·    The Company confirms that its projects are not subject to state participation requirements but the Company has the option to invite a state company to participate and will endeavour to develop the projects to the optimal benefit of all stakeholders

Aldo Boitano, Chief Executive Officer, of CleanTech Lithium PLC, said:

"CleanTech Lithium continues to make significant progress on the ground across all three of our projects, with drilling campaigns running simultaneously and delivering results and valuable insights to inform our path to production.

"At Llamara, while unexpected to encounter gas which required the well to be remediated before reaching the intended depth, the Board is encouraged by the findings, encountering brine at shallower depths than expected. We have already commenced drilling a well in a new location which, based on seismic data, is not expected to intersect gas.

"In the coming weeks we will be updating the market on JORC upgrades from Laguna Verde and from Francisco Basin, with the Scoping Study for Francisco Basin following shortly afterwards.

"We continue to have very positive discussions with the Government and state entities regarding the development of our projects and will provide further updates on progress in the coming weeks."

Operations Update

Laguna Verde

Re-sampling of LV02 - Assays averaging 203mg/L and up to 417mg/L Lithium recorded

LV02 was one of three drill holes completed and sampled in 2022 which contributed to the current JORC compliant resource estimate of 1.51 million tonnes of Lithium Carbonate Equivalent (LCE), as shown in Figure 1. The well was drilled to a depth of approximately 300m with the brine aquifer recorded from 55m to 290m. 

During the drilling campaign in 2022, LV02 could not be developed effectively and sampled with an electronic bailer, which is a more accurate sampling method.  This contributed to samples having a dilution factor from the fresh water used during drilling. During the 2023 exploration season the well was successfully developed, which involves purging multiple volumes of the well brine, and sampled with an electronic bailer, to collect higher quality samples.

Fig 1: Laguna Verde Resource Drill Programme Map

A total of 29 samples were recorded from the aquifer zone with the electronic bailer, as shown in Fig. 2, and submitted for analysis by independent laboratory, ALS Chile.  The average lithium grade for the 29 samples was 203mg/L, with an increasing trend with depth and highest grades of 299mg/L and 417mg/L Lithium recorded. This compares to the average grade of 191mg/L from the sampling during the 2022 programme. The use of electronic bailer samples instead of discardable bailer drilling samples will also contribute to the estimation of a Measured resource estimate for the well, versus the previous Indicated resource estimate.

Figure 2: Bailer Sampling using an Electronic Bailer

Assay Results from Wells Completed in 2023: LV04 - LV06

At LV05 drilling reached a depth of 434m with an aquifer thickness of 375m. A total of 62 samples were collected from every 6m of the aquifer with an electronic bailer and submitted for laboratory assay. The average lithium grade of the 62 samples is 202 mg/L with a range of 175 mg/l to 315 mg/L lithium. At LV06, drilling reached a depth of 405m with an aquifer thickness of 342m. A total of 53 samples were collected with an electronic bailer every 6m with assay results received. The average lithium grade of the samples is 174mg/L Lithium with a range of 147mg/L to 225mg/L lithium. 

Well LV04 was drilled on the south-east margin of the resource area and lithium grades were low, which will result in the resource area not being extended in the area of LV04 in the 2023 upgrade.

Lithium grades encountered at Laguna Verde have shown significant variation in grades at various depths. For example, at LV02 grades ranged from 90mg/L to 417mg/L across the aquifer zone. In a commercial operation, an operating well would be cased selectively with screens over the higher grade levels and blank casing over lower grade levels, to ensure feed brine utilises higher grade brine than the overall average grade of the aquifer. 

There will be a JORC resource upgrade in early Q3 which will include the results of wells completed in the 2023 drill programme, as well as the recent pump tests completed at LV05 and LV06, which were reported to the market on May 30^th 2023 and is expected to result in a significant rise in the proportion of resources in the Measured and Indicated category.

Francisco Basin Project Exploration Drill Programme

At Francisco Basin we have now completed the three wells originally planned for the 2023 resource drill programme, while a further two wells have been added to the programme which is currently underway.  The status of the wells is provided as per the table below.

2023 Drill Programme Well	Depth	Status at 04/06/2023
FB02	369	Casing completed, brine sampling to commence
FB03	320	Casing completed, brine sampling to commence
FB04	415	Casing underway
FB05	452	Completed, core samples dispatched for porosity tests, casing underway
FB06	204	Drilling underway

Wells FB05 and FB06, shown in Figure 3, were added to the programme as these were within the programme budget and have the potential to extend the resource area. FB04 is a water well completed with 8-inch casing which can be used for pump tests. FB05 and FB06 use the diamond drill method that collects core samples which will be sent to an independent laboratory in the US specialising in porosity analysis, to produce a porosity estimate that will be used in the JORC resource estimate.

Fig 3: Francisco Basin Resource Drill Programme Map

After the completion of the 2023 drill programme, brine sampling and laboratory assay work, a JORC resource upgrade at the Francisco Basin project is expected in early Q3 2023. A Scoping Study on the project is nearing completion, pending the completion of the JORC resource upgrade. New lithium pricing forecast provided by Canaccord Genuity1 will be used for the Francisco Basin Scoping Study, which will also be reflected in a revision to the economics of the Laguna Verde Scoping Study completed in January 2023.  

Llamara Project Exploration Drill Programme

The Llamara Project is a greenfield exploration project. In late April a drill rig was mobilised to the project with drilling of the maiden exploration drill hole, LL01, commencing on April 23^rd. The programme is based on utilising a diamond drilling method with a 6-inch diameter, which allows for the collection of core samples and water samples via using a packer system. This is a relatively low-cost method of drilling. Drilling of LL01 progressed rapidly with good core recovery to 292m. At 290m, drilling transitioned from dense clays to a porous sandstone, as shown in Fig 4. 

Fig.4: LL01 Core Sample Showing Clay to Sandstone Transition

In this sandstone layer, brine was recorded along with a flow of gas which was unexpected based on regional geology. Historically there have been four deep oil and gas exploration holes drilled within the basin which did not record gas. As the gas is present at a shallow depth, the pressure and flow rate were modest, however, for safety reasons, it necessitated the completion of the well which has now been remediated and sealed with concrete.

Fig.5: LL01 Drill Site

Two brine samples were collected from the sandstone layer with a relatively high salinity based on field measurement. This is a positive sign for the exploration programme as brine was expected to be encountered at significantly deeper levels. As LL01 was unable to be drilled to the target depth, a second exploration drill hole LL02 has commenced at an alternative location approximately 6km west of LL01, as shown in Fig. 6, which is closer to the historical oil and gas well Hilaricos, in which no gas was recorded in drilling logs to 980m. Following evaluation of a historical seismic survey, the gas sequence is interpreted by the Company to be associated with a deep fracture zone east of LL01.   

The discovery of the gas sequence at LL01 will be further evaluated from a resource potential perspective, however the Company´s focus at the Llamara project remains on the evaluation of the brine aquifer and its potential to host a lithium resource. A sampling programme targeting a large near surface evaporite layer, which has been sampled in other areas of the basin and returned elevated lithium values, is also planned.

Chile's National Lithium Strategy / Minister of Mining Clarifies Strategic Project Definition

In a recent interview with Mining.com, Minister of Mining, Marcela Hernando, addressed the concerns raised by the industry. In the interview, the Minister clarified the state will only be moving to majority state participation with projects considered to be 'strategic' that operate in the Salar de Atacama. This area has currently been licensed by the government to leading lithium producers SQM and Albemarle. The new strategy will see these contracts being renegotiated and revised in 2030 and 2043 respectively.

CTL's projects are outside of the Salar de Atacama meaning the Company understands that it can apply for a CEOL (Operating Contract) itself and has the option to invite a state entity to participate. CTL continues to have constructive discussions with the Government and other state participants on this, the benefits of DLE and the sustainability credentials this method offers to produce lithium. As stated by the Government, DLE technology is now a priority for all future lithium projects, and CTL is well placed to help drive the changes necessary to deliver on this.

Laguna Verde - JORC Code, 2012 Edition - Table 1 report template

Section 1 Sampling Techniques and Data

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

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.	·    Lagoon samples correspond to water brine samples from the surface lagoon, in an 800 m sampling grid, including eight (08) sampling duplicates in random positions. The samples were taken from 0.5 m depth and, for positions with above 5 m depth a bottom sample were also obtained.   ·    For every sample, two (02) liters of brine were obtained with a one-liter double valve bailer, using a new bailer for each sampling position. All materials and sampling bottles were first flushed with 100 cc of brine water before receiving the final sample. ·    Sub surface brine samples were obtained with four methods: Packer sampling, PVC Casing Suction sampling, PVC Casing Discardable Bailer sampling, and PVC Casing Electric Valve Bailer. ·    For the Packer sampling, a packer bit tool provided by the drilling company (Big Bear) was used. Once the sampling support was sealed, a purging operation took place until no drilling mud was detected After the purging operation, half an hour waiting took place to let brine enter to the drilling rods thru the slots in the packer tool before sampling with double valve bailer. ·    Successive one-liter samples with half an hour separation were taken with a steel made double valve bailer. Conductivity-based TDS was measured in every sample with a Hanna Multiparameter model HI98192. The last two samples that measure stable similar TDS values were considered as non-contaminated and identified as the Original and Reject samples. ·    Packer samples were obtained every 18 m support due the tools movement involved to take every sample. ·    PVC Casing Suction brine samples were extracted after the well casing with 3-inch PVC and silica gravel and the well development (cleaning) process. The well development includes an injection of a hypochlorite solution to break the drilling additives, enough solution actuation waiting time and then, purging of three well volumes operation to clean the cased well from drilling mud and injected fresh water. ·    The developing process was made by OSMAR drilling company using a small rig, a high-pressure compressor and 2-inch threaded PVC that can be coupled to reach any depth. The purging/cleaning operation is made from top to bottom, injecting air with a hose inside the 2-inch PVC and "suctioning" the water, emulating a Reverse Circulation system. ·    Once the well is clean and enough water is purged (at least three times the well volume) and also, is verified that the purged water is brine came from the aquifer, the PVC Casing Suction samples are taken from bottom to top, while the 2-inch PVC is extracted from the well. A 20-liter bucket is filled with brine and the brine sample is obtained from the bucket once the remaining fine sediments that could appear in the sample decant. ·      PVC casing Suction samples were taken every 6 m support due the disturbing and mixing provoked by the suction process.  Conductivity-based TDS (Multi-TDS) and Temperature °C are measured for every sample with the Hanna Multiparameter. ·      After the development process and PVC Casing Suction sampling, a stabilization period of minimum 5 days take place before this sampling to let the well match the aquifer hydro-chemical stratigraphy. ·      PVC Casing Discardable samples were obtained by JCP Ltda.  specialists in water sampling. Samples were taken from the interest depths with a double valve discardable bailer. The bailer is lowered and raised with an electric cable winch, to maintain a constant velocity and avoid bailer valves opening after taking the sample from the desire support. A new bailer was used for each well ·      Discardable Bailer samples were obtained every 6 m support to avoid disturbing the entire column during the sampling process. Conductivity-based TDS (Multi-TDS), Temperature °C and pH were measured for every sample with the Hanna Multiparameter ·      On first quarter of 2023 Electric Bailer samples were taken from wells LV05, LV06 and LV02, after it´s proper development. The samples were obtained from the interest depths with a one litter electric  bailer, that seals in the sampling support with an electric valve activated by the operator. This sampling process was made by Geodatos specialists.  ·    On all sampling procedures the materials and sampling bottles were first flushed with 100 cc of brine water before receiving the final sample ·    Packer samples are available in wells LV01, LV02 and LV03. PVC Casing Suction samples are available in wells LV01, LV04, LV05 and LV06. PVC Casing Discardable Bailer samples are available in wells LV01 and LV02. Electronic Bailer samples are available in wells LV02, LV05 and LV06.

The TEM geophysical work has been useful in defining the extensional limits of the salar at Laguna Verde". ·      Respect the Specific Yield his comments are "RBRC test work at Danial B. Stevens Associates has been well done. It is recommended obtaining specific yield data using a second method such as centrifuge, nitrogen permeation or NMR. The available RBRC data indicates an average Sy value of 5.6%. This is a significant decrease from the previously estimated value of approximately 11%. The implications of the lower RBRC value in terms of the overall resource estimate should be carefully evaluated". ·      Several recommendations were made by Mr. Hines in his report to improve the QA/QC protocols, data acquisition, assays, presentation and storage. His recommendations have been considered and included in the exploration work schedule since October 2022.

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 relationship between aquifer widths and intercept lengths are direct, except in LV03 were a dip of -60° should be applied
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.	·    Addressed in the report
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 results have been included.

The outcome of the visit was a general geological review and the lagoon water brine geochemical sampling that lead to the July 2021 JORC Technical Report ·    The January to May 2022 drilling campaign was continually supervised by the Competent Person, that led to the September 2022 updated JORC Technical Report ·    The October 2022 to May 2023 drilling campaign was constantly supervised by the Competent Person
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.	·    For the Surface Brine Resource, the interpretation is direct and there is no uncertainty. ·    For the Sub-Surface Resource, the geological interpretation was made based in the TEM study and gravimetry (SRK, 2011). The lithological interpretation was confirmed by the January - May 2023 diamond drillhole campaign. ·    Low resistivities are associated with sediments saturated in brines, but also with very fine sediments or clays. The direct relationship of the low resistivity layer with the above hypersaline lagoon raise the confidence that the low resistivities are associated with brines. ·    Drillholes confirm the geological interpretations
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.	·    For the Surface Brine Resouce the lagoon dimensions are 14,682,408 m2 of area with depths ranging from 0 m to 7.18m with an average depth of 4.05 m ·    The Sub-Surface Brine Resource is a horizontal lens closely restricted to the lagoon perimeter with an area of approximately 55 km2 and depths for more than 300 m, from approximately 4,309 m a.s.l. to the basement level.
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). ·    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. ·    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.	·      For the Surface Brine resource, the surface lake brine water volume is directly obtained by the bathymetry study detailed on Section 4.2. ·      Lithium (mg/l) samples values are in general homogeneously distributed along the lagoon with a narrow value distribution. the lagoon is a free water body where the ionic content is dynamic for every specific position, there is no point in estimate the lake lithium content via Kriging or other geostatistical method. The use of the total samples average value 245.794 mg/l was used for the Surface Brine Resource Estimation. ·      The Sub-Surface geological 3D model was built modifying the 50 m plans constructed for the September 2022 resource, considering the drillholes interceptions, the TEM geophysics continuity from all the available geophysical sections (in general < 4 Ohm-m zones). The constructed 3D model was clipped above the brine aquifer ceiling surface, formed by the first brine intercepts on the drillholes and also, below the basement surface that was constructed using the basement intercepts on drillholes LV01 and LV02 and structural geological information. This geological 3D model corresponds to the Sub-Surface Brine Ore Volume ·      Two block models were constructed for resource calculation due the different type of brine samples used for resource estimation, one above the 4,112 m a.s.l. and the other, below 4,112 ma.s.l. ·      The block model above level 4,112 m a.s.l. properties are: Block size: 200 m x 200 m x 6 m. Block Model Origin: 547,000 East, 7,026,000 North, Level 4,328 m a.s.l. N° Columns: 72 N° Rows: 40 N° Levels: 36 Rotation: 20° Clockwise ·      The block model below level 4,112 m a.s.l. properties are: Block size: 200 m x 200 m x 6 m. Block Model Origin: 547,000 East, 7,026,000 North, Level 4,112 m a.s.l. N° Columns: 72 N° Rows: 40 N° Levels: 35 Rotation: 20° Clockwise ·      On both block models the individual block variables are: Rock Type: 0=No Ore, 1= Brine Ore Density Percent Economic Material Li (Lithium) Mg (Magnesium) K (Potash) B (Boron) SO4 Ca (Calcium) Category: 1=Measured, 2=Indicated and 3=Inferred Porosity Elevation ·      The traditional Inverse to the Square Distance method to estimate the block variables was used. To accomplish this, the samples from the Sub-Surface Assay Resource Database were manually assigned to their correspondent block levels on both block models. Once assigned, the block variable values were calculated by levels with the correspondent assigned samples and their horizontal distances from the individual block to estimate. All calculations were performed in EXCEL files. ·      The Sub-Surface Assay Resource Database was constructed according the following considerations: ·      PVC casing Bailer samples from drillholes LV01 and LV02 were used from level 4,309 m a.s.l., down to 4,112 m a.s.l. ·      Samples evidently contaminated with drilling water were extracted from LV02 preliminary PVC Casing Bailer samples and the gaps were replaced with the correspondent LV02 Packer sample. ·      Packer samples from LV01 and LV03 drillholes plus the deepest seven (07) PVC Casing Bailer samples from well LV02 and, a final auxiliary average composite sample from the seven before mentioned samples were used to calculate resources below level 4,112 m a.s.l. to the basement level at 3,955 m a.s.l. ·      The validation process was mainly visual check in plans along block model levels and, on the estimation EXCEL files ·      For both block models, the blocks inside the Sub-Surface Brine Ore Volume have variable Rock Type = 1 (Brine Ore). Only blocks with Rock Type = 1 were reported as resource
Moisture	·    Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content.	·    Not applicable for brine resources
Cut-off parameters	·    The basis of the adopted cut-off grade(s) or quality parameters applied.	·    A cut-off of 150 mg/l Li was used to report resources in the Above 4,112 m block model, mainly to discount blocks estimated with low grade samples located in the fresh water / brine transition zone
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.	·    Mining will be undertaken by pumping brine from production wells and re-injection ·    Pump tests were performed in wells LV05 and LV06 ·      A 50 hp submergible electric pump, piping with flowmeters were used for the pump tests. The tests consist in 6-hour variable pump test to verify the aquifer capabilities and a constant 48-hour pump test ·      In LV05 the pump was installed at 156 m and in LV06, at 150 m
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.	·      The metallurgical capacity of lithium recovery in the process has been estimated at 85.2% to obtain lithium carbonate in battery grade. ·      The process of obtaining lithium carbonate considers the following stages: o  The Lithium is obtained using selective adsorption of lithium-ion from Laguna Verde brine through the Direct Lithium Extraction (DLE) process. This stage has 90.4% recovery of Lithium. o  The spent solution (without Lithium) will be reinjected into the Laguna Verde salt flat. o  The DLE process allows impurity removal waste to be minimal. o  The diluted lithium solution recovered from the DLE process is concentrated utilizing water removal in reverse osmosis. The removed water is recovered and returned to the process to minimize the water consumption required.  o  Ion exchange stages remove minor impurities such as magnesium, calcium, and boron to obtain a clean lithium solution. o  Lithium carbonate is obtained with a saturated soda ash solution to precipitate it in the carbonation stage. Lithium recovery from this stage is 87.2%. o  The lithium carbonate obtained is washed with ultra-pure water to get it in battery grade with the minimum of impurities. o  From the carbonation process, a remaining solution (mother liquor) is obtained, which is treated to concentration utilizing evaporators to recirculate in the carbonation process and ensure the greatest possible recovery of Lithium. The removed water is recovered and reintegrated into the process. o  The water recovery in the process is 74% which reduces the water consumption required. ·      The Direct Extraction process has been tested by Beyond Lthium LLC at its facilities in the city of Salta, Argentina. The stages of removal of impurities and carbonation have been tested, obtaining a representative sample. The sample was analyzed in Germany by the laboratory Dorfner Anzaplan showing 99.9% Li2CO3 and reduced contaminants. ·      The process has been modeled Ad infinitum using the SysCAD simulation platform and the AQSOL thermodynamic property package. With the model, simulations of the process were made to obtain  the appropriate mass balances with which the process stages and the recovery of Lithium are described for obtaining 20,000 tons of Li2CO3 per year. ·      Metallurgical testing and process is described and detailed in the CleanTech Lithium Scoping Study-Laguna Verde Project (December 2022)
Environmen-tal 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 main environmental impacts expected is the main plant installations, estimated to be located at 8 km to the south west of the lagoon edge. In the near lagoon area, the impact is the surface disturbance associated with production wells and brine mixing ponds. These impacts are not expected to prevent project development
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.	·    Undisturbed diamond drillhole core samples with 3 to 5-inch length in both PQ and HQ diameter were obtained every 10 m from all drillholes for porosity testing.  Samples were prepared and sent to Daniel B. Stephens & Associated, Inc. laboratory (DBS&A) in New Mexico, USA. Samples underwent Relative Brine Release Capacity laboratory tests, which predict the volume of solution that can be readily extracted from an unstressed geological sample.  This method by itself is insufficient for calculating an effective porosity (specific yield) value for resource estimation as the laboratory test is performed on an unstressed core sample and doesn´t account for the host lithology geotechnical condition. To attain a more realistic specific yield value, the rock quality designator ("RQD") logged during the drilling was used with a regression analysis. This provided specific yield values that are consistent with the basin lithology.
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.	·    For the Surface Brine Resource, the data is considered sufficient to assign a Measured Resource classification ·      For the Sub-Surface Resources classification, the considered criteria were based on the recommended sampling grid distances of the complementary guide to CH 20235 code to report resources and reserves in brine deposits from the Comision Calificadora en Competencias en Recursos y Reservas Mineras, Chile. ·      Besides that, the Sub-Surface Resources categorization is dependent of the brine samples availability and their quality in terms of confidence. Considering the above, the Sub-Surface resources categorization conditions are: ·      For the Above 4,112 m a.s.l. block model. Blocks estimated at 1,250 m around LV01 PVC Casing Bailer samples were considered as MEASURED Blocks estimated between 1,250 m to 3,000 m around LV01 PVC Casing Bailer samples were considered as INDICATED Blocks estimated at 3,000 m around the LV02 PVC Bailer samples were considered as INDICATED The rest of the blocks that don't match the above conditions were considered as INFERRED ·      For the Below 4,112 m a.s.l. block model. Blocks estimated at 3,000 m around LV01 and LV03 Packer samples were considered as INDICATED Blocks estimated at 3,000 m around the available LV02 PVC Bailer samples (discounting the AVERAGE auxiliary sample) were considered as INDICATED. The rest of the blocks that don't match the above conditions were considered as INFERRED ·    The result reflects the view of the Competent Person
Audits or reviews	·    The results of any audits or reviews of Mineral Resource estimats.	·      The July 2021 JORC technical report were reviewed by Michael Rosko, MS PG SME Registered Member #4064687 from MONTGOMERY & ASSOCIATES CONSULTORES LIMITADA ·      In the report he concludes that "The bulk of the information for the Laguna Verde exploration work and resulting initial lithium resource estimate was summarized Feddersen (2021). Overall, the CP agrees that industry-standard methods were used, and that the initial lithium resource estimate is reasonable based on the information available". ·      The September 2022 JORC Report LAGUNA VERDE UPDATED RESOURCE ESTIMATION REPORT, data acquisition and QA/QC protocols were audited on October, 2022 by Don Hains, P. Geo. from Hains Engineering Company Limited (D. Hains October 2022 QA/QC Procedures, Review, Site Visit Report). ·      In the report he concludes that "The overall QA/QC procedures employed by CleanTech are well documented and the exploration data collected and analysed in a comprehensive manner. There are no significant short comings in the overall programme. ·      Respect the exploration program his comments are "The overall exploration program has been well designed and well executed. Field work appears to have been well managed, with excellent data collection. The drill pads have been restored to a very high standard. The TEM geophysical work has been useful in defining the extensional limits of the salar at Laguna Verde". ·      Respect the Specific Yield his comments are "RBRC test work at Danial B. Stevens Associates has been well done. It is recommended obtaining specific yield data using a second method such as centrifuge, nitrogen permeation or NMR. The available RBRC data indicates an average Sy value of 5.6%. This is a significant decrease from the previously estimated value of approximately 11%. The implications of the lower RBRC value in terms of the overall resource estimate should be carefully evaluated". ·      Several recommendations were made by Mr. Hines in his report to improve the QA/QC protocols, data acquisition, assays, presentation and storage. His recommendations have been considered and included in the exploration work schedule since October 2022.
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 estimated tonnage represents the in-situ brine with no recovery factor applied. It will not be possible to extract all of the contained brine by pumping from production wells. The amount which can be extracted depends on many factors including the permeability of the sediments, the drainable porosity, and the recharge dynamics of the aquifers. ·    No production data are available for comparison

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.	·      After the FB01 well casing with 8-inch PVC and silica gravel, a development process took place. The well development includes an injection of a hypochlorite solution to break the drilling additives, enough solution actuation waiting time and then, purging of minimum three well volumes operation to clean the cased well from drilling mud and injected fresh water.   ·      The developing process was made using a small rig, a high-pressure compressor and 2-inch threaded PVC that can be coupled to reach any depth. The purging/cleaning operation is made from top to bottom, injecting air with a hose inside the 2-inch PVC and "suctioning" the water, emulating a Reverse Circulation (Air-Lift) system. ·      Once the well is verified, clan assuring that the purged water is brine coming from the aquifer, the PVC Casing Suction (Air-Lift) samples were taken from bottom to top, while the 2-inch PVC is extracted from the well. A 20-liter bucket is filled with brine and the brine sample is obtained from the bucket once the remaining fine sediments that could appear in the sample decant. ·      One-litre Samples every 3 m were taken and, every 6 m sent to laboratory to preserve a second sample set for auditory purposes.   ·      Conductivity-based TDS and T°C were measured in every sample with a Hanna Multiparameter.

Samples were taken from the interest depths with a double valve discardable bailer. The bailer is lowered and raised with an electric cable winch, to maintain a constant velocity and avoid bailer valves opening after taking the sample from the desire support. ·      PVC Casing Bailer samples were obtained every 6 m support to avoid disturbing the entire column during the sampling process. Conductivity-based TDS and Temperature °C were measured for every sample with a Hanna multiparameter.

Core (or costean, channel, etc) photography. ·    The total length and percentage of the relevant intersections logged.	·    Continue geological logging took place during drilling ·    For all 2022 brine samples conductivity-based TDS and Temperature °C parameters were measured during the sampling ·    From 2023, for all brine samples conductivity-based TDS, pH and Temperature °C parameters were measured during the sampling
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.	·      During the brine samples batch preparation process, Standard (internal standard composed by known stable brine), Duplicates and Blank samples (distilled water) were randomly included in the batch in the rate of one every twenty original samples. ·      After check samples insertion, all samples were re-numbered before submitted to laboratory.

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.	·    Not applicable for Exploration results ·    The assay data was verified by the Competent Person against the assay certificate
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.	·    From January 25 to January 27, 2023. Locate LL01 drillhole position, access and logistics ·    From April 05 to April 07, 2023. Confirm LL01 location with Big Bear supervisor. Assure general logistics ·    From April 20 to April 25, 2023. LL01 Drilling start-up supervision. Roko personnel brine sampling, geological and geotechnical logging procedures training ·    From May 11 to May 16, 2023. LL01 brine samples batch preparation supervision. Natural gas surge standby check and investors visit ·    From May 24 to May 25, 2023 LL01 closure supervision. LL02 drillhole positioning
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.	·    Not applicable for Exploration results
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.	·    Not applicable for Exploration results
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). ·    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. ·    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.	·      Not applicable for Exploration results
Moisture	·    Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content.	·    Not applicable for brine deposits
Cut-off parameters	·    The basis of the adopted cut-off grade(s) or quality parameters applied.	·    Not applicable for Exploration results
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.	·    Not applicable for Exploration results
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.	·    Not applicable for Exploration results
Environmen-tal 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 main environmental impacts expected is the main plant installations and the surface disturbance associated with production wells and brine mixing ponds. These impacts are not expected to prevent project development ·    No official protected areas are located on or near the exploration mining concessions area
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.	·    Not applicable for Exploration results
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.	·    Not applicable for Exploration results
Audits or reviews	·    The results of any audits or reviews of Mineral Resource estimats.	·    Not audits or reviews has been performed in Llamara
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.	·    Not applicable for Exploration results
