Chile’s Codelco, the world’s top copper producer, boosted output by 7.5% in September to 145 300 t, Chilean copper commission Cochilco said on Thursday, though its total production for the year continued to lag.
The state miner saw its production in the first nine months of 2019 drop 6.7% versus the previous year, reaching 1.2 million tonnes by September, Cochilco data showed.
