Economic information

Comments on the geologic information

  • Geologic Description = Color anomaly 1,500 by 5,000 ft (450 by 1,500 m) in size in volcanic and epiclastic rocks intruded by diorite and quartz porphyry(?). Anomaly is elongate, oriented N 20x E.
  • Age = Miocene 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 one silt sample which was barren. It does not appear occurrence has been adequately examined for epithermal gold vein potential.
