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

Dismissal of Legal Claim

Dismissal of another legal claim made in relation to the Project

Savannah Resources Plc, the developer of the Barroso Lithium Project in Portugal, a 'Strategic Project' under the European Critical Raw Materials Act and Europe's largest spodumene lithium deposit (the 'Project'), is pleased to provide an update on another positive legal judgement made recently in relation to the Project.

The Administrative and Tax Court of Mirandela has dismissed the case brought by the Parish Council of Covas do Barroso (the 'Parish Council') in April 2023 (see 5 April 2023 RNS) against the Ministry of Environment, in which Savannah was named as a counterparty. The claim aimed to have the 2016 Barroso Mine Concession Agreement (the 'Concession') annulled.

The Court's ruling confirms unequivocal validity and conformity of the Concession. The claimant has the option to appeal to the Central Administrative Court.

This decision represents the eighth consecutive positive judgment for Savannah out of eight total decisions made across initial court rulings, appeals and injunctions (See Table 1 for further details).

There are now four[1] remaining ongoing court cases in relation to the Project (see table 3 below for further details). None of the four cases affect Savannah's progress with the Project. In two of the cases, the legal opinions state that they are, like the cases which have been dismissed, without merit.

The third case relates to disputed borders on small packages of land (8 hectares in total) purchased by Savannah from private landowners ('Land Borders Dispute', see table 3 below for further details and 25 July 2022 RNS). The impact of a possible ruling against the landowners involved would be likely limited to minor revisions to the borders of the land involved. If this occurred, it would have no material impact on the development of the Project.

The remaining case is a claim submitted by Savannah against the Covas Baldios, where Savannah requests acknowledgement that it has been fulfilling all its legal and contractual obligations in the lease of a portion of the Baldios property, located in the NOA area, currently under exploitation.

Savannah's Chief Executive Officer, Emanuel Proença, said, "We welcome the clear judgement made by the Court in this case, which reiterates the strong legal framework which underpins our Project. It is a shame that we have to go through these baseless cases, which are consistently brought by the same small group of claimants, which, we believe, do not represent the views of all local stakeholders. However, we must accept the right to opposition, even when it is used inappropriately, and could potentially result in legal consequences for the claimants. It is good to see that with each decision the confirmation of the merits of our team's work to date is further reinforced.

"As stated previously, we know that we face strong scrutiny, and for that reason we are even more diligent in our efforts, which is in itself a reassurance for all our shareholders. Savannah continues to advance the Project with confidence and determination, and with a firm commitment to the strict legality of all processes and operations it carries out."
