Comments on the geologic information

  • PERSISENT SHEAR ZONE FORMS SCHISTOSE MYLONITE ZONES IN FOLIATED TO GNEISSIC GRANITOID ROCKSuAND CONTROLS MINERALIZED QUARTZ-CARBONATE VEINS. VEINS RANGE 0.3 TO 2.5 M THICKuAND PERSIST FOR ABOUT 5 KM. IMMEDIATE WALLROCKS ARE SHEARED ON ONE OR BOTH WALLS FOR 0.5 M. ORE SHOOTS UP TO 60 M IN LENGTH PITCH AT 45uTOWARD THE SOUTHEAST IN THE PLANE OF THE VEIN. GOLD WAS PRODUCED FROMuGOSSAN (BROWN ORE) TO A DEPTH OF AOUBT 15 M. COPPER WAS USUALLY PRODUCED FROM 15 TOu30 M. THE VEIN WAS 0.6 M AT SURFACE INCREASING TO 7.5 M AT THE 130 FT.uLEVEL THEN DECREASING TO 1-2 M AT THE 350 FT. LEVEL.

Workings at the site

  • Type of workings Underground
    Length 600M
    Overall depth 107M
    Overall length 4800M

Comments on the workings information

  • SHAFTS WERE SUNK ON THE PROPERTY TO 200 FT. (RODMAN), 240 FT., AND 350 FT. (EUDY). THERE WERE SEVERAL THOUSAND FT. OF UNDERGROUND WORKINGS. THE EUDY SHAFT HAD LEVELS DEVELOPED AT 90, 130, AND 150 FT. AND WAS CONNECTED TO THE JACKS HILL AND LINDSAY DEPOSITS AT THE 130 FT. LEVEL. IN 1966 THERE WERE THREE FILLED SHAFTS.

Comments on development

  • LITTLE WORK HAS BEEN DONE SINCE 1860, EXCEPT IN 1883 WHEN THE OLD MINE DUMPS WERE WORKED. THIS WORK WAS ABANDONED IN 1885.
