Premier African Minerals Limited (“Premier” or the “Company”), is pleased to report on assay results at Premier’s Zulu Lithium and Tantalum Project (“Zulu”).
· Multiple wide high-grade zones intersected
· Early QXRD data confirms Spodumene as dominant Lithium mineral
George Roach, CEO commented, “The detailed results set out below are impressive. Similarly, the early QXRD work confirms our view that the Zulu deposit is predominately spodumene. Notable is the pervasive Tantalum and Rubidium presence. The results reported on are from boreholes within the existing resource area and are part of the ongoing programme that is intended to upgrade confidence in the original resource estimate from an inferred level to an indicated level. At the same time, we have reviewed all the previous work done prior to January 2022, adjusted the geological model as indicated and we are in the process of revalidating many of the previously obtained assay results. The work to date has provided the level of confidence we needed internally to support the pilot plant concept as recently announced. In fact, what we are now understanding about the Zulu deposit is entirely complementary to the use of sensor-based ore sorting and in time is likely to result in a most efficient and effective process.
It is worth noting that these results below are likely indicative of more than 2,000 outstanding assays now starting to come through. To date since the commencement of the DFS programme, we have completed 82 holes and 18,466 m. Much of the recent drilling has been at close-spaced centres of approximately 50 m and it is this intensity that supports our confidence in this section of the resource. It should be noted that these results are all confined within the original claims area. The deposit remains open on strike in both directions and at depth. The initial QXRD results have highlighted the value of this work providing a better description of the pegmatites and will contribute to future grade control in the pilot plant phase of the Zulu development”.
Drill Holes: Lithium & Tantalum Results
The table below sets out the independent external laboratory analyses for holes ZDD063, ZDD067, ZDD068, ZDD070, ZDD072, ZDD076, ZDD077, ZDD078 and ZDD079.

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.
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.
All samples are crushed and pulverised to 75 microns with 85% of the pulverised sample passing -75microns. Samples are analysed at the SGS Laboratory Services in Randfontein, South Africa as 30-element scans following a sodium peroxide fusion and ICP-OES and ICP-MS analytical finish. (SGS code ICM90A).

About the Geology at Zulu
The area, located in the Fort Rixon Greenstone Belt, is underlain by Archaean-aged meta-volcanics and meta-sedimentary sequences of the Bulawayan System, with serpentinites and banded iron formations at the base in the east and metamorphosed volcanics and sediments 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 up to chlorite facies.
The Zulu Pegmatite is a LCT (Lithium-Caesium-Tantalum) pegmatite swarm which intrudes along the contacts between serpentine and meta-sedimentary rocks over a strike length of several kilometres. Outcrop widths vary between 10 and 25 m. The pegmatite bodies strike N20° and dip with 70° to 90° to the west.
The area was first pegged in 1955 by J.S. Willemse and intensely explored, under an option, with mapping, trenching and drilling by Rhodesian Selection Trust Co. Ltd. (“RST”) in 1958. In 1961 and 1962 a small quantity of petalite was mined by W. Burchett in partnership with J.S. Willemse. Premier later acquired the claims the Zulu in 2013.
The thickest pegmatite, north and south of the Machakwe river, is rich in spodumene, petalite and lepidolite while the thinner footwall pegmatites tend to be lower in Li-grade but carry good tantalum and rubidium grades.
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.
