Pods of bornite, chalcopyrite and minor chalcocite are found with epidote, tremolite, chlorite, magnetite, minor garnet and woll- astonite in green volcanics of the Lower Jurassic Hazelton Group (Telkwa Formation). The volcanics are intruded by the Eocene Nanika Intrusions (quartz monzonite, felsite partly porphyritic).
