* subject to the assumptions, qualifications and limitations set
out below
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.

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:

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

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.

-------------------------
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.

Note: The constraining pit shell is based on a revenue factor of
1.5, employing a 3-year trailing average tin price of USD 20,000/t.
Ore losses and mining dilution were set at 5%. Pit slope angles
were assumed to be 50deg with an assumed metallurgical recovery of
Sn of 80%, producing a concentrate of 60% Sn. Mining, Treatment, G
and A and Selling Costs have been supplied by AfriTin and reviewed
for reasonableness by CSA Global. A Sn cut-off grade of 0.05% Sn
has been applied to resources within the constrained pit. Tabulated
data have been rounded off and this may result in minor
computational errors.
* AfriTin has an attributable ownership of 85% in Uis with the
remaining 15% owned by The Small Miners of Uis (SMU)
