Host rocks consist of Lower Jurassic Hazelton Group volcanics (Nilkitkwa Formation) comprised of andesitic flows with associated red and green tuffs and flow breccia. A mineralized vein crosscuts the volcanics striking 045 degrees and dipping 65 degrees southeast and extends across Trade Dollar No. 2 and 3, Cee and Second Glacier claims. According to Lay in 1928, the mineralized band of rock shows good chalcopyrite mineralization with associated galena and sphalerite.
