Colossus Minerals Inc. Takes Another Step Ahead With the Completion of Its Phase I Drilling Program on Serra Pelada
Wednesday August 20, 11:03 am ET
TORONTO, ONTARIO--(Marketwire - Aug. 20, 2008) - Colossus Minerals Inc. ("Colossus") (TSX:CSI - News) is proud to announce a summary of activities on the Serra Pelada project in Brazil, a Colossus-COOMIGASP joint venture.
Serra Pelada Project (gold and PGE's):
Colossus has successfully completed its Phase I drilling program on Serra Pelada. 17 diamond drill holes were completed for 5129 metres of HQ coring. One other hole (SPD-009) was abandoned due to poor drilling conditions. Drilling was focused on the Central Mineralized Zone along 250m strike length down plunge and southwest of the historical Serra Pelada open pit. All completed drill holes intersected apparently mineralised material but SPD-003, SPD-005 and SPD-006 were off target.
One drill hole, SPD-017 tested the Western Zone of mineralisation just to the west of the historical pit. This is a separate target from the Central Mineralised Zone, with limited historical drilling.
Additionally, one PQ diamond hole (SPD-019) is nearing completion and another is planned to provide samples for initial metallurgical test work.
Some 2266 half-core samples from 16 holes, representing 2596 metres of Phase I drilling, have been submitted over the past five months to SGS Limited (Belo Horizonte) for fire assay for gold, platinum and palladium. Colossus anticipates receiving more assay results within the next 3 weeks.
Complete assay results from SGS Belo Horizonte have been announced for SPD-001, SPD-002 and SPD-004 (see news releases May 29 and June 11, 2008) and are summarised below:
- SPD-001 intersected 88.00 metres @ 5.80g/t gold, 6.11g/t platinum and
- SPD-002 intersected 46.72 metres @ 24.11g/t gold, 9.04g/t platinum and
14.65 metres @ 22.51g/t gold, 4.56g/t platinum and 5.01g/t palladium
- SPD-004 intersected 53.50 metres @ 5.35g/t gold, 2.51g/t platinum and
A contract has been let for 5000m of Phase II diamond drilling by two rigs to be commenced first week of October.
The first phase of Colossus' program of re-sampling and re-assaying a portion of the 40,000 metres of historical CVRD half-core has been completed. To date the results of screen fire and 50 gram fire assays for gold, palladium and platinum have been received for 605 samples, representing 623 metres of historic core. Two batches of these results, which have increased our confidence in CVRD's historical assay database and defined additional mineralization, have been released (see news releases April 01 and April 15, 2008). Check assaying for gold, platinum and palladium by Genalysis (Perth) is underway on several re-assay batches.
Genalysis is also undertaking assays of these materials for other PGE's (rhodium, etc.) for which there is limited historical data. Multi-element analysis is also being performed on a representative range of samples.
Colossus has continued its intensive community and joint venture partner relations programs, including support for COOMIGASP's evaluation of historical tailings and waste, environmental studies, and the provision of an ambulance for the Serra Pelada community.
Ari Sussman, CEO of Colossus, adds "The Colossus 2008 program represents a significant advance for Serra Pelada. Starting from scratch, our team has developed the facilities for handling major drilling and assay programs, executed these programs and laid the base for other advances toward mine development. On behalf of Colossus and COOMIGASP, I wish to thank the team for its continuing contribution."

"Toronto, Ontario, November 25, 2008 - Colossus Minerals Inc. (“Colossus”) (TSX:CSI) is pleased to announce that it has intersected further high grade gold-platinum-palladium in drilling of the Central Mineralised Zone of the Serra Pelada Project, the Colossus-COOMIGASP joint venture located in Para State, Brazil.
87.58 metres @ 6.04 g/t gold, 2.49 g/t platinum and 4.36 g/t palladium
including 24.70 metres @ 10.20 g/t gold, 7.15 g/t platinum and 12.99 g/t palladium
9.20 metres @ 13.97 g/t gold, 2.35 g/t platinum and 3.09 g/t palladium;
89.55 metres @ 2.48 g/t gold, 0.47 g/t platinum and 0.84 g/t palladium
including several intervals totalling more than 30 metres of +7 g/t gold + platinum + palladium ;
These drill holes, 25 metres to the southwest and northeast of previously announced drilling, demonstrate strong lateral and vertical continuity the Central Mineralised Zone.
Diamond drill holes SPD-010, SPD-011 and SPD-012 were HQ-cored for a total of 846 metres as part of the initial 5000m drill program by the Colossus-COOMIGASP joint venture on the Serra Pelada gold-platinum-palladium deposit, located in Para State, Brazil. Drilling was focused on the Central Mineralised Zone which overprints metasediments occupying the hinge and inner limbs of a NW-facing, SW-plunging, reclined synclinorium which plunges gently SW from the historical open pit. The Central Mineralised Zone is characterised by intense carbonaceous and also argillic alteration, inboard of siliceous alteration partially mantling the synclinorial hinge. See Sections 00 and 100NE plus a plane view of Serra Pelada drill traces under the Serra Pelada Project section at www.colossusminerals.com.
SPD-010, the first drill hole on Section 75NE, was drilled towards a similar structural position and in a similar orientation to SPD-001, 25 metres to the northeast. Like SPD-001 (88m @ 5.80 g/t gold, 6.12 g/t platinum and 6.83 g/t palladium) SPD-010 encountered a long interval of continuous gold-platinum-palladium mineralisation which includes a high gold + PGE subzone in the outer fold hinge. Assay results for SPD-010 are tabulated in the following table:
*Total assayed interval (>0.5 g/t gold equivalent) – excludes intervals of no core recovery; true widths to be established.
SPD-011, also collared on Section 75NE, mainly tested the north-western margin (inner hinge zone) of the Central Mineralised zone. Gold-platinum-palladium mineralisation proved to be essentially continuous through more than a 90 metre intersection, exhibiting substantial intervals of moderate grades. An additional drill hole is planned to establish grades between SPD-010 and SPD-011. Assay results for SPD-011 are tabulated in the following table:
SPD-012, on Section 50NE undercut SPD-004 (57.10m @ 5.02 g/t gold, 2.45 g/t platinum and 3.80 g/t palladium) and was designed to test outer hinge mineralisation. The hole was drilled too steeply and intersected mainly siliceous and argillic alteration with poor core recoveries, but with some significant mineralised intervals. Assay results for SPD-012 are tabulated in the following table:
Complete assay data sets for SPD-010, SPD-011 and SPD-012 may be examined under the Serra Pelada Project section on www.colossusminerals.com. Assay results for the remainder of Colossus Phase I drilling (SPD-013 to SPD-018) have now been received and will be released shortly, pending clarification of some assay quality issues.
Vic Wall, Colossus President, comments “Colossus’ drilling continues to demonstrate the continuity of high grade gold-platinum-palladium mineralisation in the Central Mineralised Zone at Serra Pelada. The results of these infill holes on previously sparsely drilled sections have clarified the distribution of a very high grade gold-PGE subzone. Phase II of our drilling program at Serra Pelada will bring the central part of the deposit to resource estimation stage.”
Sampling of SPD core (by Colossus personnel) and sample preparation (by SGS GEOSOL LABORATORIES LTDA., Belo Horizonte) were carried out under strict protocols recommended in the 43-101 Technical Report on Serra Pelada. After photographing and logging, nominal 1 metre intervals of HQ core were cut and/or split in half, yielding samples of 2 to 3 kilogram mass. Where core recoveries were low, intervals were composited to yield approximately 1 kilogram minimum sample masses. Duplicates, blanks and certified gold-PGE reference materials were inserted in the sample train by Colossus personnel prior to secure shipping to SGS.
SGS pulverised 1 kilogram splits (>95% passing 106 microns) from the crushed (>95% passing 1.7mm), dried samples. The resulting pulps were quartered by rotary splitter and a 50 gram fire assay, with ICP-OES finish was performed on one 250gm. aliquot, the remaining splits being archived. Additional blanks and duplicates were inserted in the assay stream by SGS and replicate assays were performed every twenty samples. SGS dispatched assay certificate originals directly to Resource and Exploration Mapping Ltd. an independent Company which manages Colossus’ database.
The SGS assay results for blanks, duplicates and replicates were generally satisfactory. However values obtained by SGS for certified Au-Pt-Pd reference materials were typically on the low side of mean multi-laboratory values but, in two (SPD-011) assay batches, were well below accepted ranges. A high grade gold reference material inserted by SGS also assayed unacceptably low in two (SPD-011) assay batches. SGS has not provided an explanation of these results. Reference materials and also high value samples from all batches will be check assayed by an independent laboratory.

Sehr interessanter Artikel, der Beste wie ich finde bis jetzt. Ist auf jeden Fall zu hoffen, daß sie Vale noch einiges von dem umliegendem Gebiet abknöpfen können, auch wenn die sich ja noch standhaft wehren(die Frage dürfte sein, welche Interessen sie damit verfolgen, bzw. welches Potenzial sie darin sehen(was wenn eigentlich keine PGE sein dürften)).
Ich werde in der Sache demnächst mal eine Anfrage an Colossus abschicken, oder hast Du da schon irgendwas genaueres z.B. über's Stockhouse rausbekommen?
Canaccord Adams: The worst for junior mining ‘is likely behind us'
Canaccord Adams metals analysts suggest that it may be time to accumulate small cap/mining exploration stocks that offer good value.
Author: Dorothy Kosich
Posted: Tuesday , 23 Dec 2008
RENO, NV -
Although the small-cap mining sector "has just been through its worst, most precipitous decline in modern history," metals analysts at Canaccord Adams say they believe "the worst is likely behind us."
Nevertheless, they noted a sustainable recovery in the junior mining sector will depend "upon the perception that an overall recovery in global demand for metals in imminent."
However, that turnaround will "likely depend on the efficacy of the government stimulus packages being implemented around the globe," they added.
"The year 2008 has shattered investor confidence, and market valuations reflect risk-averse investor sentiment," the analysts advised. "We believe that, to achieve a sustainable rally in the junior mining sector in 2009, investors must regain confidence in broader equity markets. "
"Given the ongoing issues in the global equity and credit markets, we believe that investors are likely to remain somewhat risk adverse. That said, opportunities to exist in the junior sector even under more subdued investor interest."
Canaccord Adams stressed that, in the current environment, investors should focus on companies with "balance sheet strength, above-average project portfolios and strong management sheets."
Junior mining companies with strong balance sheets "are more likely to survive prolonged sector weakness, which gives an investor an opportunity to benefit when the rebound in junior mining equities occurs," the analysts suggested.
In their report, the analysts outlined key mining sector drivers for 2009 including:
• Base metals prices: "The global outlook for metals demand remains grim." But low prices could be close to leveling off.
• Precious metals prices: "Credit concerns, a trend to further Fed easing...political tensions, diversification of central bank reserve holdings and the high US current account deficit all suggest a strain on the US dollar, and therefore strength in US-denominated bullion."
• Uranium: "We expect uranium to fare well through 2009 and beyond as the current global fleet of 439 plants is expanded by 39 plants under construction and as plans and proposal for an additional 379 plants are advanced; the price may be further enhanced as supply concerns arise."
• Diamonds: "This has been the least interesting sector in mining over the past five years in our view. ...With metal prices off, rumours suggest BHP and Rio Tinto are ramping up diamond exploration activities. In addition, advanced plays by Peregrine and Diamonds North could create renewed interest."
• US dollar: "As capital diversifies, will the U.S. dollar decline? If so it could be good for all metals."
• The TSX and Dow Jones: "If the US has been in recession since December 2007, we may have already seen the bottom of the market. If we are halfway through the recession we have good hopes for the markets in H2/09."
• The TSX Venture Index: While Canaccord Adams noted that the TSX-V has been down as much as 80% over the last 18 months, "We think the worst is over, but will the recovery be V-shaped or will prolonged consolidation kick in before a sustainable recovery emerges?"
• Although the availability of capital has been constrained on all levels, the analysts said they have witnessed successful equity underwritings of several small to mid-cap equities. Nevertheless, they advised that, until "a shift in sentiment towards explorecos improves, we expect capital to remain tight among the small caps." Canaccord believes equity raised next year for explorers and developers "will be limited to above-average opportunities."
• M&A Activity: "We believe the circumstances currently prevailing within the small cap mining space could open the potential for a series of mergers and acquisitions. Compounding this is the lack of capital available to juniors, which could be also a motivating factor to build on the M&A environment."
• New Discoveries: ‘With fewer explorecos actually conducting exploration work, the chances of a discovery in 2009 are declining. That said an attention-grabbing discovery could have a greater impact given the small circle of active explorers for investors to concentrate on."
• Industry Challenges: "Access to capital, declining metal prices and an apathetic investment climate are serious concerns in 2009."
Given the unknowns associated with a broad junior mining market turnaround, the analysts suggested that small-cap exposure "be associated with well-managed, cash-rich companies that will maintain active, but modest, exploration/development programs on top quality targets over the next 6-18 months."
Canaccord Adams highlighted 12 small-cap mineral exploration/development companies that have "strong working capital positions, above-average strong portfolios and strong management teams." They include B2Gold, Colossus Minerals, Exeter Resources, Fronteer Development Group, Hathor Exploration, Lake Shore Gold, MAG Silver, Minera Andes, Northern Dynasty Minerals, Rainy River Resources, Silverstone Resources, and Ur-Energy.
The currently prevailing circumstances prevailing within small-cap mining "create the potential for a series of mergers and acquisitions," the analysts suggested.
"Mergers among the small caps could increase as management teams become ‘humbled' by current market conditions and recognize that combined entities could, in the long term, result in improved shareholders value," they noted. "In other cases, the combination of cash-rich companies with property-rich companies could synergistically result in improved shareholder value."
"We expect additional M&A activity to drive some renewed speculative appeal over the next several months," the analysts advised. Canaccord Adams outlined several possible M&A targets including Anatolia Minerals, Andina Minerals, Aquiline Resources, Bear Creek Mining, Candente Resources, Canplats Resources, CGA Mining, Colossus Minerals, Comaplex Minerals, and Corriente Resources.
Other prospective M&A targets include Detour Gold, Donner Metals, GlobeStar Mining, Grayd Resource, Hathor Exploration, International Tower Hill Mine, Minera Andes, Osisko Mining, Rainy River Resources, Rubicon Minerals, Tournigan Energy, Ur-Energy and VMS Ventures.
