MMG Ltd said on Thursday its copper output fell 20% year-on-year in the first quarter because of lower-than-planned production at the Las Bambas mine in Peru, where the miner has declared force majeure because of coronavirus-related curbs.
Las Bambas is among the world’s biggest copper mines and one of the major mining projects that has cut production, prompting Australia-based MMG to formally withdraw its full-year production guidance for the mine earlier this month.
