Pflum Mine

The Pflum Mine is a silver, antimony, and lead mine located in Pershing county, Nevada at an elevation of 6,001 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): A QUARTZ-ANTIMONY VEIN THAT RANGES FROM 4 TO 12 INCHES WIDE CUTS THE LIMESTONE WITH SEVERAL BARREN FAULTS CLOSELY PARALLELING THE VEIN. THE VEIN IS OFFSET BY A SUBHORIZONTAL BEDDING-PLANE FAULT, GIVING THE APPEARANCE OF TWO VEINS. STIBNITE OCCURS AS SMALL PODS AND SINGLE CRYSTALS IN QUARTZ. SPHALERITE AND PYRITE ARE ASSOCIATED WITH THE ANTIMONY MINERALS BUT ARE MORE COMMON IN THE LIMESTONE ADJACENT TO THE VEIN. GREEN TO BLUE MELANTERITE COATS SOME OF THE VEIN MATERIAL. THE VEIN FILLS PREMINERAL FAULT FISSURE IN RHYOLITE AND LOWER MEMBER PRIDA FORMATION. ORE VALUES DECREASED WITH DEPTH. ORE HIGH IN SILVER FOUND NEAR THE SURFACE.; MODEL NAME COULD ALSO BE: POLYMETALLIC VEINS.

Comment (Workings): THE MINE IS DEVELOPED BY MORE THAN 1000 FT OF WORKINGS, INCLUDING TWO ADITS, AN INTERMEDIATE 15-FT LEVEL, AND SOME STOPING.

Comment (Geology): ORE VEIN FILLS PREMINERAL FAULT FISSURES OF SMALL DISPLACEMENT. VEIN BROKE INTO NUMEROUS VEINLETS ALONG BEDDING PLANES AND FRACTURE CLEAVAGES IN OVERLYING TUFFACEOUS SANDSTONE (BASAL UNIT OF THE PRIDA FORMATION), WHICH IS OVER LAIN BY AN IMPERVIOUS THIN SHALY LIMESTONE, TRAPPING THE MINERALIZED SOLUTIONS. ORE VALUE DECREASES WITH DEPTH. STOPING DONE UP DIP. STIBNITE OCCURS IN SMALL PODS AND SINGLE CRYSTALS IN QUARTZ
