Key consultants appointed to assist in delivering DFS in Q4 2021

HIGHLIGHTS

  • Definitive Feasibility Study (DFS) follows on from highly encouraging studies completed in Q4 2020 (see ASX releases dated 9[th] and 22[nd] October 2020) which support a stand-alone 2Mtpa mining operation with a 40-year mine life.

  • Key consultants including Lycopodium Minerals Pty Ltd, Snowden Mining Industry Consultants Pty Ltd, Knight Piésold Pty Ltd, MBS Environmental and ALS Metallurgy Pty Ltd appointed to ensure a high-quality DFS.

  • Water exploration drilling has identified a number of prospective follow-up targets for full bore development and testing.

  • Comminution Study completed which has identified the potential for further process circuit optimisation.

  • Geotechnical/in-fill drilling confirms the potential to upgrade Inferred parts of the Mineral Resource Estimate (MRE), with several high-grade intersections received, including:

KVGT0013

9.9m @ 1.9% Li2O from 135.9m , including: o 5.1m @ 2.9% Li2O from 135.9m, and 30.8m @ 1.6% Li2O from 260.6m , including: o 3m @ 3.0% Li2O from 261m, and o 4.9m @ 2.5% Li2O from 278.1m

Liontown Resources Limited (ASX: LTR, “Liontown” or “Company”) is pleased to advise that it has moved to the next key pre-development stage at its 100%-owned Kathleen Valley Lithium-Tantalum Project in Western Australia with work now well underway on a Definitive Feasibility Study (DFS).

The DFS, which is scheduled for completion in Q4 2021, follows on from the highly encouraging studies completed in Q4 2020 that included:

  • A Pre-Feasibility Study (PFS) into establishing a 2Mtpa mining operation to produce an average 350,000tpa of spodumene concentrate (SC6) for 40 years; and

  • A subsequent Scoping Study into the potential to undertake downstream processing on-site to produce Lithium Hydroxide or Lithium Sulphate.

Liontown has appointed several highly credentialled consulting groups to assist with the DFS including Lycopodium Minerals Pty Ltd (Process Engineering), Snowden Mining Industry Consultants Pty Ltd (Mine Engineering), Knight Piésold Pty Ltd (Tailings and Hydrogeological Engineering), MBS Environmental (Environmental and Permitting) and ALS Metallurgy Pty Ltd (Metallurgical Test Work).

The Company has also undertaken additional geotechnical and water exploration drilling to acquire data identified by the 2020 PFS which is required to complete the DFS.

The geotechnical drilling comprised six diamond core holes totalling 1,312m ( Appendix 1 ) and was designed to provide rock quality data for the proposed underground portals and the north-western part of the deposit. Data from the holes indicate good ground conditions suitable for underground mining and are consistent with previous drilling.

Two of the geotechnical holes, KVDD0076 and KVDD0077, drilled into an Inferred part of the Mineral Resource ( see Figure 1 ), intersected significant widths of high-grade lithium mineralisation (see Highlights), confirming the continuity of the system. The assay data from KVDD0076 and KVDD0077 will be used to upgrade parts of the Mineral Resource Estimate to the Indicated category, which will subsequently be available for conversion to Ore Reserves as part of the DFS.

The water drilling comprised 10 Reverse Circulation (RC) holes totalling 1,018m with the holes targeting structures defined by aeromagnetic and ground EM data. A number of holes intersected water and further drilling to fully develop 2-3 bores and measure flow rates and draw-down is scheduled for late Q1 2021.

Further metallurgical test work on approximately 3 tonnes of material will also commence during the current Quarter to provide DFS-level data for recovery, variability, grind size optimisation and comminution.

A Process Comminution Study has also been completed which has confirmed the viability of further process optimisation leading to possible capital savings and improved operability through the removal of one stage of crushing and increased grinding mill size. This change will be incorporated into the DFS.

Further market updates will be provided as the DFS progresses.

Kathleen Valley Overview

The 100%-owned Kathleen Valley Lithium-Tantalum Project is located in the North Eastern Goldfields of Western Australia, approximately 400km north of Kalgoorlie ( Figure 2 ) close to well-established transport and energy infrastructure. Liontown acquired the Project in 2017 and has since drilled 461 RC and diamond core holes for a total of 89,066m.

Data from the drilling has been used to prepare a MRE of 156Mt @ 1.4% Li2O and 130ppm Ta2O5 , making Kathleen Valley one of the larger, spodumene-related hard rock lithium resources in the world.

The MRE formed the basis of a PFS completed in October 2020 with the key metrics from the study tabled below:

Description PFS
NPV8%(real) LOM (Post Tax) A$1.12B
IRR (%) LOM (Post Tax) 37%
Payback (years) 3
OPEX US$/t Li2O (dmt) Years 1-10 (exc. royalties)(2)(3) US$283/dmt
LOM Free Cashflow (post tax) A$4.8B
Annual Production 6% Li2O (dmt) 350ktpa
Annual Production 30% Ta2O5 (dmt) 430 tpa
Capital Cost A$M (inc. $67M pre-production costs) A$325M
Ore Reserve 71Mt@ 1.40% Li2O & 130ppm Ta2O5
Production Inventory(1) 79Mt@ 1.40% Li2O & 130ppm Ta2O5
Mine Life (at 2 Mtpa) ~40 years

Cautionary statement: 1The production targets and forecast financial information referred to in the PFS comprise Proven Ore Reserves (19.7%), Probable Ore Reserves (69.8%) and Inferred Mineral Resources (10.5%). The Inferred material included in the inventory is 8.28Mt @ 1.36% Li2O & 120 ppm Ta2O5. The Inferred material has been scheduled such that less than 1Mt is mined in the first ten years, with 6.44Mt at the end of the underground mine life and 0.84Mt after year 25 for the open pit. The Inferred material does not have a material effect on the technical and economic viability of the project. There is a low level of geological confidence associated with inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of indicated Mineral Resources or that the production target itself will be realised.

2 Cash operating costs include all mining, processing, transport, freight to port, port costs and site administration/ overhead costs. Excludes sustaining capital.

3 As royalties are predominantly sales-price dependent they have not been included in cash costs. At PFS average Li2O pricing to 2040 of US$739/t royalties equates to $62/t of 6% Li2O for the 1[st] 10-year case presented above.

Given the highly encouraging results from the PFS, Liontown has commenced a DFS which is scheduled for completion in Q4 2021.

The Company has also undertaken a Scoping Study which supports the establishment of a downstream processing facility on-site to produce lithium hydroxide or lithium sulphate using 6% Li2O spodumene concentrate (SC6) from Kathleen Valley. Further test work is planned to provide the additional data required to determine whether Liontown should pursue this option further.

Appendix 2 – Kathleen Valley – JORC Code 2012 Table 1 Criteria

The table below summarises the assessment and reporting criteria used for the Kathleen’s Corner, Mt Mann deposits and Kathleen Valley Lithium Project Mineral Resource estimate and reflects the guidelines in Table 1 of The Australasian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code, 2012).

Section 1 Sampling Techniques and Data

Criteria JORC Code explanation Commentary
Sampling
techniques
Nature and quality of sampling (eg cut
channels, random chips, or specific
specialised industry standard
measurement tools appropriate to the
minerals under investigation, such as
down hole gamma sondes, or handheld
XRF instruments, etc). These examples
should not be taken as limiting the broad
meaning of sampling.

Sub-surface samples have been collected by reverse
circulation (RC) and diamond core drilling techniques (see
below).

Drillholes are oriented perpendicular to the interpreted
strike of the mineralised trend except where limited access
necessitates otherwise.
Include reference to measures taken to
ensure sample representivity and the
appropriate calibration of any
measurement tools or systems used.
Aspects of the determination of
mineralisation that are Material to the
Public Report.
In cases where ‘industry standard’ work
has been done this would be relatively
simple (eg ‘reverse circulation drilling was
used to obtain 1 m samples from which 3
kg was pulverised to produce a 30 g
charge for fire assay’). In other cases
more explanation may be required, such
as where there is coarse gold that has
inherent sampling problems. Unusual
commodities or mineralisation types (eg
submarine nodules) may warrant
disclosure of detailed information.

RC samples are collected by the metre from the drill rig
cyclone as two 1 m cone split samples in calico bags and a
bulk sample in plastic mining bags.

The 1 m samples from the cyclone are retained for check
analysis. Only samples of pegmatite and adjacent wall rock
(~4 m) are collected for assay.

Diamond core has been sampled in intervals of ~1 m (up to
2.0 m within the main project area) where possible,
otherwise intervals less than 1 m have been selected based
on geological boundaries. Geological boundaries have not
been crossed by sample intervals.
Drilling
techniques
Drill type (eg core, reverse circulation,
open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc) and details (eg
core diameter, triple or standard tube,
depth of diamond tails, face-sampling bit
or other type, whether core is oriented
and if so, by what method, etc).

Drilling techniques used at Kathleen Valley comprise:
o Reverse Circulation (RC/5.5”) with a face sampling
hammer
o NQ2, HQ and PQ Diamond Core, standard tube to a
depth of ~650 m.
o Diamond core holes drilled directly from surface or from
bottom of RC pre-collars. Core orientation was provided
byan ACT REFLEX(ACT II RD)tool.
Drill sample
recovery
Method of recording and assessing core
and chip sample recoveries and results
assessed.

Sample recoveries are estimated for RC by correlating
sample heights in the plastic bag to estimate a recovery for
each metre.

For diamond core the recovery is measured and recorded for
everymetre.
Measures taken to maximise sample
recovery and ensure representative
nature of the samples.

RC drill collars are sealed to prevent sample loss and holes
are normally drilled dry to prevent poor recoveries and
contamination caused by water ingress. Wet intervals are
noted in case of unusual results.

For diamond core loss, core blocks have been inserted in
sections where core loss has occurred. This has then been
written on the block and recorded during the logging process
and with detailedphotographyof dryand wet core.
Whether a relationship exists between
sample recovery and grade and whether
sample bias may have occurred due to

It has been demonstrated that no relationship exists
between sample recovery and grade. No grade bias was
observed with sample size variation.

preferential loss/gain of fine/coarse
material.
Logging Whether core and chip samples have
been geologically and geotechnically
logged to a level of detail to support
appropriate Mineral Resource estimation,
mining studies and metallurgical studies.

All RC drillholes are logged on 1 m intervals and the following
observations recorded:
o
Recovery, quality (i.e. degree of contamination), wet/dry,
hardness, colour, grainsize, texture, mineralogy, lithology,
structure type and intensity, pegmatite and vein type and
%, lithium mineralogy and %, alteration assemblage, UV
fluorescence.

Diamond core is logged in its entirety as per detailed
geological description listed above. Geotechnical logging has
been completed for the entire hole.
Whether logging is qualitative or
quantitative in nature. Core (or costean,
channel, etc) photography.

Logging is quantitative, based on visual field estimates.

Diamond core is photographed post metre marking, for the
entire length of the hole,two trays at a time,wet and dry.
The total length and percentage of the
relevant intersections logged.

Drillholes are logged in their entirety.
Sub-sampling
techniques
and sample
preparation
If core, whether cut or sawn and whether
quarter, half or all core taken.

The core has been cut in half and then quartered for sample
purposes. Half core used for metallurgical studies with the
remaining quarter stored as a library sample.

Density measurements have been taken on all quarter core
samples usingthe Archimedes method.
If non-core, whether riffled, tube sampled,
rotary split, etc and whether sampled wet
_or dry. _

RC samples are collected as rotary split samples. Samples
are typically dry.
For all sample types, the nature, quality
and appropriateness of the sample
preparation technique.

Sample preparation follows industry best practice standards
and is conducted by internationally recognised laboratories;
i.e.
o Oven drying, jaw crushing and pulverising so that 80%
passes -75 microns.
Quality control procedures adopted for all
sub-sampling stages to maximise
representivity of samples.

Duplicates and blanks submitted approximately every 1 in 20
samples.

Standards are submitted every 20 samples or at least once
per hole.

Cross laboratory checks and blind checks have been used at
a rate of 5%.
Measures taken to ensure that the
sampling is representative of the in situ
material collected, including for instance
results for field duplicate/second-half
sampling.

Measures taken include:
o
regular cleaning of cyclones and sampling equipment to
prevent contamination
o
industry standard insertion of standards, blanks and
duplicate samples.

Analysis of duplicates (field, laboratory and umpire) was
completed and no issues identified with sampling
representatively.

Analysis of results from blanks and standards indicates no
issues with contamination (or sample mix-ups) and a high
level of accuracy.
Whether sample sizes are appropriate to
the grain size of the material being
sampled.

Sample size is considered appropriate and is in-line with
industry standards.
Quality of
assay data
and
laboratory
tests
The nature, quality and appropriateness
of the assaying and laboratory procedures
used and whether the technique is
considered partial or total.

Initial assaying (2017) completed by ALS Perth. Subsequent
assaying (2018 onwards) completed by Nagrom laboratories
Perth.

Both laboratories use industry standard procedures for rare
metals such as Li and Ta. Analytical techniques are total.
For geophysical tools, spectrometers,
handheld XRF instruments, etc, the
parameters used in determining the
analysis including instrument make and
model, reading times, calibrations factors
applied and their derivation, etc.

None used.

Accuracy and quality of surveys used to
locate drillholes (collar and down-hole
surveys), trenches, mine workings and
other locations used in Mineral Resource
estimation.

All drill collars and geochemical samples are initially located
using a handheld GPS.

Drill collars are subsequently surveyed accurately by a
licensed surveyor using DGPS techniques. Eastings and
northings are measured to within +/-2 cm while elevations
are measured to within +/-10 cm.

All RC drillholes have been surveyed by a multi-shot digital
downhole camera provided by the drilling contractor.

All diamond drillholes have been surveyed with a REFLEX EZI-
SHOT(1001)magnetic single shot camera.
Specification of the grid system used.
GDA 94 Zone 51.
Quality and adequacy of topographic
control.

Initial collar elevations are based on regional topographic
dataset.

Drillhole collars are surveyed post drilling with DGPS (see
above).

Further topographic data (20 cm contours) has been
provided for the Project bya LIDAR flown byFugro.
Data spacing
and
distribution
Data spacing for reporting of Exploration
Results.

Drillhole spacing varies due to initial drill programs largely
designed to test the down-dip potential of mineralised
outcrops. The drill section spacing is 40 m to 100 m and on-
section spacingisgenerally30 m to 60 m.

Sample
security
The measures taken to ensure sample
security.

Sample security is not considered to be a significant risk
given the location of the deposit and bulk-nature of
mineralisation.

Nevertheless, the use of recognised transport providers,
sample dispatch procedures directly from the field to the
laboratory, and the large number of samples are considered
sufficient to ensure appropriate sample security.

Acknowledgment and appraisal of
exploration by other parties.

Multiple phases of exploration have previously been
completed for gold and nickel. This has not been reviewed in
detail due to Liontown’s focus on rare metal pegmatites.

There has been limited sporadic prospecting for Li, Ta and Sn,
principally by Jubilee Mines (subsequently taken over by
Xstrata). Work comprised geological mapping, broad spaced
soil sample lines and rock chip sampling of the pegmatites.
Details of the methods and procedures used have not been
documented.

There has been no previous drill testing of the Li and Ta
prospective pegmatites prior to Liontown acquiring the
Project.
Geology Deposit type, geological setting and style

The Project is located on the western edge of the Norseman-
Wiluna Belt within the Archaean Yilgarn Craton.

The Kathleen Valley Project contains a series of quartz-
feldspar-muscovite-spodumene pegmatites hosted in mafic
rocks related to the Kathleen Valley Gabbro or the Mt Goode

Geological
interpretation
Nature of the data used and of any
assumptions made.

Both assay and geological data were used for the
mineralisation interpretation.

The lithium mineralisation is defined by a nominal 0.4% Li2O
cut-off grade.

Continuitybetween drillholes and sections isgood.
The effect, if any, of alternative
interpretations on Mineral Resource
estimation.

No alternative interpretations were considered.

Any alternative interpretations are unlikely to significantly
affect the Mineral Resource estimate.
The use of geology in guiding and
controlling Mineral Resource estimation.

Geological logging (including spodumene crystal orientation
from the diamond core) has been used for interpretation of
thepegmatites.
The factors affecting continuity both of
grade and geology.

The mineralisation is contained within pegmatite veins that
are readily distinguished from the surrounding rocks.

Sectional interpretation and wireframing indicates good
continuity of the interpreted pegmatite veins both on-
section and between sections.

The confidence in the grade and geological continuity is
reflected bythe assigned resource classification.
Dimensions The extent and variability of the Mineral
Resource expressed as length (along strike
or otherwise), plan width, and depth
below surface to the upper and lower
limits of the Mineral Resource.

Twenty lithium mineralised pegmatites have been identified
at the Kathleen Valley Project which extend from surface to a
depth of 640 m.

At Mt Mann, two steeply-dipping (-70° west) pegmatites
have been drilled over a strike length of 1,200 m and to a
vertical depth of around 300m to 400 m. The two
pegmatites are up to 35 m thick and have average
thicknesses of 9 m and 11 m.

At Kathleen’s Corner, 18 sub-horizontal pegmatites have
been drilled over an area of 1,800 m by 1,300 m. These
pegmatites outcrop in the northeast and are up to 40 m thick
with an average thickness of 8 m. The pegmatites coalesce
and merge with the Mt Mann pegmatites at approximately
300 m to 400 m below surface to form a single, thick (35 m
to 75 m) mineralised body that extends for a further 600 m
to 700 m down-dip.
Estimation
and modelling
techniques
The nature and appropriateness of the
estimation technique(s) applied and key
assumptions, including treatment of
extreme grade values, domaining,
interpolation parameters and maximum
distance of extrapolation from data
points. If a computer assisted estimation
method was chosen include a description
of computer software and parameters
used.

Data analysis and estimation was undertaken using Snowden
Supervisor and Datamine software.

Lithium oxide (Li2O) % and tantalum pentoxide (Ta2O5) ppm
block grades were estimated using ordinary kriging (OK).
Optiro considers OK to be an appropriate estimation
technique for this type of mineralisation.

Caesium (Cs), potassium (K), niobium (Nb), rubidium (Rb),
phosphorus (P) and tin (Sn) block grades were estimated
using ordinary kriging (OK). These additional variables were
included for analysis of the mineralisation and fractionation
trends of the pegmatite, from the K/Cs, K/Rb and Nb/Ta
ratios.

The nominal spacing of the drillholes is 50 m by 50 m. The
along section spacing ranges from 30 m to 100 m and on-
section spacing ranges from generally 30 m to 60 m.

Almost 90% of the assay data within the lithium mineralised
pegmatites is from samples of 1 m intervals, 1.5% is from
sample of >1 m (to a maximum of 2 m) and almost 9% is
from intervals of less than 1 m. The data was composited to
1 m downhole intervals for analysis and grade estimation.

Variogram analysis was undertaken to determine the kriging
estimation parameters used for OK estimation of Li2O and
Ta2O5.

Li2O mineralisation continuity was interpreted from
variogram analyses to have an alongstrike range of 145 m to

LIONTOWN RESOURCES LIMITED | PAGE 14

ASX ANNOUNCEMENT

Criteria JORC Code explanation Commentary
230 m and a down-dip (or across strike) range of 110 m to
230 m.

Ta2O5mineralisation continuity was interpreted from
variogram analyses to have an along strike range of 58 m to
150 m and a down-dip (or across strike) range of 47 m to 170
m.

A maximum extrapolation distance of 50 m was applied
along strike and down dip extrapolation was generally 30 m.

Kriging neighbourhood analysis was performed in order to
determine the block size, sample numbers and discretisation
levels.

Three estimation passes were used for Li2O and Ta2O5; the
first search was based upon the variogram ranges; the
second search was two times the initial search and the third
search was up to four times the second search and the
second and third searches had reduced sample numbers
required for estimation.

Within the lithium mineralised pegmatites almost 84% of the
total Li2O block grades were estimated in the first search
pass, 14% within the second search pass and 2% estimated in
the third search pass.

Within the pegmatites 75% of the Ta2O5block grades were
estimated in the first pass, 24% in the second pass and 1% in
the third pass.

The estimated block model grades were visually validated
against the input drillhole data and comparisons were
carried out against the declustered drillhole data and by
northing,eastingand elevation slice.
Description of how the geological
interpretation was used to control the
resource estimates.

Geological interpretations were completed on sections
which were wireframed to create a 3D interpretation of the
mineralised pegmatites.

The interpretation of mineralisation was based on geological
logging and Li2O content. A nominal grade of 0.4% Li2O was
used to define the mineralisation within the interpreted
pegmatites.

The mineralised domain is considered geologically robust in
the context of the resource classification applied to the
estimate.
Discussion of basis for using or not using
grade cutting or capping.

Li2O and Ta2O5have low coefficients of variation (CV). Some
higher-grade outliers were noted and the Ta2O5grades were
capped (top-cut).

Cs, K, Rb, P and Sn have low coefficients of variation and Nb
has a moderate coefficient of variation (1.4). A small
number of high-grade outliers are present in the Cs, Nb, Rb,
P and Sn data and grades were capped.

The top-cut level was determined using a combination of
top-cut analysis tools, including grade histograms, log
probability plots and the CV.
The availability of check estimates,
previous estimates and/or mine
production records and whether the
Mineral Resource estimate takes
appropriate account of such data.

The Mineral Resource was first estimated for the Kathleen’s
Valley Lithium Project in August 2018. The Mineral
Resource, comprising 21 Mt at an average grade of 1.4% Li2O
and 170 ppm Ta2O5, was reported above a cut-off grade of
0.5% Li2O

Additional drilling was undertaken during 2019 and the
resource was in July 2019. The July 2019 Mineral Resource,
comprising 74.9 Mt at an average grade of 1.3% Li2O and 140
ppm Ta2O5,was reported above a Li2O cut-off grade of 0.5%
for open pit potential (above 200 mRL) and 0.7% for
undergroundpotential(below 200 mRL).

Additional drilling was undertaken in 2019 and 2020 and the
resource was in February 2020. The February 2020 Mineral
Resource, comprising 139 Mt at an average grade of 1.33%
Li2O and 140 ppm Ta2O5, was reported above a cut-off grade
of 0.55% Li2O.

Since the February 2020 Mineral Resource was estimated
data from an additional 16 RC holes (for a total of 6,616 m)
and 28 DD holes (for a total of 9,682 m) have been
incorporated into the resource database.

The resource tonnage has increased from 139 Mt in February
2020 to 156 Mt in May 2020, while the average grade has
increased from 1.33% Li2O to 1.35% Li2O. The Ta2O5grade
has decreased from 140 ppm to 130 ppm.

Noproduction has occurred.
The assumptions made regarding
recovery of by-products.

An Investigation of tantalum recovery by magnetic separation
and gravity upgrade to produce a tantalum by-product was
undertaken in 2020. Using stage recoveries, the overall Ta2O5
reporting to concentrate has been estimated as 56% to a
grade of 15.3% based on test work. A mineralogical review
indicates potential to produce a 30% Ta2O5concentrate at an
offsite upgrade facility.

Further work on tantalum recovery is anticipated as part of
theplanned DFS.
Estimation of deleterious elements or
other non-grade variables of economic
significance (e.g. sulphur for acid mine
drainage characterisation).

Deleterious elements were not included in the Mineral
Resource estimate.

Liontown does not routinely assay drill samples for iron, the
main deleterious element, due to:
o
contamination from drill bits and rods during drilling
operations; and
o
contamination during sample preparation from crushing
and milling equipment.
o
Assaying of blank, silica only material inserted as part of
QAQC protocols indicates that contamination from
sample preparation adds 0.1% to 1% Fe2O3to the
sample.
o
Analysis of data indicates the iron content in the
pegmatites averages <0.5%.

Sulphur assays have been determined for more than 27,000
host rock samples – results indicate that acid mine drainage
will not be a significant environmental factor.
In the case of block model interpolation,
the block size in relation to the average
sample spacing and the search employed.

Grade estimation was into parent blocks of 10 mE by 10 mN
by 3.0 mRL.

Orelogy Consulting Pty Ltd (who are undertaking mining
studies for Liontown) advised that mining is likely to be
undertaken using a block size of 10 mE by 10 mN on 3 m
benches

This block dimension was confirmed by kriging
neighbourhood analysis and reflects the variability of the
deposit as defined by the current drill spacing and
mineralisation continuity determined from variogram
analysis.

Sub-cells to a minimum dimension of 2.5 mE by 2.5 mN by
0.5 mRL were used to represent volume.
Any assumptions behind modelling of
selective mining units.

Selective mining units were not modelled.
Any assumptions about correlation
between variables.

Li2O and Ta2O5are not correlated. Both Li2O and Ta2O5were
estimated independently.

Correlation coefficients for Cs, K, Nb, Rb, P and Sn within the
pegmatites indicate that they are not correlated, except for K
and Rb which have a highpositive correlation(0.87). All

No production has taken place and thus no reconciliation
data is available.
Moisture Whether the tonnages are estimated on a
dry basis or with natural moisture, and
the method of determination of the
moisture content.

Tonnages have been estimated on a dry basis.
Cut-off
parameters
The basis of the adopted cut-off grade(s)
or quality parameters applied.

A cut-off grade of 0.55% Li2O has been selected to represent
the portion of the resource that may be considered for
eventual economic extraction by a combination of open pit
and underground mining methods.

This cut-off grade has been selected by Liontown Resources
in consultation with Optiro based on current experience and
in-line with cut-off grades applied for reporting of Mineral
Resources of lithium hosted in spodumene bearing
pegmatites elsewhere in Australia.
Mining factors
or
assumptions
Assumptions made regarding possible
mining methods, minimum mining
dimensions and internal (or, if applicable,
external) mining dilution. It is always
necessary as part of the process of
determining reasonable prospects for
eventual economic extraction to consider
potential mining methods, but the
assumptions made regarding mining
methods and parameters when
estimating Mineral Resources may not
always be rigorous.

The mineralisation at Kathleen Valley extends from surface
and would be suitable for open pit mining. High grade
mineralisation is present at depth and would be suitable for
underground mining.

The Kathleen Valley Lithium Project is located in a well-
established mining region in close proximity to existing
transport, energy and camp infrastructure.

On the basis of these assumptions, it is considered that there
are no mining factors which are likely to affect the
assumption that the deposit has reasonable prospects for
eventual economic extraction.
Metallurgical
factors or
assumptions
The basis for assumptions or predictions
regarding metallurgical amenability. It is
always necessary as part of the process of
determining reasonable prospects for
eventual economic extraction to consider
potential metallurgical methods, but the
assumptions regarding metallurgical
treatment processes and parameters
made when reporting Mineral Resources
may not always be rigorous.
2019 Pre-feasibility study

A Pre-feasibility level test work program was conducted at
ALS in Perth to provide sufficient test data to develop the
process design criteria for the Project. A total of 81 samples
from across the three main areas (Mt Mann, Kathleen Corner
and Kathleen Valley North) were selected for the Pre-
feasibility study. A master composite was created for testing
from these samples which are representative of the whole
deposit and include a range of grades and depths. No
variability test work has been undertaken at this time.

Key aspects of the metallurgical test work included the
following:
o head assay
o SMC testing on five comminution samples
o size by size assay
o crushing and wet screening at three sizes
o heavy liquid separation (HLS) at three crush and screen
sizes
o Dense media separation (DMS) of a bulk sample
o bond ball work index on DMS middling’s
o magnetic separation to remove ferrous materials
o rougher flotation to examine collector choice, residence
time, desliming and conditioning
o cleaner flotation to examine residence time and number
of stages
o thickening of flotation and slime tailings (in progress)
o filtration of concentrate
o rheology of tailings.

Key results from the test work indicated that:
o Samples were moderately competent with comminution
results similar to other pegmatites.
o Size bysize and wet screeningdata indicated that there

was a trade off in crush size and screen size with
liberation. A finer crush size increased liberation in the
HLS stage but increased fines production. A crush size of
6 mm was selected.
o DMS testing showed a saleable concentrate with a grade
of more than 6% Li2O could be produced together with a
low-grade coarse tail.
o Grind optimisation of the flotation feed indicated a
primary grind of 125 microns gave the best recovery and
was selected for subsequent test work.
o Rougher flotation test work indicated that a modified
oleic acid collector gave the best flotation performance.
o Batch cleaner flotation results indicated a concentrate
with a grade of more than 6% Li2O could be produced
together.
o Concentrate filtration test work, currently being finalised,
has indicated that vacuum filtration will be adequate for
dewatering.
o Rheology test work indicated the tailings had low
viscosity at the proposed tailings density.

The metallurgical process consisted of three-stage
comminution including high-pressure grinding rolls (HPGR),
Dense Medium Separation (DMS) followed by flotation.

The feed composite used in the PFS test work consisted of
diamond drill core and was compiled based on the mine plan
for the study. The feed composite was deliberately
diluted/blended with 10% iron-rich gabbro which hosts the
mineralised pegmatites.

The PFS test work did not include any iron removal ahead of
DMS separation and only low intensity magnetic separation
or iron removal ahead of flotation. A combined concentrate
with a grade of 6.1% Li2O containing 1.42% Fe2O3 was
produced from the PFS composite sample.
2020 Metallurgical Testwork
The 2019 testwork program was focused on developing
preliminary design data for a flowsheet incorporating Dense
Media Separation (DMS) of a coarse feed followed by flotation of
the DMS middling’s and fines. Several areas were further
investigated post the PFS program in 2020 and included:

The impact of change in lithium head grade on overall
recovery.

Further investigation of Whole Ore Float (WOF)

Investigation of tantalum recovery by magnetic separation
and gravity upgrade to produce a tantalum by-product.
The 2020 program investigated these areas as part of the 2020
pre-feasibility study.
The source of the grade variation samples were the intercepts
remaining from the original drill program in 2019. The drill hole
intercepts were sorted by lithium grade (based on geological
assays) and grouped into the following grade targets: 1.0%, 1.1%
1.2%, 1.3%, 1.4%, 1.7% 2.0%.
WOF was tested on all the grade samples. The same flotation
regime was used as tested in the PFS at a grind size P80 of 125
µm.
The DMS-Flotation route was tested for all the grade samples
under the same conditions as for the 2019 PFS.

Outcomes:-

Higher grade material for both processing options has a
higher recovery which supports the strategy of targeting high
grade zones using underground mining and optimised open-
pit shells;

WOF has the potential to produce a higher grade SC6.0 and
improved performance with a greater degree of control;
Following the outcomes of the testwork a decision was made to
base the 2020 PFS on a WOF flowsheet per ASX release dated
9th June 2020
An Investigation of tantalum recovery by magnetic separation
and gravity upgrade to produce a tantalum by-product was
undertaken. A sample of PFS composite was used for the
testwork as it provided a control against other treatment routes
already tested.
The sample was ground to a P80 passing size of 125 µm like all
the flotation feed samples. The ground sample was then treated
through a laboratory WHIMS separator followed by gravity
separation. Following the gravity concentration of the primary
magnetic separation magnetics, the remaining tails was
subjected to sequential magnetic separation.
Outcomes:-

Using stage recoveries, the overall Ta2O5reporting to
concentrate has been estimated as 56% to a grade of 15.3%
based on test work. A mineralogical review indicates
potential to produce a 25-30% Ta2O5 concentrate at an
offsite upgrade facility; and

Magnetic and gravity separation used to recover tantalum
also reduces iron levels in the potential flotation feed by up
to 55%.
As both the WOF and Ta2O5flowsheets have considerable scope
for further optimisation, this will form part of the DFS upgrade
test work program to be completed in 2021.

In general, the pegmatites that have been tested by the 50 m
by 50 m spaced drillholes have high confidence in the
geological interpretation and, having higher estimation
quality, were classified as Measured.

Areas where the drill spacing is up to 60 m by 100 m that
have good confidence in the geological interpretation and
where the majority of block grades were estimated within
the first search (but where the estimation quality is lower
than the Measured areas) were classified as Indicated.

Areas where the drill spacing is up to 60 m by 100 m, that
have good confidence in the geological interpretation and
where the majority of block grades were estimated in the
second and third search passes or in areas of grade
extrapolation have been classified as Inferred.
Whether appropriate account has been
taken of all relevant factors (ie relative
confidence in tonnage/grade estimations,
reliability of input data, confidence in

basis for the conversion to
an Ore Reserve.

Clear statement as to
whether the Mineral
Resources are reported
additional to, or inclusive of,
the Ore Reserves.
The mineral Resource Estimate used as a basis for the
conversion to the Ore Reserve was provided on the 11th May
2020 with Christine Standing, employee of Optiro, as the
Competent Person.
The total Mineral Resource of 156Mt at 1.4% Li2O includes: -
• 20 Mt of Measured at 1.3% Li2O and 140ppm Ta2O5,
• 105 Mt of Indicated at 1.4% Li2O and 130ppm Ta2O5and;
• 32 Mt of Inferred at 1.3% Li2O and 110ppm Ta2O5.
The Mineral Resources are reported inclusive of the Ore
Reserve.

Site visits
Comment on any site visits
undertaken by the
Competent Person and the
outcome of those visits.

If no site visits have been
undertaken indicate why
this is the case.
The Open Pit Competent Person, Mr Jake Fitzsimons, visited
the proposed Project site on 28th September 2019. The
following observations were made:

The site is accessed directly from the Goldfields Highway.

The site is dominated by Mt Mann which rises
approximately 50 m above the surrounding terrain, and
Jones Creek dry watercourse which passes through the
northern half of the mining area flowing from east to
west.

Existing access between the North and South deposits is
across Jones Creek via a 10 m wide concrete ford with
opportunity to widen to 12-15 m without disturbing any
trees.

Pegmatite outcrop exists across the site.

Drilling core examined on site was hard and very
competent in both the gabbro hanging wall rock and
pegmatite ore zones.
The underground Competent Person, Mr Ben Wilson has not
visited the site, based on the visit by Mr Jake Fitzsimons detailed
above who is a coworker at Orelogy. The data collected on the
site visit by Mr O’Bryan & Mr Fitzsimons has been shared with
Mr Wilson.
Peter O’Bryan of Peter O’Bryan and Associates, visited the site

Orelogy undertook the mining component of this PFS, and in
the course of the study, produced optimisations, designs,
schedules and a cost model.
Modifying factors considered in the open pit mine planning
process included mining dilution and ore loss, slope design
criteria and practical mining considerations.
The activities and findings of all other disciplines are
summarized in the 2020 PFS document, including details of
other modifying factors such as processing recoveries, costs,
revenue factors, environmental and heritage considerations,
etc.
Overall, the result of the open pit and underground mine
plans demonstrate that the Kathleen Valley Lithium Project is
technically achievable and economically viable at the
forecast spodumene price.
Modifying factors considered in the underground mine planning
process included mining method selection, minimum mining
width, mining dilution and ore loss, geotechnical stope stability
criteria, pillar and filling requirements, and practical mining
considerations, for example, materials handling, ventilation and
dewatering.
Cut-off
parameters

The basis of the cut-off
grade(s) or quality
parameters applied.
The Ore Reserves are reported at a 0.7 - 0.75% Li2O cut-off
grade depending on the timing with 0.75% used in the early
open pit mining phase and 0.7% used for the final open pit
phase. This cut-off is above the theoretical economic cut-off
of 0.35% Li2O and has been adopted as the grade tonnage
curve shows very little material below this grade.
The Ore Reserves are reported as material contained within
stope designs done at cut off grades of 1.2 & 1.5% Li2O cut-off
grade based on flat or vertical zones within the deposit.
This cut-off has been adopted in the context of the prevailing
market conditions and surrounding open pit Ore Reserve. The
cut-off is above the theoretical underground economic cut-off of
0.95% Li2O as the grade tonnage curve shows very little material
below this grade.
A development cut-off grade of 0.8% Li2O has been used. This
cut-offgrade represents thegrade at which additional haulage

Resource to an Ore Reserve
(i.e. either by application of
appropriate factors by

The mining dilution factors

Any minimum mining widths
used.

The manner in which
Inferred Mineral Resources
are utilised in mining studies
and the sensitivity of the
outcome to their inclusion.
The open pit and underground Ore Reserves are
underpinned by a mine plans that deliver pegmatites for
processing on site to produce SC6.0 for export via the
Geraldton port.
The mine planning activities included open pit and
underground optimisation, final and interim stage designs,
mine scheduling and cost estimation.
The mine plans indicated that the combined Ore Reserve
derived from the Mineral Resource Estimate can easily meet
the processing feed requirements for the 2.0 Mtpa
production target with a mine life of approximately 40 years.
A conventional open pit mining method using excavators
and rigid dump trucks was selected as the preferred
mining method. Experienced mining contractors will
undertake all aspects of the mining operation.
Supervision, grade control and planning will be
undertaken by an Owner’s team. All material will be
blasted. Bulk waste will be blasted on 12 m benches and
the ore zones will be blasted on 6 m benches and mined in
two or three flitches for greater selectivity (depending on
the point in the mine schedule) with ore delivered to
blend fingers on the ROM pad.
Open pit geotechnical guidance was provided by Peter
O’Bryan and Assoc. with an allowance for ramps on the
footwall and geotechnical berms on the hanging walls.
Oxidation is shallow from 5-20 m in depth with slope angles
of ~50oon the hanging wall and ~37oon the footwall. Overall
slope angles in fresh material were ~57oon the hanging wall
and ~45oon the footwall. As the Kathleen Valley orebody
dips at substantially less than wall angle constraints, the pit
shells are optimally shallower than these angles to the south-
west.
As for Open Pit.
Detailed mine designs were undertaken in the Deswik.CAD
mining software package, incorporating all available
geotechnical and practical considerations.
The Kathleen Valley gabbros and spodumene-bearing
pegmatites are massive, and rock mass quality is consistently
very good, allowing the consideration of mass mining methods
in the steeper and wider orebodies. Underground operations
are expected to be carried out in essentially dry ground. The
deepest mining planned is at ~440m below surface.
The underground mining area consists of two main mining
areas, the Mt Mann steeply dipping ore domains, located
underneath and to the south-west of the open pit, and the
North-West Lodes, flat dipping overlaid lodes (“the Flats”),
located to the north-west of the open pit.
Due to the significant variation in dip and orebody width
across the mining areas, three different mining methods have
been selected. The steeply dipping Mt Mann orebodies will be
mined by transverse retreat open stoping, with Cemented
Paste Backfill (CPB). In the North-West Lodes area, where the
orebody width is greater than 10m, longitudinal retreat open
stoping with CPB will be employed. In narrower areas of the
North-West Lodes, Room and Pillar Mining, without filling, will
be employed.
Within these mining methods, several different variations will
be employed, in order to meet geotechnical stability
guidelines while maximising productivity. These variations are
summarised in the table below:

The infrastructure
requirements of the selected
mining methods.
An allowance for Grade Control drilling was made based on a
dedicated RC drilling program at 24 m vertical intervals.
The May 2020 Datamine Mineral Resource model
(kv_or_apr2020.dm) was used as a basis for the conversion
to an Ore Reserve.
To establish mineable quantities, a number of open pit
optimisations were completed on the Resource model
after applying ore loss and dilution to the edges of the
mineralisation. The base case optimisations considered
Measured and Indicated materials only, excluded the
Jones Creek watercourse and applied pricing, recoveries
and other modifying factors. All other optimizations
include Measured, Indicated and Inferred after it was
shown that the Inferred material had no impact on shell
size.
The shell selection was based on the business objectives
of maximising the discounted cash flow whilst providing
sufficient mine life.
Options investigated evolved as both Underground and
open pit options were simultaneously progressed, with the
approach by_Orelogy_as follows:-

Development of an optimised open pit schedule at a
0.75% Li2O Cut-off grade for Stages 1 and 2 for the
early mining phase and 0.7% Li2O Cut-off grade for the
final three stages. The open pit schedule was
manipulated by delaying stages or stretching over
longer time periods.

Assessment of flat and vertical Underground ore
bodies separately at cut off grades of 0.95%, 1.2% and
1.5% Li2O respectively and sequenced Underground
ore in conjunction with the open pit schedule to
maximise project returns
Schedules from Underground and open pit were combined
toproduce an optimised overallproject mineplan
These mining methods are considered appropriate, as they
provide a good balance of economic recovery of the resource,
cost minimisation, and safety.
The Mt Mann mining sequence is bottom up within each
stoping panel, generally four stopes high. The overall
sequence is top down. Stopes will be mined in a primary-
secondary sequence. The lower 15m of the bottom stope of
each panel will be filled with a higher strength CPB (8% rather
than the standard 4%), to maintain geotechnical stability when
the lower panel is mined underneath. Stopes will be mined
from footwall to hangingwall, to avoid undercutting previously
filled CPB stopes. Where practicable, in the secondary stopes,
rock filling has been utilized to minimize waste haulage to
surface.
In the North-West Lodes, the mining sequence for the open
stopes is similarly bottom up, with CPB used to maintain
geotechnical stability. The Room and Pillar stopes will also be
mined bottom up, but will not be filled.
The use of fill in the open stopes avoids the need for pillars
between stopes to maintain stope stability. Given the width
of the orebody, appropriately sized pillars would significantly
reduce the extraction percentage, and hence the economic
viability of the orebodies. Stopes are sequenced to manage
the open voids underground and maintain geotechnical
stability.
Access to the mine, for personnel, equipment and ore
haulage, will be via a main surface portal to the south-west of
the pit, and an in-pit portal, as the pit progresses.

For the open pit, the model was diluted in a two-step
process:

Regularisation to a SMU size of 5 m x 5 m x 2 m for the
material within the 0.6 revenue factor shell for phase 1
mining

Regularisation to a SMU size of 5m x 5m x 3m for the
material outside the 0.6 revenue factor shell for phase 2
mining.

Secondary edge dilution was applied to the edges of the
ore zones to account for the steeply dipping Mt Mann
mineralisation.
The resulting mining model reported:

2.6% dilution and 6% ore loss for the 2 m flitch height in
Stage 1 and Stage 2 at 0.75% Li2O cut-off grade.

3.2% dilution and 6% ore loss for the 3 m flitch height in
the other 3 stages at 0.7% cut-off grade.
No additional mining recovery factors were applied.
The final pit and stages were designed with 40 m minimum
mining width between cutbacks and 25 m at the base of the
pit.
Only Measured and Indicated material were used in
reporting of Ore Reserves. Inferred material was treated as
waste in the Stage 1 and 2 pits. The LOM schedule included a
total of 840kt of Inferred material with the later pit stages.
Open stope designs were based upon a design Hydraulic
Radius of 10.0m, derived using empirical methods by Peter
O’Bryan, of Peter O’Bryan and Associates. Sub-level intervals
and hence stope heights were selected to maintain stable
hydraulic radii, balanced with what would be achievable by
production drilling with an acceptable level of accuracy.
Room and pillar designs were also derived using empirical
methods by Peter O’Bryan, of Peter O’Bryan and Associates.
Two different pillar sizes were recommended based on
orebody width, as detailed in the previous table.
Mining dilution has been modelled with design dilution, CPB
dilution and development dilution.
Design dilution: During the generation of stope shapes, a
dilution skin of 0.5m was added to the footwall and hanging-
wall of all stopes. This was applied geometrically.
CPB dilution: Mining of secondary stopes underneath and
next to CPB will likely result in some dilution of ore. This has
been estimated at 0.3m from the walls of the stope and 0.5m
from the back. This volume of paste was added to the stope
tonnage on a per-stope basis at zero grade (pure dilution).
Development dilution: similarly, where part of an ore
development heading protrudes beyond the orebody contact,
the ore grade of the volume mine is lowered accordingly. No
additional tonnage allowance for overbreak has been made.
Indicative ring designs were undertaken for representative
stopes from each mine area, and the three dilution factors
estimated based on the geometry of the design.
The capacity of the paste plant is limited by the volume of
tailings produced by the processing plant. Mining has been
scheduled to ensure the maximum filling capacity of
584,000m3per year is not exceeded.
Mining recoveries of 95% were applied to all open stopes, and
90% for all room and pillar stopes, to account for ore within
the stope shape that could not be extracted. This occurs
primarily due to geometry issues of boggers navigating around

External infrastructure requirements for the project are
minimised due to the project’s location in the Goldfields
area of Western Australia. The Goldfields highway and
132 kV TransAlta overhead electrical power line are located
within 1 km of the site. A borehole has been proposed for
water supply, and typical site facilities such as camp
accommodation and facilities, sewerage plant, processing
plant,maintenance facilities,and tailings storage will be
90-degree corners and being unable to fully reclaim all blasted
ground.
Due to the requirement to leave behind ore pillars in the
Room and Pillar stopes, mining recovery is further reduced
from operational mining recovery, to 84% for the 5m-7m wide
stopes, and 82% for the 7m-10m wide stopes.
Mining recoveries of 100% were applied to all development,
with the expectation that development headings could be
bogged clean.
The minimum mining width used depended on the mining
area and method. These widths are shown in the Mining
Method table above. However, the absolute minimum mining
width for the project is 5 m, which comprises a 4 m orebody
width and 0.5 m of dilution in both hanging-wall and footwall.
Inferred material was optimised, designed and scheduled.
Stopes have been classified on a dominant resource category
basis, where the dominant resource category for the stope is
reported as the resource category for the entire stope. Proven
and Probable Reserve categories have an average of 3%
Inferred material and 2% waste material that is included in the
stope shapes. This is judged reasonable dilution of the Ore
Reserve. Stopes that have a dominant resource category of
Inferred are not reported as part of the Ore Reserves, and
similarly have an average of 5% Indicated Resources and 5%
waste material contained within the Inferred stope shapes.
The base case schedule for the PFS includes Inferred material
as well and Measured and Indicated material. However, this
Inferred material has been scheduled as much as possible at
the end of the underground mine life, and as such does not
have a material effect on the technical and economic viability
of the project. The majority of the Inferred material has been
included in the base case schedule on the basis that it is
contiguous with the surrounding Indicated mineralisation, and
forms part of the overall extraction sequence for that area of
the deposit.

Environmental
Two distinct phases of testwork were conducted for the
Kathleen Valley Project in both 2019 and 2020. The Initial work
resulted in the development of a DMS-Flotation flowsheet
which was revised in June 2020 to a Whole Ore Flotation
flowsheet.
In 2019 a total of 81 intercepts from across the three main
areas (Mount Mann, Kathleen Corner and North) were
selected for the pre-feasibility study. These samples include a
spatial spread, grade range and depth. A master composite
was created for testing.
A grade- recovery relationship was defined from testwork
utilizing a WOF flowsheet.
During 2020 further work was undertaken in order:

To develop and test a WOF flowsheet;

To establish grade-recovery curves for both DMS and
WOF flowsheets at a range of composite grades to enable
direct comparisons between each; and

Test and develop of preliminary flowsheets to support
the extraction of tantalum.
Following the outcomes of the testwork a decision was made
to base the 2020 PFS on a WOF flowsheet per ASX release
dated 9th June 2020
The process has been tested at pre-feasibility level in the
laboratoryand further work is ongoing.

impacts
Refer to main body of announcement and JORC table
Section3.
Geochemical characterisation of waste rock has been
completed with representative samples (70 fresh rock, 24
oxide and transitional waste and 4 low grade ore samples)
assessed for potential for saline, neutral or acid and
metalliferous drainage (AMD) as well as other general
geochemical properties. Several minor pockets of potentially
acid forming (PAF) material was identified to be present in
the dolerite gabbro and contact zone waste rock materials of
the Mt Mann mine area.
Provided parcels of PAF material originating from the dolerite
gabbro and contact zone mine wastes are managed
appropriately, there is a low risk of fresh waste rock
adversely impacting groundwater and surface water quality
via seepage or run-off from rainfall.
Characterisation of tailings generated by metallurgical test
work has been completed. Samples were assessed for
potential of saline, neutral or acid and metalliferous drainage

Liontown has again utilised the services of Roskill for its price
forecast assumptions for tantalum concentrate (30 Non-Class
7 Specification) as applied in the PFS.
Roskill has provided a forecast price through to 2040 on a
real, US$/lb CIF China basis for “Arm’s Length” pricing.
Like SC6.0, at this stage future tantalum concentrate
production from Kathleen Valley remains 100% uncommitted
in order to maintain maximum flexibility over funding and
development options. For the purposes of the PFS, it has
been assumed that Liontown will sell 100% of its production
on arm’s length terms to unrelated parties on a yearly basis.
Roskill provided an average price of US$70/lb CIF China for
2025 to 2040. Liontown has adjusted Roskill’s CIF China
prices to an FOB Fremantleprice bydeductingUS$0.1per

from Australia as the ultimate destination of tantalum
concentrate produced from the Kathleen Valley Project is not
known at this stage. This results in an average price of
US$69.9/lb FOB Fremantle.
Noting that while the PFS extends beyond Roskill’s 2040
forecasts, Liontown has assumed it reasonable to use the
2040 price of CIF US$65/lb as the basis from 2041 to 2064.

Price and volume forecasts
and the basis for these

For industrial minerals the
customer specification,
Demand for lithium is forecast to increase significantly over
the next decade driven using lithium ion batteries in
automotive applications. Whilst there is a current oversupply
of SC6.0 largely because of new mine capacity in Australia, it
is expected that reduction in mine output from mines in
Australia in 2021-2023 may initiate a phase of rebalancing.
With continued strong demand and consumption growth, a
supply deficit is expected to occur in the mid-2020’s.
Tantalum is used in high performance capacitors, superalloys
and other applications consumed widely in aerospace, military
and consumer electronics.

testing and acceptance
requirements prior to a
supply contract.
Tantalum is a critical material for high performance
applications, but global production is relatively small and
limited to a few key regions and producers.
With ongoing electrification of homes and vehicles, tantalum
should play an increasingly important role from ensuring
safety in autonomous vehicles to maintaining performance in
the next generation of electrical devices and communications
technology. While capacitors will remain the largest
application (accounting for around 36% of the 2.4kt Ta of
estimated demand in 2019), the largest growth will come from
chemical applications and tantalum mill products.
Supply-side disruptions have traditionally had the biggest
impact on concentrate price trends in recent years, including
the introduction of the Dodd-Frank Act in 2010, the fire at
AMG’s Brazilian Mibra operation in 2017, and more recently,
variance in Australian by-product supply.

The Ore Reserve estimate is an outcome of the 2020 Mining
Pre-Feasibility Study with geological, mining, metallurgical,
processing, engineering, marketing and financial
considerations to allow for the cost of finance and tax.
Engineering and cost estimations have been completed to a
+/-25% level of accuracy, consistent with a study of this
nature.
Liontown’s financial model estimated a post-tax NPV8%of
approx.A$1.12B, and IRR of 37%,which demonstrates that
the Project is economic at forecast prices.
Sensitivity analysis undertaken during the open pit and
underground optimisation demonstrates that:

Overall open pit size is insensitive to costs or slope
changes and mildly sensitive to price and recovery.

Open pit ore tonnes recoverable are moderately
sensitive to dilution, ore loss and recovery and slightly
sensitive to costs or slope angles.

Discounted cash flow for the Project is highly sensitive
to parameters that directly affect revenue (i.e.
commodity prices, recovery and exchange rate) and far
less so to other parameters.
The low sensitivity to cost variations provide reasonable
confidence in the Ore Reserve estimate. However, there is no
