Chile’s copper output down in 2019 on declining grades

Copper production in 2019 in Chile, the world’s no. 1 producer of the metal, dropped by 44,000 tonnes compared to 2018, amid a perfect storm of falling ore grades at the largest deposits, water scarcity and operational issues. Cochilco, the country’s copper commission, said Codelco, the state-owned giant, was the miner most affected by ageing mines as its production declined by 5.6% in 2019 by about 100,000 tonnes.
