Anthony Viljoen (CEO) commented:
"I am delighted to present the preliminary economic assessment for Phase 2 at
our flagship Uis asset in Namibia. This PEA shows outstanding economics and
returns for the expansion and allows us to move forward with excitement to a
full bankable feasibility. The fact we have successfully brought phase 1 into
production allows us to significantly de-risk phase 2 from the considerable
learnings in building a new mine. Phase 2 will see AfriTin produce globally
significant volumes of tin, lithium and tantalum which are vital in meeting
the demands of the transition to a new efficient greener technology future."
Background to the PEA
The historic Uis Mine in Namibia was owned and operated by ISCOR between 1958
and 1991 as a tin mine. AfriTin set out to re-establish the operation in two
phases: Phase 1 is a low capital, cash generating initial production facility,
serving as a pilot for Phase 2, which is planned as a scaled-up version of the
initial phase. Both phases also aim to exploit the tantalum and lithium
by-product potential of the deposit. The Company has successfully established
the tin producing circuits of Phase 1, with the by-product circuits currently
in the design and testing stages. This puts the Company in a position to
proceed with a feasibility study for the ultimate Phase 2, of which the PEA
represents the first step.
Summary of Phase 2 Project Economics
The salient results of the Base Case of the Phase 2 PEA, including tin,
lithium and tantalum, are presented in Table 1.
Table 1: Summary of Economics (Base Case)
NPV (after tax, 8.0% real WACC) US$2.10 billion

Sensitivities
The sensitivity of the project economics to commodity prices was tested for
Low and High price scenarios, in addition to the Base Case assumptions.
Table 2: Project sensitivity to commodity prices (nominal, 2025 forecast)
Parameter Low Base Case High
Tin Price 30,000 40,500 * 50,000
Petalite Price 800 1,150 ** 1,600
Tantalite (Ta(2)O(5)) Price 180,000 240,000 *** 300,000
NPV (after tax) US$1.12 billion US$2.10 billion US$3.01 billion
IRR (after tax) 49% 75% 94%
* Bloomberg Consensus Pricing (11 April 2022) - 2025 forecast (nominal)
** Wood MacKenzie February 2022 Quarterly Update - 2025 forecast (nominal)
*** Roskill Tantalum Outlook to 2029, 15(th) Edition - 2025 forecast (nominal)
Whilst the Directors believe these assumptions to be reasonable based on
informed forecasts and trends it is nevertheless noted that (i) the valuation
of the Uis project is particularly sensitive to the price of tin - the current
tin price of US$43,949 per tonne is at a historic high; therefore there is no
guarantee that the tin prices quoted here will be achieved; and (ii) not all
the resources which form the basis of the assumptions are part of a JORC
compliant resource update. Further information is provided below.
The sensitivity of the Phase 2 project economics was also tested for the
exclusion of by-products, for the following three scenarios:
Table 3: Project sensitivity to the exclusion of by-products
Parameter Tin Only, No By-Products Tin, & Lithium By-product Tin, & Lithium By-product & Tantalum By-product

IRR (after tax) 40% 72% 75%
Project Development Planning
The project development programme for the Uis Phase 2 project consists of the
following planned work streams:
· Metallurgical test work related to the potential lithium and
tantalum by-products;
· Exploration drilling with an ambition to expand the
JORC-compliant mineral resource estimate and increase the geological
confidence for by-product elements;
· Feasibility studies including scoping analysis, trade-off
analysis and refinement to bankability stage; and
· Board approval for the the construction and commissioning of
Phase 2 mining and processing facilities upon the successful completion of
feasibility studies and associated project financing.
Metallurgical Test Work
The metallurgical and cost performance of the current tin producing operation
provides a definitive input for the tin related aspects of the feasibility
study for Phase 2. However, the Company is conducting a comprehensive test
work programme for the potential lithium and tantalum by-products, and new,
complementary technologies. The test work consists of off-site research and
development by reputable service providers, and on-site bulk test work using
pilot plant facilities.
Test work for a lithium product in the form of petalite concentrate is in
progress with FT Geolabs (South Africa), Nagrom (Australia) and Anzaplan
(Germany). In parallel, the Company intends to appoint an EPCM contractor for
the construction and commissioning of a bulk test facility at Uis, to enable
the pilot production of a 4.0% Li(2)O petalite concentrate that could
potentially be sold into both the technical market (glass/ceramics) and the
chemical market (converters to lithium carbonate/hydroxide).
Test work for the production of a tantalum concentrate is in progress with
LightDeepEarth (Pty) Ltd (South Africa) and AfriMet Resources AG
(Switzerland). The results of this work will inform the construction of a
potential tantalum separation circuit at Uis.
Sensor-based ore sorting has been identified as a concentration technology
with the potential to transform the capacity and cost base of processing
facilities at Uis for tin, tantalum and lithium. Ore sorting can potentially
pre-concentrate dry, coarsely crushed ore by two to four times the run-of-mine
grade. AfriTin is collaborating with Steinert GmbH (Germany) to test and
develop the metallurgical parameters as input to the feasibility study. In
addition, the Company intends to appoint an EPCM contractor for the
construction and commissioning of a bulk test facility at Uis, enabling the
pilot production of both a tin/tantalum and lithium pre-concentrate.
Exploration programme
An exploration drilling programme is currently underway at Uis with the aim of
expanding the mineral resource for tin over fourteen additional, historically
mined pegmatites, all of which occur within a five km radius of the current
processing plant. Further work is required to achieve a mineral resource
target of 200 Mt of ore, which we believe is possible based on our knowledge
of the area and the historic work already undertaken. The company has planned
and is executing a full exploration drilling requirement of 150,000 m that
will run concurrently with ongoing operations and feasibility studies. The
programme aims to confirm the historical drill hole database for tin over the
additional pegmatites and provide infill drilling data for the expansion of
lithium and tantalum mineral resources.
Funding Strategy
The development of the Uis Phase 2 project is underpinned by the Company's
technical, financial and managerial capability built up through the operation
of the Uis Phase 1 project. The current Phase 1 operation produces
approximately 850 tpa of tin concentrate, resulting in revenues of
approximately US$20 million pa and an EBITDA of approximately US$10 million
pa.
The Company believes that the expansion of Uis Phase 1, as set out in the
announcement of 6 April 2022, can further enhance the cash generating
capability of the Phase 1 operation. Table 4 sets out the EBITDA potential for
the various stages of expansion of Phase 1, as well as for Phase 2.
Table 4: Project milestones for Uis and projected EIBTDA impact
Phase Milestone Potential Commissioning Date Potential EBITDA (US$ pa)
Phase 1 Crushing Circuit Expansion Q4 2022 US$20 million
Ore Sorting Implementation Q4 2023 US$50 million
By-product Implementation Q2 2023 US$100 million
Phase 2 Ultimate Phase 2 Implementation 2026 US$620 million
The funding of the Phase 2 project will be determined by the Company and its
Directors in due course but is likely to be derived from operational cash
flows generated from the Phase 1 operation (Table 4), from project debt
financing and/or a strategic equity component.
Mineral Resource
The mineral resource target for Uis Phase 2 consists of a JORC-compliant
resource estimate of 72.54 Mt (see announcement dated 19 September 2019), the
details of which are set out below; estimates are based on historical drill
hole data (non-JORC-compliant, produced by ISCOR from 1958 to 1991) and
internal estimates based on modelling of extensions to known pegmatites
(non-JORC compliant).
A mineral resource estimate (MRE) for the V1/V2 pegmatite orebody has been
reported by CSA Global in accordance with the JORC Code (2012 Edition) (see
Appendix A below and the announcement dated 16 September 2019). The mineral
resource has been reported above a cut-off of 0.05% Sn on 16 September 2019.
Exploration targets for the other pegmatites proximal to V/V2 have been
defined by the Company and are included in Table 4. Combined with the existing
MRE, the total mineral resource target amounts to more than 200 million tonnes
of ore. However, the non-JORC compliant resource and the Company's internal
estimates, which are also not JORC compliant, are still subject to
verification, validation and external review; accordingly, such numbers are
provided for guidance only. There can be no guarantee that the final
JORC-compliant resource estimate will reconcile with these early-stage
calculations.

Geology and Mineralisation
The mining licence ML 134 is approximately 200 km(2) in size and includes a
large portion of a Sn-Nb-Ta type pegmatite swarm in the Uis area. The
pegmatites are granitic in composition and are homogeneous intrusions without
prominent mineral zonation. Mineralisation in terms of Sn, Ta and Nb is
generally associated with alteration zones known as greisens and saccharoidal
aplitic units. In addition to the Sn and Ta mineralisation within the Uis
swarm, lithium phases have also been identified in the form of lepidolite,
petalite, eucryptite and cookeite. On ML 134 the primary lithium mineral is
petalite.
Mining
Mining will consist of conventional open pit methods employing low carbon
truck and excavator combinations and is planned to take place over multiple
pegmatite ore bodies from four to five pits concurrently. The total non-JORC
compliant mining reserve (provided for guidance purposes only) is 134 million
tonnes of ore, which could result in mine life of 14 years. The mining plan
features a production rate of 10 Mtpa ROM ore at an average overburden
stripping ratio of 2.6.
Metallurgy and Processing
An intensive ongoing test work programme in conjunction with the established
Uis Phase 1 processing operations is underway to increase the level of
confidence in the selected testing of processing technologies for production
of saleable tin, tantalum, and lithium concentrates. For the production of tin
the Phase 1 operation serve as a proof-of-concept for the larger scale Phase 2
development.
For Phase 2 the beneficiation process may involve dry crushing of the ROM ore
and the use of sensor-based ore sorting once confirmed through test work.
The pre-concentrates from this process could then be treated through various
wet concentration circuits to produce saleable concentrates.
The tin and tantalum minerals could be pre-concentrated by employing x-ray
transmission (XRT) ore sorting and concentrated through dense medium
separation (DMS), gravity separation and magnetic separation. The lithium
mineral petalite could be pre-concentrated through near-infrared (NIR) ore
sorting, concentrated through DMS and cleaned through milling and flotation.
The following overall processing plant recoveries have been modelled in the
PEA:
Table 6: Overall processing plant recoveries.
Commodity Overall Processing Plant Recovery
Tin 70%
Lithium* 30%
Tantalum* 20%
* These by-products are not currently in production; figures based on
metallurgical test work and theoretical process modelling.
A zero effluent plant is planned to include dewatering systems for all
concentrate and discard streams to aim for maximum water conservation and
eliminate the need for tailings dams. Dry tailings will be co-disposed with
course plant discard onto a discard dump.
Bulk Infrastructure
Uis is connected to the main industrial centres by road. Gravel roads are
regularly maintained and are suitable for heavy transport. Imports from South
Africa are by road via Windhoek. The nearest port is Walvis Bay (230 km away).
The intention is that all goods and products will be handled through this
port. The port infrastructure is considered by the Directors to be of a high
standard with capacity for container handling and bulk materials export.
The total estimated water supply for ore processing and domestic use for the
project is 1,350,000 m(3) pa. The Directors consider the Erongo desalination
plant between Swakopmund and Henties Bay on the west coast of Namibia to have
sufficient capacity to supply water to the project. An existing pipeline
delivers desalinated water to the Orano Mining facility at Trekkopje, where
offtake is available for supply to Uis by way of a new pump system and
pipeline. The feasibility study for Phase 2 will also investigate alternative
water supply solutions, including a standalone desalination facility at the
coast 110 km away. The Company is employing infrastructure specialist advisory
Bigen to assist with technical and financial studies, including the
exploration of alternative funding and offtake models.
A connection to the national power grid is planned for the Uis Project with a
new feeder connected to the southern grid at a NamPower substation located at
Trekkopje, due south of Uis. The estimated future demand for Uis is 40 MVA.
The Phase 2 feasibility study will also explore alternative power
infrastructure solutions, including a standalone renewable energy option, and
alternative funding and offtake models.
Product Offtake
AfriTin has established an offtake agreement (valid until 2023 with the option
to renew) for tin concentrate with the Thailand Smelting and Refining Company
Ltd (Thaisarco), located in Phuket, Thailand. Thaisarco is one of the main tin
smelting and refining companies outside China. The agreement, in place since
2019, provides for the sale of concentrate from Uis Tin Mining Company (the
operational entity) directly to Thaisarco.
AfriTin has an established offtake agreement with AfriMet for all the tantalum
concentrate produced. The agreement, in place since 2021, provides for the
sale of tantalum concentrate from Uis Tin Mining Company (the operational
entity) directly to AfriMet.
Long-term off-take agreements with conversion facilities, as well as sales on
the spot market, will be fully investigated for lithium in the next phase of
study. AfriTin has commenced with initial discussion with potential lithium
chemical conversion companies, as well as various traders. The Company expects
to produce bulk samples for potential offtake partners from its petalite bulk
test facility from Q4 2022. Further updates will be provided in due course.
Under steady state conditions the Uis Phase 2 project is projected to produce:
· 15,000 tonnes of tin concentrate per annum (9,000 tonnes of
contained tin per annum)
· 1,000 tonnes of tantalum concentrate per annum (200 tonnes of
contained Ta(2)O(5) per annum)
· 450,000 tonnes of 4% lithium petalite concentrate per annum
(18,000 tonnes of contained Li(2)O, or 45,000 tonnes of contained LCE per
annum)
Considering the stage of the feasibility study, these production rates cannot
be guaranteed.
