The West 2 occurrence is located immediately south of Crofton Lake.

The area is underlain by trachyte, and minor areas of argillite and quartz mica schist of the Upper Devonian McLaughlin Ridge Formation (Sicker Group). The strata is intruded by gabbroic rock (informally known as the Mount Hall Gabbro), coeval with the Upper Triassic Karmutsen Formation (Vancouver Group), and by quartz-feldspar porphyry of the Late Devonian Saltspring Intrusive Suite (formerly called the Saltspring Intrusions), (Massey, N.W.D., Personal Communication, 1991).

Chalcopyrite was noted as disseminations near the contacts of the sediments and trachyte, and in quartz veins up to 50 centimetres in width cutting the trachyte and sediments.

In 1969, Canpac Minerals explored the area as the Sirius claims. A program of geological mapping and a ground magnetic survey was completed. In 1978, the area was staked as the Croft 2 claim and a program of geological mapping and soil sampling was completed. In 1983, the area was staked as the West claims by R.J. Bilquist and a program of prospecting was completed. In 1984 and 1985, Falconbridge optioned the property and completed programs of geochemical sampling and an airborne geophysical survey. In 1987, Falconbridge completed a drilling program of 10 holes, totalling 3170.7 metres, in the vicinity of Breen Lake on the West 1 claim.
