Albite diorite of the Cretaceous to Tertiary Legate Creek apophysis intrudes Jurassic Hazelton volcanics. Several northwest, 45 to 70 degrees southwest dipping quartz veins occur along shears in the diorite over a distance of 300 metres. The veins are 0.15 to 3 metres wide and contain sparse disseminations of pyrite, galena, tetrahedrite, chalcopyrite, galena and specularite. The upper vein is cut by a northeast trending, 40 degree southeast dipping fault, which also terminates quartz veins to the west. A 76 centimetre channel sample across the upper vein assayed 0.7 grams per tonne gold, 134 grams per tonne silver, 0.36 per cent copper and 0.82 per cent lead (Geological Survey of Canada Memoir 212).
