Comments on the geologic information

  • VEIN VARIES IN THICKNESS FROM 6 TO 25 INCHES, AVERAGING 12 INCHES. STIBNITE OCCURS AS PODS, VEINLETS, AND FINE HAIRLIKE CRYSTALS, COMMONLY IN QUARTZ AND CALCITE STRINGERS. PYRITE PRESENT ALONG EDGE OF QUARTZ STRGERS. STIBNITE ALSO OCCURS ALONG BEDDING PLANES IN THE CONTORTED AND BRECCIATED ALE WALL ROCK. THE STIBNITE HAS BEEN PARTIALLY OXIDIZED TO YELLOW AND WHITE SB-ODES NEAR THE SURFACE.

Comments on the workings information

  • DEPOSIT IS DEVELOPED BY A 264-FT INCLINED SHAFT FROM WHICH SOME 440 FEET OF DRIFTING AND CONSIDERABLE STOPING WERE DONE.

Comments on development

  • CONSISTS OF TWO ORE BODIES MINED AT DIFFERENT TIMES. THE SOUTHERN BODY WAS FIRST MINED IN 1916; THE NORTHERN IN 1946. THE DEPOSIT WAS EXPLORED BY TRENCHING FOR 2500 FT ALONG SHEAR ZONE. NO ACTIVITY IN 1985.
