Highlights
• Alkali Flats Claims position expanded to capture potential extension of eastern higher-grade
trend:
o 41 claims staked to support expansion drilling plans and bulk sampling for metallurgy.
o Positioned to capture projection of shallowing, higher-grade core identified in the MRE.
• Further positive lithium extraction results and short leach times from a second successful
heap leach scoping test:
o 64% to 79% lithium recovery from calcination roast and 8-day water column leach tests.
o Up to 68% lithium recovery within 24 hours.
o Improvement of roast and water leaching previous results from 66% to 79% recovery.
• Significantly lower levels of impurities in the leachate compared with sulfuric acid
extractions.
• Relatively low reagent usage with the lowest roast blend ratio achieving the highest
recoveries and no use of acid during the extraction process.
• Clearly identified potential for optimisation of parameters in future testing (e.g. reagent
ratios, temperatures and open circuit columns).
• Alkali Flats positive metallurgy results continue to provide flexibility for various processing
options.
• Ongoing metallurgical test work program is focused on further detailed mineralogy mapping
and high-resolution lithium distribution, beneficiation and extraction optimisations.
Fulcrum Lithium Managing Director, Scott Keenan, commented:
“Alkali Flats is rapidly developing into a genuine growth story for Fulcrum. Following our maiden
resource of 10.7Mt LCE, already one of the largest lithium deposits in the United States, we are now
focused on expanding the project, with a future drill program being planned to grow the higher-
confidence, higher-grade core of the deposit, which already stands at 1.92Mt LCE above a 700ppm
lithium cut-off.
Complementing this growth strategy, our metallurgical program continues to advance along multiple
extraction pathways, with this round successfully demonstrating the feasibility of a second early heap
leach feasibility test, which was an acid-free extraction that delivered far lower impurities.
Encouragingly, the highest recoveries trend to the shallower, higher-grade south-east of the deposit,

the same area we are prioritising for resource growth and likely target focus for potential early pit
locations.
Together, with the potential for an expanding resource and advancing metallurgy create a very exciting
outlook for Alkali Flats.”
The Directors of Fulcrum Lithium Ltd (ASX: FUL, Fulcrum or the Company) are pleased to provide an update on
the project expansion and ongoing metallurgical testing for the Company’s wholly owned Alkali Flats project in
Esmeralda County, Nevada, USA (Figure 5).
Alkali Flats Project Expansion
Fulcrum has completed the staking of 41 lode claims on the eastern side of the existing claims boundary (Figure
1) to extend the Company’s prospective and commanding footprint of the Alkali Flats Basin. The area captured,
was targeted using lithium grade and structural trends observed from the geologic and resource modelling that
underpinned the maiden Mineral Resource Estimate (MRE)3, as well as additional basin geological knowledge
from the company’s extensive exploration of the basin since listing4,5 (Figure 2). The new number of claims for
the project stands at 698, after the company reshaped the claims to relinquish areas that did not contain
resource potential around the margins of the claims boundary following the MRE work. The number of claims
renewed for the 2026/2027 USA Bureau of Land Management (BLM) lease maintenance year were reduced
from 802 to 657, prior to the staking of these additional 41 claims.
The new claims will support future plans for drilling at the project, as part of the Company’s focus on the
potential to extend the higher confidence, higher grade portion of the resource currently defined in the Alkali
Flats MRE (Figure 3). The higher-grade portion of the resource above the 700ppm Li cut-off, is estimated at a
total combined resource of 1.92Mt LCE at an average grade of 775ppm (Table 4 and Figure 7).

Alkali Flats Metallurgy Program
Following the success of the first two series of tests in the Company’s initial metallurgical program1,2, where
excellent lithium extractions from sulfuric acid mini-column heap leach scoping tests achieved between 93%-96%
recoveries, 3 composite samples were selected for further testing by Kappes, Cassiday and Associates (KCA) in
Reno, Nevada, to test heap leaching with water on roasted samples.
The composite samples were constructed from cuttings samples taken every 1.5m over broad, 30m zones of
varying lithium (Li) grades from 3 reverse circulation (RC) drill holes, AF2-2, AF2-5 and AF2-10, completed during
the Alkali Flats Phase 2 drill program and returned average lithium grades up to 674ppm Li (Table 1).
Roast Calcination and Water Leach Mini-Column Tests
Clay samples were pulverized and pelletized with a 5:1:1 blend ratio of sample, gypsum, limestone using water.
The pellets were roasted at 1,000°C for 1 hour at atmospheric pressure. 1kg of pellets were placed in a 75mm
diameter column under a deionized water drip for 8 days in a closed-circuit, where the effluent was recycled as
feed solution. Measurements of the leachate solution were taken every 24 hours to track the progress of clay
material lithium extraction. After the leach period, the columns were drained and washed with deionized water.
The final leachate, wash solutions and tailings were assayed for lithium and other elements to determine the
percentage of lithium that was extracted from the clay pellets and the elemental composition.
From the 3 tests on the different zones, a range of 64% to 79% lithium extraction was achieved, with the majority
(up to 68%) extracted within the first 24 hours, when the first sample was assayed. From the lithium extraction
trend over time, after the first 24hrs, when the pregnant leach solution effluent begins being recycled as feed
solution in a closed circuit set up, no further significant extraction occurs. Significantly, when the final wash with
de-ionized water is applied to the columns (the final sample at hour 192), a 7%-10% final increase in the lithium
extraction is recorded, suggesting the potential for improvements in the process under an open circuit set up,
where fresh de-ionized water is applied daily.
Elemental analysis from the assays of the final leachate solution was performed to measure the concentrations
of other elements reflecting the level of impurities in the leachate solution (Table 2). A large reduction in
impurities compared to the results from the sulfuric acid leach tests were achieved, with over 99% reductions in
Aluminium (Al), Iron (Fe), Magnesium (Mg), Manganese (Mn) and Titanium (Ti).
Comparatively, the lithium extraction results from these mini-column tests were an improvement from the roast
and water leach previously performed in an agitated beaker, up from 66% to 79%. Although lower lithium
recoveries than the sulfuric acid mini-columns (93-96%), the offsetting benefits of an acid-free leach with far
lower impurities provide significant positive attributes that will be considered while assessing a variety of
potential process flows. The highest lithium extraction values were increasing towards the east of the resource
where the higher grade, shallower zone of the resource is located. Another positive trend in regard to the reagent
usage for the roast calcination and water leach testing is that the highest lithium extraction levels have been
observed from the lowest reagent ratio (5:1:1), suggesting there is opportunity to optimise this further with lower
ratios of gypsum and limestone which is scheduled for future testing.

Forward Plan
The Alkali Flats Project near-term forward plan is to continue to advance the metallurgical program, focusing on
further understanding detailed mineralogy and high-resolution lithium distribution, advanced beneficiation
techniques and extraction optimisations. Data from this initial scoping level metallurgical testing program from the
Phase 2 RC drilling program is being used as input for the currently ongoing testing and metallurgical program
planning on Phase 3 core and cuttings material.
Fulcrum is concurrently focusing on defining drilling options that provide potential to extend the higher
confidence, higher grade portion of the resource currently defined in the Alkali Flats MRE. The higher-grade
portion of the resource above the 700ppm Li cut-off, is estimated at a total combined resource of 1.92Mt LCE at
an average grade of 775ppm (Table 4 and Figure 4).

Alkali Flats Project
The Company owns a 100% interest in the Alkali Flats lithium project comprising 698 lode claims (approximately
58km2) located within the Esmeralda County on Federal public lands owned and administered by the United
States government. The project is situated approximately 15km south of the Tonopah Flats (American Battery
Technology Company) and TLC (American Lithium Corporation) lithium projects and 10km east of the Silver Peak
(Albemarle Corporation) lithium mine, the only operating lithium mine in the USA (Figure 5).
Across 3 phases of drilling from December 2024 to March 2026, Fulcrum has drilled 63 holes, comprising of 58
Reverse Circulation (RC) and 5 diamond drill cores, and acquired 25km of Controlled Source Audio
Magnetotelluric (CSAMT) geophysical data (Figure 2) which has discovered and appraised the Alkali Flats lithium
deposit, and is the foundation for the maiden MRE, of 10.7Mt LCE (total measured, indicated and inferred)
(Table 3) delivered within 12 months from discovery, announced on August 4, 20263. The Alkali Flats project
large-scale lithium resource ranks highly in total resource size as both a US domestic lithium resource (ranking
7th), as well as a reported MRE by ASX listed lithium exploration companies (ranking 3rd)3.

JORC Code, 2012 Edition – Table 1
Section 1 Sampling Techniques and Data – Alkali Flats Phase 2 Scoping Metallurgy
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 RC drill cuttings samples were acquired every five feet
(1.524 metres) collected from fluid and cuttings passed through
a cyclone sample collector. Buckets were lined with pre-labelled
bags. Sample bags and chip trays were pre-labelled for field
staff. A Fulcrum geologist collected the samples or trained the
rig sampler in methods. Field personnel monitored the drilled
depth, and drilling was briefly paused at the end of each sample
run to circulate the cuttings to surface. Each sample interval was
logged at the rig by the supervising geologist. Samples were
stored at the drill sites until pickup.
RC samples were weighed, dried, combined and pulverised to
form composite samples over intervals up to 30m wide for
metallurgical testing.
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).
• Not applicable for metallurgical reporting.
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.
• Not applicable for metallurgical reporting.
•
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 costean, channel, etc) photography.
• The total length and percentage of the relevant
intersections logged.
• Not applicable for metallurgical reporting.
•
Sub-sampling
techniques and
sample
preparation
• If core, whether cut or sawn and whether quarter, half
or all core taken.
• If non-core, whether riffled, tube sampled, rotary split,
etc and whether sampled wet or dry.
• For all sample types, the nature, quality and
appropriateness of the sample preparation technique.
• Quality control procedures adopted for all sub-sampling
stages to maximise representivity 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.
• Whether sample sizes are appropriate to the grain size
of the material being sampled.
• Not applicable for metallurgical reporting.

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.
• 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.
• Nature of quality control procedures adopted (eg
standards, blanks, duplicates, external laboratory
checks) and whether acceptable levels of accuracy (ie
lack of bias) and precision have been established.
Samples were analysed by Kappes Cassiday and Associates. of
Reno, Nevada by a number of different industry standard
techniques including below;
• 4-Acid, ICP-OES
• LECO,
Verification of
sampling and
assaying
• The verification of significant intersections by either
independent or alternative company personnel.
• The use of twinned holes.
• Documentation of primary data, data entry procedures,
data verification, data storage (physical and electronic)
protocols.
• Discuss any adjustment to assay data.
Sample intervals were assigned a unique sample identification
number prior to sample dispatch.
• Lithium-mineralised claystone CRMs, duplicates and blanks were
inserted into the sample stream at regular intervals to monitor
lab accuracy and potential contamination during sample prep
and analytical processes.
Location of data
points
• Accuracy and quality of surveys used to locate drill holes
(collar and down-hole surveys), trenches, mine workings
and other locations used in Mineral Resource
estimation.
• Specification of the grid system used.
• Quality and adequacy of topographic control.
Fulcrum geologists used handheld Garmin GPS units to record
sample location sites and as QC. Fulcrum geologists have
recorded the sample sites using NAD 83 Zone 11 datum.
Location of data points is considered to be at acceptable levels
of accuracy and precision.
Data spacing and
distribution
• Data spacing for reporting of Exploration Results.
• Whether the data spacing and distribution is sufficient
to establish the degree of geological and grade
continuity appropriate for the Mineral Resource and Ore
Reserve estimation procedure(s) and classifications
applied.
• Whether sample compositing has been applied.
• For Phase 2 drilling, drill holes were spaced 1500m-2500m
apart. The spacing is considered adequate for this stage of
exploration given the flat to moderately dipping sedimentary
layers.
Orientation of
data in relation to
geological
structure
• Whether the orientation of sampling achieves unbiased
sampling of possible structures and the extent to which
this is known, considering the deposit type.
• If the relationship between the drilling orientation and
the orientation of key mineralised structures is
considered to have introduced a sampling bias, this
should be assessed and reported if material.
• For Phase 2 drilling, drill holes were drilled vertical achieving
unbiased sampling of the underlying structure. The stratigraphy
comprises flat, bedded, mostly sedimentary layers.
Sample security • The measures taken to ensure sample security. RC samples remained in the custody of Fulcrum onsite at the
drill rig until collected by American Assay Laboratory personnel
and transported securely to their laboratory. Samples were
accompanied by submittal sheets. No security issues are
suspected. RC samples were stored at AAL prior to dispatch to
KCA laboratories.
Audits or reviews • The results of any audits or reviews of sampling
techniques and data.
• No audits or reviews of the data management system have been
carried out.

•
Exploration done
by other parties
• Acknowledgment and appraisal of exploration by other
parties.
• Not applicable as no exploration done by other parties is reported.
Geology • Deposit type, geological setting and style of
mineralisation.
• The Fulcrum Projects are in areas favourable for claystone hosted
lithium deposits. Project areas were selected based on the presence
of favourable host lithologies within hydrogeological closed basins
that also exhibited high geothermal activity. Fulcrum’s Projects are
geologically similar to other nearby lithium projects in the Tonopah
area with advanced exploration programs. Several of those projects
are currently being investigated at various exploration or
development stages all based primarily on the United States
Geological Survey (USGS) lithium depositional model as presented
by Asher-Bolinder (1991) in which three diagenetic models are
proposed for formation of enriched lithium clays in closed basins:
• Alteration of volcanic glass to lithium-rich smectite.
• Precipitation from lacustrine waters.
• Incorporation of lithium into existing smectites.
Drill hole
Information
• A summary of all information material to the
understanding of the exploration results including a
tabulation of the following information for all Material
drill holes:
o easting and northing of the drill hole collar
o elevation or RL (Reduced Level – elevation above sea
level in metres) of the drill hole collar
o dip and azimuth of the hole
o down hole length and interception depth
o hole length.
• If the exclusion of this information is justified on the
basis that the information is not Material and this
exclusion does not detract from the understanding of the
report, the Competent Person should clearly explain why
this is the case.
• For Phase 2 drilling a total of 10 holes planned at the Alkali Flats

Data aggregation
methods
• In reporting Exploration Results, weighting averaging
techniques, maximum and/or minimum grade
truncations (eg cutting of high grades) and cut-off
grades are usually material and should be stated.
• Where aggregate intercepts incorporate short lengths of
high grade results and longer lengths of low grade
results, the procedure used for such aggregation should
be stated and some typical examples of such
aggregations should be shown in detail.
• The assumptions used for any reporting of metal
equivalent values should be clearly stated.
• Not applicable for metallurgical reporting.
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 Siebert Formation is generally flat (<5 degrees) in the drilled
target. All holes are vertical, therefore all reported mineralisation
widths will be very similar to the interception lengths quoted and
the difference will be negligible.
Diagrams • Appropriate maps and sections (with scales) and
tabulations of intercepts should be included for any
significant discovery being reported. These should
include, but not be limited to a plan view of drill hole
collar locations and appropriate sectional views.
• Appropriate diagrams are included in the ASX announcement.
