DIOS EXPLORATION: Porphyry Type Gold Potential Evidences on 33 Carats
(firmenpresse) - MONTREAL, CANADA -- (Marketwire) -- 06/22/12 -- On its porphyry type 33 CARATS gold project located NW of the Eastmain gold mine some 315 kilometers north of the town of Chibougamau, DIOS EXPLORATION (TSX VENTURE: DOS) plans to shortly start mapping and prospecting the tonalitic phase of the Erasme Lake pluton. The Otish Mountains road which will go to the diamond Renard deposit passes less than one to two kilometers east of the sector targeted by DIOS. In 2011, many tonalite boulders returned from 0.97 to 3.18 g/t Au up-ice of a gold in till glacial train (252 - 2,090 ppb Au (from 0.25 g/t Au to 2.09 g/t Au)).
Recent analysis work of other diamond tills from DIOS allows us to add the following gold values in g/t in the tills (fine concentrates) along the gold dispersal glacial train which seems to stop in the tonalite: 2.5 g/t Au, 2.385 g/t Au, 1.320 g/t Au, 0.384 g/t Au, 0.352 g/t Au, 0.504 g/t Au, 0.731 g/t Au, 0.424 g/t Au and 0.301 g/t Au (Falcon concentrates). These new positive results allow the confirmation of the train and to define it more while enlightening its significance with many values greater than 2 g/t Au.
IOS Services Geoscientifiques will execute on behalf of DIOS soil sampling work (1,100 humus samples) on the sector poorly outcropping up-ice of the gold train to eventually target drilling areas. The till samples (sand from glacial erosion) were processed in their Saguenay laboratory.
Even more so, five rock samples from the glacial boulders were submitted to them for a petrographic study. They had returned anomalous values in gold and silver. Potassic alterations were suspected and confirmed by the petrographic study. Potassic alteration of the tonalitic-granodioritic rocks lightly mineralized in pyrite-chalcopyrite and in quartz veinlets shows favourable potential for porphyry gold type mineralizations.
Potassic alteration is characteristic of porphyry gold deposits such as in Malartic and such as is noted on DIOS Au 33 West gold project optioned to Osisko Mining Corporation.
Gold mineralization in these tonalite boulders correlates with significant values of copper and silver, and related values in bismuth, again indicative of porphyry type deposits. This press release was prepared par M.J. Girard, M.Sc.Geo, 43-101 QP.
