French mining group Eramet is developing the Centenario-Ratones lithium project in Argentina as part of Europe’s efforts to secure access to critical battery materials. The project is positioned as an advanced example of European-controlled lithium production outside Asia’s dominant processing networks. It combines large-scale production potential, direct extraction technology, and full European ownership.
In October 2024, Eramet completed its acquisition of Tsingshan’s 49.9% stake in Eramine Sudamerica. The transaction secures 100% ownership of the Centenario lithium project. Eramet reported a $699 million adjustment to net debt associated with the deal.
Direct lithium extraction capacity and resource base
The Centenario project is based on direct lithium extraction (DLE) technology and is designed for long-term output. Initial production capacity is stated at 24,000 tonnes per year of lithium carbonate equivalent (LCE). The project also has expansion potential exceeding 75,000 tonnes LCE annually.
Eramet estimates a total resource base of more than 15 million tonnes LCE. The scale of the resource places Centenario among the more significant lithium assets under European control. The project is described as providing exposure to a material that remains heavily processed in Asia, where much of the world’s lithium refining capacity is concentrated.
Role in battery raw materials supply chain
Centenario is presented as a component of Europe’s evolving battery raw materials strategy. As European automakers and battery manufacturers expand electric vehicle and energy storage system production, stable access to lithium is highlighted as increasingly important. Much of the global supply chain for lithium chemicals is described as controlled by established Asian processors, particularly in China.
The project is said to offer European ownership of upstream lithium production and access to South American brine resources in the “Lithium Triangle.” It also includes potential alignment with European battery manufacturing demand. This combination is framed around improving sourcing diversity and reducing supply-chain vulnerability.
Lithium market conditions and investment screening
The source material describes a shift in the lithium investment cycle following the 2021–2022 price boom. During that period, capital flowed into nearly every lithium project on expectations of sustained electric vehicle-driven demand growth. Since then, prices have corrected sharply from their peaks.
Investors are described as becoming more selective, with lithium projects needing to demonstrate strong cost control, proven extraction technology, secure financing structures, realistic development timelines, and clear commercial pathways. Under these conditions, strategic importance alone is stated as insufficient to attract capital.
Ownership decision during weaker prices and key risks
Eramet’s decision to fully acquire its Argentine lithium asset is described as occurring during a period of weaker lithium prices. The company increased control over production strategy, expansion timing, and future offtake decisions rather than reducing exposure. The source also links the project’s development environment to Argentina’s supportive approach to lithium investment in regions seeking long-term industrial partnerships.
The Centenario project faces structural risks common to large-scale lithium developments. These include currency and macroeconomic volatility in Argentina, evolving provincial tax and regulatory frameworks, water usage constraints in arid regions, fluctuating lithium carbonate prices, and differences in battery chemistry demand between carbonate and hydroxide. Long-term expansion decisions are stated to require alignment with global market conditions.
External supply anchor outlook through 2030
The source expects Centenario to become one of Europe’s most important external lithium supply anchors by 2026–2030. It is described as not eliminating Europe’s reliance on global markets but providing controlled exposure outside China-dominated processing chains. This positioning supports a broader strategy to diversify critical mineral supply chains for lithium, nickel, and other battery-related raw materials.
The material also describes a shift in how Europe engages with global resource development. Instead of relying on many small speculative ventures, it suggests an approach based on a limited number of well-capitalized anchor companies able to operate across jurisdictions. In this context, Eramet is cited as one of the few European mining groups with financial strength, operational experience, and an international footprint for managing large-scale strategic assets abroad.
Industrial control considerations for strategic minerals
The Centenario lithium project is described as more than a production asset and as a test related to industrial control. The source lists objectives including owning and operating strategic mineral resources abroad, maintaining control over value creation in critical supply chains, reducing dependency on dominant global processors, and integrating external mining assets into domestic industrial ecosystems.
If successful, the project could serve as a blueprint for securing future supplies of critical raw materials without losing control of the value chain. The source characterizes this as a strategic experiment in industrial sovereignty tied specifically to the Centenario development.
