Comments on the geologic information

  • Geologic Description = A gossan-rich, sheeted quartz vein in hornfels has been explored by a now-caved adit at this location. Euhedral quartz crystals are well-developed in the vein. A sample contained 250 ppb gold, 250 ppm arsenic, and 62 ppm yin (Bundtzen and Laird, 1991). The prospect is within about 300 feet of the southern contact of the Russian Mountains intrusive complex.
  • Age = Late Cretaceous or Tertiary. Veins post-date hornfels developed around the intrusive complex of the Russian Mountains. Quartz monzonite from this complex has yielded a K/Ar age of 70.3 +/- 2.1 Ma (Bundtzen and Laird, 1991).
