The Clair 12 occurrence is located near the southern head waters of a north flowing tributary of Matthew Creek, approximately 3.5 kilometres north west of Bootleg Mountain.

The area is underlain by argillites and quartzites of the middle Proterozoic Aldridge Formation (Purcell Supergroup). These have been intruded by gabbro sills and dikes of the middle Proterozoic Moyie Intrusions.

Locally, a silicified and weakly chlorite- altered quartzite with quartz-limonite-carbonate veinlets hosts galena mineralization.

In 1996, two rock samples (SP-25411 and SP-25412) yielded up to 0.665 per cent zinc, 66.3 grams per tonne silver and greater than 1 per cent lead (Assessment Report 24877).

In 1985 and 1986, Amstar American completed programs of geological mapping, soil and rock sampling and ground and airborne geophysical surveys on the area as the Bootleg claims. In 1993, Cominco completed an 8.5 line-kilometre ground electromagnetic survey on the area as the Mat claims. Also, in 1996, Eagle Plains Resources Ltd. and Miner River Resources Ltd completed a two-day geological reconnaissance program consisting of stream sediment sampling and prospecting. During 1996 through 1999, Abitibi Mining completed exploration programs of rock, soil and silt sampling, prospecting and geological mapping on the area as the Clair and PMR claims. In 1999 and 2000, Rio Algom Exploration completed exploration programs on the area as the Pyramid Peak property consisting of geological mapping and rock sampling.
