Deposit VEIN FAULT IN MAIN ADIT BEARS ALMOST EW, SUNK IN RHYOLITE. SAMPLE 1800 WAS TAKEN FROM VEIN WITHIN LARGE LOWER ADIT ABOUT 50 FT FROM THE ENTRANCE. VEIN VARIES IN WIDTH AND STRIKE, BUT IS CLOSE TO VERTICAL. IT IS VERY PUNKY EXCEPT FOR AREAS OF SILICIFICATION, WITH OTHER AREAS VUGGY AND BRECCIATED.
