Comments on the geologic information

  • Geologic Description = Quartz vein cuts Late Cretaceous massive graywacke and minor slate of the Valdez Group. The quartz vein is up to 3 ft thick, strikes N 10 E, and dips 10 W. The vein can be traced for 150 ft and contains large quartz crystals, arsenopyrite, and gold. Assays indicate 0.63 oz/ton Au (Johnson, 1914).
  • Age = Late Cretaceous or younger; vein cuts massive graywackes and minor slates of the Late Cretaceous Valdez Group.
