Aktueller Exploration-Bericht hört sich sehr vielversprechend an.
TORONTO, ONTARIO--(CCNMatthews - Oct. 13, 2004) - Tsodilo Resources Limited (TSX Venture Exchange: TSD) is pleased to announce the commencement of a drilling program in Botswana and to provide the following update on its exploration activities and plans for the Company`s current Ngamiland diamond exploration program.
There are three main thrusts to the drilling program:
- Kimberlite A37 - further evaluation
- Explore high-priority, identified kimberlite targets
- Explore a satellite image feature that may reflect the location of an interpreted alluvial paleochannel
A37 Kimberlite
Vertical Reverse circulation drilling of this target commenced on October 8, 2004. The first hole, 37-7, intersected an upward-fining sequence of crater facies kimberlitic sediments underlying sandy overburden of the Kalahari Formation at 41 meters. This crater sequence is dominated by fragments of fine-grained macrocryst-bearing kimberlite with a relatively low country-rock xenolith content (approximately 10 to 15 %) in the depth interval 81-90 meters, and extends to a depth of 105m after which the drill hole intersected a zone dominated by dolomite and phyllite. The hole was terminated at 116 meters in this bedrock.
Drill target A37-8 was also tested with a vertical reverse circulation drill hole. Beneath a 42 meter thickness of Kalahari sediment and calcretes, the hole intersected an upward fining sedimentary sequence, with a thick basal coarse fragmental unit, carrying subrounded to angular wallrock fragments, grading upwards into coarse sandstones and overlying shales and muds, typical of the sequences that characterize crater lake infill. Country rock dolomite and phyllite form the floor to this sequence at a depth of 152 meters. The hole was terminated at 156 meters in this bedrock on October 13, 2004.
The Company achieved its objective of obtaining coarser-grained samples with a higher probability of carrying micro-diamonds than previous drillhole samples from the A37 body.
Drill cuttings from these two holes will be sent to Mineral-Logic in Cape Town, South Africa, for integrated petrographic and indicator-mineral analysis and if warranted to the Saskatchewan Research Council for micro-diamond analysis and interpretation. The results will be released on completion of the processing.
Our initial estimate of the size of the A37 kimberlite crater is some 1 000m in length by 500m to 600m in width with a strong probability of an extension to the east of this - we conservatively estimate the kimberlite and crater sediments to extend over a 115 hectare surface area. In total 8 holes (6 previously) have now been drilled at A37 for a total of 1,010 meters. While further drilling will be required to delineate this body with greater accuracy, our interpretation of the results suggest that A37 would be the second or third largest kimberlite discovered in the Republic of Botswana to date. The Republic of Botswana is the largest producer of diamonds, by value, in the world.
High Priority Identified Targets
Eight drillholes are planned to investigate associated magnetic, gravity and kimberlitic indicator mineral (KIMs) anomalies within the known Nxau Nxau cluster.
The drilling program will also include several targets outside of the Nxau Nxau cluster; one in the Gcwihaba licences where a sodium-rich eclogitic (diamond inclusion) garnet was found in a loam sample over an airborne magnetic anomaly; and, one hole into each of three G9 peridotitic kimberlitic garnet anomalies over magnetic features in the Guma area (three out of four of these results were fully reported in our press release dated Wednesday, August 4, 2004). These latter four targets are currently the subject of detailed gravity and magnetic surveys to further define the drill targets. Kimberlitic ilmenites and garnets were also recovered in the Guma area as a result of a 5 x 5 kilometer regional grid sampling campaign and previous direct sampling over target magnetic anomalies.
There are 48 loam samples currently being analysed for indicator minerals and these results should be reported within two weeks. Any additional indicator mineral anomalies from these samples will also be investigated by detailed gravity and magnetic surveys before drilling sites are selected.
Satellite image feature - possible paleochannels
Tsodilo recently acquired high resolution satellite radar and false-colour imagery to obtain evidence for the location and distribution of pre-Kalahari-aged alluvial channels. These can be viewed on our website www.tsodiloresources.com, in the "Imagery" section. One of our primary motivations for exploring the Newdico and Gcwihaba licence areas is the fact that macro-diamonds and G10 garnets occur in secondary alluvial deposits of the Kalahari basin at Tsumkwe and Omatako in Namibia. The location and distribution of the paleochannels that transported these secondary alluvial deposits will allow us to follow the trail of indicator minerals back to their primary source, which we believe lies within our licence areas.
The Consultant commissioned to perform the gravity survey along the border has completed his initial line of survey along a 30km portion of the border. This line straddles a prominent linear satellite image feature (see, the area indicated on the satellite imagery as Border gravity points). The gravity survey shows that this image feature is coincident with a major gravity low (between stations 200 and 460m - see the gravity profile below), which the geophysical consultant interprets to reflect a major pre-Kalahari valley. A further gravity low (between stations 0 - 100) has been interpreted to reflect a second channel to the south. After completion of drilling on the targets in the Nxau Nxau area, we will begin to drill in these features to determine the actual presence of these paleochannels and any associated alluvial sediments. If these sediments offer encouragement, we will commence further gravity traverses across the interpreted course of these paleochannels, and continue to follow-up with drilling to confirm their location and whether the associated alluvial sediments carry kimberlite indicator minerals.

Tsodilo Resources Limited-Kimberlite Confirmed at A15-Program Update
16:00 EDT Monday, October 25, 2004
TORONTO, ONTARIO--(CCNMatthews - Oct. 25, 2004) - Tsodilo Resources Limited ("Tsodilo") (TSX Venture Exchange:TSD) is pleased to announce the discovery of a new kimberlite on its Newdico (Pty) Limited license block in Botswana.
A15
Drill target A15 is a coincident magnetic and gravity anomaly with an indicated diameter of approximately 800 - 1,000 meters. The magnetic anomaly is dipolar and roughly circular, indicative of a pipe-like intrusive body. (See, geophysical gravity and magnetic images on the Company`s website under Images - Geophysical) The target was tested with a vertical reverse circulation drill hole. After drilling through loose sand and a thick section of silcrete (Kalahari formation), numerous coarse kimberlitic ilmenites and pyrope garnets of up to 5 mm in size were visually identified in weathered kimberlite from 34 meters depth.
Drilling commenced on October 22nd, 2004 and ceased on October 25, 2004. Due to technical problems of drilling with a high groundwater inflow, the drillhole was stopped at 116m depth still in primary kimberlite. The primary kimberlite appears to be a tuffisitic kimberlite breccia (TKB) but is highly weathered throughout the section drilled. The weathered TKB contains xenoliths of basement shales, quartzite, granite and basalt throughout the section.
Target A15 is located approximately 25km east of the Namibia / Botswana border in the Company`s Newdico license block. The kimberlite lies within the Nxau Nxau kimberlite field where 22 kimberlites have been identified to date. Target A15 lies approximately 1.5 km from a kimberlite body (anomaly 40/97/07, drillhole THC 16) discovered by the Ashton / Reunion joint venture in February of 1998. This kimberlite tested positive for micro-diamonds but was determined to be uneconomic. Previous geochemical loam sampling work over A15 resulted in the collection of numerous picro-ilmenites and a lesser amount of kimberlitic garnet grains.
Drill cuttings will be sent to Mineral-Logic in Cape Town, South Africa, for integrated petrographic and indicator-mineral analysis and if warranted to the Saskatchewan Research Council for micro-diamond analysis and interpretation. The results will be released on completion of the processing.
1821-15C and A33
Targets 1821-15C and A33 were drilled from October 18th - 21st. No kimberlite or crater facies sediments were intersected in the holes. Previous soil sampling had recovered kimberlitic indicator minerals over these targets and both detailed gravity and magnetic surveys indicated a possible kimberlite source. The anomalies remain unexplained and further assessment of the data will be done before further drilling is performed.
SOIL SAMPLING
On October 21, 2004, the Company received the final report on the results of the recent kimberlite indicator mineral loam sampling program. The results will be reviewed and entered into the Company`s GIS data base, after the current drill program is completed, in order to analyze and evaluate the results and determine whether further work or an extension of the program is warranted. Loam sampling is one of the many tools that the Company utilizes in selecting targets to perform detailed ground geophysics and in the selection of additional targets to be drill tested.
Due to the upcoming Presidential election in the Republic of Botswana, work will cease until November 2, 2004 to give the drilling crew time off to participate in the country`s democratic process. Drilling will resume on the Namibian / Botswana border when work recommences.
Tsodilo Resources is an international diamond exploration company engaged in the search for economic kimberlites at its Newdico and Gcwihaba projects in northwest Botswana. The Republic of Botswana is the largest producer of diamonds, by value, in the world. Tsodilo has a 75% stake in Newdico while Trans Hex Group, a South African diamond mining and marketing company, holds the remaining 25%.

Hi hjfab,
zur Zeit erfordert meine kleine PET (Petrel Resouces) meine volle Aufmerksamkeit, aber danach widme ich mich Tsodilo!
Hat jemand eine Idee, wann wieder mit News zu rechnen ist? Gibts schon Ergebnisse zu den im Oktober gestarteten Untersuchungen, von denen in den älteren Posters die Rede ist?

hi hennm,
die letzte inhaltliche Meldung stammt vom 8.12.2004:
am Bohrloch 16 wurde eine positive Kimberliteindikation entdeckt. Mit Bohrloch 15 (Meldung vom 26.10.) schaut es nicht so schlecht aus. Die Proben liegen jetzt in Kapstadt:

Kimberlite Confirmed at A16, Program Update
--------------------------------------------------------------------------------
TORONTO, ONTARIO - December 8, 2004 - Tsodilo Resources Limited ("Tsodilo") (TSX Venture Exchange: TSD) is pleased to announce the discovery of a new kimberlite on its Newdico (Pty) Limited license block in Botswana.
A16
Drill target A16 is a coincident magnetic and gravity anomaly with an indicated diameter of approximately 800 - 1,000 meters. The magnetic anomaly is dipolar and roughly circular, indicative of a pipe-like intrusive body. (See, geophysical gravity and magnetic images on the Company`s website under Images - Geophysical) The target was tested with a vertical reverse circulation drill hole. After drilling through loose sand to 25 meter depth (Kalahari Formation), a sequence of limestone breccias mixed with vein quartz and biotite rich shales was intersected to the end of the hole depth of 143 meters. Although no kimberlite was intersected, the breccias have been identified in the field as altered kimberlite crater material similar to that intercepted in kimberlite intrusives A12 and A37 previously discovered by the Company.
Drilling commenced on November 24th, 2004 and ceased on November 28th. Due to technical problems of drilling with a high groundwater inflow, the drill hole was stopped at 143m depth still in crater facies The interception of kimberlitic crater material at this depth indicates that the pipe is well preserved.
Target A16 is located approximately 20km east of the Namibia / Botswana border in the Company`s Newdico license block. The kimberlite lies within the Nxau Nxau kimberlite field where 23 kimberlites have been identified to date. Target A16 lies approximately 1.5 km from a kimberlite intrusive (anomaly 40/97/07, drillhole THC 16) discovered by the Ashton / Reunion joint venture in February of 1998. This kimberlite tested positive for micro-diamonds. Previous geochemical loam sampling work over A16 resulted in the collection of numerous picro-ilmenites.
Drill cuttings will be sent to Mineral-Logic in Cape Town, South Africa, for integrated petrographic and indicator-mineral analysis and if warranted to the Saskatchewan Research Council for micro-diamond analysis and interpretation. The results will be released on completion of the processing.
A15
On October 25, 2004 the Company announced the discovery of this kimberlite intrusive. Photos of kimberlite indicator minerals recovered as a result of the drill program have been posted to the Company`s website (See, Image Gallery - A15 - Kimberlite Indicator Minerals (KIMs)). These and other specimens recovered have been submitted for electron microprobe analysis. The results will be released on completion of the processing.
In den letzten 3 Tagen ist in Kanada der Kurs wieder von 1,50 auf 1,90 zurückgekommen. Allerdings unter geringen Umsätzen. Geht seit dem Absturz (denke das waren Gewinnmitnahmen) seitwärts unter wenig Umsätzen und Schwankungen zwischen 2,0 und 1,5.
Ich bin zwar kein Bergbauexperte, aber es sollte nicht so schlecht aussehen, oder ????

es geht sehr schön weiter, wenn man die letzten
Stunden betrachtet. Der Kurs ist ja ganz schön
explodiert
denke, das war noch nicht das letzte Wort. Die
Aktie war ja in Deutschland unterbewertet, wenn
man Kanada betrachtet, die liegen auf 1,90, das sind
1,14 Euronen, wenn ich mich nicht verrechnet habe.

Alles noch ruhig hier?
Also, wenn man von explodieren spricht, muss man auch immmer mal auf den Umsatz schauen. Und der ist mehr als dünn. Wenn dann von einer (zugegeben großen) Order der Kurs nach oben springt, ist leider nix dahinter.
Also machen wir uns nichts vor, Tsodilo ist wie ein Lottoschein mit etwas mehr Gewinnchancen als bei 6aus49. Nur die Ausschüttung ist bezogen auf den Einsatz dafür auch nicht so groß (1000% ?)
Wenn die was finden - Rauf.
Wenn die bis Ende 2005 nix finden - 123runter, 123weg.
Finden die was?
Wer weiß!

In Botswana ist übrigens Regenzeit. Da kommt man kaum mit einem Allrad, geschweige denn mit Bohrtechnik durch. Vor März/April geht da nix!
Hi Folks!

Exploration Program Update & Preliminary Microprobe Results of the A15 Kimberlite
--------------------------------------------------------------------------------
TORONTO, ONTARIO - Tsodilo Resources Limited ("Tsodilo") (TSX Venture Exchange: TSD) is pleased to announce the results of their 2004 exploration campaign, their conclusions and planned exploration for 2005 in both their Gcwihaba (Pty) Ltd and Newdico (Pty) Limited license blocks in Botswana.
Nxau Nxau Kimberlite Field
Gravity and magnetic grid surveys were performed over six selected airborne magnetic anomalies within the Nxau Nxau kimberlite field to better define the geophysical interpretation and model the suspected kimberlite intrusives. The 1 km x 1 km. grids were orientated N-S with line spacing of 250m and 50m station spacing. Airborne anomalies 1821C12, A15, A16, A41, 1821C15 and 1821C9 were surveyed and used in a prioritization exercise together with the loam sampling results to direct the drilling campaign.
The October and November 2004 drilling campaign in the Nxau Nxau field evaluated five of the high-priority targets where all the above evidence suggested the presence of kimberlitic intrusive rocks. A further two drill holes were directed at obtaining further samples from the known A37 kimberlite, to sample coarser crater sediments and/or kimberlite with the objective of reaching a decision as to the probability of achieving a positive micro-diamond result. The results of this drill campaign are summarized in Table 1 below.
It should be noted that the A15 kimberlite is very different from the other 23 kimberlite intrusives intersected to date in the Nxau Nxau field. The lack of crater sediments and deep weathering suggests that the upper portion of the kimberlite has been eroded off and that we are intersecting the base of the crater with several kimberlite lapilli identified in the petrographic examination. This may indicate an older kimberlite intrusive event. Furthermore, the abundance of garnet and chrome diopside grains in the drill cuttings contrasts with the preponderance of ilmenite found in the other kimberlites. The A15 kimberlite is, therefore, older and compositionally different from the other 23 kimberlites investigated in the cluster to date.
A sample of the picked garnet, chrome diopside and ilmenite grains recovered from A15 were photographed and posted to the Company`s website on December 8, 2004 (See, Image Gallery - A15 - Kimberlite Indicator Minerals (KIMs)). As background, there are two broad groups of garnet in kimberlite - the peridotitic and eclogitic suites. A subset of compositions from both suites can occur as inclusions in diamonds, and the presence of either or both subsets provides strong encouragement that the kimberlite has sampled the diamond stability field. Peridotite garnet (G9 and G10), tends to vary in color from red to purple (G9 compositions) to lilac (G10 garnet). The G10 garnet grains are the diamond inclusion compositions for the peridotitic suite and are characterized by Ca-poor, Cr-rich compositions relative to the G9 peridotitic garnet. The presence of G10 garnet thus provides good evidence that the kimberlite has sampled the diamond stability field. Eclogitic garnet tends to have yellow to orange colors. Diamond inclusion eclogitic garnet is Ti-poor, but has relatively high Na2O (>0.7% Na2O).
A sample split of garnet, chrome diopside and ilmenite grains were submitted to the Euclid Geometrics Laboratory ("Euclid or Euclid`s") in Canada for electron microprobe analysis. Utilizing proprietary methods of microprobe mineral analysis, the lab was able to achieve accuracy to within 1%.
Preliminary and partial results from Euclid`s study are:
G10 and G9 garnet, along with eclogitic garnet from the diamond stability field, were identified from the sample submitted using electron microprobe analysis.
For the A15 pyropes, the element trends readily distinguish garnet from four types of rock: 1) a high-grade metamorphic rock that did not equilibrate with Cr-rich kimberlite magma; 2) a compositionally homogeneous megacrystic rock with low Cr (0.0-0.1 Cr apfu), possibly eclogite; 3) a peridotite affected by Al-1Cr (0.08-0.33 Cr apfu), with minor Mg-1Fe at constant Ca indicating reaction with olivine; and 4) another peridotite affected by Al-1Cr (0.13-0.41 Cr apfu), with major Mg-1Ca at constant Fe indicating an influx of carbonate melt and transport.
The pyrope garnet chemistry indicates derivation from a number of rock types and the compositional trends indicate a changing compositional and pressure environment. Diamond and graphite are only stable in a reduced environment, indicated in the A15 samples by Fe2+ >> Fe3+ and by low concentrations of H. The pyrope has a reduced crystal chemistry, with Fe2+ >> Fe3+, Ti3+ >> Ti4+, and minor X-site Cr2+, indicating an environment favorable to diamond formation and preservation.
The reduced crystal chemistry of the chrome diopside grains is consistent with garnet from this location and indicates stability with reduced carbon and a positive preservation potential for diamond.
The A15 diopside grains exhibit enrichment in Na due to a high-pressure jadeite substitution. This substitution is rare in diopside from kimberlite, but is found at other diamond-rich kimberlite deposits and indicates a Na-rich rock subjected to very high pressure. For a 40mW/m2 regional geotherm, the range of pressure is from 750 0C at 31 kbar (110 km) to 1200 0C at 64 kbar (210 km). The majority of diopside grains probed plot in the diamond stability field.
Euclid`s analyses of the ilmenite grains from A15 reflect a distinct reducing environment that is conducive to good diamond preservation.
"This is only a preliminary finding on a statistically small sample of indicator grains, but there is sufficient encouragement in the results to conclude that further drilling and sampling of A15 is warranted with the aim of sending a representative sample of this kimberlite to the Saskatchewan Research Council Laboratories for micro-diamond analysis. We have made arrangements to begin drilling on A15 in the first week of May in order to obtain better volume and quality samples for analysis" commented James M. Bruchs, President & CEO.
A further press release will be issued once the complete report from the Euclid Geometrics Laboratory has been received.
Border Gravity Survey and Drill Program
The gravity traverse surveyed along a 30 km portion of the Namibian border straddles a prominent linear satellite image feature (See under "Images" on the Company website the area indicated on the satellite imagery as Border gravity points). The gravity results were interpreted by the geophysical consultant as possibly reflecting two pre-Kalahari paleochannels. A series of 19 shallow drill holes along this border section indicated that this interpretation was incorrect and that there was no sign of any alluvial sediment in the Kalahari section or any paleochannel erosion of the basement rocks. We conclude that the late-Cretaceous aged (90 Mybp) drainage(s) that deposited kimberlite indicator minerals and diamonds into the Etosha basin at Tsumkwe, some 40 km west of the border, has subsequently been eroded by scarp retreat of the much younger Miocene-aged (5 Mybp) easterly flowing streams that drained into the Okavango-Makgadigadi basin.
Drilling is planned across the eastern end of the satellite feature in order to intersect the younger Miocene-aged alluvial sediment in the Kalahari below the recent aeolian cover in order to pick up the trail of indicator minerals that may lead to the primary source of the Tsumkwe G10 garnets and macro-diamonds.
Guma District Anomalies
The geophysical contractors completed ground gravity and magnetic surveys over three selected airborne magnetic anomalies in the Guma District where further singleton G9 lherzolitic garnet grains were recovered from loam sampling during 2004. Although the Company planned to drill these targets during the 2004 campaign, various delays resulted in postponement and drill testing of the Guma anomalies will be an early priority in the 2005 program, scheduled to start in early May.
In total, 10 singleton ilmenite and 11 singleton G9 garnet grains have been recovered from sampling within the roughly 40 km x 40 km block which comprises the Guma field. The geophysical contractors are currently busy with an additional four ground magnetic and gravity grids in this field. Once that is complete, targets will be selected for drill testing.
Regional Airborne Magnetic Surveys
A geophysical consultant has been commissioned to assist with the complete revision and priority rating of airborne magnetic targets in the light of the 2004 drilling results, particularly that of A15. In addition to this, the Company is determining the most appropriate and cost effective method of airborne surveying across the dyke swarm zone where the high amplitude response of the dolerite dykes masks any subtle magnetic anomalies, characteristic of kimberlitic intrusive rocks. Consultations with various geophysical contractors to perform the very low altitude and close line spacing survey required to define these subtle magnetic signatures within the "noisy" dyke swarm zone is advanced and a decision will be reached in the near future.
Gcwihaba License Area
Drilling on target 2021 B4, a co-incident gravity, ground magnetic and loam sampling anomaly (a single diamond inclusion eclogitic garnet) intersected magnetite quartzite below 158 meters of Kalahari cover. This result explains the magnetic anomaly but fails to explain the singleton diamond inclusion eclogitic garnet.
The Company intends, as a lower priority, to perform further drilling at this target and at the other targets in the northern Gcwihaba ground for which ground gravity and magnetic surveys have already been performed.

A sample of the picked garnet, chrome diopside and ilmenite grains recovered from A15 were photographed and posted to the Company`s website on December 8, 2004 (See, Image Gallery - A15 - Kimberlite Indicator Minerals (KIMs)). As background, there are two broad groups of garnet in kimberlite - the peridotitic and eclogitic suites. A subset of compositions from both suites can occur as inclusions in diamonds, and the presence of either or both subsets provides strong encouragement that the kimberlite has sampled the diamond stability field. Peridotite garnet (G9 and G10), tends to vary in color from red to purple (G9 compositions) to lilac (G10 garnet). The G10 garnet grains are the diamond inclusion compositions for the peridotitic suite and are characterized by Ca-poor, Cr-rich compositions relative to the G9 peridotitic garnet. The presence of G10 garnet thus provides good evidence that the kimberlite has sampled the diamond stability field. Eclogitic garnet tends to have yellow to orange colors. Diamond inclusion eclogitic garnet is Ti-poor, but has relatively high Na2O (>0.7% Na2O).
A sample split of garnet, chrome diopside and ilmenite grains were submitted to the Euclid Geometrics Laboratory ("Euclid or Euclid`s") in Canada for electron microprobe analysis. Utilizing proprietary methods of microprobe mineral analysis, the lab was able to achieve accuracy to within 1%.
Preliminary and partial results from Euclid`s study are:
G10 and G9 garnet, along with eclogitic garnet from the diamond stability field, were identified from the sample submitted using electron microprobe analysis.
For the A15 pyropes, the element trends readily distinguish garnet from four types of rock: 1) a high-grade metamorphic rock that did not equilibrate with Cr-rich kimberlite magma; 2) a compositionally homogeneous megacrystic rock with low Cr (0.0-0.1 Cr apfu), possibly eclogite; 3) a peridotite affected by Al-1Cr (0.08-0.33 Cr apfu), with minor Mg-1Fe at constant Ca indicating reaction with olivine; and 4) another peridotite affected by Al-1Cr (0.13-0.41 Cr apfu), with major Mg-1Ca at constant Fe indicating an influx of carbonate melt and transport.
The pyrope garnet chemistry indicates derivation from a number of rock types and the compositional trends indicate a changing compositional and pressure environment. Diamond and graphite are only stable in a reduced environment, indicated in the A15 samples by Fe2+ >> Fe3+ and by low concentrations of H. The pyrope has a reduced crystal chemistry, with Fe2+ >> Fe3+, Ti3+ >> Ti4+, and minor X-site Cr2+, indicating an environment favorable to diamond formation and preservation.
The reduced crystal chemistry of the chrome diopside grains is consistent with garnet from this location and indicates stability with reduced carbon and a positive preservation potential for diamond.
The A15 diopside grains exhibit enrichment in Na due to a high-pressure jadeite substitution. This substitution is rare in diopside from kimberlite, but is found at other diamond-rich kimberlite deposits and indicates a Na-rich rock subjected to very high pressure. For a 40mW/m2 regional geotherm, the range of pressure is from 750 0C at 31 kbar (110 km) to 1200 0C at 64 kbar (210 km). The majority of diopside grains probed plot in the diamond stability field.
Euclid`s analyses of the ilmenite grains from A15 reflect a distinct reducing environment that is conducive to good diamond preservation.
"This is only a preliminary finding on a statistically small sample of indicator grains, but there is sufficient encouragement in the results to conclude that further drilling and sampling of A15 is warranted with the aim of sending a representative sample of this kimberlite to the Saskatchewan Research Council Laboratories for micro-diamond analysis. We have made arrangements to begin drilling on A15 in the first week of May in order to obtain better volume and quality samples for analysis" commented James M. Bruchs, President & CEO.
A further press release will be issued once the complete report from the Euclid Geometrics Laboratory has been received.
Border Gravity Survey and Drill Program
The gravity traverse surveyed along a 30 km portion of the Namibian border straddles a prominent linear satellite image feature (See under "Images" on the Company website the area indicated on the satellite imagery as Border gravity points). The gravity results were interpreted by the geophysical consultant as possibly reflecting two pre-Kalahari paleochannels. A series of 19 shallow drill holes along this border section indicated that this interpretation was incorrect and that there was no sign of any alluvial sediment in the Kalahari section or any paleochannel erosion of the basement rocks. We conclude that the late-Cretaceous aged (90 Mybp) drainage(s) that deposited kimberlite indicator minerals and diamonds into the Etosha basin at Tsumkwe, some 40 km west of the border, has subsequently been eroded by scarp retreat of the much younger Miocene-aged (5 Mybp) easterly flowing streams that drained into the Okavango-Makgadigadi basin.
Drilling is planned across the eastern end of the satellite feature in order to intersect the younger Miocene-aged alluvial sediment in the Kalahari below the recent aeolian cover in order to pick up the trail of indicator minerals that may lead to the primary source of the Tsumkwe G10 garnets and macro-diamonds.
Guma District Anomalies
The geophysical contractors completed ground gravity and magnetic surveys over three selected airborne magnetic anomalies in the Guma District where further singleton G9 lherzolitic garnet grains were recovered from loam sampling during 2004. Although the Company planned to drill these targets during the 2004 campaign, various delays resulted in postponement and drill testing of the Guma anomalies will be an early priority in the 2005 program, scheduled to start in early May.
In total, 10 singleton ilmenite and 11 singleton G9 garnet grains have been recovered from sampling within the roughly 40 km x 40 km block which comprises the Guma field. The geophysical contractors are currently busy with an additional four ground magnetic and gravity grids in this field. Once that is complete, targets will be selected for drill testing.
Regional Airborne Magnetic Surveys
A geophysical consultant has been commissioned to assist with the complete revision and priority rating of airborne magnetic targets in the light of the 2004 drilling results, particularly that of A15. In addition to this, the Company is determining the most appropriate and cost effective method of airborne surveying across the dyke swarm zone where the high amplitude response of the dolerite dykes masks any subtle magnetic anomalies, characteristic of kimberlitic intrusive rocks. Consultations with various geophysical contractors to perform the very low altitude and close line spacing survey required to define these subtle magnetic signatures within the "noisy" dyke swarm zone is advanced and a decision will be reached in the near future.
Gcwihaba License Area
Drilling on target 2021 B4, a co-incident gravity, ground magnetic and loam sampling anomaly (a single diamond inclusion eclogitic garnet) intersected magnetite quartzite below 158 meters of Kalahari cover. This result explains the magnetic anomaly but fails to explain the singleton diamond inclusion eclogitic garnet.
The Company intends, as a lower priority, to perform further drilling at this target and at the other targets in the northern Gcwihaba ground for which ground gravity and magnetic surveys have already been performed.

Kimberlite A15 Mineral Chemistry
--------------------------------------------------------------------------------
TORONTO, ONTARIO - Tsodilo Resources Limited ("Tsodilo") (TSX Venture Exchange: TSD) is pleased to announce the availability of a detailed report on the mineral chemistry of the drill samples from kimberlite A15 drilled in their Newdico (Pty) Limited license block in Botswana.
Background to the discovery of A15
Kimberlite A15 has a coincident magnetic and gravity anomaly with an indicated diameter of approximately 800 - 1,000 meters. The magnetic anomaly is dipolar and roughly circular, indicative of a pipe-like intrusive body. (See, geophysical gravity and magnetic images on the Company`s website under Images - Geophysical) The target was tested with a vertical reverse circulation drill hole in October 2004. After drilling through loose sand and a thick section of silcrete (Kalahari formation), numerous coarse kimberlitic ilmenites and pyrope garnets of up to 5 mm in size were visually identified in weathered kimberlite from 34 meters depth.
Due to technical problems of drilling with a high groundwater inflow, the drillhole was stopped at 116m depth still in primary kimberlite. The primary kimberlite appears to be a tuffisitic kimberlite breccia (TKB) but is highly weathered throughout the section drilled. The weathered TKB contains xenoliths of basement shales, quartzite, granite and basalt throughout the section.
Kimberlite A15 is located approximately 25km east of the Namibia / Botswana border in the Company`s Newdico license block. The kimberlite lies within the Nxau Nxau kimberlite field where 23 kimberlites have been identified to date. Kimberlite A15 lies approximately 1.5 km from a diamondiferous kimberlite body anomaly 40/97/07, drillhole THC 16) discovered in February of 1998. Previous geochemical loam sampling work over A15 resulted in the collection of numerous picro-ilmenites and a lesser amount of kimberlitic garnet grains.
Drill sample processing
Drill samples were sent to the Scientific Services laboratory for separation of the heavy minerals which were then picked by the Mineral Logic laboratory in order to identify and recover kimberlitic indicator minerals. After splitting of these grains to a representative fraction, 40 garnet grains, 12 chrome diopside grains and 50 ilmenite grains were mounted for electron microprobe analysis:- these are marked as the RC set. A second sample of indicator minerals separated on site by means of panning of drill cuttings was also sent to the Mineral Logic laboratory for further picking and splitting. This set of probe grains are marked as the PC set and consist of 106 garnet and 21 chrome diopside grains.
The probe mounts were dispatched to the Euclid Geometrics laboratory in Kitchener, Ontario, for microprobe analysis. The full set of results and the report of their Consultant Mineralogist are posted on our website at www.tsodiloresources.com/s/MineralChemistry.asp.
Summary Conclusions
The following conclusions were reached from consideration of the mineral chemistry:
The mineral chemistry of the ilmenite suite indicates a reduced environment with a good to excellent potential for diamond preservation, with low resorption.
The chemistry of the chrome diopside grains indicates that 58% fall into the diamond stability field. The composition of the A15 diopside is virtually identical to that of the Jericho (NWT, Canada) and the Grib (Arkhangelsk, Russia) kimberlite pipes, which are economically viable. In contrast to the typical diopside of kimberlite, these three kimberlites all exhibit a rare jadeite-kosmochlor substitution.
The composition of the A15 megacryst garnets is similar to the megacrystic suite of the diamond-rich Jericho kimberlite of the Slave craton with both exhibiting a distinct reduced crystal chemistry, which is most promising for the stability and preservation of diamond.
The A15 mineral compositions are comparable to those of the diamond-rich Jericho kimberlite, a (Na, Ca)-rich rock in which the diopside is jadeite-rich and the G10/G9 line separating peridotitic garnet-with-diamond from garnet-with-graphite is shifted towards Ca-rich compositions. This modified plot places 51% of the A15 peridotitic garnets in the diamond zone.
Eclogitic garnets were also identified from their chemical composition; 40% of these fall within the diamond inclusion field. As with Orapa and several other producing kimberlites, the potential diamond contribution from eclogites in the A15 kimberlite may be considerable.
These very encouraging results have led to a decision to drill further holes into the A15 kimberlite to obtain both a better distribution and a bigger volume of sample. These samples will be analysed for micro-diamonds as an estimator of the economic potential of this very promising kimberlite. Drilling will begin in mid-May.
President and CEO James Bruchs comments: "A15 clearly indicates that there is a very different type of kimberlite in the Nxau Nxau field. While it is too early to tell whether A15 or similar type kimberlites are the source of the Omatako or Tsumkwe secondary anomalies to the west of our license block, the G10 garnet ratio, as calculated by typical CaO vs Cr2O3 wt.% methods, of our most representative sample (RC) is comparable to those reported for Omatako and Tsumkwe ".

Zusammenfassende Zusammenfassungen Die folgenden Zusammenfassungen wurden von der Betrachtung der Mineralchemie erreicht: Die Mineralchemie der Ilmenitsuite zeigt ein verringertes Klima mit einem gutem ausgezeichnetem Potential für Diamantbewahrung, mit niedriger Aufnahme an. Die Chemie der Chrom diopside Körner zeigt an, daß der 58% Fall in die Diamantstabilität auffangen. Der Aufbau des diopside A15 ist zu dem des Jericho (NWT, Kanada) und der Grib (Arkhangelsk, Rußland) Kimberliterohre praktisch identisch, die ökonomisch entwicklungsfähig sind. Im Gegensatz zu dem typischen diopside von Kimberlite, stellen diese drei Kimberlites alle einen seltenen Jadeit-kosmochlor Ersatz aus. Der Aufbau der megacryst A15 Granate ist der megacrystic Suite des Diamant-reichen Jericho Kimberlite des Sklavencraton mit beiden ähnlich, die eine eindeutige verringerte Kristallchemie ausstellen, die für die Stabilität und die Bewahrung des Diamanten am vielversprechendsten ist. Der Mineralaufbau A15 ist mit denen des Diamant-reichen Jericho Kimberlite, a vergleichbar (Na, Ca)-reicher Felsen, in dem das diopside Jadeit-rich und die Linie G10/G9, die peridotitic Granat-mit-Diamanten vom Granat-mit-Graphit trennt ist, wird in Richtung zum CA-REICHEN Aufbau verschoben. Dieser geänderte Plot legt 51% der peridotitic Granate A15 in die Diamantzone. Eclogitic Granate wurden auch von ihrem chemischen Aufbau gekennzeichnet; 40% von diesen Fall innerhalb der Diamanteinbeziehung fangen auf. Wie mit Orapa und einigen anderen produzierenden Kimberlites, kann der mögliche Diamantbeitrag von den Eclogites im Kimberlite A15 beträchtlich sein. Diese sehr anregenresultate haben zu eine Entscheidung geführt, um weitere Bohrungen in den Kimberlite A15 zu bohren, um eine bessere Verteilung und ein grösseres Volumen der Probe zu erhalten. Diese Proben werden auf Mikro-Diamanten als Abschätzer des ökonomischen Potentials dieses sehr vielversprechenden Kimberlite analysiert. Die Bohrung fängt im MittlerMai an. Präsident und CEO James Bruchs Anmerkungen: "A15 zeigt offenbar an, daß es eine sehr andere Art Kimberlite im Nxau Nxau auffangen gibt. Während es zu früh ist zu erklären, ob A15 oder ähnliche Art Kimberlites die Quelle der Omatako oder Tsumkwe Sekundärabweichungen zu westlich von unserem Lizenzblock sind, ist das Verhältnis des Granats G10, wie durch typischen CaO gegen Cr2O3 wt.% Methoden, unserer Repräsentativprobe (RC) errechnet mit denen vergleichbar, die für Omatako und Tsumkwe "berichtet werden. Tsodilo Betriebsmittel ist eine internationale Diamanterforschungfirma, die an der Suche nach ökonomischen Kimberlites an seinen Newdico und Gcwihaba Projekten in Nordwestbotswana teilnimmt. Die Republik von Botswana ist der größte Produzent der Diamanten, durch Wert, in der Welt. Tsodilo hat eine 81% Stange in Newdico während Transport Hexagon-Gruppe, ein südafrikanischer Diamantbergbau und Marketing-Firma, Einflüsse das restliche 19%. Der südliche Gcwihaba Projektbereich ist 100% gehalten durch Tsodilo Tochtergcwihaba Betriebsmittel (Pty) begrenzt. Tsodilo handhat die Erforschung beider Lizenzbereiche. Das Design und die Führung des Erforschungprogramms der Firma ist die Verantwortlichkeit des Peter Wanderers, ein professioneller Geologe, der mit dem südafrikanischen Rat für natürliche wissenschaftliche Berufe registriert wird.

Sehe ich genauso! Tsodilo wird übrigens als einer der vielversprechendsten Explorer in Botswana gehandelt!

Genauso sieht der Kurs aus! ;-)))
Aber zum Glück, verschimmeln die Diamanten ja nicht da wo sie liegen oder auch nicht!
