The north-northwest trending Hozameen fault separates Permian to Jurassic Hozameen Complex cherts, greenstones, argillites and limestone in the west, from Jurassic Ladner Group sediments to the east. A Late Cretaceous quartz diorite stock intrudes the Ladner Group along the east side of the Hozameen fault. The quartz diorite intrusion was dated by the Geological Survey of Canada at 84 million years using potassium-argon dating methods.

Shearing occurs within the quartz diorite intrusion. Molybdenite is found in tight vertical fractures. In 1927, a short tunnel was driven along a 1.8 metre shear zone in which chalcopyrite mineralization was noted. A sample taken across 36 centimetres assayed trace gold, 68.6 grams per tonne silver and 2.5 per cent copper (Minister of Mines Annual Report 1927, page 211).
