The West Peak occurrence is in the southeastern head waters of Wuhun Creek on the western peak of Mount Bigattini, at an elevation of approximately 2300 metres.

The area is underlain by siltstone, argillite and quartzite of the mid-Proterozoic Creston Formation (Purcell Supergroup). These have been regionally metamorphosed to greenschist facies and have been intruded by gabbro to diorite sills and dikes of the mid-Proterozoic Moyie Intrusions.

Locally, a breccia zone with quartz, limonite and hematite hosts gold values. In 1991, two rock samples (83081 and 83082) assayed 1.01 and 3.83 grams per tonne gold, whereas a float sample (52184) yielded 16.47 grams per tonne gold (Assessment Report 21863).

Another zone of mineralization located approximately 400 metres to north-northeast, consists of narrow quartz veins with galena, malachite and limonite. In 1991, a rock sample (83095) assayed 0.605 per cent lead, 44.2 grams per tonne silver and 1.90 grams per tonne gold (Assessment Report 21863).

During 1987 through 1991, Chapleau Resources completed programs of silt, soil and rock sampling, trenching, geological mapping, a 14.8 line-kilometre combined ground electromagnetic and magnetic survey and a 200 line-kilometre airborne geophysical survey on the area as the Racki and LDM claims.
