The Equesis Creek showing is located 16 kilometres northwest of Vernon, on Equesis Creek near Musgrave Creek.

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 of the informally named Terrace Creek batholith. Eocene Penticton Group or Kamloops Group volcanic rocks overlie the igneous and sedimentary rocks.

Quaternary gravels along the creek host placer gold mineralization. Good values are reported along sections of Equesis Creek, particularly in the vicinity of its junction with Musgrave Creek.
