TORONTO, September, 22, 2026 /CNW/ – Rock Tech Lithium Inc. (TSXV: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the “Company” or “Rock Tech”) is pleased to announce that it has signed agreements with Siemens Canada to advance the development of a Digital Twin and for Siemens to support Rock Tech’s project team with the ongoing Definitive Feasibility Study (“DFS”)  for the planned Red Rock Lithium Converter in Ontario.

The agreements represent the first implementation phase under the strategic Memorandum of Understanding (“MOU”) signed by the parties in March 2026. The MOU established a roadmap to bring advanced German lithium conversion expertise and industrial digitalization technology to Rock Tech’s planned Red Rock Converter in Ontario.

The MoU includes the development and integration of Siemens Digital Twin technology, as well as the evaluation of additional Siemens solutions, services, and engineering support, with the goal of positioning the Red Rock Converter as a blueprint for future converters in Canada and allied markets.   Siemens’ Digital Twin technology creates a virtual, physics-based model of the plant’s processes, energy flows, and material streams, enabling Rock Tech to test, optimize, and validate design choices, efficiency, emissions, and operational reliability before major capital is committed.  While the first step is to implement a digital process twin, the Digital Twin technology will cover the entire project lifecycle: from the feasibility study through engineering and construction to operations. The parties will also evaluate the potential application of the cooperation to future projects in other G7 countries.

Siemens Canada will also support Rock Tech’s project team by providing specialized support in Process Control, Instrumentation and Automation Architecture as part of the ongoing DFS for the Red Rock Converter. The DFS was launched at the end of June 2026 and is expected to be finalized by mid-December 2026.

The partnership with Siemens strengthens German-Canadian cooperation and supports Rock Tech’s objective of establishing the Red Rock Converter as a strategic contributor to resilient G7 critical minerals supply chains. The Rock Tech–Siemens collaboration provides a concrete industrial example of how German engineering expertise and Canadian resources can jointly build resilient lithium supply chains for the G7.

The post Rock Tech Lithium Closes First Tranche of a CAD$5.2 Million Private Placement with the Majority having been Subscribed by New Strategic Investor in the Guben Converter appeared first on Rock Tech Lithium.

Four weeks ago, I wrote to you that Canada changes everything. This letter is going to be shorter, because the update is simple: we are executing on what we promised, and the environment around us is moving in the same direction as our strategy. Allied governments, including Canada and Germany, and industrial partners are increasingly recognizing the importance of exactly the kind of projects we are building.

1. Red Rock: The DFS Has Started

We have commenced the Definitive Feasibility Study (“DFS”) for the Red Rock Converter, the most important technical milestone on the path to a final investment decision. The DFS is designed to support bankability — engineering depth comparable to FEL3, with a capital cost accuracy of +/-10%.  Early engineering and value-engineering work indicate a credible pathway to materially lower capital costs than assumed in the 2024 Scoping Study. The completed DFS will validate those improvements.

2. Georgia Lake & Victory: Building the Ontario Resource Base

Georgia Lake is the upstream foundation of our made-in-Ontario mine-to-converter strategy. It is an increasingly important strategic asset as Ontario builds domestic critical minerals processing capacity. Georgia Lake combines what few spodumene projects in Ontario can offer at the same time: advanced permitting, a completed PFS, and outstanding infrastructure, grid power and direct access to the Trans-Canada Highway. This combination positions Georgia Lake to be first to market among Ontario’s spodumene projects. And we are working on the first offtake agreement. The second half of 2026 is about growing it on both axes — resource size and project economics:

• Drilling. A drill program is planned for the second half of 2026. The program is designed to materially expand the current ~15 million-tonne resource and test the potential for new discoveries across the roughly 90% of the property that remains unexplored. “Based on historical drill results and geological continuity, we expect the resource to grow toward 30 million tonnes” says our General Manager Canada, Cameron Andrews.   
• DFS. The Georgia Lake DFS contract award is targeted for late August. A key workstream is validating the ore-sorting results we published in May — waste rejection of 25–45% before processing, a pathway to reduce crushing and concentrator capital by up to 50%, and operating cost reductions of approximately 20%. If the DFS confirms these results, Georgia Lake becomes one of the lowest-capital-intensity spodumene projects in North America.

In June, we acquired an option to earn a 100% interest in the Victory Project, a 9,875-hectare lithium exploration property near Kenora from Bounty Gold Corp. and Last Resort Resources Ltd. Victory hosts two known spodumene-bearing pegmatite systems with high-grade surface sampling of up to 5.11% Li₂O and neither has ever been drill tested. Initial exploration later this year will focus on mapping, sampling and targeted drilling to evaluate what we believe could become another meaningful source of feedstock for our Ontario platform.

“Our pre-acquisition technical review indicates that an exploration target in excess of 50 million tons could be possible, if drilling is successful”, adds Cameron Andrews.

The logic is straightforward. A converter without captive feedstock is permanently exposed to spot markets. We are building an Ontario resource base — mine, exploration and land consolidation pipeline, and converter within one province, one jurisdiction, one supply chain. Every metric tonne of resource we add strengthens the long-term competitiveness and economics of the entire platform.

3. Canada Is Moving — Fast

Since my last letter, the policy environment has accelerated. Federal and provincial governments are increasingly recognizing that securing critical minerals and shoring up allied supply chains requires domestic processing capacity.

• The federal government launched the Canada Critical Minerals Accelerator, a CAD 2 billion fund making equity investments, loan guarantees, and offtake agreements to bring projects to FID faster and signed its first agreement within days of launch. These instruments map directly onto our GP/LP structure.
• The First and Last Mile Fund provides CAD 1.5 billion for mining and enabling infrastructure through 2030.
• Canada’s new Defence Industrial Strategy enables the stockpiling of critical minerals under the Defence Production Act. Lithium is now formally a security asset.
• In Ontario, our application under the province’s CAD 500 million Critical Minerals Processing Fund continues to advance through the review process, with the assessment now moving toward its later stages. The province has additionally committed nearly CAD 3.1 billion to support Indigenous participation and ownership in the critical minerals supply chain. This is directly relevant to the partnerships we are building with First Nation communities connected to our projects.
• A small but telling proof point: Ontario’s Critical Minerals Innovation Fund awarded Rock Tech another funding; this time CAD 262,500 to validate crude tall oil, a forestry byproduct, as a low-emission flotation reagent — connecting lithium processing to Ontario’s forestry sector. We shared this announcement with Ontario’s Associate Minister of Forestry and Forest Products, Kevin Holland, last week.

Canada has a bold vision, backed by government policies and action, to become the preferred supplier of responsibly sourced critical minerals and set the foundation for its mine-to-converter strategy. The entire North American supply chain is now being assembled in real time.

4. Guben

Guben remains fully permitted, shovel-ready, and strategically valuable. Strategic investor discussions are advancing on the disciplined terms I described in my letter from June. We are also advancing our internal work on establishing a R&D hub as the anchor of our lithium conversion IP — the knowledge base every future converter is built on.

The next months are about delivery: DFS milestones, drill results, and financing steps. I look forward to reporting on each.

Best regards,

Mirco Wojnarowicz

Option to Convert into Battery-Grade Lithium Chemicals

The agreement is structured to support Rock Tech’s integrated Ontario mine-to-conversion strategy. Should Rock Tech determine that the concentrate is required for its Red Rock Converter, the parties will convert the arrangement into an offtake for battery-grade lithium hydroxide monohydrate and/or battery-grade lithium carbonate, subject to a mutually agreed amendment establishing the applicable specifications, conversion mechanism, pricing, delivery schedule and other terms. Transamine’s take-or-pay commitment continues through and after any such conversion, adjusted for the applicable product, price and delivery terms.

This flexibility allows Rock Tech to sell spodumene concentrate while preserving the option to supply converted lithium chemicals to battery and cathode customers when the planned Red Rock Lithium Converter is developed and commissioned.

“This agreement demonstrates how Rock Tech is turning critical minerals ambition into execution,” said Mirco Wojnarowicz, Chief Executive Officer of Rock Tech. “It provides a long-term, commercial foundation for the Georgia Lake mine’s future production, strengthens our financing pathway, and – together with the prepayment facility – brings us another step closer to building the integrated mine-to-converter platform, with the flexibility to convert raw material into battery-grade lithium chemicals through our Red Rock Lithium Converter and to support a stable, secure supply of battery-grade lithium for Canada and its allies.”

Up to US$80 Million Development Prepayment Facility

To support Georgia Lake project, the agreement provides for a framework for a development prepayment facility of up to US$80 million. The prepayment carries interest at three-month CME Term SOFR plus 2.95% per annum, accruing quarterly, and would be repaid by set-off against concentrate deliveries over a 24-month period beginning with first delivery. Any amount outstanding after that period would become due and payable in cash.

The exact amount and terms of the prepayment will be documented separately and agreed once the definitive feasibility study is complete. Availability of the facility is subject to the satisfaction (or waiver by the buyer) the following conditions precedent:

• full project equity financing committed
• all material permits, licences, land access rights and environmental approvals in place
• no material adverse change
• legal, financial and technical due diligence satisfactory to the buyer
• no unresolved title, land, litigation, environmental or community matter that could delay production
• final assays, impurity profile, metallurgical test work and product specifications available and satisfactory to the buyer.

Dear Friends and Shareholders,

Four weeks ago, I wrote to you that Canada changes everything. This letter is going to be shorter, because the update is simple: we are executing on what we promised, and the environment around us is moving in the same direction as our strategy. Allied governments, including Canada and Germany, and industrial partners are increasingly recognizing the importance of exactly the kind of projects we are building.

1. Red Rock: The DFS Has Started

We have commenced the Definitive Feasibility Study (“DFS”) for the Red Rock Converter, the most important technical milestone on the path to a final investment decision. The DFS is designed to support bankability — engineering depth comparable to FEL3, with a capital cost accuracy of +/-10%.  Early engineering and value-engineering work indicate a credible pathway to materially lower capital costs than assumed in the 2024 Scoping Study. The completed DFS will validate those improvements.

2. Georgia Lake & Victory: Building the Ontario Resource Base

Georgia Lake is the upstream foundation of our made-in-Ontario mine-to-converter strategy. It is an increasingly important strategic asset as Ontario builds domestic critical minerals processing capacity. Georgia Lake combines what few spodumene projects in Ontario can offer at the same time: advanced permitting, a completed PFS, and outstanding infrastructure, grid power and direct access to the Trans-Canada Highway. This combination positions Georgia Lake to be first to market among Ontario’s spodumene projects. And we are working on the first offtake agreement. The second half of 2026 is about growing it on both axes — resource size and project economics:

• Drilling. A drill program is planned for the second half of 2026. The program is designed to materially expand the current ~15 million-tonne resource and test the potential for new discoveries across the roughly 90% of the property that remains unexplored. “Based on historical drill results and geological continuity, we expect the resource to grow toward 30 million tonnes” says our General Manager Canada, Cameron Andrews.   
• DFS. The Georgia Lake DFS contract award is targeted for late August. A key workstream is validating the ore-sorting results we published in May — waste rejection of 25–45% before processing, a pathway to reduce crushing and concentrator capital by up to 50%, and operating cost reductions of approximately 20%. If the DFS confirms these results, Georgia Lake becomes one of the lowest-capital-intensity spodumene projects in North America.

In June, we acquired an option to earn a 100% interest in the Victory Project, a 9,875-hectare lithium exploration property near Kenora from Bounty Gold Corp. and Last Resort Resources Ltd. Victory hosts two known spodumene-bearing pegmatite systems with high-grade surface sampling of up to 5.11% Li₂O and neither has ever been drill tested. Initial exploration later this year will focus on mapping, sampling and targeted drilling to evaluate what we believe could become another meaningful source of feedstock for our Ontario platform.

“Our pre-acquisition technical review indicates that an exploration target in excess of 50 million tons could be possible, if drilling is successful”, adds Cameron Andrews.

The logic is straightforward. A converter without captive feedstock is permanently exposed to spot markets. We are building an Ontario resource base — mine, exploration and land consolidation pipeline, and converter within one province, one jurisdiction, one supply chain. Every metric tonne of resource we add strengthens the long-term competitiveness and economics of the entire platform.

3. Canada Is Moving — Fast

Since my last letter, the policy environment has accelerated. Federal and provincial governments are increasingly recognizing that securing critical minerals and shoring up allied supply chains requires domestic processing capacity.

• The federal government launched the Canada Critical Minerals Accelerator, a CAD 2 billion fund making equity investments, loan guarantees, and offtake agreements to bring projects to FID faster and signed its first agreement within days of launch. These instruments map directly onto our GP/LP structure.
• The First and Last Mile Fund provides CAD 1.5 billion for mining and enabling infrastructure through 2030.
• Canada’s new Defence Industrial Strategy enables the stockpiling of critical minerals under the Defence Production Act. Lithium is now formally a security asset.
• In Ontario, our application under the province’s CAD 500 million Critical Minerals Processing Fund continues to advance through the review process, with the assessment now moving toward its later stages. The province has additionally committed nearly CAD 3.1 billion to support Indigenous participation and ownership in the critical minerals supply chain. This is directly relevant to the partnerships we are building with First Nation communities connected to our projects.
• A small but telling proof point: Ontario’s Critical Minerals Innovation Fund awarded Rock Tech another funding; this time CAD 262,500 to validate crude tall oil, a forestry byproduct, as a low-emission flotation reagent — connecting lithium processing to Ontario’s forestry sector. We shared this announcement with Ontario’s Associate Minister of Forestry and Forest Products, Kevin Holland, last week.

Canada has a bold vision, backed by government policies and action, to become the preferred supplier of responsibly sourced critical minerals and set the foundation for its mine-to-converter strategy. The entire North American supply chain is now being assembled in real time.

4. Guben

Guben remains fully permitted, shovel-ready, and strategically valuable. Strategic investor discussions are advancing on the disciplined terms I described in my letter from June. We are also advancing our internal work on establishing a R&D hub as the anchor of our lithium conversion IP — the knowledge base every future converter is built on.

The next months are about delivery: DFS milestones, drill results, and financing steps. I look forward to reporting on each.

Best regards,

Mirco Wojnarowicz

Toronto, Ontario – July 13, 2026 – Rock Tech Lithium Inc. (“Rock Tech” or the “Company”) (TSX-V: RCK) (OTCQX: RCKTF) is pleased to announce that it has been awarded $262,500 through Ontario’s Critical Minerals Innovation Fund (“CMIF”) to evaluate the use of crude tall oil, a by-product of Ontario’s pulp and paper industry, as potentially locally sourced  flotation reagent for lithium processing.

Crude tall oil may have potential application in mineral flotation processes used during processing to separate lithium-bearing minerals from waste rock, with the objective of improving processing efficiency while supporting a more localized supply chain by leveraging a pulp and paper by-product. This by-product produced by Ontario’s pulp and paper sector and could serve as a new way for Ontario’s pulp and paper industry to monetize this output while enhancing the sustainability and affordability of lithium processing in Ontario, if successfully validated and incorporated into future project design.

Similar to Rock Tech’s recently announced completion of its CMIF-supported ore sorting program (refer to Press Release – Rock Tech Advances Georgia Lake Lithium Project, Identifies Potential Pathway to Reduce Processing CAPEX by Up to 50 per cent, dated May 19, 2026), this project is designed to evaluate whether locally sourced crude tall oil could support future processing efficiency, reduce reliance on imported or conventional reagents and inform future cost-optimization work for the Georgia Lake Project.

Strengthening Ontario’s Critical Minerals Supply Chain Through Innovation

The project arrives at an important moment for Ontario’s critical minerals sector, as the Province of Ontario has identified the development of domestic critical minerals supply chains as a strategic priority, including supply chains supporting advanced manufacturing and energy storage.[1]

The use of crude tall oil as a flotation reagent represents an opportunity to connect two strategically important Ontario industries. By evaluating whether a by-product from the province’s forestry sector can be utilized in lithium processing, the project seeks to improve the sustainability and competitiveness of domestic critical minerals production while creating additional value from existing industrial supply chains.

“We’re proud to have the continued support of the Government of Ontario through this latest intake of the Critical Minerals Innovation Fund,” said Mirco Wojnarowicz, CEO of Rock Tech. “The future of critical minerals competitiveness will be driven not only by what we mine, but by how we process and innovate. This project brings together Ontario’s strengths in critical minerals, forestry, and research to evaluate a practical solution that could reduce emissions, strengthen project economics and create new opportunities for domestic industry. It demonstrates how innovation can help build a more resilient critical minerals supply chain – here in Canada and among allied countries.”

Government, Industry, and Research Working Together

With support from the Province of Ontario through the CMIF, Rock Tech and its project partners will evaluate a practical innovation with direct commercial application. The initiative brings together public investment, industrial expertise, and research capacity to explore technologies that may improve competitiveness while supporting the development of cleaner and more efficient processing methods.

“Northwestern Ontario has the people, resources, and expertise needed to lead the next generation of critical mineral development. This investment will help strengthen connections between our mining and forestry sectors while supporting innovation right here in our region,” said Kevin Holland, MPP for Thunder Bay–Atikokan. “I’m pleased to see Rock Tech, Thunder Bay Pulp and Paper, and Queen’s University working together on a project that has the potential to create new opportunities for local industry and strengthen Ontario’s critical mineral supply chain. Investments through the Critical Minerals Innovation Fund are helping ensure that the economic benefits of resource development stay in Northern Ontario, creating jobs and supporting long-term growth for our communities.”

“This CMIF investment supports an ongoing collaboration between the Critical Minerals Processing Lab at Queen’s University and Rock Tech, advancing lithium process development in Ontario.” said Charlotte Gibson, Assistant Professor and Associate Head at Queen’s University’s Robert M. Buchan Department of Mining. “We are excited to continue working with Rock Tech on this important initiative, which has the potential to establish local reagent supply chains, improving the sustainability and resilience of lithium production in the province.”

The project also highlights the growing opportunity to strengthen ties between Ontario’s natural resource sectors. By creating potential new demand for forestry-derived products within critical minerals processing, the initiative will support the province’s industrial diversification, domestic supply chains, and economic prosperity.

Supporting Rock Tech’s Ontario Mine-to-Converter Strategy

The project forms part of Rock Tech’s broader Ontario strategy, which includes the Georgia Lake Project and the proposed Red Rock Converter in Northwestern Ontario.

Together, these projects are intended to support a vertically integrated, made-in-Ontario lithium supply chain linking domestic resource development with downstream processing capacity. As demand for battery materials continues to grow across North America and Europe, including supporting an expanding range of capabilities in the defence sector, innovative initiatives like this may help strengthen the competitiveness, sustainability and long-term resilience of Ontario’s critical minerals sector and broader economy.
