Operational Update

Premier African Minerals Limited ("Premier" or the "Company") is pleased to report on the progress of operations at Premier's Zulu Lithium and Tantalum Project ("Zulu").

Preliminary internal laboratory analysis undertaken by Zulu's operational team confirms the presence of spodumene within the concentrate produced to date. These results are preliminary in nature, have been generated by the Company's internal laboratory and should not be regarded as independently verified. Whilst concentrate grades achieved to date remain below target levels, the Company has observed a progressive improvement in concentrate quality as commissioning and initial optimisation activities continue. It is normal during the early stages of flotation plant commissioning for concentrate grades to be below target specification as operating parameters are refined and the circuit stabilises.

Commissioning and optimisation work remain ongoing and while it would therefore be premature to comment on expected recovery rates, final concentrate grade, throughput rates or overall plant performance, the Board is very encouraged by the initial plant performance. The operating team continues to focus on refining reagent additions, flotation parameters and plant stability with the objective of maximising both concentrate grade and recovery. Further updates will be provided in due course as additional operating data becomes available.

Graham Hill, Managing Director, commented, "The production of first spodumene concentrate marks an important milestone in the commissioning of the new flotation plant and provides initial confirmation that the flotation circuit is operating and producing a spodumene-bearing concentrate stream. Based on the operating data accumulated to date, the plant appears to be exhibiting improved operational stability relative to previous operations. This is believed to be attributable to the simplification of the process flowsheet and the modifications implemented across the process plant, although further operating time will be required to fully assess long-term performance.

The production of spodumene concentrate from the modified plant and new spodumene flotation plant represents a significant step forward in the development of Zulu, and I would like to congratulate the Zulu team on achieving this important operational milestone."
