Andesitic flows and interbedded chert of the Jurassic Hazelton Group are cut by a north trending diorite dyke and a north-northeast trending fault. A quartz vein, about 100 metres long and 20 centi- metres wide, follows the fault which strikes 020 degrees and dips 75 degrees east. The vein contains veinlets of argentite and minor chalcopyrite. A 0.9 kilogram sample of selected ore assayed 4210 grams per tonne silver and 0.7 grams per tonne gold and a representa- tive sample from an old ore bin assayed 1222 grams per tonne silver, 0.7 grams per tonne gold and 0.20 per cent copper (Geological Survey of Canada Memoir 212).
