The property is underlain by phyllites, carbonates, argillites, volcanic flow rocks and minor quartzites of probable Lower Paleozoic Lardeau Group. The rocks are variously hornfelsed.

The metasediments and metavolcanics are intruded by a quartz monzonite pluton of Cretaceous (?) age. Massive garnet-diopside skarn is developed along the contact of the pluton. The skarn occurs as a conformable replacement along the base of marble units.

Several lead and zinc vein and replacement showings exist in the area.
