Comments on the geologic information

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