Comments on the geologic information

  • Geologic Description = Color anomaly in Unalaska Formation (see Drewes and others, 1961) near contact with diorite(?). Anomaly is a zone containing 2 percent sulfides, 500 feet (150m) by 2000 feet (600 m) in size, elongate to the northwest. Sulfides are dominantly pyrite with traces of chalcopyrite. There appeared to be no structural control on stronger alteration and mineralization.
