Deposit MINE LOCATED NORTH OF LAKE CITY CALDERA WALL IN UNCOMPAHGRE CALDERA MOAT-FILL SEQUENCE OF EUREKA MEMBER RHYOLITE, AND IN TRANSVERSE FAULT IN SLACK'S (1980) BARITE/PRECIOUS METALS ASSEMBLAGE, INNER QUARTZ-SPHALERITE ZONE. IRVING AND BANCROFT (1911) DESCRIBE ORE AS DEVELOPED ALONG SERIES OF INTERSECTING FRACTURES TRENDING N 10 E AND N 35 W. MINERALIZATION ALTERNATES BETWEEN TWO TRENDS AS FRACTURES ALONG ONE TREND NARROW. VEIN IS SHEETED ZONE IN PLACES, BUT DUE TO BRECCIATION, IT CONTAINS ANGULAR INCLUSIONS OF COUNTRY ROCK, BRANCHES, AND OTHER IRREGULARITIES. VERY FINE DRUSES PARALLEL VEIN WALLS AND FOLLOW PERIPHERY OF INCLUSIONS. SECONDARY PYRARGYRITE FILLS CRIVICES IN EARLIER ORE AND OCCURS AS CRYSTALS ON QUARTZ DRUSES IN OPEN CAVITIES. PROBABLE SECONDARY GALENA COATS SURFACES OF SPHALERITE ALONG CRACKS AND FRACTURES.
