Comments on the geologic information

  • Geologic Description = The country rocks in the area of the Copper Kitty prospect are a tectonically mixed assemblage of Upper Devonian serpentinite, and subordinate basalt, chert, and gabbro. The deposit reportedly consists of pods of unspecified sulfide minerals, locally containing copper, gold(?) and silver (Balen, 1990: OFR 34-90). The hostrocks of the sulfide minerals also are not specified. Chromite apparently also occurs, presumably as magmatic segregations in the ultramafic rocks.
  • Age = the (presumed) magmatic segregation are syngenetic with the Upper Devonian ultramafic host rocks.
