Deposit CONTAINING SOME EUHE DRAL BARITE CRYSTALS, GREEN AND YELLOW OXIDES (PB? AS? SB?), COATINGS AND PODS OF MANGANESE AND MINOR CU OXIDES. SOME MINOR GALENA (VERY FINE-GRAINED) AND OTHER UNOXIDIZED FINE-GRAINED METALLICS ALSO NOTED. THE VEIN-ROCK IS GENERALLY BRECCIATED. SAMPLE SITE 1733 IS A SHAFT INCLINED TO THE WEST ALONG BEDDING PLANE IN BLEACHED, TAN, SILTY CARBONATE ROCKS. THE LIMESTONE IS LOCALLY RECRYSTALLIZED, SILICIFIED AND IRON-STAINED. AN OXIDIZED REPLACEMENT DEPOSIT WHICH CONFORMS WITH THE BEDDING OF THE HOST ROCK IS EXPOSED IN THE SHAFT. THE REPLACED ZONE AND BEDDING STRIKE N20E, DIP 40 NW. THE REPLACED HORIZON IS 1-2 FT WIDE AT ITS NORTHERN EXPOSURE IN SHAFT AND PINCHES OUT TO SEVERAL LENSES A COUPLE OF INCHES WIDE TOWARD THE SOUTH. THE ZONE APPEARS TO COINCIDE WITH A MORE SANDY, POROUS HORIZON IN THE LIMESTONE UNIT. IT IS CHARACTERIZED BY HEAVY IRON-STAINING AND IN ITS CENTRAL PORTION CONTAINS COARSE BLADED CRYSTALS OF BARITE CEMENTED BY A POROUS GOSSANY MIXTURE OF SILICA
Deposit CALCITE AND IRON OXIDES. GOSSANY AND POROUS CALCITE/BARITE/SILICA VEIN MATERIAL ON THE DUMP CONTAINS VERY FINELY CRYSTALINE GALENA AND FLUORITE(?) AND ALSO POSSIBLY SOME TETRAMEDRITE. AZURITE AND MAL
