Comments
Comment (Location): LOCATION IS OF NO. 1 SHAFT
Comment (Workings): THE LENGTH OF WORKINGS INCLUDES ADJACENT MINES. THE MINE IS DEVELOPED BY TWO SURFACE SHAFTS, FOUR UNDERGROUND WINZES WITH DRIFTS AND CROSSCUTS. NO. 1 SHAFT IS 1,850 FEET DEEP WITH NINE LEVELS. NO. 2 SHAFT IS 1,800 FEET DEEP; IT IS USE FOR VENTILATION AND ESCAPE. THE LOWEST LEVEL IS AT 3,050 FEET BELOW THE SURFACE.
Comment (Geology): GEOL.DESC: 2 ORE ZONES
Comment (Development): 1980-UNDER EXPLORATION BY ASARCO
Comment (Deposit): GRANITE CLAIMS PIPE(75 FEET IN DIAMETER AND 800 FEET THICK); THIS IS ONE EXAMPLE OF THE MANY ORE BODIES IN THE MINE.
Comment (Production): $48,770,940 (NET FROM THE SMELTER AT PREVAILING PRICES)
