Deposit TWO VEINS, 18 INCHES TO 2 FEET THICK, ARE FILLED WITH CRUSHED ANDESITE AND QUARTZ. RICH SILVER ORE (AS MUCH AS 100 OZ/TON) OCCURS IN BUNCHES IN VEINS. AG-PB ORE ALSO OCCURS IN STOCK-WORK LENSES IN THE ANDESITE OUTSIDE THE VEIN, ALSO SOME DISSEMINATED PYRITE AND CHALCOPYRITE IN THE WALL ROCK.
