Location: Teller County, Alaska, United States, North America
Lat / long: 65.45127, -167.1724
dep_id: 10308735
Commodity type: metallic and nonmetallic
Major mineral: Silver, Beryllium, Copper, Fluorine-Fluorite, Lead, Tin, Zinc
Operation type: Unknown
Development status: Prospect
ore: Cassiterite, Chrysoberyl, Fluorite, Galena, Sphalerite, Stannite
gangue: Arsenopyrite, Diaspore, Pyrite, Tourmaline
alteration: The veining and related replacement in this area can be thought of as distal alteration to more intense, tin metallization at depth. Mass balance calculations show significant SiO2, Al2O3, alkali, and fluorine enrichment with this type of alteration (Sainsbury, 1968, p. 1567).
