Rock Tech Lithium and Arcore AG Are Reshaping Europe’s Battery Future

Lithium Independence: A Bold Move to Secure Europe’s Future

In a deal that could redefine Europe's lithium supply chain, Rock Tech Lithium Inc. and Arcore AG have announced a merger of their subsidiaries to form a fully integrated European lithium company. This strategic business combination will establish a joint venture controlling Rock Tech’s Guben Converter in Germany and Arcore’s Lopare lithium project in Bosnia-Herzegovina.

With lithium demand in Europe projected to triple by 2030, this move aims to build a self-sufficient and sustainable lithium value chain—crucial for the continent's electric vehicle industry and energy transition plans.

Europe’s Push for Lithium Independence: Ending the Import Reliance

The new entity—tentatively referred to as NewCo—will consolidate upstream mining assets and downstream lithium refining capabilities, addressing Europe’s overreliance on lithium imports. Currently, a significant portion of Europe’s lithium is sourced from regions such as China and Australia, exposing manufacturers to supply chain disruptions and geopolitical risks.

Under the terms of the agreement:

  • Rock Tech will hold a 75% stake in the new company, contributing its fully permitted lithium hydroxide converter in Guben, Germany.
  • Arcore will retain 25% ownership, bringing its Lopare lithium-boron-magnesium deposit, a resource with an estimated **600,000 tonnes of lithium carbonate equivalent **.
  • The merger will facilitate the on-site processing of lithium sulfate feedstock from Bosnia to Germany, reducing costs and enhancing supply chain security.

From Raw Material to Battery Power: The Game-Changing Integration

Guben Lithium Converter: A Near-Operational Refinery That Changes the Game

The Guben Converter, located in Germany’s Brandenburg battery cluster, is in its final financing phase and has already secured the necessary construction, environmental, and operational permits. Once operational, it is expected to supply battery-grade lithium hydroxide to power up to 500,000 EVs annually.

This refinery stands out for its potential to integrate recycled lithium—aligning with Europe’s circular economy goals. Engineering firm Worley Ltd. has been appointed as the EPCM provider, ensuring the facility meets global efficiency and environmental standards.

Lopare Lithium Project: Unlocking a Hidden European Powerhouse

The Lopare lithium project in Bosnia-Herzegovina is one of Europe’s largest lithium deposits, boasting 426 million tonnes of indicated resources and 864 million tonnes of inferred resources. However, while the mine is expected to deliver lithium sulfate feedstock to Guben, production isn’t projected to start until 2030—a potential bottleneck in the short term.

The project’s long-term value, however, is undeniable. Arcore has emphasized its commitment to responsible mining practices, seeking certification under the **Initiative for Responsible Mining Assurance ** to meet Europe’s stringent environmental, social, and governance requirements.

Investor Impact: The Future of Europe’s Lithium Market

Why This Deal Changes Everything for Europe’s Battery Industry

This merger aligns with the European Union’s push for supply chain sovereignty under policies like the Critical Raw Materials Act and the European Battery Alliance. By integrating mining and refining within the region, the joint venture will:

  • Reduce reliance on Chinese lithium processing, a key concern amid growing trade tensions.
  • Lower production costs through supply chain efficiencies and direct on-site lithium processing.
  • Enhance Europe’s competitiveness in the global battery industry, crucial for companies like Volkswagen, Stellantis, and Mercedes-Benz, which are aggressively scaling EV production.

Potential Hurdles That Could Disrupt the Lithium Revolution

While the merger presents numerous opportunities, several challenges remain:

  • Time Lag in Integration: The Lopare project won’t supply feedstock until 2030, meaning that in the short term, Rock Tech will still rely on spodumene feedstock from external suppliers.
  • Regulatory Uncertainty: While Germany has streamlined permitting for battery-related projects, Bosnia-Herzegovina’s mining concession approvals remain pending, creating potential delays.
  • Execution Risks: Coordinating operations across two different legal and industrial frameworks will require careful planning to avoid cost overruns and integration challenges.

Will This Deal Reshape the Lithium Market? The Road Ahead

The European lithium market is currently experiencing price volatility, driven by global supply fluctuations. While this merger won’t immediately alter lithium prices, it sets the stage for long-term price stability in the European market.

Investor Takeaways: What to Expect in the Coming Years

  • Long-Term Growth Potential: The joint venture has the potential to reshape the European lithium industry, but the full benefits won’t be realized until after 2030.
  • Strategic Policy Alignment: Given Europe’s aggressive push for battery independence, this deal is likely to receive regulatory support and potential subsidies.
  • Short-Term Volatility: Investors should expect near-term fluctuations as feedstock integration and permitting hurdles play out.

A Bold Vision: Europe’s Path to Lithium Self-Sufficiency

The Rock Tech-Arcore merger represents a bold step toward a European-controlled lithium supply chain, aligning with broader geopolitical and industrial policy goals. While short-term integration challenges remain, the long-term outlook positions this joint venture as a cornerstone of Europe’s battery ecosystem.

For automakers, policymakers, and investors alike, this merger underscores a shift in global lithium dynamics, with Europe no longer content to depend on external suppliers. Whether the project meets its ambitious timelines will determine its true impact on Europe’s EV revolution.
