Talisman Metals PLC ("Talisman" or the "Company") announces the publication of its Annual Report and Audited Financial Statements for the year ended 31 December 2025 (the "Accounts"), which are available on the Company's website www.talismanmetalsplc.com. Additionally, a copy of the Accounts is being posted to Shareholders.

Contained in Appendix 1 to this announcement are the unaudited interim accounts for Tadeen International Limited ("Tadeen") for the 6 months ended 31 December 2025, following the acquisition of Tadeen by Talisman as completed on 27 January 2026.

CEO letter

Tim McCutcheon, Talisman's CEO stated "Dear Shareholders, Colleagues and Stakeholders, 2025 was a truly transformational year for Talisman Metals PLC, where management took all the steps to navigate the change of business, AIM readmission, fund raising and accounting requirements to become what we are today - a focused copper exploration asset developer with projects in Morocco. This process took longer than expected due to the transaction complexity. However, due to the perseverance of management, and with support from our directors, we were able to finish out all the work right in time for the New Year! I wish to say "Thank you" to all the people who helped make this possible.

Morocco as a jurisdiction to work in, is one of the best I have seen in my career, with a fresh mining code, a supportive government, and people who truly want to see the mining sector succeed in their country. Copper as an exploration and development target, is one of the best in the mineral business. Looming supply issues and robust projected demand due to AI power needs, electric cars, and power grid build-out all point to a bright future for copper prices. This backdrop is systemic, meaning its conditions will be in place for a long time and presents a constant tailwind to Talisman as we advance our projects forward.

For 2026 we are rapidly building-out our capacity to work in the field by establishing relationships with contractors and partners, as well as bringing new talent onto the Talisman team. As I write this, the first work at our Fougnar and Tirzzit projects has been completed and results announced. We will continue our work through to the end of the year with the goal of publishing a Mineral Resource Estimate at both projects.

On the capital markets, we are still a new company working to get recognition. In parallel with getting operational results, management is raising the awareness of Talisman amongst a broad investor audience so that our operational success can be best reflected into our valuation. This work never ends and I encourage the reader to feel free to reach out to management with any questions - information flow is the best friend of success on the capital markets!

In summary, 2025 was a transformational year and 2026 shows no signs of slowing down for us. However, Talisman is well worth the effort, as we have a very special group of people and assets to build a true legacy. Thank you for your attention and support. Sincerely, Tim McCutcheon"
