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.

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.

Rio Tinto Argentina Lithium Incentives Expand Fenix Growth Plan

Rio Tinto Argentina Lithium

Rio Tinto Argentina lithium incentives have strengthened again after Argentina approved the company’s $530 million expansion of the Fenix lithium project under its large-investment incentive regime. The approval marks Rio Tinto’s second lithium project accepted under Rigi, reinforcing Argentina’s role in the group’s battery materials strategy.

The Fenix expansion is expected to add 9,500 t/yr of lithium carbonate equivalent production capacity. Once completed, total output from the project is expected to reach around 41,500 t/yr.

Rio Tinto Argentina lithium incentives also support the company’s broader target to produce 200,000 t/yr of lithium carbonate equivalent by 2028. Most of that output is expected to come from Argentina, where Rio Tinto significantly expanded its position through the acquisition of Arcadium Lithium assets.

Fenix Expansion Adds Capacity to a Long-Running Lithium Asset

The Fenix project has operated in Catamarca province since 1997 and currently has nameplate capacity of 32,000 t/yr. The approved expansion adds new production to an established asset, reducing some of the execution risk compared with a fully greenfield project.

Argentina’s economy minister Luis Caputo said the new build would add $165 million to Fenix’s annual revenue from lithium carbonate equivalent sales. This gives the expansion clear commercial weight at a time when lithium producers are prioritising scale, cost control, and project discipline.

The approval also follows Rio Tinto’s earlier Rigi acceptance for Rincon. That $2.7 billion project is designed for 60,000 t/yr of lithium output and is expected to become the company’s future flagship lithium operation in Argentina.

Rigi Gives Argentina a Stronger Lithium Investment Platform

Rigi has become a central part of Argentina’s strategy to attract large-scale mining investment. The regime grants exemptions from value-added and import-export taxes, offers legal protections, and guarantees 30 years of regulatory stability.

That stability is especially important in lithium, where projects require large capital commitments, long permitting timelines, and confidence in tax and export rules. For Rio Tinto, Rigi helped support the investment case for deeper exposure to Argentina’s lithium sector.

The company’s former chief executive Jakob Stausholm said Rigi was one of the main reasons behind his confidence in acquiring Arcadium Lithium’s Argentine assets. That shows how fiscal and legal stability can directly influence global mining capital allocation.

The Metalnomist Commentary

Argentina is using Rigi to convert lithium resource potential into project commitments from major global miners. Rio Tinto’s second approval shows that policy stability can become as important as geology when battery metal producers decide where to invest.

Argentina Lithium Production Push Strengthens Critical Minerals Growth Strategy

Daniel Gonzalez

Argentina lithium production is accelerating as the country seeks to become one of the world’s leading suppliers of battery materials. Vice-minister of energy and mining Daniel Gonzalez said Argentina is now the fastest-growing lithium producer and expects the country to become the largest soon.

The government has raised Argentina’s estimated lithium reserves to 23mn t of lithium carbonate equivalent. It has also increased its copper reserve estimate by 3mn t since last September, strengthening the country’s position across two key energy transition metals.

Argentina lithium production is being expanded by companies including Rio Tinto, Ganfeng, Lithium Argentina and Posco. At the same time, the country is working to develop four greenfield copper projects that could create a new large-scale copper industry.

Lithium Growth Positions Argentina as a Battery Materials Powerhouse

Argentina’s lithium growth reflects the strategic importance of its brine resources in the global battery supply chain. Demand from electric vehicles, energy storage and battery manufacturing continues to support long-term interest in secure lithium carbonate and lithium hydroxide supply.

The country’s larger reserve estimate improves its investment case. It gives developers, battery manufacturers and downstream customers more confidence that Argentina can support long-term production growth.

However, reserve scale alone will not guarantee success. Argentina must convert projects into reliable production, build infrastructure, manage water and permitting risks, and maintain stable rules for foreign investors.

Copper Ambition Adds Depth to Argentina’s Mining Strategy

Argentina is also targeting major copper growth. Gonzalez said the country aims to produce 1.5mn-2mn t of copper over the next five to seven years, supported by four greenfield projects now under development.

This copper ambition is significant because copper is central to grids, electrification, renewable energy, electric vehicles and industrial infrastructure. If Argentina can deliver new copper output, it could become a more important supplier to global energy transition supply chains.

The government is using tax incentives to attract investment. These include a lower income tax rate, no tariffs on imports, no export duties, and 30 years of regulatory and tax stability.

Still, investor confidence remains the key challenge. Argentina is trying to recover from years of policy volatility and economic mismanagement, while the cost of capital remains high. Lower financing costs will be essential if the country wants to move large lithium and copper projects from ambition to production.

The Metalnomist Commentary

Argentina has the mineral base to become a major lithium and copper supplier, but geology is only the starting point. The real test will be whether tax stability, investor trust and project execution can overcome the country’s long history of policy risk.

Josemaria Copper Offtake Transfer Strengthens Mitsui’s Position in Argentina Supply Chain

Jogmec

Josemaria copper offtake rights have become a strategic supply-chain asset for Japan after state-owned Jogmec transferred its 40% copper concentrate offtake option from Argentina’s Josemaria project to Mitsui. The transfer gives the Japanese trading house potential access to a large future copper concentrate stream from one of South America’s key emerging copper districts.

Jogmec awarded the option through a competitive bidding process. The agency had retained the offtake right after participating in joint exploration around the Josemaria area from 2009 to 2017. Although the transaction value was not disclosed, the industrial significance is clear. Japan is trying to secure copper raw materials before energy transition demand tightens global competition.

The Josemaria project is being developed by Vicuña Corp, a joint venture between Lundin Mining and BHP. Vicuña is also studying integrated development with the nearby Filo del Sol deposit, creating the potential for a larger copper district in Argentina’s San Juan province.

Mitsui Gains Access to a Meaningful Copper Concentrate Stream

The Josemaria copper offtake option could give Mitsui access to 40% of future concentrate output from the deposit. Vicuña estimates Josemaria could produce about 715,000 tonnes per year of copper concentrate during the first six years of operations.

That 40% share would equal around 286,000 tonnes per year of concentrate. Jogmec said this volume corresponds to roughly 77,000 tonnes per year of contained copper. For Japan, this is not a minor allocation. It would represent about 6.16% of the country’s projected copper concentrate imports in 2025.

The transfer therefore gives Mitsui a potentially important position in long-term copper procurement. It also reinforces the role of Japanese trading houses as strategic intermediaries between mine developers, smelters, and industrial consumers.

Japan Moves to Diversify Copper Supply as Demand Rises

Japan’s copper supply strategy is becoming more urgent as electrification, digital infrastructure, renewable power, data centers, and grid investment increase copper intensity. These sectors require stable flows of copper concentrate for smelting and refining, making upstream offtake access more valuable.

The Josemaria copper offtake transfer also reflects a broader shift in resource security policy. Japan does not have large domestic copper mine supply, so overseas mine partnerships and offtake rights remain central to industrial resilience.

Argentina’s copper sector is increasingly important in this context. Projects such as Josemaria and Filo del Sol could help diversify global concentrate supply away from more mature producing regions. For Japanese companies, securing exposure to this pipeline supports both supply diversification and long-term competitiveness.

The Metalnomist Commentary

The Josemaria copper offtake transfer shows how copper security is moving upstream. For Japan, the key issue is not only price exposure, but access to future concentrate before global demand tightens further.

Argentina Lithium Feedstock Factory Could Cut Costs and Strengthen Local Supply

Argentina Lithium

The Argentina lithium feedstock factory could change the country’s cost structure for lithium brine processing. Tsingshan is preparing to open the plant in Jujuy. The site will produce soda ash and hydrochloric acid locally. As a result, the Argentina lithium feedstock factory could reduce import dependence across the highland lithium sector.

The project matters because reagents are central to lithium brine processing economics. Producers in Argentina still import most chemical inputs. That raises logistics costs and delays deliveries to remote operations. Therefore, local chemical supply could improve both margins and reliability.

Tsingshan has upgraded the Perico facility since July 2023. The plant can produce up to 30,000 metric tonnes per year of soda ash. Hydrochloric acid capacity has not been disclosed. However, even partial local supply would ease pressure on upstream lithium projects.

Local Chemical Supply Could Lower Argentina Lithium Production Costs

Argentina lithium production costs remain structurally high versus Chile. Operators face difficult access routes and limited road infrastructure. That makes reagent transport more expensive. Consequently, Argentina’s operating costs are about 20 percent higher today.

Feedstock demand also shows the scale of the logistics burden. Around 4 tonnes of feedstock are needed for 1 tonne of lithium carbonate. One producer in Salta receives about 20 trucks per day. Therefore, every local tonne of reagent could reduce freight intensity.

The Argentina lithium feedstock factory could improve competitiveness without waiting for major mining expansion. Lower chemical costs would support existing producers first. It could also improve project economics for new entrants. Meanwhile, investors may view local input manufacturing as a positive signal for long-term industrialisation.

Tsingshan Argentina Expands Beyond Chemicals Into Resource Positioning

Tsingshan Argentina is not building only a support asset. The company has also partnered with Jujuy on a lithium project in the Olaroz salt flats. That creates vertical alignment between chemicals and extraction. As a result, Tsingshan could strengthen its position across the regional lithium value chain.

This approach reflects a broader shift in battery materials strategy. Companies increasingly want control over feedstocks, processing, and resource access. Argentina offers scale, but it still needs better industrial support systems. Therefore, reagent localisation may become a model for future investment.

For global supply chains, the message is clear. Lithium competitiveness does not depend only on geology. It also depends on chemicals, roads, and execution. The Argentina lithium feedstock factory highlights how midstream support can reshape upstream economics.

The Metalnomist Commentary

Argentina’s lithium challenge has never been only about resource quality. It has also been about cost inflation caused by imported inputs and weak infrastructure. If this plant performs well, local feedstock production could become one of the country’s most practical competitive advantages.

Argentina glacier law reform advances as Milei targets copper mining growth

Argentina senate

Argentina glacier law reform cleared the Senate in a narrow vote. The bill passed 40–31, above the approval threshold. Argentina glacier law reform now moves to the Chamber of Deputies.

The reform would let provinces classify which glaciers protect water resources. Meanwhile, it would label other ice bodies as “non-functional” for protection. As a result, mining could expand into areas previously off-limits.

Argentina glacier law reform marks the first text change since 2010. The government argues the current framework creates legal uncertainty for investors. Therefore, officials frame the reform as a pro-investment reset for resource development.

What the reform changes for mining permits and copper projects

Argentina glacier law reform shifts decision power toward provincial governments. Provinces could add or remove glaciers from the protected inventory using technical criteria. Meanwhile, the national institute would still maintain the core glacier inventory function.

The biggest commercial impact sits in copper. Several copper resources sit inside current glacier perimeters. Therefore, the reform could unlock exploration permits and feasibility work that stalled under the 2010 framework.

Mining provinces backed the bill strongly during the Senate debate. However, several other provinces opposed the reform. As a result, the Deputies vote could stay tight and highly politicised.

Why water security now sits at the center of copper investment risk

Water risk now defines Argentina’s mining debate. Meltwater supports river basins, irrigation, and long-term supply resilience. Therefore, critics argue Argentina glacier law reform threatens a strategic resource.

Environmental groups and activists also amplified pressure around the vote. Protests already spread across dozens of cities earlier this year. Meanwhile, lawmakers warned the reform may trigger a new wave of demonstrations.

Investors must treat social licence as a project input. However, miners can reduce conflict through transparent hydrology studies and basin-level monitoring. As a result, the strongest projects will pair permits with credible water stewardship.

The Metalnomist Commentary

Argentina glacier law reform could accelerate copper pipelines, but it also raises permitting volatility. The winners will de-risk water early and keep communities inside the data loop. Meanwhile, tight votes signal that policy risk will stay priced into Argentina deals.

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

Argentina Copper Mining

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.

Argentina copper mine investment accelerates under Rigi incentive framework

Argentina copper mine

Argentina copper mine investment is entering a new phase under the Rigi incentive framework. The approval of McEwen Copper’s $2.7bn Los Azules project signals that Argentina copper mine investment is now central to the Milei government’s economic strategy. As a result, Argentina copper mine investment is being positioned as a key pillar for both fiscal reform and long-term export growth.

Rigi turns Los Azules into a flagship Argentina copper mine investment

The Los Azules project is the first copper mine approved under Argentina’s large-scale investment regime, Rigi. The scheme offers a 25pc tax rate instead of 35pc, 30 years of legal stability and exemption from import duties on capital goods. These incentives are designed to de-risk Argentina copper mine investment amid currency volatility and political uncertainty. Construction at Los Azules could begin as early as 2026, subject to permitting approvals. The mine is expected to produce about 175,000 t/yr of copper, placing it among the country’s most significant future producers. This scale matters for Argentina’s balance of payments, because copper exports can provide stable hard-currency revenues.

Copper anchors Argentina’s wider energy and mining investment push

The Los Azules approval is part of a broader Rigi pipeline that already totals $15.7bn in committed projects. The portfolio spans two solar plants, two lithium mines, an oil pipeline, an LNG facility and a steel mill. Together, these projects illustrate how copper, lithium and energy infrastructure are being bundled into a single strategic investment narrative. The government is targeting at least $50bn in energy investment and another $50bn in mining by 2027. That timeline aligns with president Javier Milei’s current term and his wider macroeconomic adjustment agenda. At the same time, Argentina is courting external financial support, including a potential $20bn currency swap backed by the US government. Stable capital inflows are critical to sustain Rigi and reassure foreign mining investors.

The Metalnomist Commentary

Los Azules shows how targeted tax stability and customs relief can unlock large-scale copper capex even in a risky macro environment. The challenge will be execution: permitting, infrastructure delivery and social licence will determine whether this project hits its 2026–27 window. For the global copper market, Argentina’s success or delay at Los Azules will shape future supply expectations in the second half of the decade.

Rio Tinto Rincon lithium project wins Argentina approval to scale production

Argentina Rio Tinto Mining

Argentina cleared the Rio Tinto Rincon lithium project to extract brine and produce lithium. The authorization enables the Rio Tinto Rincon lithium project to ramp toward large-scale output in Salta. As a result, the Rio Tinto Rincon lithium project advances from pilot status to a defined production pathway.

What the approval covers and the build-out timeline

Salta approved extraction and production of 50,000 t/yr of battery-grade lithium carbonate. Authorities granted permits after environmental, water, power, and indigenous consultations. Rio Tinto also benefits from Argentina’s RIGI investment incentives. The company holds clearance to start at 3,000 t/yr in 2028. Ramp-up aims to reach full capacity by 2031.

Strategic context for Argentina’s lithium supply chain

The decision positions Salta among Argentina’s leading lithium hubs. However, the project still must execute drilling, processing, and off-take steps. Meanwhile, provincial oversight and community engagement remain central. As a result, the approval de-risks schedule and financing milestones. It also signals policy support for value-added battery materials.

The Metalnomist Commentary

This approval tightens the pipeline for non-Chinese lithium supply. Watch capex discipline, brine processing yields, and ramp-up reliability. Long lead times mean pricing cycles could shift before peak output arrives.

Glencore Argentina Copper Projects under Rigi Signal $13.5bn Shift

Glencore

Glencore Argentina copper projects under Rigi advance with a $13.5bn plan. The firm seeks Rigi incentives for two mines. The Rigi framework offers 30 years of legal stability. Therefore, Glencore Argentina copper projects under Rigi gain tax and customs relief. The bid is the largest package submitted to date. As a result, Glencore Argentina copper projects under Rigi could reset national copper ambitions.

Rigi Catalysts and Project Scale

Rigi reduces taxes and duties for large investments. It also anchors predictable rules for three decades. Glencore proposes $9.5bn for El Pachón in San Juan. Agua Rica adds $4bn in Catamarca province. Both deposits include copper with gold, molybdenum, and silver. Management praised President Milei’s policy shift. The incentive program launched in 2024 and is expanding.

Argentina’s Copper Reset and Lithium Context

Argentina ended copper production in 2018. However, the country still holds sizable copper reserves. New projects could restore refined output over time. Meanwhile, Argentina is rising in global lithium. Production reached 18,000t in 2025, per USGS data. Approved Rigi projects span lithium, solar, LNG, oil, and steel. Therefore, midstream and mining investments are converging.

The Metalnomist Commentary

Rigi de-risks capex and timelines, which attracts major balance sheets. Yet execution still depends on permits, power, water, and offtakes. Watch EPC awards and community agreements to gauge bankability.

Argentinian Midterm Elections: A Pivotal Moment for Critical Minerals

Argentina midterm elections

Argentinian midterm elections are approaching. These elections will significantly shape President Javier Milei's economic reforms. Crucially, they will also influence key energy and mining plans. The outcome on October 26th is critical for the nation's future.

Milei's reforms began in December 2023. They successfully reduced annualized inflation to 31.8pc by September. The economy also expanded by 5.2pc. However, progress has recently slowed. Inflation remains above 2pc monthly. Growth in August was the slowest in almost a year.

The US Treasury offers a $40bn "bridge" package. This package supports the Argentinian peso. It includes a $20bn currency swap. A $20bn private capital facility is also part of the plan. International lenders pledged an additional $42bn in April. This support aims to stabilize Argentina's economy.

Energy Legislation and Investor Confidence at Stake

The election's results will impact legislative actions. Congress must decide on a new renewable energy law. The current law, 27191, expires this year. It mandated 20pc renewables by 2025. Renewables already hit 22pc in September. A new green hydrogen bill is also progressing.

Investor confidence in Argentina's energy ambitions is vital. The nation aims to be a major oil and gas exporter. It targets 1mn b/d of oil exports. LNG exports could reach 30mn tonnes/yr. These goals require over $50bn in investment. Therefore, the Argentinian midterm elections are crucial for these plans.

The Metalnomist Commentary

The upcoming Argentinian midterm elections hold immense implications for the global critical minerals and energy sectors. A strong mandate for Milei's reforms could unlock significant investment. This would accelerate Argentina's resource development. Conversely, a setback might introduce policy uncertainty. This could delay crucial projects. Therefore, industry stakeholders will closely monitor the results.

Japan Eyes Investments in Argentinian Lithium as Demand for Battery Metals Grows

Argentina lithium

Salta Province Attracts Japanese Interest Through RIGI and Strategic Bilateral Proposals

Japan eyes investments in Argentinian lithium to secure long-term access to key battery metals amid global electrification efforts. Japanese government officials recently met with authorities from Argentina’s Salta province to assess the region’s lithium reserves and explore opportunities for partnership. The talks focused on Salta’s lithium potential and included inquiries into major mining projects across multiple commodities—signaling broader strategic interest in Argentina’s resource sector.

Energy Transition Drives Argentina’s Copper Ambitions

Argentina aims to become a leading copper producer within the next decade, positioning itself as a critical player in the global energy transition. Although the country has not produced copper since 2018, a surge of new investments and policy reforms is transforming its mining landscape. The focus keyphrase, “Argentina copper production,” highlights the government’s strategic goal to leverage its vast mineral reserves.

Strategic Investments and RIGI Program Accelerate Growth

Argentina's mining secretary projects near-term copper output of 900,000 metric tonnes per year from seven advanced-stage projects, with potential to triple production if 15 additional ventures proceed. These seven projects alone could attract over $19 billion in investment. Much of the growth stems from the RIGI incentive program, launched by President Javier Milei's administration to encourage large-scale investments by offering tax breaks and legal certainty. As a result, international companies are showing renewed confidence in Argentina’s mining sector.

Vicuna Joint Venture Exemplifies Argentina’s Mining Revival

The Vicuna joint venture, formed by BHP and Lundin Mining, illustrates the impact of RIGI. It merges two major copper assets—Filo del Sol and Josemaria—which will produce a combined 200,000 tonnes annually. Vicuna’s total investment exceeds $5 billion, and the Filo del Sol discovery is hailed as the largest greenfield copper find in 30 years. Without the RIGI framework, stakeholders confirm this venture would not have materialized. Therefore, Argentina copper production is now seen as a viable and attractive avenue for global mining capital.

The Metalnomist Commentary

Argentina's copper strategy showcases how policy, resource endowment, and global demand can align to reshape a nation’s industrial future. If project timelines and regulatory stability hold, Argentina could challenge Peru and China as a copper heavyweight—making it a linchpin in energy-transition supply chains.

Argentina Salta Lithium Boom Positions Province as Global Energy Transition Hub

Argentina Salta Lithium

Argentina Salta lithium boom accelerates as the northern province emerges as the cornerstone of the country's expanding mining industry following government approval of Rio Tinto's Rincon project under the RIGI incentive program. The Argentina Salta lithium boom reflects strategic positioning within global energy transition supply chains, with provincial mining secretary Romina Sassarini declaring Salta will become "a reference point for lithium in the country and worldwide" as multiple international producers establish operations in the resource-rich region.

RIGI Program Attracts International Lithium Investment

Argentina Salta lithium boom benefits from the national government's RIGI economic and legal incentive program that provides fiscal and legal stability for major mining investments. Rio Tinto's newly approved Rincon mine represents the fourth lithium project in Salta, requiring $2.7 billion investment to produce 60,000 tonnes annually by decade's end. China's Ganfeng, France's Eramine, and South Korea's Posco already operate lithium production facilities while applying for RIGI incentives for expanded production stages.

Meanwhile, Argentina's lithium output surged from 75,000 tonnes in 2024 to projected 131,000 tonnes in 2025 according to mining trade organization CAEM. This rapid production growth positions Argentina as a critical supplier for global battery markets while establishing Salta as the primary production hub. The province's strategic importance extends beyond lithium to include copper and gold reserves, including First Quantum Minerals' $3.5 billion Taca Taca copper-gold-molybdenum project awaiting final permits.

Infrastructure Development Addresses Production Bottlenecks

However, massive infrastructure investments are required to support expanding mining operations and projected production growth. Mining projects operating and planned in Salta require additional 575MW of electricity generation capacity, prompting provincial development of comprehensive electricity plans emphasizing solar power deployment. The renewable energy focus aligns with sustainable mining practices while addressing power supply constraints.

Therefore, transportation infrastructure development becomes equally critical as the province pursues multilateral bank financing for the 2,400-kilometer bi-oceanic highway connecting Brazil to Chile through Argentina and Paraguay. This continental corridor will enable efficient lithium and mineral exports to Pacific and Atlantic markets while reducing logistics costs. Sassarini emphasized that coordinated efforts between provincial, company, and national government stakeholders will resolve logistic bottlenecks limiting industry growth.

Furthermore, Salta's emergence as a world-class lithium exporter addresses growing global demand for battery materials essential to electric vehicle production and energy storage systems. The province's integrated approach combining multiple international producers, infrastructure development, and regulatory stability creates competitive advantages for sustained industry growth. Mining sector transformation generates substantial economic impact through employment, tax revenue, and supply chain development.

As a result, the RIGI program eliminates financial bottlenecks while creating frameworks for long-term industry development across multiple mineral commodities. Salta's strategic positioning within the Lithium Triangle region enhances Argentina's competitiveness against Chilean and Bolivian producers while serving diverse global markets. The coordinated development approach demonstrates how provincial governments can catalyze mining industry growth through targeted policy support and infrastructure investment.

The Metalnomist Commentary

Argentina's Salta province exemplifies how strategic resource endowments combined with supportive policy frameworks can rapidly transform regional economies into global supply chain hubs, particularly important as lithium demand accelerates through energy transition requirements. The province's comprehensive approach addressing both production capacity and infrastructure bottlenecks demonstrates sophisticated understanding of mining industry development requirements, positioning Salta advantageously within the competitive global lithium market as established and emerging producers seek reliable supply sources.

Lundin Mining Eyes Argentina Incentives to Advance Vicuña Copper Project

Lundin Mining

Copper price rally offsets production dip as Lundin expands in South America

Lundin Mining Argentina copper incentives may become a key strategic lever for advancing its Vicuña project amid a global copper bull run. The company is evaluating Argentina’s Incentives Regime for Large Investments (RIGI), which offers tax relief, streamlined customs, and royalty reductions for large-scale projects.

Vicuña project gains traction under pro-investment Argentine policy

Lundin is bullish on Argentina’s current investment climate under President Javier Milei. The Vicuña project—located in the Andes and rich in copper, gold, and silver—is in pre-construction. If approved under RIGI, it would gain critical cost advantages and regulatory support, enhancing its competitiveness in the South American copper belt.

Profit soars despite Q1 output declines

Lundin’s Q1 2025 copper output declined 4% year-on-year to 77,000 tonnes, while shipments fell to 81,000 tonnes. However, surging copper prices—ranging between $4.43 and $4.63/lb—doubled the company’s net profit to $168 million. Nickel performance weakened, with output and sales down sharply from Q1 2024. Lundin remains focused on reaching 303,000–330,000 tonnes of copper output by year-end and recently divested its European zinc assets to Boliden for $1.4 billion.

The Metalnomist Commentary

Lundin’s pursuit of Argentine incentives reflects growing investor interest in copper projects outside traditional jurisdictions. With copper demand surging and Argentina offering favorable fiscal terms, the Vicuña project could emerge as a new anchor in Lundin’s Americas-focused strategy.

US Tariffs May Spur Argentina Lithium Salts Production

US Tariffs

Tariff Exemptions Favor Lithium Raw Materials, Not Finished Batteries

The US has exempted lithium carbonate and lithium hydroxide from its newly announced tariffs, creating a possible boon for Argentina's lithium sector. While raw lithium salts escape extra duties, finished battery imports face steep tariffs: 64.9% for China, 24% for Japan, and 25% for South Korea.

This disparity aligns with US efforts to localize battery manufacturing, a movement accelerated by the Inflation Reduction Act under President Biden. With at least 10 new battery factories coming online in the US this year, the demand for lithium raw materials is surging.

Argentina’s Brine Lithium May Fill the US Supply Gap

The US faces a bottleneck in domestic lithium production and processing. Currently, Albemarle’s Silver Peak mine is the only active operation, producing just 5,000t/yr of technical-grade lithium carbonate, which lacks the purity needed for EV batteries.

As a result, the US will increasingly depend on lithium imports, especially battery-grade salts. Argentina, with its low-cost brine operations, may become a preferred supplier if its projects can consistently meet battery-grade specifications.

Brine operations, while slower to ramp up than hard-rock mining, are cheaper to operate and typically more cost-competitive over time. Argentina also offers a low 3% royalty tax, compared to Chile's 40% ceiling, enhancing its competitiveness.

Global Lithium Supply Chains May Shift Toward South America

Countries like Australia and Brazil, which mine spodumene, rely heavily on China for conversion, placing them in a higher tariff category. These spodumene-dependent nations now face at least 20% US tariffs due to their reliance on Chinese refining infrastructure.

Meanwhile, Argentina’s direct-to-battery-grade production strategy may give it an edge.

“All of Argentina’s lithium projects go to battery grade,” said Daniel Gonzalez, Argentina’s vice-minister of energy and mining.

If Argentina proves its capability at scale, the country could secure a dominant role in North America's clean energy transition, especially as the US reorients trade relationships in critical minerals.

The Metalnomist Commentary

With tariffs redrawing global battery supply lines, Argentina’s brine-based lithium sector is now a strategic wildcard. If proven at scale, it could shift market share away from spodumene producers tied to China—and bring Latin America deeper into the heart of US industrial planning.
