  • E SIDE OF MAJOR ALTERATION SILICIFICATION OF DISTRICT. SHEAR ZONE APPEARS TO TREND SW THRU CURTZ & GEORGIANA MINES, & THEN SE ALONG S SIDE OF MONITOR CANYON NEAR ZACA MILL. MINE DUMP HAS WHITE SILICFIED ROCK THAT CONTAINS MOSTLY FINE - TO - MEDIUM GRAINED MINERALS. SILICFIED HILL TOP STANDS OUT FROM SURROUNDING UNALTERED ANDESITE. IN PLACES THE SILICFIED ROCK IS IRON OXIDE STAINED.
