Colossus Minerals Provides Update on Exploration on Elefante Area
TORONTO, ONTARIO -- (Marketwire) -- 08/20/12 -- Colossus Minerals Inc. (the "Company" or "Colossus") (TSX: CSI)(OTCQX: COLUF) is pleased to announce assay results from the auger drilling program on the Elefante Area located at its 75% owned Serra Pelada Gold-Platinum-Palladium Project. The Serra Pelada Project is a Colossus-COOMIGASP joint venture located in the State of Para, Brazil.
HIGHLIGHTS
All of the assay results have now been received from the auger testing program conducted to define targets for the diamond drilling program to be conducted in the fourth quarter of 2012. Seventy-three auger holes were drilled to depths that ranged in length from two to nine metres. The final assay results of this auger drilling program returned the following highlights:
-- SPTRD-135 returned values of 13.08 g/t platinum and 4.19 g/t palladium
from 0.5 to 1.0 metre below surface.
-- SPTRD-160 returned values of 4.40 g/t gold from 1.5 to 2.0 metres below
surface.
-- SPTRD-169 returned values of 8.70 g/t gold from 1.5 to 2.0 metres below
surface.
Claudio Mancuso, President & CEO of Colossus commented, "The results of the auger drilling program highlight the potential of the Elefante Area and demonstrate Elefante's value as a target for diamond drilling. We are excited to be able to commence diamond drilling later this year as the high grade intercepts in soils close to surface could have immediate economic potential."
DETAILS
The most recent phase of auger drilling was designed to fine-tune the targeting of a trend of mineralization identified in the previous phase of auger drilling. This mineralization trend returned encouraging results from near surface soil samples down to the saprolite portion of the hole just above the presumed bedrock. The latest results continue to demonstrate that the soil contains local pockets of high grade precious metal mineralization. The previously released results highlighted a 10.5 metre long interval that returned 0.64 g/t Au, 0.12 g/t Pt and 0.08 g/t Pd from auger hole SPTRD-090 (see press release dated March 12, 2012 for more details). This was a follow-up to an earlier phase of testing that highlighted holes SPTRD-016 that returned a 5.5 metre interval of 0.20 g/t Au, 0.53 g/t Pt and 0.45 g/t Pd from the saprolite and SPTRD-017 that contained 124.78 g/t Au, 6.52 g/t Pt and 7.67 g/t Pd from a 0.50 metre soil sample interval (see press release dated November 14, 2011 for more details).
As noted above, a total of 73 additional auger holes were drilled in the final phase of auger drilling in this area (see figures 1 and 2 attached). The results are highlighted in Table 1 below and add to the interpretation of the anomalous samples identified in the previous phases of auger drilling over this area. The resulting interpretation shows a broad low grade east-west trending halo predominantly coming from soil samples of the regolith. There are two higher grade clusters within this broad anomaly, the southernmost of which is associated with the holes that have encouraging precious metal results in the saprolite (see figure 3 attached). Diamond drill testing in the area will commence on the mineralized trend of which these three holes are a part. This work will help identify whether the high grade soil assay results are bedrock sourced.

Elefante Area Geology
The Elefante Area is located approximately two kilometres southeast of the Serra Pelada Au+Pt+Pd deposit (see Figure 1 in this release). The host rock in this area consists of Archean aged (2.68 billion year old) sediments belonging to the Rio Fresco Formation which also hosts the Serra Pelada orebody. Outcrops of siltstone found in the Elefante area physically resemble those found in the pit wall of the historic Serra Pelada open pit but lack the classic reddish color of the oxidized sediments. The siltstone found in the Elefante area is a light to medium grey color.
Diamond Drilling
The first phase of drilling will consist of approximately 500 metres of HQ caliber drilling and will test for the bedrock source of the saprolite enriched auger drill holes as well as test the fold of the sedimentary package for signs of carbon upgrading similar to that which is found in the high grade Central Mineralized Zone at the Serra Pelada Mine.
Technical Information
Auger sampling is conducted using a mechanical auger. Sampling of the drilled material (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, the sampled intervals (drilling advances, averaging half a metre in length) were cut and/or split in half, yielding samples of two to three kilogram mass. Where sample recoveries were low, intervals were composited to yield approximately one kilogram minimum sample masses. 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. A 200 gram aliquot of medium and high grade pulps were rotary split from each pulp by Intertek and SGS Geosol and one of these samples was securely shipped directly by Intertek to Genalysis Limited, Perth Laboratory for check assaying. A similar procedure is used for samples assayed at the SGS Geosol lab with the samples being securely transported to the Intertek lab in Parauapebas, Brazil for check assaying.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION
Forward-looking statements in this press release include statements regarding the timing and nature of future exploration and development programs that are dependent on projections that may change as drilling continues, or if unexpected ground conditions are encountered. The Company does not currently have any mineral properties that are in production or that contain a reserve as defined by National Instrument 43-101. In addition, areas of exploration potential are identified which will require additional drilling to determine whether or not they contain similar mineralization to areas that have been explored in more detail. Significant additional drilling is required at Serra Pelada to fully understand system size.
