The Hilltop Mine is a tungsten mine located in Pershing county, Nevada at an elevation of 6,939 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.

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.

Comment (Deposit): THIS RECORD HAS BEEN MERGED WITH RECORDS D001221 AND M060217, WHICH HAVE BEEN DELETED.
Comment (Deposit): THIS RECORD AND DELETED M060217 HAVE DIFFERENT LOCATIONS, BUT THE SITE NAME AND OTHER INFORMATION IS VERY SIMILAR. M060217 STATED THAT "UTM LOCATION IS ESTIMATED, UNCERTAIN". M060217 GIVES ONLY JOHNSON AS A REFERENCE. JOHNSON, STAGER AND TINGLEY, AND UNPUBLISHED NBMG FIL SHOULD BE CHECKED TO VERIFY LOCATION. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
Comment (Deposit): MONZONITE ENGULFS SEVERAL PENDANTS OF METAMORPHIC ROCKS (SLATE, SCHIST, TACTITE) WHICH STRIKE N70W, DIP 60-75 NE. EXPOSURES ARE POOR DUE TO SURFACE COVER. 3 SMALL PENDANTS ARE KNOWN. THE NORTHERN ONE IS ABOUT 13 FT WIDE AND CONSISTS OF BIOTITE SCHIST AND A BED OF TACTITE 4.5 FT WIDE CONTAINING SOME SCHEELITE. A SECOND PENDANT ABOUT 450 FT TO THE SOUTH IS 18 FT WIDE AND CONSISTS OF TACTITE INTERBEDDED WITH SCHIST. IT IS EXPOSED FOR A STRIKE LENGTH OF 50 FT BUT IS CUT BY GRANITE AT 2 PLACES. A THIRD PENDANT IS 13 FT WIDE AND IS APPROXIMATELY ON STRIKE WITH THE SECOND PENDANT BUT IS SEPARATED FROM IT BY 200 FT OF GRANITE. THE ORE EXPOSED IN THESE PENDANTS CONTAINS 0.5 TO 0.75 % WO3.
Comment (Workings): ADIT WITH 2 SHORT CROSSCUTS, INCLINED SHAFT ABOUT 35 FT DEEP, SEVERAL OPEN CUTS, PITS, AND TRENCHES.
