Comments on the geologic information

  • Geologic Description = Gold was discovered on Dewey Creek by 1900; it was in 3 feet of auriferous gravel on a sandy clay layer overlain by 1 foot of sandy blue clay and 1 foot of muck. The gold is accompanied by considerable scheelite and garnet and some magnetite (Brooks and others, 1901). Some mining apparently took place in 1903 (Collier and others, 1908). Dewey Creek is near the northeast extension of the Anvil fault; this fault juxtaposes massive marble against marble and schist in this area. These rocks may in part correlate with the Casadepaga Schist (Hummel, 1962 [MF 247]; Bundtzen and others, 1994). Locally, the Anvil Creek fault is a mineralized structure (for example, NM234) containing stibnite and possibly gold.
  • Age = Quaternary.
