Black Metal Mine

The Black Metal Mine is a silver, manganese, and iron mine located in Lincoln county, Nevada at an elevation of 6,362 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 (Workings): DAY SHAFT, NEAR VERTICAL WITH LEVELS AT ABOUT 75-FT INTERVALS TO THE 1200 FT LEVEL. AT 300 LEVEL, THE SHAFT MADES CONNECTION WITH A SURFACE TUNNEL AND AT THE 900 LEVEL WITH A DRIFT FROM THE BOTTOM OF THE JACK RABBIT INCLINED SHAFT. STOPING EXTENDS FROM SURFACE TO 900 FT LEVEL.

Comment (Commodity): PROVIDED FE-MN-CAO FLUXING ORE FOR EARLY SMELTERS

Comment (Location): UNSURVEYED AREA. DAY SHAFT IS ABOUT 2000 FT SOUTH OF THE JACKRABBIT INCLINE. UTM IS TO DAY SHAFT OF THE BLACK METAL MINE ; INFO FROM LAND.ST :(1972)

Comment (Production): SHIPPING 50 TPD IN 1919, 1920, 1921; SHIPPING 1900 TONS/MONTH MN ORE IN 1926 (15-20% MN, 3 OZ/T AG, 0.8% PB) TOTAL PRODUCTION WAS PROBABLY 2.5 TO 3.0 MILLION DOLLARS WORTH OF ORE.

Comment (Deposit): CHIMNEY AT 3 HORIZONS IS KNOWN AS THE A, B AND C BEDS. THE A BED EXTENDS UP FROM PIPE AT 300-FT LEVEL, IS LARGE AND IRREGULAR WITH A FOOTWALL SURFACE STRIKING N65W, DIPPING 15N, STOPED 1-20 FT THICK.

Comment (Development): OPERATED IN 1911-1912 BY DAY-BRISTOL CONSOLIDATED MINING CO; IDLE IN 1913. OPERATED 1919-1927, IDLE FROM 1927-1941

Comment (Deposit): MUCH ORE TAKEN FROM THE "A" BED STOPE BETWEEN 200 AND 400 LEVELS, FOLLOWING A CERTAIN LIMESTONE BED FOR 600 FT ON DIP, IRREGULARLY REPLACING IT FOR 50 FT OR MORE IN WIDTH. LARGEST ORE BODIES WERE STOPED FROM THE SURFACE TO THE 3RD LEVEL AND BETWEEN THE 4TH AND 9TH LEVELS. LOWER ORE BODIES OCCURED ALONG A N4SE FISSURE WHICH DIPS SE FROM 4TH TO 6TH LEVEL BUT BELOW THE 6TH LEVEL IT DIPS AN AVERAGE OF 50NW. THE ORE SYSTEM CONSISTS OF A VERTICAL PIPE FROM WHICH "ORE BEDS" EXTEND OUT LATERALLY AT 3 HORIZONS INTO THE GENTLY-DIPPING LIMESTONES THAT ENCLOSE THE PIPE. AG-PB ORE OCCURRED IN THE CENTER OF THE PIPE WITH EXTERIOR ZONES PROGRESSIVELY HIGHER IN MN AND LOWER IN PB AND AG. THE ORE PIPE OR CHIMNEY OCCURS ALONG A VEIN (N25E) WHICH IS A BELT OF BRECCIATED ROCK 25 FT THICH WITH ANGULAR BLOCKS OF LIMESTONE COUNTRY ROCK ENCLOSED IN COARSE WHITE CALCITE. THE VEIN IS IRREGULAR IN THICKNESS, BULGING OUT WHERE IT CROSSES CERTAIN BEDS. THE REPLACEMENT BEDDED ORE THAT MAKES OFF FROM THE
