El Abra’s large sulfide would support a potential major mill project similar to the large-scale concentrator at Cerro Verde. Technical and economic studies continue to be evaluated to determine the optimal scope and timing for the sulfide project.
In parallel, as part of the permitting process for the potential expansion, Freeport-McMoRan is planning for a potential submission of an environmental impact statement during 2025. |

Summary:
The El Abra mine is a porphyry copper deposit that has sulfide and oxide mineralization. The predominant primary sulfide copper minerals are bornite and chalcopyrite. There is a minor amount of secondary sulfide mineralization as chalcocite. The oxide copper minerals are chrysocolla and pseudomalachite. There are lesser amounts of copper bearing clays and tenorite.
Summary:
El Abra is an open-pit copper mining complex that has been in operation since 1996 and is located 47 miles north of Calama in Chile’s El Loa province, Region II.
The available fleet consists of twenty-three 242-metric-ton haul trucks loaded by four electric shovels with buckets ranging in size from 29 to 41 cubic meters, which are capable of moving 217,000 metric tons of material per day.
The highest bench elevation is 4,225 meters above sea level and the ultimate pit bottom is expected to be 3,385 meters above sea level.
