The showing is underlain by Lower Jurassic Hazelton Group volcanics comprised mainly of andesite, tuff and flow breccia. On the Manitoba claim, at 1536 metres elevation, there is a mineralized vein hosting sphalerite, arsenopyrite and minor galena. A selected sample from the trench in 1929 assayed 13.03 grams per tonne gold, 130.28 grams per tonne silver, and 6.2 per cent zinc (Minister of Mines Annual Report 1929, page 163).
