Deposit DOUBLE-PORTALLED ADIT BEGINS IN MASSIVE SILICEOUS OUTCROP OF QUARTZ-VEINED VOLCANIC AND QUARTZ-CEMENTED VOLCANIC BRECCIA. RUBBLY OUTCROPS OF QUARTZ-CEMENTED BRECCIA CONTINUE FOR AT LEAST 100 FT ABOVE LOWER ADIT (SAMPLE LOCATION 1709). OUTCROPS CONSIST OF AN INTERLOCKING NETWORK OF COCKSCOMB PRISMATIC, BANDED AND OPEN-CENTERED SUGARY WHITE QUARTZ VEINS AND VEINLETS WHICH CEMENT LIGHT PURPLE ANDESITE-DACITE(?) VOLCANIC BRECCIA FRAGMENTS. THE FRAGMENT ARE INTENSELY SILICIFIED AND HYDROTHERMALLY ALTERED. THE FRAGMENTS ARE LIGHT PURPLE IN COLOR WITH AN APHANITIC GROUNDMASS WHICH CONTAINS CLAY AND IRON-ALTERED PHENOCRYSTS OF PLAGIOCLASE AND CHLORITIZED HORNBLENDE(?) CRYSTALS. QUARTZ COMPRISES MORE THAN 50% OF THE BRECCIA ZONE WITH VEINS AS WIDE AS 1 IN AND AVERAGING 0.5 IN. IN WIDTH. QUARTZ AFTER CALCITE IS VERY COMMON. OXIDIZED PYRITE OCCURS IN THE FRAGMENTS AND IN THE VEIN MATERIAL. SOME FRAGMENTS ARE CUT BY EARLY-STAGE VITREOUS QUARTZ VEINLETS SOME OF THE VEIN MATERIAL IS LIGHT GREEN AND
Deposit PINK AND MAY CONTAIN FLUORIDE AND/OR ADULARIA. THE N-S-TRENDING ADIT FOLLOWS A VERTICAL SHEAR ZONE ABOUT 3 FT WIDE. THE E-W ADIT FOLLOWS A LESS PRONOUNCED SHEAR ZONE. ENTIRE OUTCROP AT PORTAL IS SI
