Comments on the geologic information

  • Geologic Description = This chromite occurrence, one of several within the Halibut Bay ultramafic complex, consists of a zone of disseminated grains and bands or stringers of chromite. The zone, inferred to measure 150 by 6 feet and to have inferred depth of 38 feet, constitutes an inferred resource of approximately 4000 tons of rock containing an estimated 6 percent chromite (Foley and Barker, 1985, table 13). A chip sample across 6 feet assayed 120 ppm cobalt, 3.8 percent chrome, 640 ppm copper, 120 ppm nickel, and trace amounts of platinum and palladium (Foley and Barker, 1985, table 14). ? the Halibut Bay ultramafic complex, consisting mostly of dunite, gabbro, pyroxenite, and peridotite, occurs within sedimentary units of the Uyak formation of Cretaceous age
