CANMET-UMT-1 is a sample of mill tailings from the nickel-copper Giant Mascot Mines, Hope, British Columbia. UMT-1 is composed almost entirely of silicates including pyroxene (enstatite), amphibole (tremolite) and chlorite. Ore minerals comprise a minor portion of the tailings, and include magnetite, ilmenite, goethite and some iron, magnesium, aluminum and magnesium spinels. Both sulphide species present, pentlandite and chalcopyrite, occur as liberated grains and as small inclusions in the silicates.
