Comments on the production information

  • 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.
  • 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.

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