The Collex showing is located 500 metres southeast of McCall Lake, approximately 3 kilometres northwest of Peachland.

The showing consists of chalcopyrite and molybdenite disseminated in propylitically altered granodiorite of the Early Jurassic Pennask Batholith. The mineralization occurs near a contact with Triassic-Jurassic Nicola Group andesite.

The showing was explored by Cambri Mining and Development Ltd. in 1966, who carried out a soil sampling and an induced polarization survey. Copper and molybdenum soil anomalies and a chargeability anomaly were identified in the vicinity of the COLLEX showing. In 1979-80, Brenda Mines Ltd. carried out a soil geochemical survey which identified a lead-zinc anomaly near the COLLEX showing; copper and molybdenum soil geochemistry did not appear to be a useful exploration technique.
