The Lake occurrence is located on a low northwest-trending ridge, approximately 16 kilometres east-southeast of Mount Milligan.

The area of the Lake property is underlain by Upper Triassic Takla Group intermediate fragmental volcanics, a monzonite dyke of indeterminate age and an amphibolite thought to belong to the Permian Slide Mountain Group or possibly the Upper Cretaceous to Eocene Wolverine Metamorphic complex.

Graphitic siltstone/argillites were found to be the main cause of induced polarization anomalies found in 1991 and 1992. Rare to trace amounts of chalcopyrite were recorded along a monzodiorite /volcanic contact in drillhole 92-886 from the 175 to 180 metre interval. Trace chalcopyrite blebs were also found in an augite porphyry flow at 212 metres depth. No other copper mineralization was observed. Up to 5 per cent pyrite and traces of pyrrhotite were also observed.

Work History

In 1989, HLX Resources completed a program of rock and soil sampling on the area immediately west of the occurrence as the KC 1-2 claims. Samples of float volcanic boulders with pyrite and chalcopyrite from the KC 2 claim yielded up to 0.365 per cent copper, 0.025 per cent molybdenum, 12.9 grams per tonne silver and 0.444 gram per tonne gold (Sample KC11R; Assessment Report 19396).

In 1990, Dellaterra Resources Ltd. completed a program of prospecting and geochemical sampling on the area as the Lake 1-2 claims.

Also in 1990, Continental Gold Corp. completed 11 overburden drillholes, totalling 538.6 metres, on the area as the Rain 1-74 placer claims and a 609.2 line-kilometre airborne magnetic and electromagnetic survey on the area as the See claims.

In 1991 and 1992, Placer Dome Inc conducted a work program on the Lake 1 and 2 and See 28 claims. In 1991, 564 soil samples were collected, 63.4 km of ground EM (VLF) and magnetomer surveying was completed and 61.5 km of IP surveying was done. In 1992, Placer Dome’s program consisted of 11.6 km of grid line installation, ground magnetics/VLF EM, and 14.3 km of induced polarization. A large induced polarization, chargeability anomaly located on the flank of a magnetic high was found. Four diamond drill holes totalling 603.7 metres were drilled to test the geophysical anomalies in two target areas.

Also in 1991, HLX Resources completed a 9.0 line-kilometre ground magnetic survey on the KC claims and D.L. Cooke completed a program of geochemical (rock and soil) sampling and a 1.9 line-kilometre induced polarization survey on the Lac 1-2 claims.

In 1995 and 1996, Pacific Mariner Explorations Ltd., later Abitibi Mining Corp., completed programs of soil sampling on the Lac 1 claim.

During 1999 through 2005, David Forshaw completed programs of prospecting, soil sampling and 4.6 line-kilometres of ground scintillometer surveys on the area immediately southeast of the occurrence as the Leah Marie claim.
