Long-term view on the business
Against this backdrop, the longer-term investment case for Antofagasta hinges less on a single volatile session and more on the group’s ability to deliver stable copper volumes at competitive costs and to expand capacity in a disciplined way over the coming years.
The company has previously flagged a 2026 copper production target of 650,000-700,000 tonnes and plans to report second-quarter production figures on July 15, giving the market a fresh data point on how its Chilean operations are tracking against that medium-term ambition.
