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): Original Evaluation Done By R.L. Baer, Revision Done Nov 1978, Update Done December 1983. The Following Data Sets Have Been Eliminated From The Data Base Because They Were Unnecessary On Account Of Ore Depletion And The Subsequent Closure Of The Operation: R, Q1, Q2, Q9, D1, I, U, K1, F1, K2, F2, Pa, Ya, T1, Pb, Yb, T2, D9. Property Updated Jul '87.

Comment (Production): History: Mining Discontinued In 1975. Mill Sold, Dismantled & Shipped To The Philippines. Leach Discontinued In June 1982 Due To Ore Depletion. Newmont Mining Spun Off All Its Copper Mining Operations Into One Company - Magma Copper Company In 1986. The Precipitation Plant At Copper Cities Was Permanently Shutdown In June 1982 And Is No Longer Considered A Production Unit.

Comment (Commodity): Pyrite: Chalcopyrite Ratio Increases With Depth From 1.2 To 9 In He Ore Body To 4 To 16 Below The Ore Body. The Best Turquoise Is A Hard Medium Blue Stone, Without Inclusions, And Fracture Free. Some Of The Turquoise Is Soft And Pale And Locally Enhanced And Stabilized For Sale.

Comment (Deposit): Dimensions Of Length And Width Are Dimensions Of The Stock; Deposit Is 3000 M Long, 300 M Thick, 900 M Wide And 30 M Deep On Average. Turquoise Has Been Produced From The Oxidized Portions Of The Deposit.

Comment (Development): Previous Owners Included Gerard Mining Co, Lost Gulch Mining Co, Miami Copper Co, Louis D'Or Gold Mining Co (1912), Louis D'Or Mining & Milling Co, Porphyry Reserve Copper Co (1928), Copper Cities Mining C O (A Subsidiary Of Miami Copper Co, 1943), Cities Service Co. ; Econ.Com: Turquoise From This Mine Has Been Marketed Worldwide.

Comment (Geology): Richest Part Of Ore Body Is In Quartz Monzonite Along S Side Of Granite Porphyry. Granite Porphyry Is Associated With Chultze Granite.

Comment (Production): Early Production Was Mostly From The Bonanza, Badger, And Cedar Tree Claims SW Of Pit; Later Production Was Mostly From The Louis D'Or Shaft Just N Of Pit. Most Recent Production Is From Pit. The Sleeping Beauty Property Has Been A Steady Producer Of Turquoise For Many Years.

Comment (Workings): Underground Workings Now Included In Open Pit. See Deposit Descri Ption For Approx. Size Of Pit.

Comment (Deposit): Host rock is quartz monzonite intruded by granite porphyry. (Peterson, 1954)
