Comments on the geologic information

  • Geologic Description = This occurrence consists of pyrite- and chalcopyrite-bearing quartz veins as much as 3 feet thick (Miller and Ferrians, 1968). The veins cut Jurassic-Cretaceous meta-andesite north of the contact with the Cretaceous Zane Hills pluton. Grab samples contained 0.5% Cu and 0.6 ppm Au.
  • Age = Jurassic-Cretaceous or younger.
