The area is mainly underlain by the Jurassic Hazelton Group volcanics which has been intruded by plutonic rocks. The occurrence is associated with an Eocene granodiorite intrusion.

Mineralization consists of pyrite, chalcopyrite, molybdenite and minor pyrrhotite. Pyrite, chalcopyrite and pyrrhotite generally occur as disseminations although locally, they are found along fractures and quartz veinlets. Molybdenite generally occurs in quartz veinlets and only rarely as disseminations.
