Mineralization occurs within sediments and volcanics of the Upper Triassic Stuhini Group. The most significant, the Frosty showing, consists of several east trending chloritic shear zones exposed for 200 metres along the banks of West Middle Creek. The shear zones vary in width from 0.3 to 1.5 metres and contain pyrite and chalcopyrite. A 30-centimetre sample assayed 1.54 grams per tonne gold, 9.6 grams per tonne silver and 1.79 per cent copper (Assessment Report 21110). Pass Lake Resources Ltd held the property as the Rattle and Roll claims in 1990 and 1991.
