The Inspiration is a copper and molybdenum mine located in Gila county, Arizona at an elevation of 3,707 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.

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.

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): Miami And Inspiration Are Part Of Same Orebody, Though Owned By Different Companies. Miami Is E Of Inspiration. Former Operators Include Inspiration Copper Co (1908) On Joe Bush, Scorpio And Bulldog Shafts And Woodson, Columbia, Taylor Clipper, And Bulldog Adits; Live Oak Development Co. Consolidated In 1912 To Form Inspiration Consolidated Copper Co.; Keystone Copper Co (1915); Miami Copper Co., And Tennessee.
Comment (Workings): Old Miami Underground Workings, Open Pit. Miami East Under Development (1980) With Planned Production Of 2000 T/Day. In 1989, Miami Was An Open Pit Cu Oxide Mine With Heap And Dump Leaching, As Well As Solvent Extraction.
Comment (Geology): Supergene Enrichment, Much Of Which Occurred Before Most Of the Faulting And Tilting In Area (Concentration)
Comment (Geology): Schistosity (N50e, Steep Se) Controlled Instrusion Of Schultze Granite And Hydrothermal (Solutions) That Deposited Primary Sulfide Minerals [Ore Control]
Comment (Commodity): Rhenium Occurs In Molybdenite.
Comment (Deposit): Supergene Enriched Zone Averages 200 Ft Thick. Higher Grade Mineralization Occurs As Bands Along Miami And Pinto Faults Between Joe Bush And Bulldog Faults. Molybdenite Was Last Stage Of Hypogene Mineralization.
Comment (Reserve-Resource): Miami stockpile is 433 million mt ore grading 0.38% Cu, but the anticipated recovery rate is only 1.5%. That works out to 45 Kt Cu, and the table states only 25 Kt. (Freeport 2009 Form 10-K) http://www.fcx.com/ir/downloads/FCX_2009Form_10-K.pdf
Comment (Names): Location Miner Haight Group ID:10209674 and Boston Miami Copper Co Claims ID:10136998 may be possible duplicates to Cyprus Miami
Comment (Geology): Geometry Data Given Pertains Only To The Original Inspiration Consolidated Copper Co. Pits. For Bluebird And Ox Hide Geology, See Sequence Numbers 0040070007 And 0040070060, Respectively. However, The Figures Given For The Area Disturbed Include The Disturbed Areas For The Bluebird And Ox Hide Pits.
Comment (Production): In Jan. 1984, The Crusher And Concentrator Were Permanently Shutdown. In 1989, The Leach Precipitating Plant Was Permanently Shutdown. At This Time (5/92), All Production Is From The Leach/Sx-Ew Operation. 1982 - 1992 Production From Arizona Dept. Of Mines & Min. Res. Special Reports On Primary Copper Industry Of Arizona 1993 Production From Sec Form 10-K Rept, 12/31/93, P. 7.
Comment (Ownership): Inspiration Consolidated Copper Company Acquired The Bluebird Property For $700,000 Paid In Six Annual Installments And A Royalty Payment Of $0.033/Kg Of Cu Produced Or A Minimum Annual Payment Of $225,000 Up Through 1999. In 1988, Cyprus Purchased The Inspiration Consolidated Copper Company From Its Parent, Inspiration Resources Corp. For $125 Million, Whose Assets Consisted Of All Their Copper Properties, The Smelter, And Copper Rod Plant. Cyprus Minerals Merged With Amax Inc, In November 1993.
Comment (Deposit): Cyprus Miami Properties Consist Of: Live Oak, Thornton, Joe Bush, Willow Springs, Bluebird, And Ox Hide Mines. The Bluebird Copper Property File (Seq. No. 0040070007) And The Ox Hide Property File (Seq. No. 0040070060) Have Now Been Merged (5,92) Into The Inspiration Property File, Now Known As The Cyprus Miami Mine, Because These Three Properties Are Now Mined As One Integrated Mining Operation By Cyprus Minerals.
Comment (Economic Factors): Mine Transportation Cost Included In Mine Op. Cost. Investment Record 017 Is Mine Working Capital Increase In 1992 Due To Increased Stripping. Investment Records 022 And 023 -- Royalty Rate Of $0.033/Kg Of Cu Produced Is Adjusted By 60% ($0.02) Because 60% Of The Average Ore Production To The Dumps Is From The Bluebird Property.
