Comments on the geologic information

  • Geologic Description = Occurrence is a very small area of strong epidote - quartz - magnetite - chalcopyrite veining within 0.9 m of the contact of Tertiary andesite porphyry breccia with fine-grained metasedimentary rocks. Resource Associates of Alaska (1976) report two rock samples taken near the metasediment-volcanic contact yielded values as high as 11.2 ppm Ag, 1,100 ppm Cu, 180 ppm Pb, and 680 ppm Zn. One nearby stream sediment sample showed slight anomaly (109 ppm Cu). However, these results could not be reproduced by Nelson and others (1985).
  • Age = Tertiary or younger, based on geologic relationships.
