Comments on the geologic information

  • Geologic Description = The Thompson prospect is a vein or fault-controlled occurrence containing zinc and antimony minerals (Hummel, 1975) that are assumed to be sphalerite and stibnite. The prospect is near or at the upper contact of calcareous schist with a marble layer; the rocks strike northwest and dip northeast (Hummel, 1962 [MF 248]). The Thompson prospect is one of several of diverse type and metal content in the general vicinity of Rocky Mountain Creek, Nelson Gulch, and Christian Creek.
  • Age = Probably mid-Cretaceous or younger if a vein occurrence.
