Comments on the geologic information

  • Geologic Description = The prospect is a copper-bearing mineral occurrence contained within calcareous metasedimentary rocks (Hummel,1962 [MF 248]). It appears to be on the north or hanging wall side of the same fault structure that is adjacent to a nearby scheelite prospect (NM075). The prospect belongs to the same class of stratabound copper deposits as those at Copper Creek (NM053) and Copper Mountain (NM054) identified by Hummel (1975) as occurrences or prospects in silicified marble, that contain visible sulfide or other ore minerals.
  • Age = Late Proterozoic, early Paleozoic, or mid-Cretaceous.
