Deposit LOWER (SW) SHAFT COLLARED IN GREENISH AND PURPLE ANDESITE MUD FLOW. UPPER (NE) SHAFT COLLARED IN THIN-BEDDED RHYOLITE FLOW. A FINE-GRAINED DARK GREENISH-BROWN DIKE FOLLOWS SHEAR ZONE TREND, AND MINERALIZATION MAY OCCUR AT ITS CONTACT WITH FLOW ROCKS. MINOR SILICIFICATION ALONG STRUCTURE. SOME CALCITE VEINING, NO QUARTZ SEEN ALONG ZONE, BUT ROCK IN DUMP HAS PODS AND STRINGERS OF CLEAR QUARTZ WITH DISSEMINATED PYRITE.
