The claims are underlain by a Late Cretaceous quartz monzonite stock which intrudes both Lower Jurassic Hazelton Group volcanics and Lower Cretaceous Skeena Group sediments. The contact aureole is intensely silicified and is weakly mineralized with pyrite.

Mineralization occurs in a small network of quartz veinlets which host pyrite and silver bearing galena. Old workings at the Cabin location show quartz veins with arsenopyrite. The network of quartz veins crosscut banded, slatey argillite and host minor occurrences of pyrite, galena, and possibly sphalerite.
