"Bedrock samples were collected from the Broken Hammer Cu-Ni-PGE-Au deposit and surrounding host lithologies by the Geological Survey of Canada (GSC) to determine which indicator minerals are indicative of this deposit type. The deposit is known for world-class sperrylite crystals that are as large as 15 mm. The bedrock samples were processed using a combination of crushing, tabling, and heavy liquid separation to produce heavy mineral (>3.2 specific gravity) concentrates, which were then visually examined under binocular microscope. Ore minerals recovered from the mineralized samples include sperrylite (up to 2 mm in size), michenerite, tellurobismuthite, kotulskite, and merenskyite, as well as gold and chalcopyrite.
