A skarn type deposit of more or less solid chalcopyrite fills a fissure in a shear zone that cuts granodiorite of the Lower Jurassic Island Plutonic Suite. Contact with limestone of the Quatsino Formation, Vancouver Group occurs about 800 metres away. The fissure is lenticular in shape, being 1.8 metres wide, 9 metres long and 4.6 metres deep. A similar lens of chalcopyrite occurs about 10 metres higher up the mountain and about 15 metres to the northeast.

Development work on the lower showing consisted of a crosscut adit about 21 metres long, an opencut 9 by 4 by 4.6 metres and several trenches and other shallow opencuts. About 68 tonnes of chalcopyrite ore was awaiting shipment on the dump in 1918. A sample of the material taken from the dump contained 7.2 per cent copper with traces of gold and silver (Minister of Mines Annual Report 1916). Little work was done on the lens found at higher elevation.
