ASX Announcement - 11 October 2024

San Jorge Lithium Brine Project - Update

Greenwing Resources Ltd (‘Greenwing’ or the ‘Company’) (ASX:GW1) is pleased to provide an update on its San Jorge Lithium Brine Project in Argentina. The Company released the maiden Mineral Resource Estimate for the project in May 2024, containing 1.07 Mt of Lithium Carbonate Equivalent (LCE) - 0.67 Mt of Indicated Resources and 0.4 Mt of Inferred Resources[1] . Greenwing sees considerable potential at San Jorge with the Maiden resource open in several directions and at depth.

HIGHLIGHTS

  • Completion of further surface exploration work at San Jorge providing additional confirmation of likely resource extension.

  • Considerable scope for further drilling in the exploration target defined in May and beneath the current resource to potentially add tonnes at a higher average grade.

  • MT (Magnetotellurics) and TEM (Transient Electromagnetic Method) electrical geophysics confirm the brine body extending more than 4 kilometres west of the salar boundary.

  • MT shows the brine body has a thickness up to 600m west of the salar, confirming substantial potential west of the Mineral Resource. The deepest hole drilled to date (SJDD04) reached 402m, ending in brine with 248 mg/l Li.

  • Greenwing is planning Phase 2 drilling to test the exploration target to the west of the Mineral Resource, with drilling sites selected and access road locations to be finalised.

EXECUTIVE DIRECTOR / CEO, PETER WRIGHT:

"I am very pleased with the results from our initial exploration program. In addition to establishing a maiden resource in one of the world's prolific lithium jurisdictions we have set a platform to add value to the San Jorge Project. We have established all necessary infrastructure at site, built an experienced team, and attracted a fantastic partner in NIO Inc. Above all else, we have a well-articulated pathway to add lithium tonnes to the maiden mineral resource declared.

The current resource is open to the West, the North and at depth. Both holes SJDD04 and SJDD05 saw an increase in grade from surface to circa 248 mg/L at 360 and 314m respectively. We have completed 6 holes, with Phase 2 planned to contain 7 further diamond holes for resource definition. This will be followed by installation of wells for test pumping, to unlock the exciting potential of the San Jorge Project, in a basin which has been unappreciated to date.”

PHASE 2 DRILLING PROGRAM

Figure 3 (below) shows the location of the Phase 1 drilling, the resource and exploration target.

Figure 4 shows the TEM and MT geophysics, with Figure 5 showing the MT profile looking north through the north of the salar, showing conductive brine continues west of the salar and north of where the salar is widest. This confirms the potential shown in the exploration target announced 27 May 2024.

Greenwing is planning for the Phase 2 drilling program, which is anticipated to include approximately 7 drillholes to 400 m or deeper. Drilling (Figure 3) is aimed at defining resources in the exploration target defined west and north of the Maiden Resource, centred around the salar. Drill sites would be primarily accessed from the west of the salar, with some holes drilled on the salar from raised roads.

PROJECT BACKGROUND

The initial drilling program (Table 1) completed in May 2024 established the geology and brine distribution of the San Jorge project, drilling technically easier holes on the eastern and western peripheries of the visible 2,800 Hectare San Francisco salar.

This program was preceded by a surface geophysics campaign which indicated basin depths of circa 400m +/- 200m. The initial 6 hole program has exceeded expectations and delivered a maiden mineral resource estimate of 1.07 Mt LCE, as indicated (0.67 Mt) and Inferred Resource (0.4 Mt)[2] . The initial resource has excellent overall porosity (specific yield) averaging 7.4% for the geological units. In addition, an exploration target[2] of between 0.37 and 1 Mt LCE has been defined, which will be drilled in the Phase 2 program, to confirm brine and porosity characteristics.

The drilling on the eastern periphery of the salar has established the eastern extent of mineralisation, as outcropping basement rock, which dips west under the salar and becoming progressively deeper from approximately 120 m in the eastern holes (SJDD02, 03 and 06). The lithium concentration increases progressively with depth in all of the holes, suggesting this trend could continue west and north of the salar.

The resource remains open to the west and north and at depth in volcanic and sedimentary units. The brine also continues into the fractured basement rocks, although this has not been considered in quantification of the brine volume. Holes SJDD04 and SJD005, which reached depths of 402m and 352m respectively, both ended in brine mineralisation and delivered substantial continuous mineralised brine from within several metres of surface to the end of the holes. Both holes delivered material increases in lithium grade (increasing from 155 to 248 mg/l) as depth increased.

Earlier this year the Company completed an extensive surface program of additional passive seismic measurements, which provided information regarding the probable depth to the older basement rocks. An additional program of TEM (Transient Electromagnetics) and MT (magnetotellurics) is now largely complete. This confirms the western and northern extension of the brine body, with brine extending approximately 4 km or more west of the salar margin (Figures 4 and 5).

Having established a Maiden Resource Estimate and comprehensive data set the Company is well placed to continue progress at San Jorge, with many of the most prospective areas of the project yet to be drill-tested.

In Argentina the Lithium triangle hosts only 24 salars. Greenwing is one of a select group of companies which have rights to 100% of a salar and extensive surrounding area. From this initial program Greenwing has established a strong platform to continue to add significant value to the project, as the market for lithium recovers.

PROJECT LOCATION AND EXPLORATION LICENSES

Catamarca Province is one of three provinces in the north of Argentina that host globally significant resources of lithium in brine, beneath salt lakes (salars).

Extraction of lithium from brine has a lower overall carbon-footprint than from hard rock operations, as the brine is already dissolved and ready for extraction. Brine is a key source of lithium for the global economies ongoing transformation to a lower carbon intensity, with the electrification of transportation and the development of large-scale battery storage to accompany renewable energy generation. Importantly, producing lithium product from brine is also cheaper than from hard rock (spodumene or lepidolite) or lithium in clays.

The San Jorge project (Figures 6 and 7) covers 2,800 hectares of the San Francisco salar, near the border of Argentina with Chile. Greenwing has the sole rights to all mining tenure on the salar and 36,000 hectares of surrounding ground in 15 granted exploration licenses. This property holding provides Greenwing with control over activities on the salar, with no third-parties present, unlike in most other salar basins.

The Company has the right to acquire up to 100% of the San Jorge Lithium Project (Figure 6) entirely at its election on satisfaction of investment and expenditure commitments. The Company’s current interest in the project is 45%.

The San Jorge Project (Figure 7) is located in the Lithium Triangle along with major lithium mining and development companies including Zijin Mining, Arcadium (formerly Allkem and Livent), Ganfeng, Rio Tinto, Lake Resources and Galan Lithium.

PHYSIOGRAPHY, CLIMATE, AND ACCESS

The San Jorge project is located at close to 4,000 m altitude at the southern end of the high-altitude desert that is the Puna Plateau in the north of Argentina. This environment is characterised by freezing nights and cool days, with high solar radiation and common wind, which is often strong and gusty. These conditions result in very high evaporation rates, which concentrate surface and groundwater as it flows into the salar. resulting in high total dissolved solids in the resultant brine, with elevated concentrations of lithium and other elements, such as potassium, sodium and magnesium. There are significant freshwater inflows into the basin, which is considered positive for supporting brine processing for production.

The San Jorge project covers the San Francisco salar, and the surrounding slopes, that lead from a series of major stratovolcanoes on the border with Chile, to the salar. These slopes are covered by gravel and basalt lava flow. These volcanoes reach to 6638 m on the limits of the catchment area and dominate the skyline of the project, generating rainfall runoff and infiltration from snow melt, towards the salar.

ASX:GW1 | greenwingresources.com Greenwing Resources Ltd ABN 31 109 933 995

For the remote location of the project, the access is excellent, as it is located adjacent to the international road leading to the San Francisco Pass with Chile. This road is paved from the capital city of Catamarca through the project, and into Chile (where there is a gravel interval). This road provides access for supplies in Catamarca province and Argentina and Chile, where the road crosses beside the Maricunga salar, providing access to ports in the Antofagasta region, from where existing lithium carbonate suppliers export product to Asia and chemicals for processing are imported.

The border post adjacent to the project consists of a customs facility, border police station, medical clinic and road maintenance depot. There is a mobile phone tower at the border facility, which allows communication through parts of the project area.

FUTURE ACTIVITIES

The Company is continuing to collect environmental data in the project area, to support the future project EIA preparation and submission.

Planning of road access to Phase 2 drilling projects is underway.

The Company will continue to evaluate various Direct Lithium Extraction service offerings.

Discussions are progressing in relation to securing funding, to advance the project to the feasibility stage, with expanded drilling and processing test work.

(Criteria in this section apply to all succeeding sections.)

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.

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.

The pre-collars from surface were drilled using
the Tricone drilling method, and cuttings were
logged as collected, to 30 m below surface.

The pre-collar was then cemented in, and HQ
Core drilled.

Core recovery from the HQ was carefully
measured by comparing the measured core to
the core runs and then a total recovery per
section determined.

HQ Drill core sampling was undertaken to
obtain representative samples of the
stratigraphy and sediments that host brine (with
a vertical spacing of 12 m), for porosity testing
and evaluation of specific yield, the brine that
could be extracted.

Brine samples were collected every 18 m
(where possible) using an inflatable single
packer sampling equipment (typically used in
geotechnical evaluations) as the hole is
deepened. Brine samples are used for lithium
analysis, with the lithium dissolved in the brine
hosted in pores within core samples.

Porosity samples are collected in Lexan
polycarbonate tubes during the drilling, with
cores between porosity samples (taken every
12 m) collected in triple tubes and stores in
core boxes.

Conductivity and Density measurements are
taken with a field portable High Range Hanna
multi parameter meter and floating
densiometers.

Testing of the chemical composition (including
Lithium, Potassium, Magnesium concentrations
and those of other ions) of brines are
undertaken at a local laboratory in Argentina.

Transient Electromagnetic (TEM) geophysics
was previously undertaken on the surface of
the salar and surrounding area. The Transient
Electromagnetic method (TEM) used a 200 x
200 m loop that is moved between stations
located 400 m apart on east west lines. The
lines are separated by 1000 m in the north-
south direction.

TEM has proven to be a highly applicable
technique in and around salars, as the method
avoids the surface conductivity issues
associated with resistivity methods, such as

ASX:GW1 | greenwingresources.com Greenwing Resources Ltd ABN 31 109 933 995

13

Criteria JORC Code explanation Commentary
Vertical Electrical Soundings or resistivity
profiling.

The TEM method has a lesser penetration on
the salar surface but sees through resistive
surface sediments and volcanics to define the
extension of brine beneath these units.

Highly conductive zones of <1 ohm m are
located beneath the salar surface, continuing
to the west under volcanic flow units,
surrounded by a zone of 1-3 ohm m resistivity.

Survey lines were oriented perpendicular to the
elongation of the salar.
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).

The pre-collars from surface were drilled using
the Tricone drilling method; chips were logged
as collected, to the pre-collar depth, which was
30 m in this hole.

The pre-collar was then cemented in (isolated)
and HQ Core drilled.

Core recovery from the HQ was carefully
measured by comparing the measured core to
the core runs and then a total recovery per
section determined.

HQ Drill core sampling was undertaken to obtain
representative samples of the stratigraphy and
sediments that host brine.

Drilling has been conducted using a diamond
drilling rig, with HQ drilling equipment. The hole is
drilled with the assistance of drilling mud. The
drilling produced cores with variable core
recovery, associated with unconsolidated
material, in particularly sandy intervals. Recovery
of these more friable sediments is more difficult
with diamond drilling, as this material can be
washed from the core barrel during drilling.

Brackish water to dilute brine, obtained from the
salar surface near the drill hole, has been used
as drilling fluid for lubrication during drilling, for
mixingof additives and muds.
Drill sample
recovery

Method of recording and
assessing core and chip sample
recoveries and results assessed.

Measures taken to maximise
sample recovery and ensure
representative nature of the
samples.

Whether a relationship exists
between sample recovery and
grade and whether sample bias
may have occurred due to
preferential loss/gain of
fine/coarse material.

Diamond drill core was recovered in 1.5m length
intervals in the drilling triple (split) tubes, and
Lexan polycarbonate tubes used in place of the
triple tubes, to obtain samples for the laboratory.
Appropriate additives were used for hole stability
to maximize core recovery. The core recovered
from each run was measured and compared to
the length of each run to calculate the
recovery. Chip samples, for any intervals drilled
with rotary drilling, are collected for each metre
drilled and stored in segmented plastic boxes for
rotary drill holes.

Brine samples were collected at discrete depths

interval (to isolate intervals of the sediments and
obtain samples from airlifting brine from the
sediment interval isolated between the packers)
open to the base of the hole. The separation of
packer samples shows some variability, due to
conditions during drilling.

Additives and muds are used to maintain hole
stability and minimize sample washing away
from the triple tube.

As the brine (mineralisation) samples are taken
from inflows of the brine into the hole (and not
from the drill core – which has variable recovery)
they are largely independent of the quality
(recovery) of the core samples. However, the
permeability of the lithologies where samples are
taken is related to the rate and potentially
lithium grade of brine inflows. Core recovery
from the HQ was carefully measured by
comparing the measured core to the core runs
and then a total recovery per section
determined.

No relationship exists between core recovery
and lithium concentration, as the lithium is
present in brine, sampled independently of the
core samples. Brine is extracted using packer
sampling and the sediment material is not the
target for lithium extraction.
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.

Whether logging is qualitative or
quantitative in nature. Core (or

The total length and

Volcanic derived sand, gravel, volcanic tuffs
and intervals of lava flows were recovered in

examined for geologic logging by a geologist,
with photographs taken for reference.

Diamond holes are logged by a geologist who
also supervised taking of samples for laboratory
porosity analysis (with samples drilled and
collected in Lexan polycarbonate tubes) as
well as additional physical property testing.

Logging is both qualitative and quantitative in
nature. The relative proportions of different
lithologies which have a direct bearing on the
overall porosity, contained and potentially
extractable brine are noted, as are more

qualitative characteristics such as the
sedimentary facies. Cores are photographed.

Downhole geophysical logging will be
undertaken by Zelandez, a Salta (Argentina)
based specialist Borehole Geophysical Logging
company, with several logging probes,
including, Calliper, Conductivity, Resistivity,
Borehole Nuclear Magnetic Resonance (NMR
or BMR), Spectral Gamma.

The BMR probe provides information of Total
Porosity, Specific Retention and Specific Yield.
The total porosity of a rock formation
represents the total pore space. Although Total
Porosity has two principal components,
Specific Retention and Specific Yield: (a)
Specific Retention (Sr), represents the portion of
the Total Porosity that is retained by clay and
capillary-bound sections of sediment. (b)
Specific Yield (Sy) is the amount of water/brine
that is available within the sediment for
groundwater pumping.

Specific Yield is a key parameter when
calculating a Lithium Brine Resource.

Physical samples of the core are also sent for
porosity laboratory analysis for measurements
of specific yield and total porosity. This
sampling is undertaken as a check on the BMR
geophysical logging, with a comparison of
variance and averages undertaken.
Sub-sampling
techniques
and sample
preparation

If core, whether cut or sawn and
whether quarter, half or all cores
taken.

If non-core, whether riffled, tube

whether sampled wet or dry.

For all sample types, the nature,

the sample preparation
technique.

Quality control procedures
adopted for all sub-sampling
stages to maximise
representativity of samples.

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.

Brine samples were collected by using an
inflatable packer to purge the hole of all fluid,
to minimise the possibility of contamination by
drilling fluid. The packer allowed sampling of
isolated sections of the hole every 18 m
(subject to hole conditions), allowing the
packer interval to re-fill with groundwater
following purging.

Samples were then taken from the relevant
section, with three well volumes of brine
purged where this was possible.

Field duplicate samples are collected in the
field. Single-packer samples are taken during
the progression of drilling. Once the hole is
completed, double packer samples will be
taken in an upward progression leaving the
hole, as a check on the initial single packer
samples.

Brine sample (0.5 litre) sizes are considered
appropriate to be representative of the

Geology
Deposit type, geological setting
and style of mineralisation.

The project is a salar deposit, located in a
closed basin in the Andean Mountain range in
Northern Argentina.

The sediments within the salar consist of
volcanic ash, silt, and volcanic flows locally,
and possibly at deeper levels sand, gravel
halite and or clay, which have accumulated in
the salar from terrestrial sedimentation from the
sides of the basin. Brine hosting dissolved lithium
is present in pore spaces.

The sediments are interpreted to be essentially
flat lying with unconfined aquifer conditions
close to surface and semi-confined to
confined conditions at depth.

Geology was recorded during previous
excavation of shallow pits for brine sampling.

minimum grade truncations (eg

Where aggregate intercepts

such aggregations should be
shown in detail.

The assumptions used for any
reporting of metal equivalent
values should be clearly stated.

Individual TEM soundings were recorded at
each site and later this information was
interpolated into sections, based on data from
individual stations.

No cutting of lithium concentrations was
justified nor undertaken.

Lithium samples are by nature composites of
brine over intervals of metres, due to the fluid
nature of brine.
Relationship
between
mineralisation
widths and
intercept
lengths

These relationships are
particularly important in the
reporting of Exploration Results.

If the geometry of the
mineralisation with respect to
the drill hole angle is known, its
nature should be reported.

If it is not known and only the
down hole lengths are
reported, there should be a
clear statement to this effect
(eg ‘down hole length, true
width not known’).

The sediments hosting brine are interpreted to
be essentially flat lying. The entire thickness of
sediments has the potential to host lithium
brine, with the water table within
approximately 0.3 metre of surface on the
salar.

Mineralisation is interpreted to be horizontally
lying and drilling is perpendicular to this, so
intersections are considered true thicknesses
Brine is likely to extend to the base of the basin
and has been confirmed by drilling to extend
into fractures in the underlying older
bedrock/basement units of fractured
sandstones.

Mineralisation is continuous between drill holes.

The project is a salar/salt lake project, where
lithium has been concentrated in brine through
evaporation,

The salar is approximately 11 km in the longest
dimension and approximately 3 km wide in the
west-to-east direction.

There is a relatively high level of confidence in
the geological interpretation for the Project,
with five geological units identified in the
logging and down hole geophysics. There are
consistent across the project area and thicken
from east to west. Lithological units consist of
volcanic tuffs, generally highly brecciated
basaltic to Andesitic lava flows, reworked
volcanic-sedimentary material and intervals of
ignimbrite.

Any alternative interpretations are restricted to
smaller scale variations in sedimentology,
related to changes in grain size and fine
material in units, or a larger scale grouping of
sediments, as changes between units are
relatively minor. Such changes would not have
a significant impact of the resource estimate.

Data used in the interpretation includes rotary
and diamond drilling methods.

Drilling depths and geology encountered has
been used to conceptualize hydro-stratigraphy
and build the model units.

Sedimentary processes affect the continuity of
geology with extensive lateral continuity in the
salar area, and the presence of additional

lake.
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.

The lateral extent of the resource has been
defined by a 3 km radius of influence around
the drill holes, which is extended slightly
beyond 3 km in the south of the salar. The 3 km
was chosen as a more conservative distance
around drillholes than the Houston et. al., 2011
paper suggests as possible influences for
Indicated and Inferred classification. The five
geological units show a consistent correlation
between drillholes over distances consistent
with the 3 km radius around drillholes, with the
exception of the lower part of SJDD01.
Correspondingly the area around SJDD01 is
classified as Inferred.

The brine concentration increases down hole.

The area covered by the maiden resource is
49.2 km2, with the exploration target covering
an additional 34.04 km2.

The top of the model coincides with the
topography obtained from the Shuttle Radar
Topography Mission (SRTM), locally adjusted for
each drillhole collar with the most accurate
coordinates available. The base of the
resource is limited to the basement depth
intersected in drilling, or interpreted from
passive seismic and TEM geophysics. To date
the basement rocks have only been
intersected in the east of the project area.

The indicated resource is defined to a
maximum depth of 400 m below surface,
inferred resource below 400m and with the
exploration target extending beyond the areal
extend of the resource. Brine that extends into
fractures in the basement rock is not
considered in the resource.

method was used to estimate the distribution

smaller number of assays available, compared
with porosity measurements.

The resource with a 3 km radius was estimated
in three passes. As the classification is based on
the geological continuity and confidence in
the interpretation the estimation is not directly
tied to the passes, but to the drill hole

respectively.

Five hydrostratigraphic units (including the
Permian basement) were defined in the salar
area, based on geological logging and
downhole geophysics. These show a dip
towards the west, where they are thicker, and
where the accumulation of a thicker sequence
may have been aided by subsidence along
faults in that area of the basin. The Permian
basement is not included in the resource
estimate, although it does contain brine hosted
in fractures.

The resource was estimated with soft
boundaries for the lithium and other chemical
elements and a horizontal search ellipse.
Lithium concentration appears independent of
the geological units.

The resource was estimated with hard
boundaries between the geological units, as
the specific yield can be significantly higher in
Unit 4 (volcano sedimentary unit), compared
to Unit 2 (brecciated basalt flows). No dip was
applied to the search ellipse..

No grade cutting or capping was applied to
the model, as there are no significantly higher
lithium concentrations.

For the specific yield porosity, all values above
30% were removed, as this is considered to be
an extremely high value for the units
encountered in drilling. The results of the BMR
geophysical profiles and the laboratory
porosity values where cross-checked and
where significant differences were

The brine contains other elements, such as
magnesium and sodium, in addition to lithium.
These can be considered deleterious elements.
The project plan considers extraction of lithium
via a DLE (Direct Lithium Extraction) process,
where extraction of lithium is independent of
other elements, which remain in the brine.

Model blocks are defined as 200 by 200 m
blocks in an east-west and north-south
direction and 20 m in the vertical direction. The
vertical spacing of brine samples averaged
approximately 28 m between samples, with the
average distance between holes of
approximately 2.4 km.

The brine composition is relatively
homogeneous and selective mining would be
difficult and is not necessary in this project, as
the resource is relatively homogeneous.

Visual comparison has been conducted of drill
hole results and the block model, together with
a comparison of sample statistics and the
block model statistics. The result is considered
to be acceptable.

Based on the packer measurements,
confirming the presence of suitable
permeability for brine pumping and the
advances in development of DLE technology
there are considered to be reasonable
grounds for eventual economic extraction.

content is not relevant for the brine resource
estimation.

Tonnages are estimated as metallic lithium
dissolved in brine.

density estimates used in the
evaluation process of the
different materials.

Density measurements were taken as part of
the drill core porosity assessment. This included
determining dry density and particle density as
well as field measurements of brine density.

Note that no mining of sediments and rock is to
be carried out in the project. Lithium extraction
would be by pumping brine from wells installed
in the salar sequence and pumping the brine
to the processing plant.

Density measurements are not directly relevant
for brine resource estimation.

No bulk density was applied to the estimates
because resources are defined by volume,
rather than by tonnage.
Classification
The basis for the classification of
the Mineral Resources into
varying confidence categories.

Whether appropriate account
has been taken of all relevant
factors (i.e. relative confidence
in tonnage/grade estimations,
reliability of input data,
confidence in continuity of
geology and metal values,
quality, quantity and distribution
_of the data). _

The resource has been classified into resource
categories based on confidence in the
estimation.

Indicated Resources defined in the project are
within 3 km of drill holes and to a maximum
depth of 400 m. I

The Inferred resource is defined around drillhole
SJDD01 in the northwest of the resource area.

Inferred resource is also defined below 400 m
depth, in addition to the area around SJDD01.

Commentary

Whether the result appropriately
reflects the Competent Person’s
view of the deposit.

It is expected that with further drilling at least a
portion of the Inferred resources can be
converted to Indicated resources.

To the north and west of the resource area an
Exploration Target has been defined. This is
constrained by the area where passive seismic
and TEM electrical geophysics have been
completed, with additional TEM completed in
this area,
Audits or
reviews

The results of any audits or
reviews of Mineral Resource
estimates.

Where appropriate a statement
of the relative accuracy and
confidence level in the Mineral
Resource estimate using an
approach or procedure
deemed appropriate by the
Competent Person. For
example, the application of
statistical or geostatistical
procedures to quantify the
relative accuracy of the
resource within stated
confidence limits, or, if such an
approach is not deemed
appropriate, a qualitative
discussion of the factors that
could affect the relative
accuracy and confidence of
the estimate.

The statement should specify
whether it relates to global or
local estimates, and, if local,
state the relevant tonnages,
which should be relevant to
technical and economic
evaluation. Documentation
should include assumptions
made and the procedures used.

These statements of relative
accuracy and confidence of
the estimate should be
compared with production
data, where available.

Estimation of the Mineral Resource was
supervised by the Competent Person. An audit
has not been carried out, although the data
used for the estimate has been reviewed
directly by the Competent Person. Discussions
about different geological and modelling
scenarios and search criteria were held and
check estimates were reviewed by the CP.

An additional estimate of the resource was
completed using a Nearest Neighbour
estimate.

Visual inspection against samples in the model,
and evaluation of sample and block statistics
was undertaken as a check on the model and
results are considered to be reasonable.

Estimation for Brines.

Brine resources are defined with less drilling
than most metalliferous deposits, but are
generally relatively homogeneous lithium
concentration, although porosity and
permeability are specific to different
geological units. Consequently, there is
uncertainty associated with the brine
estimate.
