Operational Update

Premier African Minerals Limited ("Premier" or the "Company") is pleased to provide a further interim update on the ongoing progress at the Zulu Lithium and Tantalum Project ("Zulu Lithium").

Graham Hill, Managing Director, commented: "We remain firmly focused on progressing commissioning activities in a methodical and disciplined manner at the new Zulu Lithium flotation plant and associated processing circuits, ensuring that, prior to the commencement of final hot commissioning, the Company has appropriately prepared for, planned, and considered all operational scenarios that could reasonably be anticipated.

Following the successful completion of several tests during cold, (wet), commissioning the hot commissioning of the plant has started on ore. Hot commissioning from the crushing plant to the mill and to the mica flotation plant has now been successfully completed. What remains is the hot commissioning of the new spodumene flotation plant and the production of saleable concentrate. The Zulu team are currently working on final planning with the Xinhai Technology commissioning and optimisation engineers in order to achieve this. This has been a significant achievement by the Zulu engineering and processing team of whom we can all be proud.

Progress to date continues to support the Company's previously provided guidance that completion of the current commissioning programme remains on track for the Q2 2026 completion timeline."

Zulu Lithium Operational Update

The Company is pleased to confirm that the mining contractor is ready to mobilise additional mining equipment in order to meet the anticipated ore feed demand requirements associated with planned plant operations.

Installation and testing of the final major mechanical equipment associated with the new spodumene flotation plant, being the plant air blower system, has been completed successfully. The Company has also continued wet commissioning activities across both the new and existing flotation plant, with water circulated continuously through the process circuits during extended operational testing in order to confirm plant flow rates and identify and rectify any potential problems.

The plant Supervisory Control and Data Acquisition control system has also now been successfully re-commissioned and integrated with the modified flotation plant configuration. The Company has additionally continued progressing commissioning activities associated with ore handling and processing systems. Hot commissioning of the plant, on ore, has now progressed to include the milling circuit and the mica flotation section. Planning for hot commissioning of the new spodumene flotation section is well advanced and the Xinhai Technology commissioning and optimisation engineers are now on site as part of this final phase of getting Zulu into production.
