Economic information

Comments on the geologic information

  • Geologic Description = Upper Healy Creek drains an area underlain by Birch Creek Schist cut by Mesozoic to Tertiary granites. Lower Healy Creek drains Eocene to Miocene sandstone, claystone and subituminous coal (Wilson and others, 1998), unconformably overlain by gold-bearing Miocene gravels. The auriferous gravels are the likely source of placer gold in Healy Creek.
  • Age = Quaternary.
