Savannah Resources Plc

(AIM: SAV) ('Savannah' or the 'Company')

Board Changes

Savannah Resources plc, the developer of the Barroso Lithium Project (the 'Project') in Portugal, one of the European Commission's 'Strategic Projects' under the Critical Raw Materials Act and Europe's largest spodumene lithium deposit, announces two changes to its Board of Directors which reflect the progress made in the Project and preparation for the steps ahead, which include project financing, construction and subsequent operation.

After 12 years of dedicated service on the Company's Board, Mr Dale Ferguson is stepping down from the Board, effective from 7 October 2025. Mr Ferguson is a particularly important person with regards to Savannah's progress at the Barroso Lithium Project, as it was through him that the C-100 concession was transitioned from feldspar to lithium, and it was through his sustained cross-continental efforts that it progressed through the traditional geological de-risking process to the current stage of confirmation of economic value and preparation for project execution. Savannah is pleased to report that Mr Ferguson will remain with the Company as part of its executive leadership team in his current role of Chief Technical Officer, ensuring continuity in the leadership of Savannah's technical team as the Company continues to develop the Project.

In addition, The Board is pleased to confirm that Mr Paulo Pinto, a representative of the Company's substantial shareholders, Grupo Lusiaves SGPS, S.A ('Grupo Lusiaves') and Pluris Investments, S.A.[1] ('Pluris') (the 'Shareholders'), has joined the Board as a Non-Executive Director. Mr. Paulo Pinto is an experienced Board Member and Senior Executive with over 30 years of leadership in the banking and financial services industry. He has served on the boards of multiple financial institutions and currently holds the position of Executive Board Member at Pluris Investments, a diversified investment group based in Portugal. His appointment provides greater connectivity with the Company's significant Portuguese shareholders and increases Savannah's network among key stakeholders in the finance and business sectors within the country.

Rick Anthon, Savannah's Chairman said: "I would like to thank Dale for his long and diligent service as a member of Savannah's Board and I am delighted that he is remaining in his executive role as Chief Technical Officer, leading on the technical aspects of the development of the Barroso Lithium Project as we move into a critical phase on the timeline. The Board retains significant mining and lithium sector experience through Non-Executive Director, Bruce Griffin, and myself.

"I am also pleased to welcome Paulo Pinto to the Board. Paulo brings significant experience in the Portuguese financial sector to the Board, which will complement the recent CFO and Project Finance Manager appointments we made as we prepare for the Project's construction financing phase.

"While we will continue to enhance our team as we move forward, I feel confident that Savannah has the ideal Board and management team today to move the Project through its upcoming milestones."

Paulo Pinto, Savannah's new Non-Executive Director said, "It is a privilege to join the Board of Savannah Resources as a Non-Executive Director at such a strategically significant moment for the Company. Although my professional background lies outside the mining sector, for decades I have followed the construction of industrial businesses in northern Portugal in particular, and I believe this external viewpoint can add value by introducing diverse thinking and independent analysis as the company approaches key decisions in the Project's development.

"My intention is to help with a disciplined, objective lens in Board discussions - supporting the executive team by constructively challenging assumptions, encouraging rigorous evaluation of risks and opportunities, and ensuring that decisions are grounded in long-term value creation and responsible governance. I look forward to contributing to Savannah's ambitions with a strong commitment to transparency, stakeholder alignment, and strategic clarity during this important phase of growth."

About Savannah

Savannah Resources is a mineral resource development company and the sole owner of the Barroso Lithium Project (the 'Project') in northern Portugal. The Project is the largest battery-grade spodumene lithium resource outlined to date in Europe and was classified as a 'Strategic Project' by the European Commission under the Critical Raw Materials Act in March 2025.

Through the Project, Savannah will help Portugal to play an important role in providing a long-term, locally sourced, lithium raw material supply for Europe's lithium battery value chain. Once in operation, the Project will produce enough lithium for at least half a million vehicle battery packs per year and hence ensure that Europe reaches the European Commission's Critical Raw Material Act goal of a minimum 10% of European endogenous lithium production from 2030. Savannah is focused on the responsible development and operation of the Barroso Lithium Project so that its impact on the local environment is minimised, and that its impact on the global energy transition and the socio-economic benefits that it can bring to all its stakeholders are both maximised.

The Company is listed and regulated on the AIM Market of the London Stock Exchange and trades under the ticker "SAV".
