Comments on the geologic information

  • Geologic Description = According to Jansons and others (1984), quartz veins and stringers up to 1 ft wide are found in a well developed shear zone in hornelsed Late Cretaceous metasedimentary rocks of the Valdez Group. The zone is about 12 ft wide along the contact of a 50 ft felsic dike with the Valdez Group rocks. Disseminated grains and massive pods of pyrite, with lesser arsenopyrite and chalcopyrite present.? Six samples contained up to 0.005 oz/ton Au and up to 0.05 oz/ton Ag (Jansons and others, 1984).
  • Age = Late Cretaceous or younger; shear zone cuts metasedimentary rocks of the Late Cretaceous Valdez Group.

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 = Development limited to a 15 ft long adit. Jansons and others (1984) reported six samples contained up to 0.005 oz/ton Au and up to 0.05 oz/ton Ag, thus site has low potential for mineral development.
