Savannah Resources plc

("Savannah" or the "Company")

Result of RetailBook Offer

RetailBook Offer and Additional Subscriptions increase total Fundraise to £9.8 million

Savannah Resources plc (AIM: SAV), the European lithium development company, announced on 6 November 2025 the launch of a fundraising comprising a Placing and Subscription in conjunction with a RetailBook Offer.

The Company is pleased to announce that the RetailBook Offer successfully completed and closed at 12.00 p.m. today and that it has conditionally raised £453,647 through the issue of 12,260,733 new Ordinary Shares at the Issue Price of 3.7 pence per share ("Retail Offer Shares").

As a result of the RetailBook Offer, certain Subscribers have increased their participation in the Subscription ("Additional Subscription") in order to ensure that their percentage shareholdings in the Company are maintained on completion of the Fundraise ("Additional Subscription Shares"). Hence, substantial shareholders, Grupo Lusiaves SGPS, S.A. and Pluris Investments S.A., have purchased 1,533,043 and 1,532,661 Additional Subscription Shares respectively.

In total, the Subscription has raised £3,472,998 million through the issue of 93,864,824 Subscription Shares (inclusive of the Additional Subscription Shares).

Consequently, in aggregate, 264,778,598 new Ordinary Shares will be issued pursuant to the Fundraise, being the total of the Placing, the Subscription, the RetailBook Offer and the Additional Subscription, raising total gross proceeds of £9.8 million (US$12.7 million). This gives the Company total cash reserves of approximately £21 million (circa US$27 million) following the Fundraise.

Savannah's Chief Executive Officer, Emanuel Proença said: "The team and I are very appreciative of the level of interest shown in the fundraise by hundreds of new and existing private investors through the RetailBook offer. As many of us within Savannah are shareholders ourselves, we fully appreciate the responsibility placed on the Company by those choosing to make a personal investment in this Fundraise.

"We view the broad diversification in our shareholder base, which spans institutional and private shareholders across multiple countries, as a great benefit to Savannah and reflective of the widespread interest in the development of the Barroso Lithium Project (the 'Project') in support of the energy transition. We are committed to creating value for all our shareholders through the delivery of the Project.

"The £0.5 million invested through the RetailBook offer takes total gross proceeds from this exercise to £9.8 million (US$12.7 million) and our overall cash position to approximately £21 million (circa US$27 million). With this money, we have the financial strength to power forward with the Project over the months ahead. During that period, we will purchase the Aldeia Mining Lease, complete the Definitive Feasibility Study ('DFS') and environmental licence process and lay the foundations for the key workstreams which will define the 'post-DFS' period, as we shift our focus to project finance, further strategic partnering and construction.

"With the Fundraise exercise now successfully completed and spodumene concentrate prices back over US$1,000/t again, all our efforts will be refocused on the Project. We look forward to updating all our shareholders with regards to the value creating goals we have set ourselves."

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.
