The Pink deposit is located 17 kilometres southwest of Vernon, on the steep slopes east of Okanagan Lake.
In this area, Devonian to Triassic sediments of the Harper Ranch Group are intruded by Middle Jurassic granitic rocks, which are intruded in turn by granite and hypabyssal equivalents of the Eocene Coryell Intrusions. Patches of Eocene Penticton Group volcanic rocks overlie the older rocks.
Eocene orthoclase granite has been quarried for industrial use.
