    Dip NW
    Width 1.5M

Controls for ore emplacement

  • Quart Vein Fault Zone

Comments on the geologic information

  • THE MINE WAS OPENED IN QUARTZ VEINS ENCLOSED BY FINE GRAINED, DEEP GREEN, ANDESITE. IN MOST PLACES NEAR THE QUARTZ VEINS, THE ANDESITE HAS BEEN SHEARED TO CHLORITE-SERICITE PHYLLITE. COMMONLY, FRAGMENTS OF PHYLLITE ARE IN THE VEIN QUARTZ. SILICIFIED PHYLLITE AT THE BLUE SHAFT CONTAINED GALENA, SPHALERITE AND PYRITE WITH MINOR CHALCOPYRITE INTERGROWN WITH PYRITE. WEATHERED SURFACES OF SOME ROCKS WERE COATED WITH MALACHITE.u OPEN VUGS OCCUR IN THE QUARTZ VEIN. SOME ORE IS CONTAINED WITHIN AN 8 CM THICK CALCITE-RICH ZONE WITHIN 1.5 M THICK QUARTZu VEIN.
