Statement by the CEO of Rock Tech Lithium on the ResourceEU Plan

The latest news release, dated 2025-12-03, is a statement by Rock Tech Lithium Inc.'s CEO, Mirco Wojnarowicz, regarding the EU's recently unveiled ResourceEU Action Plan. The CEO positions Rock Tech's Guben Lithium Converter project in Germany as a strategic, near-term contributor to European lithium supply. He highlights that the project is listed as an EU strategic raw materials project, has permits in place, strategic offtakers ready, and established technology with clear ESG standards. Wojnarowicz states that the company can "quickly deliver a substantial contribution to European supply." He also emphasizes that recent revisions of cost structures (referring to previously announced operating and capital expenditure reductions) have laid an "important foundation for the final investment decision (FID)." The CEO concludes that the ResourceEU Plan brings unprecedented clarity regarding financing, coordination, and political will, and the company stands ready to build lithium value creation in Europe.

This news is a positive reaffirmation of Rock Tech's strategic direction and the Guben project's position within Europe's critical raw materials strategy. However, it does not announce new material information or a specific corporate action. Instead, the CEO is leveraging the new EU policy to highlight the company's existing progress and strategic advantages, such as: * EU Strategic Project Status: The Guben converter was designated a "Strategic Project" under the EU Critical Raw Materials Act in March 2025, which was a material positive event. The CEO's statement reiterates this existing advantage. * Cost Structure Revisions: The news explicitly references the "revision of our cost structures." This relates directly to the materially positive announcements in September 2025 (23% opex reduction, €27.7M annually) and October 2025 (€50M capex reduction, 6.9% reduction from €730M to €680M). These reductions significantly improved the project's economics and financing case, and the CEO is correctly framing them as foundational for the FID. * Offtakers and Financing: The mention of "strategic offtakers are ready" likely refers to the MOU with Ronbay Technology signed in June 2025. The "financing" and "political will" mentioned relate to the previously announced letters of support for €150M from UKEF and Finnvera, and potential €150M from the European Investment Bank (EIB) in May 2025, as well as the benefits derived from the CRMA strategic project status.

The statement is a positive endorsement from the CEO, reinforcing previously announced positive developments and positioning the company favorably in the context of broader European policy. It aims to generate confidence among stakeholders by aligning Rock Tech's progress with the EU's strategic goals for raw material independence. While positive, it does not introduce new information that materially alters the company's financial or operational outlook beyond what was already known from the recent material news releases regarding cost reductions, strategic project status, and financing expressions of interest.

Rock Tech Lithium Inc. is a Canadian critical minerals company focused on becoming a key supplier for the European and North American battery value chains. The company aims to achieve this through an integrated strategy encompassing mineral resource development and downstream processing.

Flagship Project: The Guben Lithium Converter in Brandenburg, Germany, is Rock Tech's flagship project. - Capacity: Designed to produce 24,000 tonnes of battery-grade lithium hydroxide monohydrate (LHM) per year. This capacity is estimated to be sufficient for approximately 500,000 electric vehicles annually. - Strategic Importance: The project is recognized as a "Strategic Project" under the European Commission's Critical Raw Materials Act (CRMA), highlighting its significance for securing Europe's supply of critical raw materials and fostering industrial autonomy in the battery sector. It is the only spodumene-to-LHM facility to receive this designation. - Development Stage: The project is currently in the final financing phase, with environmental and operating permits, as well as engineering studies, completed. Construction is contingent on a Final Investment Decision (FID). - Key Partnerships: - Technology Provider: GEA Group AG (crystallization and zero-liquid discharge technology). - EPCM Partner: Worley Ltd. - Feedstock Strategy: Initially secured spodumene concentrate from contracted partners (e.g., C&D Logistics Qingdao Co. Ltd.). Long-term plans include using lithium sulphate feedstock from the potential Lopare project. - By-product Utilization: Memorandum of Understanding (MOU) with Schwenk Zement GmbH & Co. KG to utilize leach residues as cement additives, reducing operational costs by ~7% (€6.3M annually) and improving environmental footprint. - Energy Supply: MOU with Enertrag SE for long-term supply of renewable energy from new wind and photovoltaic plants, aiming for at least 50% renewable electricity from 2030 and reducing CO2 emissions. - Offtake: MOU with Ronbay Technology Co. Ltd. (a global leader in cathode active materials) for long-term supply of LHM from Guben to Ronbay's European facilities. Ronbay also offered technical and potential investment support.

Other Projects: - Georgia Lake Project (Ontario, Canada): A lithium spodumene exploration and evaluation asset. The project is subject to a 1.5% Net Smelter Return (NSR) Royalty. The company received funding from Ontario's Critical Minerals Innovation Fund to develop an ore-sorting process for low-grade spodumene ores at this site. - Lopare Lithium Project (Bosnia-Herzegovina): This lithium-boron-magnesium mining project is part of a proposed business combination with Arcore AG. It holds an estimated JORC 2012 compliant resource of 600,000 tonnes Lithium Carbonate Equivalent (LCE). However, as per a July 2025 clarification, this historical estimate is not compliant with NI 43-101 standards, and a Qualified Person has not done sufficient work to classify it as current mineral resources under Canadian regulations. The transaction remains subject to multiple closing conditions and a €50M financing for the new joint venture.
