The claims are underlain by Lower Jurassic Hazelton Group vol- canics comprised of andesitic to dacitic pyroclastics which trend northeast. The Hazelton rocks are overlain by Lower Cretaceous Skeena Group argillaceous to quartzitic cherty sediments. The host rocks are intruded by a Late Cretaceous to Eocene quartz diorite stock which trends northeast. The intrusive is exposed on the claims and measured approximately 245 by 425 metres.

Disseminated pyrite occurs in all of the rock types. Minor arsenopyrite occurs in the ankeritized sediments and related quartz- carbonate fractures.

The quartz diorite intrusion hosts minor chalcopyrite, pyrite and molybdenite in hairline fractures, quartz veinlets, aplitic veins and along the joints within the stock.
