The results are currently being interpreted and the immediate focus of the follow-up drilling will be to expand the known zone and define its limits.
Serra Pelada Geology
Gold-platinum-palladium mineralization at Serra Pelada overprints metasediments occupying the hinge of a large fold. The CMZ comprises mainly a steep dipping carbonaceous alteration zone in the fold hinge that also extends onto the upper and lower limbs of the fold for a limited distance. The Lower Limb represents shallow-dipping, gold-platinum-palladium mineralization predominantly associated with an iron oxide rich breccia as well as iron oxide rich argillic alteration and locally carbonaceous alteration on the lower limb of the main fold. The upper limb mineralization is characterized by an iron oxide rich breccia similar to that found in the Lower Limb. The lithologies containing mineralization at the Elefante area do not share the same characteristics or degree of alteration as the typical ore zone at the Serra Pelada Mine and may represent a new target for ore on the property.
Diamond drilling was HQ cored. Sampling of core by Colossus personnel and sample preparation by Intertek Limited, Parauapebas and/or SGS Geosol, Parauapebas, Brazil were carried out under strict protocols recommended in the National Instrument 43-101 Technical Report dated January 31, 2010 on the Serra Pelada Project. After photographing and logging, core sample intervals were cut and/or split in half, yielding samples of various weights depending on the sample length. Where core recoveries were low, intervals were composited to yield approximately one kilogram minimum sample mass. Intertek and SGS Geosol pulverize one or two kilogram splits (greater than 95% passing 106 microns) from the crushed (greater than 95% passing 1.7 mm), dried samples. Duplicates, blanks and certified gold-PGE reference materials were inserted in the sample train by Colossus personnel prior to Intertek preparation work.
The labs insert additional blanks, duplicates and high grade gold/PGE reference materials in the assay stream and replicate or duplicate assays were performed routinely and on most medium- to high-grade materials. Fire assays for gold, platinum and palladium were on 25 gram subsamples utilizing a lead-rich collector material and AA finish.
The Intertek and SGS Geosol assay results for blanks, duplicates, replicates and also all reference materials were well within generally accepted QA/QC measures.

Colossus is a development-stage mining company focused on bringing its 75% owned Serra Pelada Gold-Platinum-Palladium Mine to production. The Serra Pelada Mine is a joint venture between Colossus and Cooperativa de Mineracao dos Garimpeiros de Serra Pelada (COOMIGASP) located in the State of Para, Brazil. Serra Pelada, located in the mineral prolific Carajas region in the State of Para, Brazil, is host to one of the highest grade gold and platinum group metals deposits in the world. Between 1980 and 1986 Serra Pelada was host to the largest precious metals rush in Latin American history. Colossus Minerals shares, warrants and notes trade on the Toronto Stock Exchange (TSX) under the symbols CSI, CSI.WT.A and CSI.NT respectively and in the United States its Common Shares trade on the OTCQX under the symbol COLUF. The Company is headquartered in Toronto, Canada.
