The area is underlain by Upper Triassic Karmutsen Formation volcanic rocks of the Vancouver Group. These are interbedded with, and overlain to the northeast by a northwest trending belt of Quatsino Formation limestone (Vancouver Group) known historically as the "lime- belt". The Vancouver Group rocks are in fault and/or intrusive contact to the northeast with intrusive rocks of the Juro-Cretaceous Coast Plutonic Complex.

A pyritic quartz vein from 5 to 45 centimetres wide, strikes 160 degrees and dips 80 degrees. The vein cuts andesite and can be traced for about 100 metres. Two shafts, considerable open cutting, trenching and stripping were done on the prospect prior to 1911. A sample across 30 centimetres assayed 51.43 grams per tonne gold, 10.29 grams per tonne silver and 1 per cent zinc. Another sample over 30 centimetres assayed 926 grams per tonne gold and 103 grams per tonne silver (Minister of Mines Annual Report 1926).

A shear containing pyrite, pyrrhotite and traces of chalcopyrite were examined in 1984 (Assessment Report 12467).
