Eagle Rock Mine

The Eagle Rock Mine is a zinc, antimony, copper, tungsten, and lead mine located in Lincoln county, Nevada at an elevation of 7,201 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 (Workings): 1 ADIT AND 2 OLD SHACKS ON PROPERTY AS WELL AS SURFACE CUTS AND PITS ALONG STRIKE OF THE VEINS

Comment (Geology): MINERALIZATION OCCURS IN 2 QUARTZ VEINS. ONE VEIN IS FE-OXIDE STAINED QUARTZ WITH MASSIVE TO BLADED, FINE TO COARSE GRAINED WOLFRAMITE. THE OTHER IS MASSIVE QUARTZ WITH WOLFRAMITE AND SULFIDES PRESENT

Comment (Location): WEST FLANK OF SCHELL CREEK RANGE IN CAVE VALLEY

Comment (Deposit): WOLFRAMITE AND SOME SCHEELITE OCCUR AS SCATTERED SMALL CRYSTALS WITH LIMONITE AND MN OXIDES IN SEAMS AND VUGS OF 2 QUARTZ VEINS ABOUT 800 FT APART, 2-3 FT THICK, TRACEABLE IN SURFACE CUTS AND OUTCROPS FOR 300-500 FT ALONG STRIKE. ONE VEIN CONTAINS BASE METAL SULFIDES WITH THE WOLFRAMITE, BUT THE OTHER DOES NOT.

Comment (Deposit): Discovery Year: LATE 1920'S (?)
