Comments on the geologic information

  • PRINCIPAL MINERAL ASSEMBLAGES: WLFM + QRTZ + FLRP + BOTT + PYRT + CLCP + TOPZ. LODE DEPOSIT CONSISTS OF QUARTZ VEIN CUTTING BOTH PHYLITE AND GRANITE; STOCKWORK DEPOSITS OCCUR IN BRECCIATED PHYLLITE ALONG CONTACT GRANITE. VEINS ARE NARROW AND WOLFRAMITE IS VERY FINE-GRAINED. PLACER (ELUVIAL) DEPOSITS OCCUR IN GRAVELS BELOW BEDROCK DEPOSITS.
