mill%20-%20Con… View of concentrates patios (foreground) with zinc and copper thickener tanks in background
- The crushing and screening site has been terraced and leveled. The following equipment has been acquired for this site: a Cedar Rapids 25" X 40" jaw crusher, a Sandvick 6800 cone crusher, and a Terex Simplicity 6' X 16' double-deck screen.http://www.diabras.com/files/media/9f158_PV%20Mill%20-%20Ced… Cedar Rapids 25" X 40" jaw crusher http://www.diabras.com/files/media/10c35_PV%20Mill%20-%20San… Sandvick 6800 cone crusher
- The tailings dam is being prepared and construction of the dam itself will begin at the beginning of 2011.
- Construction of the water reservoir, located only two kilometres from the mill site and with a design capacity of 1.5 million m(3), is well underway and is expected to be completed in early 2011. http://www.diabras.com/files/media/90245_PV%20Dam%20Construc… Piedras Verdes Water Reservoir under construction
- Electrical power lines have been connected to the regional power grid and provide 34,000 volts, which is necessary for this phase of construction.
- Retaining walls covering 2,160 m(3) have been constructed along the site's access roads.
- An ore stockpile pad covering 500 m(3) has been completed.
- The construction crew totals 125 personnel, of which 12 are supervision and administration, and another 12 are support personnel such as cooks, cleaners, etc. An important aspect of this crew is that 95% of them are local residents, most living within 20 km of the mill site. The mill construction has given a significant boost to employment of the local residents.

MONTREAL, QUEBEC, Nov 02, 2010 (MARKETWIRE via COMTEX News Network) --
Dia Bras Exploration Inc. (TSX VENTURE: DIB) (the "Company") is pleased to report that construction of its new Piedras Verdes Mill at the Bolivar Property in Chihuahua, Mexico, is progressing on time and on budget for commissioning early in the second quarter of 2011. Of particular note is that due to its exploration and development results, the Company has seized the opportunity to purchase larger ball mills at essentially the same price as the smaller mills included in the original budget. The new mill has a design capacity of 1,000 tpd rather than the earlier-announced 500 tpd. Capex for the new mill remains unchanged at US$ 12.1 million.
"This increase in capacity of our new mill is an important step forward for Dia Bras", stated Daniel Tellechea, President and CEO. "Our operational staff has searched diligently for the best value-for-price as we purchased components for the mill. The results of our exploration activities, which have utilized state-of-the-art geophysical surveys followed by drilling and underground development, mean that a larger mill is required. This doubling of capacity will have a very positive effect on our production, yet is accomplished for basically the same capital expenditure. The construction of the Piedras Verdes Mill at the Bolivar Property is an important milestone for the Bolivar mining district, because Dia Bras has been in pilot-mining mode since 2005, transporting high-grade copper-zinc-silver rock for 270 kilometres to be processed at its Malpaso Mill. The reduction in transportation costs and increased capacity should add value to Dia Bras and significantly increase its mine development potential."
The new Piedras Verdes Mill will process mineralized rock mined from the Bolivar Mine, La Increible mine and El Gallo mine. The latter two mines are being developed so that they will begin operations at the same time the Piedras Verdes Mill is commissioned.
Several aspects of the construction are notable:
- The Piedras Verdes Mill is being constructed by Dia Bras' 100%-owned Mexican subsidiary, EXMIN, S.A. de C.V.
- The milling site has been terraced and leveled in preparation for installation of two Dominion 9'6" x 14' ball mills. These were acquired at about the same price as two ball mills that would have given the mill a capacity of only 500 tpd. They provide the milling capacity necessary to expand the mill further to a capacity of 2,000 tpd.
- The site for the fine ore bins has been terraced and leveled, and is 90% complete. http://www.diabras.com/files/media/ce38a_PV%20Mill%20-%20Ore… Terraced site for the fine ore bins
- Flotation cells, pumps, motors, agitator mechanisms, etc. necessary for the initial 1,000 tpd operation have been acquired. http://www.diabras.com/files/media/9ce48_PV%20Mill%20-%20Flo… Flotation cells
- The foundations have been completed for the copper and zinc concentrate thickeners and storage facilities, and construction of these is underway. http://www.diabras.com/files/media/439b8_PV%20Mill%20-%20Con… View of concentrates patios (foreground) with zinc and copper thickener tanks in background
- The crushing and screening site has been terraced and leveled. The following equipment has been acquired for this site: a Cedar Rapids 25" X 40" jaw crusher, a Sandvick 6800 cone crusher, and a Terex Simplicity 6' X 16' double-deck screen.http://www.diabras.com/files/media/9f158_PV%20Mill%20-%20Ced… Cedar Rapids 25" X 40" jaw crusher http://www.diabras.com/files/media/10c35_PV%20Mill%20-%20San… Sandvick 6800 cone crusher
- The tailings dam is being prepared and construction of the dam itself will begin at the beginning of 2011.
- Construction of the water reservoir, located only two kilometres from the mill site and with a design capacity of 1.5 million m(3), is well underway and is expected to be completed in early 2011. http://www.diabras.com/files/media/90245_PV%20Dam%20Construc… Piedras Verdes Water Reservoir under construction
- Electrical power lines have been connected to the regional power grid and provide 34,000 volts, which is necessary for this phase of construction.
- Retaining walls covering 2,160 m(3) have been constructed along the site's access roads.
- An ore stockpile pad covering 500 m(3) has been completed.
- The construction crew totals 125 personnel, of which 12 are supervision and administration, and another 12 are support personnel such as cooks, cleaners, etc. An important aspect of this crew is that 95% of them are local residents, most living within 20 km of the mill site.
