The Imperial Mine is a gold and silver mine located in Pershing county, Nevada.
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.
Mine Info
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.

Land Status
Land ownership: BLM Administrative Area
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 (Geology): MINERALIZED AREA CONSISTS OF A NETWORK OF INTERSECTING QUARTZ-PYRITE VEINS COVERING AREA 5 MI. LONG AND 1 1/2 MILES WIDE. THE TOP ZONE IS OXIDIZED, 50-125 FEET IN DEPTH. THE SECONDARY SULFIDE ZONE IS 50-75 FEET IN DEPTH BELOW THE OXIDIZED ZONE, AND CONTAINS SOME CU, PB, ZN WITH HIGH-GRADE AU-AG VALUES. THE PRIMARY SULFIDE ZONE AVERAGES 65 FEET IN DEPTH BELOW THE SECONDARY SULFIDE ZONE.
Comment (Deposit): THE FIRST DISCOVERY IN THE DISTRICT IN 1891, WITH THE GREATEST PERIOD OF DEVELOPMENT AND PRODUCTIVITY BETWEEN 1893 AND 1905. EARLY PRODUCTION WAS OF FREE MINING AU-AG ORE FROM THE SHALLOW OXIDIZED ZONE. DEVELOPMENT WORK TOTALS NEARLY 5 MILES. THE MINES ARE EXTENSIVELY DEVELOPED BY TUNNELS AND DRIFTS THAT CUT AT LEAST 15 VEINS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV
Comment (Location): ON GRANITE MOUNTAIN, EAST FLANK
Comment (Production): RECORDED PRODUCTION FOR THE WHOLE KENNEDY DISTRICT
Comment (Development): MOST PRODUCTION 1893-1905 PERIOD
Comment (Deposit): AT LEAST 15 VEINS. SULFIDES OCCUR IN QUARTZ VEINS CUTTING DIORITE. BIOTITE-BEARIG GRANITE PORPHYRY OCCURS ON THE DUMP, AND SOME SAM-PLES OF VEIN MATTER CONTAIN FRAGMENTS OF A GRANITE PORPHYRY WA-LL (?) MOST OF THE VEINS IN THE DISTRICT WERE REPORTED TO TREN-D NW TO NNW. SOME ROCKS ON THE DUMP ARE SILICIFIED. QUARTZ VEI-NS EXHIBIT SOME OPEN-SPACE TEXTURES. TOURMALINE MAY BE PRESENT- IN QUARTZ VEIN MATTER, AS WELL AS CALCITE.
Comment (Workings): TUNNELS, DRIFTS. ADIT, NUMEROUS PROSPECT PITS, MODERATE SIZED DUMP (SOME MATERIAL WAS REMOVED LATER). ADIT PORTAL IS CAVED(1984)

Nevada Gold
Nevada has a total of 368 distinct gold districts. Of the of those, just 36 are major producers with production and/or reserves of over 1,000,000 ounces, 49 have production and/or reserves of over 100,000 ounces, with the rest having less than 100,000 ounces. Read more: Gold Districts of Nevada.
