ROCK TECH LAUNCHES ITS FIRST FIELD PROGRAM AT VICTORY LITHIUM PROJECT IN NORTHWEST ONTARIO

Rock Tech Lithium Inc. has started its first exploration program at the Victory project, a 9,875-hectare lithium property in Northwestern Ontario.

• Rock Tech's first exploration field program at the Victory project, about 45 kilometres east of Kenora, Ont.;
• Crews are advancing exploration at the two known lithium occurrences and exploring a six-kilometre corridor of potential strike extensions that may be part of a much more extensive lithium-bearing system;
• The project lies along the Trans-Canada Highway, with rail, electrical transmission and a natural gas pipeline nearby;
• First results from the program are expected in early 2027, ahead of a planned first drill program later that year.

The first exploration field program marks a pivotal step in unlocking the potentially significant scale of the project. With two large, highly prospective pegmatites situated approximately six kilometres apart, the program is designed to evaluate potential strike extensions and investigate the intervening corridor for further lithium mineralization. This work will help determine whether the two occurrences form part of a more extensive lithium-bearing system, with the potential for a substantially larger mineralized footprint and a significant lithium resource.

Throughout October, a team of geologists and field technicians will advance exploration at the project's two known lithium occurrences, search for new occurrences and identify priority targets for drilling in 2027. The findings will also help assess the project's potential to become an additional source of Ontario lithium for Rock Tech's proposed lithium conversion plant in Red Rock, Ont.

Rock Tech secured an option to acquire 100 per cent of the project in June, 2026. The project lies along the Trans-Canada Highway, with rail, electrical transmission and a natural gas pipeline nearby -- providing access to key infrastructure that many early stage lithium properties in Canada lack.

"Four months after signing the option, our geologists and prospectors are on the ground at Victory," said Mirco Wojnarowicz, chief executive officer of Rock Tech. "What we see is encouraging: high grades at surface, plenty of unexplored ground, and the Trans-Canada-Highway and rail line right next door. This program will provide Rock Tech with independently verified data and drill-ready targets for 2027, while minimizing upfront acquisition costs through an option structure that ties most of the consideration to project results."

"Victory's geological characteristics and proximity to infrastructure make it a compelling fit for Rock Tech's integrated lithium supply chain model," adds Cameron Andrews, general manager Canada of Rock Tech. "The two known lithium occurrences and kilometres of largely untested ground between them indicate potential for significant scale that we are now beginning to assess. This program is a first step toward developing Victory as an additional source of Ontario lithium for our proposed Red Rock converter and an important part of strengthening the province's growing lithium supply chain."

Two surface pegmatites, neither ever drilled

The Victory project currently hosts two lithium-cesium-tantalum (LCT) pegmatites, Last Resort pegmatite and Bounty pegmatite. Pegmatites are coarse-grained rocks that can contain lithium-bearing minerals such as spodumene. Both pegmatites are exposed at surface, with historical samples returning up to 5.11 per cent lithium oxide (Li2O). Neither pegmatite has ever been drilled. The six-kilometre corridor between them has seen little systematic exploration and is a priority area for new discoveries. Alongside sampling and geological mapping, crews are conducting a high-resolution survey of the property to map outcrops, geological structures and pegmatite trends.

Victory project's role in an integrated lithium supply chain

The Victory project represents another important building block in Rock Tech's strategy to establish an integrated lithium supply chain in Ontario, from mine to battery-grade material.

With the proposed Red Rock converter located near the Georgia Lake project, the Victory project -- approximately five hours by road from Rock Tech's planned converter -- offers the potential to contribute additional lithium feedstock to this emerging regional ecosystem.

This is just the beginning. The Red Rock converter is intended to support the development of third party spodumene projects in Ontario and across Canada, providing a local processing solution for their material and helping unlock the potential of a broader domestic lithium supply chain. The Victory project is therefore part of Rock Tech's wider strategy to consolidate its position in Ontario, while building a platform for further growth across Canada and beyond.

Qualified person and technical disclosure

The scientific and technical information in this news release has been reviewed and approved by Cameron Andrews, PEng, a qualified person as defined in National Instrument 43-101 -- Standards of Disclosure for Mineral Projects. The historical results referenced (up to 5.11 per cent Li2O at the Last Resort pegmatite and up to 3.48 per cent Li2O at the Bounty pegmatite) are from selective grab samples, are not necessarily representative of mineralization on the project and have not been fully verified by the company.

The Victory project is an early-stage exploration property with no mineral resource or mineral reserve estimate, and there is no assurance that further exploration will define one. Information on the Georgia Lake project is not necessarily indicative of mineralization at the Victory project. The Red Rock feed requirement is an approximate figure based on an assumed concentrate grade of 5.75 per cent Li2O and a conversion recovery of approximately 86 per cent, and is not a production estimate for the Victory project.

Rock Tech Lithium announces that it has engaged Apaton Finance GmbH of Ellernstrasse 34, 30175 Hanover, Germany, to provide investor relations and promotional services, effective Oct. 22, 2026, for a targeted term of approximately 12 months. The services include the preparation and dissemination of English and German language articles through Apaton's own channels and third party financial news platforms in Germany and North America, participation in on-line investor events and interviews, and continuing market and media monitoring. The company will pay Apaton a total fee of 80,000 euros, plus applicable taxes, in four equal quarterly instalments of 20,000 euros. Apaton will not receive any securities of the company as compensation. Apaton is at arm's length to the company. Apatons managing director directly holds 661,600 common shares of the company and 230,800 common share purchase warrants, each exercisable to acquire one common share at a price of 90 cents until Aug. 21, 2029. To the company's knowledge, neither Apaton nor any of its other principals holds securities of the company. The engagement is subject to the acceptance of the TSX Venture Exchange.

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 per year), and Ontario, Canada ("approximately 30,000 tonnes per annum of lithium salts"), 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 intended to be sourced exclusively from verifiably ESG-compliant suppliers. In Canada, Rock Tech relies, among other sources, on its wholly owned Georgia Lake project, which is intended to provide 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 intends to contribute 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.
