Steve Kesler, Executive Chairman and Interim Chief Executive Officer, CleanTech Lithium PLC, said:
"With the recent announcement by the Chilean Government to prioritise six salt flats, including Laguna Verde, to start the process of awarding Special Operating Lithium Contracts (CEOLs), we are focused on the key aspects to advance the project, being permitting, completion of the PFS and production of battery grade lithium carbonate from our pilot plant.
Progress has continued on central elements of the PFS with evaluation of plant location, power supply and transport options. As a leader in developing DLE based projects in Chile, we aim to enter production in 2027 when the lithium market is expected to rebalance, providing a strong long term growth outlook."
Further Information
Sites Selected for Carbonation Plant and Port for Export of Final Product
As part of the ongoing PFS for the Laguna Verde project, a trade-off analysis was completed which determined the DLE plant and eluate concentration stages should be located at the Laguna Verde site, and the carbonation plant at the nearby mining centre of Copiapó. This was reported to the market on July 2, 2024. The re-configuration required a change in pre-engineering design provided by Lanshen Technology, the Company selected to provide the lithium processing plant design and equipment. This has extended the expected PFS completion, which was originally targeted for Q4 2024, into Q1 2025.
The Company has since undertaken studies to determine the ideal location of the carbonation plant in Copiapó and selected a site. After evaluating several options, a site in an industrial zone which by-passes to the south-east of Copiapó was chosen, as shown in Figure 1. This location has existing power and water supply options and provides a direct route to port.
Figure 1: Carbonation Plant Location Map
Figure 2: Carbonation Plant Design Layout
A trade-off analysis was undertaken to evaluate transport corridors and port facilities providing four different options for export of final lithium product. The study indicated that the nearby Caldera Port provides the most suitable option either utilising existing infrastructure which is currently utilised for seasonal shipment of agricultural products, shown in Figure 3. Other port options are also available and may come into consideration however Caldera Port is the current preference.

Power Supply Alternative of Onsite Renewable Generation
The Company engaged Chilean consultant Clean Power Hunters to undertake a power supply study to evaluate the option of using renewable power generated at the project site as an alternative to the base case of a transmission line and grid connection. Laguna Verde is located in the region with the highest solar irradiance in the world, as shown in Figure 4. Analysis of estimated Capex and Opex was provided based on different configurations of onsite renewables, either solar plus a battery energy storage system (BESS) or solar plus wind plus BESS. Figure 5 shows the lowest Capex corresponds to combining solar with three wind turbines plus BESS.
Figure 4: Solar Irradiance Map
Figure. 5: Solar + Wind + BESS Scenarios Capex Split
The Company has received proposals including from major global solar plus BESS suppliers, consistent with the costs estimated in the study and competitive with the grid connection option. The financing model for both the grid connection model or the alternative of onsite renewables is expected to be based on a power purchase agreement and a build own operate basis by established suppliers. These proposals will be built into the PFS and the commercial analysis of the project.
Truck Transport Study
Based on the outcome of the plant location study the Company will transport 6% Li in solution post the DLE and concentration stages at Laguna Verde to the carbonation plant. Use of standard and electric trucks is being compared with the latter providing several potential benefits in addition to cutting CO2 emissions. Electric trucks are well suited to hauling loads from high to low altitudes by taking advantage of regenerative charging to reduce power consumption and required battery capacity. Minimal noise and elimination of tailpipe emissions is particularly attractive considering the transport route traverses an indigenous community settlement approximately 100km from the project site, a community the company has been working with closely.
The Company has gathered insight from several potential suppliers. Chinese company XCMG is a leader in electric trucks and is actively expanding its offering in Chile, with its E7-49T model which has a haulage load of 49 tonnes potentially providing a suitable option. The technology is evolving rapidly and is expected to provide a strongly cost competitive option in line with the project development timeline.

2024 Exploration Programme Update
CleanTech Lithium´s 2024 drilling programme anticipated to drill five new resource wells, as shown in Figure 8, with the aim of upgrading the existing Measured and Indicated resource into maiden Reserves for the Laguna Verde project. The existing JORC compliant resource estimate of 1.8 million tonnes of lithium carbonate equivalent (LCE) is based on six wells completed in 2022 and 2023. The Company engaged Montgomery & Associates Consultores Limitada ("Montgomery" or "M&A"), a leading hydrogeological consultant, for the programme. During 1H 2024, two of the five resource wells were completed being LV07 and LV11, along with three observation wells drilled to support observations during pumping tests, before winter conditions curtailed the programme in June 2024. The full 2024 programme is paused until further funding is available following the Company´s planned ASX fund raising and as a result Montgomery has produced an interim report on work completed.
Figure 8: Laguna Verde Drilling Wells Map - Show original figure
Drilling activities for exploration borehole LV07 reached a final depth of 650m below land surface. This well was drilled with PQ3 diameter from land surface to 300m, and with HQ3 diameter from 300m to 650m. Packer samples were obtained during drilling for 2-meter packer intervals and the volume of the well was purged at least one time before obtaining the sample. Assuming a lithium cut-off grade of 100 mg/L, the average lithium grade of the packer samples corresponds to 139 mg/L with the well encountering lower density water in the upper 150m.
In contrast to LV07, drilling at LV11 did not reach the anticipated depth due to the presence of hydrothermal waters (under pressure) which were encountered during drilling, with a final depth of 412.8m below land surface. Assuming a lithium cut-off grade of 100 mg/L, the average lithium grade of the packer results would correspond to 131 mg/L. In general, it is believed that lithium grades decrease below 220m at LV11 due to the presence of dilute hydrothermal waters which were encountered during drilling. The presence of hydrothermal waters in the eastern portion of the Project are more dilute than the average lithium grade measured in other exploration wells.
Figure 9: Drilling at LV07 in 1H 2024
Lithology and Drainable Porosity
Based on core retrieved from drilling, the most predominant lithology encountered corresponds to a volcanic tuff with variable levels of consolidation and welding based on the depth and location. As determined by relative brine release testing at Geosystems Analysis (GSA) laboratory in Tuscon, USA, drainable porosity values of collected core samples from LV07 and LV11 range from 0.3% to 9.2%, with an arithmetic average of approximately 4%; this is considered by Montgomery to be reasonable for the encountered lithologic units based on visual inspection of the core.
Figure 10: Example of Drill Core from Exploration Borehole LV11 (132 to 136m)
Hydrogeological Evaluation
In addition to resource drilling, the 2024 campaign aimed to complete pump tests to evaluate the feasibility of lithium brine extraction for the Project and to also estimate aquifer parameters. Prior to the winter break, three observation wells were completed and initial variable rate step tests and a constant rate flow test undertaken. The intended long duration pump tests at well LV05 was not able to be completed, however a 7-day pumping test was successfully completed at LV06. With data obtained to date, Montgomery is able to continue refining the hydrogeological modelling that will feed into the design of the extraction and reinjection well fields for the PFS. A key aspect is to ensure no impact on surface water bodies.
Recommendations and Next Steps
Based on the obtained results from the 2024 exploration programme, recommended priorities for continued exploration include additional drilling and testing in the western portion of the Project concessions. A long-term pump test at LV05 (as part of the planned reinjection test) will also aid in demonstrating feasible extraction and reinjection to the west of the basin. A long-term test at LV05 will also allow for a better understanding of the hydraulic connection between the deep and shallow aquifers in that area.
On the completion of the 5 well programme as originally planned for 2024, the existing JORC compliant resource estimate of 1.8 million tonnes will be updated and a Reserve estimate will be calculated for the project. The Reserve calculation is the economically mineable part of the Measured and/or Indicated resource and this will be defined by the PFS data demonstrating that extraction could reasonably be justified. Progress continues on the PFS and the remaining planned wells will be completed as funds are available following completion of the planned ASX capital raising.
Pilot Plant Update
Downstream conversion of concentrated eluate from the Company´s pilot plant into battery grade lithium commenced last week at the facilities of Conductive Energy in Chicago, USA. The initial volume of 88m3 of concentrated eluate from Laguna Verde, equal to approximately one tonne of lithium carbonate equivalent ("LCE"), will be processed in four batches with the first batch expected to produce a volume of battery-grade sample product in November. With this product, the Company plans to engage with strategic partners for product qualification.

Jindalee Lithium
Investor Insight
With compelling economic metrics demonstrated through its new prefeasibility study, Jindalee Lithium’s McDermitt Project presents a strong case for investors to gain exposure to this critical mineral and participate in the global clean energy transition.
Overview
Jindalee Lithium (ASX:JLL,OTCQX:JNDAF) is an Australia-based pure-play US lithium company focused exclusively on its 100-percent-owned McDermitt Lithium Project, currently one of the largest lithium deposits in the US, boasting a resource of 21.5 million tons (Mt) of lithium carbonate equivalent (LCE).
Backed by a newly released (November 2024) prefeasibility study (PFS) demonstrating very compelling economics, the McDermitt Project is poised to play a crucial role in meeting North America’s growing lithium demand for the lucrative battery value chain.
As the US continues to transition to energy independence, demand for lithium is expected to exponentially increase. Jindalee’s McDermitt Project, located in southeast Oregon, is a game-changer for North American lithium supply, critical for meeting the demands of the fast-growing electric vehicle, energy storage and defense sectors.
McDermitt also stands to significantly benefit from the US government’s policies and incentives to boost domestic supply of critical resources. In fact, in a move that signifies the US government's support of the McDermitt Lithium Project, the US Department of Energy's Ames National Laboratory signed a Cooperative Research and Development Agreement with Jindalee's subsidiary HiTech Minerals to develop cutting-edge extraction methods for the McDermitt Project. The Ames National Laboratory spearheads the DOE's Critical Materials Innovation Hub.
Key milestones in the US lithium resource space also provide significant insights into the future prospects for Jindalee’s project. Lithium Americas (TSX:LAC), for instance, has received a total of US$945 million investment from General Motors, which will fund the development, construction and operation of the Thacker Pass project in Humboldt County, Nevada. In October 2024 LAC closed a $2.3 billion loan from the US Department of Energy and in April 2025 announced the Final Investment Decision for Thacker Pass following a $250 million investment from Orion Resource Partners.
Another lithium resource developer in Nevada, Australia-based Ioneer (ASX:INR) has closed a US$996 million loan guarantee from the US Department of Energy to finance the development of its flagship Rhyolite Ridge lithium-boron project.
The US government has taken further action to bolster domestic critical mineral production. On 20 March 2025, President Trump issued a significant executive order titled "Immediate Measures to Increase American Mineral Production", underscoring the urgency and strategic imperative of increasing domestic supply chains for critical minerals. This order builds on previous initiatives by fast-tracking the permitting processes, prioritizing access to mineral-rich federal lands, clarifying regulatory frameworks, and mobilizing substantial financial resources – including Defense Production Act (DPA) funds – towards domestic mineral projects.
As one of the largest lithium resources in the US and situated on federal lands, Jindalee’s McDermitt Lithium Project stands to potentially benefit from these accelerated permitting processes and enhanced government support mechanisms. The clear commitment demonstrated by the US administration highlights the critical strategic advantage of domestically located mineral assets such as McDermitt, reinforcing its importance in securing robust domestic supply chains, essential for energy security
These are just a few examples of current market dynamics that point to a rapidly accelerating lithium resource development in the US.
An experienced management team, with the right blend of experience and expertise in geology, corporate administration and international finance, leads Jindalee to fully capitalize on the potential of its assets.
Company Highlights
- Jindalee Lithium is focused on its wholly owned flagship McDermitt Lithium Project, one of the largest lithium deposits in the US.
- McDermitt’s new prefeasibility study shows strong project economics, including a US$3.23 post-tax NPV8 based on the first 40 years of a 63 year-year mine life.
- Jindalee is committed to strengthening the North American critical minerals supply chain by reducing US reliance on foreign lithium, thereby enhancing energy security.
- The company’s wholly owned US subsidiary HiTech Minerals Inc, has executed a strategic Cooperative Research and Development Agreement (CRADA) with Ames National Laboratory, which leads the US Department of Energy’s (DOE) Critical Materials Innovation (CMI) Hub.
- The company’s McDermitt deposit is sediment-hosted, an emerging style of lithium deposit with the potential to be a large scale, long-life, low-cost source of lithium.
- Ideally positioned to benefit from US administration’s push to increased domestic mineral production via permitting reformed increased funding.
- An experienced management team leads Jindalee towards capitalizing on the potential of its assets.
Key Project
McDermitt Lithium Project Economics
The economic metrics revealed in the PFS paint a compelling picture of the McDermitt Lithium Project's potential:
Production Capacity: The Project is set to produce 1.8 Mt of battery-grade lithium carbonate over its first 40 years, with an annual output forecast of 47,500 tons per annum (tpa) in the initial 10 years, tapering to 44,300 tpa over the first 40 years.
Financial Metrics: The Project boasts a net present value (NPV) of US$3.23 billion at an 8 percent discount rate, with an internal rate of return (IRR) of 17.9 percent. These figures underscore the Project’s strong economic viability.
Payback Period: Investors can expect a payback period of less than five years, a relatively short timeframe for a project of this magnitude.
Break-even Price: The break-even NPV price is approximately US$14,600/t of lithium carbonate, providing a buffer against market fluctuations.
The PFS estimates a total project cost of US$3.02 billion, which includes a prudent 21 percent contingency margin. This substantial investment is balanced by impressive profitability projections, including an EBITDA margin of 66 percent generating post-tax free cash flow of US$6.6 billion during the first decade of operations. With a pre-tax net operating cashflow margin of 17 percent at current spot prices, McDermitt shows strong cash generation potential.
These financial indicators suggest that McDermitt is not only economically viable but potentially highly profitable, positioning it as an attractive prospect for investors and strategic partners alike.
Project Overview
The McDermitt Project is located in Malheur County on the Oregon-Nevada border and is approximately 35 kilometres west of the town of McDermitt. The 100-percent-owned asset covers 54.6 square kilometres of claims at the northern end of the McDermitt volcanic caldera.
The Project is characterized by its unique sedimentary lithium deposits, primarily composed of lithium-bearing clays, a geological formation that sets McDermitt apart from many other lithium projects worldwide. This sedimentary nature of the deposit offers several advantages:
- Consistent grade distribution throughout the ore body
- Potential for large-scale, low-cost mining operations
- Amenability to environmentally friendly extraction methods
The lithium-rich clays at McDermitt are part of a broader geological context that includes volcanic tuffs and sedimentary rocks. This geological setting is indicative of a complex depositional history, which has resulted in the concentration of lithium in economically viable quantities.
The 2023 mineral resources estimate (MRE) for the McDermitt Project contains a combined indicated and inferred mineral resource inventory of 3 billion tons at 1,340 parts per million (ppm) lithium for a total of 21.5 Mt LCE at 1,000 ppm cut-off grade.
Project Highlights:
- Rare Sediment-hosted Lithium Deposits: The McDermitt asset supports low-cost mining operations due to its flat-lying sediments. This type of lithium deposit is amenable to low-cost mining operations, while still producing excellent metallurgical results.
- A 62 percent resource increase in early 2023: Compilation of the 2022 drilling results saw the estimated indicated and inferred resources at McDermitt increase to 3 billion tons at 1,340 ppm lithium, a 62 percent increase in contained lithium.
- Fluor recommended processing route: In March 2023, US engineering group Fluor reviewed all testwork undertaken at McDermitt and recommended beneficiation and acid leaching as the optimal processing route.
- Battery-grade lithium carbonate successfully produced in July 2024: The production is an important milestone validating all steps of the processing flowsheet for the project from ore beneficiation and leaching to purification and production of battery-grade lithium carbonate.
- Completion of the PFS outlines large scale, long life and low cost source of American made battery grade lithium chemicals (November 2024)

CleanTech Lithium
Investor Insight
Executing a well-defined project development strategy for its lithium assets and advancing Direct Lithium Extraction (DLE), CleanTech Lithium is poised to become a key player in an expanding batteries market.
Overview
CleanTech Lithium (AIM:CTL,FWB:T2N) is a resource exploration and development company with four lithium assets with an estimated 2.72 million tons (Mt) of lithium carbonate equivalent (LCE) in Chile, a world-renowned mining-friendly jurisdiction. The company aims to be a leading supplier of ‘green lithium’ to the electric vehicle (EV) market, leveraging direct lithium extraction (DLE) – a low-impact, low-carbon and low-water method of extracting lithium from brine.
Lithium demand is soaring as a result of a rapidly expanding EV market. One study estimates the world needs 2 billion EVs on the road to meet global net-zero goals. Yet, the gap between supply and demand continues to widen. As the world races to secure new supplies of critical minerals, Chile has emerged as an ideal investment jurisdiction with mining-friendly regulations and a skilled local workforce to drive towards a clean green economy. Chile is already the biggest supplier of copper and second largest supplier of lithium.
With an experienced team in natural resources, CleanTech Lithium holds itself accountable to a responsible ESG-led approach, a critical advantage for governments and major car manufacturers looking to secure a cleaner supply chain.
Laguna Verde is at pre-feasibility study stage targeted to be in ramp-up production from 2027. Laguna Verde has a JORC resource estimate of 1.8 Mt of lithium carbonate equivalent (LCE) while Viento Andino boasts 0.92 Mt LCE, each supporting 20,000 tons per annum (tpa) production with a 30-year and 12-year mine life, respectively. The latest drilling programme at Laguna Verde finished in June 2024, results from which will be used to convert resources into reserves.
The lead project, Laguna Verde, will be developed first, after which Veinto Andino will follow suit using the design and experience gained from Laguna Verde, as the company works towards its goal of becoming a significant green lithium producer serving the EV market.

- Environmentally Friendly Extraction: The company’s asset is amenable to DLE. Instead of sending lithium brine to evaporation ponds, DLE uses a unique process where resin extracts lithium from brine, and then re-injects the brine back into the aquifer, with minimal depletion of the resources. The DLE process reduces the impact on environment, water consumption levels and production time compared with evaporation ponds and hard-rock mining methods.
- DLE Pilot Plant: The pilot DLE plant in Copiapó, commissioned in the first quarter of 2024, has produced an initial volume of 88 cubic metres of concentrated eluate, which is the lithium carbonate equivalent (LCE) of approximately one tonne further confirming the company’s capacity to produce battery-grade lithium with low impurities from its Laguna Verde brine project.
- Scoping Study: Scoping study completed in January 2023 indicated a production of 20,000 tons per annum LCE and an operational life of 30 years. Highlights of the study also includes:
- Total revenues of US$6.3 billion
- IRR of 45.1 percent and post-tax NPV8 of US$1.8 billion
- Net cash flow of US$215 million
Viento Andino Lithium Project
CleanTech Lithium’s second-most advanced asset covers 127 square kilometers and is located within 100 km of Laguna Verde, with a current resource estimate of 0.92 Mt of LCE, including an indicated resource of 0.44 Mt LCE. The company’s planned second drill campaign aims to extend known deposits further.
Project Highlights:
- 2022 Lithium Discovery: Recently completed brine samples from the initial drill campaign indicate an average lithium grade of 305 mg/L.
- JORC-compliant Estimate: The inferred resource estimate was recently upgraded from 0.5 Mt to 0.92 Mt of LCE at an average grade of 207 mg/L lithium, which now includes 0.44 million tonnes at an average grade of 221 mg/L lithium in the indicated category.
- Scoping Study: A scoping study was completed in September 2023 indicating a production of up to 20,000 tons per annum LCE for an operational life of more than 12 years. Other highlights include:
- Net revenues of US$2.5 billion
- IRR of 43.5 percent and post-tax NPV 8 of US$1.1 billion
- Additional Drilling: Once drilling at Laguna Verde is completed in 2024, CleanTech Lithium plans to commence further drilling at Viento Andino for a potential resource upgrade.
Llamara Lithium Project
The Llamara project is one of the largest greenfield basins in the Lithium Triangle, covering 605 square kilometers in the Pampa del Tamarugal, one of the largest basins in the Lithium Triangle. Historical exploration results indicate blue-sky potential, prompting the company to pursue additional exploration.
Project Highlights:
- Promising Historical Exploration: The asset has never been drilled; however, salt crust surface samples indicate up to 3,100 parts per million lithium. Additionally, historical geophysics lines indicate a large hypersaline aquifer. Both of these exploration results indicate potential for significant future discoveries.
- Close Proximity to Existing Operations: The Llamara project is near other known deposits:
Arenas Blancas
The project comprises 140 licences covering 377 sq km in the Salar de Atacama basin, a known lithium region with proven mineable deposits of 9.2 Mt and home to two of the world’s leading battery-grade lithium producers SQM and Albermarle. Following the granting of the exploration licences in 2024, the Cleantech Lithium is designing a work programme for the project

American Salars: Building a Diversified Portfolio of Lithium Assets Across the Americas
American Salars Lithium (CSE:USLI,OTC:USLIF, FWB:Z3P) is an exploration-stage company dedicated to acquiring, developing, and monetizing lithium brine projects across the Americas. With a clear focus on low-cost entry and scalable resource expansion, the company is executing a disciplined strategy to build a high-quality portfolio in strategic jurisdictions.
Central to American Salars’ vision is the conviction that lithium demand—driven by the accelerating adoption of electric vehicles and the rise of stationary energy storage solutions—is poised for significant long-term growth. The company is strategically positioning itself to capitalize on this trend, targeting assets with strong appeal to major producers and institutional investors.
Salar de PocitosSalar de Pocitos is the flagship asset of American Salars Lithium, situated in Argentina’s lithium-rich Puna region within Salta Province. The Pocitos 1 block spans 800 hectares and has shown strong lithium brine potential through historical drilling and testing. While a 760,000-ton inferred lithium carbonate equivalent (LCE) resource was previously reported for the area—including Pocitos 2, which is not owned by American Salars—all contributing drill holes for that estimate were located within Pocitos 1, where the company holds 100 percent ownership.
Drilling at Pocitos 1 has encountered aquifers at depths between 365 and 407 meters, with lithium concentrations reaching up to 169 parts per million (ppm). Sustained brine flow rates were recorded for over five hours, and porosity tests on core samples returned strong results, ranging from 6 to 14 percent, further underscoring the project’s potential.
Company Highlights
- American Salars Lithium is taking advantage of depressed lithium prices to acquire undervalued assets with long-term scalability and world-class exit potential. The company targets assets with clear upside potential, particularly in brine-rich jurisdictions like Argentina and Nevada.
- The company’s holdings include four lithium projects: Salar de Pocitos (Argentina), Black Rock South (Nevada, USA), Jaguaribe Pegmatite (Brazil), and the Quebec Lithium Portfolio (Canada).
- Located in the Lithium Triangle of Salta, Argentina, the flagship Pocitos 1 is an 800-hectare brine project shares a 760,000-tonne inferred lithium carbonate equivalent (LCE) resource and excellent expansion potential.
- Brine-based lithium resources offer lower environmental impact, faster resource delineation, and reduced development costs compared to hard rock alternatives.
- Several of the company’s team members have been involved in multi-million-dollar lithium asset sales. Recent deals in the region (e.g., Alpha Lithium, Neo Lithium, Arcadium) provide a roadmap for monetization.
