The Wel 15-16 occurrence is located west-southwest of a small lake or pond approximately 1 kilometre northwest of Wells Lake, approximately 29 kilometres west-southwest of Princeton.

This area in the vicinity of Wells Lake is underlain by biotite granodiorite of the Late Jurassic to Early Cretaceous Eagle Plutonic Complex.

Locally, a zone of copper-molybdenum mineralization, 550 metres wide, trends 145 degrees for at least 1000 metres, roughly paralleling the regional foliation of the area. The zone contains numerous quartz veins mineralized with pyrite and chalcopyrite, and sporadic molybdenite. Intersecting pyrite-chalcopyrite-bearing veins are noted to strike in three distinct directions. Chalcopyrite also occurs as disseminations and as blebs along fractures in the enclosing granodiorite.

In 1974, a sample (8456) from a quartz vein with pyrite, chalcopyrite and molybdenite analysed 0.89 per cent copper, 9.3 grams per tonne silver, 0.145 gram per tonne gold and 0.0245 per cent molybdenum; while another sample (8451) of quartz vein with chalcopyrite and pyrite yielded 0.240 per cent copper, 36.0 grams per tonne silver and 0.460 gram per tonne gold (Assessment Report 5564).

In 1974 and 1976, Canadian Occidental Petroleum completed programs of rock, silt and soil sampling, geological mapping and a ground magnetic survey on the area as the Wel claims. In 1979, Canadian Natural Resources, on the behalf of Georgia Resources, completed a program of geological mapping, soil sampling and ground magnetic and induced polarization surveys on the area immediately north and west. In 2010, the area was prospected by L. Sookochoff.
