Deposit 1974 ORE MINED WAS 18.6DMST;6.45 DMST OF ORE WAS PROCESSED @ COPPER;103.3M POUNDS COPPER PRODUCED. 50% EXPANSION OF SULFI DUE FOR COMPL. IN 1975. IMPROVED RECOVERY & RETREATMENT OF WILL INCREASE PROD. BY 3%. 1967- EST. 5MMT OF COPPER OXIDE O %. STRIPPING RATIO IS ABOUT 1.8 <0 1. OXIDE TREATED BY DUMP RESERVES AS OF 1969 IN TABLE. RPT. OF MARCOPPER(1975) INDICA 5MMT OF ORE @ 0.58 AVE. GRADE. IN AREAS OF MORE INTENSE ALTERATION, SOME SULFIDE DISSEMINATION OCCURS. CHALCOCITE OCCURS IN THE SUPERGENE ZONE, ALONG WITH QUANTITIES OF MALACHITE, AZURITE, CHRYSOCOLLA, NATIVE COPPER AND CUPRITE. MINOR AMOUNTS OF ANTLERITE, CHALCANTHITE, TENNORITE, AND CHALCOTRICHITE ALSO OCCUR IN THE SUPERGENE ZONE. THE CEMENT COPPER IS PRODUCED BY A SULFURIC ACID LEACHING PROCESS. IN 1978, A COMPLETE RE-EVALUATION OF THE LONG TERM MINE PLANNING WAS BEING MADE. THIS RE-EVALUATION WAS TAKING INTO ACCOUNT THE EXISTING LOW METAL PRICES AND THE FACT THAT THE ORE IN THE MT. TAPIAN DEPOSIT WOULD BE LESS PROFITABLE TO MINE AND PROCESS THAN THE ORE EXPECTED TO BE AVAILABLE FROM THE NEW SAN ANTONIO DEPOSIT AFTER 1981. THE RE-EVALUATION REPORT HAD NOT BEEN RELEASED AS OF THIS TIME.
