The area is underlain by the Upper Triassic Vancouver Group, comprising Karmutsen Formation volcanics and Quatsino Formation limestone, and Lower Jurassic Bonanza Group volcanics. This assemblage is intruded by Jurassic Island Plutonic Suite.

Locally, magnetite and minor chalcopyrite in garnet-epidote- actinolite skarn with a maximum width of about 15 metres is exposed by open cuts over a 300-metre distance. The skarn is found at the top of a bank in a grey crystalline limestone unit overlain and underlain by Karmutsen Formation volcanics. This limestone is probably an intercalating lens within the upper part of the Karmutsen Formation.

Mineralization continues east, where chalcopyrite, sphalerite and galena are found in strongly silicified limestone.

Work History

The area has been explored in conjunction with the nearby Caledonia (L.1294) occurrence (092L 061) and a complete regional exploration history can be found there.
