Comments
Comment (Commodity): ORE FROM LOWER LEVELS WAS HIGHER GRADE BUT IS DIFFICULT TO TREAT BECAUSE OF THE SULFIDES.
Comment (Production): SEVERAL THOUSAND TONS OF OXIDIZED SURFACE ORE WAS MINED AND MILLED ABOUT 1900. NEARLY 100,000 POUNDS OF WHITE ARSENIC WAS RECOVERED FROM CONCENTRATES SHIPPED TO THE GLOBE SMELTER.
Comment (Deposit): THREE SHOOTS RANGING IN WIDTH FROM 10 TO 30 FEET. A SMALLER VEIN LIES EAST OF THE MAIN VEIN, 8 TO 10 FT WIDE.
Comment (Workings): DEVELOPMENT IS BY CROSSCUTS FROM THE SURFACE AND BY DRIFTS AND CROSSCUTS FROM A SHAFT AT THE NEARBY COLUMBIA MINE. A SMALLER VEIN LYING TO THE EAST OF THE MAIN VEIN IS 8 TO 10 FEET WIDE AND HAS BEEN DEVELOPED THROUGH A LENGTH OF 100 FEET
Comment (Reserve-Resource): CONTAINING $12.75 A TON IN GOLD.
Comment (Geology): THREE SHOOTS RANGING IN WIDTH FROM 10 TO 30 FEET. A SMALLER VEIN LIES EAST OF THE MAIN VEIN, 8 TO 10 FT WIDE
