Deposit UNDERGROUND PARALLEL LONGHOLE DRILLING INSTEAD OF FAN DRILLING HAS REDUCED THE COST OF DRILLING AND BLASTING BY ONE-THIRD. STARTING IN LATE 1976, MILL CAPACITY WILL BE INCREASED TO 3500 METRIC TONS/DAY. UNDERGROUND MINING METHODS ARE A COMBINATION OF SUBLEVEL OPEN STOPE AND SUBLEVEL CAVING WITH BELL-SHAPE ORE PASSES. BECAUSE OREBODIES ARE SPREAD APART, EXPLORATION AND DEVELOP- MENT COSTS ARE HIGH. THE AVAILABILITY OF AN ADEQUATE WATER SUPPLY COULD LIMIT EXPANSION PROJECTS. THE LOW TUNGSTEN RECOVERY IS DUE TO OVERGRINDING AND LACK OF JIGGING. THE CAPITALIZATION COST IS $60 MILLION. THE MINE HAS BEEN USED BY NATIVES, SPANIARDS, FRENCH, AMER- ICANS AND LATELY HAS BEEN NATIONALIZED BY THE MEXICAN GOVERNMENT. THE MINE IS THE SECOND LARGEST MEXICAN COPPER PRODUCER. THE PRESENT CONCENTRATOR WAS BUILT BETWEEN 1969-1971.
