RHA and Zulu Update

Premier African Minerals Ltd ("Premier" or the "Company"), is pleased to provide an update on RHA Tungsten Private Limited ("RHA") and Zulu Lithium Private Limited ("Zulu").

Premier has completed a new conceptual underground Conceptual Mine Plan for RHA ("Conceptual Mine Plan") in conjunction with technical assistance from independent South African mine planning consultants, Bara Consulting (Pty) Limited ("Bara Consulting"), geological consultants Shango Solutions ("Shango") and metallurgy and process engineer Multotec Process Equipment (Pty) Limited ("Multotec").

This Conceptual Mine Plan has been based on a revised RHA underground Mineral Resource estimate relating to the parts of the ore body included within the Conceptual Mine Plan. The objective of the new Conceptual Mine Plan is to assess the potential impact of returning RHA to production and assess whether RHA can generate a return on Premier's investment to date in surface infrastructure, plant and equipment at RHA at minimal additional capital costs, based on using just the existing vertical access shaft (the previous study had included the construction of a new high-capacity decline shaft). 

The Conceptual Mine Plan assesses an underground production rate of 6,000 tons per month with a projected life of mine of 10 years and indicates a peak funding requirement of US$2.5 million and a payback within 16 months. As Premier has resolved not to commit further funding to RHA, the new funding would need to be provided by a third party (being either the National Indigenisation, and Economic Empowerment Fund ("NIEEF") or another party).

The drilling programme has commenced at Zulu and, despite delays caused by increasing Covid-19 infections in Zimbabwe and Government action in controlling the spread of the virus, the Company remains on track with its plans to prepare Zulu's Definitive Feasibility Study in line with previously reported timelines. 

George Roach CEO, commented, "Surging Covid-19 in the SADC region is not helping at Zulu where travel and other restrictions are impacting the drilling programme. Despite this, the rigs continue to operate and our lab equipment is now only awaiting import clearance to Zimbabwe. The drilling is underway at Zulu and is just one component of the Definitive Feasibility Study. In the background important other work is underway including that associated with environment, water management, tailings management, geotechnical assessment, preparation for additional metallurgical studies, logistics route planning and cost estimates. At this time, Premier still expects to complete the study within the anticipated timelines and a variation to that will be communicated if necessary. In the light of surging spodumene concentrate prices, we have also commissioned a review of the Zulu Scoping Study (RNS 20 November 2017) with the intention of both better understanding the overall potential value of Zulu and to assess potentially reversing the current impairment of this project.

Separately, we are pleased to be able to provide a preliminary update on the process test work and analysis of bringing RHA back to production based on that part of the underground Mineral Resources which we believe can be cost effectively included in the mine plan at the current proposed 6,000 ton per month. The next steps for RHA include negotiations with our 51% shareholder, NIEEF, to explore alternatives to bring this mine back to production. It is worth noting that there remains continued interest from off-take partners in RHA supported by the current APT price. Premier's historic commitment to RHA needs to be matched by NIEEF or another funding option will need to be sourced given there will be no further financial commitment from Premier apart from the basic care and maintenance costs.

The Conceptual Mine Plan is based on an underground production rate of 6,000 tons per month and indicates a peak funding requirement of US$2.5 million and a payback within 16 months. A return to production at this throughput level will make the need for the XRT redundant, and we are already in discussions with other parties in regard to alternative deployment of the XRT.

In the context of this announcement, it is important to note that RHA is a developed mine with existing surface plant and infrastructure already paid for in full by Premier. Recovery of wolframite from the deposit at RHA has already occurred and historically, concentrate produced through the plant at the mine has all been sold and remains in strong demand."

Conceptual Mine Plan

Bara Consulting has prepared a new mine plan to support a production rate of 6,000 tons per month and which would support a projected life of mine of 10 years.

Separately, Multotec, manufacturers of concentration systems including spirals and cyclones, and who supplied the spiral systems already installed at RHA, conducted test work on a bulk wolframite ore sample from RHA to re-assess and optimise the spiral recoveries and water management at the plant. Bara Consulting has reviewed Multotec's test results and has proposed, in consultation with Premier, certain changes to the flow sheet.

Premier has internally completed an updated economic assessment based on Bara Consulting's mine plan and recommended flowsheet changes, and Multotec's test results, to analyse the illustrative costs and returns of a potential return to production based on underground Mineral Resources only. Premier provided all input operating costs and the resultant illustrative internal cash flow budget was modelled in conjunction with Bara Consulting based on underground mining only at 6,000 tonne of Run of Mine ore per month for a projected life of mine of 10 years.

Shareholders should note that the Conceptual Mine Plan is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorised as Mineral Reserves. The Conceptual Mine Plan is based on low-level technical and economic assessments and is insufficient to support estimation of Mineral Reserves or to provide assurance of an economic development case at this stage, or to provide certainty that the conclusions of the Conceptual Mine Plan will be realised. Furthermore, whilst Bara Consulting has reviewed Premier's operating cost assumptions, Bara has not assessed other prerequisites to constitute a Preliminary Economic Assessment. These include tailings management, environmental impacts.

RHA Underground Resource Estimate

Subsequent to the Company announcement In October 2018, when the Company considered alternatives that included the construction of a high-capacity decline shaft to access underground ore with complimentary mining at a rate of 6,000 to 7,000 ton per month for 15 months during construction of the new decline shaft, the Company has reviewed the underground Mineral Resources that would be available to a Conceptual Mine Plan restricted to vertical shaft access only through existing infrastructure. In respect of this new Mineral Resource estimate, Shango has provided an independent audit for technical assurance and reporting compliance of the RHA resource estimate prepared by Mr Gerard Evans, who has acted as the Competent Person responsible for this resource estimate. The updated Mineral Resource estimate, which is compliant with the South African Code for the reporting of Exploration Results, Mineral Resources and Mineral Reserves (The SAMREC Code) 2016 Edition, has assumed that the XRT sorter is no longer used at this reduced tonnage and therefore a cut-off grade of 1.87kg/t has been applied.

The updated underground Mineral Resource estimate is set out in the Table 1 below (and for information only, the previous 2017 Mineral Resource estimate based on whole RHA ore body is set out the Appendix to this announcement). The Mineral Resource estimate set out in Table 1 below is prepared in accordance with the SAMREC Code and in compliance with Appendix 3 of the AIM Note for Mining and Oil & Gas Companies - June 2009).

Table 1: Summary of the Mineral Resource Statement by Resource Category (July 2021)

Notes:

1.    Premier is the operator of RHA. Premier holds a 49 per cent. interest in RHA. RHA is indebted to Premier in excess of US$20m and until such time as this is settled, all concentrate produced will be attributable to Premier.

2.    Mineral Resources are reported in accordance with the SAMREC Code guidelines. Mineral Resources are not Mineral  Reserves and do not have demonstrated economic viability.

3.     A cut-off grade of 1.87kg/t has been used applying a tungsten price of US$300/10kg of WO3 in concentrate.

4.  The Mineral Resource Estimate is based on information compiled by Mr Gerard Evans, reviewed by Shango  Solutions,   with an effective date of 20^th May 2021.

5.     All Mineral Resources reported exclude regional pillars, safety pillars and shaft pillars.

6.   Geological losses of 5% have been applied to the Indicated Resource Category, and 10% has been applied to the  Inferred Resource Category.

7.    The contained WO3 metal values are rounded, actual grades and contained metal kg are accurately stated and any differences in the total are due to rounding.

8.    The W03 in Kg/t is stated as a weighted average grade.

The key financial metrics of the Conceptual Mine Plan are set out below in Table 2 below:

Notes:

1.     Values extracted from Conceptual Mine Plan have been rounded to the nearest whole million.

Mineral Reserves and Mineral Resources

The Company estimates and discloses Mineral Reserves and Mineral Resources using the definitions adopted by the SAMREC Code.  Further details are available at www.samcode.co.za/samcode-ssc/samrec.  See the "Glossary of Geological and Mining Terms" for complete definitions of Mineral Reserves and Mineral Resources.

About Mineral Resources

Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability but do have reasonable prospects for eventual economic extraction.  They fall into three categories: Measured, Indicated, and Inferred. The reported Mineral Resources are stated inclusive of Mineral Reserves.  Measured and Indicated Mineral Resources are sufficiently well-defined to allow geological and grade continuity to be reasonably assumed and permit the application of technical and economic parameters in assessing the economic viability of the Mineral Resource. Inferred Mineral Resources are estimated on limited information not sufficient to verify geological and grade continuity or to allow technical and economic parameters to be applied.  Inferred Mineral Resources are too speculative geologically to have economic considerations applied to them. There is no certainty that Mineral Resources of any category will be upgraded to Mineral Reserves.

Important Information about Mineral Reserve and Mineral Resource Estimates

Whilst the Company takes all reasonable care in the preparation and verification of the Mineral Reserve and Mineral Resource figures. the figures are estimates based in part on forward-looking information. Estimates are based on management's knowledge, mining experience, analysis of drilling results, the quality of available data and management's best judgment. They are, however, imprecise by nature, may change over time, and include many variables and assumptions including geological interpretation, commodity prices and currency exchange rates, recovery rates, and operating and capital costs. There is no assurance that the indicated levels of metal will be produced, and the Company may have to re-estimate the Mineral Reserves based on actual production experience. Changes in the metal price, production costs or recovery rates could make it unprofitable to operate or develop a particular deposit for a period of time.
