ROCK TECH RECEIVES EUR 150 MILLION IN LETTERS OF SUPPORT FOR GUBEN CONVERTER

Rock Tech Lithium Inc. has received up to 150 million euros in government-backed support from export credit agencies via conditional, non-binding expressions of interest. Specifically, U.K. Export Finance (UKEF) and the Finnish export credit agency (Finnvera) have expressed their interest to support the Guben converter. In addition, discussions with further export credit agencies from Europe, Australia and China are continuing, to support the procurement of key equipment items from these countries. ECA support will be additional to the proposed European Investment Banks's (EIB) senior debt tranche of 150 million euros (as announced by the company in a previous press release).

"We welcome the strong backing from export credit agencies in supporting the Guben converter project. Their engagement reflects confidence in our vision, the business case and the strategic importance of this facility for Europe's green-energy transition," said Chris Wright, Rock Tech's chief financial officer.

In detail, the debt financing will benefit from the project's European sourcing scheme, making the project eligible for credit guarantees from major European export credit agencies. Large packages for supplies and services are to be contracted with business and procurement partners based in the United Kingdom and Finland, and other European Union countries. Subject to the due diligence being completed concurrently in accordance with their policies and applicable OECD (Organisation for Economic Co-operation and Development) consensus guidelines by the lending consortium and the ECAs, UKEF and Finnvera have expressed their initial interest in supporting the project via guarantees toward the lenders.

About the Guben converter

The Guben lithium converter is a pioneering facility in Guben, Brandenburg, Germany, by German-Canadian company Rock Tech Lithium. This plant is set to become Europe's first commercial lithium hydroxide refinery, aiming to produce 24,000 tonnes of battery-grade lithium hydroxide annually -— enough to supply over 500,000 electric vehicles per year.

Strategically located near major automotive and battery manufacturing hubs, the Guben converter is designed to strengthen Europe's battery supply chain by processing spodumene concentrate secured via leading trading partner C&D Logistics (Qingdao) Co. Ltd. The converter will utilize advanced crystallization technologies, supplied by GEA Group AG, to ensure high-purity lithium production with minimal environmental impact. Leading international engineering firm Worley Ltd. has been selected as construction partner (engineering, procurement and construction management) for the plant.

Recognized as a strategic project under the EU's Critical Raw Materials Act, the Guben converter underscores Europe's commitment to securing essential materials for the energy transition. The project is expected to create approximately 200 jobs and represents a significant step toward regionalizing and decarbonizing the lithium supply chain in Europe.

About Rock Tech Lithium Inc.

Rock Tech's vision is to supply the electric vehicle and battery industry with sustainable, locally produced lithium, targeting a 100-per-cent recycling rate. To ensure resilient supply chains, the company plans to build lithium converters at the doorstep of its customers, beginning with the company's proposed lithium hydroxide converter in Guben, Brandenburg, Germany. The second converter is planned to be built in Red Rock, Ont., Canada. Rock Tech Lithium plans to source raw material from its own Georgia Lake spodumene project in the Thunder Bay mining district of Ontario, Canada, and procure from other ESG-compliant (environmental, social and governance) mines. Ultimately, Rock Tech's goal is to create a closed-loop lithium production system. Rock Tech has gathered one of the strongest teams in the industry to close the most pressing gap in the clean mobility story. The company has adopted strict environmental, social and governance standards and is developing a proprietary refining process to increase efficiency and sustainability further.
