Chilean copper miner Antofagasta is evaluating building a new concentrator plant at its Centinela mine that would cost around $3 billion, the CEO of the company was quoted telling a local daily on Sunday.
Antofagasta’s copper production rose 3% to 725 300 t last year, allowing the company to weigh potential expansion projects and upgrades, Ivan Arriagada said, according to an interview published in La Tercera.
