Subject category Comment text
Deposit MINES DEVELOPED IN COPPER HILL-ESMOND VEIN ZONE, A LARGE MASS OF HIGHLY SILICIFIED ROCK IN QUARTZ-ALUNITE ZONE EXTENDING ACROSS MAIN MINERALIZED AREA FROM COPPER HILL KNOB TO ESMOND VEIN. MASS CONTAINS IRREGULARLY DISTRIBUTED COMPACT QUARTZ ZONES WITH VUGGY QUARTZ PIPELIKE BODIES. LARGE SILICIFIED MASS CAPPING COPPER HILL KNOB APPARENTLY GIVES WAY AT DEPTH TO SERIES OF MORE DISTINCT SILICIFIED ZONES SEPARATED BY SEPTA OF LESS ALTERED ROCK. ON SURFACE, VUGGY QUARTZ MASSES RANGE FROM ELONGGATE BRANCHING BODIES REFLECTING FORMER JOINT PATTERN RO MORE PIPELIKE MASSES WITH IRREGULAR BUT GENERALLY EQUIDIMENSIONAL HORIZONTAL CROSS-SECTIONS. LARGEST MASSES OF VUGGY QUARTZ ROCK OCCUR NEAR NW END OF VEIN ZONE NEAR ESMOND AND DEL NORTE MINES AND PICKENS CUT. HIGHLAND MARY MINE DEVELOPED IN LARGE ELONGATE SILICIFIED MASS IN CENTER OF VEIN ZONE.
