Rock Tech Lithium: Building an Integrated Lithium Supply Chain for the Battery Age

Market Focus

Rock Tech Lithium is a Canadian mine to refinery lithium company focused on producing battery grade lithium hydroxide and establishing a closed loop supply chain for electric vehicles and energy storage. The company owns 100 percent of its flagship hard rock lithium asset, the Georgia Lake Project, located in the Thunder Bay mining district of Ontario, and is developing downstream conversion capacity in both Europe and North America.

Platform and Strategy

Rock Tech’s strategy is anchored in three core pillars:

• Develop the Georgia Lake Project as a reliable, high quality spodumene feedstock for the company’s downstream refineries.

• Construct lithium converters close to end markets, beginning with the Guben Converter in Brandenburg, Germany, designed for an annual capacity of approximately 24,000 tonnes of battery grade lithium hydroxide, followed by a planned facility in Red Rock, Ontario.

• Embed sustainability, recycling, and closed loop supply principles to position the company as a leading, environmentally responsible lithium supplier.

Recent Progress and Growth

• The Guben Converter in Germany has been designated a Strategic Project under the European Union Critical Raw Materials Act, providing regulatory visibility and potential access to strategic funding.

• Engineering and permitting work for Guben continue to advance, with site preparation and financing discussions underway to move the project toward construction readiness.

• In Canada, Rock Tech is progressing technical and site assessment work for the Red Rock Converter, which will complement Georgia Lake and anchor a vertically integrated lithium production hub in Ontario.

• The company continues to optimize its Georgia Lake resource, refine its process flowsheet, and strengthen its European partnerships for long term offtake and processing collaboration.

Partnerships and Strategic Positioning

Rock Tech is strategically positioned at the intersection of mining, refining, and battery materials supply for electric vehicles. Its dual continent model, with upstream mining in Canada and downstream refining in Europe, provides both geographical diversification and proximity to major battery manufacturing hubs. The company’s focus on sustainability, regulatory alignment, and end market integration supports its goal of being one of the first integrated lithium producers serving the European and North American supply chains.

Leadership and Capital Markets Strategy

Rock Tech Lithium is led by Chief Executive Officer Mirco Wojnarowicz and Executive Chairman Dirk Harbecke. The leadership team brings strong expertise in lithium processing, project development, and capital markets. The company remains committed to disciplined execution, transparent communication, and long term value creation through project delivery and partnerships.

Near Term Catalysts

• Completion of project financing and permitting milestones for the Guben Converter.

• Continued development and technical de risking of the Red Rock Converter in Ontario.

• Additional offtake and partnership announcements with European battery manufacturers and cathode producers.

• Further resource expansion and metallurgical optimization at the Georgia Lake Project.

• Advancements in recycling initiatives to close the loop in the lithium value chain.

Conclusion

Rock Tech Lithium enters late 2025 with an integrated development platform spanning mining, refining, and recycling. With flagship projects in Ontario and Germany, strategic partnerships across the battery materials ecosystem, and alignment with global electrification and critical minerals priorities, Rock Tech is positioned to become a key supplier of sustainable battery grade lithium hydroxide to the growing electric vehicle and energy storage markets.
