Comments on the geologic information

  • ALONG SE DRILL ROADS, MOST CONSPICUOUS FEATURE IS VININI-HOSTED JASPEROID BRECCIA FORMING A RESISTANT NW-STRIKING RIB ABOVE DRILL ROADS. JASPEROID IS HIGHLY SILICIFIED, FRACTURED, AND FE-STAINED ALONG THE FRACTURES. BEDDING IS PRESERVED IN THE JASPEROID IN PLACES AND DIPS SE. BELOW THE JASPEROID BRECCIA ARE THIN CONTORTED BEDS OF BLACK CARBONACEOUS SHALES. IN ONE AREA THE SE-DIPPING SHALES ARE CUT BY AN ALTERED IGNEOUS DIKE, MOSTLY ALTERED TO CLAYS. THE SURROUNDING SHALES HAVE BEEN BLEACHED. NBMG SAMPLE 1517 A WAS TAKEN HERE, OF BLACK SILICEOUS SHALE AND CHERTY SHALE DRILL CUTTINGS. TO THE NW IN PROBABLE PROPOSED PIT AREA (1982) THE RESISTANT RIB OF VININI JASPEROID BRECCIA IS STILL PRESENT. BELOW THE BRECCIA ARE THIN BEDDED SILICEOUS SEDIMENTS. A LARGE BOULDER OF BRECCIA FOUND ON THE ROAD WAS CUT BY A SMALL BRECCIA VEIN CONTAINING A CLAST OF QUARTZ-EYE PORPHYRY. HOWEVER, THE MOST NOTABLE OCCURRENCE WAS OF ABUNDANT EUHEDRAL JAROSITE CRYSTALS DEVELOPED IN THE OPEN FRACTURES OF THE
  • JASPEROID (SAMPLE 1518B). SOME BARITE VEIN AND GANGUE WAS ALSO NOTED IN THIS AREA. NBMG SAMPLE 1519 CONSISTS OF DRILL CUTTINGS OF DARK GREY CALCAREOUS SHALES WITH FINE DISSEMINATED SULFIDES.
