The Clair 13 occurrence is located west of East Creek, a northeast tributary of Matthew Creek, at an elevation of approximately 2150 metres, approximately 4.7 kilometres northwest 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, as identified by drilling, a major fault zone (Alki Fault?), intercepted from 439 to 452 metres down hole, hosts a foliated, sheared and chlorite-sericite– altered fault breccia with sericite-clay-chlorite-sphalerite-galena veins near the contact with a gabbro sill.

In 2000, drill core samples from hole PP-00-1 assayed up to 4.56 per cent lead, 11.6 per cent zinc and 73.9 grams per tonne silver over 0.23 metre (Assessment Report 26361).

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, Cleo 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, rock sampling and a diamond drill hole, totalling 758.5 metres.
