Arizona Mine

The Arizona Mine is a silver and tungsten mine located in Pershing county, Nevada at an elevation of 6,499 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): SILVER ORE OCCURS IN FLAT-LYING QUARTZ VEINS 40 TO 50 FEET ABOVE BASAL CLASTICS IN NORTHERN PART OF THE MINE. VEIN AVERAGED ABOUT 2 1/2 FEET THICK. IN MUCH OF THE ORE, THE METALLIC MINERALS ARE MINUTE PARTICLES DISSEMINATED THROUGH BANDS OF QUARTZ ARGENTITE (PRINCIPAL ORE MINERAL) APPEARED AS GREENISH STAINS OR SOOTY SPOTS. SCHEELITE OCCURS AS SMALL IRREGULARLY SPACED SHOOTS ASSOCIATED WITH STRINGERS AND PODS OF CALCITE AND QUARTZ ALONG EDGES OF OLD STOPED AREAS OF SOUTHERN WORKINGS. THE VEIN HAS BEEN OFFSET DOWNWARD IN A SERIES OF STEPS FROM EAST TO WEST. TWO OTHER POST-MINERAL FAULTS FORM BOUNDARIES TO THE LIMESTONE BLOCK CONTAINING THE VEIN.; MODEL NAME COULD ALSO BE: POLYMETALLIC VEINS.

Comment (Workings): THE VEIN WAS DEVELOPED FROM 2 LOCATIONS ABOUT 1/4 MILE APART.

Comment (Geology): FLAT QUARTZ VEINS FOLLOW BEDDING IN PRIDA, SHALY, CARBONACEOUS, LIMESTONES NEAR CONTACT WITH KOIPATO RHYOLITE PORPHYRY. QUARTZ VEINS CONTAIN PYRITE, SCHEELITE, JAMESONITE, SILVER HALOIDS, COPPER CARBONATES.

Comment (Deposit): MOST WORK DONE AT NORTH HALF IN EARLY PERIOD WITH ESTIMATED PRODUCTION OF $5 MILLION TO $13 MILLION. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV

Comment (Deposit): THIS RECORD HAS BEEN MERGED WITH M060350, WHICH HAS BEEN DELETED.

Comment (Location): UTM TAKEN AT SOUTH HALF OF MINE.

Comment (Production): CUMULATIVE FIGURES LINES 1-5 REPRESENT PRODUCTION FOR ENTIRE DISTRICT. NO PRODUCTION FIGURES AVAILABLE FOR PERIOD 1861-1866, OR 1949-1959. CUMULATIVE FIGURES LINE 6 REPRESENTS PRODUCTION SPECIFIC TO THE ARIZONA MINE.

Comment (Development): ACTIVELY WORKED FOR SILVER UNTIL ABOUT 1880, AND WORKED ON A SMALL SCALE TO 1965. THE NORTHERN HALF WAS WORKED IN THE EARLY YEARS, THE SOUTHERN HALF LATER. TUNGSTEN WAS DISCOVERED IN 1919. ; ECON.COM: SEVERAL MILLION DOLLARS WORTH OF ORE WAS MINED.
