The Jane 2 occurrence is located immediately northwest of Breen Lake, approximately 3 kilometres west of Crofton.

The area is underlain by east-northeast striking, steeply dipping, andesitic and rhyolitic volcanics and volcaniclastics of the Upper Devonian McLaughlin Ridge Formation (Sicker Group). Large irregular gabbroic bodies (informally known as the Mount Hall gabbro), coeval with the Upper Triassic Karmutsen Formation (Sicker Group), intrude the volcanics. Also intruding the stratigraphy are quartz-feldspar porphyry bodies of the Late Devonian Saltspring Intrusive Suite (formerly the Saltspring Intrusions).

Locally, fine to medium grained massive pyrite and chalcopyrite are exposed over 1 square metre. The massive sulphides are hosted in chlorite rich sandy to ash tuff, which is cross cut by abundant stock work pyrite and chalcopyrite, and associated zones of silicification.

In 2010, Westridge Resources completed a program of geological mapping and geochemical sampling on the Breen Lake area. Grab samples of massive sulphide mineralization assayed up to 4.26 per cent copper and 12.1 grams per tonne silver (Assessment Report 31677).
