Argentina Lithium Incentives Could Accelerate Pozuelos-Pastos Grandes Development

Pozuelos-Pastos Grandes

Argentina lithium incentives could support one of the country’s largest planned lithium brine developments as Ganfeng and Lithium Argentina apply for the Rigi large investment regime. The companies submitted the application after securing environmental permits for the Pozuelos-Pastos Grandes project.

The Pozuelos-Pastos Grandes project combines three brine assets under a 67-33pc joint venture between Ganfeng and Lithium Argentina. The partners plan to invest a combined $3bn to develop the operation into a major lithium carbonate equivalent producer.

Argentina lithium incentives are important because lithium projects require long development timelines, heavy infrastructure spending, and stable fiscal conditions. Rigi offers approved investors tax and royalty reductions, customs facilitation, accounting flexibility, and 30-year legal stability.

Pozuelos-Pastos Grandes Targets Large-Scale Lithium Carbonate Output

The Pozuelos-Pastos Grandes project is designed to produce 150,000 t/yr of lithium carbonate equivalent at full capacity. This would make it a major addition to Argentina’s lithium supply pipeline and strengthen the country’s position in the global battery materials chain.

The project will use a mix of evaporation and direct lithium extraction techniques. This hybrid approach reflects a broader industry trend, as developers seek to improve recovery, reduce processing bottlenecks, and manage water and environmental constraints more carefully.

Production is scheduled to start in 2029 at 25,000 t/yr. The operation is expected to reach 50,000 t/yr by 2031, then 100,000 t/yr by 2034, before ramping up to 150,000 t/yr by 2038 after two phased expansions.

Legal Stability Becomes Critical for Lithium Investment

Argentina lithium incentives could improve investor confidence at a time when lithium prices, financing conditions, and project costs remain challenging. Large brine projects need predictable rules because returns depend on multi-decade production and phased capital deployment.

The Rigi application also shows how Argentina is trying to convert its lithium resource base into industrial investment. Environmental permits give the project a regulatory foundation, while incentive approval could improve the commercial framework for construction and expansion.

For global battery supply chains, the project’s timing matters. If delivered as planned, Pozuelos-Pastos Grandes could add meaningful lithium carbonate equivalent supply during the 2030s, when EV, energy storage, and battery manufacturing demand may require more diversified sources outside current dominant supply channels.

The Metalnomist Commentary

Argentina’s lithium opportunity depends on whether policy stability can match geological potential. The Rigi framework gives projects like Pozuelos-Pastos Grandes a clearer investment case, but execution risk will remain high until financing, technology performance, and phased ramp-up are proven.

Lithium Argentina and Ganfeng to Develop Brine Lithium Projects

Ganfeng Lithium

New Agreement Targets Pozuelos-Pastos Grandes Basin Expansion

Lithium Argentina and Ganfeng Lithium signed a letter of intent to jointly develop lithium resources in Argentina’s Pozuelos-Pastos Grandes basin. The collaboration involves three projects: Pastos Grande, Sal de la Puna, and the Pozuelos project, all located in Salta province.

Ownership is split between the two firms across the assets. Lithium Argentina holds 85% of Pastos Grande and 65% of Sal de la Puna, while Ganfeng holds the remaining stakes.

The Pozuelos-Pastos Grandes project is fully owned by Ganfeng, but will be included in the partnership scope.

Ambitious Plans for Brine and DLE Operations

The new agreement provides a framework to finalize resource development through both traditional brine evaporation and direct lithium extraction (DLE) methods. When completed, the combined lithium projects are projected to yield 150,000 tonnes per year of lithium carbonate equivalent (LCE).

The parties may also expand production to include lithium chloride, providing downstream flexibility for battery material supply. This strategic cooperation adds scale and supply certainty amid global lithium demand fluctuations.

Cauchari-Olaroz Project Supports Growth Trajectory

The two companies also operate Argentina's leading lithium asset, the Cauchari-Olaroz project, via their joint venture Exar. This facility produced 25,400 tonnes of LCE in 2024, and aims for up to 37% output growth in 2025.

Together, the expanded brine portfolio and Exar’s performance underscore Argentina’s growing importance in global lithium supply chains.

The Metalnomist Commentary

As Western automakers seek secure lithium sources, Argentina’s brine projects are gaining strategic prominence. The Lithium Argentina–Ganfeng alliance could evolve into one of South America’s most influential LCE partnerships.

Ganfeng and LAR Argentina lithium project JV targets 150,000 t/yr LCE with DLE

Ganfeng lithium

Ganfeng and LAR Argentina lithium project JV will integrate three brine assets and deploy DLE at scale. The Ganfeng and LAR Argentina lithium project JV consolidates Pozuelos-Pastos Grandes, Pastos Grandes, and Sal de la Puna. As a result, the Ganfeng and LAR Argentina lithium project JV aims to build 150,000 t/yr LCE capacity in three phases.

JV structure, financing, and offtake

Ganfeng will control 67pc of Millennial, with LAR holding 33pc. The JV sits under LAR’s subsidiary, Millennial. Ganfeng will extend up to $130mn in financial assistance over six years. Meanwhile, LAR will supply an additional offtake equal to 6,000 t/yr LCE. That supply comes from LAR’s Phase 1 stake in Cauchari-Olaroz until Millennial ramps.

Technology, timeline signals, and regional significance

The JV will use direct lithium extraction to lift recovery and cut water intensity. However, the partners have not disclosed construction or start dates. Integration reduces duplication and accelerates project permitting. It also deepens Chinese–Western capital alignment in Argentina’s Lithium Triangle. Therefore, downstream buyers gain scale, diversification, and improved ESG narratives.

Millennial combines three brine projects into a single development path. Pozuelos-Pastos Grandes is fully owned by Ganfeng today. Pastos Grandes is 85pc LAR and 15pc Ganfeng. Sal de la Puna is 65pc LAR and 35pc Ganfeng. The new structure simplifies investment decisions for future phases.

Ganfeng’s operating base strengthens the JV’s execution. The company produced 130,253t LCE in 2024 across carbonate, hydroxide, chloride, and metal. It is ramping Cauchari-Olaroz toward 30,000–35,000t this year. That learning curve should de-risk Millennial’s early phases. In turn, battery-grade carbonate supply should scale faster.

The Metalnomist Commentary

Consolidation plus DLE is the right playbook in Argentina. Offtake pre-commitments bridge financing while Cauchari-Olaroz provides near-term cover. Watch for phased EPC awards, brine handling contracts, and pond-to-DLE hybrid designs as leading indicators.

Lithium Argentina Cauchari-Olaroz expansion moves ahead despite 3Q loss

Cauchari-Olaroz

Lithium Argentina Cauchari-Olaroz expansion remains firmly on track even as the company posts a 3Q net loss. The flagship brine project delivered 8,300t LCE in the quarter and keeps guidance of around 32,000t for 2025. However, currency impacts and legacy financing costs pushed Lithium Argentina to a $64.5mn loss, underlining the financial volatility around the Cauchari-Olaroz expansion.

Strong production, weak pricing pressure margins

Cauchari-Olaroz remains one of Argentina’s largest single lithium projects and is running at about 80pc of capacity. The project has produced 24,000t LCE over January-September, 22pc higher than a year earlier, confirming the operational strength behind the Lithium Argentina Cauchari-Olaroz expansion. However, average realized prices of $7,522/t for lithium carbonate limit cash flow compared with the 2022 price peak.

Lithium Argentina holds a 44.8pc economic interest in the project via its Minera Exar joint venture with Ganfeng Lithium. As a result, its attributable revenue from Cauchari-Olaroz reached only about $26.4mn in the third quarter. Currency fluctuations and the conversion of earlier loans to Minera Exar into equity added more than $78mn in accounting losses, overshadowing solid operating metrics from the Cauchari-Olaroz expansion.

Rigi incentives key for PPG and next growth wave

The company’s growth strategy now hinges on securing Argentina’s Rigi incentives for large investments. LAR and Ganfeng plan to use the regime to support both the Lithium Argentina Cauchari-Olaroz expansion and the much larger Pozuelos-Pastos Grandes (PPG) cluster. PPG could reach 150,000t/yr LCE at full ramp-up, making it one of the biggest planned lithium brine platforms in the country.

The Rigi framework offers reduced taxes and royalties, streamlined customs, accounting flexibility and 40-year legal stability. Therefore, successful approval would materially improve project economics and risk perception for lenders and strategic offtakers. LAR aims to file a Rigi application for PPG in the first half of 2026, while a separate Rigi process for the Cauchari-Olaroz expansion is also in preparation.

The Metalnomist Commentary

Lithium Argentina is demonstrating that scale and uptime at Cauchari-Olaroz can offset some of the pain from lower prices and FX swings. The crucial question is how quickly Rigi incentives are granted, because these terms will shape funding costs for both Cauchari-Olaroz and PPG. For investors and cathode buyers, Argentina’s policy execution will help determine whether this emerging lithium hub meets its aggressive capacity targets.

Argentina lithium production capacity set to surge 250pc by 2035

Argentina lithium

Argentina lithium production capacity is entering a new expansion phase that will reshape global battery raw material supply. The government now targets a more than 250pc increase in Argentina lithium production capacity over the next decade, after capacity has already more than doubled in the past two years. This rapid scale-up positions the country as a central pillar of the lithium triangle and a strategic partner for global battery and EV manufacturers seeking long-term supply security.

Rapid build-out of Argentina lithium production capacity

Argentina lithium production capacity has grown from 75,500 t/yr in 2023 to 186,000 t/yr of LCE in 2025. This represents a 146pc increase and marks a sharp acceleration from 2015, when just 35,000 t/yr came from two active projects. Today there are seven operating projects across multiple salars, backed by a mix of global and regional producers. These assets include operations linked to Rio Tinto, Posco, Ganfeng, Lithium Argentina, Zijin and a Franco-Chinese joint venture, reflecting diversified ownership and financing structures.

By 2030, Argentina lithium production capacity is expected to reach 418,000 t/yr and then rise to 658,000 t/yr by 2035. This trajectory implies a potential 253pc increase versus 2025 levels as brownfield expansions and new projects ramp up. Authorities built their outlook on 15 projects, combining the seven operating sites, their planned expansions and eight advanced developments such as Hombre Muerto West, Pozuelos-Pastos Grandes, new carbonate units and brine projects in the pipeline. As a result, Argentina is moving from a niche supplier to a core pillar of global LCE growth.

Strategic implications for global lithium supply chains

This expansion of Argentina lithium production capacity comes as automakers and battery producers seek diversified supply beyond a few dominant jurisdictions. Additional Argentine brine output should help ease medium-term supply risk, even as demand from EVs, energy storage and grid applications continues to grow. However, timing risks remain around permitting, infrastructure, community engagement and financing, which could still shift the actual ramp-up profile.

For investors, the enlarged project pipeline offers exposure across different risk and return profiles, from established brine operations to newer developments led by mid-tier players. Meanwhile, downstream buyers are likely to pursue more long-term offtake agreements in Argentina to lock in volumes and hedge against price volatility. Over time, the country’s growing role in the lithium triangle may also support the emergence of local value-added industries, such as cathode materials or battery component production, if policy and infrastructure align.

The Metalnomist Commentary

Argentina’s push to expand lithium production capacity confirms that supply growth will not be constrained to one or two regions. The key question is not whether capacity is planned, but how much of it will arrive on time and on budget. For now, Argentina looks set to climb rapidly up the league table of LCE producers, but execution risks, water management and community dynamics will ultimately determine how much of this theoretical capacity becomes reliable, long-term supply.
