The Klondyke showing is located 14 kilometres west of Vernon, on the west side of Okanagan Lake.

In this area, Devonian to Triassic sedimentary and volcanic rocks of the 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. Eocene Penticton Group volcanic rocks overlie the igneous and sedimentary rocks.

Quartz veins within granodiorite near the contact with argillite and marble of the Harper Ranch host copper and gold mineralization. The irregular quartz-calcite veins occur in an area of fracturing, brecciation and chlorite and silica alteration. The veins are up to 1 metre thick and carry minor disseminated pyrite, chalcopyrite and "gold values".

By 1899, two shafts, 15 and 2.5 metres deep, had been sunk. In 1986, Tournigan Mining Exploration Ltd. carried out geological mapping.
