The Mina Development Co. Mine is a mercury mine located in Mineral county, Nevada at an elevation of 7,402 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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Deposit): PROPERTY INCLUDES A PART OF THE LOST STEERS GROUP, THE ORIGINAL MERCURY DISCOVERY IN THE DISTRICT. ; INFO.SRC : 1 PUB LIT
Comment (Development): THE MINE WAS WORKED INTERMITTENTLY FROM 1920 TO 1940 (1800 FLASKS PRODUCED); A HIGH-GRADE ORE BODY WAS DEVELOPED IN 1940-41(1200 FLASKS PRODUCED)
Comment (Deposit): CINNABAR REPLACES LIMESTONE AND OCCURS AS HIGH-GRADE PODS IN BROKEN LIMESTONE, AS CRYSTALS IN CALCITE STRINGERS CUTTING LIMESTONE, AS FILMS ON THE SLICKEN SIDEDSURFACE OF FAULT PLANES, AND AS DISSEMINATED CRYSTALS IN FAULT GOUGE. THE ORE BODIES ARE LOCALIZED ALONG THE SW-TRENDING NORMAL FAULTS THAT PREDATE MINERALIZATION AND HEADING SLIPS ADJACENT TO THESE FAULTS. THREE CLOSELY ASSOCIATED TYPES OFORE BODIES ARE EXPLOTED. IN THE FIRST CINNABAR PARTLY FILLED CRACKS AND PARTLY REPLACED THE LIMESTONE; THIS TYPE WAS EXCEPTIONALLY RICH AND YIELDED MOST OF THE QUICKSILVER. IN THE SECOND TYPE, WHICH WAS LOWER IN GRADE, CINNABAR ONLY FILLED CRACKS IN THE LIMESTONE. IN THE THIRD TYPE, CINNABAR WAS CONCENTRATED IN GOUGE ALONG THE NORMAL FAULTS.
Comment (Workings): THE WORKINGS CONSIST OF ABOUT 5000 FT OF DRIFTS AND CROSSCUTS ON 7 LEVELS; THE LOWER 2 LEVELS ARE FLOODED.
Comment (Geology): COUNTRY ROCK IS LIMESTONE WITH INTERBEDDED THIN LAYERS OF CONGLOMERATE, SANDSTONE, AND SHALE,
Comment (Location): AT THE HEAD OF CINNABAR CANYON ; INFO FROM LAND.ST :(1972)
