The Maple Mountain occurrence is located on the north western flank of Maple Mountain, approximately 2.5 kilometres south east of Crofton.

Thearea is underlain by basaltic andesites of the Devonian Nitinat Formation, Sicker Group. These are intruded by gabbroic rock (informally called 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 the Saltspring Intrusions), (Massey, N.W.D., Personal Communication, 1991).

Locally, a massive, milky white quartz vein occurring on the northwest flank of Maple Mountain contains 1 per cent disseminated chalcopyrite.

In 1985, Canamax Resources completed a program of soil geochemical sampling on the area as the Croft 1 claim. In 1986 and 1987, the area was explored as the PF claims. Programs of geological mapping, prospecting and geochemical sampling were completed at this time. A grab sample assayed 0.35 per cent copper (Assessment Report 16029, page 14).

In 2007, Maple Mountain Explorations Inc. completed a program of rock and soil sampling. This work identified a rock cut exposure, on the M-120 logging road, of massive pyrite mineralization in layered greenstone with epidote alteration. Samples assayed low in metal values.
