Toronto, ON, September 17, 2025 – Rock Tech Lithium Inc. (TSX-V: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the “Company” or “Rock Tech”) is pleased to announce a significant milestone in the development of its Guben Lithium Converter. Following a comprehensive update to its operational expenditure (OpEx) model, the Company anticipates a reduction of approximately 23% in the modeled cost of producing lithium hydroxide – from approximately EUR 5,033 per ton to EUR 3,878 per ton (based on an annual output target of 24,000 tons of lithium hydroxide). This equates to an annual project OpEx reduction of approximately EUR 27.7 million, from EUR 120.8 million to EUR 93.1 million.

The modeled reduction reflects a combination of updated cost inputs across several key areas.

• Transport and Logistics: Transport and logistics expenses are projected to decline by EUR 11.7 million (47%), from EUR 25 million to EUR 13.3 million following the adoption of a revised logistics concept, which accounts for 42.2% of the total projected decrease in OpEx. The most significant component of this decrease stems from an updated spodumene supply contract with more favorable Incoterms, reducing shipping obligations and expected logistics costs by EUR 10.4 million.
•  
• Reagent Procurement: Revised supplier offers reduce reagent procurement costs by EUR 2.8 million, from EUR 25.9 million to EUR 23.1 million, contributing approximately 10.1% of the total projected savings.
•  
• Fixed Costs: Refined estimates of annual fees, office expenses, insurance coverage and IT costs are projected to decrease by EUR 4.2 million, from EUR 10 million to EUR 5.8 million, accounting for approximately 15.2 % of total OpEx savings.

• Leach Residue Reuse: The Company expects a positive cost impact of up to EUR 6.3 million by reusing leach residues instead of disposing of them, under a memorandum of understanding with Schwenk Zement GmbH & Co KG, a well-known German company in the cement industry. This initiative contributes approximately 22.7% of the total OpEx reduction. The companies intend to finalize binding offtake agreements for the leach residues in due course.
•  
• Additional Savings: In addition, the Company expects to further reduce its costs through maintenance savings and refined labor estimates, resulting in an additional EUR 2.7 million in project OpEx reduction.

Increased energy costs are expected to be mitigated by a sustainable long-term energy supply agreement currently under negotiation with Enertrag SE.[1] This cost improvement positions Rock Tech as an internationally competitive player in the lithium-refining market.

“This significant cost reduction is a major step forward,” says Mirco Wojnarowicz, CEO of Rock Tech. “In today’s volatile market, establishing a lean and competitive project is not just beneficial—it’s essential. For our equity and debt financing partners, OpEx is one of the most critical benchmarks for project viability. By reducing our modeled costs by 23%, we are not only improving competitiveness but also significantly strengthening the financing case for Guben.”

The Company is also conducting a parallel review of capital expenditures (CapEx). An updated financial model and full profitability analysis will be published once the review is complete in the coming weeks.

Rock Tech remains committed to building one of Europe’s first lithium hydroxide converters, supporting the transition to sustainable mobility with reliable, local supply of critical battery materials.

Rock Tech Lithium Inc. is pleased to announce the completion of an engineering study that confirms the economic viability and operational feasibility for the construction and operation of a Lithium conversion facility in Ontario, Canada.  

Rock Tech’s CEO Dirk Harbecke comments: “The Scoping Study supports our North American plans with a strong business case. We believe in the tremendous opportunity our projects will bring for the region. Our experience also shows that world-class partners and strong political support are critical for the success of Lithium projects. This is essential in challenging markets.”  

Building on its proven success in Europe, where Rock Tech’s engineering team has advanced a fully permitted Converter in Germany with €100 million in secured government funding and is moving towards a Financial Investment Decision (FID) at the end of this year, the team has now completed a Scoping Study for a second Converter to be built in Ontario, Canada. The study confirms that Rock Tech can transfer a substantial portion of its technical expertise from the German Converter to Canada. It is estimated that up to 80% of basic engineering can be applied, resulting in significant cost saving and an accelerated timeline. Considering Canadian and Ontario jurisdictional, environmental, and operational aspects, the Company has developed a robust CAPEX and OPEX model based on the fully permitted Guben Converter, as well as a strong project execution strategy and time schedule. This approach of replicating Rock Tech’s proven strategy from the Guben Converter not only accelerates project development, but also provides a competitive advantage to constructing the first Converter in Ontario.  

Specifically, the Company proposes to build and operate a Converter with a capacity of up to 32 ktpa LCE in Red Rock, Ontario, located 110 km northeast of Thunder Bay. The lithium raw material (spodumene concentrate) will be locally sourced from the Company’s Georgia Lake Project and other Lithium mining projects in Ontario and Canada. The project benefits from Rock Tech’s advanced merchant refining competencies and is prepared to become a regional Lithium refining hub. The proposed Converter will be designed to produce Lithium Carbonate or Lithium Hydroxide Monohydrate A final decision on output material will be made in the coming months based on market needs.  

Jennifer Main, COO for the Ontario Converter Project adds: “We successfully validated our knowledge transfer capabilities and have laid out a realistic path to bringing Lithium conversion to Ontario. Our proven experience in Guben provides Rock Tech with a strong competitive edge and demonstrates our leadership in advancing lithium processing in Ontario before the end of the decade.”

Rock Tech Lithium Inc. is pleased to announce the findings of a peer-reviewed study published by the German Lithium Institute. The study finds that by-products from Rock Tech’s Lithium conversion process can be used as precursor material in the cement industry.  Specifically, it has been confirmed that leached spodumene concentrate (LSC) generated during the production of lithium from spodumene holds substantial industrial potential. The material, primarily composed of aluminosilicates, can be used in the cement industry as an additive for cement, replacing previously used fly ash, a now slowly depleting by-product of coal-fired power generation. This means that the by-products of Rock Tech’s lithium production can ensure the regional supply security of the German cement industry with LSC and help reduce CO2 emissions. 

Furthermore, it has been shown that the compressive strength of Portland cement, the most used type of cement worldwide, increases by ten percent when 20 percent LSC is added—regardless of the origin of the spodumene used. The process for producing and utilizing the LSC has been submitted for a patent.  

The study was conducted within the Mineralogy and Geochemistry research group at the Martin Luther University Halle-Wittenberg by doctoral candidate and ITEL scholarship holder Julia Woskowski. Dr. Andreas Neumann, a member of the research group, explains: “The phase-out of coal and the transformation of the steel industry will sooner or later lead to changed or disappearing material streams that have been significant for the cement industry in terms of CO2 savings and product portfolio. The LSC from lithium production has the potential to compensate for these depleting material streams in the future.” 

Jannik Schmitz, Supply Chain Manager at ITEL shareholder Rock Tech Lithium, adds: “ITEL’s study takes us a big step further on our path to CO2 neutrality and becoming the first zero-waste lithium company worldwide. It is important to note that the suitability of LSC as a cement additive is independent of the origin of the spodumene used. This confirms our choice of production process and our procurement strategy to source spodumene from several sustainably producing sources.” 

The study was supported by ITEL’s shareholding companies, Rock Tech Lithium Inc., GP Günter Papenburg AG, and SCHWENK Zement GmbH & Co. KG. SCHWENK offers comprehensive supply of cement, concrete, sand & gravel, and pumping services in Germany. Dr. Thomas Neumann, Head of Research and Development at SCHWENK, explains: “The use of industrial residues from lithium production in cements and concretes significantly contributes to the conservation of valuable natural resources. Through innovative material use, we make an important contribution to achieving our sustainability goals. By integrating these residues, we can not only reduce environmental impact but also decrease CO2 emissions.” 

Rock Tech plans to build Europe’s first lithium converter in Guben, Brandenburg. With an annual production capacity of 24,000 tons of lithium hydroxide, the converter can provide material for the construction of 500,000 electric batteries. Thus, the converter forms an important component of the battery value chain. Soon, capacities for material recycling will be developed. Additionally, the company aims to become the first zero-waste lithium company in the world through the complete reuse of byproducts. The company benefits from regional value chains and short distances.
