The Will occurrence is found approximately 2 kilometres east of the Manson River, approximately 5 kilometres northeast of the mouth of Munro Creek.

The area lies within the Omineca Crystalline Belt, which consists of siliciclastic sediments with minor carbonates and mafic rocks. These rocks belong to the late Proterozoic Ingenika Group. Within the Wolverine Range, the sediments are highly metamorphosed and subsequently intruded by granodioritic bodies and associated pegmatites, which are most likely Early Tertiary. The Proterozoic Wolverine Complex rocks consist of amphibolite and calcsilicate gneiss, schists, micaceous quartzite and crystalline limestone.

The occurrence area is underlain by monzonite (Mount Bisson intrusions), metasomatized Wolverine Complex schists and gneisses (alkalic unit), pegmatites and late crosscutting alkaline dikes. The rocks strike northwest and dip 45 to 65 degrees southwest. The alkaline overprinting is characterized by the presence of aegirine-augite and rare earth element-bearing minerals. Monazite is common in the area. The alkalic dikes appear to parallel the attitude of the host units, which strike 320 degrees and dip 55 degrees southwest. These dikes contain minor chalcopyrite, pyrite, malachite and magnetite.

A sample (UG-7813) from the altered rocks assayed 0.13 per cent lanthanum, 0.27 per cent cerium, and 0.1 per cent neodymium. A sample (UG-7816) from a dike assayed 0.23 per cent lanthanum, 0.42 per cent cerium and 0.15 per cent neodymium (Assessment Report 17872). A radioactive sample (UG-38M) of aegirine augite monzodiorite assayed 0.13 per cent thorium (Property File - Halleran, 1989).

In 1988, Chevron Minerals completed a program of rock and soil sampling, geological mapping and a 2.7 line-kilometre ground scintillometer survey. During 2006 through 2011, Paget Minerals completed programs rock and silt sampling, geological mapping and a combined airborne magnetic and radiometric survey, totalling 564.4 line-kilometres, on the area as the Mount Bison property.
