The area is underlain by quartz diorite of the northern part of the Cretaceous to Tertiary Ecstall pluton. Quartz veins with auriferous pyrite and chalcopyrite lenses are associated with pegmatite and aplite dykes. Erratic mineralization occurs along a 60.0 metre, northwest strike, dipping about 15 degrees northeast. A composite sample of a 1.5 by 0.4 metre lens, assayed 8.2 grams per tonne gold, 51.4 grams per tonne silver and 4.4 per cent copper (Minister of Mines Annual Report 1934).
