Comments on the commodity information

  • VEINS CONTAIN 50-98% QUARTZ, UP TO 25% ADULARIA WITH LESSOR CARBONATE AND HYDROMICAS. ORE MINERALS FORM VERY THIN (0.5-.05MM) SEGREGATIONS OR ZONES OF POWDERY ACCUMULATIONS ALONG THE BOUNDARIES OF COLLOMORPHIC QUARTZ-ADULARIA LAYERS, AND COMPRISE LESS THAN 1-2% OF THE VEIN.

  • Faults And Fractures

Comments on the geologic information

  • CHARACTERISTIC OF THE DEPOSIT ARE WIDESPREAD DEVELOPMENT OF CLAY MINERALS, THE APPEARANCE OF SULPHOSALTS OF ANTIMONY AND TIN IN THE LATE STAGES OF MINERALIZATION, AND THE PRESENCE OF FINELY-BANDED, COLLOMORPHIC STRUCTURES. THE RECOGNIZED PARAGENETIC MINERAL ASSOCIATIONS ARE 1) HYDROMICAS-QUARTZ 2) CARBONATE-QUARTZ 3) A PRODUCTIVE QUARTZ-ADULARIA COMPLEX WITH GOLD-CHALCOPYRITE-PYRITE, AND GOLD-CANFIELDITE-ARGENTITE 4) QUARTZ-HYDROMICAS 5) GYPSUM, KAOLINITE, CARBONATE, AND REDEPOSITED SILVER.

General comments

Subject category Comment text
Deposit THE DEPOSIT LIES WITHIN AN ANCIENT VOLCANIC STRUCTURE WITH SEMICIRCULAR FAULTS AND FRACTURES. THE ORE IS CONFINED TO A BELT OF HYDROTHERMALLY-ALTERED ROCKS, AND A SERIES OF FRACTURES HAS DIVIDED THE DEPOSIT INTO SEPARATE BLOCKS WITH SEVERAL SECTORS OF GOLD MINERALIZATION.
