Comments on the geologic information

  • Geologic Description = Hummel (1962 [MF 248]) identified the Lindfors prospect as an antimony occurrence. The ore mineral is assumed to be stibnite, possibly with quartz and some gold values, in veins that cross-cut metasedimentary rocks. The prospect is in calcareous schist about 200 feet structurally below an intercalated massive marble (Hummel, 1962 [MF 248]).
  • Age = Probably mid-Cretaceous or younger if a vein occurrence.

Comments on the workings information

  • Workings / Exploration = The Rocky Mountain Creek area was prospected for scheelite and other strategic minerals during World War II. Various prospects along the creek were described by Coats (1944) and by Anderson (1947). Some exploration pits or trenches are probably present.
