Comments on the production information

  • PLANNED PRODUCTION IS 5120 TPD (1990), OR APPROXIMATELY 1360 TPA IODINE AND 131,000 TPA POTASSIUM NITRATE.

Comments on the reserve resource information

  • TALTAL RESERVES ARE FOR COMBINED YUMBES AND YOLANDA RESERVES.

Comments on development

  • FEASIBILITY STUDY (BY DAVY MCKEE CORP.) COMPLETED IN 1990 SAYS TALTAL IODINE PROJECT FEASIBLE. ; DEV$: 69.2 ; ECON.COM: ESTIMATED OPERATING COSTS ARE PUT AT $30.91 PER TONNE. INITIAL PRODUCTION IS PLANNED IN 1991 AT A LEVEL OF 5120 TPD. ORE WILL BE HEAP LEACHED WITH SEAWATER AND CRUDE IODINE WILL BE RECOVERED BY PRECIPITATION AND SODIUM NITRATE PRODUCED THROUGH PUMPING THE LIQUOR TO SOLAR EVAPORATION PONDS. DEVELOPMENT COSTS ARE FOR THE TALTAL PROJECT (YUMBES AND YOLANDA DEPOSITS). PRODUCTION WILL INITIALLY BE AT THE HIGHER GRADE YUMBES DEPOSIT. ESTIMATED PRODUCTION LIFE IS 14 YEARS FOR YUMBES DEPOSIT.
