Upper Triassic Karmutsen Formation (Vancouver Group) greenstones are in fault contact with Jurassic to Triassic Kunga Group rocks comprised of grey massive and black bedded limestones (Sadler and Peril formations) and thin-bedded limy argillites (Sandilands Formation).

Two gold showings, about 150 metres apart, occur within sheared, chloritic and partially silicified Karmutsen volcanics. Mineralization consists of disseminated arsenopyrite and pyrite, accompanied by minor quartz veining. The No. 2 showing of occurrence 103B 066 lies about 520 metres to the southeast.

A 0.5-metre chip sample of arsenopyrite-pyrite mineralization from the northern most of the two showings (No. 4 showing), assayed 5.76 grams per tonne gold (Assessment Report 17097, sample 6661). A second sample consisting of 0.25 metre of quartz vein assayed 25.8 grams per tonne gold (sample 6658). A 1.8-metre chip sample from the southern (No. 5) showing assayed 5.0 grams per tonne gold (sample 6610).
