Chilean miner Antofagasta announced plans to invest approximately US$900 million in a life-extension project for its Zaldívar copper mine, aiming to extend operations through 2051. The investment will include upgrades to mine infrastructure and sustaining capital required for continued operations. Zaldívar currently produces around 80,000–90,000 tonnes of copper annually. Extending the life of existing assets is becoming increasingly important as the industry faces challenges in developing new large-scale copper projects.
