At the Sage 9 showing, chalcopyrite and bornite are disseminated within Helikian Grinnell Formation quartzites and are locally concentrated along the margins of diorite sills of the Proterozoic Moyie Intrusions. Malachite is common on weathered surfaces. Chalcopyrite and bornite are common in veinlets within quartzites and with specularite in fractures in diorites.
