SMELTER ON SITE, OPENED 1922, PRODUCES STONS CU/YEAR.ALL PREVIOUS DATA FROM SUTULOV,1975. 1975-PLANS ARE CURRENTLY UNDERWAY TO MECHANIZE EXTRACTION AT EL TENIENTE AT A COST OF $50 MILLION. A SYSTEM WILL BE IN- STALLED WITHIN THE MINE TO HANDLE HARD CU BEARING ORE. IN 1974 PRODUCTION OF BLISTER AND REFINED CU WAS 220,000 TONS. DUE TO DECLINING ORE GRADES A CHANGE IN THE PRESENT BLOCK CAVING METHOD IS UNDER STUDY FOR A METHOD MORE TECHNICALLY A ECONOMICALLY FEASIBLE FOR MINING THE PRIMARY ZONE. EXPANSION IN 1978 WITH INSTALLATION OF A PRIMARY UNDERGROUND CRUSHING STATION, CAPABLE OF REDUCING 30000 MTPD OF ORE. EXPANSION STUDY AT EL TENIENTE IS BEING DONE BY MCKEE WEST- ERN KNAPP ENGINEERING. EXPANSION DESIGNED TO MAINTAIN MINES CURRENT CAPACITY OF 275,000 TONS/YEAR. THE HEAD GRADE FOR THE EL TENIENTE ORE IS 1.37 PER CENT COPPER AND .023 PER CENT MOLYBDENUM. IN MARCH 1978, CONTRACTS FOR A 25-YEAR DEVELOPMENT AND OPERATIONS PLAN WERE BEING ESTABLISHED. INVESTMENT IN THE MINE OVER THE NEXT 25 YEARS MAY REACH 1 BILLION DOLLARS.
