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.

According to the China Earthquake Networks Center, a magnitude 6.9 earthquake struck the Antofagasta Region in northern Chile at 17:52 local time on May 25 (05:52 Beijing time on May 26, 2026), with a focal depth of approximately 114 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 of which was a magnitude 7.3 earthquake on July 19, 2024. According to data from the General Administration of Customs, Chile is the largest source country for China's copper concentrate imports. 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%.

Antofagasta Plc is taking an early look at opportunities in Argentina as sweeping policy changes revive interest in one of the world’s most promising new copper frontiers, chief executive officer Iván Arriagada said in an interview.The Chilean miner would consider entering through standalone exploration or a partnership with existing projects, such as Glencore Plc’s El Pachón, which is just across the border from Antofagasta’s flagship mine in Chile, Arriagada said Monday. The interest is at an early stage, without any specific targets, he said.

[Australia’s Atlantic Lithium Secured Ghanaian Parliamentary Approval to Develop the Ewoyaa Project] Australia’s Atlantic Lithium secured approval from Ghana’s parliament to develop the Ewoyaa project—the country’s first lithium mine—under revised royalty terms linked to market prices. The approved 15-year lease introduced a sliding royalty scale for spodumene concentrates, set at 5% when prices are below $1,500/mt and 12% when they exceed $3,200/mt, replacing Ghana’s previous fixed 10% rate. The new structure followed broader reforms to the lithium and gold royalty framework passed earlier this month, paving the way for the project. The approval formally backed plans for the mine and processing plant, enabling Atlantic Lithium to advance financing discussions and move toward a final investment decision. The project had stalled after lithium prices pulled back from their peak at the end of 2022, prompting the company to push for more flexible fiscal terms. According to the company, Ewoyaa is expected to produce 3.6 million mt of lithium ore concentrates over 12 years, making it Africa’s third-largest lithium project under development. Atlantic Lithium said the project is the only lithium mine development project on the African continent aligned with the US, standing in sharp contrast to other projects backed by Chinese investment. Half of Ewoyaa’s production has been committed to Elevra Lithium, the merged entity of Piedmont Lithium and Sayona Mining, which had previously signed offtake agreements with Tesla and LG Chem. Company executives said details of the work completed in H2 2025 to improve project economics amid continued lithium price fluctuations and help define the next stage of development will be announced soon.

On June 12th, Bloomberg reported that Teck Resources and Sumitomo Metal Mining are locked in a dispute over treatment and refining charges (TC/RCs) in a major copper concentrate supply agreement. The disagreement, centered on shipments from Teck’s Quebrada Blanca and Highland Valley mines, has prompted the appointment of lawyers to select an industry expert as an independent referee. The clash highlights cracks in the traditional benchmark pricing system, after Antofagasta’s 2025 deal with Chinese smelters set TC/RCs at $21.25/2.125 cents, far below historical norms. Some Japanese buyers, including Sumitomo, have resisted adopting this benchmark amid sharply falling spot TC/RCs, which have recently turned negative. The situation underscores growing tension between well-funded Chinese smelters and financially pressured Western peers, with some smelters in the Philippines and Namibia already suspending operations.

[SMM Analysis: When It Rains, It Pours - Global Copper Concentrates Supply-Demand Balance After the Earthquake at KK Mine] At the end of May, Chinese smelters and Antofagasta commenced mid-year negotiations. In the first round of negotiations this year, miners had already offered a midpoint price of -US$15 to the smelters. This figure was significantly lower than the US$0/dmt that had circulated in the market in late April. According to SMM, many raw material procurement teams from leading smelters in the CSPT group indicated that the negotiations were fraught with difficulties, and it was exceptionally challenging to secure a favorable figure.

The pricing coefficient for 20% grade domestic trade ore was 93%-95%. Trading activity in the copper concentrate spot market was sluggish during the week. A trader offered 10,000 mt of clean ore from Peru to a smelter at a price in the mid-to-high -$40s/dmt, with a loading period in July and a QP of M+1/5. A smelter had previously purchased 20,000 mt of Caserones and Centinela copper concentrates from a large trader under an index-linked settlement model, with a loading period in July and a QP of M+1/5. During the week, a trader offered 10,000 mt of bundled clean ore to a smelter at a high -$40s/dmt price, with a loading period in July. The gold payable was fully priced after a deduction of 0.3 for gold content below 1 gram. According to market rumors, a large trader offered copper concentrates to two leading domestic smelters, with a total volume of 300,000 mt of ore (long-term contract + spot cargo) at a price in the mid-to-high -$40s/dmt, with a loading period in H2. According to SMM, most Chinese smelters participating in long-term contract negotiations have not yet received a second-round long-term contract offer from Antofagasta. However, one smelter has already responded with a positive single-digit high offer. Japanese smelters have also not initiated a second-round long-term contract offer. They are adhering to the pricing stance since CESCO at the end of last year, insisting on a long-term contract price of $20/30, otherwise, their production and operation will face losses. Ivanhoe Mines announced its latest 2025 production guidance for copper from the Kamoa-Kakula mine, which is 370,000-420,000 mt in metal content, a decrease of 28% from the 520,000-580,000 mt in metal content guidance released at the beginning of the year, mainly due to the earthquake that previously hit the Kakula copper mine. Sinomine Resource Group announced that due to the rapid expansion of global copper smelting capacity, leading to a shortage of copper concentrate supply, its Tsumeb copper smelter in Namibia has temporarily suspended copper smelting operations.
