The Big Smoke South (PMR 62) occurrence is in a steep creek gully east of Both Creek and north of the St. Mary River, at an elevation of approximately 1250 metres.

The area is underlain by argillites, wacke 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 sheared and actinolite- altered gabbro in contact with a brecciated conglomerate hosts quartz veins with disseminated to patchy massive galena, sphalerite, chalcopyrite and scheelite. Gangue minerals include calcite, garnet, epidote, chlorite, sericite and minor tourmaline.

In 2010, four rock samples (SK10-4 to 7) assayed from 0.064 to 1.96 per cent lead, 0.032 to 0.796 per cent zinc, trace to greater than 0.01 per cent tungsten, 1 to 36.3 grams per tonne silver and up to 0.11 gram per tonne gold (Assessment Report 32219).

In 1979, Cominco completed a program of soil sampling and geological mapping on the area as the Clair claims. In 1982 and 1983, Cominco completed a ground electromagnetic survey and a seismic survey on the area. In 1992, Cominco completed a 14.0 line-kilometre ground electromagnetic survey on the area. 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 consisting of geological mapping and rock sampling on the area as the Pyramid Peak property. In 2001, Abitibi Mining completed a program of geological mapping on the area. In 2010, Kootenay Gold completed a program of rock sampling and geological mapping on the area as the Big Smoke property. In 2013, Electra Gold prospected the area. In 2014, the area was prospected and sampled by K. Craig. In 2014, Homegold Resources conducted prospecting and rock sampling.
