The Dck showing is located 8 kilometres east-northeast of Vernon, on the north side of Vernon Hill.

In this area, east of the Okanagan Valley fault, Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks unconformably overlie Devonian to Triassic sedimentary and volcanic rocks of the Harper Ranch Group. These units are faulted over gneissic rocks of unknown age and metasedimentary rocks of the Proterozoic Silver Creek Formation. Middle Jurassic granitic rocks cut all of the above rocks. Outliers of Eocene Kamloops Group volcanic and sedimentary rocks cap the older units.

Metamorphosed volcanic rocks (chlorite schist) of the Nicola Group host copper mineralization. Disseminated pyrite and chalcopyrite occur in a trench and 130 metres to the east in volcanic rocks, probably associated with shearing. A 0.3-metre thick massive pyrite vein was also noted.

From 1968-1974, King Graybarr Mines Ltd. carried out trenching, geological mapping, airborne magnetometer and drilling programs. In 1975 Canadian Superior Exploration Ltd. conducted a program of geological mapping and drilling.
