Skarn mineralization is developed within an Upper Triassic limestone unit and volcanic derived sediments of the Upper Triassic Stuhini Group adjacent to a Jurassic and/or Cretaceous hornblende diorite stock, 1.6 kilometres in diameter. Chalcopyrite, pyrite, pyrrhotite, magnetite and specular hematite are observed in outcrop.
