Location of the property : |
Yasinski property is located on the James Bay Territory (33F06), in the Province of Quebec, 550 km North of Matagami and 80 km South of the locality of Radisson and of Robert-Bourassa and La-Grande-2A hydroelectrical powerhouses. The property is easily accessible from the Transtaïga road (Km 11), via James Bay main road 109 North linking Matagami to Radisson. A tractor path provides access to all the property main deposits. There is a hydroelectric power line of 735 Kilovolts crossing the property North-South.

Geological Environment :
|
The Yasinski property is located in the Western-central part of the La-Grande Greenstone Belt. The 33F/06 sheet includes many types of deposits, more precisely within the south western part (Goutier et al. 1998, Gauthier et al. 1997, Sharma 1978). The previous geoscientifics studies, done by many mining exploration companies and by the Ministère des Richesses Naturelles du Québec (MRNQ) have pointed out the presence of economic mineralization in Cr-EGP, Cu-Ni-Co-EGP±Au and Au-Ag-As±Cu. The Yasinski property is quoted in many synthesis reports for its ultramafic intrusions of kilometric extension showing Cr-Ni-Cu-EGP mineralization.
These ultramafic intrusions are located in the immediate south extension of the mineralized horizon containing the Chromite deposit of Lac Menarik (Pro-Or Resources). Sampling campaigns, detail mapping and drilling executed previously by Companies like Platinor, Augyva and Noranda (GM-50180, GM-50181, GM-50517) have allowed to identify an important gold potential in association with EW shear zones and intermediate to felsiques volcanic lithofacies showing high silicification, biotitization and / or amphibolitization (see also Borduras 1988, 1993 and Belkabir 1996).

The numerous works done on this property identified seven (7) deposits in surface (5 chromium deposits, 1 copper-nickel deposit, 1 gold deposit) and 1 gold showing found in the hole 4+400 N-1 (2.09 g\t over 12 feet). All deposits and the showing were found inside of 6 Kilometres long strike.
The inferred resources of the chromium deposits are evaluated to 1,700,000 metric tonnes at 6.69% of Cr2O3 intersected in less of 150 meters at depth (Blanchet 1994). The Ni-Cu-Au-Pd deposit is evaluated to 357,000 metric tonnes of inferred resources at 0.28% Cu, 0.55% Ni, less than 1 g /t Au and (.5 to 1 g /t) Pd at less of 200m in vertical depth. The mineralization remains open at depth and in lateral extensions to the east between 2+700 and 3+200 lines in accordance with Melis data (Sagax 1990). The inferred resources of the gold deposits are evaluated to 92,000 metric tonnes grading 3.11 g /t. The deposit is open at depth below 150 meters (Borduas 1990).
The geological and geochemical surveys of 1997 on the Yasinski property have confirmed the presence of a main gold structure highly altered in the line 22+00 (Belkabir 1996). The grab samples analysed, gave : 16,128 ppb, 54,977 ppb, 34,426 ppb, 18,470 ppb, 8,522 ppb et 9,655 ppb in Au; and 389 ppm, 161 ppm, 27.8 ppm, 20 ppm, 28.6 ppm et 2.8 ppm in Ag. The mineralized structure follows the main gold discovery of 1989 (Borduas 1991).
The study of the whole available data has revealed the Ni-Cu, Au-Platinum and Palladium (Pd) potential of the property. Drill hole analyses (0+75) gave 0.2%Cu, 0.14%Ni, 0.66 g/t Pd over 8.45m and 0.17% Cu, 0.14% Ni, 590 ppb of Pd over 6.0 m. along the hole, and this at less of 75 m of depth (Borduas 1990).

Work done in 2006-2007

Fieldworks have started in April 2006. The exploration program consisted of line cutting, soil geochemistry, geophysics, prospecting, mapping, trenching, striping and sampling. Numerous samples coming from pedogeochemical surveys and lithogeochemical surveys were assayed by ALS CHEMEX of Val d’Or (Quebec). Summer 2006 field works (soil geochemistry and lithogeochemistry) have revealed economic gold grades (1 to 74g/t Au in chosen samples) in detritic sediment horizons thus confirming the very high gold potential of this property. This mineralization context shows many similarities with that of the Eleonor gold deposit recently discovered by Virginia. Preliminary data from soil sampling (2006 campaign) reveal anomalic Uranium values up to 6 ppm.
Furthermore, in order to delineate new sulphide targets, a VTEM airborne geophysical survey totalizing 894 line kilometres was performed by Geotech Ltd of Aurora (Ontario), over the Yasinski property in November 2006. Reports and maps were produced in February 2007, and are under study. Diamond drilling will follow on priority targets.
