  • General form IRREGULAR

Controls for ore emplacement

  • Tactites At Contact Of Quartz Monzonite And Ferrobamba Limestone - Cross Folds Superimosed On Regional Fold Pattern Ore Containing More Than 3% Cu Is Always In The Polymineral Tactite Rather Than In Garnetite Or Epidotite. The Favorable Intrusive Quartz Monzonite Averages About 1.5 To 2% Cu. Ores Along Fracture Zones Average About 1% Cu.

Comments on the reserve resource information

  • CSI (COPPER STUDIES) 4/20/73 REPORTS 1.75 MIL TONS 3.4% CU
  • POTENTIAL RESOURCES ESTIMATED BY THE REPORTER ON 2/73 BASED ON DESCRIPTIONS IN AN UNPUBLISHED REPORT BY FRANK SIMONS USGS. MINERALIZED ZONE 700 X 500 X 70 METERS. ASSUMING ONLY ONE THIRD OR MORE OF THIS VOLUME WOULD BE ORE, THEN THE POTENTIAL RESOURCES WOULD EXCEED 25 MIL MET TONS. GOLD POTENTIAL HAS NOT YET BEEN EVALUATED FOR CU SKARNS.

Comments on the workings information

  • THE MINERALIZED AREA IS 700 M BY 500 METERS AND MINERALIZED ZONE HAS BEEN PENETRATED TO 70 METERS

Deposit BESIDES CHALCOBAMBA COPPER DEPOSIT, TWO OTHER SMALL DEPOSITS WITHIN THE FERROBAMBA REGION ARE THE CHARCAS 2 KM SOUTHWEST OF CHALCOBAMBA AT AN ALTITUDE OF 4600 M. THE ORE BODIES ARE PARALLEL TO THE BEDDING OF FERROBAMBA LIMESTONE, WITH ORES AVERAGING ABOUT 5% CU. WITH RESERVES OF ABOUT ONE MIL TONS. THE OTHER DEPOSIT IS THE SULFOBAMBA 3 1/2 KM W. NW OF CHARCAS AT AN ALTITUDE OF 4600 M AND IN THE LOWER PART OF FERROBAMBA LIMESTONE. THE SULFUR CONTENT OF THE ORE IN SULFOBAMBA IS HIGHER THAN THAT OF THE OTHER FERROBAMBA DEPOSITS. TOTAL RESERVES AND RESOURCES ARE ESTIMATED AT ABOUT 3 MIL TONS ABOUT 2.5% CU.
