Zulu Lithium Plant Update

Premier African Minerals Limited ("Premier" or the "Company") is pleased to provide an update on the plant status and flotation plant test run at Zulu Lithium and Tantalum ("Zulu") following the installation of spodumene float section inserts and the subsequent plant test runs undertaken during July 2025.

On Tuesday, 22 July the float plant OEM commenced with a planned five days of plant operations intended inter alia to establish ongoing stable plant operations ("OEM Test Run"). The Company is pleased to report that with particular reference to the spodumene float section that has been the last section to be fully completed and optimised, we are now able to report extended running time without interruptions related to the plant and consistent production at saleable grades in excess of 5% spodumene during those periods. At the same time, extensive test work now able to be conducted during real time operations has allowed the OEM to identify other areas not yet fully optimised and to demonstrate the quality of the ore body at Zulu and the amenability to spodumene concentrate recovery through floatation.

The plant OEM and the reagent supplier have been able to identify specific reasons for Zulu's previous experienced poor recoveries and grade. At this time, we believe that certain operational changes, particularly related to improved management of particle size in the comminution circuit, could effectively address this and some contamination issues. It has therefore been decided that the OEM should continue with this test programme for a further five-day test run to implement the identified operational changes and to further examine options to optimise reagents. The start date of next five-day programme is currently being agreed between Premier and the OEM, however the intention is to action the test run as soon as possible.

George Roach, CEO commented," Our knowledge of the plant and our understanding of the complexities of the process and the solutions will support the long-term success of this project. Particularly pleasing is the quality of the resource at Zulu, the fact that this is primarily a spodumene deposit without petalite and the amenability to recovery through floatation.

The ore body has once again demonstrated its ability to produce spodumene concentrate during the past week and we look forward to further advancements in production from next week."
