The area is underlain by quartz monzonite of the Cretaceous to Tertiary Coast Plutonic Complex. Andesite, aplite and diorite dykes cut the quartz monzonite. Molybdenite mineralization occurs in quartz veins and disseminated in the country rock. The veins are up to 10 centimetres wide and also contain pyrite, magnetite and minor chalcopyrite. A chip sample assayed 0.27 per cent molybdenum, 0.027 per cent copper and 0.6 grams per tonne silver (Assessment Report 9423).

North trending faults show normal displacement and may be related to molybdenite mineralization.
