Economic information

Comments on the geologic information

  • Geologic Description = The country rocks in the area of this prospect are Upper Triassic, carbonaceous, calcareous shale, argillite, sandstone, and siltstone. This sequence is cut by dikes, sills, and plugs altered diabase and gabbro (Wilson and others, 1998). The deposit presumably consists of auriferous chalcopyrite and possibly other sulfides, disseminated in the sedimentary and (or) intrusive rocks.
  • Age = Late Triassic or younger.
