Dios Exploration Inc. plans to undertake field work (including prospecting, mapping, trenching) on wholly-owned AU33WEST gold property, a few km from the Eastmain-1 hydropower facilities, James Bay area, Quebec.
Main target focus will be the extent of the Héberto gold showing that assayed up to 5 g/t Au over some 5 meters in diamond saw track-sampling. This gold showing is coincidental with a weak induced polarization conductor (chargeability) north-south striking along the margin of a sub-circular magnetic anomaly, itself included within a larger low magnetic structure. Several gold soil anomalies are also coincidental with induced polarization conductors. A structurally-controled oxidized IRG (Intrusion Related Gold) model is proposed for the AU33WEST gold project.
A felsic (tonalite-granodiorite) intrusive complex hosts several gold porphyry-type showings (grading from 1.77 to 23 g/t Au in grab samples) within a 5,0 by 2,0 km area at the head (up-ice) of a significant gold glacial dispersal train. The gold mineralization appears as 1-5% pyrite as disseminations and fracture fillings that are associated with potassic alteration and/or silicification. It appears structurally controlled by zones of shearing and foliation along two main orientations (N160 and N080E).
Recent compilation of the AU33W data show good correlation between gold and presence of pyrite, (of chalcopyrite) and/or magnetite-hematite (oxidized system) located at the margins of intrusions. The intrusions are interpreted from total field & vertical gradient magnetics and geological mapping. These associated mineralizations are enclosed within large halos of potassic feldspar, silica, epidote, magnetite-biotite and hematite alterations. The juxtapposition of structural measurements and magnetic data suggests the presence of buried intrusive domes within the mineralized and altered area which is mainly developped along a north-south structural vector in the plutonic domain. The concentration of sulfidic mineralization along the margins of distinctive magnetic intrusions is also coincidental with higher potassium content (ground spectrometry).
