Deposit DUMP ROCKS SHOW FINE SILICEOUS VEINING AND MINUTE CLOTS OF PARTIALLY OXIDIZED PYRITE. ABOVE AND NE OF ADIT, MICACEOUS BROWN SHALES OUTCROP ALONG SLOPE BELOW A SANDY LIMEY HORIZON WHICH IS ALTERED TO A LIGHT GREEN DENSE BANDED CALC-SILICATE WHICH IS FINE-GRAINED AND CONTAINS ABUNDANT EPIDOTE AND CALCITE. THE CALC-SILICATE HORIZON EXTENDS TO DRILL ROAD LOCATED ABOUT 30 FT ABOVE ADIT. THE ROCKS ON THE DRILL ROAD ARE MICACEOUS BROWN AND GREEN SHALES. SOME OF THE SHALES ARE LIMEY AND ALSO SHOW SILICATION EFFECTS: MICA IN THE SHALES IS RECRYSTALLIZED IN RESPONSE TO THERMAL(?) METAMORPHISM. THE SHALES AND LIMEY MUDSTONES FORM 1-6 INCH BEDS WHICH STRIKE N65E AND DIP 30 SE. HOWEVER, ATTITUDES ON BEDDING CHANGE DUE TO SMALL NNW-STRIKING FAULTS OBSERVED IN ROAD CUT AND A LARGER E-W FAULT MAPPED IN AREA BY CALLAGHAN (1937). A LARGE RHYOLITE DIKE IS LOCATED ABOUT 0.25 MILE WEST OF SAMPLED OUTCROP. A FEW MINUTE FLAKES OF SCHEELITE WERE OBSERVED WHEN CALC-SILICATE SAMPLE WAS LAMPED.
