Ore body information

  • General form VEINS AND SILICEOUS ZONES
    Strike N 40 E
    Dip 74 NW
    Thickness 0.5M
    Length 300M

Controls for ore emplacement

  • Siliceous Zones And Quartz Veins

Comments on the geologic information

  • THE MINE WAS OPENED IN QUARTZ VEINS ASSOCIATED WITH SILICEOUS ZONES. VEIN OF MILKY QUARTZ ARE IRON STAINED AND CONTAIN VUGS LINED WITH MANGANESE OXIDE. SHEARED PHYLLITE CROSSCUT BY VEINLETS OF QUARTZ FORMS THE COUNTRY ROCK ADJACENT TO THE QUARTZ VEINS AND SILICEOUS MATERIAL. TINY PYRITE CUBES ARE DISSEMINATED IN THE SILICEOUS MATERIAL. GALENA, SPHALERITE AND CHALCOPYRITE AT THE MINE HAVE BEEN REPORTED.
