  • The Upgraded Mineral Resource represents a further significant expansion of Anson’s lithium JORC Mineral Resource inventory in the Paradox Basin

  • Potential for substantial further Mineral Resource expansion – Western Strategy drilling

Anson Resources Limited (ASX: ASN) (Anson or the Company) is pleased to announce a major upgrade to its JORC Code 2012 Mineral Resource estimate (Mineral Resource), to 1.5 million tonnes of lithium carbonate equivalent (LCE) (refer to Tables 1 and 2 below), at its Paradox Lithium Project (Project) in south-eastern Utah, USA.This represents a major step-change increase in Anson’s JORC Mineral Resource inventory at its Paradox Basin lithium assets, and a significant milestone in the development pathway of the Paradox Lithium Project.

The Mineral Resource upgrade comes after the Company advises it has successfully completed the acquisition of the Green Energy Lithium Project from Legacy Lithium Corporation (ASX Announcement 18 July 2023). The Green Energy Project is strategically located immediately adjacent to the Paradox Project, and increases the Project area by 8% to a total of 231.35 km[2] . It hosts 18 historic oil and gas wells – three of which have recorded lithium values – which has enabled Anson to deliver this Mineral Resource increase without the need for further drilling.

The new, upgraded JORC Mineral Resource is;

  • 1,504,237 tonnes of lithium carbonate equivalent (LCE) and 7,608,700 tonnes of bromine, including,

  • Indicated Resource of 366,737 tonnes of LCE and 1,910,000 tonnes of bromine; and

  • o Inferred Resource of 1,137,500 tonnes of LCE and 5,698,700 tonnes of bromine

Further Mineral Resource Expansion Potential

Anson is building a world-class JORC Mineral Resource inventory at its lithium assets in the Paradox Basin in Utah.

At the Paradox Lithium Project, future drilling of the “Western Strategy”, if successful, would significantly increase the brine tonnages based on the thicknesses of those units, as determined from historical oil exploration drilling in the area (ASX Announcement 5 October 2022).

In addition, the Big Flat Unit 2 well, within the acquaried Green Energy Project, see Figure 1 for the well location, has a known historical value of 173ppm lithium for the Clastic Zone 31 horizon. The reentry of this well, if successful, would further increase the brine tonnage based on similar thicknesses which would support either an extension of the life of mine or a possible production increase. An internal review considering these options and whether to continue with further drilling programs in the immediate future to increase the JORC Mineral Resource estimate is currently underway.

It should be noted that Anson plans to commence a JORC Mineral Resource definition drilling campaign at its Green River Project, located 50kms northwest of the Paradox Project. The Green River Project exhibits outstanding geological characteristics, which indicate its strong potential to deliver additional JORC Mineral Resources (ASX Announcement 2 October 2023).

Anson’s Executive Chairman and CEO, Bruce Richardson commented, “The acquisition of the Green Energy Project from Legacy and the corresponding increase in the JORC Resource estimate is a milestone achievement for Anson. The discovery and development of this world class resource in the United State of America at this point in time is signficicant and a credit to the whole Anson team and in particular its geologist and consultants. This increase in resource has been achieved without needing to re-enter a well and the incur the related expenditure. The Company is working vigorously to bring the Paradox Lithium Project into production and will continue provide updates to the market as the Project develops.”

The following information and tables are provided to ensure compliance with the JORC Code (2012) requirements for the reporting of Exploration Results and Mineral Resources for the Paradox Brine Project. Please also refer to JORC Tables 1, 2 and 3 below.

Geology and geological interpretation

The brine bearing units, clastic zones, have been interpreted from more than 100 oil and gas wells drilled throughout the Anson claims and the greater Paradox Basin. The lithological units have been correlated within the basin based on the drilling and are predictable over the whole basin. Twentyeight wells (refer table 5) were used to interpret the depth and thickness of these horizons within the Anson claims.

The reason for the presence of the supersaturated brines in the clastic breaks is that the clastic beds overlie rich potash and magnesium zones. In the geological concept of the evaporite cycle, the most soluble compounds are the last to precipitate. Therefore, the clastic units overlie end products of the preceding evaporite cycle. Potassium and magnesium chlorides and certain complex evaporite minerals can be found among the end products of evaporation.

The main brine zones in the project area have not been cored, but it has been adequately sampled and logged. There are four inter-bedded hydrogeological units within the clastic horizon from top to bottom:

  • Anhydite;

  • Black Shale;

  • Dolomite; and

  • Anhydrite.

The dolomite is quite porous and permeable, whereas the anhydrite and black shale is crushed and broken. When the zones containing brine are intersected during drilling, artesian flow begins which indicates vertical porosity, permeability and that communication exists between the layers. The fractured clastic zones form an excellent reservoir for supersaturated brines. At the extraction point, when brine is removed salt will flow into the voids from where the brine has been removed, due to these parameters. This would help maintain high reservoir pressure and assist in a high ultimate recovery of brine.

The three factors; high pressure, porosity (both horizontal and vertical) and shallow depth are key attributes of the Paradox Lithium Project and are not present anywhere else in the area. In combination, they provide strong indicators of low extraction costs and beneficial ESG outcomes.

The high flow rates from the four tested wells confirms this theory.

In the White Cloud No. 2 well, which offsets the Long Canyon No. 1 well, brine started to flow when the top anhydrite was penetrated, and rapidly increased by the time the underlying black shale was penetrated, so that no further drilling was done. The dolomite zone was not drilled. Vertical porosity, permeability, and communication are indicated. Brine flows have been encountered in Clastic Zone 31 over a distance of six miles north-south and eight miles east-west.

Previously the brine aquifer had been interpreted/limited to the dolomitic sands with known porosity and excluded the potential for brine fluids within the anhydrite and shale lithologies. Spinnerflowmeter logging completed in Long Canyon Unit 2 and Skyline Unit 1 suggests that these units produce brine fluids from secondary porosity, and that the brine aquifer within Clastic Zone 31 has dual porosity based on both lithology and secondary porosity from fracture flow. Therefore, the extent of the brine aquifer has been extended to include the entirety of the clastic zone for the purposes of exploration targeting and resource estimation.

Figures 2 and 3 illustrate the stratigraphy in the area of interest. Of importance is the correlation of the various sedimentary units between the wells. This correlation enables the clastic units of interest to be modelled over an extensive areal extent.

Brine Aquifer Hydraulic Properties

Porosity (or total porosity) is the amount of open space between mineral grains and/or fractures. Certain geophysical logs can be utilized to estimate total porosity with significant accuracy. Anson had previously analysed a small subset of these logs from wells within the project area to estimate porosity of the dolomite in Clastic Zone 31. Utilizing a combination of neutron density logs and sonic logs total porosity was estimated for three wells as shown in Table 3.

Spinner-flowmeter logging completed in Skyline Unit 1 and Long Canyon Unit 2 suggest that these units also produce brine fluids from a secondary porosity, and that the brine aquifer within Clastic Zone 31 has dual porosity based on both lithology and secondary porosity from fracture flow. Figure 6 shows the interpretation of a spinner flowmeter test completed across Clastic Zone 31 in Long Canyon Unit 2.

==> picture [407 x 211] intentionally omitted <==

Figure 6: Spinner flowmeter log across perforated CZ 31 in Long Canyon Unit 2, with interpretations.

The spinner-flowmeter log indicates there is significant brine production from both the silty dolomite and shale lithologies in Clastic Zone 31 of Long Canyon Unit 2. Lithological thickness vs. flow contribution suggests that the shale has a higher transmissivity than the silty dolomite, which based on known textural differences, suggests significant secondary porosity (fracturing) within the shale. Without secondary porosity from fracturing, the common range of effective porosity for shale ranges from 0.5 to 5% (Driscoll 1986), which would have a corresponding limit on the transmissivity of the lithology. The lack of brine production contribution in the upper silty dolomite is likely due to poorly developed perforations or backpressure on the system limiting the brine flow discharge rate within upper zones of lower transmissivity.

During the re-entry and the development of the perforated intervals within Skyline Unit 1 and Long Canyon Unit 2 wells, Anson completed build-up tests to estimate production interval permeability. Build-up tests consisted of a short period of measured flow, followed by an immediate shut-in of flow at the well head and measurement of the pressure recovery. See Table 4. The data was analysed to determine the permeability of the formation (Horner plot, see Figure 7).

Table 4: Results of the downhole flow and pressure testing at Long Canyon and Skyline well.

In general, permeability increases with increasing effective porosity and decreases with increasing pressure. However, secondary porosity in the form of fracturing increases the bulk permeability of a geologic unit, as well as increasing its sensitivity to effective pressure.

Table 5: Historic drill holes within or close to the Paradox Brine Project area.

The super-saturated brines, typically with a high density (1.25 - 1.30 g/cm3) have been intersected throughout the clastic zones of the Paradox Basin. Analytical results for lithium to date have been highest (up to 253ppm lithium) in the central to southern area of the project.

Effective Porosity

Effective porosity was measured from core in one well, Big Flat 2 by mercury injection. Test-work was carried out by Core Laboratories, Petroleum Services Division in Houston, Texas. During the mercury injection test, each clean dry sample was immersed in mercury in a pressure-sealed chamber. The pressure of the surrounding mercury was gradually increased from 0 psia up to 55,000 psia. The increasing pressure gradually forced the mercury to intrude into the sample pore spaces and the amount of mercury injected, expressed as a fraction of the sample pore volume, was determined. The relationship of injection pressure to mercury saturation was used to calculate several parameters, including pore throat size distribution, capillary pressure for various fluid systems, and Swanson permeability. The results for the effective porosity test-work are contained in table 6.

Clastic Zone 31 (CZ31) has been previously logged to extend from 1914.1m to 1917.2m. CZ31 is located between two halite/anhydrite units (salt cycles 15 and 16)1 so the examination of the chips here indicated that CZ31 may extend further to at least 1919 based on the geological description of shaly dolomite. The data within this zone is incomplete but the effective porosity for the missing interval has been estimated by averaging the results from either side of the non-sampled intervals. Clastic Zone 31 is considered to extend between zones where anhydrite has been logged and this corresponds to the interval 1914.4m to 1919.0m (highlighted in yellow in table). By estimating the missing intervals, the weighted average of effective porosity over a 4.6m width of CZ31 is 14.9%.

The neutron density log indicated a total porosity for CZ31 in the Big Flat 2 well of 21%. The ratio of total porosity to effective porosity in Big Flat 2 was applied to other data within CZ31 to estimate effective porosity in this clastic zone. Other clastic zones used an estimate of 14%. The other clastic zones are repeat sedimentary sequences with the Paradox Basin so hydraulic properties are assumed to be similar. Results of this can be found in Table 7.

Effective porosity in this case is essentially the same as drainable porosity as the re-entered wells at Cane Creek 32-1, Skyline and Long Canyon No2 all had high pressure flow to the surface with no pumping required.

Sampling and sub-sampling techniques

Anson has re-entered and sampled four wells within the claim area. Table 8 summarises the assay results from the brine analysis. The brine is under pressure so flows to the surface naturally. The Clastic Zone intervals were located through previous hole geophysical logs. Following perforation of the interval to be sampled, a mechanical packer was set below the interval to isolate the brine produced and prevent comingling of a sample. The open intervals were then developed by swabbing. Fluid produced from the swabbing process was collected in approximately 1,000 litre (L) clean, high density polyethylene (HDP) totes. Separation of oil and water occurred within the totes, allowing for decanted samples of the produced brine fluid to be collected from the totes. Samples were collected into clean polyethylene bottles, labelled and packaged on site for shipment analytical laboratories.

Drilling techniques

No drilling was conducted as part of the sample collection. Previously drilled holes targeting different oil and gas producing horizons were utilised to access the clastic zones.

Figure 9: Anson Claim outlines showing wells used to delineate Clastic Zones.

Criteria used for classification

Anson has re-entered four holes (table 8, highlighted in brown) and collected samples for analytical test-work. These holes were used as the basis for indicated resources. The wells have produced free flowing brine and the samples have been analysed for elements of interest. Resources have been classified as Indicated within 2 km of a sampled clastic zone. Inferred resources are within 4 km of a sampled horizon. This has been increased from the previous 1km and 3km respectively based on the increased number of samples and the continuity grade and effective porosity of overlapping zones around sampled holes. Historic data has now also been included in Indicated resources whereas previously this was only classified as Inferred. Recent sampling conducted by Anson has verified the historic sampling so this is now considered valid for inclusion on the higher confidence classification. Other holes sampled by previous explorers are also included in Table 8.

Table 8: Assay results of the samples used in the Resource Estimation.

Sample analysis method

Samples taken by Anson from the four re-entry wells were assayed for a series of elements utilising different methodologies at different laboratories. SGS utilized EPA 6010B (ICP-AES) for analysis of cations, and a variety of standard methods for analysis of anions. WETLAB completed density analysis and anions by ion chromatography (EPA Method 300.0) for bromide, chloride, fluoride, and sulphate. WETLAB then subcontracted out the analysis for bromine (via Schoniger Combustion) to Midwest Microlab of Indianapolis, Indiana, and total metals by inductively coupled plasma – atomic emission spectrometry (ICP-AES) (EPA Method 200.7) for lithium, boron, and magnesium were subcontracted to Asset Laboratories of Las Vegas, Nevada.

The analysis of brines associated with oil and gas can be complex due to the interference of hydrocarbon organics when not properly prepared. Brines present challenges for analysis due the very high concentrations of anions such as calcium, chloride, and magnesium. The high concentrations of these elements drive the need for sample dilution in order to analyse for elements such as boron and lithium which can be anomalously high, yet significantly lower than calcium, chloride and magnesium. The dilution process inherently adds some level of uncertainty to the analysis and can create different analysis results between laboratories. Additionally, further work is required to characterize the in-situ parameters of the brine fluids so that the chemistry effects of changing temperature and pressure can be better understood.

Assaying methods from historic holes have not been documented. The historic assay results have been sourced from the 1965 publication by Mayhew and Heylman.

Estimation methodology

Grades were estimated by inverse distance squared grade interpolation. A minimum of one and maximum of three wells were used for the estimation. No top cuts were applied to the estimation. A maximum search distance of 11km was used to ensure all blocks in the model were informed with grades, porosity and brine density. A search box was used to eliminate the edge effects of using a search ellipse.

Cut-off grade

No cut-off grades have been applied to the resource reporting.

Mining and metallurgical methods

No mining of metallurgical assumptions or factors have been used in estimating the resource. The resource is reported as an in-situ, contained metal resource. Assumptions have been made regarding effective porosity. Effective porosity values of between 11.4% and 21.3% have been estimated for Clastic Zone 31 and 14% has been assumed for Clastic Zones 17,19,29 and 33 based on test-work applied to Clastic Zone 31. The Mississippian has been sampled with an effective porosity of 7.6% measured. The four wells re-entered and sampled by Anson have all recorded high pressure, free flowing, brine fluids at surface. To date test-work has not required pumping. While high permeabilities were recorded during well testing additional test-work is required to establish effective yield of the CZ31 unit.

Classification

The model has been classified by radius around sampled wells. Indicated resources have been classified within 2 km of a sampled well and inferred resourced within 4 km of a sampled well. The following figures show the resource classification for Clastic Zones 17, 19, 29, 31 and 33, see Figures 10, 11 and 12. The JORC Resource interpretation for the Mississippian Units is shown in Figure 13. The new clastic zones samples have only been classified as Inferred due to the limited drillhole data collected to date, see Figure 14.

It can be seen that Clastic Zone 31 has the highest level of resource confidence due to greater levels of sampling and the effective porosity test-work conducted on the Big Flat 2 well.

Block Model Details

The clastic zones were modelled using stratigraphic data from Massouth (2012). Each of the clastic zones, 17, 19, 29, 31, 33, 43, 45, 47 and the Mississippian were constructed in three dimensions using the top and bottom depths from the drillhole logs in the claim area. Block size was selected to maintain the stratigraphic delineation of each of the clastic units. The well logs extend beyond the claim boundaries, so the vertical positioning of the clastic units was delineated over the entire claim area. A point was placed at the top and bottom of each clastic unit for each well. These points were then used to construct a top and bottom surface for each clastic unit. Estimation was done with inverse distance squared interpolation.

JORC Code 2012 “Table 1” Report

Section 1 Sampling Techniques and Data

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

Criteria JORC Code Explanation Commentary
Sampling techniques Nature and quality of sampling (e.g. cut channels, random chips, or specific
specialized 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 mineralization that are Material to the
Public Report.
In cases where ‘industry standard’ work has been done this would be
relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m
samples from which 3 kg was pulverized 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 mineralization types (e.g. submarine nodules) may warrant
disclosure of detailed information.
• Historical oil wells (Gold Bar Unit #2, Cane Creek
#32-1-25-20, Skyline Unit 1, and Long Canyon Unit 2) were utilized to access brine
bearing horizons for sampling at the Paradox Project. Geophysical logging was
completed to determine geologic relationships and guide casing perforation. Once
perforated, a downhole packer system was utilized to isolate individual clastic
zones and Mississippian Units (production intervals) for sampling. Perforation and
packer isolated sampling moved from bottom to top to allow for the use of a single
element packer.
• Brine fluid samples were discharged from each sample interval to large 1,000 L
plastic totes. Samples were drawn from these totes to provide representative
samples of the complete volume sampled at each production interval.
• The brine samples were collected in clean plastic bottles. Each bottle was marked
with the location and sample interval.
Drilling Techniques Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air
blast, auger, Bangka, sonic, etc.) and details (e.g. 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.).
• Standard mud rotary drilling will be utilized to re-enter historical oil wells. The wells
had been previously plugged and abandoned in some cases, requiring drill out of
cement abandonment plugs. All drilling fluids were flushed from the well casing
prior to perforation and sampling activities.
• Historical drilling techniques into the Mississippian are not known but the wells
were deep exploratory wells accessing oil and gas.
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.
• No new drill holes were completed. Therefore, no drill chips, cuttings, or core was
available for review.
• Drill core from the wells located on the purchased ground had previously been
collected and laboratory tested for specific yield etc.
• Drilling procedures for well re-entry will only produce cuttings from cement plugs.
• Drilling of the new units resulted in cuttings being collected at the same time as
the brine sampling was carried out.

Sub-sampling Techniques
and 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
maximize 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.
• Bulk brine samples will be collected for potential further analysis.
• Core samples were collected in the Long Canyon No 1, Big Flat Unit 1, Big Flat
Unit 2 and Big Flat Unit 3 wells from the Mississippian Units.
• Cuttings have been saved for most of the wells drilled in the area.
For all sample types, the nature, quality and appropriateness of the sample
preparation technique.
Quality control procedures adopted for all sub-sampling stages to
maximize 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.
Historic Wells

• Duplicate samples kept Storage samples will also be collected and securely stored.
• Bulk samples will also be collected for future use.
• Sample sizes will be appropriate for the program being completed.
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 (e.g. standards, blanks,
duplicates, external laboratory checks) and whether acceptable levels of
accuracy (i.e. lack of bias) and precision have been established.
• Analysis of brine fluids were completed at several laboratories including SGS
(Applied Technology and Innovative Centre), Empact Laboratories and Enviro-Chem
Analytical, Inc. All labs followed a standard QA/QC program that included
duplicates, standards, and blind control samples. Future sampling will also be
carried out at these laboratories.
• The quality control and analytical procedures used
by the three analytical
laboratories are considered to be of high quality.
• The assaying technique for the Big Flat No 2 well in the Mississippian is not known.
The sample was assayed by the Ethyl Corporation.
• Duplicate and standard analyses are considered to be of acceptable quality.
Limited downhole geophysical tools were utilized for orientation within the
cased oil wells prior to perforation. These are believed to be calibrated
periodically to provide consistent results.

Criteria JORC Code Explanation Commentary
Mineral Tenement and
Land Tenure Status
Type, reference name/number, location and ownership including agreements
or material issues with third parties such as joint ventures, partnerships,
overriding royalties, native title interests, historical sites, wilderness or
national park and environmental settings.
The security of the tenure held at the time of reporting along with any known
impediments to obtaining a license to operate in the area.
• The Paradox Basin Brine Project is located in southeastern Utah, USA, and
encompasses a land position of 23,135 hectares.
• The land position is constructed from 2,642 Federal placer mineral claims, and
three mineral leases from the State of Utah.
• A1 Lithium has 50% ownership of 87 of the 2,434 mineral claims through an
earn-in joint venture with Voyageur Mineral Ltd. All other claims and leases are
held 100% by Anson’s U.S. based subsidiary, A1 Lithium Inc.
• The claims/leases are in good standing, with payment current to the relevant
governmental agencies.
Exploration Done by
Other Parties
Acknowledgment and appraisal of exploration by other parties. • Historical exploration for brines within the Paradox Basin includes only limited
work in the 1960s. No brine resource estimates had been completed in the
area, nor has there been any historical economic production of bromine or
lithium from these fluids.
• The historical data generated through oil and gas development in the Paradox
Formation has supplied some information on brine chemistry.
Geology Deposit type, geological setting and style of mineralization.
The geology of the Paradox Formation indicates a restricted marine basin, marked
by 29 evaporite sequences. Brines that host bromine and lithium mineralization
occur within the saline facies of the Paradox Formation and are generally hosted
in the more permeable dolomite sediments.

Controls on the spatial distribution of certain salts (boron, bromine, lithium,
magnesium, etc.) within the clastic aquifers of the Paradox Basin is poorly
understood but believed to be in part dictated by the geochemistry of the
surrounding depositional cycles, with each likely associated with a unique
geochemical signature.
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:
-easting and northing of the drill hole collar
-elevation or RL (Reduced Level – elevation above sea level in meters) of
the drill hole collar
-dip and azimuth of the hole
-down hole length and interception depth
-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.

Four existing oil wells were re-entered and worked at the Paradox Project to
collect brine samples. Although these wells may be directional, all wells are
vertical (dip -90, azimuth 0 degrees) through the stratigraphy of interest.

Detailed historical files on these oil wells were reviewed to plan the re-entry,
workover and sampling activities.

Following geophysical logging to confirm orientation within the cased well,
potential production intervals were perforated, isolated and sampled.

The target horizons in the Paradox Formation are approximately 1,800 meters
below ground surface.

Data on hundreds of historic wells is contained with a database published by
the Utah Geological Survey. Open File Report 600 ‘WELL DATABASE AND MAPS
OF SALT CYCLES AND POTASH ZONES OF THE PARADOX BASIN, UTAH’,
published in 2012.

Data Aggregation
Methods
In reporting Exploration Results, weighting averaging techniques, maximum
and/or minimum grade
Brine samples taken in holes were averaged (arithmetic average) without 14
Criteria JORC Code explanation Commentary truncations (e.g. 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.

No weighting or cut-off grades have been applied.
Relationship Between
Mineralization Widths
and Intercept Lengths
These relationships are particularly
important in the reporting of
Exploration Results.
If the geometry of the mineralization 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 (e.g. ‘down hole length, true width not
known’).

The sediments hosting the brine aquifer are interpreted to be essentially
perpendicular to the vertical oil wells. Therefore, all reported thicknesses are
believed to be accurate.

Brines are collected and sampled over the entire perforated width of the zone.

The Mississippian Units are assumed to be porous and permeable over its entire
vertical width based on drilling records and core samples.
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.

A diagram is presented in the text showing the location of the properties and re-
entered oil wells.
Balanced Reporting Where comprehensive reporting of all Exploration Results is not
practicable, representative reporting of both low and high grades and/or
widths should be practiced to avoid misleading reporting of Exploration
Results.

All data generated by A1 Lithium through re-entry, workover, and sampling of
historical oil wells has been previously presented. No newly generated data has
been withheld or summarized.
Other Substantive
Exploration Data
Other exploration data, if meaningful and material, should be reported
including (but not limited to): geological observations; geophysical
survey results; geochemical survey results; bulk samples – size and
method of treatment; metallurgical test
results; bulk density,
groundwater,
geotechnical
and
rock
characteristics;
potential
deleterious or contaminating substances.

All available current exploration data has been presented.
Further Work The nature and scale of planned further work (e.g. tests for lateral
extensions or depth extensions or large-scale step-out drilling).
Diagrams clearly highlighting the areas of possible extensions, including
the main geological interpretations and future drilling areas, provided
this information is not commercially sensitive.

The well re-entries and sampling planned will cover the Paradox Formation and
Leadville Limestone.

Future well re-entries will focus on wells surrounding the proposed re-entry
locations to upgrade future JORC resources.

Section 3 Reporting of Mineral Resource Estimates

Criteria JORC Code explanation Commentary
Database integrity
Measures taken to ensure that data has not been corrupted by, for example, transcription or
keying errors, between its initial collection and its use for Mineral Resource estimation
purposes.

Data validation procedures used

Data has been verified by company personnel.

Historic data used in the estimation has been sourced from Utah Geological Survey
publications.
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 competent person has not visited site

Other CP’s and consultants who have provided data and information for the
estimate were on-site to supervise the wellre-entry, sampling and assaying procedures.
Geological
interpretation

Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral
deposit.

Nature of the data used and of any assumptions made.

The effect, if any, of alternative interpretations on Mineral Resource estimation.

The use of geology in guiding and controlling Mineral Resource estimation.

The factors affecting continuity both of grade and geology.

The geological interpretation, location and depth of the brine bearing units is very
well known and documented through the drilling of hundreds of oil and gas wells
over the past century.

The Paradox Basin is a large, deep basin containing thousands of metres of
sediments containing various levels of oil, gas and brine. The sedimentary layers
have been correlated over most, if not all, of the basin. This enables an accurate
assessment of the position of the brine unit Clastic Zones 17, 19, 29, 31, 33 and
Mississippian.
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 brine bearing units are encountered at depth over the entire Anson claim area.

Available data indicates that the units contains brine throughout its extent within the
Anson claims.

The Anson claims cover an area of about 10km x 10km and this entire area has
been covered by the estimation.

Within the claim area the brine unit (Clastic Zones 17, 19, 29, 31,33 and
Mississippian) are found at vertical depths up to 1500m to 2500m below surface.

The producing unit averages 6m in thickness.
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.

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 assumptions made regarding recovery of by-products.
Estimation of deleterious elements or other non-grade variables
of economic significance (eg sulphur for acid mine drainage characterisation).

The brine grades were modelled using inverse distance squared grade interpolation.

A single composite for the producing unit in each well was used to estimate grades.

Lithium, Bromine, Iodine, Boron, porosity and brine density were all modelled where
there was data present.

A search box was used to eliminate the edge effect of using a search ellipse. The
search box was 8000m x 8000m to ensure all the project area was covered.

Minimum samples used in the estimation was 1 and the maximum was 3.

A total of 202 wells were used to determine the depth and thickness of the brine
producing unit. Lithium grades are available for a total of 8 wells, some of which are
outside the Anson claims; their grades were interpolated into the Anson claims.

Bromine data was from 7 wells and Iodine from 4. There were 20 density and 20
porositymeasurements.

In the case of block model interpolation, the block size in relation to the average sample
spacing and the search employed.

Any assumptions behind modelling of selective mining units.

Any assumptions about correlation between variables.

Description of how the geological interpretation was used to control the resource estimates.

The parent block size used was 500m x 500m with sub blocks to 20m x 20m to
enable adequate definition of the brine unit.

There is correlation between variables based on the total dissolved solid (TDS)
content.

of the brine.
Criteria JORC Code explanation Commentary

Discussion of basis for using or not using grade cutting or capping.

The process of validation, the checking process used, the comparison of model data to drill
hole data, and use of reconciliation data if available.

Cutting of assays was not appropriate as grade is based on the TDS levels. Mapping
of brine saturation levels indicates that the Paradox Basin does contain higher levels
of saturation at its deeper centre.

Effective porosity was used
Clastic Zone–14%
Mississippian–7.6%

The brine is contained within the producing units (Clastic Zones 17, 19, 29, 31, 33,
43, 45, 45, 47 and Mississippian). The contained brine is estimated by multiplying
the volume by the effective porosity and then by the brine density.
Moisture
Whether the tonnages are estimated on a dry basis or with natural moisture, and the
method of determination of the moisture content.

Lithium brine is a liquid resource, moisture content is not relevant.

Density of the brine is approximately 1.2t/m³. Actual measurements of sampled
material been used in the estimation.

Tonnages of product equivalent eg lithium carbonate are reported as dry tonnes.
Cut-off parameters
The basis of the adopted cut-off grade(s) or quality parameters applied.

No cut-off grades were applied.

Based on field observations, the brine density and chemistry is relatively consistent.
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. Where this is the case, this should be reported with an explanation
of the basis of the mining assumptions made.

Testwork on re-entering historic wells has indicated that brine can be recovered from
the producing unit.

To date four drill wells have been re-entered successfully with pumping tests
producing mineral bearing brine.

Two holes, Long Canyon Unit 2 and Cane Creek 32-1 were deepened to provide a
brine sample from the Mississippian zone.
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. Where this is the case, this should be reported with an
explanation of the basis of the metallurgical assumptions made.

No assumptions regarding the metallurgical or recoverability characteristics of the
brine have been assumed in the estimation.

However, lithium carbonate and lithium hydroxide has been produced from bench
top test-work from recently collected brine samples.

Criteria JORC Code explanation Commentary
Environmental
factors or
assumptions

Assumptions made regarding possible waste and process residue disposal options. It is
always necessary as part of the process of determining reasonable prospects for eventual
economic extraction to consider the potential environmental impacts of the mining and
processing operation. While at this stage the determination of potential environmental
impacts, particularly for a greenfields project, may not always be well advanced, the status
of early consideration of these potential environmental impacts should be reported. Where
these aspects have not been considered this should be reported with an explanation of the
environmental assumptions made.

The brine was produced from historic wells with no new drilling taking place except for
the Mississippian in No 2 Long Canyon Unit which was deepened to intersect this unit.

No waste products are left on site.

No environmental assumptions were used in this estimation.

Environmental reports are being carried out for future pilot plant processing.
Bulk density
Whether assumed or determined. If assumed, the basis for the assumptions. If determined,
the method used, whether wet or dry, the

frequency of the measurements, the nature, size and representativeness of the samples.

The bulk density for bulk material must have been measured by methods that adequately
account for void spaces (vugs, porosity, etc), moisture and differences between rock and
alteration zones within the deposit.

Discuss assumptions for bulk density estimates used in the evaluation process of the
different materials.

Brine density measurements were based on samples from the pump tests carried out
by Anson in 2018 and 2019.

Data was measured in commercial laboratories.

Total Porosity measurements were taken utilising a combination of neutron density
logs and sonic logs for the three re-entry holes. Effective porosity was measured using
high pressure mercury injection.

Permeability was measured during the well re-entry. Skyline returned 6,543 md (milli
darcys) and Long Canyon 1,698 md. These indicate high levels of permeability.

Additional testwork is required to enable accurate estimates of effective or drainable
porosity.
Classification
The basis for the classification of the Mineral Resources into varying confidence categories.

Whether appropriate account has been taken of all relevant factors (ie 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).

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

The Mineral Resource estimate is reported here in compliance with the 2012 Edition
of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources
and Ore Reserves’ by the Joint Ore Reserves Committee (JORC). The resource was
classified as an Indicated and Inferred Mineral Resource based on data quality,
sample spacing, and lode continuity.

The recent pump tests carried out by Anson have provided samples with a known
provenance and assaying technique.

These assays were used as the basis for the indicated resources.

Indicated Resources are within 2km of the well.

From 2 to 4km the resource is categorised as Inferred.

Outside 4km the brine mineralisation is encompassed in the Exploration Target.

The classification appropriately represents the level of confidence in the contained
mineralisation and it reflects the competent persons view of the deposit.
Audits or reviews The results of any audits or reviews of Mineral Resource estimates.
No audits or review of the Mineral Resource estimate has been conducted.

Criteria JORC Code explanation Commentary
Discussion of
relative accuracy/
confidence

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.

The geology and stratigraphy of the Paradox Basin is very well known.

The brine unit the subject of this resource estimation is known to contain super
saturated brine at pressure from the drilling of many oil and gas wells.

The resource is reported as in-situ tonnes of mineralisation.

Further testwork is required to enable recoverable volumes of brine to be estimated.
