Comments on the geologic information

  • Geologic Description = Johnson (1914) reported a shattered felsic dike, 60 to 67 inches wide, is cemented by quartz stringers up to 8 inches wide that carry gold, arsenopyrite, galena, and pyrite. The felsic dike is Tertiary in age, and strikes N 50 E, and dips 53-75 W. A nearby 3 ft wide quartz vein strikes N 51 W with a 60 E dip, and contains gold, arsenopyrite, galena, and pyrite in a quartz-calcite gangue. Samples from the dike contain as much as 0.34 oz/ton Au (Johnson, 1914). The felsic dike cuts metasedimentary rocks of the Valdez Group.
  • Age = Tertiary or younger; vein cuts a shattered Tertiary felsic dike.
