The Lorindale occurrence is underlain by amygdaloidal basalt of the Upper Triassic Karmutsen Formation (Vancouver Group) cut by a fault. Quartz veining occurs within fracture zones. Mineralization consists of local native gold and minor amounts of chalcopyrite and pyrite with silver values.

Past workings include an adit and shaft developed on one of three quartz veins ranging from a few to 40 centimetres in width.
