Rock Tech Lithium Provides Updates on Lopare Lithium Project and Arcore Transaction

Toronto, July 7, 2025 - Rock Tech Lithium Inc., a prominent player in the lithium industry, has issued a crucial update regarding the Lopare Lithium Project, in other developments pertaining to its strategic transaction with Arcore AG. This announcement comes after a thorough evaluation by the Ontario Securities Commission, aiming to clarify prior disclosures related to mineral resources associated with the Lopare Lithium Project.

Historical Estimates and Technical Disclosures

Rock Tech asserts that the mineral resource estimate previously disclosed for Arcore's Lopare project was regarded as a “historical estimate” under the National Instrument 43-101 (NI 43-101) standards. The source of this estimate is a comprehensive report produced for Arcore by CSA Global Pty Ltd., an independent mining consultancy. The report, effective as of November 30, 2022, was not prepared in line with NI 43-101 standards and is currently unavailable for public review.

The historical estimate highlights the project's considerable lithium and boron resource potential, drawn from a dataset based on 14,035 assay sample results from 69 historical drill holes. However, Rock Tech cautions stakeholders that this assessment did not conform to the CIM Definition Standards for Mineral Resources and Mineral Reserves. Therefore, it cannot be classified as current mineral resources until adequate technical work supports such a classification.

When conducting this estimate, CSA Global adopted a block model method with grade estimation via inverse distance weighting squared (IDW²), factoring in lithium carbonate and boric oxide price projections. Importantly, while promising, this estimate requires verification through essential field exploration and diamond drilling programs, aimed at confirming existing geological data.

Strategic Update on the Arcore Transaction

Following the announcement on February 20, 2025, Rock Tech is focused on the strategic transaction with Arcore to forge a fully integrated European lithium entity. The synergy would unite Rock Tech's Guben Converter in Germany with Arcore's Lopare Lithium Project, advancing their mutual goal of sustainable lithium production.

Key outstanding conditions for this transaction include:

• - Technical and Legal Due Diligence
• - Board and Shareholder Approvals
• - Regulatory Approvals, including TSX Venture Exchange authorization
• - A €50 Million Financing Strategy
• - Definitive Agreements

Rock Tech emphasizes that completion of this transaction is contingent upon meeting all requisite closing conditions, including regulatory permissions and adequate financial backing of at least €50 million.

Future Direction and Vision

Rock Tech's overarching vision is to become a leading supplier of sustainable lithium for the electric vehicle and battery industry, targeting 100% recycling rates. The company aims to establish manufacturing operations close to its customers to ensure resilient supply chains, with a lithium hydroxide converter projected for Guben, Germany, and plans for a second one in Ontario, Canada. The company's sourcing strategy includes materials from its Georgia Lake project and other ESG-compliant suppliers.

Rock Tech has assembled an experienced team committed to filling existing gaps in clean mobility solutions while adhering to strict environmental, social, and governance standards. Their focus also includes developing proprietary refining processes to enhance efficiency and sustainability.

As Rock Tech navigates these complexities in the lithium sector, it remains committed to transparency and fulfilling its responsibilities towards its stakeholders and the environment. Any forward-looking statements within this release are made with caution, as they depend on multiple conditions and market dynamics, all of which could influence outcomes considerably.

Conclusion

In summary, Rock Tech Lithium is making significant strides towards validating and advancing the Lopare Lithium Project while strategically progressing in its partnership with Arcore. By solidifying the necessary groundwork, the company is taking crucial steps to guarantee its place in the evolving landscape of the lithium supply chain.
