Rio Tinto keeps Serbia’s Jadar lithium project in reserve as it stays in care and maintenance

Serbia’s controversial Jadar lithium project is increasingly being framed by industry observers not as a cancelled investment, but as an asset paused for the long term. Rio Tinto’s continued engagement—despite the project’s current pause phase—signals that the company remains committed to the deposit while key conditions are expected to evolve.

A strategic pause, not an exit

Jadar officially moved into care and maintenance in 2025. However, observers say this designation functions more like a strategic holding pattern than an abandonment of plans. Rio Tinto has maintained its legal presence and core operational footprint in Serbia, preserving rights over what is widely described as one of Europe’s most significant undeveloped lithium resources.

Political uncertainty has added to the complexity, but the company’s ongoing involvement suggests Jadar has not been removed from its longer-term development pipeline. Instead, the project is being kept in readiness while regulatory and social conditions shift.

The central bottleneck remains environmental approval. Any restart depends heavily on the completion and acceptance of the Environmental Impact Assessment (EIA), which would determine whether development can proceed in a formal capacity.

One of Europe’s largest lithium deposits

The Jadar basin hosts a rare lithium-boron mineral system that is geologically distinct from many other global lithium projects. Estimated resources cited for Jadar include around 118 million tonnes of ore and potential annual output of approximately 58,000 tonnes of lithium carbonate. If developed at full scale, the project could become among the world’s most important producers of battery-grade lithium used in electric vehicles and energy storage systems—an outcome that helps explain why it continues to attract strong geopolitical attention across Europe.

Why it matters for Europe’s supply chain

European policymakers have repeatedly identified Jadar as a critical lever for reducing dependence on imported lithium, particularly as demand for EV batteries accelerates across the continent. If operational, it could strengthen Europe’s domestic supply chain, reduce reliance on external producers, support expansion in automotive and battery manufacturing, and improve regional supply security for technology and clean-energy industries.

For the EU, Jadar is positioned not only as a mining project but also as part of a broader effort to secure critical raw materials independence.

Environmental opposition remains a defining factor

Despite its strategic importance, Jadar remains one of Europe’s most contested mining projects. Environmental groups, local communities, and academic voices continue to raise concerns including water usage and groundwater risks, land degradation and ecosystem impacts, and issues related to chemical processing and waste management.

Public opposition previously contributed to permits being revoked in 2022. While later legal decisions reopened development possibilities, resistance has continued to shape expectations for timing. Some assessments argue that execution under current conditions would remain highly challenging due to both technical complexity and social sensitivity.

There are also ongoing debates about how economic benefits would be distributed. Critics contend that Serbia may receive relatively limited fiscal upside compared with the scale of investment required—an argument that continues to influence public perception and adds another layer of uncertainty around any potential restart.

Wait-and-adjust strategy amid financing realities

Rather than exiting Serbia, Rio Tinto appears to be pursuing a wait-and-adjust approach: keeping Jadar available while monitoring developments such as EU critical raw materials policy changes, lithium market pricing and demand cycles, regulatory clarity in Serbia, and public acceptance alongside permitting conditions.

The project is also described as capital intensive, with estimated capital costs exceeding €2.5–3 billion. Projects at this scale typically face long development timelines that can include repeated redesigns, environmental reassessments, and extended financing windows—challenges that can be amplified where public scrutiny is high.

Still embedded in Europe’s long-term lithium planning

Even with its suspended status, Jadar remains embedded in Europe’s longer-term industrial planning due to its large-scale resources, strategic location within Europe, corporate backing, and growing demand for battery materials. Together, these factors keep it central to discussions about Europe’s raw materials security and energy transition strategy.
