The Utah Spur Mine is a silver and gold mine located in Lincoln county, Nevada at an elevation of 7,799 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 (Development): MOST OF THE PROPERTY LIES IN UTAH. ORE WAS SHIPPED PRIOR TO 1921. IN 1983, KINETIC MINERALS ANNOUNCED PLANS TO MILL DUMP MATERIAL AT THE OFER MINE IN UTAH, ACROSS THE STATELINE FROM THE UTAH SPUR. THEY SAID THEY PLANNED TO SEEK MORE PUMPS IN THE AREA, TOO. IT IS UNKNOWN WHETHER OR NOT THEIR OPERATIONS WOULD INVOLVE THE UTAH SPUR OR NEARBY NEVADA PROPERTIES.
Comment (Location): PROPERTY STRADDLES THE NEVADA-UTAH BORDER. ; INFO FROM LAND.ST :1982
Comment (Deposit): VEIN HAS A BOLD STRONG OUTCROP WHICH CAN EASILY BE TRACED FOR 1000 FT. VEIN CONSISTS OF BOTH QUARTZ AND SILICIFIED RHYOLITE OR ANDESITE. MOST OF THE VEIN IS BARREN WITH 2 PLACES MINERALIZED: AT ONE PLACE, AN OPEN CUT EXPOSED A SMALL BODY OF HIGH GRADE SILVER ORE, THE SILVER OCCURRING AS SPECKS AND BANDS OF BLACK SULFIDE (ARGENTITE) IN THE QUARTZ.
Comment (Workings): OPEN CUT, VERTICAL SHAFT SEVERAL HUNDRED FT SE OF OPEN CUT, A SECOND VERTICAL SHAFT, (EACH ABOUT 75 FT DEEP), A CROSSCUT TUNNEL PERHAPS 200 FT LONG (INACCESSIBLE). MOST OF THE WORKINGS ARE ON THE UTAH SIDE OFTHE STATE LINE
Comment (Geology): ANDESITE IS ON HANGING WALL SIDE OF VEIN BUT CONTACT IS NOT WELL-DEFINED EXCEPT WHERE THERE IS EVIDENCE OF FAULTING

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.
