A minor past producer of nickel and bismuth, various attempts at exploration and mining date back to 1940.

"Mineralization occurs in fractures filled with quartz and carbonate within Archean metavolcanics and minor associated sediments of the Yellowknife Group and within granite dykes. Metallic minerals that have been reported are: niccolite, skutterudite, gersdorffite, rammelsbergite, annabergite, erythrite, arsenopyrite, native antimony, pyrite and chalcopyrite. The main zone, which occurs near the margin of a diabase dyke, is located across the SW limb of a conjugate fault system with the massive niccolite lens in a hanging-wall felsite-breccia along a minor NE striking fault."

"Mineralization appears to be associated particularly with bands of red granite which have been sheared and brecciated, and which have been veined or cemented by carbonate and lesser quartz. Niccolite, skutterudite, gersdorffite, rammelsbergite, arsenopyrite, pyrite and chalcopyrite occur in structurally controlled quartz-carbonate veins and vein breccias."
