Johnson-Heizer Mine

The Johnson-Heizer Mine is a antimony mine located in Pershing county, Nevada at an elevation of 4,551 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: Private
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): CONSISTS OF TWO ORE BODIES MINED AT DIFFERENT TIMES. THE SOUTHERN BODY WAS FIRST MINED IN 1916; THE NORTHERN IN 1946. THE DEPOSIT WAS EXPLORED BY TRENCHING FOR 2500 FT ALONG SHEAR ZONE. NO ACTIVITY IN 1985.

Comment (Deposit): FOUND IN 1916. CONSISTS OF TWO ORE BODIES MINED AT DIFFERENT TIMES. THE SOUTHERN ORE BODY WAS FIRST MINED IN 1916. THE NORTHERN ORE BODY WAS NOT MINED TILL 1946. DEPOSIT IS DEVELOPED BY A 264-FT. INCLINED SHAFT FROM WHICH SOME 440 FEET OF DRIFTING AND CONSIDERABLE STOPING WERE DONE. EXPLORED BY TRENCHING FOR 2500 FT. ALONG SHEAR ZONE; SHAFT WAS SUNK ON VEIN TO THE SOUTHEAST. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Deposit): CONSISTS OF TWO ORE BODIES. VEIN VARIES IN THICKNESS FROM 6 TO 25 INCHES, AVERAGING 12 INCHES. STIBNITE OCCURS AS PODS, VEINLETS, AND FINE HAIRLIKE CRYSTALS, COMMONLY IN QUARTZ AND CALCITE STRINGERS. PYRITE PRESENT ALONG EDGE OFUARTZ STRINGERS. STIBNITE ALSO OCCURS ALONG BEDDING PLANES IN THE CONTORTED AND ECCIATED SHALE WALL ROCK. THE STIBNITE HAS BEEN PARTIALLY OXIDIZED TO YELLOW ANDHITE SB-OXIDES NEAR THE SURFACE. VEIN ZONE APPROXIMATELY PARALLELS BEDDING IN SEDIMENTARY ROCKS WITH VEINS BEST DEVELOPED IN QUARTZITE BED.; MODEL NAME COULD ALSO BE: SIMPLE SB.

PYRITE PRESENT ALONG EDGE OF QUARTZ STRGERS. STIBNITE ALSO OCCURS ALONG BEDDING PLANES IN THE CONTORTED AND BRECCIATED ALE WALL ROCK.
