The area is underlain by biotite granite and pegmatite of the Cretaceous Baldy Batholith. Later phase aplite dykes are common and occasional zones of hydrothermal alteration are present.
Fracture controlled, very fine-grained sulphide mineralization occurs in the granite. A rock sample assayed 48.3 grams per tonne silver, 0.14 per cent molybdenum, 0.19 per cent lead and 0.05 per cent tungsten (Assessment Report 14262).
