Subject category Comment text
Deposit POSSIBLY HOT-SPRINGS DEPOSIT. NE-TRENDING ACID-LEACHED ZONE IN MESOZOIC SHALES APPEARS TO PARALLEL RANGE-FRONT. SOME FRAGMENTS OF ACID-LEACHED GRANITE SEEN ON DUMP, BUT NOT IN PLACE. ACID-LEACHED ROCK APPEAR TO CONSIST OF CRISTOBALITE? AND OPAL GRADING INTO SERICITE AND CLAYS, SOME FE OXIDE LOCALLY AND IN THE WHITE TUFF ARE VERTICAL ZONES OF SILICIFICATION, ALTERATION, AND FE-MN STAIN. PANNING OF A FEW SAMPLES GRABBED FROM VARIOUS POINTS IN THE WALLS OF THE MAIN SILICA PITS, INCLUDING THE MAIN ALTERED ZONES FAILED TO YIELD ANY CINNABAR. HOWEVER A SAMPLE TAKEN IN ONE OF THE SMALLER NORTHERN CUTS EXCAVATED IN REDDISH, SHALY PHYLLITE YIELDED MORE THAN 50 GRAINS OF CINNABAR ON PANNING.
