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.
