Comments on the geologic information

  • Deposits in this small district were compared to "red bed" deposits in New Mexico and Arizona by Lindgren (1908). Copper occurs as chalcocite and copper oxides (mainly malachite) in mostly Pennsylvanian-age clastic rocks. The Cotopaxi Fault bounds the eastern margin of the block of Paleozoic sediments in this area. Proterozoic rocks are exposed east of the fault.
  • One known deposit, the Indian Springs Gulch prospect, is lumped into the Red Gulch district although it is in Proterozoic rocks.
