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

Rock Tech Lithium Inc. has completed the first closing of a non-brokered, fully subscribed private placement offering of 7,923,147 units at a price of 65 cents per unit for aggregate gross proceeds of approximately $5.2-million.

Today, in connection with the closing of the first tranche of the offering, Rock Tech issued 2,923,147 units at a price of 65 cents per unit for aggregate gross proceeds of $1,900,045. The company has entered into irrevocable subscription agreements for an additional tranche of the offering, representing gross proceeds of $3.25-million, and expects to complete such tranche on or before Aug. 28, 2026, subject to the satisfaction of customary closing conditions.

More than 60 per cent ($3.25-million) of the offering was subscribed by a new strategic investor, which is concurrently entering into a strategic equity participation at the project level in the company's fully permitted Guben lithium hydroxide converter in Brandenburg, Germany. The investor's decision to also participate in this offering reflects its confidence in Rock Tech's overall asset management strategy. Further details of the Guben transaction will be announced separately after final close of the transaction.

The balance of the offering was subscribed by Canadian investors, including first-time investors in Rock Tech, together with existing shareholders. The company welcomes the further broadening of its Canadian shareholder base as it advances the Georgia Lake mine and the Red Rock converter in Ontario.

The company intends to use the net proceeds raised from the offering to advance the definitive feasibility study for the Georgia Lake mine and the development of the Red Rock converter in Ontario, and for general corporate and working capital purposes.

Each unit consists of one common share in the capital of Rock Tech and one-half of one common share purchase warrant. Each warrant entitles the holder thereof to purchase one common share at an exercise price of 90 cents per warrant share for a period of 36 months following the date of issuance of such warrant, subject to and in accordance with the terms and conditions of the certificate evidencing such warrant, including adjustment in certain circumstances.

In connection with the offering, the company may pay eligible finders a cash commission equal to 6 per cent of the gross proceeds raised from subscribers introduced by such finders and, subject to the approval of the TSX Venture Exchange, may issue broker warrants equal to 6 per cent of the aggregate number of units sold to subscribers introduced by such finders. Each broker warrant will entitle the holder thereof to acquire one common share at an exercise price of 65 cents per common share for a period of 24 months from the date of issuance.

Closing of the offering remains subject to receipt of final approval 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 lithium hydroxide monohydrate per year), and Ontario, Canada (up to 32,000 tonnes lithium carbonate equivalent per year), form the foundation for a stable and regional supply to the battery and automotive industries. The Guben converter has been recognized as a strategic project under the European Union Critical Raw Materials Act.

The raw materials for Rock Tech's converter projects are intended to be sourced exclusively from verifiably environmental, social and governance 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, policy-makers and community groups, and is committed to open communication and the highest environmental standards.
