Comments on the geologic information

  • Geologic Description = The mineralization is within a brecciated shear zone of Cretaceous Valdez Group greenstone (Tysdal and Case, 1979). The cement of the breccia is composed of quartz, calcite, sphalerite, pyrite, epidote, and chalcopyrite. A tunnel, 35 feet long, has been run along a shear zone that strikes N32W and dips 68 W. About 200 feet southwest of this tunnel another shear occurs which has been drifted on for about 35 feet. This zone is about six feet wide and strikes N12W with a vertical dip (Martin and others, 1915). No assay results are reported for this prospect.
  • Age = Cretaceous or younger; breccia zone in Cretaceous greenstone.
