Comments on the geologic information

  • FOUR QUARTZ VEINS CROP OUT DISCONTINUOUSLY FOR 1400 FEET. LARGEST IS 1-15 FEET THICK IN THE QUARTZITE, AVERAGES 6 FEET WHERE MINED. ORE SHOOTS GENERALLY IN WIDER PART OF THE VEIN, AND LOCALIZED BY SMALL CHANGES IN ATTITUDE OF THE VEIN WHERE MOVEMENT HAS BRECCIATED THE QUARTZ . A PARALLEL FISSURE SEVERAL HUNDRED FEET NORTH OF THE COMET VEIN CONTAINS UP TO 1.4% W03 BUT WAS UNDEVELOPED AS OF 1970. WASTE ROCK ON DUMPS IS PINK, WELL-SORTED, FINE-TO MEDIUM-GRAINED LAMINATED AND/OR MICACEOUS QUARTZITE WITH MINOR REDDISH SILICIFIED SILTSTONE AND SHALE. SOME OXIDIZED PYRITE IS DISSEMINATED THROUGHOUT THE ROCKS. MINERALIZED ROCK ON DUMPS CONSISTS OF MASSIVE SUGARY WHITE TO VITREOUS GREY QUARTZ VEIN MATERIAL. VEIN CONSISTS OF A SET OF PARALLEL VEINS, GIVING IT A BANDED, FISSURED APPEARANCE. SOME LATE-STAGE VUGGY AND/OR OPEN-CENTERED VEINS AND VEINLETS CUT MORE MASSIVE VITREOUS VEINS. THE VEINS, ESPECIALLY THE IRON-STAINED VUGGY VARIETY, CONTAIN FINE TO COARSE CLOTS AND STRINGERS OF PYRITE,
  • CHALCOPYRITE, GALENA, SPHALERITE, COPPER OXIDES, IN ADDITION TO LESSER BORNITE, CHRYSOCOLLA AND MALACHITE. DARK GREENISH-BROWN CLOTS AND COARSE TABULAR CRYSTALS OF HUEBNERITE-FERBERITE (?) (OR POSSIBLY

Comments on the workings information

  • MINE OPENED BY 3 SHAFTS; MOST OF THE WORK DONE FROM THE MAIN SHAFT BETWEEN THE 168 LEVEL AND THE SURFACE. IN 1983, MAIN SHAFT (VERTICAL) HAD HEAD FRAME AND HOIST HOUSE, TRACKS, LARGE DUMPS, MILLSITE DOWNSLOPE FROM SHAFT. ALSO, EXTENSIVE AREA OF BULLDOZER WORK AND DRILLROADS (?) ON W FLANK OF HIGHLAND RANGE E AND NE OF COMET MINE. . IN 1983, MAIN SHAFT (VERTICAL) HAD HEAD FRAME AND HOIST HOUSE, TRACKS, LARGE DUMPS, MILLSITE DOWNSLOPE FROM SHAFT. ALSO, EXTENSIVE AREA OF BULLDOZER WORK AND DRILLROADS (?) ON W FLANK OF HIGHLAND RANGE E AND NE OF COMET MINE.

Comments on development

  • NO ACTIVITY AT TIME OF EXAMINATION IN 1983, BUT RECENT ROADWORK AT MINESITE INDICATES RENEWED AND CONTINUING INTEREST IN THE PROPERTY. COMET COALITION MINES INCLUDED THE FORLORN HOPE, LOG CABIN, COMET, AND PAN AMERICAN AND SCHODDE MINE PROPERTIES IN 1949.
