Economic information

Comments on the geologic information

  • Geologic Description = This occurrence is in tuff mapped as part of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). Two rock samples of silicified andesitic tuff collected by the U.S. Geological Survey in the mid-1980's were reported to be anomalous in gold and lead (Wilson and others, 1988).
  • Age = Eocene or younger.
