The Red Dog occurrence is located on a ridge east of Lens Creek, approximately 500 metres north east of Doe (Frost) Lake.

The area is underlain by massive volcanic rocks, dominantly basalts and andesites, of the Upper Triassic Karmutsen Formation, Vancouver Group. Overlying these are massive limestone of the Upper Triassic Quatsino Formation, Vancouver Group. The strata has been cut by several stocks and dyke/sill swarms ranging in composition from diorite to aplite and dacite, sometimes feldspar- phyric. These rocks are bounded to the north, east and south by a large mass of intrusive rock of the Lower to Middle Jurassic Island Plutonic Suite.

A diorite stock, about 250 by 320 metres wide, has cut along an apparently northwest trending contact (or fault) between massive limestone and andesitic volcanics. The stock exhibits moderate pyritization (3 per cent) with occasional chalcopyrite along close- spaced joints and fractures.

Several skarn showings have been developed in both the volcanic and limestone units at or near intrusive contacts. The skarns are up to 5 metres wide and contain varying amounts of sulphides, locally massive. Mineralization is typically podiform, discontinuous and leached. Two types of skarns have been developed: 1) garnet, actinolite, plus or minus chalcopyrite and pyrite in limestone adjacent dacite dykes; and 2) massive magnetite, chalcopyrite and pyrite with lesser amounts of garnet, epidote, actinolite and quartz in basalt or basaltic tuff. Other minerals which have also been reported in the skarns include goethite, covellite, malachite, azurite and rare pyrrhotite and sphalerite.

In 1977, Western Mines Limited completed a ground magnetometer survey and sampled part of one area, 60 by 180 metres, containing numerous skarns formed at the south end of the diorite stock. Six samples ranging from 0.6 to 2 metres in width, four of which were leached gossan, assayed from 0.149 per cent copper to 1.71 per cent copper, from 2.74 to 15.43 grams per tonne silver and from 0.03 to 0.10 grams per tonne gold (Assessment Report 6502, Figure 9).

In 1984 through 1988, Beau Pre Explorations Ltd. Completed a program of geochemical sampling, geophysical surveys and prospecting on the area. In 1985, a sample (FL-4) of massive sulphide assayed 3.1 grams per tonne silver, 0.52 per cent copper and 21.66 per cent iron (Assessment Report 14565). In 1986, a continuous chip sample across 3 metres of the zone yielded 0.68 per cent copper, 0.06 per cent zinc and 11.0 grams per tonne silver. Another chip sample, taken 20 metres to the north, assayed 1.52 per cent copper and 7.2 grams per tonne silver over 1.0 metre (Assessment Report 15295).

In 2005 through 2009, Le Baron Prospecting completed programs of geochemical sampling and prospecting on the area as the Doe Lake Project. In 2005, grab sampling yielded values up to 229 grams per tonne silver, 3.18 per cent copper, 18.5 per cent lead and greater than 30.0 per cent zinc (Assessment Report 28668). In 2008, grab samples assayed up to 5.36 per cent copper (sample H031069; Assessment Report 30643)
