| Deposit | COMPAGNIE DE TIFNOUT TIRANIMINE. AT BOU AZZER, PLANS (AS OF 3/75) ARE FOR COBALT OUTPUT TO REACH 8,000 MTPY BY 1977. CONCENTRATOR 1972 FEED CAPACITY WAS 180,000 M.T.P.Y. |
| Deposit | DEPOSIT OCCURS IN AREAS OF PRECAMBRIAN ROCKS EXPOSED BY THE EROSION OF AN ANTCLINE OF YOUNGER ROCKS. THE TOTAL LENGTH OF OUTCROP, 35 MILES, 3 TO 9 MILES WIDE. THE OLDEST OF THE PRECAMBRIAN ROCKS ARE DIORITE AND A SERIES OF MICA SCHISTS AND GNEISS. YOUNGER THAN THESE IS A COMPLEX OF SERPENTINE AND OLIVINE BASALTS. THE ORE OCCURS IN VERTICAL EAST-WEST VEINS OR VEINLIKE MASSES AT OR NEAR THE CONTACT OF THE SERPENTINE AND THE DIORITE; MORE OF THE VEINS LIE IN THE SERPENTINE THAN IN THE DIORITE. VEINS HAVE MAX. WIDTH OF 5 FEET AND HAVE BEEN MINED TO 575 FEET IN DEPTH. OXIDATION HAS PRODUCED MINABLE AMOUNTS OF ERYTHRITE, ANNABERGITE, AND BLACK OXIDES. ORES ARE REPORTED TO CONTAIN 3 TO 300 GRAMS (0.1 TO 9.6 OUNCES) OF GOLD PER MET. TON, AND UP TO 50 GRAMS (1.6 OUNCES) OF SILVER PER MET. TON, (U.S. BUR. MINES, MATERIALS SURVEY: COBALT, REF. #3). BECAUSE CO IS THE PREDOMINANT MINERAL HERE, AND THERE IS A LACK OF ASSOCIATED METALS, ECONOMIC MINING REQUIRES A HIGER TENOR OF COBALT ORE THAN |
| Deposit | USUAL, AND FOR THESE REASONS, MINED ORES CONTAIN BETWEEN 1 AND 2 PERCENT COBALT. |
