Comments on the geologic information

  • Geologic Description = North striking quartz veins found in Late Cretaceous Valdez Group graywacke and slate. The vein, 6 to 69 inches thick, can be traced for 200 ft and contains gold, galena, pyrite, and chalcopyrite. The primary vein is intersected by another quartz vein, approximately 4 ft thick (Johnson, 1914). Jansons and others (1984) reported traces of gold and up to 0.25 oz/ton Ag in samples.
  • Age = Late Cretaceous or younger; veins cut Late Cretaceous Valdez Group graywackes and slates.

Economic information about the deposit and operations

Development status Prospect
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Prince William Sound

Comments on the production information

  • Production Notes = No reported production.

Comments on the workings information

  • Workings / Exploration = Surface stripping was the only development at the time of the visit of Johnson (1914). Jansons and others (1984) report traces of gold and up to .0.25 oz/ton Ag found in the three samples that were taken. Low mineral development potential.
