The claims are underlain by Lower Jurassic Hazelton Group vol- canics comprised of andesitic to rhyolitic flows, tuffs and breccia. On the Cariboo, a fissure vein 1.8 metres wide host mineralization and strikes 310 degrees. At 1722 metres elevation, a brecciated fault fissure strikes 345 degrees. The quartz vein filling ranges from 15 to 30 centimetres and hosts sphalerite, chalcopyrite and iron oxides. In 1911, a sample assayed 2.7 grams per tonne gold, 277.7 grams per tonne silver, and 2.1 per cent lead. Another sample taken from this fissure at a higher elevation assayed 2.7 grams per tonne gold, 178.6 grams per tonne silver, 3.2 per cent lead and 0.75 per cent copper (Minister of Mines Annual Report 1911, page 119).
