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

Highlights:

·New flotation cells fully installed, aligned, levelled and connected under supervision of the manufacturer's installation engineer.
·Product and tailings pumps installed on plinths.
·Installation of launders underway with structural steelwork for walkways progressing well.
·Piping crew mobilised with plant integration pipework now commencing.
·Commissioning planning progressing with process engineering team mobilisation initiated.
·Approximately 5,000 tonnes of ore available on ROM stockpile for early commissioning.
·Commissioning and optimisation remain on track for Q2 2026.

Graham Hill, Managing Director, commented: "We are very encouraged by the continued progress being made on site at Zulu Lithium. The installation of the Xinhai Flotation Plant is advancing well and, importantly, in line with our planned timeline. The level of coordination between our on-site team and the manufacturer's engineer has been particularly pleasing and gives the Board confidence as we move towards the commissioning phase.

It is also positive to see the increasing levels of operational readiness, including the mobilisation of the process engineering team and the availability of ore on the ROM pad to support early commissioning activities, utilising material already mined and at no additional mining cost to the Company.

We remain focused on delivering commissioning and optimisation during Q2 and moving the project towards steady-state production of spodumene concentrate.

We would also encourage shareholders to follow the Company's official account on X (formerly Twitter), where we are providing regular photographic updates of progress on site. These updates offer useful visual context to the significant work currently underway at Zulu Lithium and reflect the momentum being built".

Zulu Lithium Operational Update

Installation of the new flotation cells has been completed, with all units now aligned, levelled and connected. This critical phase was undertaken under the supervision of the manufacturer's installation engineer and is essential to ensure effective gravity-driven material flow through the flotation circuit. Following the delivery of materials for the fabrication of structural steel walkways and flotation launders, on-site fabrication by the Zulu Lithium team has progressed well. Installation of the launders is now underway, alongside the erection of supporting steel structures for safe plant access.

The new pumps for both product and tailings streams have been successfully installed on their respective plinths. In parallel, the piping team has mobilised to site and commenced installation of the pipework required to integrate the new flotation plant with existing infrastructure. The motor control switchgear is currently being assembled off-site and will undergo factory acceptance testing prior to delivery. Delivery to site remains on schedule and is expected within the next two weeks.

Operational readiness activities are advancing, including the development of a detailed commissioning plan and the mobilisation of the process engineering team. Discussions are also ongoing with a mining contractor to support appropriate mobilisation planning and ensure continuity of ore supply. The Company currently holds approximately 5,000 tonnes of ore on the ROM stockpile, which will be utilised during the initial commissioning phase, with additional ore to be supplied thereafter.

Commissioning and optimisation during Q 2 2026 remain the target, with the aim of achieving steady-state production of on-spec spodumene concentrate.
