Comments on the geologic information

  • THE MINE WAS OPENED IN A ZONE OF SHEARED ARGILLITE AND PHYLLITE EXTENDING SOUTHEAST FROM THE LEWIS, PHIFER AND ORE HILL MINES. MUCH MILKY, IRON-STAINED VEIN QUARTZ IS NEAR THE WORKINGS. IN PLACES THE QUARTZ IS ASSOCIATED WITH SILICEOUS COUNTRY ROCK, AND TINY CRYSTALS OF PYRITE ARE DISSEMINATED THROUGH THE ZONE. A SMALL AMOUNT OF DARK, REDDISH BROWN SPHALERITE IS ALSO IN THE SILICEOUS ROCK.
