Comments on the geologic information

  • Geologic Description = Mineralization is in form of disseminations and fracture fillings of pyrite and chalcopyrite in strongly iron-stained intermediate volcanics and in the neighboring hypabyssal granitic to granodioritic intrusives near contact of Tertiary granitic rocks and Tertiary volcanic rocks. Interpreted by Resource Associates of Alaska (1976) as a volcanic neck or breccia pipe, composed of highly fractured, silicified, and recrystallized volcanic rocks. Resource Associates of Alaska (1976) reported a nearby stream sediment sample with value of 1,200 ppm Cu.
  • Age = Tertiary or younger.
