Comments on the geologic information

  • Geologic Description = Gold occurs in a 20-foot-wide quartz porphyry dike that strikes N 30 W and dips 45 SW. This dike was exposed by a tunnel driven 50 feet through schist. The dump material on the Central Star shaft is composed mainly of schist but contains some fragments of quartz porphyry (Hill, 1933, p. 118). In 1909, this shaft was 65 feet deep (Prindle, 1910).
