Lundin Mining has maintained its full-year 2026 copper production guidance despite a severe winter storm knocking out grid power at its Caserones mine in Chile.
The outage, caused by damage to two transmission towers in the Atacama Region, forced a temporary halt in operations but did not prompt the company to revise its annual outlook.
This development adds nuance to Chile’s broader strategic push to attract approximately US$100 billion in mining investment over the next decade.
The decision to hold the line on guidance comes as broader supply-side risks loom over the global copper market.
A powerful winter storm is currently battering Chile’s northern mining regions, threatening operations in the country that supplies nearly a quarter of the world’s copper.
While Lundin’s specific impact appears contained, the event underscores the vulnerability of critical mineral supply chains to extreme weather events in key producing jurisdictions.
