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 and was approved for a Portuguese State development Grant of up to €110m in January 2026.

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.183,000tpa 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 AIM Market of the London Stock Exchange and trades under the ticker "SAV".
