Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Location): ON NE SIDE OF SOUTH MTN 180 FT NNE OF ESMOND MINE. PORTAL ELEV FROM STEVEN AND RATTE (1960, PL. 4). ; INFO FROM LAND.ST :1975
Comment (Deposit): MINE DEVELOPED AT NW END OF 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 EXMOND VEIN. MASS CONTAINS IRREGULARLY DISTRIBUTED COMPACT QUARTZ ZONES WITH VUGGY QUARTZ PIPELIKE ORE 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 ELONGATE BRANCHING BODIES REFLECTING FORMER JOINT PATTERN TO 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.
Comment (Workings): TUNNEL DRIVEN GENERALLY N 70 W FOR 95 FT WITH SEVERAL BRANCHING DRIFTS TOTALLING APPROX 420 FT.
