The area is underlain by well foliated micaceous quartz- feldspar-biotite schist and gneiss of the Shuswap Metamorphic Complex. These rocks are intruded by or in fault contact with irregular bodies, dykes and sills of biotite-rich granodiorite.

Minor molybdenite mineralization occurs in well fractured micaceous schist in contact with the intrusive. Minor pyrrhotite and pyrite are disseminated in the schists.
