Los Bronces Andina Joint Mine Plan Targets Major Chile Copper Growth

Codelco

Los Bronces Andina joint mine plan has cleared another major milestone after Anglo American and Chilean state-owned Codelco completed their agreement to coordinate development of the neighbouring copper operations.

Los Bronces Andina joint mine plan is expected to unlock an additional 2.7mn t of copper over 21 years from 2030. The companies expect the arrangement to lift combined production by around 120,000 t/yr.

Los Bronces Andina joint mine plan is strategically significant because it creates additional copper supply without relying entirely on a new greenfield mine. Instead, Anglo and Codelco will optimise adjacent resources, infrastructure and mine planning across two established operations.

The agreement is also expected to generate at least $5bn in cost savings. Its implementation remains subject to environmental permitting and other customary conditions, with the joint plan expected to begin around 2030.

Adjacent Mines Create Lower-Cost Copper Growth

Los Bronces and Andina sit next to each other in one of Chile’s most important copper districts. Coordinating development allows the companies to optimise resources that would be less efficiently exploited under separate mine plans.

This type of brownfield growth is increasingly valuable for the copper market. New mines face long permitting periods, rising capital costs and infrastructure challenges, while existing districts can often add production faster through operational integration.

The projected additional 2.7mn t of copper is therefore meaningful for long-term global supply. Copper demand continues to rise across power grids, renewable energy, electric vehicles, data centres and industrial electrification.

Anglo’s Los Bronces operation has already shown improving performance. First-quarter output rose by 12% to 48,500t after the restart of its second processing plant.

The joint plan could build on that recovery by improving access to ore and creating a more efficient long-term mining configuration across the wider district.

Chile Looks to Joint Development to Lift National Output

The agreement supports Chile’s goal of raising national copper production to 6mn t/yr by 2030. Maintaining that position will require new projects, mine-life extensions and better productivity from existing assets.

Anglo and Codelco expect the joint plan to save at least $5bn while maintaining existing environmental and sustainability commitments. That combination of higher output and lower unit development cost is increasingly important as copper projects become more expensive.

The agreement also allows both companies to continue pursuing standalone projects. For Anglo American, that includes its planned merger with Teck to create Anglo Teck Group, with a portfolio focused on copper, iron ore and zinc.

Environmental approval remains the key outstanding condition. That means the projected additional copper will not reach the market immediately, but the project strengthens Chile’s long-term supply pipeline.

For the global copper industry, the deal highlights an important growth model. Future supply may increasingly come from cooperation between neighbouring mines, shared infrastructure and more efficient use of existing mineral districts.

The Metalnomist Commentary

The Anglo-Codelco agreement shows that the next wave of copper growth may come from optimising existing mining districts rather than building entirely new mines. In a market facing long permitting cycles and higher capital costs, adjacent-resource integration can unlock meaningful supply at lower risk.

Argentina Lithium Growth Could Challenge Chile’s Regional Lead

Argentina Lithium

Argentina lithium growth could reshape Latin America’s lithium map over the next decade as new projects advance under more investor-friendly rules. Argentina is expected to match Chile’s lithium output by 2035, with some industry participants arguing it could overtake Chile even earlier.

Argentina lithium growth is being supported by faster permitting, large brine resources and stronger investment incentives. By contrast, Chile’s lithium expansion remains constrained by restrictive legislation, lengthy approval processes and uncertainty around new project development.

Argentina lithium growth is strategically important because lithium remains central to electric vehicles, energy storage and battery supply chains. Global buyers want large-scale, politically stable and western hemisphere supply outside more exposed jurisdictions.

Chile remains the region’s largest producer today. However, its future output growth depends heavily on existing producers and slow-moving new projects, while Argentina has a deeper pipeline of advanced developments.

Chile’s Lithium Policy Slows New Supply

Chile has long been Latin America’s dominant lithium producer, but its regulatory system is limiting new investment. Lithium remains non-concessionable and is still treated under legislation linked to nuclear materials.

Companies seeking to extract lithium in Chile must apply for special mining contracts. These contracts are granted through public bidding processes that can be lengthy, bureaucratic and uncertain.

This creates a major exploration problem. Companies may be reluctant to explore land if they cannot be confident of later securing extraction rights.

Chile’s national lithium strategy also requires all new projects to use direct lithium extraction. DLE is viewed as more environmentally friendly than traditional evaporation ponds, but it creates technical and cost challenges.

Each DLE process must be designed around the specific chemistry of each brine resource. That means technology used at one salar cannot simply be copied at another.

This raises development costs and lengthens project timelines. Industry participants estimate that DLE projects may require investment of up to $44,000 per tonne of lithium carbonate equivalent, compared with about $26,000/t for evaporation projects.

Chile’s new supply pipeline is therefore moving slowly. The first major new project, Rio Tinto’s Maricunga, is expected only by the end of 2030, with another new project expected in 2032.

Until then, Chile may rely mainly on capacity increases from existing producers. That could limit its ability to respond to rising lithium demand if Argentina’s project pipeline accelerates.

Argentina’s Rigi Regime Attracts Lithium Capital

Argentina is moving in the opposite direction. Its government has streamlined licensing and introduced the Rigi incentive regime for large investments.

Rigi provides tax exemptions, import-export benefits and legal protections for approved projects. It also allows companies to settle certain disputes in courts outside Argentina, improving investor confidence.

Ten lithium projects have already applied to Rigi, with three approved. The programme has become a major signal to international investors seeking policy stability and faster project execution.

Argentina now has more than 60 active lithium projects and seven producing assets, the most in Latin America. Two new developments are expected to come on line this year, lifting projected output to 159,000t of lithium carbonate equivalent.

That remains below Chile’s 305,000t in 2024. However, Argentina has more than 20 projects in advanced stages, including eight close to production.

Argentina’s mining ministry expects output to reach 583,000 t/yr of lithium carbonate equivalent by 2035. That would put the country in position to match or overtake Chile if Chile’s permitting regime does not change.

The investment logic is clear. Argentina offers large brine resources, a more open policy framework and exposure to western hemisphere supply chains. That combination is increasingly attractive to battery makers, automakers and mining companies.

Chile still has enormous lithium potential. But potential alone does not create supply. Without faster approvals and clearer rules, Chile risks losing regional leadership to Argentina.

For the lithium market, this shift matters. Argentina’s rise could increase competition, diversify supply and give buyers more options in South America. It could also make Latin America’s lithium growth less dependent on Chile’s policy choices.

The Metalnomist Commentary

Argentina’s lithium advantage is not only geological; it is regulatory. Chile still has world-class resources, but Argentina is turning policy speed into supply-chain momentum.

Eramet Argentina Lithium Plant Reaches 80% Capacity as Ramp-Up Recovers

Eramet Argentina Lithium Plant

Eramet Argentina lithium plant performance improved sharply in March as the Centenario-Ratones project reached around 80% of its designed capacity. The French mining group said the plant operated near 80% of its 24,000 t/yr nameplate capacity after recovering from February production setbacks.

The Eramet Argentina lithium plant is strategically important because Argentina is becoming one of the fastest-growing lithium supply regions globally. Stronger output from Centenario-Ratones supports the country’s push to challenge Chile’s long-standing lithium leadership.

The Eramet Argentina lithium plant produced 3,720t of lithium carbonate in the first quarter. Output was limited by downstream equipment shutdowns and natural gas supply constraints, but operations normalised in March.

Centenario-Ratones Recovers After February Disruptions

Eramet temporarily shut part of its downstream equipment in February for an extended period. The work was designed to implement improvements and support the ramp-up process.

Natural gas supply constraints also limited production during the quarter. These disruptions show that lithium brine projects depend not only on resource quality, but also on reliable processing equipment and energy supply.

Centenario-Ratones achieved its highest production rate to date in March. This suggests the project is moving closer to stable commercial performance after early ramp-up challenges.

The ramp-up is expected to be completed by July at the latest. If achieved, this would strengthen Eramet’s position in Argentina’s lithium supply chain and improve near-term lithium carbonate availability.

Lithium Sales Highlight Stronger Price Environment

Eramet sold 3,920t of lithium carbonate in the first quarter, generating €57mn in revenue. That implies an average realised price of roughly $16,986/t.

The first-quarter lithium revenue already exceeded Eramet’s lithium revenue for all of 2025. This highlights the impact of stronger lithium carbonate prices and improving sales volumes.

The result matters for project economics. Higher lithium prices can support ramp-up costs, equipment improvements and working capital needs during the early production phase.

For Argentina, Centenario-Ratones adds to a growing pipeline of lithium projects backed by more investor-friendly policies. Successful ramp-up would reinforce Argentina’s role as a major future source of lithium carbonate for battery supply chains.

The Metalnomist Commentary

Centenario-Ratones shows both the opportunity and execution risk in Argentina’s lithium growth story. Strong prices improve project economics, but stable energy supply and processing reliability will decide whether ramp-up targets become sustained production.

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.

Codelco Copper Performance Faces Review Under Chile’s Kast Administration

Codelco

Codelco copper performance will come under tougher scrutiny as Chile’s new administration prepares to review the state-controlled miner’s finances, management and operational execution. Economy and mining minister Daniel Mas said the government will take a “very critical look” at Codelco to ensure it remains a major national company.

Codelco copper performance matters because the company remains one of the world’s largest copper producers, with direct output of 1.3mn t in 2025 and 1.4mn t including its share in non-operated mines. Any operational weakness at Codelco has direct implications for Chile’s copper supply, fiscal revenue and global refined copper expectations.

Codelco copper performance has also become a political issue because the company faces rising debt, safety concerns and cost overruns at major mine-life extension projects. The shareholder review scheduled for 20 April will focus on areas requiring concrete measures to improve performance.

Debt, Cost Overruns and Mine Projects Drive Government Scrutiny

The Kast administration’s review will examine Codelco’s financial position, management quality, safety record and project execution. Mas pointed to cost overruns tied to the renovation of Codelco’s corporate offices in Santiago and major investments at Rajo Inca and Chuquicamata underground.

These projects are strategically important because they support mine-life extensions at core Chilean copper assets. However, overruns can pressure capital discipline at a time when copper producers already face higher costs, lower ore grades and more complex underground development.

Mas also highlighted Codelco’s debt burden. The company took on $8.7bn in debt to help finance around $7bn in contributions to the state between 2022 and 2025, creating tension between its role as a national revenue source and its need to reinvest in production stability.

Lithium Strategy Review Adds Another Layer to Codelco’s Role

The government also plans to review Chile’s national lithium strategy inherited from the previous administration. However, Mas said the Codelco-SQM lithium venture will have security to operate if all legal stages have been completed.

Chile’s comptroller general approved the joint venture in December 2025, which was regarded as the final condition for the deal. The transaction gives Codelco 50% plus one share in Nova Lithium, the joint venture with SQM.

Mas argued that Codelco’s 2025 profit of $2.4bn was not a pure copper result, because only $388mn came from copper sales. The rest came mainly from the fair value of the SQM-linked lithium acquisition, adding to debate over how Codelco’s performance should be measured.

The Metalnomist Commentary

Chile’s review of Codelco shows that national copper champions face rising pressure to prove operational discipline, not only resource ownership. The bigger issue is whether Codelco can fund copper renewal, manage lithium expansion and still deliver fiscal value to the state.

 

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.

Codelco Copper Output Stabilises as Middle East Crisis Raises Cost Risk

Codelco

Codelco copper output stabilised in 2025, but rising energy, diesel, reagent and logistics costs linked to the Middle East crisis could complicate the company’s recovery path. Chile’s state-owned copper producer reported a 0.5% increase in copper output to 1.33mn t, while total attributable production reached 1.44mn t.

The modest improvement showed that Codelco copper output has started to recover after several years of operational pressure. However, the company still faced mixed performance across major divisions, including lower output at El Teniente, Chuquicamata and Gabriela Mistral.

Codelco copper output is expected to rise only slightly in 2026 to 1.331mn–1.357mn t. That guidance highlights the limited pace of supply growth at one of the world’s most important copper producers, even as demand from grids, electrification and industrial investment remains structurally strong.

Fuel and Sulphuric Acid Costs Threaten Copper Margins

The Middle East crisis is creating a new cost risk for copper producers. If disruption around the Strait of Hormuz persists, higher diesel prices, tighter logistics and rising input costs could feed directly into mining cost structures.

Diesel is a key cost driver for haulage, power generation, processing and mine-site operations. Market participants estimate that copper mining costs can rise by 5–10% for every $50/bl increase in oil prices, making fuel volatility a direct margin threat.

Sulphur supply is another concern because it is used to produce sulphuric acid for copper leaching. This risk is especially acute for hydrometallurgical producers in the African Copperbelt, but higher global acid costs could still affect broader copper market sentiment.

Codelco’s own cost base was already rising before the latest geopolitical shock. Direct cash costs increased 4.8% to $2.09/lb in 2025, while total costs rose 14% to $3.73/lb because of higher operating activity, exchange-rate effects and inflation.

Stable Output Masks Deeper Structural Pressure

Codelco described 2025 as a year of stabilisation and productive transition. Ministro Hales lifted output by 25% to 153,000t, while Radomiro Tomic increased production by 9.2% to 295,000t.

However, several core assets remained under pressure. El Teniente output fell 13% to 310,000t, Chuquicamata declined 8% to 265,800t, and Gabriela Mistral dropped 20% to 82,000t.

The company also reported record capital expenditure of $5.07bn in 2025, showing the rising investment required to sustain production. Deeper deposits, lower ore grades and more complex operations are making copper supply more capital-intensive.

This reinforces the longer-term copper supply challenge. Even with stabilising production, Codelco’s guidance points to only incremental growth, while cost inflation could delay marginal projects and pressure higher-cost operations if the conflict continues.

The Metalnomist Commentary

Codelco’s results show that copper supply risk is shifting from simple output loss to cost inflation and capital intensity. The market may still focus on tonnes, but diesel, sulphuric acid and project execution costs will increasingly decide how much copper supply can grow profitably.

US Chile Critical Minerals Talks Signal New Supply Chain Reset

US Chile Critical Minerals

US Chile critical minerals cooperation is moving onto a formal diplomatic track after the two countries signed a joint declaration to begin discussions on critical minerals and rare earths. The agreement was signed in Santiago during a meeting between Chilean president José Antonio Kast and US deputy secretary of state Christopher Landau.

US Chile critical minerals talks will focus on mechanisms to strengthen supply chains for strategic raw materials. Chile’s foreign affairs ministry said technical teams will examine projects of interest, scrap management for critical minerals and rare earths, and public-private financing mechanisms.

US Chile critical minerals cooperation carries direct industrial importance because Chile is one of the world’s most important resource economies. The country is the largest global copper producer and the third-largest lithium producer, while its large lithium reserves remain underdeveloped because of long-standing legal restrictions.

Chile’s Copper and Lithium Base Gives the Talks Strategic Weight

Chile’s mineral position gives the US a clear reason to rebuild cooperation. Copper is central to power grids, electrification, data centers, renewable energy, industrial equipment, and defense systems. Lithium remains essential for batteries, energy storage, and electric vehicles.

The new talks also include rare earths and scrap management. That broader scope suggests the discussions are not limited to mining projects. They may also cover recycling, secondary raw materials, processing routes, and financing structures that can support a more resilient supply chain.

Chile’s untapped lithium potential is especially important. The country has the world’s largest lithium reserves, but development has been constrained by legacy laws and policy limits. If cooperation creates more investable project structures, Chile could become a more active pillar in allied battery material supply.

US Policy Shift Reopens a Critical Minerals Channel With Chile

The declaration also marks a reset in US-Chile relations after a tense period under former president Gabriel Boric. Washington had moved ahead with critical minerals partnerships with other allies earlier this year, but Chile was not included in the initial initiative.

That omission made Chile’s absence notable. Any serious Western critical minerals strategy is difficult to build without Chile because of its copper and lithium position. The new declaration therefore signals a practical return to resource diplomacy.

For Chile, the discussions could open access to financing, technology, and downstream partnerships. For the US, they offer a pathway to reduce exposure to concentrated supply chains and secure materials needed for industrial competitiveness, energy security, and defense resilience.

The Metalnomist Commentary

The US cannot build a credible critical minerals strategy without Chile. The key question is whether this declaration becomes a real project-financing framework or remains another diplomatic signal without industrial execution.

Codelco Rio Tinto Partnership Targets Faster Mining Development in Chile

Codelco Rio Tinto Partnership

Codelco Rio Tinto partnership plans could accelerate major mining development in Chile as the state-owned copper and lithium group seeks deeper cooperation with global miners. The preliminary agreement will focus on identifying joint investment opportunities in large-scale mining projects across the country.

Codelco and Rio Tinto will create an executive committee made up of senior officials from both companies. The committee will identify prospective pilot projects, assess major mining opportunities, and oversee implementation where cooperation advances.

The Codelco Rio Tinto partnership reflects a broader strategic shift inside Chile’s mining sector. Codelco wants to accelerate timelines, reduce costs, and improve ESG compliance by sharing technical knowledge with established international mining companies.

Chile Turns to Partnerships to Unlock Copper and Lithium Growth

Chile remains one of the world’s most important copper producers, but project development has become more difficult. Lower ore grades, permitting complexity, water constraints, community expectations, and capital intensity are increasing the pressure on producers.

Codelco’s partnership strategy aims to address those constraints. By working with companies such as Rio Tinto, the Chilean state miner can access technical expertise, operational experience, project discipline, and global capital networks. This could help move exploration and development projects faster.

The agreement also builds on Codelco’s recent cooperation with other major miners. The company partnered with BHP last year to enhance copper exploration in the Antofagasta region. This suggests Codelco may pursue more private-sector alliances as Chile works to protect its long-term copper output.

Rio Tinto Ties Strengthen Chile’s Critical Minerals Platform

Rio Tinto and Codelco have already been strengthening their relationship through work on the Maricunga lithium project and the Nuevo Cobre region. The new agreement broadens that cooperation and positions both companies to explore additional copper and lithium opportunities.

This matters because Chile is central to both traditional mining and the energy transition supply chain. Copper remains essential for power grids, electrification, EVs, renewables, and industrial infrastructure. Lithium remains strategically important for batteries and energy storage.

The Codelco Rio Tinto partnership therefore carries value beyond individual projects. It signals that Chile’s mining future may depend increasingly on structured cooperation between state-owned champions and global mining companies with advanced technical and ESG capabilities.

The Metalnomist Commentary

Codelco’s partnership model shows that Chile understands the limits of going alone in a more complex mining environment. The next competitive advantage will come from faster permitting, stronger technical execution, and alliances that can turn resource potential into reliable supply.

Codelco Lithium Ascotan Move Expands Chile’s Strategic Control Over New Brine Assets

Codelco Lithium

Codelco lithium Ascotan plans mark another important step in Chile’s effort to keep stronger state influence over future lithium supply. Codelco and Quiborax formed a joint venture called Minera Ascotan and applied for a special lithium operating contract. That contract is required for lithium extraction in Chile. As a result, Codelco lithium Ascotan plans now sit at the center of Chile lithium strategy.

This move matters because Ascotan is not a minor asset. The salt flat is described as the third largest lithium reserve in Chile. That gives the project long-term strategic value inside one of the world’s most important lithium jurisdictions. Therefore, Codelco lithium Ascotan plans strengthen the state miner’s growing role in Chile’s next lithium phase.

The structure of the deal also reveals the political logic. Chile’s current framework requires public-private partnerships so the state can retain control while private capital supports development. That model has been in place since 2023 under the CEOL-based lithium strategy. Consequently, Chile lithium public-private partnership is now the main route for new project access.

Ascotan Salt Flat Adds to Codelco’s Expanding Lithium Portfolio

Ascotan salt flat adds another major asset to Codelco’s widening lithium position. The state miner is already set to become the majority owner in SQM’s Atacama operations from 2031. It is also advancing its partnership with Rio Tinto at Maricunga. As a result, Codelco lithium Ascotan plans are part of a broader portfolio build, not a standalone move.

That portfolio strategy matters because Chile wants more than royalty exposure from lithium. It wants stronger long-term participation in ownership, production, and strategic decision-making. Codelco is clearly becoming the state’s main operating vehicle for that ambition. Therefore, Ascotan salt flat could become another pillar in Chile’s effort to shape its own lithium future more directly.

The Quiborax partnership appears tactical as well as commercial. The article suggests Codelco likely chose a non-mining partner to secure the CEOL process more quickly. That reflects rising urgency ahead of a political transition. Meanwhile, it shows how project structure can be shaped by policy timing as much as geology.

Chile Lithium Strategy Faces a Political Test as New Leadership Nears

Chile lithium strategy now faces a more uncertain political backdrop. The article notes that incoming president Jose Antonio Kast has shown willingness to change the country’s lithium mining policy. He is scheduled to take office on 11 March. As a result, Codelco lithium Ascotan plans may also be an effort to lock in strategic progress before policy direction potentially changes.

The future ownership structure also remains important. Quiborax currently holds 66pc of the joint venture, but both initial partners are expected to make room for a new majority owner once the CEOL is granted. That new partner would be responsible for developing the project. Therefore, Chile lithium public-private partnership will remain central even if Codelco keeps strategic influence.

This makes the Ascotan move significant for the wider market. It shows Chile is still pushing forward with a state-guided lithium model, even as political uncertainty grows. If Codelco continues adding assets at this pace, Boric’s vision of making it Chile’s leading lithium producer could become more credible than many expected.

The Metalnomist Commentary

This move matters because it shows Chile is still trying to build lithium control through structure, not just ownership slogans. Codelco is becoming the state’s main instrument for that strategy. If Ascotan advances, Chile may prove that public-private lithium development can still move forward even in a changing political environment.

Policy change in Argentina may boost Copper mining by revising glacier protections

Policy change in Argentina may boost Copper mining as the government reviews glacier protection rules. Javier Milei says unclear glacier boundaries block investment and resource development. The review targets the Glaciers Law and the perimeter criteria set by IANIGLA. Meanwhile, miners seek legal certainty near the Andes where deposits meet protected zones.

Glacier boundary authority could shift to provinces

The proposal would let provinces define glacier perimeters instead of federal technical mapping. Supporters say clearer zones could unlock projects while protecting core ice. However, critics warn looser definitions could expand mining into sensitive watersheds. Meltwater from glacier systems supports rivers and agriculture across the country.

Copper projects and incentives drive investor interest

Large copper projects in San Juan Province could benefit if permitted areas expand. The list includes BHP and Lundin Mining’s Vicuña Project, plus Glencore’s El Pachón.

The RIGI program offers tax breaks and 40-year legal stability for large projects. Therefore, policy clarity plus RIGI could narrow the gap with Chile’s export scale. Rio Tinto cites stability guarantees as a key reason it entered the country, said Jakob Stausholm. Policy change in Argentina may boost Copper mining if congress rewrites the boundary framework. However, lawmakers must weigh investment gains against water-security and social-license risk.

The Metalnomist Commentary

Argentina’s copper upside is real, but the reform must survive court and community scrutiny. Meanwhile, investors will price permitting risk until provinces publish transparent glacier maps. Therefore, the best outcome couples faster approvals with verified safeguards for meltwater.

US-China critical minerals trade masks big strategic risks

US-China Critical minerals

The US-China critical minerals trade looks small in dollar terms but carries outsized strategic risks for key industries. The US-China critical minerals trade was worth just $2bn in 2024, only 3pc of US critical mineral imports. However, the US-China critical minerals trade underpins defence, high-tech manufacturing and energy systems that generate trillions in economic value.

Small trade volumes, large exposure to China

Macquarie research shows US critical mineral imports totalled $65bn in 2024 under the new 60-mineral list. Bulk materials like aluminium, copper and PGMs dominate the import bill and come mainly from partners such as Canada and Chile. By contrast, China supplied only $2bn, far below Canada’s $21bn or Chile’s $6.6bn.

However, China’s leverage rests in concentration, not value. It controls about 70pc of global rare earth mining and 90pc of processing. As a result, even small tonnages of Chinese exports can be mission-critical for US defence and advanced manufacturing. Any targeted export controls could therefore disrupt high-value supply chains well beyond the trade numbers.

Export controls could hit US GDP and strategic sectors

Macquarie estimates Chinese export controls on select minerals could each cut US GDP by more than $1bn in a year. Samarium restrictions show the highest impact, at an estimated $4.5bn loss, because of its critical role in defence. Meanwhile, curbs on lutetium could shave $2.1bn from GDP, mainly affecting refineries and semiconductor producers.

Controls on terbium, dysprosium and gallium would similarly reverberate across magnets, EV motors, wind turbines and high-frequency electronics. Therefore the economic risk from the US-China critical minerals trade lies in concentrated choke points, not headline trade flows. That reality is now shaping US industrial policy, stockpiling strategies and onshoring of processing capacity.

The Metalnomist Commentary

This analysis reinforces why Washington treats rare earths and related metals as strategic assets, not simple commodities. Even modest Chinese export controls could ripple through defence, semiconductor and energy transition value chains. Expect continued moves by the US and allies to diversify sourcing, build domestic refining and expand recycling to reduce this asymmetric exposure.

Chile lithium mining license moves forward under private–indigenous JV model

Chile lithium mining

Chile lithium mining license dynamics are shifting as a private–indigenous joint venture moves first in the new Ollagüe process. The Chile lithium mining license application was filed by Kuska Minerals, a JV between Canada’s Wealth Minerals and the Quechua Indigenous Community of Ollagüe. The Chile lithium mining license bid positions Kuska as an early mover in a basin that the government already classed as high potential in 2024. By partnering with the CIQO, Wealth aligns directly with Chile’s requirement for agreements with affected native communities. This structure also helps the company streamline its own consultation process while offering the community a 5pc equity stake in future value.

Indigenous partnership reshapes Ollagüe lithium approvals

Chile now places indigenous consultation at the centre of lithium approvals, and the Ollagüe salt flat shows how this works in practice. Authorities recently completed native consultations that remapped the exploitable area to protect culturally sensitive zones and populated areas. As a result, the mining ministry opened a fresh application round focused on the remaining brine resources. Kuska is, so far, the only bidder to publicly submit an official application for this high-altitude basin. The JV is now verifying that it meets every technical and legal criterion and has committed to comply fully before the undisclosed deadline. This early alignment with both state and community expectations should reduce project risk if the license advances to the next stage.

Faster licensing supports Chile’s lithium expansion strategy

Chile is using a streamlined process in Ollagüe to accelerate lithium supply while preserving regulatory control. Officials expect the new licensing window to move relatively quickly, signalling to investors that administrative reforms are starting to bite. At the same time, the country has already approved seven other lithium-related permits this year, including projects linked to Eramet, a JV with Quiborax and Codelco, and two Rio Tinto applications. These approvals affirm Chile’s intent to turn selected salars into bankable projects, rather than leaving resources stranded amid policy debate. For downstream battery and EV supply chains, the Ollagüe basin could become another node in a diversified, ESG-sensitive lithium portfolio if Kuska’s bid succeeds.

The Metalnomist Commentary

Kuska’s structure shows how future lithium developers in Chile may need to blend foreign capital, state oversight and genuine indigenous participation. If this model delivers both social licence and predictable approvals, it could become a template for other high-potential salars. Global buyers should watch Ollagüe closely, as community-anchored licensing could shape both cost structures and long-term offtake security.

Chile lithium contract with Enami anchors new national strategy

Chile lithium mining

Chile lithium contract with Enami marks a major step in the country’s new lithium strategy. The agreement grants Enami rights over the Altoandinos salt flat, Chile’s largest undeveloped lithium deposit. It also establishes the first special lithium operation contract, known locally as a Ceol, under Boric’s strategy.

Altoandinos salt flat and Chile’s lithium strategy

The Chile lithium contract with Enami runs until 2060 and targets production starting around 2032–2034. Enami and partner Rio Tinto plan to develop the Aguilar, Grande and La Isla salt flats. The state miner reports 15mn tonnes of lithium carbonate equivalent, significantly above Chile’s published resource base. As a result, Altoandinos could become a flagship asset within Chile’s broader national lithium strategy.

Chile lithium contract with Enami operates within a strict strategic resource and nuclear oversight framework. Laws from the 1970s and 1980s classify lithium as strategic and limit purely private concessions. Therefore, Ceols must pass review by the nuclear energy commission and other state institutions before development. This framework aims to capture more value for Chile while controlling environmental and social risks in the Atacama.

Global EV supply chains and Chile’s lithium leadership

Chile remains the world’s second largest lithium producer, anchored by SQM and Albemarle in the Atacama salt flat. However, the Chile lithium contract with Enami shows how future growth will rely more on state led partnerships. The Altoandinos project can diversify production beyond the core Atacama operations and support long term export revenues. Meanwhile, global battery and EV manufacturers will view this contract as an important new source of high grade brine.

Competition for secure lithium supply will intensify as more countries classify the metal as strategic. Therefore, Chile lithium contract with Enami sends a strong signal to investors about policy direction and project pipeline. International partners must understand the state’s central role, longer development timelines and heightened community expectations. As a result, any Altoandinos timetable slippage could reshape global supply expectations for EV batteries and energy storage.

The Metalnomist Commentary

Chile’s new contracting model blends resource nationalism with pragmatic partnerships across the lithium value chain. Investors that align with this approach and accept higher state involvement may gain durable exposure to premium brine assets. Yet they must also plan for stricter governance, evolving royalty regimes and closer scrutiny from global downstream customers.

Codelco Lowers 2025 Copper Guidance at El Teniente

Codelco mine

Codelco lowers 2025 copper guidance at El Teniente after a fatal seismic incident. The pause removed 33,000t from output and lifted losses to $340mn. Therefore, Codelco lowers 2025 copper guidance at El Teniente as damaged sectors remain offline. Guidance updates will follow in the coming days.

Operations are only partly restored while several zones stay halted. Recursos Norte, Andesita, Andes Norte, and Diamante face structural damage. Meanwhile, ore movements resumed, with 76,400t sent to Colon and 9,900t to Sewell. As a result, Codelco lowers 2025 copper guidance at El Teniente despite incremental throughput.

Safety, Timeline, and Production Impact

The incident occurred on 31 July after an earthquake triggered a rockfall. Six workers tragically lost their lives in the Andesita region. The mine is the world’s largest underground copper operation. However, full-area inspections continue to constrain mining fronts. Therefore, 2025 guidance must reflect narrower access and slower sequencing.

Market Implications and Near-Term Priorities

Copper supply risk rises as Chile’s flagship asset pares plans. Price effects hinge on the duration of sector closures and mill feed. Codelco prioritizes geotechnical remediation and safe restart protocols. As a result, near-term volumes rely on alternative stopes and stockpiles. Investors should track repair milestones and concentrator stability.

The Metalnomist Commentary

This cut reinforces how geotechnical shocks can reshape copper balance sheets fast. Expect tighter Chilean guidance until remediation unlocks high-grade panels. Watch repair cadence, dilution control, and smelter feed quality into 2025.

Chile Leads Global Lithium and Copper Exports in 2024

Chile Copper Mining

Copper exports strengthen Chile’s global leadership

Chile maintained its position as the world’s leading copper exporter in 2024, driving both value and volume. The Chile lithium and copper exports reached over $50bn, accounting for 15pc of global copper trade, according to Subrei. The country produced 5.3mn t of copper, or 23pc of global output, with state-owned Codelco contributing 1.44mn t. Chile dominated shipments of copper concentrates and cathodes, with the EU sourcing 39pc of its cathode imports from Chile and India receiving a third of its concentrates from Chilean producers.

Lithium exports secure global dominance

Although second to Australia in lithium production, Chile led the world in lithium carbonate equivalent (LCE) exports. The Chile lithium and copper exports accounted for 78pc of global LCE trade, worth $2.6bn. Chile produced 285,000t of LCE in 2024, with SQM maintaining exclusive production and sales of lithium hydroxide domestically. Major markets for Chile’s LCE included China, the US, the EU and Japan, while lithium hydroxide exports were focused on Brazil and the US.

Chile also led in molybdenum, securing the top spot in exports of molybdenum oxides and hydroxides with a 40pc share, and roasted oxides with 33pc of global trade. It ranked fourth globally in ferro-molybdenum exports, reinforcing its role as a critical supplier of strategic minerals.

The Metalnomist Commentary

Chile’s dual dominance in lithium and copper exports highlights its pivotal role in global supply chains for energy transition metals. However, this dependence on a narrow set of commodities exposes the country to price volatility and geopolitical risk. Strategic investment in downstream processing and value-added production could strengthen Chile’s industrial resilience.

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.

Chile Advances Direct Lithium Extraction Technology at Altoandinos

Enami

Breakthrough in Lithium Recovery and Sustainability

Chilean state-owned miner Enami has reported promising results from testing direct lithium extraction (DLE) technology at its Altoandinos project, the country’s largest undeveloped lithium deposit. Eight international laboratories participated in the tests, which demonstrated a dramatic reduction in water consumption to 36m³ per metric tonne of lithium carbonate equivalent (LCE) — 55 times less than conventional evaporation pond methods. Lithium recoveries also improved sharply, rising from 42% in traditional processes to an average of 92%.

The DLE method also reduces land use, with a proposed 75,000t per year plant requiring only 10 hectares compared with 1,020 hectares for evaporation ponds. This efficiency addresses one of the key environmental challenges facing Chile’s salt lake ecosystems, which have been under increasing scrutiny from environmental groups and regulators.

Strategic Project Development with Rio Tinto

Enami plans to invest around $3 billion to develop Altoandinos in northern Chile’s Atacama region in partnership with Anglo-Australian mining giant Rio Tinto. The deposit hosts an estimated 15 million tonnes of LCE resources across the Aguilar, La Isla, and Grande salt lakes. Agreements have been secured with six indigenous communities in the region, ensuring local stakeholder involvement in the project’s advancement.

This initiative aligns with Chile’s national lithium strategy, launched in April 2023, which targets increased lithium production while safeguarding fragile salt lake ecosystems. The strategy mandates a transition from evaporation-based extraction to DLE and sets a goal of protecting at least 30% of salt lake environments.

The Metalnomist Commentary

Chile’s successful DLE test results could significantly reshape the global lithium supply chain by lowering environmental impacts while boosting yields. If scaled effectively, Altoandinos could emerge as a model for sustainable lithium production, positioning Chile as a leader in both output and ecological stewardship. The real test will be maintaining these efficiencies at commercial scale while navigating regulatory and community engagement challenges.

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.
