Toronto, Ontario – July 27, 2026 – Rock Tech Lithium Inc. (“Rock Tech” or the “Company”) (TSX-V: RCK) (OTCQX: RCKTF) is pleased to announce that it has signed a binding long-term offtake agreement dated July 24, 2026, with Transamine SA (“Transamine”), a Geneva-based global commodity trading house, for spodumene concentrate produced at the Company’s wholly owned Georgia Lake project (“Georgia Lake”) in Ontario, Canada. The agreement supports a long-term commercial pathway for Georgia Lake while reflecting growing market confidence in Rock Tech’s integrated Ontario strategy. The agreement currently contemplates deliveries beginning in 2028, subject to the contractual delivery provisions and any adjustments agreed by the parties following completion of the definitive feasibility study.

The agreement marks another important step in advancing Rock Tech’s integrated Ontario lithium supply chain: it secures long-term commercial pathway for full planned production of an estimated minimum of 100,000 dry metric tonnes per year of spodumene concentrate from Georgia Lake’s while maintaining flexibility for the Company to capture additional value through domestic lithium conversion. The agreement also provides a framework for a development prepayment facility of up to US$80 million to support the Georgia Lake Project.

Binding Offtake for Georgia Lake Concentrate

Under the agreement, Transamine will purchase spodumene concentrate from Rock Tech over an initial term of seven years, starting in 2028, which may be renewed annually by mutual agreement for up to five additional years. Contracted volumes ramp from 50,000 dry metric tonnes during the first year of deliveries to 100,000 dry metric tonnes annually thereafter, subject to a ±10% tolerance in favour of Rock Tech and terms and conditions of the agreement. The quantities and timeline will be reviewed and mutually adjusted based on the results of the definitive feasibility study.

Pricing references the Fastmarkets spodumene concentrate benchmark (min. 6% Li₂O, CIF China), adjusted for delivered grade. The agreement incorporates a qualified floor price subject to specified resale-market, inflation-adjustment and project-financing provisions.

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. Together with the prepayment facility, the agreement brings us another step closer to building an integrated mine-to-converter platform and supporting 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.

• Rock Tech Lithium has entered into an option agreement to acquire a 100% interest in the Victory Project, a 9,875-hectare lithium exploration property in Northwestern Ontario from Bounty Gold Corp. and Last Resort Resources Ltd.

• The Victory Project hosts two known spodumene-bearing LCT pegmatite occurrences at surface, with selective grab samples returning up to 5.11% Li₂O at the Last Resort pegmatite and up to 3.48% Li₂O at the Bounty pegmatite.

• The two known spodumene-bearing occurrences are located approximately 6 km apart, defining a broad linear area of exploration interest.

• The Property benefits from proximity to key infrastructure, including the Trans-Canada Highway, rail access, electrical transmission infrastructure and a natural gas pipeline, supporting exploration activities and, if warranted by future exploration results and technical studies, potential future development opportunities.

• The Victory Project represents an early step in Rock Tech’s regional consolidation strategy, aimed at building a broader Ontario lithium supply chain to support future economic prosperity and continued sovereignty, anchored by Georgia Lake and connected to the proposed Red Rock Converter.

Toronto, Ontario – June 22, 2026 – Rock Tech Lithium Inc. (“Rock Tech” or the “Company”) (TSX-V: RCK) (OTCQX: RCKTF) is pleased to announce that it has entered into an option agreement dated June 17, 2026 (the “Option Agreement”) with Bounty Gold Corp. (“Bounty”) and Last Resort Resources Ltd. (“Last Resort”) to acquire a 100% interest in the Victory Project (the “Victory Project”, the “Project” or the “Property”), a 9,875-hectare lithium exploration property located approximately 45 km east of Kenora in Northwestern Ontario. If exploration is successful and subject to further technical evaluation, the Victory Project could represent a potential future source of lithium-bearing minerals for Rock Tech’s planned made-in-Ontario lithium supply chain, supporting the province’s EV and battery ecosystem and its emerging advanced manufacturing and defence sectors.

Victory complements the Company’s Georgia Lake Project and proposed Red Rock Converter by adding an additional exploration-stage lithium property to the Company’s Ontario asset portfolio. The Property hosts two known spodumene-bearing lithium-cesium-tantalum (“LCT”) pegmatite occurrences at surface and is located near the Trans-Canada Highway and nearby CPKC rail access. Rock Tech believes the Property provides prospective exploration opportunities and, if successfully advanced, could represent a potential future source of spodumene feedstock for the Company’s broader Ontario mine-to-converter strategy, subject to successful exploration and further technical evaluation.

Developing domestic sources of lithium feedstock is increasingly important as Ontario, Canada and allied economies seek to build secure, domestic critical minerals supply chains. By combining exploration and development opportunities with downstream conversion capacity, Rock Tech aims to help reduce dependence on overseas processing while supporting the growth of a secure North American lithium supply chain serving the EV and battery ecosystem and helping supply critical materials required by emerging advanced manufacturing and defence sectors.

Exploration Potential in an Infrastructure-Proximal Setting

The Victory Project hosts two known spodumene-bearing pegmatite occurrences: the Last Resort pegmatite and the Bounty pegmatite. These occurrences contain observed spodumene-bearing pegmatite mineralization at surface and provide multiple targets for future exploration.

The Last Resort pegmatite is the Company’s initial priority target. Selective grab sampling from the occurrence has returned values of up to 5.11% Li₂O. The occurrence has been mapped at surface over approximately 200 metres of strike length and up to approximately 30 metres in width. The occurrence has not been drill-tested, and the extent of mineralization beyond the currently mapped exposure, including its depth extent, grade continuity and overall geometry, has not been established. Additional exploration, including drilling, will be required to evaluate the extent, continuity and significance of the observed mineralization.

The Bounty pegmatite, located approximately 6 km from the Last Resort pegmatite, has been mapped at surface over approximately 375 metres of strike length and up to approximately 60 metres in width. Spodumene-bearing samples from the Bounty occurrence have returned values of up to 3.48% Li₂O. The occurrence has not been drill-tested, and its depth extent, grade continuity and overall geometry have not been established.

The approximately 6 km linear area between the two known spodumene-bearing occurrences remains largely unexplored and will be evaluated through future exploration programs. Rock Tech intends to evaluate this corridor through staged fieldwork, including prospecting, geological mapping, sampling and, subject to results, targeted drilling. While mineralized continuity between the Last Resort and Bounty occurrences has not been established, the corridor represents a logical focus for future exploration.

Strategic Fit Within Rock Tech’s Ontario Lithium Platform

Rock Tech’s Ontario strategy is anchored by the Georgia Lake Project and the proposed Red Rock Converter. The addition of the Project provides the Company with additional exposure to lithium exploration opportunities in Northwestern Ontario and complements its existing asset base in the province.

The Georgia Lake Project and the Victory Project are separate mineral properties. Information, mineralization, mineral resources, mineral reserves and exploration results relating to the Georgia Lake Project are not necessarily indicative of mineralization, exploration potential or future results at the Victory Project.

Victory fits within Rock Tech’s broader strategy of building a regional lithium platform around infrastructure-proximal assets that can be integrated into Ontario’s existing transportation network. Similar to Georgia Lake, the Victory Project benefits from proximity to established road and rail infrastructure, including the Trans-Canada Highway and nearby CPKC rail access. These characteristics are important to Rock Tech’s development approach, which is focused on identifying assets that can be evaluated through staged exploration programs and, if warranted by future exploration results and technical studies, considered for further advancement.

The Project is located approximately five hours by road from Rock Tech’s proposed Red Rock Converter, creating a geographic connection within the Company’s Ontario mine-to-converter strategy. If future exploration is successful and subsequent technical studies support further advancement of the Project, Victory may provide Rock Tech with additional optionality around future spodumene feedstock supply. Potential development and processing alternatives, including off-site processing, integration with existing or future regional infrastructure, or other project-specific pathways, would be evaluated only after additional exploration, technical studies and metallurgical testwork.

The acquisition of Victory reflects Rock Tech’s disciplined approach to building a regional lithium platform in Northwestern Ontario. By securing prospective lithium assets located near existing infrastructure and within reach of the proposed Red Rock Converter, the Company continues to strengthen the foundations of a made-in-Ontario critical minerals supply chain capable of supporting future battery and advanced manufacturing industries.

“The Victory Project is a natural fit within our strategy of building a made-in-Ontario lithium supply chain,” said Mirco Wojnarowicz, CEO of Rock Tech. “Ontario has the resources, infrastructure and existing industrial base to become a leader in battery materials, including for the EV, advanced manufacturing and defence sectors. This strategic acquisition gives Rock Tech exposure to a prospective spodumene-bearing property with strong infrastructure attributes, while the option structure allows us to test the project through staged exploration before committing the majority of the acquisition consideration.”

Transaction Terms

Under the Option Agreement, Rock Tech may acquire a 100% interest in the Victory Project by making aggregate payments of CAD $600,000 in cash and issuing CAD $400,000 in Rock Tech common shares over a 24-month period. The payments are staged, with CAD $150,000 in cash and CAD $100,000 in shares payable on signing, and the balance payable in two additional tranches on the 12-month and 24-month anniversaries of the Option Agreement.

The vendors will retain a 2.0% net smelter return royalty on the Victory Project. Rock Tech will have the right to purchase 1.0% of the NSR royalty for CAD $1.0 million at any time prior to a construction decision.

Additional milestone payments will become payable only upon the publication of future NI 43-101 (defined below) compliant mineral resource estimates, if any, on the Victory Project, including CAD $500,000 upon publication of a maiden mineral resource estimate of at least 10 million tonnes grading at least 1.0% Li₂O, CAD $1.0 million upon publication of a measured and indicated mineral resource estimate exceeding 25 million tonnes grading at least 1.0% Li₂O, and CAD $1.5 million upon publication of a measured and indicated mineral resource estimate exceeding 50 million tonnes grading at least 1.0% Li₂O. The foregoing resource thresholds are contractual payment milestones only and do not constitute estimates of mineral resources or mineral reserves on the Victory Project.

The transaction remains subject to customary conditions, including acceptance of the TSX Venture Exchange. Any common shares issued pursuant to the Option Agreement will be subject to applicable securities law resale restrictions and any hold periods required by the TSX Venture Exchange. The transaction is an arm’s-length transaction and no finder’s fees are payable in connection with the transaction.

“We have always believed the Victory Project is prospective for additional exploration, and the surface geology has consistently supported that view,” said Jace Angell, President of Last Resort. “Rock Tech brings an established presence in Ontario and a clear strategy for building an integrated lithium business in the province. We are pleased to see the project move into its next phase.”

“Rock Tech’s Ontario strategy makes it a strong technical and strategic partner for the Victory Project,” said Jason Leblanc, President of Bounty Gold. “The Property is still at an early exploration stage, but the known spodumene-bearing occurrences, infrastructure setting and regional context support a systematic exploration program. We look forward to seeing the results of Rock Tech’s planned work program.”

Supporting Rock Tech’s Ontario Investment Strategy

The Victory Project reflects Rock Tech’s continued commitment to investing in Ontario’s critical minerals sector. Together with the Georgia Lake Project and the proposed Red Rock Converter, the Victory Project strengthens the Company’s Ontario asset base and expands its portfolio of prospective lithium exploration properties.

Rock Tech intends to advance the Victory Project through a staged exploration program focused on validating known spodumene-bearing occurrences, testing extensions along strike and evaluating the underexplored corridor between the Last Resort and Bounty occurrences.

The Victory Project is an early-stage exploration property. While spodumene-bearing pegmatites have been identified at surface, there has been insufficient exploration to define a mineral resource and there can be no assurance that further exploration will result in the delineation of a mineral resource or that the Project will ultimately prove to be economically viable.

Technical Disclosure

Certain technical information contained in this news release is derived from historical exploration work completed by previous property owners and operators. While Rock Tech has reviewed available historical records, the Company has not independently verified all historical exploration information and readers should not place undue reliance on historical exploration results pending completion of additional verification work. The historical exploration information referenced in this news release should not be interpreted as a mineral resource estimate or mineral reserve estimate. Additional exploration activities, including field verification, confirmatory sampling and drilling, will be required to verify historical results and evaluate the extent, continuity and significance of the reported mineralization.

The scientific and technical information in this news release has been reviewed and approved by Cameron Andrews, P.Eng., a “qualified person” as defined in National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).

The sample results disclosed in this news release are from selective grab samples and are not necessarily representative of mineralization across the Victory Project. Grab samples are inherently selective in nature and should not be relied upon as representative of average grade, thickness or continuity of mineralization. Rock Tech has reviewed available historical reports, sampling records and assay information provided by the vendors; however, the Company has not completed independent field verification, confirmatory sampling or twinning of historical results.

Key program highlights include:

• Ontario’s Critical Minerals Processing Fund (“CMIF”) helped demonstrate potential to unlock real value at the Georgia Lake Project.
• Collaboration with Queen’s University and STARK Resources demonstrated the effectiveness of government, industry, and research partnership.
• Ore-sorting test work removed approximately 25 to 45 per cent of waste material before downstream processing. ¹
• The upgraded material stream improved ore quality by approximately 1.4x to 1.8x¹.
• Early engineering work identified a potential pathway to materially reduce future crushing and concentrator capital costs by up to 50 per cent¹.
• The Georgia Lake Project further supports Rock Tech’s broader Ontario mine-to-converter strategy alongside the planned Red Rock Converter.

Toronto, Ontario – May 19, 2026 – Rock Tech Lithium Inc. (TSX-V: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the “Company” or “Rock Tech”) is pleased to announce the successful completion of its Ontario Critical Minerals Innovation Fund supported ore-sorting program for the Georgia Lake Lithium Project (“the Project”) in Northern Ontario. The Project is part of Rock Tech’s broader Ontario mine-to-converter strategy and, alongside the planned Red Rock Converter, supports the development of a domestic, made-in-Canada sovereign defence and battery materials supply chain.

Completed in partnership with Queen’s University and STARK Resources, the ore sorting program evaluated UV Laser-based sorting from Optimum N.V. and X-ray Transmission (“XRT”) sensor-based sorting from allmineral Aufbereitungstechnik GmbH & Co. KG for the pre-concentration of mineralized material from the Project (refer to Press Release – Rock Tech Lithium Receives $388,074 in Funding from Ontario’s Critical Minerals Innovation Fund, dated June 23, 2025).

Test work was conducted on two sample sets: selected drill core used to establish and calibrate sorting algorithms, and a blended surface-derived sample used for small-scale testing. Testing was completed under controlled conditions at both ore sorting test facilities using pilot-scale equipment.

The program indicates a pathway to improve process efficiency and reduce future capital and operating costs, which, if successful, could strengthen the long-term competitiveness of the Project and support a more resilient Ontario critical minerals supply chain.

The results provide a foundation to restart key Georgia Lake development activities, including drilling, additional cost-optimizing engineering, and workstreams that support a future Definitive Feasibility Study.

“These results demonstrate how government, industry and research partnerships produce innovation that can directly strengthen the economics and competitiveness of strategically important critical minerals projects,” said Mirco Wojnarowicz, CEO of Rock Tech. “Backed by the Ontario government’s investment through the CMIF, our work positions Georgia Lake to be more resilient and competitive through lithium price cycles and supports Rock Tech’s broader integrated lithium strategy in Northern Ontario, which can help bolster economic security and long-term defence readiness through the development of a made-in-Canada critical minerals supply chain.”

Government-Industry-Research Partnership Unlocks Ontario Critical Minerals Innovation

With support from the Ontario government, through the Critical Minerals Innovation Fund, Rock Tech worked with Queen’s University and STARK Resources, a Germany-based specialist in sensor-based ore sorting and mineral processing technology, to evaluate practical technologies that improve processing efficiency, reduce waste, strengthen the long-term competitiveness of the Project, and support Ontario’s efforts to build a more resilient domestic critical minerals supply chain.

“The Critical Minerals Processing Lab is proud to have collaborated with Rock Tech Lithium and Stark Resources on this important project, which advanced our understanding of lithium mineral processing characteristics and contributed to the advancement of the Georgia Lake project” said Charlotte Gibson, Assistant Professor & Associate Head for Robert M Buchan Department of Mining. “This innovative process development work was made possible through the support of the CMIF, whose investment is helping drive critical minerals processing innovation and strengthen Ontario’s critical minerals value chain.”

Advancing the Next Phase of Development at the Georgia Lake Lithium Project

The results arrive at an important moment for Ontario’s critical minerals sector. While lithium markets have experienced near-term volatility, governments and industry across North America and Europe continue to move aggressively to secure regional battery and critical minerals supply chains.

The Project was the subject of a 2022 Pre-Feasibility Study, which outlined a conventional mine and concentrator development concept based on a 1.0 million tonne per year concentrator. The 2022 PFS contemplated a 9-year mine life, targeted production of approximately 100,000 tonnes per year of 6% spodumene concentrate, and an Indicated Mineral Resource of approximately 10.6 million tonnes at 0.88 per cent Li₂O and an Inferred Mineral Resource of approximately 4.2 million tonnes at 1.00 per cent  Li₂O.

The PFS estimated a pre-tax NPV of USD$223 million, an after-tax NPV of USD$146 million, a pre-tax IRR of 47.8 per cent, and an after-tax IRR of 35.6%, based on an average life-of-mine SC6 price of USD$1,500 per tonne. The PFS also estimated pre-production capital costs of USD$192 million, life-of-project capital costs of USD$291 million, total life-of-project operating costs of USD$536 million, and AISC of USD$1,082 per tonne of concentrate (see Press Release – Rock Tech Lithium completes Pre-Feasibility Study for its Georgia Lake Project dated November 16, 2022).

Against this PFS baseline, the CMIF-supported ore sorting results indicate a potential pathway to further improve project economics in future technical studies. The observed 1.4x to 1.8x upgrade factor means that sorted material can carry materially higher lithium grade into downstream processing than the original feed stream, improving concentrator efficiency and potentially allowing lower-grade material to be considered in future mine planning scenarios.

Similarly, the potential to reduce crushing and concentrator plant capital costs by up to 50 per cent is expected to be driven by a combination of ore sorting and plant specification optimization, providing an opportunity to optimize overall plant design. If confirmed through further engineering and study work, this could materially improve the capital intensity and investment case for the next phase of Georgia Lake development.

As part of this renewed focus, Rock Tech has begun preparations for a potential future drilling program and the next phase of technical studies, including workstreams that could support a Definitive Feasibility Study. These activities would be designed to support resource growth, improve geological confidence, and provide additional data for future mine planning and project development work.

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

The successful completion of the CMIF-supported ore sorting program strengthens this strategy by indicating a potential pathway to improve the cost structure and development flexibility of the Project. By reducing the amount of waste material processed through the concentrator, ore sorting may support lower operating costs, improve processing efficiency, and provide greater optionality in future mine planning and throughput scenarios.

“Georgia Lake remains foundational to Rock Tech’s Ontario strategy,” said Dirk Harbecke, Chairman of Rock Tech. “These results strengthen the project’s long-term economics and profitability and reinforce the strategic importance of an integrated lithium supply chain in Ontario. As North America and Europe work to secure reliable sources of critical minerals, projects like Georgia Lake and the Red Rock Converter become increasingly important pieces of allied industrial infrastructure.”

Next Steps

Building on the successful outcomes of the program, Rock Tech expects that a future value engineering phase would evaluate the combined impact of ore sorting integration, plant design optimization, and alternative execution strategies across the crushing plant, concentrator plant, and related infrastructure. The results of the CMIF-supported program are conceptual in nature and do not define final economic outcomes, mineral reserve estimates, or plant-scale design changes. Any potential impact on capital costs, operating costs, project economics, mineral reserves, or development plans will require further engineering, feasibility-level studies, and appropriate technical disclosure.

Ontario Innovation Supporting a Stronger Critical Minerals Supply Chain

“Ontario is building a made-in-Canada critical minerals supply chain that creates jobs, strengthens our economic security, and reduces our reliance on foreign adversaries,” said Stephen Lecce, Minister of Energy and Mines. “Through the Critical Minerals Innovation Fund, our government is backing Ontario innovation that lowers costs, unlocks investment, and accelerates responsible mining development in the North. The success of this project shows how Ontario can lead the world in critical minerals, battery materials, and the technologies that will power the future.”

• Company Files Preliminary Short Form Base Shelf Prospectus and AIF and continues to advance NASDAQ Dual Listing via MJDS Process
• Final Base Shelf Prospectus, if receipted, will be valid for 25 months and is intended to provide the Company with capital markets flexibility

Toronto, ON, April 24, 2026 — Rock Tech Lithium Inc. (TSX-V: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the “Company” or “Rock Tech”) is pleased to announce that it has  filed a preliminary short form base shelf prospectus (“Base Shelf Prospectus”) and Annual Information Form (“AIF”)  with the securities regulators in each of the provinces and territories of Canada. These filings represent a significant and deliberate step in the Company’s strategic roadmap — which the Company expects may be used, subject to receipt and regulatory approvals, in connection with a potential NASDAQ dual‑listing through the Multi-Jurisdictional Disclosure System (“MJDS”), the established bilateral framework between Canadian and U.S. capital markets regulators.

NASDAQ Dual-Listing Readiness via MJDS

Under the MJDS framework, eligible Canadian issuers may file a U.S. registration statement with the U.S. Securities and Exchange Commission (“SEC”) on Form F‑10, which is primarily based on Canadian disclosure documents, including the Company’s base shelf prospectus. This bilateral system substantially reduces regulatory duplication, cost, and processing time, which may streamline the disclosure process for a NASDAQ cross‑listing, subject to SEC effectiveness and NASDAQ approval. Rock Tech’s existing TSX Venture Exchange (the “TSXV”) listing, combined with its 12-month-plus Canadian reporting history and qualifying public float, positions the Company as MJDS-eligible. The NASDAQ filing remains subject to NASDAQ approval.

25-Month Capital Flexibility Window

The final Base Shelf Prospectus, if receipted, will be valid for a period of 25 months from the date of receipt. During this window, Rock Tech retains the option to access capital markets from time to time and in tranches aligned with project milestones — without requiring a full regulatory review for each potential future offering. This significantly reduces execution risk and cost in time-sensitive financing situations.

Institutional Credibility and Market Profile

A filed Base Shelf Prospectus is commonly used by more established TSXV‑listed issuers and is intended to support corporate governance practices, capital markets readiness, and financing flexibility. It is standard practice among established TSXV-listed resource and technology companies operating at Rock Tech’s scale. The filing reinforces Rock Tech’s positioning as a strategic, investment-ready critical minerals platform.

“This filing is about building institutional-grade capital markets infrastructure for tomorrow. Filing our Shelf Prospectus is an important step in preparing for a potential NASDAQ dual‑listing via the MJDS process. A NASDAQ listing, if achieved, is a transformative re-rating event for Rock Tech. It opens our story to the full depth of the North American institutional investor base at exactly the moment our project pipeline — Guben, Red Rock, Georgia Lake — is entering its most consequential phase,” says Rock Tech’s CEO, Mirco Wojnarowicz.

Rock Tech is advancing toward a NASDAQ dual-listing as a cornerstone of its institutional investor strategy. With the Guben Converter holding EU CRMA Strategic Project status and a full permit and engineering package, the Red Rock Converter project in Ontario, Canada carrying a CAD $2.3 billion NPV and a committed capital structure under the GP/LP framework, and the Georgia Lake Mine in Ontario positioned to create North America’s first fully integrated mine-to-battery-grade lithium supply chain, Rock Tech believes the NASDAQ listing, if completed, could serve as a significant re-rating catalyst — expanding visibility, research coverage, and shareholder liquidity across the world’s deepest capital market.

• Multi-phase strategic partnership: The cooperation includes the integration of Siemens Digital Twin technology, as well as evaluation of additional Siemens solutions, services and engineering support, with the goal of positioning Red Rock as a blueprint for future converters in Canada and allied markets.
• Red Rock as a Strategic Contributor to G7 Critical Minerals Supply Chain Cooperation: The partnership strengthens German-Canadian cooperation within the G7 Critical Minerals Production Alliance and positions Red Rock as a reference project for resilient, sustainable, and scalable lithium conversion.

Toronto, ON, March 2, 2026 – Rock Tech Lithium Inc. (TSX-V: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the “Company” or “Rock Tech”) and Siemens Canada Ltd. (Siemens) are pleased to announce that they have signed a non-binding Memorandum of Understanding (MoU) laying the foundation for a long-term, multi-phase strategic partnership to develop state-of-the-art lithium conversion capacity. The signing took place at the Canadian Critical Minerals Forum hosted by Natural Resources Canada (NRCan) during Prospectors and Developers Association of Canada Trade Show and Convention (PDAC) – the world’s leading conference for the mining and minerals industry. At the core of the partnership is the application of Siemens’ cutting-edge digitalization technology – in particular Digital Twin solutions – for the development, construction, and operation of Rock Tech’s planned lithium converter in Red Rock, Ontario.

The partnership translates the strategic critical raw material cooperation between Canada and Germany into concrete, on-the-ground collaboration. Siemens brings German industrial and digitalization expertise to a Canadian flagship project built on the blueprint of the fully permitted, shovel-ready Guben converter in Germany. The public signing underscores the strategic importance of Red Rock for Canada’s efforts to build resilient and sovereign midstream capacity for critical minerals – and reinforces broader Canada-Germany cooperation aligned within the G7 critical minerals supply chain priorities. The parties intend to explore available funding opportunities to support deployment of Digital-Twin technology.

Proven Blueprint Enables Accelerated Execution

The Red Rock converter will be developed based on the fully permitted and engineered facility in Guben, Germany. By transferring this blueprint to Canada, development timelines can be shortened, technical risks minimized, and capital efficiency increased. Leveraging the engineering and permitting work completed in Guben materially reduces execution risk and supports a more efficient path toward final investment decision in Canada. The planned production capacity of up to 32,000 tonnes of LCE per year would be sufficient to supply up to 900,000 electric vehicles annually.

“Red Rock will be Ontario’s first lithium conversion facility and is a key project in Canada’s efforts to rapidly establish domestic critical minerals processing capacity,” says Mirco Wojnarowicz, CEO of Rock Tech Lithium. “Together with our Georgia Lake mining project, we are creating a fully vertically integrated supply chain from rock to battery-grade lithium. A critical minerals corridor, entirely in Ontario.”

Parliamentary State Secretary Stefan Rouenhoff emphasizes: „The Federal Ministry for Economic Affairs and Energy strongly welcomes the deepening of business relations between Rock Tech Lithium and Siemens Canada. At a time when secure and sustainable supply chains for critical raw materials are of strategic importance, this partnership sends a powerful signal for the continued expansion of German-Canadian cooperation.”

Digital Twin Optimizes Efficiency and Sustainability

The collaboration with Siemens provides for the deployment of Digital Twin technology across the entire project lifecycle: from the feasibility study through engineering and construction to operation. Through the virtual, data-driven modeling of processes, energy flows, and material streams, Rock Tech can optimize and validate design, efficiency, emissions, and operational reliability before committing capital. “Our partnership with Rock Tech is built on a shared commitment to developing stronger and more resilient domestic critical minerals processing capacity,” says Faisal Kazi, CEO of Siemens Canada. “By leveraging our digital twin and industrial digitalization technologies, we are supporting the development of lithium conversion in Ontario that could ultimately help support stronger battery supply chains within the G7. This collaboration between our two organizations – both at home in Canada and in Germany – underscores our shared vision for energy security, industrial competitiveness, clean growth, and creating a blueprint for next-generation facilities worldwide.”

Strategic Relevance for Canada and the G7

With midstream lithium processing, the project closes a critical gap in the North American battery value chain. Rock Tech and Siemens share the goal of establishing Red Rock as a strategic project within the G7 Critical Minerals Production Alliance. The partnership is intended to serve as a reference model for further industrial ventures in the critical minerals space, thereby helping to strengthen supply security across the G7 nations.

“This second round of partnerships and strategic investments under the Critical Minerals Production Alliance illustrates how Canada and our G7 allies are moving from ambition to action. Canada, our industry, and our partners are putting real capital behind the secure and sustainable critical mineral supply chains that our economies and defence industries rely on,” said the Honourable Tim Hodgson, Minister of Energy and Natural Resources. “By working with companies like Rock Tech Lithium and Siemens, we are helping deliver the minerals the world needs and the prosperity and security Canadians deserve.”

Long-Term Partnership with Growth Potential

The cooperation is structured in multiple phases, initially focusing on the deployment of Digital Twin technology during engineering and in the feasibility study. In the medium term, the parties are evaluating additional Siemens solutions, services and engineering support for the Red Rock converter, as well as the potential expansion of the cooperation to further projects in G7 member countries. Joint applications for public funding will be pursued with NRCan, the Government of Ontario, and through Canadian-German cooperation programs.

Rock Tech Lithium Inc. (“Rock Tech” or the “Company”) welcomes the Province of Ontario’s approval and launch of the CAD $500 million Critical Minerals Processing Fund (“CMPF”), a milestone initiative designed to accelerate the province’s critical minerals processing capacity and strengthen Ontario’s position in the global battery materials supply chain.

Rock Tech’s proposed Lithium Conversion Facility (the “Converter”) in Red Rock, Ontario directly aligns with the CMPF’s mandate to support midstream critical minerals processing projects in the province. The Converter is designed to deliver domestic lithium conversion capacity for battery-grade products, reduce reliance on offshore processing, and anchor downstream investment in Ontario’s electric vehicle and energy storage supply chain.

The CMPF represents a clear signal to global markets that Ontario is committed to scaling up processing capacity needed to support the energy transition. By enabling new critical mineral projects and midstream processing facilities, the fund will help catalyze investment, create jobs, and anchor long-term economic benefits across the province.

As a technology company advancing its Georgia Lake lithium mining project and a lithium conversion facility in Ontario, located only about 60 kilometers apart, Rock Tech sees the CMPF as an important building block in establishing a regional and integrated lithium battery supply chain. The planned design of the Converter in Red Rock is directly based on Rock Tech’s fully permitted, shovel-ready converter in Guben, Germany, which was recently designated an EU Strategic Project under the European Critical Raw Materials Act (CRMA). This foundation gives the Converter a uniquely advanced and de-risked design — positioning it as one of the most technically mature lithium conversion projects in North America.

“We applaud the Government of Ontario for taking bold action to support critical minerals development,” said Mirco Wojnarowicz, CEO of Rock Tech Lithium. “With the CMPF now approved, Ontario is sending a clear signal that it intends to lead in battery materials. Our Converter in Red Rock, built on the engineering and experience behind our EU CRMA Strategic Project in Germany, is exceptionally well-positioned to help deliver the processing capacity the province needs to compete globally.”

Rock Tech has invested more than 350,000 engineering hours and CAD 65 million into the design of its lithium conversion facilities. The Company will continue to work closely with provincial partners, Indigenous communities, and industry stakeholders to support the development of an integrated, competitive, and resilient lithium supply chain in Ontario.
