The Lake occurrence is located approximately 1.9 kilometres north of Mount Carruthers.

The regional geology is similar to that of the Carruthers Creek occurrence (refer to 094D 060). The occurrence is hosted in sedimentary rock of the Upper Triassic Dewar Formation (Takla Group), near a contact with Lower Jurassic volcanic rocks of the Telkwa Formation (Hazelton Group).

Chalcocite and bornite, with minor amounts of native copper and malachite, are disseminated within a grey to black shale unit. Sample Cu3 assayed 2.30 per cent copper, 6.1 grams per tonne gold, and 5 parts per billion gold and Sample Cu1 assayed 2.83 per cent copper (Figure 2, Assessment Report 18175).

WORK HISTORY

In 1976, Robert M. Tait conducted a prospecting program on his North and Lake claims about 1.75 kilometres north of Mount Carruthers (Assessment Report 5927). Chalcocite, bornite, native copper and chrysocolla were located along an east-southeast trend on the south half of the Lake claim, over about 500 metres. Location of claims and mineralization was vague. No assays were reported.

In 1988, Mr. Tait conducted another prospecting program on his 5-unit Car 1 to 5 claims. Sample Cu3 was taken about 1.2 kilometre east from Caruthers Creek to the north-south trending ridge, about 1.9 kilometres north of Mount Carruthers. Sample Cu3 was collected several hundred metres east-southeast of the Car claim group. It is not clear if Sample Cu3 was collected in the area of the copper mineralization reported by Mr. Tait in 1976.

In 1997, Robert Tait visited the Fog claim with geologist Jim Miller-Tait. Six rock samples were collected for analysis.

In 2021, Golden Tiger Minerals Inc. collected 16 rock samples from various areas and lithologies from the three areas: 7 from the Mona Jean (094D 106), 7 from the Mar (094D 093) and 2 from the Lake (094D 108) (Assessment Report 39601).
