Forge Mine

The Forge Mine is a tungsten mine located in Pershing county, Nevada at an elevation of 4,449 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.

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 (Deposit): AT FORGE MINE ONE LONG ADIT AND TWO SHORTER ONES WERE DRIVEN TO EXPOSE THE MOST PROMISING TACTITE BODIES, BUT NO ORE WAS FOUND. LIMESTONES CROPPING OUT ON FORGE PROPERTY ARE PARTIALLY REPLACED BY GARNET TACTITES AT A FEW POINTS ADJACENT TO THE CONTACT WITH THE INTRUSIVE. ; INFO.SRC : 1 PUB LIT

Comment (Development): ADITS WERE DRIVEN TO EXPOSE THE MOST PROMISING TACTITE BODIES, BUT NO ORE WAS FOUND. THE FORGE MINE WAS THE FOCUS OF A SHORT-LIVED MOLYBDENUM EXPLORATION PROJECT IN THE LATE 1960'S. THE PROPERTY IS -NOW HELD (1983) BY GENERAL ELECTRIC CO. (UTAH INTERNATIONAL) W-HO ALSO CONTROLS THE MAJOR TUNGSTEN PROPERTIES DIRECTLY TO THE- NORTH.

Comment (Deposit): SCHEELITE MINERALIZATION OCCURS IN IRREGULAR ZONES IN LIMESTONE AND TACTITE BEDS. AT LEAST 6 SEPARATE NARROW LIMESTONE BEDS HAVE BEEN IDENTIFIED WITHIN THE LARGELY HORNFELS SECTION. SHORT SEGMENTS OF 2 OR 3 SEPARATE LIMESTONE BEDS ARE IN CONTACT WITH THE MARGINS OF THE STOCK WHERE EXPOSED IN THE GULLY IN THE CENTER OF THE PROPERTY. THESE BEDS HAVE BEEN CONVERTED TO MASSIVE GARNET TACTITE CONTAINING SCATTERED SCHEELITE. ON THE WEST SIDE OF THE CANYON, WHAT APPEAR TO BE OLDER MINE WORKINGS EXPLORE AN AREA OF QUARTZ VEINS IN THE GRANODIORITE. THE MOST EXTENSIVE MINE WORKINGS ARE EAST OF THE CANYON ON THE SOUTHERN POINT OF A SMALL SPURLIKE HILL OF HORNFELS WHICH JUTS AWAY FROM THE RANGE AT THIS POINT. A LONG DRIFT ADIT EXPOSES WEAKLY SILICIFIED ROCK WITH PODS OF GARNET WHICH HAVE FORMED ALONG A LIMESTONE BED FROM 10 TO 15 FT THICK. SCHEELITE MINERALIZATION IS VERY SPARSE WHERE EXPOSED IN THE BACK OF THE DRIFT. A FOURTH LIMESTONEBED, WITH WEAK SILICATION CROPS OUT EAST OF THE ADIT AND 2

Comment (Deposit): MORE UNALTERED LIMESTONE BEDS CROP OUT FURTHER TO THE EAST ON THE LOWE FLANK OF THE HILL.

Comment (Workings): ONE LONG ADIT AND TWO SMALLER ONES

Comment (Geology): SCHEELITE MINERALIZATION OCCURS IN IRREGULAR ZONES IN LIMESTONE AND TACTITE BEDS

Comment (Location): ON SE FLANK OF EUGENE MOUNTAINS ABOUT A MILE SOUTH OF THE OLD TUNGSTEN TOWNSITE.

Comment (Production): IT IS POSSIBLE THAT A SMALL TONNAGE OF ORE WAS MINED FROM THIS PROPERTY AND SHIPPED TO THE MILLS AT TUNGSTEN, BUT -NO RECORDS EXIST TO CONFIRM THIS.
