The Ponderosa occurrence is located on a small ridge west of Anderson Lake, approximately 4.5 kilometres north- north east of the community of D’Arcy.

The area is underlain by argillite and phyllite of the Mississippian to Jurassic Bridge River Complex (Group).

Locally, a north- trending shear hosted by a calcareous and silicified argillite is mineralized with chalcopyrite, malachite and azurite. The contact with a Cretaceous to Tertiary granitic mass, probably related to the Bendor pluton, occurs a few tens of metres to the east.

In 1989, samples yielded values up to 44.8 grams per tonne silver and greater than 1.0 per cent copper over narrow widths (Assessment Report 19604).

In 1983, X-Cal Resources completed a program of rock and silt sampling and geological mapping on the area as the Mac and X-Cal claims. In 1985, Hudson Bay Exploration and Development completed a program of geochemical sampling, geological mapping and a ground electromagnetic survey. In 1989 and 1990, Teck completed programs of rock, silt and soil sampling, geological mapping and a ground electromagnetic survey on the area. In 1991, Cogema completed a program of geochemical sampling and geological mapping on the area.
