Savannah's Chief Executive Officer, Emanuel Proença said: "We are delighted and humbled by the support shown in Savannah's ongoing development of the Barroso Lithium Project by existing and new shareholders alike through this Placing and Subscription. Coupled with our existing cash resources, this modest but important fundraise gives Savannah a financial position of significant strength. As a result, we can continue to move ahead at speed with our development of the Project.

"My sincere thanks go to all those who have participated in this financing and shown their support for both Savannah and, in turn, Europe's wider efforts to execute its energy transition. The contribution from our four largest shareholders is greatly appreciated and clearly demonstrates their ongoing strong support for Savannah and the Project. We are also pleased to have received significant investment from Portuguese institutions, which further highlights the strong domestic support which the Project enjoys. Savannah is also delighted to welcome a number of new institutional investors onto our register from France and UK, which includes sector specialists. This multinational interest in the Project underlines the international efforts which are being made to expedite its development.

"Retail shareholders still have the opportunity to invest alongside these institutions through the separate offer announced yesterday, the result of which will be announced next week.

"This addition working capital will help us to progress work on multiple fronts which will feed into the current Definitive Feasibility Study and into our ongoing preparations for post-DFS workstreams. These include obtaining finance for the Project's construction, continuing to secure land associated with the Project, and further enhancing our team.

"With our financial position significantly strengthened, we look forward to updating all our shareholders, new and existing, with regular news on the Project's ongoing development as we seek to establish ourselves , and Portugal, as a long term, responsible producer of lithium raw material for Europe's battery value chain."
