Comments on the geologic information

  • Geologic Description = Float sample of altered Jurassic granitic rock contained pyrite and malachite. Analysis of the float sample yielded 0.1 ppm Au, 2,000 ppm Cu, and 10 ppm Pb (Miller and others, 1978).
  • Age = Jurassic or younger, mineralization is hosted by altered granitic rocks of Jurassic age.
  • Age = Host rock is Jurassic.
