The Esperon 3 showing is located 28 kilometres north northwest of Kelowna, north of Terrace Creek.
In this area, Middle Jurassic quartz monzonite of the informally named Terrace Creek batholith intrudes argillaceous sediments of the Upper Triassic to Lower Jurassic Nicola Group. The stock is cut by diorite plugs and dikes which are cut by quartz monzonite and aplite dikes. The intrusive rocks are cut by Tertiary basalt dikes related to overlying Eocene Penticton Group volcanic rocks.
Chloritized and sericitized porphyritic quartz monzonite hosts molybdenum mineralization. Quartz veinlets carry traces of disseminated molybdenite and pyrite.
In 1979 and 1980, Cominco Ltd. carried out geological mapping, induced polarization and magnetometer surveys.
