Comments on the geologic information

  • Geologic Description = The Moonlight prospect is a vein of crushed quartz and schist, less than one foot wide, in a fracture zone in quartzite schist and granite. The vein is said to carry considerable gold and large amounts of unspecified sulfides (Smith, 1913; B 525, p. 201). The vein was traced by prospect pits for 2500 feet. It strikes N 70 W and dips steeply NE (Chapin, 1914, p. 349). Grab samples of ore on dump contained 0.16 ounces per ton in gold (Hill, 1933, p. 114). There were about 170 feet of underground workings by 1914 (Chapin, 1914).
