TORONTO , June 11, 2025 /CNW/ - Rock Tech Lithium Inc. (TSXV: RCK) (OTCQX: RCKTF) (FSE: RJIB) (the "Company" or "Rock Tech") is pleased to announce that it has been selected for funding under the prestigious KAVA (Knowledge and Innovation Activities) grant program by EIT RawMaterials, the most active network in the raw materials sector in Europe. This recognition supports Rock Tech's ongoing commitment to advancing innovative lithium refining solutions in Europe and is the first funding awarded after Rock Tech's Lithium Hydroxide Convertor Guben (LHCG) project has been recognized as a strategic project under Critical Raw Materials Project by the European Commission. Rock Tech will receive EUR 800,000 to improve and innovate its lithium conversion process to be applied to its Guben Converter in the future.

Under the KAVA Call-funding program, Rock Tech's Lithium subsidiary company Rock Tech Guben GmbH will collaborate with leading research and industry partners, including NTUA (Greece), VITO (Belgium), and Admiris (Greece), to optimize lithium extraction processes and enhance lithium hydroxide monohydrate (LHM) production from spodumene. Rock Tech believes this optimization work will create substantial future operational and cost benefits for the Guben Converter.

"We are honored to be selected for the KAVA Call funding and to work jointly with partners to commercialize innovative, potentially game-changing lithium processing technologies", comments Mirco Wojnarowicz, Rock Tech's CEO.

The selected project, named OLiVer (Hard rock Lithium Extraction and Purified Value Products for Energy Applications) will demonstrate innovative processes at pilot scale, significantly improving lithium recovery efficiency and reducing environmental impact in line with EU green transition goals. The OLiVer project will focus on four main objectives:

1. Optimizing pyro-hydro-metallurgical processing to enhance lithium extraction efficiency from spodumene.
2. Developing a novel secondary lithium sulfate recovery process, enabling improved lithium recovery rates.
3. Integrating primary and secondary lithium sulfate streams to boost overall LHM production yield.
4. Conducting pilot-scale demonstrations to establish commercial viability for the enhanced lithium extraction process.

With this project, Rock Tech aims to drive forward the EU's critical raw materials strategy and sustainability goals by producing high-purity LHM for electric vehicle batteries regionally.

ABOUT ROCK TECH 

Rock Tech's vision is to supply the electric vehicle and battery industry with sustainable, locally produced Lithium, targeting a 100% 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, Ontario, 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 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.
