Zulu Lithium Update

The Board of Premier African Minerals Limited ("Premier" or the "Company") is pleased to provide an update on further assay results and current progress on Zulu Lithium and Tantalum ("Zulu").

George Roach, CEO commented : "ZDD162 and ZDD163 are very pleasing results coming from the Southeast zone under development which is not part of the current pit operations. This Southeast zone appears to be Spodumene Quartz Intergrowths ("SQI") dominant with more than 90% of the mineralisation associated with spodumene. ZDD165 is infill from our North pit (Main zone) and supportive of our conclusions to date.

By way of update on the Zulu plant, all components for the thickener are now either at site or on route. The final components and the ball mill are all expected to be loaded for planned departure for site on 29 January 2024. The mill is expected to be factory run on the 26 January 2024 immediately prior to loading."

**0.50% Li2O cut-off applied.

The following compositing routine has been applied:

-- 0.50% Li2O cut-off was applied to the pegmatitic intersections only.

-- <2m standalone composites at the cut-off grade but with an overall weighted average grade of >0.5% Li2O are not reported.

-- Within any composite of >2m thickness, high-grade intersections of 1m and greater are reported provided the high-grade intersection is a multiple of x 1.5 of the overall weighted composite grade, and

-- Within any composite, inclusions of country rock of <2m thickness are included within the composite provided the overall grade of the composite is not <0.50% Li2O.

Quality Assurance/Quality Control (QA/QC)

The drill holes are initially sited using a hand-held GPS (Global Positioning System device) within the tenement areas. Accurate coordinates and elevations of drill holes collars are subsequently derived from a DGPS (Differential Global Position devices) survey upon completion of the drill hole.

Drill cores are geologically logged, intersections of interest are selected are marked-up with unique sample ID assigned before splitting and sampling. Cores are cut in half using a core cutter, individual samples bagged, and sent for analysis.

Alternating Certified Refence Materials (CRM), blank or duplicate samples are inserted every 10th sample into the sample stream sent to the laboratory to ensure QA/QC compliance. These QA/QC samples are assessed upon receipt of analyses, checked and, if acceptable, accepted into the analytical database. Follow-up with the laboratory is instigated in cases were any QA/QC sample fails the QA/QC parameters.

Currently, drill core samples are crushed and pulverised at the Antec Laboratory, Zimbabwe to 85% passing -75 microns. Sample pulps are couriered to the SGS Laboratory Services in Randfontein, South Africa where pulps are fused with sodium peroxide and analysed by ICP-OES and ICP-MS to report 51-elements. (SGS code ICP90A50 & IMS90A50).

The Geology of Zulu

The area, located in the Fort Rixon Greenstone Belt, is underlain by Archaean-aged meta-volcanics and meta-sedimentary sequences of the Bulawayan Supergroup, with serpentinites and banded iron formations at the base in the east and metamorphosed volcano-sedimentary sequences to the west. The greenstone belt is tear drop shaped measuring 30 km long and 19 km wide near the broad section at the top. Metamorphism is retrograded to Greenschist facies.

The Zulu Pegmatite is a LCT (Lithium-Caesium-Tantalum) pegmatite swarm which intrudes along the contacts between serpentine and metamorphosed volcano-sedimentary sequences over a strike length of several kilometres. Outcrop widths vary between 10 and 50m. The pegmatite bodies strike N20deg and dip 70deg to 90deg to the west.

The area was first pegged in 1955 by J.S. Willemse and intensely explored, under option, by mapping, trenching and drilling by Rhodesian Selection Trust Co. Ltd. ("RST") in 1958. In 1961 and 1962 a small quantity of petalite from the River Pegmatites (see below) was mined by W. Burchett in partnership with J.S. Willemse. Premier later acquired the claims in 2013.

Mapping and logging of drill cores within some pegmatites semi-quantative powder X-Ray Diffraction (XRD)a has identified three distinct pegmatite classes in the Mineral claims block. Spodumene-rich, thick pegmatites named the Main Zone (North Pit) , South Pegmatite (South Pit) and SE Zone which are located north, south and SE of the Machakwe River; footwall low-spodumene pegmatites with associated tantalum and rubidium; and a suite of petalite-bearing pegmatites of short strike length, named the River Pegmatites.

In general, the lithium minerals, occurring in varying quantities, are coarse grained with associated feldspars and quartz with only very minor sulphides being observed. In several contact zones, the lithium-bearing amphibole, holmquistite, has been observed.

Qualified Person

Bruce Cumming, a consulting geologist to Premier, has reviewed and approved this release to the extent that reference is made to the geology and mineralogy of the Zulu pegmatites. Mr. Cumming is a SACNASP and GSSA registered geoscientist with 48 years' experience in exploration and project management, in multicommodity projects throughout Africa.
