A severe storm in Chile has disrupted copper production and resulted in at least 13 fatalities, prompting concerns about global supply and industry resilience amid changing climate conditions. The extreme weather, marked by heavy snowfall, historic rainfall, and mudslides across central and northern mining regions, led to a state of emergency declaration in certain areas.
Several major copper producers suspended or scaled back operations due to the storm’s impact. Canadian miner Lundin Mining halted activities at its Caserones copper-molybdenum mine in the Atacama region after heavy snow caused power outages. Similarly, Antofagasta reduced non-essential work at its Minera Los Pelambres site following drainage system overloads. Barrick Mining evacuated workers from a northern Chilean camp by helicopter amid difficult weather conditions. State-owned Codelco temporarily stopped some operations at mines including El Teniente and paused above-ground tasks at its Andina mine.
Executives from other leading mining companies such as Anglo American and BHP stated they were monitoring the evolving situation closely and maintained communication with Chilean authorities.
Chile is a critical supplier of copper, accounting for nearly a quarter of global production. The disruption caused by the storm has had immediate effects on the global copper market, which was already under pressure from forecasts predicting a 10-million-ton shortfall by 2040 due to factors including the depletion of aging mines. Copper is indispensable for electricity grids, renewable energy infrastructure, and the data centers that support artificial intelligence, with data centers alone requiring tens of thousands of tons of copper for wiring and cooling.
Market analysts warn that extreme weather events like this storm are likely to increase as climate change intensifies, posing growing risks to mining operations. While companies generally factor in some weather-related disruptions, the increasing frequency and severity of such events complicate accurate production and financial forecasting. These physical risks can affect production continuity, cash flows, insurance costs, and asset valuations.
The storm’s temporary shutdowns in a key mining nation like Chile underscore the vulnerability of global commodity markets to climate-driven supply shocks, contributing to increased price volatility and uncertainty in the copper sector.
