The Pat showing is located 24 kilometres west-southwest of Vernon, on the steep south side of Whiteman Creek valley.

In this area, sedimentary and volcanic rocks of the Devonian to Triassic Harper Ranch Group are intruded by Middle Jurassic granitic rocks. An Eocene Coryell rhyodacite to syenite porphyry, high-level plug intrudes and is in fault contact with the Jurassic intrusions. Eocene Penticton Group volcanic rocks overlie the igneous and sedimentary rocks.

An altered, bleached, fractured and brecciated zone within the rhyodacite porphyry hosts Tertiary, possibly Eocene, copper mineralization. Chalcopyrite, bornite, jarosite and limonite are reported. Alteration envelopes of kaolinized feldspars, talc(?) and silicification occur along fractures, usually less than 10 centimetres thick.

In 1967-68, Noranda Exploration Co. Ltd. carried out a program of geological mapping, soil geochemistry and drilling.
