Comments on the geologic information

  • PRINCIPAL MINERAL ASSEMBLAGES: FRBR + SCLT + MLBD + PYRT + QRTZ. MINERALIZED VEINS ARE STRATABOUND TO WOLFRAM SCHIST BELT. MINERALIZATION APPEARS TO REPRESENT EITHER REMOBILIZED (BY METAMORPHIC DIFFERENTIATION) SYNGENETIC CONCENTRATIONS, OR EPIGENETIALLY EMPLACED HYDROTHERMAL SOLUTIONS DERIVED FROM A COOLING GRANITE MAGMA.
  • PRINCIPAL MINERAL ASSEMBLAGES: WLFM + ARPR + SCLT + PYRT + CLCP + BRNT + QRTZ + FLRT. DEPOSIT CONSISTS OF A SINGLE QUARTZ, DIPPING 40 DEGREES TO THE NORTH, VEIN 700 M LONG, 3 TO 40 M THICK AND EXTENDING AT LEAST 200 M DOWN DIP. VEIN IS ASSOCIATED WITH BARREN PEGMATITE.
