The property is underlain by greywackes of the Gowganda Fm intruded by Nipissing gabbro. Gold-bearing quartz veins are associated with a broad zone of soda, potassium, chlorite and carbonate alteration or with carbonate alteration within the gabbro. There were two east-trending quartz veins along which 5 shafts were sunk. The quartz veins occur at the contact between arkose and greywacke.
