Freeport to finish Grasberg open pit mining by year end
Diversified miner Freeport-McMoRan is expected to complete mining in the Grasberg open pit by the end of the year, while also ramping up production at its Deep Mine Level Zone (DMLZ) underground mine and Grasberg Block Cave (GBC) mine in Indonesia.
Arizona-based Freeport said copper ore extraction from the DMLZ underground mine, which is located east of the Grasberg ore body, averaged 9,900 t/d in the third quarter, up from 7,800 t/d in the second quarter. Production is expected to ramp up to 11,000 t/d by the end of the year and 28,000 t/d in 2020 before reaching full production of 80,000 t/d in 2022.
Freeport said it exceeded expectations at the DMLZ underground mine and the GBC underground mine in the third quarter. At the GBC underground mine, Freeport extracted 10,600 t/d of ore in the third quarter, up from 7,400 t/d of ore in the second quarter. Freeport expects to ramp up to 16,000 t/d by the end of the year, which is 1,000 t/d higher than the estimates given in the second quarter earnings. Production rates are expected to increase to 130,000 t/d over the next five years.
Freeport is mining the final stages of the Grasberg open pit as it transitions to the underground mines.
