Capsule Geology

The Lakeview (Lot 14277) is located on the east shore of Kootenay Lake about 0.5 kilometre south of the mouth of Sanca Creek. The old adit is driven under Highway 3A. The Crown grant was forfeited in June of 1990; the area was recently explored as the Sanka #5 claim (Assessment Report 11988).

The claims are underlain by sedimentary rocks of the Creston Formation, part of the Purcell Supergroup of Middle Proterozoic age. These rocks comprise quartzite and siliceous limestone, and form a roof pendant that is underlain at some depth by quartz diorite of the Cretaceous Bayonne batholith. A narrow porphyry dike is found with the mineralization in places.

On the old Crown grant, a lens of massive sulphide 7 metres long and 1.3 metres wide formed the main part of a system of lensy quartz and calcite veins mineralized with galena, sphalerite and minor pyrite and chalcopyrite. The veins occur in a northerly trending shear zone, some 100 to 150 metres north of the contact of the roof pendant with the surrounding batholith. The dip of the mineralization is steep to the east; the shear zone is from 3 to 6 metres wide.

Intermittent production from 1935 to 1953 resulted in 738 tonnes, yielding 136,698 grams of silver, 155 grams of gold, 231 kilograms of cadmium, 82,687 kilograms of lead and 175,185 kilograms of zinc.
