Comments on the production information

  • AVG. TON OF TAILINGS RECOVERED FROM ALL ORE PROCESSED IN MILL CONTAINED GOLD WORTH 70 CENTS. FORMER OPERATORS MINED AND MILLED 10,000 TONS OF ORE FROM THE GLORY HOLE. ESTIMATED TONNAGE OF ORE DEVELOPED FROM THE GLORY HOLE LEVEL IS STATED TO BE 30,000 TONS OF ORE WITH AN AVERAGE VALUE OF $6 PER TON IN GOLD. BETWEEN THE TUNNEL LEVEL AND THE GLORY HOLE LEVEL IT IS ESTIMATED THAT THERE IS DEVELOPED 10,000 TONS OF ORE WITH AN AVERAGE VALUE OF $6 PER TON. BETWEEN THE TUNNEL LEVEL AND THE WINZE LEVEL IT IS STATED THAT THERE IS DEVELOPED 10,000 TONS OF ORE WITH AN AVERAGE VALUE OF $15 PER TON IN GOLD. THE TOTAL ESTIMATED TONNAGE OF ORE IS SAID TO BE 50,000 TONS. IN 1938, PRODUCTION WAS $5000 PER MONTH FOR AN UNSPECIFIED PERIOD.

Comments on the workings information

  • THE MINE WORKINGS CONSIST OF A GLORY HOLE 200 FEET LONG BY 100 FEET WIDE AND THE MAIN WORKING ADIT, CALLED THE "TUNNEL LEVEL" FROM WHICH A WINZE AND "FOOTWALL SHAFT" HAVE BEEN SUNK; LATERAL WORKINGS, INCLUDING THE TUNNEL LEVEL, "INTERMEDIATE LEVEL," AND CROSSCUTS AND DRIFTS RUN FROM THE WINZE AND FOOTWALL SHAFT, ARE MORE THAN 2700 FEET. THE TUNNEL LEVEL EXTENDS 1015 FEET FROM THE PORTAL, AND AN OREBODY 225 FEET LONG, 10 TO 13 FEET WIDE, AND AVERAGING $9.00 PER TON WAS MINED UNDER THE GLORY HOLE. SIXTY FEET ABOVE THE TUNNEL-LEVEL ELEVATION, AN INTERMEDIATE LEVEL WAS DRIVEN; THE LEVEL WAS STOPED AND IS NOW INACCESSIBLE. A WINZE 525 FEET FROM THE PORTAL OF THE TUNNEL LEVEL WAS SUNK 350 FEET, S. 20 DEG W. AT AN AVERAGE INCLINATION OF 65 DEG. DRIFTS WERE RUN IN OREBODY ON THE 100, 200, AND 300-FOOT LEVELS. THE FOOTWALL SHAFT, INCLINED 60 DEG S., LOCATED 542 FEET FROM THE PORTAL OF THE TUNNEL LEVEL, WAS STARTED 45 FEET NORTH OF THE FISSURE AND SUNK TO A DEPTH OF 500 FEET. CROSSCUTS
  • VARYING FROM 45 TO 60 FEET LONG WERE DRIVEN TO INTERSECT THE 100, 200, AND 300-FOOT WINZE LEVELS AND TO CUT THE OREBODY ON THE 400-FOOT LEVEL. DRIFTS ON THE 100, 200, 300, AND 400-FOOT LEVELS WERE 275, 312, 140, AND 200 FEET IN LENGTH RESPECTIVELY; THE LENGTH OF THE OREBODY EXPOSED ON THE FOUR LEVELS WAS 220, 230, 180, AND 220 FEET RESPECTIVELY. THE WIDTH OF THE OREBODY MINED WAS FROM 10 TO 15 FEET. ON THE 500-FOOT LEVEL, AN 80-FOOT CROSSCUT SOUTH OF THE SHAFT FAILED TO CUT THE ORE BUT A TEST HOLE DRILLED FROM THE HEADING SHOWED ORE. THE LEVEL WAS NOT SURVEYED AND IS UNDER WATER. SEVERAL TONS OF BROKEN ORE REMAINS BETWEEN THE 200 AND 400-FOOT LEVELS AS WELL AS A BLOCK OF UNMINED ORE AT THE EAST END OF THE 400-FOOT LEVEL. THE GREATEST POSSIBILITIES FOR ORE THOUGHT TO LIE IN THE EAST PART OF THE MINE BELOW THE TUNNEL LEVEL. SKETCH MAP OF WORKINGS IN NORMAN AND STEWART (1951).
