Premier African Min (AIM:PREM) 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.”

*Not True Width but drilled width

**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.

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 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 N20° and dip 70° to 90° 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.
