Economic information

Comments on the geologic information

  • Geologic Description = Three, quartz-pyrite veins intrude Cretacous Valdez Group graywacke and slate (MacKevett and Holloway, 1977). The veins are 2 to 6 feet thick. Martin and others (1915) visited one of the veins that strikes N27E and dips 40W. It was 71 inches thick and contained pyrite, chalcopyrite, and graphite. No assay results are reported.
  • Age = Cretaceous or younger; the veins cut Cretaceous graywacke.
