Paipote Copper Smelter Delay Pushes Chile’s Processing Expansion to 2031

Enami copper

Paipote copper smelter development in northern Chile is facing a delay of more than two years, pushing the country’s major state-backed smelting expansion further into the next decade. Chile’s national mining company Enami now expects construction of the $1.7bn project to begin in October and finish in February 2031.

The revised schedule replaces the earlier plan to start construction in February and complete the project by November 2028. The new dates were included in documents submitted to Chile’s environmental evaluation service, Sea.

Paipote copper smelter modernization is strategically important because Chile remains one of the world’s largest copper producers but has limited domestic smelting and refining capacity compared with its concentrate output. The delay extends the period in which more Chilean copper concentrate will continue to depend on overseas processing.

The project is designed to more than double smelting capacity at the Paipote metallurgical complex to 850,000 t/yr of copper concentrates. It will also include an electrolytic refinery capable of producing 240,000 t/yr of copper cathodes.

Engineering Changes Add Cost and Push Back Construction

The delay follows completion of detailed engineering studies for the smelter. Enami said the proposed changes to the original project, which was approved in October 2025, will cost $65mn.

The changes include demolition of existing infrastructure at the metallurgical complex. Some structures must be removed because of age, while others interfere with the new construction plan.

This is a common risk in brownfield metallurgical projects. Existing plants often provide strategic location and infrastructure advantages, but they can also create cost, demolition and layout challenges when new technology is added.

Enami’s filing seeks confirmation from Sea that the proposed changes do not need to be submitted to Chile’s environmental impact evaluation system. The outcome will matter for timing because any additional environmental review could further extend the project schedule.

The Paipote copper smelter delay also reflects the complexity of modern smelting projects. New plants must meet tighter environmental standards, handle higher concentrate volumes and integrate refining capacity while controlling emissions and operating costs.

For Enami, the project is more than a capacity expansion. The company suspended the existing smelter in 2024 to stem financial losses and improve environmental performance. The modernization is therefore intended to rebuild processing capability on a more sustainable and competitive basis.

Chile’s Copper Value Chain Remains Exposed to Processing Bottlenecks

The delay has wider implications for Chile’s copper value chain. Chile produces large volumes of copper concentrate, but domestic processing capacity has not expanded in line with mine output.

A larger Paipote complex would strengthen local copper concentrate processing and increase domestic cathode production. It would also support small- and medium-sized copper producers, which rely on Enami to process, smelt and refine their material.

That role is important for Chile’s mining structure. Major copper producers often have access to export markets and long-term concentrate buyers. Smaller producers depend more heavily on national processing infrastructure to convert output into marketable products.

The project’s planned 850,000 t/yr concentrate capacity would give Enami a much stronger position in Chilean smelting. The 240,000 t/yr cathode refinery would also help capture more value inside the country rather than exporting concentrate for overseas treatment.

However, the new 2031 completion date means these benefits will arrive later than planned. In the meantime, Chile remains more exposed to global treatment charges, overseas smelter availability and concentrate export logistics.

The delay also comes as copper demand is increasingly tied to grids, electrification, renewable energy, electric vehicles and industrial investment. Chile’s ability to capture more value from copper will depend not only on mine output, but also on smelting, refining and downstream processing capacity.

For Enami, execution will be critical. The company must manage engineering changes, environmental requirements, demolition, construction and financing while restoring confidence in Paipote’s long-term role.

For Chile, the project remains strategically necessary despite the delay. A modern Paipote copper smelter could improve domestic processing resilience and support a more integrated national copper industry.

The Metalnomist Commentary

The Paipote delay shows that copper resource leadership does not automatically translate into processing strength. Chile needs modern smelting and refining capacity to capture more value from its copper base, but brownfield execution risk remains a serious bottleneck.

Chile Copper Mining Power Demand to Surge by 2034

Chile Copper

Rising Energy Needs Driven by Processing Shifts

Chile’s copper mining sector will face a sharp rise in power demand over the next decade. According to Cochilco, the state copper commission, the industry will require 32.5TWh of electricity in 2034, up 21% from 26.9TWh in 2024. In contrast, copper production will only expand by 5.6% to reach 5.7mn tonnes in the same period. The mismatch highlights the growing energy intensity of mining operations as ore grades decline.

A higher proportion of copper concentrate production and the increased use of desalinated seawater will drive demand. Cochilco estimates copper concentration will consume 18.7TWh in 2034, or 58% of the sector’s total power. Meanwhile, desalination and pumping water to arid northern mines will account for 5.4TWh, representing 17% of consumption.

Transition to Renewables Amid Rising Costs

Chile’s copper industry has already shifted much of its energy base toward renewables. By 2024, renewables represented 74% of the sector’s electricity use, with contracts steadily renegotiated away from fossil fuels. Cochilco forecasts this share will rise to 78% by 2026. Despite this progress, the overall growth in electricity demand underscores potential cost pressures and supply security challenges for producers.

Copper mining already accounts for one-third of Chile’s total power consumption, and the anticipated rise may stress the country’s grid capacity. Therefore, balancing sustainable energy supply with rising industrial needs will be central to maintaining Chile’s global copper dominance.

The Metalnomist Commentary

Chile’s copper sector is entering an era where energy demand grows faster than metal output. The transition to cleaner power sources is vital, but rising electricity costs and desalination needs will weigh on margins. Global buyers of copper should expect long-term pricing influenced not only by supply-demand balances but also by the escalating energy footprint of mining operations.

54% of the World's Copper Mines Face 'Drought Shock'

Anglo American Copper Mining

More than half of the world’s copper mines are exposed to 'drought risk'. Other major metal raw materials such as iron ore, lithium, and cobalt are also facing potential supply disruptions due to abnormal weather conditions.

Metalnomist stated in a report published on the 24th, “Climate anomalies caused by global warming will adversely affect the supply and demand of international raw materials.” The center cited data from the global consulting firm PricewaterhouseCoopers (PwC), predicting that by 2050, 54% of the world's copper mines and 74% of lithium and cobalt mines will experience reduced production due to drought. Water is essential for crushing mineral ores, separating impurities, and cleaning equipment. McKinsey highlighted that “copper, gold, iron ore, and zinc are particularly vulnerable to drought, as 30-50% of these mines are located in areas with insufficient water resources.”

Chile, which produced over 30% of the world's copper in 2020, is already suffering from severe drought. Chilean state-owned mining company Codelco produced only 1,325,000 tons of copper last year, the lowest in 25 years, due to water shortages and other impacts.

15 Years of Water Shortage in the World’s Largest Copper Reserve: "If Mining Halts, Prices Could Quadruple"

Metalnomist warned on the 24th, “Mining items heavily dependent on production from specific countries are at risk of global supply disruptions due to abnormal weather conditions.”

According to Metalnomist, 47% of the world's copper reserves are concentrated in three countries : Chile, Peru, and the Congo. 74% of iron ore is concentrated in China, Australia, and Brazil, while 80.8% of bauxite is concentrated in Guinea, China, and Brazil. Copper demand has recently surged due to the AI boom, raising concerns that any supply disruption could significantly impact the industry. Global infrastructure asset manager Macquarie Group predicts that the annual copper demand could increase by 2 million tons by 2030 due to the surge in AI data centers. Copper is crucial for the construction of both data centers and power grids.

Northern Antofagasta, Chile's largest copper and lithium deposit, is a prime example of a region unable to increase production due to water shortages. Reuters recently reported that local mining company Antofagasta PLC has been struggling to secure water supply as reservoirs have dried up due to a 15-year-long drought. In the first quarter of this year, Antofagasta PLC’s copper production decreased by 11% compared to the same period last year.

Limited water resources are also causing conflicts with local communities. Antofagasta PLC and Australian mining company BHP were sued by Chile’s National Defense Commission (CDE) in 2022 for environmental pollution. The CDE claimed that mining companies extracted water volumes exceeding regulations, causing severe damage to the local ecosystem and indigenous communities.

Seawater desalination plants are being considered as a solution to these issues. However, the high investment costs and long construction periods limit their ability to solve water problems immediately.

Due to structural constraints on copper supply, it is predicted that copper prices could skyrocket in the coming years. Goldman Sachs projected that the average copper price next year would be $15,000 per ton. Pierre Andurand, founder of hedge fund Andurand Capital, analyzed that the global copper supply shortage could drive prices up to $40,000 per ton by 2028. Copper traded at a record high of $10,857 per ton on the London Metal Exchange (LME) on the 21st of last month, before falling to $9,563 on the 21st of this month.

The increasing demand for electricity for cooling due to heatwaves is also expected to raise the demand for fossil fuels such as coal and natural gas. Metalnomist noted, “Europe is in a situation where it is inevitable to expand thermal power generation to meet the increasing electricity demand in summer,” and added, “In Asian countries such as Thailand, India, and Bangladesh, the demand for natural gas for power generation has increased.”

Argentina Glacier-Protection Reform Opens New Path for Copper Mining

Argentina glacier

Argentina glacier-protection reform has cleared the lower house, creating a major legal shift for the country’s copper industry. The reform allows provinces to decide which glaciers are functionally important to water resources and which areas may be opened to mining.

The approval followed senate backing on 27 February and passed the lower house late on 8 April by 137 votes to 111. President Javier Milei strongly supported the bill, making official promulgation likely.

Argentina glacier-protection reform could unlock copper resources located along the Andes, where many advanced projects overlap with glaciated areas. Supporters argue the change will reduce legal uncertainty and allow provinces to regulate their own natural resources.

Copper Projects Gain New Resource Expansion Potential

Argentina’s copper industry has remained underdeveloped despite a large resource base. The country holds 116mn t of copper resources, but exported only $4bn of the metal last year, far below Chile’s $50bn in copper sales.

The reform could materially change that outlook. Argentina’s 20 most advanced copper projects represent a combined $21.9bn in investment and may now be able to expand resource bases inside previously restricted glacier perimeters.

The mining secretary has forecast that Argentina could produce more than 1.5mn t/yr of copper by 2035, equal to 6.1% of global output. That target now looks more plausible if legal access improves and the government strengthens its large-investment incentive regime.

Argentina glacier-protection reform therefore comes at a critical moment for copper markets. Global demand from grids, electrification, renewable energy and industrial infrastructure needs large new projects, and Argentina is one of the few jurisdictions with major undeveloped copper potential.

Water Security Backlash Raises Political Risk

The reform has triggered strong opposition from environmental groups, lawmakers and parts of the public. Critics argue that easing glacier protections could threaten Argentina’s water security, especially because glacier meltwater supports rivers and agricultural systems.

Greenpeace activists protested outside the lower house in Buenos Aires and warned that the reform could open the way to damaging much of Argentina’s glacial environment. Opponents say drinking water reserves should not be exposed to mining risk.

Supporters of the reform insist that provinces will not permit mining on glaciers that are vital to water resources. However, implementation will depend on how provinces define “functional” and “non-functional” glaciers in practice.

This creates a new layer of project risk. Copper developers may gain legal opportunity, but they will still need political acceptance, environmental credibility and clear provincial rules to move projects into construction.

The Metalnomist Commentary

Argentina glacier-protection reform could become one of the most important copper policy changes in Latin America. The opportunity is large, but the social licence risk is equally serious if water security concerns are not managed with transparency and science.

Ceibo Delivers First Copper Cathode Using Sulphide Leaching Technology in Chile

Ceibo

Innovative Technology Targets Low-Grade Copper Ores

Ceibo, a Chilean copper extraction technology firm backed by Australia’s BHP, has produced its first copper cathodes from a sulphide-leaching operation at Minera San Geronimo (CMSG) in northern Chile. The demonstration plant, constructed earlier this year, employs Ceibo’s proprietary technology to increase copper recovery from low-grade ores without major infrastructure upgrades. This innovation comes as the mining sector seeks efficient, lower-impact solutions to sustain long-term production.

Addressing Global Copper Supply Challenges

Ceibo’s technology has already achieved a 75pc recovery rate in under a year, showing strong potential for commercial scalability. The Paris-based IEA forecasts copper demand to grow by 30pc by 2040, with a looming 30pc primary supply deficit expected by 2035. As a result, technologies like sulphide leaching could play a critical role in bridging the supply gap while reducing environmental impacts. Several global firms are pursuing similar methods to boost extraction efficiency and meet accelerating demand from clean energy, EVs, and infrastructure projects.

The Metalnomist Commentary

Ceibo’s milestone is a timely development for Chile’s copper sector, particularly as high-grade reserves decline. If scaled successfully, this technology could help secure Chile’s position as a leading copper supplier while mitigating environmental concerns and meeting the mining industry’s sustainability goals.

Climate risk to copper threatens chip supply

Pricewater house Coopers

Risk concentration and timelines

Climate risk to copper threatens chip supply by 2035, PwC warns. Climate risk to copper could disrupt one-third of global semiconductors. Climate risk to copper stems from drought and extreme weather at key mines. By 2035, 32% of chip production will rely on at-risk copper. By 2050, exposure could rise to 58% without adaptation.

Chile’s exposure underscores the systemic risk to copper supply. Today, one quarter of Chilean copper faces drought disruption. Within a decade, that share could reach 75% of output. By 2050, the risk could span 90–100% of production. Therefore, global chipmakers inherit Chile’s water stress through copper inputs.

Most copper-supplying countries will face drought risk by 2035. The risk set includes the majority of 17 key producers. As a result, single-region sourcing will amplify volatility. Hence, procurement planning must assume multi-year water shocks.

Mitigation strategies and industry responses

Miners are deploying desalination and water recycling to reduce risk. Several Chilean operations already pipe desalinated water to site. However, these projects require large capital and reliable power. Therefore, build-out speed may lag rising climate pressures.

Downstream buyers must diversify copper inputs and forms. Smelter contracts should include climate and water performance clauses. Meanwhile, scrap utilization can buffer refined copper tightness. As a result, OEMs can temper risk to chip supply chains.

Technology choices can also ease the risk to copper exposure. Closed-loop water systems lower fresh-water dependence at plants. Dry-stack tailings reduce evaporation and seepage losses. Therefore, integrated ESG and engineering plans become commercial necessities.

The Metalnomist Commentary

Climate risk is now a fundamental copper cost and availability driver. The winners will pre-finance water resilience and lock diversified supply. Expect copper contract structures to price water risk more explicitly.

Antofagasta Maintains Copper Production Guidance for 2025 Amid Incremental Increase at Centinela Mine

Antofagasta

London-listed mining company Antofagasta has kept its copper production guidance steady for 2025, projecting flat output compared to 2024. Despite the stable forecast, the company expects an incremental increase in copper concentrate output at its Centinela mine in Chile.

2024 and 2025 Copper Production Outlook

Antofagasta confirmed that it is on track to meet its copper production guidance for 2024, expecting to finish the year at the lower end of its previously set range of 670,000-710,000 metric tonnes (t) of copper. For 2025, the company projects production to range between 660,000-700,000t, maintaining a stable output despite the minor increase at Centinela. The increase is attributed to a boost in concentrate production at the mine, although specific details were not provided.

Third Quarter Performance

In the third quarter, Antofagasta reported a 3% year-on-year increase in copper production, rising to 179,000t from 173,600t in the same period last year. The increase was largely driven by a partial destocking of inventories at its Los Pelambres mine and improvements in copper grades and recoveries at the Centinela mine. These efforts contributed to a 15.3% quarter-on-quarter rise in copper output, reflecting the company’s ongoing optimization at its operations.

Copper Sales and Molybdenum Production

Alongside the increase in copper output, Antofagasta's copper sales grew by nearly 11.4% year-on-year to reach 176,500t in Q3, marking a 9.3% increase compared to the previous quarter. However, the company faced a decline in molybdenum production, which fell 15% year-on-year to 2,700t. Despite this, it showed an 8% improvement compared to Q2 2024.

Chile's Role in Global Copper Supply

As the world’s largest copper-producing nation, Chile plays a central role in Antofagasta's operations. The company operates four mines in the country, including the Los Pelambres and Centinela mines, which are key contributors to global copper supply. Despite challenges in the mining sector, Antofagasta continues to focus on efficiency improvements and maintaining its production levels.

Antofagasta’s stable production guidance for 2025 comes as the global copper market braces for ongoing fluctuations in demand, particularly from industries like electric vehicles (EVs) and renewable energy. The company's consistent output is indicative of its robust position in the global copper market, with its operations in Chile continuing to be a significant driver for the industry.

Japan’s Nittetsu Joins Canadian Firm to Develop Chilean Copper Mine, Eyes Increased Output by 2033

Nittetsu

Japanese metal producer Nittetsu Mining has entered into a 50:50 joint venture with Vancouver-based Camino Minerals to advance copper production through the Puquios Copper Project in Chile's Coquimbo region, Nittetsu announced on October 8. This initiative aligns with Nittetsu’s mid-term goal of producing 50,000 tonnes of copper annually by 2033, a strategic objective in Japan's effort to bolster base metal self-sufficiency amid rising global demand for copper.

Investment and Production Outlook Remain Under Wraps

Although specific investment figures and expected production volumes of crude ore and copper concentrate have yet to be disclosed, the Puquios project is estimated to yield about 15,000 tonnes of copper equivalent annually. Commercial operations are projected to begin after environmental approvals, a process that could take several years. Nittetsu Mining's general manager, Shinichiro Mita, emphasized that this partnership leverages the company's technical prowess and longstanding expertise in copper production, underscoring Nittetsu's commitment to expanding its role in the global copper market.

The Puquios development is Nittetsu’s latest move in Chile. The firm has also been working on the Arqueros copper project, backed by the Japan Bank for International Cooperation (Jbic). Production at Arqueros is anticipated to reach 15,000 tonnes per year between April 2026 and March 2027, mirroring Puquios’ forecasted output.

Government’s Strategic Drive for Self-Sufficiency

Japan’s government has been actively encouraging domestic firms to secure copper sources abroad to address its base metal deficit. The country’s energy strategy, updated in 2021, targets a base metal self-sufficiency rate of 80 percent by 2030, up from 50 percent in 2018. Despite these ambitions, Japan’s Ministry of Economy, Trade, and Industry (Meti) recently acknowledged that the target is not on track, though it withheld details on current self-sufficiency rates.

Nittetsu expects copper prices to hold a bullish trend in the long term due to sustained demand for the metal, particularly for decarbonization and electrification initiatives. However, the company has cautioned that short-term copper price volatility may increase due to fluctuating global market conditions.

Chile's Enami Puts 450,000t of Copper Stock on Sale

Chile's Enami

Chilean state-owned mining company Enami has announced plans to sell 450,000 metric tonnes of copper as part of efforts to regain financial stability. The copper, which has been oxidized and processed at the Barriles de Tocopilla plant, is valued at around $60 million. This stockpile is notable not only for its large volume but also for the fact that it has already been collected and crushed, making it more accessible to buyers.

Financial Recovery Strategy

Enami's decision to sell its copper stock follows a challenging financial period. The company posted a loss of $200 million in 2023, prompting a need for immediate action to address its financial standing. By liquidating this significant batch of copper, Enami aims to stabilize its finances and continue supporting small-scale mining, a sector that remains central to its operations.

"Our goal is to achieve financial sustainability, a necessary condition to continue playing a key role towards small-scale mining, which is our main asset," said Javiera Estrada, Enami's executive vice-president.

Enami's copper sale is expected to generate significant interest, given the large volume and the current demand for copper in global markets. This move marks a critical step for the company as it seeks to reposition itself financially and sustain its influence in the mining industry.

Surge in Copper Production: Codelco and BHP Lead the Way

Codelco

A Closer Look at November's Copper Production Increases

Chile's premier state-run enterprise, Codelco, along with the Australian mining giant BHP's Escondida mine, have reported significant increases in their copper production for November. This development could signal a robust period for the metal's market moving forward.

Significant Gains Amidst Global Challenges

In a detailed report from the Chilean copper commission Cochilco, it is noted that Codelco's production for November reached 133,600 tons. This figure represents a remarkable 17% increase compared to the same period in 2023, marking the highest output observed last year. Despite facing production challenges earlier in the year, Codelco has evidently managed a vigorous recovery in the latter half.

On the other hand, BHP's Escondida mine, the largest copper mine in the world, produced 108,200 tons of copper in November alone, up by 28% from the previous year. This substantial growth underscores Escondida's critical role in the global copper market.

Variance Among Competitors

While Codelco and BHP have enjoyed production boosts, not all industry players saw the same success. The Collahuasi mine, which is a joint venture between Anglo American, Glencore, and Japan's Collahuasi Resources, experienced a downturn. The mine's output declined by nearly 24% year-on-year, totaling only 36,700 tons in November.

Despite these mixed results, the overall copper production in Chile from January to November stood at approximately 4.94 million tons, marking a 3.9% increase over the previous year. This growth is largely attributed to the strong performances of both Escondida and Codelco during the latter half of the year.

Chile Rejects Dominga Iron-Copper Project for Third Time

Andes Iron

Chile's government has once again denied environmental approval for Andes Iron's proposed Dominga iron and copper mine, citing significant environmental concerns. This marks the third time the project has been rejected, underscoring the challenges of balancing economic development with environmental protection in Chile's crucial mining sector.

Repeated Rejection and Environmental Concerns

A ministerial committee, led by the Ministry of the Environment (MoE), unanimously voted against the $2.5 billion project. The decision stems from concerns about the project's potential impact on biodiversity and the adequacy of Andes Iron's contingency and emergency plans for at-risk species. The committee's statement highlighted these environmental risks as the primary reasons for the denial.  This follows previous rejections in 2017 and 2023, with Andes Iron's appeals ultimately leading to a Supreme Court review in 2022, which seemingly did not sway the final decision.

Project Details and Industry Context

The Dominga project, an open-pit mine proposed for the Coquimbo region, aimed to produce 12 million tonnes per year of iron concentrate and 150,000 tonnes per year of copper concentrate as a byproduct over a 27-year lifespan.  Its rejection comes as Chile anticipates a substantial increase in copper production capacity—2.23 million tonnes per year between 2024 and 2033—driven by approximately $83.2 billion in mining investments across 51 projects.  This context emphasizes the tension between Chile's drive for mining development and growing environmental scrutiny.

Andes Iron's Response

Andes Iron has repeatedly asserted that the project complies with environmental regulations and has accused the MoE of bias.  The company's future course of action regarding the Dominga project remains uncertain following this latest setback.

Chile Rio Tinto Lithium Deposit Partnership Secures Largest Undeveloped Resource

Chile Rio Tinto

Chile Rio Tinto lithium deposit partnership emerged as Chile's national mining company Enami selected the Anglo-Australian miner to explore and develop the Altoandinos project, the country's largest undeveloped lithium deposit. The Chile Rio Tinto lithium deposit agreement establishes a public-private concession with Rio Tinto holding 51% ownership while Enami retains 49%, representing a combined $3 billion investment where Rio Tinto contributes $425 million for access to over 15 million tonnes of lithium carbonate equivalent resources.

Competitive Selection Process Validates Rio Tinto's Technology Leadership

Chile Rio Tinto lithium deposit selection followed Enami's unanimous board decision choosing Rio Tinto from a competitive pool including China's BYD, France's Eramet, and South Korea's Posco. Rio Tinto's proprietary direct lithium extraction (DLE) technology provided the decisive advantage, offering faster and more environmentally friendly operations compared to traditional evaporation methods. The DLE approach eliminates brine evaporation requirements while accelerating production timelines and reducing environmental impact.

Meanwhile, Rio Tinto's Rincon plant in Argentina serves as a demonstration and pilot facility for Chilean operations since both brine deposits share similar chemical compositions. This existing operational experience provides technical validation and reduces development risks for the Altoandinos project. Rio Tinto will assume complete operational responsibility while financing the project through financial operation and contributing to pre-feasibility study expenses.

Massive Resource Scale Supports 75,000 Tonne Annual Production

However, the Altoandinos salt flat contains substantial lithium resources exceeding 15 million tonnes of lithium carbonate equivalent with production capacity reaching 75,000 tonnes annually according to Enami projections. This production scale positions the project among global lithium industry leaders while supporting Chile's strategic objectives for lithium sector development. The resource magnitude justifies the $3 billion investment commitment from both partnership participants.

Therefore, the project timeline remains under development with no specific operational start date announced pending pre-feasibility study completion and regulatory approvals. The comprehensive development approach ensures technical optimization while addressing environmental and social considerations essential for sustainable lithium extraction. Rio Tinto's operational expertise combined with Enami's local knowledge creates optimal conditions for successful project implementation.

Strategic Expansion Reinforces Chile Lithium Market Leadership

Furthermore, the Altoandinos partnership follows Rio Tinto's recent selection by Chilean copper giant Codelco for the Maricunga salt flat exploration, representing Chile's second-largest undeveloped lithium deposit. This dual partnership positioning demonstrates Rio Tinto's strategic commitment to Chilean lithium development while reinforcing Chile's global lithium market leadership. The concurrent projects create synergies for technology deployment and operational efficiency.

As a result, Chile strengthens its position as the world's premier lithium jurisdiction through strategic partnerships with established international miners possessing advanced extraction technologies. The public-private partnership model enables state participation in resource development while leveraging private sector expertise and capital. This approach maximizes economic benefits while maintaining national control over strategic mineral resources essential for global energy transition.

The Metalnomist Commentary

Chile's selection of Rio Tinto for both the Altoandinos and Maricunga lithium projects demonstrates sophisticated resource development strategy that prioritizes advanced extraction technology and environmental sustainability over purely financial considerations. The emphasis on direct lithium extraction capabilities reflects Chile's commitment to maintaining global lithium leadership through technological innovation, particularly important as competition intensifies from emerging producers in Argentina, Australia, and other jurisdictions seeking market share.

SQM Defends Lithium Partnership with Codelco Amid Criticism

SQM

SQM, one of the world’s largest lithium producers, has defended its proposed joint venture with Chile’s state-run copper mining company Codelco, stating that the deal will benefit all stakeholders involved. SQM’s general manager, Ricardo Ramos, addressed the Chilean Senate’s mining and energy committee, emphasizing that the partnership would promote economic and operational continuity for the Atacama lithium operations well beyond 2030.

Ensuring Operational Continuity and Avoiding Disruptions

The public-private joint venture, aimed at running SQM’s lithium operations in the Atacama salt flat, is expected to prevent potential disruptions that might occur if a new private entity were to take over SQM’s operations when its current contract expires in 2030. Ramos argued that allowing Codelco, a government-backed company, to partner with SQM would ensure that both the country and its communities benefit from stable and increased lithium production.

Critics of the deal have expressed concern that a public tender process could have secured more favorable terms for Chile, but SQM and Codelco maintain that the JV agreement, set to finalize in 2025, is the most effective way forward. Under the deal, Codelco will have rights to 33,500 metric tonnes per year of lithium carbonate equivalent (LCE) and will take control of the operation by 2031, with SQM retaining a minority stake.

SQM is also seeking regulatory approval to expand its production capacity to an additional 300,000 tonnes of LCE between 2025 and 2030, supplementing its current output, which represents 20% of global demand. However, the deal faces a legal challenge from Tianqi Lithium, a shareholder in SQM, over the transaction’s approval process.

Chile’s strategy with this joint venture aligns with its broader goal of increasing lithium production while establishing a stronger state presence in the industry.

New Medical Device Demand to Disrupt Rhenium Market

Spinal Implants

MoRe Alloys Spark Medical Breakthroughs

New demand for rhenium in medical applications is poised to reshape the global rhenium market. Historically driven by superalloys used in aerospace engines, rhenium is now being adopted for advanced medical devices. Molybdenum-rhenium (MoRe) alloys, particularly Mo50 Re, have recently gained US FDA approval for use in spinal implants and cardiovascular stents.

Several devices using MoRe alloys have entered the US market in the past 18 months, signaling a structural demand shift. According to the MMTA conference in Lisbon, these devices could soon rival aerospace in total rhenium consumption. MiRus, a leader in MoRe medical technology, has already received multiple FDA clearances for spine and structural heart treatments.

Global Supply Faces New Pressures

China, now the top importer of rhenium from Chile’s Molymet, has ramped up consumption for its growing aerospace sector. In 2023, China imported 26 tonnes of Chilean rhenium, a dramatic increase from just 2 tonnes in 2018. Traditionally, the US aerospace industry dominated rhenium imports, accounting for 75% of global demand.

However, experts warned that aerospace users must now compete with the fast-growing medical sector. Medical-grade MoRe alloys offer superior strength, fatigue resistance, and biocompatibility. Unlike nickel, cobalt, or chromium implants, MoRe devices do not trigger allergic reactions and have shown zero breakage in trials.

Long-Term Outlook Points to Tight Supply

Rhenium's unique properties are driving innovation in smaller, fatigue-resistant implants. Titan International noted MoRe-based implants offer greater durability and precision in surgeries. As global populations age, demand for reliable orthopedic and cardiovascular devices is expected to surge.

Yet supply growth remains constrained. With no major new rhenium mines and declining grades in copper-molybdenum ores, primary output is projected to stay flat. Speakers forecast that elevated prices could eventually stimulate recycling, but short-term supply pressure remains a key concern.

The Metalnomist Commentary

Rhenium’s shift from jet turbines to spinal implants underscores how material science breakthroughs can reshape strategic metals markets. With Chinese aerospace demand rising and MoRe alloys entering the medical mainstream, the global rhenium balance may tighten further. This evolution highlights the urgent need for recycling solutions and diversified sourcing strategies in the decade ahead.
