The Dave 3 (La France) occurrence is located in the south eastern head waters of La France Creek, approximately 8.5 kilometres east of the creek mouth on Kootenay Lake.
The area is underlain by siltstone, argillite, quartzite and dolomite of the Middle Proterozoic Dutch Creek Formation (Purcell Supergroup) and folded limestone, dolomite, argillaceous schist and chloritic schist of the Upper Proterozoic Horsethief Creek Group.
Locally, brecciated limestone and quartzite host mineralized quartz-carbonate veins contain limited galena, sphalerite, pyrite, tetrahedrite, chalcopyrite, barite and fluorite. Replacement-type mineralization is reported in the quartzite, near the contact with the argillite. The mineralization has been followed, intermittently, over a strike length of approximately 400 metres. Oxidation and sericite alteration is also reported.
In 1980, sampling of trench T+600 yielded up to 1.15 per cent zinc over 9.7 metres, while grab samples (K110R to K1112R) from trench T+300 assayed up to 1.69 per cent zinc, 0.165 per cent lead, 1.1 grams per tonne silver and 0.228 per cent barium, and grab samples (K109R and K110R) from trench T+700 assayed up to 1.82 per cent zinc, 0.129 per cent lead, 0.9 gram per tonne silver and 0.216 per cent barium (Assessment Report 8640).
In 1981, diamond drilling intersected disseminated galena and sphalerite mineralization in a carbonate close to the contact with an overlying argillite. No assays were reported from the drill core.
In 1990, rock sampling yielded up to 72.2 grams per tonne silver, 0.543 per cent zinc, 1.90 per cent lead (RV9020; Assessment Report 20708). Re-sampling of past drill cores, performed the same year, yielded values up to 0.165 per cent lead, 0.100 per cent zinc and 7.5 grams per tonne silver over the last 3 metres of hole 81K1, while drill hole 81K3 intersected 0.168 per cent lead, 0.196 per cent zinc and 6.7 grams per tonne silver over 3 metres (Assessment Report 20708).
During 1975 through 1979, David Wiklund conducted programs of soil sampling on the area as the Dave claims. In 1980 and 1981, Norcan Energy Resources completed programs of rock and soil sampling, geological mapping, trenching, a ground electromagnetic survey and seven diamond drill holes, totalling 478.7 metres, on the area. In 1990, Cominco completed a program of geological mapping and rock, soil and previous drill core sampling on the area. In 1995, Hunter Resources completed a program of prospecting and minor trenching on the area. In 2011, Teck Resources completed a program of geological mapping on the area as the Crawford property.
