The Calico Hills Area is a iron and magnesite mine located in Nye county, Nevada at an elevation of 4,501 feet.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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.

Comment (Deposit): POSSIBILITY OF BURIED INTRUSIVE UNDERLYING SILICATED ROCKS. ; INFO.SRC : 3 FIELD OBSERV; 1 PUB LIT; 2 UNPUB REPT
Comment (Location): RESTRICTED ACCESS; ON NEVADA TEST SITE. ABOUT 6 MILES N OF THE CANE SPRINGS RD ON THE NEVADA TEST SITE ; INFO FROM LAND.ST :1982
Comment (Development): INACTIVE AT TIME OF EXAMINATION. USGS HAS DONE EXTENSIVE GEOPHYSICAL WORK IN AREA, DRILLED ONE DEEP DIAMOND DRILL HOLE ON WEST SIDE OF ALTERED AREA. EXAMINED AS POSSIBLE NUCLEAR WASTE DISPOSAL SITE
Comment (Deposit): VEINLETS ALONG THRUST FAULT. ARGILLITE IS SILICATED, FRACTURED, WITH VEINLETS OF SILICATE MINERALS
Comment (Workings): SEVERAL SMALL PROSPECT TRENCHES; 3 SHALLOW SHAFTS; 10 PROSPECTS, ONE 2500-FT DRILL HOLE
Comment (Geology): ARGILLITE OF ELEANA FM IS SILICATED, FRACTURED WITH VEINLETS OF SILICATE MINERALS, SOME EPIDOTE GARNET, MAGNETITE, FORMS LOWER PLATE OF THRUST. UPPER PLATE BLEACHED SILICATED NEVADA FM WITH BRUCITE PROSPECTS IN NEVADA DOLOMITE AT THRUST CONTACT. SILICATED ROCKS FORM BASIN AND LOWER RIDGES; CALICO HILLS TUFFS CAP RIDGES. TUFFS ARE BLEACHED AND ALTERED WITH LOTS OF VIVID HEMATITE COLORATION AND SOME JASPEROID VEINING. SMALL RHYOLITE PLUGS FORM SMALL HILLS IN THE BASIN, ARE BRECCIATED AND CONTAIN ARGILLITE FRAGMENTS. WITHIN VEINS ARE PODS OF COPPER MINERALS
