Comments on the workings information

  • MINE WORKINGS CONSIST OF 300 FEET SHAFT SUNK ON A SILICIFIED ZONE ALONG THE CONTACT BETWEEN MESOZOIC METAMORPHIC ROCKS AND A TERTIARY GRANODIORITE PORPHYRY. THE MINERALIZED ZONE STRIKES APPROX. N 80 DEG E. PYRITE AND OXIDATION PRODUCTS THEREOF OCCUR AS FINE DISSEMINATIONS IN A SILICEOUS GANGUE. MINE HAS BEEN IDLE FOR OVER 50 YEARS (BONHAM, P 78)
