Operational and Corporate Update
Premier African Minerals Limited reports encouraging initial results from its upgraded flotation plant at the Zulu Lithium and Tantalum Project, achieving concentrate grades exceeding 5.0% Li₂O, with peaks up to 5.58% Li₂O, though these are preliminary and internally verified. Commissioning was curtailed by ore feed exhaustion, processing approximately 6,000 tonnes of ore, and the company is focused on rebuilding a ROM stockpile to support a 30-day continuous operating campaign expected to recommence in July 2026. Discussions with Canmax regarding an extension of the Long Stop Date under prepayment and offtake arrangements are positive, with Canmax reviewing operational data. The company is also working towards publishing its audited accounts for the year ended 31 December 2025 by 30 June 2026. Disclaimer*
About this update from Premier African Minerals Ltd.
25 June 2026 Premier African Minerals Limited Operational and Corporate Update Premier African Minerals Limited ("Premier" or the "Company") is pleased to provide an update on the optimisation of the upgraded flotation plant at the Zulu Lithium and Tantalum Project ("Zulu") and on ongoing discussions regarding the extension of the Long Stop Date under the Company's prepayment and offtake arrangements as announced on 5 January 2026. Graham Hill, Managing Director, commented, "The initial results from the upgraded flotation circuit are very encouraging and represent the most positive operating performance we have seen from the plant to date. While commissioning was cut short due to the exhaustion of available ore feed, the circuit demonstrated a significant improvement in concentrate quality and overall operating stability compared to the previous configuration. The immediate priority is to ensure that sufficient ore is available on the ROM pad to support an extended continuous operating campaign. Experience has shown that flotation circuit optimisation requires sustained operation over a prolonged period, and we believe that establishing an adequate stockpile before recommencing commissioning activities represents the most efficient approach. Our objective is to operate the plant continuously for a period of approximately 30 days, which should provide the data and operating experience required to fully optimise the circuit and assess its long-term performance. In parallel, we are engaging constructively with Canmax regarding a further extension of the Long Stop Date. Discussions are positive and Canmax is currently reviewing the latest operational data generated during commissioning. We appreciate Canmax's continued engagement and look forward to updating shareholders as these discussions progress." Operational Performance Initial commissioning of the upgraded flotation circuit has demonstrated encouraging improvements in performance relative to the previous circuit configuration. Based on internal laboratory analyses conducted during commissioning, the upgraded circuit achieved rapid froth formation following start-up and produced concentrate grades materially in excess of those previously achieved. Internal assay results recorded sample concentrate grades exceeding 5.0% Li₂O, with peak sample grades of up to 5.58% Li₂O achieved. As previously repo...
