Savannah Announces Advisory Committee to Support the Development of the Barroso Lithium Project

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 is pleased to publicly announce its Advisory Committee, a strategic body composed of highly respected individuals with recognised experience and credibility across a range of fields. The Advisory Committee supports the Company in advancing the Project in Boticas by providing well-founded analysis, recommendations, and guidance to help ensure the Project's success and long-term sustainability.

The members of the Advisory Committee, some of whom have been involved in the Project for several years, were selected for their experience and expertise, playing a key role in strengthening the company's decision-making process. The Advisory Committee is composed of four members, though its composition may be adjusted over time to ensure it continues to reflect a perspective that complements regional development and value creation.

The members of the Advisory Committee are:

·   Luís Mira Amaral. A former Minister in Portugal's Government, academic and business leader across multiple sectors;

·    Luís Amado. A former Minister of State and Foreign Affairs, Minister and Secretary of State in Portugal's Government, academic and business leader in the industrial, energy, and technology sectors;  

·   Carlos Caxaria. A former Vice-President of the Geological and Mining Institute and Deputy Director-General at the Directorate-General for Energy and Geology (DGEG) and business leader in the minerals industry; and

·  Astrid Karamira. A specialist in responsible mineral supply chains and sourcing and international development and Board member of the Global Battery Alliance.

Savannah's Chief Executive Officer, Emanuel Proença said: "The work of the Advisory Committee is of great value to Savannah and to the Barroso Lithium Project. Having individuals by our side with such proven track records across a range of fields is both a privilege and a testament to our commitment to excellence in this Project. We believe that the diversity of backgrounds enriches strategic discussions and helps us anticipate the various challenges and opportunities facing our Project and all those involved in it. The Committee's composition gives us confidence that the positioning of our Project - and the broader lithium value chain we aim to help develop in Portugal - is strengthened by highly qualified and respected perspectives in areas such as reindustrialisation policy and national competitiveness, economic diplomacy, deep knowledge of Portugal's mineral resource sectors, and the integration and value creation of these resources within the global lithium and battery markets."

The Advisory Committee meets regularly with the Company's leadership, and provides a critical, comprehensive, impartial, and experienced perspective that directly contributes to informed decision-making.

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 (contained in c.190,000tpa of spodumene concentrate) for approximately half a million vehicle battery packs per year and hence make a significant contribution towards 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 environment is minimised and the socio-economic benefits that it can bring to all its stakeholders are maximised.

The Company is listed and regulated on the London Stock Exchange's Alternative Investment Market (AIM) and trades under the ticker "SAV".
