Capsule Geology

The Mitchell and Cochrane showing is located 9 kilometres north- west of Vernon, north of Bradley Creek.

Sedimentary and volcanic rocks of the Upper Triassic to Lower Jurassic Nicola Group are in probable unconformable contact with Devonian to Triassic sedimentary and volcanic rocks of the Harper Ranch Group. Middle Jurassic granitic rocks intrude the Nicola and Harper Ranch. Outliers of Eocene Kamloops Group volcanic rocks are present in the area.

Two quartz veins within Nicola argillite host lead, silver, copper and zinc. The parallel veins, averaging about 2 metres thick, carry disseminated pyrite, galena, chalcopyrite and sphalerite. The east/west striking veins dip steeply south and can be traced on surface for about 60 metres. Sorted samples assayed up to 300 grams per tonne silver and 15 per cent lead (Minister of Mines Annual Report 1922, p. 145). Sulphides also occur in the wallrocks.

Some exploration work was carried out in 1922.
