Silver Queen Mine

The Silver Queen Mine is a copper, silver, molybdenum, and gold mine located in Pinal county, Arizona at an elevation of 4,167 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: National Forest
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): Property Is Also Under USGS Mrds Id No. W002674. Commodities Presently Produced Are Copper, Silver And Gold. Ore Was Mined And Milled From 1938-1945 And 1950-1952. Manganese Minerals Are Present In The Deep Vein Ore Bodies The No. 9 Shaft Is The Only Shaft Used. Its Location Is From Information Taken From Pay Dirt And Petersons Mf-253 Development Schedule Based On The Size Of The Deposit, A Major Mine And Plant Development Program Was Initiated In 1969. Limestone Densities Are Assumed. Ore Body Length And Width Limestones Are Estimated. Present Production Is From The Martin And Escabrosa Limest The Magma And Koerner Veins Were Phased Out In 1950 Due To Economic Problems With Ventilation, Cooling And Ore Grade Deep Portions Of The Veins. Swell Factor Is Based On An As Value Of 65 %. A Form Of Underhand Cut And Fill Mining Is Presently Used. This Mining Method Was Adopted From The Su Operations Of The International Nickel Company Of Canada. Production, Service And Supplies For The Mine Are Handled The No. 9 Shaft. Ultimate Hoisting Capacity Of The No. 9 S Is 4000 Tpd Of Ore And 300 Of Waste From 6000 Feet. Cost Related Comments From April 1969 To August 1973 A Major Expansion Program W Undertaken. Total Capital Expenditure Exceeded 70 Million Including All Direct And Indirect Costs. Key Elements Of T Program Were: A 4823 Ft Deep, 22 Ft Diameter Concrete Line A 9200 Ft Long, 12.5 Ft Diameter Bored Adit Connecting Sha No. 9 To Surface Yard Facilities And The Concentrator. An Ground Development Program To Prepare Additional Facilites Increased Mining Tonnage. Expansion And Modernization Of T Concentrator To Process 4200 Tpd Of Ore. Conversion Of The Surface Plant And Mine Electrical System From 25 Hz To 60 A New Hoist Plant. New Air Compressors, Electrical And Mec Repair Shops, Warehouse, Office And Changeroom Facilities Shaft No. 9. Mine Cooling Capacity Was Raised To 6300 Tons (See Murray) Total Direct Mining Costs In 1976 Were 2.39 D Less Per Ton Than In 1973. Property Update Sept. 1991. Mils Location Is Neversweat (500-Foot) Tunnel Portal. Main Production And Service Shaft, No. 9 Shaft, Is Located At N331816 Lat, W1110403 Long, In Sec 32, R13e, T1s, Gila & Salt River Pm. Ore Is Hoisted Up This Shaft From Deep Levels To Neversweat Level. Ore Is Then Trammed 2,740 M To Portal And Another 670 M On Surface To Concentrator. 1979-82 & 1990 Production From Az Dept Of Mines & Min. Res. Special Reports - Primary Copper Industry Of Arizona. Mine Closed In 1982, And Was Allowed To Flood In 1986. In 1989, Mine Dewatering Began And Was Completed In Early 1990. Production Started In Late July At A Level Of 907 Mtpd Ore. By End Of 1991, Production Level Will Reach 1360 Mtpd Ore.

Comment (Reserve-Resource): Other Name:Silver Queen Or Magma Mine Reopening With 1,500,000 Mt Measured Reserves At 6.8% Cu.

Comment (Economic Factors): Other Name:Silver Queen Or Magma Mine Reopening With 1,500,000 Mt Measured Reserves At 6.8% Cu. Labor Recs Based On Mine And Mill At Planned Capacity After 1991.

Comment (Deposit): The Magma Mine at Superior: Complex Vein Splits Forming Stockworks, With Ore Shoots, Alone Faults And Fissures. Main Ore Body E Of W Dipping Main Fault. Central Ore Bodies Are Complex Ore Shoots E Of Main Body. Farther E And Up In Section Are Replacement Beds In Lower Devonian Linestone, 10-90 Ft Width Of Ore, 25 Ft Average. In The Central Ore Bodies, Above The 2550 Ft Level, Zinc Exceeds Copper. Below 2550 Ft, Copper Dominates

Comment (Development): Originally Called The Silver Queen, 1875-1909. Magma Copper Company Began Operating 1910 Minor Production Until 1911, When Owned By Lake Superior And Arizona Mining Company

Comment (Geology): The Magma Mine at Superior: Mineralization Associated With Diorite Porphyry Intrusive Period, Although Little Intrusive Rock Is Present Here. Major Intrusive Is 2 Miles N. At Silver King, Faults Are Premineralization, And Faults Continued To Move During The Short Period Between Porphyry Intrusion And Mineral Deposition. Ore Deposition Was Mesothermal, And Mineralogy And Occurrence Of Ore Is Similar To Deposits Of Butte, Montana. The Magma Is Not Similar To Nearby Porphyry Copper Deposits As There Is Little Disseminated Ore In Porphyry Host Rock, But The Age Of Mineralization Is The Same As Nearby Deposits Such As The Globe And Miami, Approximately 60 M.Y.

Comment (Workings): 8 Shafts. Deepest Mine In The State. 36 Levels, With Levels Every 100 Ft In Upper 2000 Ft Every 200 Ft Down To 4800 Ft. Workings Diminish In Thickness To The East, And Are Mainly Between The 3000 Ft And 4000 Ft Levels. Length Of Workings Estimated

Comment (Deposit): The Magma Mine at Superior: Vein Occurs Within A Strike Fault Zone That Has Brecciated The Wall Rocks Contact And The Lower Beds Of The Limestone. Most Productive Gold Horizon Along The Faults Is Within The Limestone, 10-20 Feet Above The Limestone-Quartzite Contact. All Mined Ore Has Been Oxidized

Comment (Development): Claims Include Golden Eagle And 5 Adjacent Claims; Worked In 1880'S By Gem Mining Co. As The Golden Eagle Mine; Other Owners/Operators: Lake Superior And Arizona Mining And Smelting Co., Superior Arizona Mining Co., Sam Herron And Con Laster

Comment (Geology): Although There Are No Surface Intrusives, Mineralization Is Associated With Cret-Paleo Intrusive And Faulting Episodes

Comment (Workings): Workings Include Vivian Shaft (279 Ft Deep), Anderson Tunnel (200 Ft), Carlton Tunnel (2000 Ft), Holt Tunnel And Inclined Shaft (1800 Ft Deep); The Anderson Tunnelis Located About 100 Ft North Of The Carlton, Upslope; The Holt Tunnel Is About 1200 Ft North Of The Anderson At About The Same Elevation; The Holt, Anderson, And Carlton Interconnect Underground.
