Comments on the geologic information

  • Geologic Description = The site of an isolated sample of chalcopyrite-bearing quartz float with malachite that contained 49 ppm gold, 74 ppm silver, and 1% copper. (Still and others, 1984). It occurs within a Cretaceous diorite (MacKevett and others, 1974) but may be associated with a small pendant within the diorite, like SK053 or SK052.
  • Age = Probably Cretaceous or younger, based on the age of the surrounding diorite (MacKevett and others, 1974).
