Comments on the geologic information

  • Geologic Description = At this site a quartz vein striking N. 25 W. and dipping 40 southwest cuts Cretaceous schist or slate (Becker, 1898). The vein carries arsenopyrite, pyrite, and free gold and varies in thickness from a few inches to 6 feet, averaging 2 1/2 feet. Quartz stringers parallel to the main vein occur in the surrounding country rock. Acidic dikes occur in the vicinity. This vein may be on the same structure as the Dan (KD004).
  • Age = Cretaceous or younger
