Comments on the geologic information

  • Geologic Description = This prospect is a vuggy, oxidized quartz vein that strikes N 38 E and has a strike length of approximately 500 feet (Wilson and others, 1988). It occurs in volcanic rocks of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). The vein is exposed in a short adit and may be the southwestern continuation of the Sitka fracture system (Wilson and others, 1988). Sulfides present in the vein include chalcopyrite, galena, pyrite, and sphalerite.
  • Age = Eocene or younger.
