The CAMP HEWITT 12 showing is located above the confluence of Trepanier and Law creeks, approximately 1 kilometre upstream from the mouth of Trepanier Creek.

The area is covered by rhyolite, trachyandesite and andesite of the Eocene Marron Formation, Penticton Group except in the Trepanier Creek valley where the underlying Triassic-Jurassic Nicola Group rocks are exposed.

The showing consists of irregular pods, lenses and disseminations of pyrite, sphalerite, galena and chalcopyrite in Nicola Group limestone. The Nicola Group rocks form a pendant which is underlain by the Early Jurassic Pennask Batholith.

Evidence of early work on the showing is a caved adit, possibly dating from the 1890s when the Camp Hewitt Mining and Development Co. was active in this area, or from the late 1950s when some stripping was carried out on the LAKEVIEW (082ENW020) showing to the west. The adit was driven northeasterly into a limestone outcrop and exposed a pod of massive sphalerite with a minor amount of galena. In 1965, King Resources Company carried out a prospecting and mapping program in the area, and in 1966 they followed up with a 4-hole, 62.6-metre diamond drill program. Hole number 2 was collared on a massive sulphide lens which proved to be only 4 centimetres thick; and only traces of sulphides were encountered after the first 0.46 metre. The other 3 holes did not intersect any mineralization of note. In 1972, Vega Mines Ltd. examined the showing.

A high-grade grab sample assayed 0.72 per cent copper, 4.9 per cent zinc, 2.24 per cent lead, 144 grams per tonne silver and 0.2 grams per tonne gold (Property File - Philp, R.H.D. (1972): Report on the ROHANNA, KEL and ZN Claims).
