The Ein showing is located 22 kilometres northwest of Vernon, on the steep slopes south of the Salmon River.

In the area, sedimentary and volcanic rocks of the Upper Triassic to Lower Jurassic Nicola Group are in fault contact, to the north, with Cambro-Ordovician volcanic (Tsalkom Formation) and sedimentary (Sicamous Formation) rocks. To the south, the Nicola Group is in probable unconformable contact with Devonian to Triassic sedimentary and volcanic rocks of the Harper Ranch Group. Cretaceous granodiorite plugs intrude the Nicola, Sicamous and Tsalkom rocks. Outliers of Eocene Kamloops Group volcanic rocks are present in the area.

Hornblende-talc schist, phyllite, argillite and andesite of the Nicola Group underlie the property. Some of these units host copper mineralization comprising pyrite and rare chalcopyrite.
