Zulu Lithium Plant Update

Premier African Minerals Limited ("Premier" or the "Company") is pleased to provide a further update on the plant status at the Zulu Lithium and Tantalum Project ("Zulu") following the announcement on 8 August 2025.

Zulu Plant

Primary Flotation Plant

The second phase of the OEM plant test run has now been completed with positive outcomes to the extent that the plant is now able to run continuously as intended and is now commissioned such that all plant components operate and are integrated and automated to support the ongoing optimisation necessary to continuously meet saleable concentrate grade. Both the OEM and Zulu are satisfied with the significant progress made.

Saleable concentrate requires a spodumene concentrate with more than 5% Li2O ("Saleable Concentrate"). The plant at Zulu has achieved Saleable Concentrate on numerous occasions with grades up to 6,2% Li2O, and the result of ongoing optimisation is expected to be that this is achieved consistently.

While the operations of the Primary Flotation Plant will involve ongoing optimisation as would normally be expected with any producing plant, we are now reassured that the process has moved from a commissioning phase to that of a refining and optimising phase as we now look forward to the growth and operational chapter of Zulu.

Secondary Flotation Plant

After a review of the performance of the Test Run and the fact that some operating parameters have changed since the test work done last year on the secondary floatation plant, the board have elected to postpone this purchase to allow our newly appointed managing director to fully assess the rationale and benefits of proceeding with this.

Prepayment and Offtake Agreement

On the 23 April 2025 the Company announced that a non-binding letter of interest had been concluded. The large trading house concerned has now conducted a second site visit and has confirmed that the minimum requirements for their purchase of spodumene is Saleable Concentrate. Further updates will follow.

George Roach, CEO commented, "We are pleased with the progress made so far and remain focused on advancing Zulu from its current early stage to the diversified industrial minerals producer we believe it can become. The recent rise in spodumene pricing is encouraging, with the potential to transition Zulu from its current position to sustained profitability. Achieving full optimisation and settling outstanding debt will involve securing additional funding and continuing to apply strong, strategic management.

In this regard, the negotiations outlined in the letter of intent will be important and pivotal. These are expected to commence in the immediate future and we will update accordingly."
