Libra Lithium Corp. ("Libra" or the "Company") is pleased to announce that it has entered into an earn-in agreement (the "EIA") with a wholly-owned Canadian subsidiary of KoBold Metals Company ("KoBold") to jointly explore the Company's Flanders South, Flanders North and Soules Bay-Caron ("SBC") lithium projects in Ontario, Canada (collectively, the "Earn-In Properties"). Pursuant to the EIA, KoBold will have the option to earn a 75% interest in the Earn-In Properties by incurring up to CAD$33M in exploration expenditures over six years.
KoBold Metals Company is a US-based exploration and mining company that combines expertise in geosciences with artificial intelligence, machine learning, and data science to improve and accelerate the exploration process in search for the critical minerals necessary for the global energy transition.
Libra further announces that the Company and PowerStone Metals Corp. (CSE: PS) ("PowerStone" or "ShellCo") have entered into a non-binding letter of intent dated December 2, 2024 (the "LOI") in respect of a proposed business combination (the "RTO") that would result in the reverse takeover of ShellCo by Libra. The completion of the RTO will be subject to, among other things, the common shares ("Resulting Issuer Shares") of the resulting entity (the "Resulting Issuer") being listed on the Canada Securities Exchange (the "CSE") and the Resulting Issuer fulfilling all of the applicable regulatory and listing requirements. Following the completion of the RTO, the Company is expected to become a wholly-owned subsidiary of ShellCo or otherwise combine its corporate existence with that of ShellCo to form the Resulting Issuer, which will hold all the assets and projects and continue the business of Libra.
"Our team pulled through, coming out on top from what has been a challenging lithium market over the past two years. In Fall 2023 we made our first spodumene discovery, sampling up to 2.86% Li2O within a 35m-wide pegmatite at Flanders South. Fast forward to Summer 2024, and we had discovered a new pegmatite field in the span of less than two weeks at SBC, with 18 spodumene outcrops, pegmatites up to 30m wide, samples up to 6.64% Li2O, and spodumene crystals up to 0.4m long. With limited capital, we were able to build a company with a large portfolio of lithium assets and discover lithium mineralization on three grassroots projects in under a year. We have proven our ability to systematically screen through ground and be cost-efficient, and with the market nearing a bottom, we see tremendous opportunity to be counter-cyclical. The KoBold earn-in agreement and contemplated go-public transaction with PowerStone will create a well-financed, publicly traded entity, backed by an astute shareholder base of long-term believers in the green energy transition" said Koby Kushner, CEO of Libra.
"We are excited to enter into this earn-in agreement with Libra and are looking forward to exploring the Flanders South, Flanders North, and SBC projects. The three projects are compelling, and we are eager to follow up on the encouraging data that Libra has collected to date. Furthermore, we believe that combining Libra's capable team with KoBold's experienced explorationists and exploration technology will set us up for success. We look forward to working with Libra" said Daniel Enderton, Chief Strategy Officer at KoBold Metals.
KoBold Earn-In Agreement
Libra has executed an EIA with KoBold, dated November 13, 2024, to explore the Earn-In Properties. Pursuant to the EIA KoBold has the option to earn a 75% interest in each of the Earn-In Properties by incurring up to CAD$33,000,000 in cumulative exploration expenditures across the Earn-In Properties over six years.
During the earn-in period, KoBold shall be responsible for expenses and maintenance of the claims subject to the terms of the EIA. Further, KoBold and Libra shall form a technical committee, with two members from each party, to regularly review progress and findings of exploration programs and determine next steps, with KoBold reserving final discretion over the exploration programs.
Payment and Expenditure Schedule
To meet the 75% earn-in thresholds for the Earn-In Properties, KoBold must complete the following:
- Initial Cash Payment to Libra (completed) - CAD$445,000 within 14 days of the effective date of the EIA as reimbursement of exploration expenditures for work completed before the EIA was finalized;
- Year 1 Anniversary - completion of cumulative exploration expenditures of CAD$750,000, which is a firm commitment and may be allocated across any of the Earn-In Properties;
- Year 3 Anniversary - completion of cumulative exploration expenditures of up to CAD$11,000,000 to earn a 51% interest on a project-by-project basis ("Stage 1"); and
- Year 6 Anniversary - completion of cumulative exploration expenditures of up to CAD$33,000,000 to earn a 75% interest on a project-by-project basis ("Stage 2").
The Stage 1 and Stage 2 earn-in thresholds vary by project, as shown in the table below:
Furthermore, KoBold has retained Libra as an exploration contractor for a period ending on the earlier of two years from the effective date of the EIA, or the date on which the EIA is terminated with respect to the SBC project. In exchange for exploration services, KoBold will pay Libra a monthly cash fee of CAD$35,000.
KoBold shall also pay to Libra the following milestone payments with respect to each of the Flanders South and Flanders North projects:
| Milestone | Milestone Payment (CAD$) |
| Inferred Resource of at least 100,000 tons of lithium oxide | $250,000 |
| Pre-Feasibility Study | $500,000 |
| Feasibility Study | $750,000 |
| First Ore Production | $1,000,000 |
Formation of Joint Venture Company
Upon KoBold achieving a Stage 1 cumulative earn-in threshold, the parties shall form a joint venture for the applicable project pursuant to which KoBold shall initially own 51% and Libra 49% (the "Kobra JV"). Upon KoBold achieving the Stage 2 cumulative earn-in threshold, KoBold's ownership interest in the Kobra JV shall increase to 75%. After the earn-in period, each party will be responsible for funding its pro-rata share of project costs or will be diluted; a party that gets diluted below 10% shall have its interest converted to a 1% net smelter return (NSR) royalty. The Kobra JV shall be governed by a board of directors ("Board"), initially composed of two members appointed by KoBold and two members appointed by Libra. The Board shall appoint a manager of the daily affairs of Kobra JV, with KoBold as the initial manager.

Where Does Tesla Get its Lithium?
In a mid-2023 Tesla earnings call, Musk seemed relieved to see prices for the battery metal had declined. “Lithium prices went absolutely insane there for a while,” he said. Lower battery prices will bring EVs closer to cost parity with internal combustion engines vehicles, leading to wider adoption and increased demand.
During the 2024 US presidential election, Musk threw his support behind Republican candidate and former president Donald Trump, who has been historically critical on electric vehicles and subsidies. Following Trump's election win on November 5, AP News reported that these stances could support Tesla as they would be more likely to harm smaller competitors who were less established than the EV giant. Tesla's share price shot upwards in response to the election outcome.
In the spring of 2024, Musk invited Argentine President Javier Milei to the Tesla factory in Austin, Texas, where the two reportedly discussed the investment opportunities in Argentina's lithium sector. As a prominent member of the prolific Lithium Triangle, the South American nation is the fourth leading lithium producer by country.
Australia's hard-rock deposits and Chile's brines are also top sources for the world's lithium supply. But lithium refining is dominated by China, which accounted for 72 percent of global lithium processing capacity in 2022.
With the limelight on Musk and Tesla, investors should know where the electric car company sources its lithium.
Read on to learn more about where Tesla gets its lithium, how much lithium is in a Tesla battery and what the EV maker is doing to better secure its lithium supply chain.
In this article
Which lithium companies supply Tesla?
Tesla has deals with multiple lithium suppliers, some that are already producers and some that are juniors developing lithium projects.
At the end of 2021, Tesla inked a three-year lithium supply deal with top lithium producer Ganfeng Lithium (OTC Pink:GNENF,SZSE:002460), and the Chinese company began providing products to Tesla starting in 2022. Major miner Arcadium Lithium (NYSE:ALTM,ASX:LTM), which is set to be acquired by Rio Tinto (ASX:RIO,NYSE:RIO,LSE:RIO), also has supply contracts in place with the EV maker.
China’s Sichuan Yahua Industrial Group (SZSE:002497) agreed to supply battery-grade lithium hydroxide to Tesla through 2030. Under a new, separate agreement finalized in June 2024, Yahua is set to supply Tesla with an unspecified amount of lithium carbonate between 2025 and 2027, with the option to extend the contract by another year.
Liontown Resources (ASX:LTR,OTC Pink:LINRF) is set to supply Tesla with lithium spodumene concentrate from its AU$473 million Kathleen Valley project. The deal is for an initial five year period set to begin this year, and production began in July 2024.
In January 2023, Tesla amended its agreement with Piedmont Lithium (ASX:PLL,NASDAQ:PLL), which now supplies the US automaker with spodumene concentrate from its North American Lithium operation, a joint venture with Sayona Mining (ASX:SYA,OTCQB:SYAXF). The deal is in place through the end of 2025.
Even though Tesla has secured lithium from all these companies, the EV supply chain is a bit more complex than just buying lithium directly from miners. Tesla also works with battery makers, such as Panasonic (OTC Pink:PCRFF,TSE:6752) and CATL (SZSE:300750), which themselves work with other chemical companies that secure their own lithium deals.
What are Tesla batteries made of?
Tesla vehicles use several different battery cathodes, including nickel-cobalt-aluminum (NCA) cathodes and lithium-iron-phosphate (LFP) cathodes.
Tesla is known for using NCA cathodes developed by Japanese company Panasonic. This type of cathode has higher energy density and is a low-cobalt option, but has been less adopted by the industry compared to the widely used nickel-cobalt-manganese (NCM) cathodes. Aside from that, South Korea's LG Energy Solutions (KRX:373220) supplies Tesla with batteries using nickel-cobalt-manganese-aluminum (NCMA) cathodes.
As mentioned, it wasn’t just lithium that saw prices climb in 2021 — cobalt doubled in price that same year, and although it has declined since then, the battery metal remains essential for many EV batteries. Most cobalt mining takes place in the Democratic Republic of Congo, which is often associated with child labor and human rights abuses, fueling concerns over long-term supply.
That said, not all Tesla’s batteries contain cobalt. In 2021, Tesla said that for its standard-range vehicles it would be changing to lithium-iron-phosphate (LFP) cathodes, which are cobalt- and nickel-free. At the time, the company was already making vehicles with LFP chemistry at its factory in Shanghai, which supplies markets in China, the Asia-Pacific region and Europe.
In April 2023, Tesla announced that it planned to use this type of cathode chemistry for its short-range heavy electric trucks, which it calls "semi light." The company is also looking to use LFP batteries in its mid-sized vehicles.
At the top of 2024, Tesla made moves to produce LFP batteries at its Sparks, Nevada, battery facility in reaction to the Biden Administration's new regulations on battery materials sourcing, especially on those sourced from China. Reuters reports Tesla battery supplier CATL will sell idle equipment to the car maker for use at the plant, which will have an initial capacity of about 10 gigawatt hours.
What company makes Tesla’s batteries?
Tesla works with multiple battery suppliers, including Panasonic, its longtime partner, as well as LG Energy Solutions, the second largest battery supplier in the world. They supply the EV maker with cells containing nickel and cobalt.
China's CATL has been supplying LFP batteries to Tesla for cars made at its Shanghai plant since 2020. It’s also been reported that BYD Company (OTC Pink:BYDDF,SZSE:002594) is supplying Tesla with the Blade battery — a less bulky LFP battery — which the car manufacturer has used in some of its models in Europe.
Additionally, BYD is set to work with Tesla on its battery energy storage systems (BESS) in China, with a plan to supply 20 percent of Tesla's anticipated BESS manufacturing capacity, with CATL expected to cover 80 percent. The factory, which began production at the close of 2024, uses the companies' LFP batteries.
How much lithium is in a Tesla battery?
How much lithium do Tesla batteries actually contain? That question is tricky because many factors are at play. Typically, it depends on battery chemistry, as demonstrated by the chart below, as well as battery size.
For example, the standard Tesla Model S contains about 138 pounds, or 62.6 kilograms, of lithium. It is powered by a NCA battery, which has a weight of 1,200 pounds or 544 kilograms.
The amount of lithium in a Tesla battery can also vary based on model and year as the battery chemistries and weights are often changing with each new iteration.
Back in 2016, Musk said batteries don't require as much lithium as they do nickel or graphite — he described lithium as "the salt in your salad." As the chart below shows, the metal only makes up about a 10th of the materials in each battery.
Metal content of battery chemistries by weight.
Chart via BloombergNEF.
But a key factor to remember is volume — given the amount of batteries Tesla needs to meet its ambitious goals, it could hit a bottleneck if it can’t secure a steady supply of raw materials. Of course, this is true not just for Tesla, but for every carmaker producing EVs today and setting targets for decades to come.
For that reason, demand for lithium-ion batteries is expected to soar in the coming years. By 2030, Benchmark Mineral Intelligence forecasts that demand will grow by 400 percent to reach 3.9 terawatt-hours. Over the same forecast period, the firm sees the current surplus in the lithium supply coming to end.
Will Tesla buy a lithium mine?
For carmakers, securing lithium supply to meet their electrification goals is becoming a challenge, which is why the question of whether they will become miners in the future continues to come up.
But mining lithium is not easy, and despite speculation, it's hard to imagine an automaker being involved in it, SQM’s (NYSE:SQM) Felipe Smith said. “You have to build a learning curve — the resources are all different, there are many challenges in terms of technology — to reach a consistent quality at a reasonable cost,” he noted. “So it's difficult to see that an original equipment manufacturer (OEM), which has a completely different focus, will really engage into these challenges of producing.”
Even so, OEMs are coming to the realization that they might need to build up EV supply chains from scratch after the capital markets' failure to step up, Benchmark Mineral Intelligence’s Simon Moores believes. Furthermore, automotive OEMs that are making EVs will in effect have to become miners.
“I don't mean actual miners, but they are going to have to start buying 25 percent of these mines if they want to guarantee supply — paper contracts won't be enough,” he said.
However, Musk has made it clear to investors that Tesla is more focused on developing its lithium refining capabilities, rather than getting into the mining game.
Where is Tesla's lithium refinery?
Tesla broke ground on its in-house Texas lithium refinery in the greater Corpos Christi area of the state in 2023. Tesla's lithium refinery capacity is expected to produce 50 GWh of battery-grade lithium per year. Construction of the lithium refinery is nearly completed with full production anticipated in 2025.
Tesla's Texas lithium refinery was facing an obstacle in obtaining a contract for the 8 million gallons of water per day needed to run the plant, as the region of South Texas is in the middle of a serious drought and water supplies are tight.
"In December, South Texas Water Authority passed an infrastructure deal that will allow Nueces Water Supply to sell rights to the pipe Tesla will need to obtain water, which was one of the hold-ups for a water deal," Bloomberg BNN reported in early January.

Laguna Verde Resource Update
CleanTech Lithium PLC ("CleanTech Lithium" or "CleanTech" or the "Company") (AIM: CTL, Frankfurt:T2N), an exploration and development company advancing sustainable lithium projects in Chile, announces an updated resource estimate for its Laguna Verde project that has been included by the Chile Government as one of the six salar systems to be prioritised for development.
Highlights:
- The mineral resource estimate is updated from that reported in the RNS of 17 July 2023 based on additional exploration and pumping tests conducted in 2024
- The JORC (2012) compliant estimate was calculated by Montgomery & Associates ("Montgomery´"), a leading hydrogeological consultant highly experienced in lithium brine resource estimation
- The total updated resource is 1.63 million tonnes of Lithium Carbonate Equivalent (LCE), at a grade of 175 milligrams per litre (mg/l) lithium, of which 0.81 million tonnes is in the Measured + Indicated category at a grade of 178 mg/l lithium
- This current resource estimate is based on the proposed polygon area included in the Company´s recently submitted application for a Special Operating Contract for Lithium ("CEOL")
- The previous 2023 estimate which totalled 1.77 million tonnes LCE at an average grade of 200mg/l lithium was based on the previously proposed CEOL area under the old application regime that was larger covering the entire estimated resource of the basin.
- Lithium concentrations obtained in the 2024 campaign were below the average grade of other exploration wells impacting the average lithium grade of the resource
- Montgomery recommends three additional drillholes in the southwest, north and northeast to potentially increase the resource based on completed geophysics
- This updated measured and indicated resource estimate will be used in the pre-feasibility study (PFS) which is intended to underpin a maiden reserve estimate for the Laguna Verde project
Steve Kesler, Executive Chairman, CleanTech Lithium said: "The updated JORC-compliant resource estimate for the Laguna Verde project, independently determined by Montgomery & Associates, confirms a robust and significant resource of 1.63 million tonnes of Lithium Carbonate Equivalent (LCE), with 0.81 million tonnes in the Measured and Indicated category at an average grade of 178 mg/l lithium. Now with greater confidence in the resource, this comprehensive evaluation will form the basis for the Pre-Feasibility Study, scheduled for end of this quarter. This positions Laguna Verde as a highly promising direct lithium extraction (DLE) based project in the lithium brine sector and as a contributor to Chile's future as a leading lithium producer for the global EV and battery market."
Further Details:
Project Background
The Laguna Verde corresponds to a lithium brine deposit which is found in the Atacama Region of Chile, near the Chile - Argentina border. The project consists of mining concessions located approximately 192 kilometres (km) northeast of Copiapó. The concession area is readily accessible via a network of paved roads from the closest major city Copiapó, following the route (R-31) for approximately 275 km. The Laguna Verde Basin has elevations that vary between 4,330 to 4,500 metres above sea level (masl), where the low altitude valley area is approximately 20 km long and 4 km wide.
Figure 1: Regional Location Map and Project Area
The previous resource estimate for Laguna Verde was reported in July 2023, based on five wells completed in 2022 and 2023. A drill programme was undertaken in 1H 2024 which completed two infill wells in the first half of 2024 along with three observation wells drilled to support observations during pumping tests. The location of wells completed from 2022 - 2024 are shown in Figure 2, along with three recommended wells to potentially increase the resource.

Resource Summary
Montgomery was engaged to support the 2024 field programme at Laguna Verde and based on the information obtained to provide an updated resource estimate and technical report for the project. The technical report has been prepared to conform to the regulatory requirements of the JORC Code (2012). Mineral Resources are also reported in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Best Practice Guidelines (CIM, 2012).
The breakdown of the resource categories comprising the total resource estimate and the comparison with the previous 2023 estimate is shown below in Table 1. The previous 2023 estimate which totalled 1.77 million tonnes LCE at an average grade of 200 mg/l Lithium was based on a proposed CEOL area that was larger and covered the entire estimated resource of the basin, whereas the updated 2025 estimate is based on the Company's preferential licences and proposed polygon area included in the Company´s recently submitted application for a CEOL. As a comparison, the current resource estimate for the basin (on the same basis of larger CEOL area) would be 1.95 million tonnes LCE.
Lithium concentrations obtained in the 2024 campaign were below the average grade of other exploration wells impacting the average lithium grade. Although slightly lower than the lithium grade used in the 2023 scoping study a grade of 175 mg/l lithium is very suitable for the DLE process and is well above the cut-off grade of 100 mg/l lithium.

Special Operating Contract for Lithium (CEOL)
In April 2024 the Chilean government announced, as part of its National Lithium strategy, the intention to make available to the private sector CEOLs over 26 salt flats. As of September 2024, the Chilean government has prioritised six salt flats for the CEOL award process, one of which is Laguna Verde. The CEOL grants exclusive rights to exploit lithium and only one CEOL is to be granted per saline system. The Government also published a polygon CEOL area for each of the prioritised salt flats but clarified that this polygon area is referential and could be modified following community dialogue and with agreement of the applicant. The Government also announced that the CEOL could be awarded in a streamlined procedure that allowed direct negotiation with Government rather than through a public tender provided that a number of criteria were met. One criteria was that the applicant must demonstrate that it holds at least 80% of the preferential mining licences in the CEOL polygon.
CleanTech Lithium has proposed a modification to the published CEOL polygon in its CEOL application (shown in Figure 3) which has been developed to ensure that over 80% of the proposed CEOL polygon area is preferential mining licenses held by CleanTech. The CEOL application by CleanTech includes letters of support from indigenous communities for the proposed modified CEOL polygon.
Figure. 3: CleanTech´s Preferential Licences and Proposed CEOL Extent
Table 2 provides a breakdown of the current Laguna Verde resource estimate by resource category and by separating the resource attributable to the preferential licences held by the Company, and the provisional resources in licences held by third parties within the proposed CEOL area. The combined resource would be attributable to the Company provided the CEOL is awarded to CleanTech for the proposed area (Figure 3).
Mineral resources are not mineral reserves and do not have demonstrated economic viability. Furthermore, not all mineral resources can be converted into mineral reserves after application of the modifying factors, which include but are not limited to mining, processing, economic, and environmental factors.
Table 2: Mineral Resource Estimate for the Laguna Verde Project (Effective January 3, 2025)
Resource Estimation Method
The updated resource estimate consists of Measured, Indicated and Inferred resources. A detailed geological and resource block model was creating in Leapfrog (Seequent, 2023) using obtained well lithologies, discrete-depth values for brine chemistry, drainable porosity values, and geophysical profiles. Lithium concentrations were interpolated using ordinary kriging, specific yield was assigned to each hydrogeological unit, and the mass calculations within the resource block model were undertaken using the Leapfrog Edge extension. A cut-off grade of 100mg/l lithium was conservatively applied based on the Laguna Verde scoping study capital and operating costs.
Consistent with the Houston et al. (2011) recommendations for immature salars, a 1.25 km radius circle around the well was used to estimate a Measured resource, a 2.5 km radius circle around the well was used to estimate an Indicated resource, while a maximum 5 km radius circle was used as the areal extent to estimate an Inferred resource. Depending on the confidence in the sampling procedures and presence of volcanic outcrops, some resource polygons were limited in extent.
Surface Rights
In Chile, Surface Access Rights should be granted or imposed on a mining concession before the extraction starts. CleanTech Surface Access Rights request was received by Bienes Nacionales on June 16, 2023, in the name of Atacama Salt Lakes SpA and is currently in process. The requested area totals 11,136 hectares and covers the project scoping study planned installations (Ad Infinitum, December, 2022). The requested area can be seen in Figure 4.

Water Rights
There are surface water courses that contribute to the Laguna Verde. The Peñas Blanca River flows from west to east and has a continuous flow throughout the year, while to the east of the Laguna Verde, there are intermittent surface water flows. Freshwater exploration wells also exist in the western portion of the basin with demonstrated pumping rates that exceed 40 L/s (Hydro Exploraciones, 2020). Furthermore, a conceptual water balance of the basin recharge has been prepared and indicates that the average estimated freshwater recharge in the Laguna Verde Basin corresponds to 570 l/s (M&A, 2024a). Potential sources of freshwater for the Project include the application for groundwater rights in the basin or the purchase of water rights from third parties (CleanTech, 2024).
Geological Setting
The regional geology of the Project area is mainly characterised by volcanic and sedimentary sequences. Laguna Verde is an immature clastic salar basin, with the lagoon effectively corresponding to the evaporative "salar nucleus". The Project consists of a lithium-rich aquifer found below the lagoon and in the surrounding sediments. The brine is mainly hosted in volcaniclastic sediments and tuff beneath the lagoon with a moderate hydraulic conductivity.
The Laguna Verde stratigraphy is characterised by a band of tuffs with different grain sizes, consolidation / welding, type of clasts, and locally interbedded volcaniclastic sediments. This unit presents an average thickness of 400 metres and overlays the lower volcanic rock (mainly andesite) identified in drillholes and the gravity survey, which has some fracturing and a low drainable porosity. Furthermore, a fault zone which has highly fractured and brecciated rock was encountered along the southern portion of Laguna Verde. In all, the brine aquifer was characterised up to a maximum depth of 650 metres (LV07).
Figure 5 shows the locations for two NW-SE hydrogeological cross sections, and Figure 6 shows the sections with the hydrogeological units modelled in the Leapfrog software.

Exploration
CleanTech engaged Geodatos to conduct Transient ElectroMagnetic (TEM) geophysical surveys at Laguna Verde during the periods April to May 2021 and again in March 2022. The objective of these surveys was to determine the electrical properties of the subsurface sediments to provide information about the stratigraphy and water quality of the hydrogeologic units in the area. The surveys also helped determine the water table level and helped confirm the presence of brine.
A gravity survey was performed by Geodatos between the end of December 2022 and early January 2023. The survey campaign included TEM measurements and two extra profiles. One hundred and eleven (111) gravity stations, arranged in four lines surrounding the lagoon area, as well as fourteen (14) TEM stations, arranged in two lines, were surveyed with a 400-metre separation.

Drilling
An initial drilling campaign was conducted in 2022 and 2023 with four diamond drill holes (DDH) (LV01, LV02, LV03 and LV04) and two rotary wells (LV05 and LV06) as shown in Figure 2. A second campaign was conducted in 2024, with Montgomery personnel, where two exploration boreholes were drilled (LV07 and LV11) with monitoring wells for subsequent pumping tests at LV05 and LV06. Drilling at boreholes LV07 and LV11 reached a final depth of 650 metres below land surface (mbls) and 412.8 mbls, respectively. A pumping test at LV05 was initially conducted in the first campaign and included a pre-test and a 48-hour constant discharge test on April 8, 2023. During the 2024 campaign, a step-discharge and a constant-discharge were conducted at LV05, but due to adverse weather conditions, a long-term constant rate test could not be completed. During the first campaign, a pre-test and a constant discharge test were conducted at LV06 and a long-term (7-day) constant rate test was conducted during the 2024 campaign.

Brine Sampling Collection and Analysis
Various methods were used to obtain brine samples during and after the exploration drilling program:
- Packer sampling
- Airlift sampling
- Double-valved disposable bailer sampling
- Double-valved electric bailer sampling
- Hydra-sleeve sampling
- Brine sampling during pumping tests
The brine sampling program included standard quality assurance/quality control (QA/QC) elements such as including duplicate brine and blank samples in bine sample batches sent to the laboratory. Formal traffic reports and chain of custody documents were prepared for every sample obtained and submitted for laboratory analysis. In the opinion of the Competent Person (CP), sample preparation, security, and analytical procedures were acceptable for this stage of the Project and results from the laboratory analyses are considered adequate.
Drill Core Sampling and Specific Yield Estimation
During the first campaign, core samples were obtained every 10 metres from the four drillholes and a total of 122 core samples were obtained at each drillhole and submitted to the DBS&A Laboratory in New Mexico, USA for Relative Brine Release Capacity (RBRC) tests. During the second campaign (2024), 33 core samples were obtained from LV07 and LV11 and were sent to GeoSystem Analysis (GSA) laboratory in Tucson, USA, for analysis.
Figure 9: Example of Drill Core from Exploration Borehole LV11 (132 to 136m)
Laboratory values for drainable porosity were obtained from 145 successfully analysed core samples. Core samples underwent Relative Brine Release Capacity (RBRC) tests. The drainable porosity (i.e., specific yield) measurement procedure involved saturating the core sample with a brine solution and placing them in test cells where a pressure differential was applied and the proportion of brine which can be drained was estimated. In the opinion of the CP, sample preparation, security, and analytical procedures were acceptable and results from the laboratory analyses are considered adequate for resource estimation. The 2023 resource estimate included drainable porosity measurements which were increased by a secondary porosity term calculated from rock quality designation logged during drilling. This current resource update uses drainable porosity measurements from the laboratory, without modification, which results in lower drainable porosities than used in the 2023 resource estimate.
The average drainable porosity values assigned to each hydrogeologic unit used to estimate the lithium resource are given in Table 3. Due to its smaller dataset, a simpler analysis was undertaken for drainable porosity to assign representative values by hydrogeological unit; constant (average) values were assigned to each hydrogeologic unit in the resource model, and drainable porosity values were not interpolated.
Table 3: Assigned Drainable Porosity Values for Laguna Verde Hydrogeological Units
Hydrogeological Unit | Average Drainable Porosity* | N° Samples |
Unconsolidated Tuff and Coarse Tuff | 6% | 102 |
Consolidated Ash Tuff | 3% | 14 |
Brecciated and Fractured Rock | 5% | 9 |
Lower Volcanic Rock | 1% | 5 |
Upper Alluvium and Colluvium | 10%** | 0 |
Surficial Volcanic Deposits | 3%*** | 0 |
* Rounded arithmetic average
** Assumed theoretical value
*** The drainable porosity of the consolidated ash tuff unit was assumed due to its lithological similarity. The number of blocks that correspond to the consolidated ash tuff within the resource block model are negligible compared to the rest of the hydrogeological units.
Recommendations
Currently, the drilling and testing of a reinjection well is planned for the first quarter of 2025. In terms of the resource, three additional diamond drillholes in the southwest, north, and northeast are recommended to potentially expand the resource volume (Figure 2; LV08, LV09, and LV10) based on the conducted geophysics. During the drilling of those three additional diamond drillholes, depth-specific brine and drainable porosity sampling are recommended with the corresponding QA/QC measures.
Block Model Results and Verification
Figure 10 presents the shallowest interpolated concentrations of the brine body which were mapped to the Leapfrog block model; as can be seen, grades are highest in the western portion of Laguna Verde, whereas the eastern portion represents a zone of heightened recharge with diluted grades. The bottom of the block model was limited to the deepest well (LV07), and the horizontal extent of the block model was limited to the CleanTech concessions and potential of the proposed CEOL area. Laboratory results for lithium concentrations from depth specific brine and pumping test samples collected from the wells were incorporated directly into the model. Ordinary Kriging was used for the interpolation of lithium concentrations within the block model.
Figure 10: Shallow Lithium Concentration Distribution and Proposed CEOL Outline
The resource block model was subsequently validated by visual inspection and comparison of the measured and block model concentrations. Swath plots were also utilized, which compare the average measured and interpolated values along distinct profiles of the block model.
