Chile’s Sierra Gorda mine and BHP’s Spence operation have signed a memorandum of understanding (MoU) to evaluate collaboration opportunities in supply chains, operating processes and infrastructure aimed at reducing costs, improving efficiency and enhancing long-term competitiveness. Both operations are facing declining ore grades and increasing operational complexity. At the same time, BHP is advancing a concentrator expansion project at Spence, while Sierra Gorda is progressing an SX-EW project expected to produce approximately 30,000 tonnes of copper cathodes annually.

According to the China Earthquake Networks Center, at 5:52 AM Beijing time on May 26, 2026 (5:52 PM local time on May 25), a magnitude 6.9 earthquake struck the Antofagasta Region in northern Chile, with a focal depth of approximately 114 kilometers. The U.S. Geological Survey (USGS) measured the focal depth at approximately 109 kilometers. Within a 200-kilometer radius of the epicenter, 21 earthquakes of magnitude 3 or above have occurred in the past five years, the largest being a magnitude 7.3 earthquake on July 19, 2024. The Antofagasta Region is Chile's core mining area and a globally significant copper mine concentration zone. Following the earthquake, the global copper market quickly turned its attention to local mine production and transportation conditions. Codelco stated that due to low visibility in mine pits and localized power outages, the company had suspended some production activities and initiated safety inspection procedures. According to SMM, the affected mines under Codelco have now resumed normal production. Global mining giant BHP and Antofagasta PLC indicated that their operations were generally unaffected, but they had temporarily halted some operations in accordance with emergency protocols to conduct safety assessments of facilities. Chile's National Disaster Prevention and Response Service (SENAPRED) reported that the earthquake triggered landslides in some production areas, and Calama experienced power outages and localized water supply disruptions. However, no casualties or major infrastructure damage had been reported, and ports and major transportation facilities were currently operating normally. Although this earthquake was of relatively high magnitude with a deep focal point, given Chile's relatively mature seismic-resistant mining infrastructure system, the actual impact of this event on the global copper supply chain was temporarily limited, manifesting more as short-term sentiment disturbance. However, as the world's largest copper-producing country, Chile holds a pivotal position in the global copper supply chain. Data from China's General Administration of Customs showed that from January to April 2026, China imported a total of 9.9151 million mt in physical content of copper concentrates, of which 3.0526 million mt in physical content were imported from Chile, accounting for approximately 30.79%. Chile remained China's largest source of copper concentrates imports. Against the backdrop of already tight global copper concentrates supply and persistently low treatment charges (TCs), any production disruption from Chile's core mining areas could trigger copper price fluctuations. If subsequent situations arise such as prolonged mine shutdowns, hindered port transportation, or slow power restoration, this could further push up international copper prices and the performance of related non-ferrous metals sectors. As of now, major miners in Chile have not disclosed any significant facility damage or long-term shutdown information.

BHP Group said on Tuesday, May 26, that the earthquake in Chile's Antofagasta region had no impact on the company's operations. According to Xinhua News Agency, citing the National Seismological Center of the University of Chile, a magnitude 6.9 earthquake struck the Antofagasta region in northern Chile on the 25th. No casualties or property damage have been reported so far. The earthquake occurred at 17:52 local time on the 25th (5:52 Beijing time on the 26th), with the epicenter located 20 kilometers northeast of Calama City in the Antofagasta region, at a depth of 114 kilometers.

[SMM Analysis] Can Indonesia import sulfuric acid as a substitute after the sulfur restriction?

Copper prices moved closer to record highs on May 8, driving strong gains in shares of BHP and Rio Tinto. Investors are increasingly betting that AI infrastructure, power grid upgrades, and clean energy investment will create long-term structural demand for copper. Analysts in Australia said discussions around a new commodity supercycle are intensifying as capital flows back into mining stocks.

Rio Tinto shares jumped as investors bet on rising copper demand from AI infrastructure and electrification. The company is also advancing the Resolution Copper project with BHP , strengthening its long-term copper strategy.

Argentina expects copper and lithium exports to surge over the next decade, driven by President Milei’s mining investment incentives. The government said major companies including BHP and Rio Tinto are expanding investment plans as the country positions itself within a future “copper triangle.”
