Antofagasta 2022 copper production falls on drought, lower grades

(Reuters) - Chilean miner Antofagasta reported a 10.4% fall in 2022 copper output on Wednesday, as lower ore grades and a historic drought in Chile hurt production.

The London-listed group said it produced 646,200 tonnes of copper last year, at the lower end of its outlook of 640,000 tonnes-660,000 tonnes.
