Comments on the geologic information

  • Geologic Description = Angular grains 0.1 to 0.8 millimeters across of cassiterite observed in thin section from in the Kekiktuk Conglomerate. Some cassiterite could still be present in contact zones of Romanzov Mountains granite, or in greisens and pyritic zones in the granite.
  • Age = Placer is Early Mississippian in age and lode from which the placer was likely derived is likely Early Devonian in age.
