Comments on the geologic information

  • Geologic Description = By late 1912, a 30-foot shaft had been sunk on a 2.5-foot-wide shear zone which assayed 26 ounces of silver per ton. Smith (1913, B 525) indicated the Schaefer prospect consisted of a flat-lying quartz-rich zone along which a 150 foot adit had been driven by 1912. The adit trends N 5 E in highly oxidized and weathered schist. It is believed the Schaefer adit was being driven to access the high grade silver mineralization encountered in the 30 foot shaft.
