Pyrite and minor chalcopyrite in quartz stringers occur along a fault contact between hornblende diorite of the Early to Middle Jurassic Island Plutonic Suite and Lower Jurassic Bonanza Group volcanic rocks. The 30 centimetre fault strikes 130 degrees and dips 85 degrees northeast. A 1.5 metre chip sample of the footwall in diorite assayed 2.9 grams per tonne gold and 1.714 grams per tonne silver (Assessment Report 14470).

An old adit occurs in the area and an 1895 report documented free gold with galena in altered diabase. Alteration minerals are quartz, pyrite and calcite.
