Capsule Geology

The Mission Hill East showing is located 8 kilometres south- southwest of Vernon, west of Kalamalka Lake.

In this area, west of the Okanagan Valley fault zone, volcanic and sedimentary rocks of the Devonian to Triassic Harper Ranch Group are unconformably overlain by Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks. These units are intruded by Middle Jurassic granitic rocks informally named the Terrace Creek batholith. Granitic Coryell rocks of Eocene age intrude these units and patches of Eocene Kamloops Group volcanic rocks overlie older rocks.

Quartz-calcite stringers and lenses within Middle Jurassic quartz diorite host silver, copper and gold mineralization. The irregular stringers and lenses carry disseminations, streaks and bunches of pyrite and minor chalcopyrite. The zone of quartz is several metres wide. The wall-rock also contains disseminated sulphide mineralization.

By 1931, exploration had been carried out by means of a 60-metre tunnel.
