| Deposit | ONE ADIT WAS SELECTED FOR SAMPLING IN 1986, BECAUSE OF ITS ACCESS. IT WAS IN HIGHLY BLEACHED AND ARGILLIZED RHYOLI-TE WITH SILICIFIED ZONES WITHIN IT. ADIT WAS DRIVEN ON A SHEAR- ZONE (SAMPLE 3151) ALONG LIMONITE-STAINED SILICIFIED PORTIONS- OF THE VEIN, ALTHOUGH THERE WAS NO VISIBLE MINERALIZATION (RE-PORTEDLY FREE GOLD). MOST VEINING OCCURS AS STRINGERS-THIS ONE- ABOUT 2 FT WIDE, BEARING N45E, 55 NW; IT APPEARS TO BE TYPICA-L OF THOSE EXAMINED. ANOTHER VEIN ALONG A SHEAR ZONE IS EXPOSE-D IN A SHAFT SOUTH OF THE CAMP AND WAS ALSO SAMPLED (3152). TH-IS VEIN BEARS N55E, DIP NW, 2 FT WIDE IN ALTERED AND BLEACHED -WHITE TUFF? STRINGER OF FE-OXIDE-STAINED QUARTZ UP TO 8 INCHES- THICK. |
