Comments
Comment (Location): UNSURVEYED TOWNSHIP AND RANGE.
Comment (Deposit): OF GALENA, SPHALERITE, SPECULARITE, OXIDIZED PYRITE, AND ABUNDANT FE AND MN OXIDES WITHIN A MANGANOSIDERITE-CALCITE-QUARTZ GANGUE. ROCKS ARE HEAVY AND SILICIFIED, AND EUHEDRAL CRYSTALLINE QUARTZ LI
Comment (Workings): SERIES OF SHORT ADITS, PROSPECTS AND SHAFTS ALONG VEIN STRUCTURE. LOWER ADIT IS 10-12 FT DEEP, TRENDS S70E. LARGEST WORKING IS ABOVE SAMPLED ADIT, TRENDS SE, INCLINED SHAFT ABOUT 30 FT DEEP. BULLDOZING, TRENCHING DONE RECENTLY. OLD CABIN OF HAND-HEWN LIMESTONE BLOCKS BELOW WORKINGS
Comment (Development): RECENT (WITHIN YEAR PRIOR TO AUG 1983) SCRAPING AND TRENCHING WITH BULLDOZER. ROAD TO CABIN IS EXTENSIVELY BULLDOZED. DOZING MAY BE IN PREPARATION FOR DRILLING; UPPER ROADS NOT VISITED; POSSIBLY DRILL SITES.
Comment (Deposit): SHORT ADIT FOLLOWS AN OXIDIZED SULFIDE REPLACEMENT VEIN IN THICK-BEDDED (1-FT BEDS) TO MASSIVE LIMESTONE BEDS. UPPER ADIT IS IN BOLD CARBONATE, OUTCROP. AT LOWER ADIT, THE HOST LIMESTONE IS A MEDIUM GREY SUGARY SLIGHTLY DOLOMITIC (SILICIFIED?) LIMESTONE CONTAINING ALGAL STRUCTURES AND FOSSIL FRAGMENTS. NEAR VEIN, FOSSIL REMNANTS ARE REPLACED BY CALCITE OR IRON OXIDES. VEIN IS WELL-EXPOSED AT LOWER AND UPPER PORTALS. THE "VEIN" OR ALTERED FRACTURE (FISSURE) ZONE IS ABOUT 3-5 FT WIDE, STRIKING N 70 W AT LOWER WORKING TO E-W AT UPPER WORKING. ALTERED LIMESTONE WITHIN ZONE IS SILICIFIED AND CONTAINS ABUNDANT FE AND MN OXIDES. REPLACEMENT APPEARS TO HAVE TAKEN PLACE ALONG SEVERAL VERTICAL FRACTURES OR FISSURES AT A HIGH ANGLE TO THE BEDDING. THE ALTERED ROCK WITHIN THE ZONE SHOWS GOSSANY HONEYCOMB BOXWORKS AND IRREGULAR PODS AND VEINS OF COARSE CALCITE/SIDERITE, QUARTZ AND MANGANOSIDERITE. SAMPLE 1441 WAS COLLECTED FROM OUTCROP AT PORTAL AND CONSISTS OF REPLACEMENT ORE WITH IRREGULAR CLOTS
