ROCK TECH LITHIUM AND BMI GROUP ESTABLISH CAD $200 MILLION ANCHOR PARTNERSHIP TO ADVANCE RED ROCK LITHIUM CONVERTER IN CANADA

Rock Tech Lithium Inc. has formed a strategic partnership with the BMI Group Inc., a Canadian industrial infrastructure platform company, to develop Rock Tech's lithium converter facility in Red Rock, Ont., Canada.

Highlights:

• BMI Group to anchor partnership with $200-million planned investment;
• Up to $30-million in initial non-dilutionary financing to advance the Red Rock converter toward FID (final investment decision);
• Rock Tech retains full operational control and project execution of the Red Rock converter;
• Rock Tech's proven Guben converter design leveraged to accelerate development and reduce risks;
• The investment builds on the recently published partnership with Siemens Canada to integrate digital twin and automation technology;
• The partnership reinforces the strategic critical raw material co-operation between Canada and Europe through BMI Group's European investor relationships.

Strategic partnership structure and $200-million investment

The partnership is expected to be structured as a general partner/limited partner arrangement, with Rock Tech controlling the general partner and the BMI Group acting as the lead limited partner and anchor investor. Under the proposed structure, Rock Tech will retain full control and responsibility for project development, engineering and operations, as well as all key technical, commercial and strategic decision making.

The BMI Group intends to invest $200-million in the project as part of a broader equity structure to be finalized as the project advances. Rock Tech, together with additional partners, is expected to contribute additional equity capital over time. The joint objective is to build processing capacity in Canada -- strengthening value creation, planning certainty and supply security for North American industrial offtakers.

"BMI Group's significant investment is a strong market signal. An experienced Canadian partner committing at this level demonstrates that our project is not only technically and economically compelling -- it also enjoys the confidence of professional investors," said Mirco Wojnarowicz, chief executive officer Rock Tech. "This partnership structure reflects our philosophy: We bring the technology, the operational expertise and the proven converter concept. Our partners invest the capital with expected high returns. Together, we deliver."

Initial financing to advance site development and feasibility study

To support near-term development activities, including a feasibility study, the parties intend to initiate a non-dilutionary financing program of up to $30-million, which is expected to include contributions of both partners and government funding programs, whereby each dollar contributed by Rock Tech shall be matched by the BMI Group and government funding. This financing is targeted to advance engineering, environmental and permitting work and early site development activities in preparation for a final investment decision by end of 2026.

The Red Rock converter is based on Rock Tech's Guben, Germany, project, which is fully engineered, fully permitted and designated as a strategic project under the European Union Critical Raw Materials Act and where Rock Tech has invested over $65-million to date. Leveraging this proven design is expected to reduce development timelines and execution risk and transfer proven technical know-how to Canada.

Strategic location and infrastructure at Red Rock

The Red Rock converter will be developed on the BMI Group's industrial site in Red Rock, Ont., approximately 100 kilometres east of Thunder Bay and 60 kilometres south of Rock Tech's Georgia Lake lithium deposit. The 337-acre site benefits from established infrastructure, including approximately 120 megawatts of power capacity, access to natural gas, road connectivity and direct access to CPKC Rail's transcontinental mainline, supporting efficient movement of materials and equipment.

BMI Group's industrial infrastructure platform is designed to support large-scale project deployment, enabling streamlined site development and reducing timelines from permitting through to construction. By combining Rock Tech's lithium conversion expertise with BMI's industrial infrastructure platform and international investor network, the partnership strengthens the project's positioning within Canada's emerging critical minerals, industrial and defence supply chains.

"As long-horizon developers, BMI Group sees its partnership with Rock Tech as one that will position Northwestern Ontario as a key hub in sovereign defence and battery materials supply chains. Our Red Rock platform provides industrial-ready infrastructure that compresses timelines from site selection to production. This investment reflects our confidence in Rock Tech's technology, market strategy, leadership and long-term vision. Through our Canadian and European investor base, we are aligned on the need for secure, allied critical minerals processing capacity and the multisector co-ordination to get it done," said Paul Veldman, chief executive officer of BMI Group.

Siemens partnership to deliver digital twin and advanced automation

At PDAC 2026, Canada's largest mining expo, Rock Tech signed a partnership agreement with Siemens to provide state-of-the-art industrial automation technology and a full digital twin for the red rock converter. The digital twin -- a real-time virtual replica of the plant -- will enable continuous performance optimization, predictive maintenance and derisked commissioning, consistent with the highest operational standards.

The integration of this technology underlines Rock Tech's commitment to delivering a world-class, future-proof industrial asset for Canada's critical minerals value chain that is fully replicable to scale production with the growing North American lithium demand. These efforts support G7 critical minerals co-operation and position the Red Rock converter as a reference project for sovereign, resilient, sustainable and scalable lithium conversion.

Strategic significance for North America and Europe

Rock Tech is advancing an integrated lithium platform in Canada, linking upstream supply from its Georgia Lake project with downstream production at the Red Rock converter. The project is positioned to establish a domestic, IRA- (Inflation Reduction Act) and CUSMA-aligned (Canada-United States-Mexico Agreement) supply chain from mine to battery-grade lithium salts, strengthening Canada's critical minerals processing capacity and supporting the development of integrated North American and European supply chains.

The BMI Group's participation introduces a transatlantic investor base, including Dutch firm Business EQ Investments, aligned with the development of critical minerals infrastructure across Canada and Europe. Together, the partnership combines Rock Tech's lithium conversion expertise with BMI's industrial infrastructure platform and international investor relationships.

The advancement of the partnership remains subject to the negotiation of definitive agreements and the satisfaction of customary technical, financial, and regulatory conditions.

About Rock Tech Lithium Inc.

Rock Tech is enabling the battery age by making the battery industries in Europe and North America more independent and competitive. The company's goal is to ensure the supply of high-quality, locally produced lithium -- supporting a resilient, sustainable and transparent value chain from mine to battery-grade material.

Rock Tech relies on responsible sourcing, state-of-the-art and proven technologies and a clear focus on circular economy principles. The company's lithium converter projects in Guben, Germany (24,000 tonnes LHM (lithium hydroxide monohydrate) per year), and Ontario, Canada (up to 32,000 tonnes LCE (lithium carbonate equivalent) per year), form the foundation for a stable and regional supply to the battery and automotive industries. The Guben converter has been recognized as a strategic project under the EU Critical Raw Materials Act.

The raw materials for Rock Tech's converter projects are sourced exclusively from verifiably ESG-compliant (environmental, social and governance) suppliers. In Canada, Rock Tech relies, among other sources, on its wholly owned Georgia Lake project, which ensures a stable and sustainable supply for the North American market and is being developed in close partnership with local indigenous communities. By integrating recycled materials, the company aims to close the local battery loop.

With its facilities, Rock Tech makes a central contribution to battery-grade material sovereignty and the achievement of climate targets. The company works in partnership with industry, policymakers and community groups and is committed to open communication and the highest environmental standards.

We seek Safe Harbor.
