Economic information

Comments on the geologic information

  • Geologic Description = Christie (1974) reports a 3,000 by 3,000+ ft (900 by 900+ m), elongate to the northeast, color anomaly in volcanic rocks, mainly breccia and flows(?). His interpretation was that alteration was solfataric. No signs of fracture-controlled mineralization, epidote, or intrusive rocks.
  • Age = Pliocene or younger

Economic information about the deposit and operations

Development status Occurrence
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Alaska Peninsula

Comments on the workings information

  • Workings / Exploration = Brief reconnaissance geologic mapping and collection of a few silt samples reported by Christie (1974). Silver to 1.4 ppm and zinc to 99 ppm; otherwise background levels for copper, molybdenum, and gold.
