Premier African Minerals Limited ("Premier" or the "Company"),
is pleased to report on assay results at Premier's Zulu Lithium and
Tantalum Project ("Zulu").
Highlights:
-- Multiple thick high-grade zones intersected
George Roach, CEO commented , "The results set out below are
again impressive. Notable is the continued 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 and adjusted the geological model as indicated. 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 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 table below sets out the independent external laboratory
analyses for holes ZDD033, ZDD034, ZDD035R, ZDD036, ZDD022 and
ZDD060.
Holes ZDD033 and ZDD034 (as announced on 7 February 2022) and
ZDD035R and ZDD036 (as announced on 21 February 2022) have been
restated to ensure consistency in the reporting methodology in line
with the announcement on 1 July 2022.

*Not True Width but lineal width
**0.50% Li(2) O cut-off applied.
The following compositing routine was applied:
-- 0.50% Li(2) O cut-off was applied to the pegmatitic intersections.
-- <2m standalone composites at the cut-off grade but with
an overall weighted average grade of >0.5% Li(2) O are not
reported however;
-- Within any composite >2m thickness, high-grade intersections
of 1m are reported, 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% Li(2) O.
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 10(th) 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).
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 up to Greenschist 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 N20deg and dip with 70deg to 90deg 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.
