Comments on the geologic information

  • Geologic Description = Still and others (1991) describe this prospect as a 10-foot-long adit driven along a pyrite-bearing shear zone in limestone. Samples from the adit and its vicinity contained up to 0.59 ppm gold, 3 ppm silver, 1,100 ppm zinc, 550 ppm copper, and 140 ppm lead. The limestone unit is Paleozoic (MacKevett and others, 1974) possibly, Late Pennsylvanian or Early Permian (Eakin, 1919).
  • Age = Probably Late Paleozoic or younger based on the age of the limestone (MacKevett and others, 1974; Eakin, 1919).
