    Length 259.08M
    Overall depth 152.4M
    Overall length 103.63M
    Overall width 3.66M

Comments on the workings information

  • THE UNDERGROUND WORKINGS CONSIST OF A DOUBLE-COMPARTMENT 500 FT SHAFT AND A SINGLE-COMPARTMENT 200 FT SHAFT THAT CONTAIN SEVERAL WORKING LEVELS. DRIFTS EXTEND NORTH AND SOUTH ALONG THE VEIN AT THE 100, 200, AND 300 FT LEVELS OF THE 500 FT SHAFT, AND SOUTH ALONG THE VEIN AT THE 30, 70, AND 100 FT LEVELS OF THE 200 FT SHAFT. EACH LEVEL IN THE 200 FT SHAFT CONTAINS STOPES FROM WHICH ORE HAS BEEN REMOVED. THE EXTENT OF MINING IN THE 500 FT SHAFT COULD NOT BE DETERMINED DUE TO CAVING (1973).
