Zulu Assay Results
Premier African Minerals Limited ("Premier" or the "Company"),
is pleased to report on assay results at Premier's Zulu Lithium and
Tantalum Project ("Zulu"). These results are from boreholes that
are located within the area planned to be mined under operation of
the Pilot Plant and will constitute a portion of the Mineral
Resource update required to support the DFS.
George Roach, CEO commented , "We continue to see good
intersections within the main spodumene rich pegmatite that are
both encouraging for the long term and supportive of our decision
to commence operations with the large-scale pilot plant as we have
done."

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.
Currently, drill core samples are crushed and pulverised at the
Antec Laboratory, Zimbabwe to 85% passing -75 microns. Sample pulps
are inspected for export in Harare by the competent government
authorities and 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.
Recent mapping and interpretation of the pegmatite swarm from
semi-quantitative X-Ray Diffraction (XRD) has identified three
distinct phases of pegmatites. A spodumene-rich, thick pegmatite
named the Main Zone which lies north and south 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.
