The Schwartz Tunnel is a tungsten, copper, silver, and zinc mine located in Lincoln county, Nevada at an elevation of 9,301 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: 9,301 Feet (2,835 Meters)
Commodity: Tungsten, Copper, Silver, Zinc
Lat, Long: 38.62472, -114.72861
Map: View on Google Maps
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.
Schwartz Tunnel MRDS details
Primary: Schwartz Tunnel
Secondary: NBMG Sample Sites 807, 808, 809
Secondary: Ad, Mdm Claims
District: Patterson District; Patterson Pass District; Cave Valley District; Geyser 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.

Comment (Deposit): SOME OF THE VEIN MATERIAL ON THE DUMP FROM ADIT ABOVE TUNNEL LOOKS PEGMATITIC WITH COARSE WHITE MICA AND COARSE TERMINATED QUARTZ CRYSTALS IN VUGS. BELOW THE ADIT DUMP IS PIOCHE SHALE. ADIT ABOVE TUNNEL DISPLAYS REPLACEMENT HORIZON IN ONE OF THE BASAL LIMESTONE UNITS OF PIOCHE SHALE. THE LIMESTONE IS SILICIFIED AND NOW DISPLAYS A TYPICAL TACTITE MINERAL ASSEMBLAGE OF DIOPSIDE, CALCITE, AND EPIDOTE WITH SOME FLUORITE, PYRITE AND CHALCOPYRITE THROUGHOUT. SPHALERITE IS ALSO PRESENT. THE ALTERED HORIZON AT THE MOUTH OF THE ADIT IS REDDISH-BROWN SILICIFIED LIMESTONE WITH POLKA DOT APPEARANCE FROM ALGAL GIRVANELLA. THIS HORIZON IS CAPPED BY GOSSAN WHICH CAN BE FOLLOWED FOR 100 FT OR MORE TO THE SW. AT THE RIDGECREST SW OF SCWARTZ WORKINGS IS AN OLD SHAFT AND SEVERAL DOZER TRENCHES. THE REPLACED HORIZON RECURS HERE. A COARSE, BLADED, GREENISH WHITE MINERAL (WOLLASTONITE? TREMOLITE?) OCCURS ON THE VEIN SELVAGES.
Comment (Workings): 2 ADITS, 2 SHAFTS, SEVERAL DOZER TRENCHES. IN 1916 ONE TUNNEL EXTENDED N25W WEST FOR 300 FT.
Comment (Location): NEAR CREST OF SCHELL CREEK RANGE 2 MILES NORTH OF PATTERSON PASS. . UTM IS TO ONE OF SEVERAL WORKINGS ON THE PROPERTY
Comment (Geology): LIMEY SHALE AND LIMESTONE LOCATED 100 FT. ABOVE THE TUNNEL IS ALTERED TO TACTITE & A STOCKWORK OF QUARTZ VEINS CONTINOUSLY OUTCROP WITH A STRIKE OF N70E AND DIP OF 13SE. SOUTHWEST OF THE TUNNEL PYRITE AND CHALCOPYRITE OCCUR IN VEINLETS, PODS, AND REPLACEMENT OF ALGAL SPHEROIDS WITHIN THE REPLACED HORIZON. GOSSAN IS ABUNDANT IN THE DUMP MATERIAL. THE SWARTZ TUNNEL IS AT OR NEAR THE BASAL CONTACT OF THE PIOCHE SHALE WITH THE PROSPECT MOUNTAIN QUARTZITE
Comment (Development): MOST RECENT CLAIM STAKING IN 1979. SILVER PROSPECT IN 1918

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.
