Jurassic Hazelton Group volcanics are intruded by a pyroxene quartz diorite stock of the Cretaceous to Tertiary Coast Plutonic Complex. A 0.6 to 1.2 metre wide quartz vein occurs along the contact between green andesites and red andesites of the Hazelton Group. The vein is mineralized with minor galena, pyrite, and chalcopyrite. A 0.8 metre sample across the vein assayed 343 grams per tonne silver, 4.1 grams per tonne gold, and 0.5 per cent copper (Minister of Mines Annual Report 1917).
