Lac Doré

EXPLORATION PROJECT

The Lac Doré deposit is located approximately 3 km by road southeast of Chibougamau and 600 m southwest of the Copper Rand mill.

The Lac Doré deposit is within a 150 m wide northwest sericite altered deformation corridor which extends for approximately 1 km. The deposit starts at 80 m below surface and has been tested over a strike length of approximately 500 m. It consists of a series of en echelon veins, varying in thickness from 0.3 to 7.7 m, that extend from 150 to 300 m. The mineralized lenses are heavily faulted north-northeast at 15 to 30 m intervals. The mineralization at Lac Doré is similar to Cedar Bay (off-set along the Lac Doré fault). 

The Lac Doré deposit was drilled in a few different phases from 1984 to 1992. A total of 47 drill holes from surface are reported during that period. A double ramp was excavated in 1991-92 followed by an underground drilling campaign of 46 holes totaling 10,200 metres testing the deposit mainly to a depth of 240 meters (only 5 holes tested the deposit between 300 and 600 meters). At the end of 1992, Westminer Canada reported a measured and indicated resource of 209,120 tonnes at 1.23% Cu and 5.4 g/t Au and a small mineral reserve for veins 45-2 and 25-4 (non-NI 43-101 compliant). The deposit remains open to depth (below 400 meters) and along strike towards the Lac Dore fault.
