In this area, sedimentary and volcanic 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. Eocene Penticton Group volcanic rocks overlie the igneous and sedimentary rocks.

Altered volcaniclastic rocks of the Harper Ranch Group host copper mineralization. Disseminated and veined chalcopyrite and pyrite mineralization occurs within calc-silicate skarn.
