The Long is a tungsten mine located in Pershing county, Nevada at an elevation of 4,400 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.

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 (Location): NW PART OF THE DISTRICT
Comment (Development): LOCATED AND PROSPECTED DURING WW1, BUT NO ORE SHIPPED. RELOCATED IN 1938, AND WORKED DURING 1942-44 AND 1952-54(?). PROSPECTED BY WILLIAM CHAMBERS AND J.S. BEDFORD DURING 1917-1918 WITH NO PRODUCTION. RELOCATED BY WAYNE STOCKER IN 1938 AND AGAIN BY E.T. LONG AND W.E. MEISSER IN 1941. IN 1942 IT WAS LEASED TO THE RARE METALS CORP. OF LOVELOCK, AND WAS OPERATED BY THIS COMPANY DURING 1942 AND 1943. IT WAS OPERATED AGAIN FOR SHORT PERIODS IN 1956, 1972-1973 AND IN 1978-1979. THE LAST OPERATOR OF RECORD WAS AARON MINING CO. INC., WHO MINE ABOUT 5000 TONS OF ORE AND TREATED IT IN THE OLD TOULON MILL, SW OF LOVELOCK. NO ACTIVITY AT TIME OF EXAMINATION IN 1985.
Comment (Production): MINE WORKED FROM 1942-44, AND 1952-1954(?). TWO MAJOR OREBODIES MINED WERE 130-200 FT LONG, 6-7 FT WIDE, MINED TO A DEPTH OF 35-55 FT WITH ORE AVERAGING ABOUT 0.6 % WO3.
Comment (Geology): MINE DEVELOPED ALONG THE MARBLE-HORNFELS CONTACT ON TWO ORE BODIES. THE S ORE BODY, IN THE SYNCLINE TROUGH, WAS MINED ALONG BOTH LIMBS; SCHEELITE MINERALIZATION DECREASED AFTER 130 FEET ON W LIMB, AND 125 FEET ON E. THE N ORE BODY, ON THE W LIMB, MINED FOR ABOUT 200 FEET. SOME ORE ALSO FOUND ALONG MARBLE-MONZONITE CONTACT
Comment (Deposit): SCHEELITE-BEARING BODIES OF TACTITE OCCUR ALONG CONTACT BETWEEN MARBLE AND MONZONITE AND ALONG CONTACTS BETWEEN MARBLE AND OVERLYING HORNFELS, A FEW TENS OF FEET EAST OF MONZONITE INTRUSIVE CONTACT. SEDIMENTARY ROCKS FOLDED INTO ASYMMETRICAL SYNCLINE; W. LIMB INTRUDED BY MONZONITE. TWO ORE BODIES DEVELOPED ALONG MARBLE-HORNFELS CONTACT. SOUTH ORE BODY IN TROUGH OF SYNCLINE WAS MINED ALONG BOTH LIMBS, BUT SCHEELITE MINERALIZATION DECREASED AFTER 130 FT ON W. LIMB, AND 125 FT ON E. LIMB. NORTH ORE BODY, ON W. LIMB, WAS MINED FOR ABOUT 200 FT. TWO IRREGULARLY SHAPED PODS ALONG MARBLE-MONZONITE CONTACT CONTAINED ENOUGH SCHEELITE TO YIELD 150 TO 200 TONS OF ORE. URANIUM IS PRESENT IN VERY IRREGULAR, SPOTTY, OCCURRENCES IN THE TACTITE ZONE.
Comment (Workings): SURFACE CUTS AND PITS, UNDERGROUND DEVELOPMENT OF 62O DRIFTS AND ADITS.

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.
