Iron Creek has been identified as an indicated resource of about 6,000 tons of Co and 13,000 tons of Cu. The deposit consists of a shallow Co-Cu zone and a deeper Co-dominated zone with minor Cu. At Iron Creek, mineralization occurs as stratabound sulfide-rich zones within argillite-siltite and quartzite metasedimentary units in the Apple Creek Formation of the Belt-Purcell Supergroup. The sulfide-rich mineralization forms disseminations, massive lenses, stringers, and local shear and breccia zones. The ore mineralogy consists of chalcopyrite, cobaltiferous pyrite, magnetite, pyrite and arsenopyrite, with minor sphalerite veins.
