The Silica Mine is a silica mine located in Pershing county, Nevada at an elevation of 4,600 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.
Elevation: 4,600 Feet (1,402 Meters)

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.

Primary: Silica Mine
Secondary: My Pal Group
Secondary: NBMG Sample Site 2545
District: Table Mountain District
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.

Analytical Data: SAMPLE 2545 CONTAINS 2 % FE, 0.02 % MG, 1 % CA, 0.2 % TI, 10 PPM AG, 50 PPM B, 700 PPM BA, 20 PPM CR, 50 PPM CU, 5 PPM NI, 30 PPM V, 200 PPM ZR, AND +5.0 PPM HG. THE SAMPLE WAS CHIPPED FROM PIT OF SHALES AND ACID-LEACHED ROCK.
Comment (Location): SE COR. SEC. 2
Comment (Development): "AS THE MAJOR EMPHASIS HERE SEEMS TO HAVE BEEN ON DEVELOPING THE DEPOSIT FOR ITS SILICA POTENTIAL, PERHAPS THE SEARCH FOR MINEABLE MERCURY HAS BEEN NEGLECTED."
Comment (Deposit): POSSIBLY HOT-SPRINGS DEPOSIT. NE-TRENDING ACID-LEACHED ZONE IN MESOZOIC SHALES APPEARS TO PARALLEL RANGE-FRONT. SOME FRAGMENTS OF ACID-LEACHED GRANITE SEEN ON DUMP, BUT NOT IN PLACE. ACID-LEACHED ROCK APPEAR TO CONSIST OF CRISTOBALITE? AND OPAL GRADING INTO SERICITE AND CLAYS, SOME FE OXIDE LOCALLY AND IN THE WHITE TUFF ARE VERTICAL ZONES OF SILICIFICATION, ALTERATION, AND FE-MN STAIN. PANNING OF A FEW SAMPLES GRABBED FROM VARIOUS POINTS IN THE WALLS OF THE MAIN SILICA PITS, INCLUDING THE MAIN ALTERED ZONES FAILED TO YIELD ANY CINNABAR. HOWEVER A SAMPLE TAKEN IN ONE OF THE SMALLER NORTHERN CUTS EXCAVATED IN REDDISH, SHALY PHYLLITE YIELDED MORE THAN 50 GRAINS OF CINNABAR ON PANNING.

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 at Gold Districts of Nevada.
