The Granite Creek occurrence is located about 3 kilometre east of the South Unuk River and 2 kilometres north of Divelbliss Creek. The area is underlain by the northwest trending contact of the Lower Jurassic Betty Creek Formation (Hazelton Group) conisting of andesitic volcanics and the Upper Triassic Stuhini Group (on the west) comprised of marine sedimentary and volcanic rocks.

Traces of copper mineralization are reported to occur in an area of amphibolitic rock just east of the cataclasite zone. Copper stains (malachite) were also observed in rock less than a kilometre to the southwest (Property File (Geology Map - 1:31,250 scale - Newmont Exploration of Canada Ltd., 1960s)).

Other the the Newmont documentation no investigation of the showing is documented. The area is contained within the Corey property of Eskay Creek Mining Corp. See Cumberland (104B 011) for details of the Corey property.
