Actualmente la faena Cerro Verde mueve cerca de 700.000 tpd de material: 360.000 tpd dirigidas a las concentradoras, 40.000 tpd de óxidos para lixiviación y 300.000 tpd de estéril. Esto aumentará a 800.000 tpd en 2018 cuando se amplíen los rajos Cerro Verde y Santa Rosa, y se empiece a minar la zona que los separa uniéndolos en uno solo.
