Comments on the workings information

  • Mined By Block Caving; The San Manuel Fault Divided The Original Cylindrical Ore Body Into Two Halves The Upper Half Being The Kalamazoo Ore Body And The Lower Half The San Manuel Ore Body; Displacement Approx. 8000 Ft

Comments on other economic factors

  • Update--The Development Schedule Has Been Revised Because Newmont Has Recently Released Reserve Figures For San Manuel And Kalamazoo Ore Bodies That Are Smaller Than The Reserve Figures Known At The Time Of The Original Evaluation, Resulting In A Shorter Mine Life. At The Present Mine Rate At San Manuel Mine Life Will End During Second Half Of 1992. Kalamazoo Mine Due To Begin Operating In 1989, But Production Will Not Be Significant Until 1993 When San Manuel Deposit Exhausted. For This Evaluation Kalamazoo Mine Operation Does Not Commence Until 1993. The Open Pit Mine Has A Life Of About 7 Yrs As Of Jan 1988: The Mine Will Produce About 22,500 Mtpy Cu. The Underground In-Situ Leach Operation Will Produce Another 22,500 Mtpy Cu For 7 Yrs (As Of Jan 1987), Then Production Will Double For Another 10 Yrs (Up Thru 2004)

General comments

Subject category Comment text
Deposit The Property Was Visited On March 17, 1978. Updated May 1983. Property Updated Sep 1988 Also Includes Msha.Dbf #0200842 - San Manuel Mill And #0202318 For The Kalamazoo Property. When Kalamazoo Property Is Split Off Add This Msha.Dbf # To Mines Id And Respondent Id In Mils. The Evaluator Has Made The Assumption That The San Manuel Kalamazoo Orebodies Will Be Treated As One Ore Deposit Using The Same Mining Method And The Existing Facilities. The Properties Have Been Combined Into One File. Matrix 1 Refers To The San Manuel Orebody And Matrix 2 Refers To The Kalamazoo Orebody. The Smelter And Refiner Are On Site. Mils Point Of Reference Is Production Shafts At Mine
Deposit Mineralization Is Associated With Intrusion Of Late Cretaceous-Early Tertiary Monzonite Porphyry And Mineralization Occurs In Both The Porphyry And The Pre Intrusive Rocks. Ore Body Has Two Main Parts (Created By Faulting Of Original Orebody) Separated By A Zone Of Scarce Sulfides. At Depth The Two Parts Converge. San Manuel Fault Divided The Original Cylindrical Ore Body Into Two Halves, The Upper Kalamazoo And The Lower San Manuel Ore Bodies, Displacement About 8000 Ft. (Sandbak L A, and Alexander G H, 1995)
