Comments on the geologic information

  • Geologic Description = By 1912, prospect pits revealed gold-bearing quartz rubble (Smith, 1913; B 525). A 15-foot vertical shaft was sunk on a 2-foot-wide shear zone in 1913; about 40 feet below the collar of the shaft, a 100-foot drift was driven parallel to the shear zone. A 20-foot cross-cut from this adit intersected a 5-inch-thick quartz stringer but failed to intersect the 2-foot-wide shear zone found on the surface (Chapin, 1914). Both the quartz stringers and the black carbonaceous schist host rock contained gold.
