Comments on the workings information

  • THE MINE CONTAINS OVER 2000 FT OF UNDERGROUND WORKINGS IN THE FORM OF SHAFTS, DRIFTS, AND CROSSCUTS. THE MAIN SHAFT, WHICH IS ON A MINUS 37 DEGREE INCLINE AND HEADS S85W, HAS WORKING LEVELS AT 100, 200, AND 300 FT. ON THE 100 FT LEVEL, THE VEIN HAS BEEN DRIFTED UPON FOR 110 FT NORTH AND 60 FT SOUTH. THIS LEVEL REACHES THE SURFACE 110 FT NORTH AND 67 FT SOUTH OF THE SHAFT COLLAR. ON THE 200 FT LEVEL, A DRIFT FOLLOWS THE VEIN 75 FT NORTH AND 205 FT SOUTH. THE 300 FT LEVEL WORKINGS ARE UNKNOWN. ABOUT 110 FT SE OF, AND 15 FT LOWER THAN THE COLLAR OF THE SHAFT, AN ADIT HAS BEEN DRIVEN SW 170 FT. NEAR THE FACE OF THIS ADIT, A SPARSELY MINERALIZED VEIN, HAS BEEN DRIFTED UPON 35 FT SOUTH AND 105 FT NORTH.

Comments on development

  • DEVELOPMENT FROM 1886-1890, 1969-1970 (FLOTATION MILL CONSTRUCTED, BUT NOT COMPLETED DURING THIS TIME), 1971, 1972, 1977, AND 1979; LIMITED EXPLORATION IN 1979.

General comments

Subject category Comment text
Deposit QUARTZ FISSURE VEINS, WITH BANDED QUARTZ. THE ORE MINERALS FOR THE MOST PART ARE ONLY SPARSELY SCATTERED THROUGHOUT THE VEIN. IN SOME PARTS OF THE VEIN, THE ORE MINERALS ARE CONCENTRATED INTO BANDS UP TO SEVERAL FEET WIDE THAT PARALLEL THE WALLS OF THE VEIN.
Deposit COMPRISED OF JUMBO, GOLDEN CROWN, LONE STAR, GUBSER, AND MINERAL HILL PROPERTIES
