The area is underlain by pyritic, graphitic schists, or a Permo- Triassic unnamed formation striking north-northwest and dipping 45 degrees east. Several shear zones with quartz veins carrying pyrr- hotite and minor chalcopyrite occur in the schists. The veins are 1 to 2 metres wide and a 1.2 metre sample of a vein assayed 75.4 grams per tonne silver and an estimated 0.7 grams per tonne gold (Minister of Mines, Annual Report 1928-70).
