Savannah Resources Plc announced as part of its ongoing work towards a Definitive Feasibility Study ('DFS') on the Project, an upgrade to the JORC 2012 compliant Resource for the NOA orebody together with further results from the current drilling programme. NOA Resource Upgrade: NOA resource upgrade completed following recent drilling with 93% of the total resource now in the Indicated category (previously 67%), increasing the overall geological confidence in the resource and meeting the requirements for inclusion in the DFS. JORC 2012 Compliant Resource now 661,000 tonnes at 1.03% Li2O, containing 6,800 tonnes of Li2O.

The size of the resource has increased by 3% due to extending the mineralisation on the western pegmatite. Further exploration potential outlined to the west, as the pegmatite is still open along strike to the west and at depth to the north. Reservatório and Grandão Significant Drill Results: Assays from 7 diamond drill holes at the Reservatório orebody have now been received, which confirm the lithium mineralisation at depth and the potential for further resource expansions.

The best results received, with key lithium intersections include: 36.48m @ 1.34% Li2O from 31.05m in 23RESDD009. 36m @ 1.28% Li2O from 151m in 23RESRC039. 21.8m @ 1.37% Li2O from 132.3m plus 9.2m @ 1.08% Li2O from 157m in 23RESRC041.

Results received from two Reverse Circulation holes drilled at Grandão at the margins of the pegmatite confirm the continuity of the lithium mineralisation to the north. The best result recorded was: 18m @ 0.93% Li2O from 35m in 24GRARC132. With the completion of resource-related drilling in phase 1 of the current drill programme at the Project, an updated JORC 2012 compliant Mineral Resource Estimation could be made for the NOA deposit.

The purpose of the drill programme was to infill the Project's geological database to classify the resources in the Indicated or Measured categories and to fulfill requirements for the DFS. In addition, further assay results from the recent drilling at Reservatório (7 diamond drill core holes) and Grandão (2 Reverse Circulation ('RC') drill holes) have been received and confirm that the lithium mineralisation is continuing at depth and along strike. NOA: From the results of the drilling at NOA, Savannah's resource consultant has been able to increase the geological confidence of the resource.

Now 93% of the total resource has been classified in the Indicated category (previously 67%). The remaining 7% of the new estimate represents extra tonnes identified in extensions of the pegmatite bodies, particularly at the western end of the deposit area, and is classified in the Inferred category. Reservatório: Preliminary indications are that the dip of the pegmatite is becoming shallower at depth and confirms the extension of the Reservatório mineralisation at least a further 100m down dip, pointing towards a potential extension of the resource.

Key lithium intersections returned in the latest batch of assays include: 36.5m @ 1.34% Li2O from 31.05m in 23RESDD009. 36m @ 1.28% Li2O from 151m in 23RESRC039. 26m @ 0.85% Li2O from 155m in 23RESRC040.

21.8m @ 1.37% Li2O from 132.3m plus 9.2m @ 1.08% Li2O from 157m in 23RESRC041. Drill hole 23RESDD009 was drilled in an area that is representative of the first phase of mining and the samples will also be used for metallurgical testing purposes. Grandão: At Grandão, the results of two RC drill holes have been received.

The holes were planned to test the southern and northern margins of the main pegmatite with only the northern hole (24GRARC132) containing significant lithium mineralisation. The key lithium intersection returned in the latest batch of assays was18m @ 0.93% Li2O from 35m in 24GRARC132. Future Drilling: The second phase of the current drilling programme will target Reservatório, Pinheiro and Grandão to further upgrade the resources at these depositsby the end of Third Quarter 2024.

Details for the second phase of the programme will be finalised once all results from the first phase have been received and reviewed.
