The Esperon 17 showing is located 23 kilometres north-northwest of Kelowna, south of Esperon Creek.

In this area, Middle Jurassic quartz monzonite of the informally named Terrace Creek batholith intrudes argillaceous and calcareous sediments of the Devonian to Triassic Harper Ranch Group. The stock is cut by plugs and dikes of diorite which are intruded by quartz monzonite and aplite dikes. The intrusive rocks are cut by Tertiary basalt dikes related to volcanic rocks which overlie the older rocks.

Chloritized and sericitized quartz monzonite hosts molybdenum and zinc mineralization. Quartz veinlets carry disseminated molybdenite and pyrite.

About 1000 metres to the west, quartz veinlets carrying pyrite and trace sphalerite occur in a porphyritic quartz monzonite.

In 1979-80, Cominco Ltd. carried out geological mapping, induced polarization and magnetometer surveys.
