Which major copper mines in central Chile suspended or curtailed operations due to the winter storm, and what specific activities were affected?

Codelco suspended surface activities at its Andina mine northeast of Santiago and halted ore shipments from the open pit at El Teniente due to snow; Anglo American is monitoring conditions and adjusting operations as needed at its Los Bronces mine; Antofagasta reduced non-essential activities at its flagship Los Pelambres mine. The maritime authority reported restricted vessel movements at ports in central Chile, while northern mines—including those operated by BHP Group—remained unaffected and continued normal operations.

Why is this weather-related disruption in central Chile significant for global copper markets?

The disruption is significant because Chile accounts for a quarter of the world’s mined copper, and the storm occurred amid tightening global copper supplies—a metal critical for air conditioners, data centers, and other essential infrastructure. Although the largest northern mines remained operational, the extent of impact depends on how far north the storm reaches and how long it lasts, and Chile’s copper output has already been constrained in recent years by operational setbacks and declining ore grades.
