Galan Lithium
Overview
Argentina is no stranger to lithium mining. The South American nation is one of three encompassed in the prolific Lithium Triangle, a region that holds more than half of the world’s lithium deposits. Argentina ranks third in the world in terms of lithium reserves at 2.7 million metric tons (MT), concentrating lithium operations in the provinces of Jujuy, Salta and Catamarca.
Amidst electrification and decarbonization, analysts have forecasted a global supply deficit of 89,000 tons of lithium carbonate equivalent (LCE) in 2023 and the Argentinian government aims to double down on lithium to meet the increasing demand. Argentina has committed to $7 billion worth of investment for lithium production with strong growth projected for exports at $1.1 billion in 2023.
Galan Lithium (ASX:GLN,FSX:9CH) is an Australia-based international mining development company focused on its high-quality lithium brine projects in Argentina – Hombre Muerto West and Candelas. The company also holds a highly prospective lithium project in Australia – Greenbushes South.
The company’s flagship Hombre Muerto West (HMW) project hosts some of Argentina’s highest grade and lowest impurity levels with an inventory of 8.6 million tons (Mt) contained LCE @ 859 mg/L lithium, with 4.7 Mt contained LCE @ 866 mg/L Li in the measured category. The 100-percent-owned property also leverages close proximity to Livent Corporation’s El Fenix operation and Allkem’s Sal de Vida projects.
Galan has signed a commercial agreement with the Catamarca Government supporting the grant of permits to enable the commercialisation of lithium chloride concentrate from HMW to be sold locally or exported internationally.

Galan’s secondary Candelas project comprises a sizable valley-filled channel with a potential indicated presence of substantially high-volume brine characteristics. The project’s maiden resource estimates stand upwards of 685 kilotons (kt) LCE, based on surveying from October 2019, and demonstrate exceptional discovery opportunities across this underexplored asset. Candelas has been rolled into Phase 4 of Galan’s targeted expansion plans, towards 60 ktpa LCE production by 2030.
Galan’s 100-percent-owned Greenbushes South Project is located in Western Australia and boasts advantageous positioning 3 kilometers south of the prolific Greenbushes lithium mine owned by Talison, Tianqi, IGO and Albermarle. Drilling of the first target was completed in July 2023. Galan is currently developing land access agreements for future drilling campaigns at Greenbushes South. An exploration license has been granted to the company for an additional key tenement, E70/4629 targeting lithium-bearing pegmatites for five years to February 2029. The tenement is approximately 260 kilometres south of Perth, the capital of Western Australia, and less than 30 kilometres south of the Greenbushes pegmatite at the Greenbushes Mine.
In 2023, Galan entered into an exclusive binding agreement with Redstone Resources to acquire 100 percent of the Camaro-Taiga-Hellcat property blocks from Infinity Stone Ventures (CSE:GEMS,GEMSF,FSE:B2I). The assets are located in the world-class James Bay Lithium Province in Quebec, collectively covering 5,187 hectares. The joint venture also includes an option to acquire 100 percent of the PAK East and PAK Southeast Lithium Project, spanning 1,415 hectares in Ontario’s Electric Avenue near Frontier Lithium’s PAK Lithium Project.
Galan has a highly experienced management team with over a century of professional expertise in the resource, finance and energy sectors. This results-oriented board and their vested interest in the company's success prime Galan for exceptional discovery potential and advanced development of its high-quality projects.

Key Projects
Hombre Muerto West Project
The 100-percent-owned Hombre Muerto West project is a large land property that sits on the west coast of the Hombre Muerto salar in Argentina, the second-best salar in the world for the production of lithium from brines. The property also leverages strategic positioning adjacent to notable competitors like Livent to the east.
Galan has increased HMW’s mineral resource to 8.6 Mt contained LCE @ 859 mg/L lithium (previously 7.3 Mt LCE @852 mg/L lithium), one of the highest grade resource estimates declared in Argentina. HMW’s measured resource is now at 4.7 Mt contained LCE @ 866mg/L lithium. Inclusion of the Catalina tenure adds ~1.3 Mt LCE to the HMW resource.
The pilot plant at HMW has validated the production of lithium chlorine concentrate, adding reagents to eliminate impurities, and generating a concentrate at 6 percent lithium. The plant comprises pre-concentration ponds, a lime plant, a filter press and concentration ponds.
Pilot Plant at HMW
Construction for Phase I has already commenced for 5.4 ktpa LCE production at HMW, and aims to deliver lithium chloride production in H1 2025. The fourth long-term pumping test (PBRS-03-23) results at HMW record an outstanding lithium mean grade of 981 mg/L - the highest reported grade from a production well in the Hombre Muerto Salar.
In April 2024, Galan announced 33 percent project completion with pond construction at 45 percent and project execution is advancing as planned.
A definitive feasibility study (DFS) for phase 2 shows a 20.85 ktpa LCE operation at HMW, targeting high-quality, 6 percent concentrated lithium chloride product (equivalent to 12.9 percent lithium oxide or 31.9 percent LCE) in 2026. The DFS also indicated phase 2 will deliver a post-tax NPV (8 percent) of US$2 billion, IRR of 43 percent and free cash flow of US$236 million per year. Phase 2 provides an exceptional foundation for significant economic upside in phases 3 and 4, targeting 60 ktpa LCE production by 2030.
The company has signed a binding term sheet with a wholly owned subsidiary of Glencore for offtake of up to 100 percent of its premium lithium chloride concentrate from HMW, and the offer to provide or facilitate a secured financing prepayment facility for US$70 to US$100 million, subject to conditions precedent being met.
Galan is targeting first-phase HMW lithium concentrate production in H1 2025
Galan now has 100 percent full ownership of the Catalina tenement that borders the Catamarca and Salta Provinces in Argentina. The newly secured Catalina tenure has a strong potential to significantly add to the existing HMW resource. The tenure also covers the Catalina, Rana de Sal II, Rana de Sal III, Pucara del Salar, Deseo I and Deceo II tenements.
Greenbushes South Lithium Project
The 100-percent-owned Greenbushes South lithium project is located near Perth, Western Australia, and is three kilometers south of the world-class Greenbushes lithium mine, managed by Talison Lithium. The Greenbushes South tenements can be found along the Donnybrook-Bridgetown Shear Zone geologic structure, which hosts the lithium-bearing pegmatites at the Greenbushes Lithium Mine.
Greenbushes South covers nearly 315 square kilometers, and hosts elevated pathfinder elements with well-defined anomalies adjacent to the property.

DLE Pilot Plant First Stage Production Completed, Downstream Process Optimised with Sample of Battery-Grade Lithium Produced
Highlights:
- An initial volume of 88m3 of concentrated eluate, which is the lithium carbonate equivalent (LCE) of approx. one tonne, has been produced from the Company´s DLE pilot plant in Copiapó, Chile over an operating period of 384 hours with 14 cycles completed
- This completes the first stage of production from the DLE pilot plant
- Results show the DLE adsorbent achieved a lithium recovery rate of approximately 95% from the brine, with total recovery (adsorption plus desorption) achieving approximately 88%
- Impurity rejection rates were very high producing a low impurity eluate conducive to the downstream conversion process.
- The concentrated eluate is being shipped in four batches to the facilities of Conductive Energy in Chicago, USA, for conversion into battery grade lithium carbonate
Shipment | Eluate Volume | Eluate Li Grade | LCE (kg) | Shipment Status |
1 | 24m3 | 2008 mg/L | 257 | Arrived process facility |
2 | 24m3 | 2360 mg/L | 301 | In Shipment |
3 | 24m3 | 2325 mg/L | 297 | In shipment |
4 | 17.5m3 | 2464 mg/L | 230 | At departure port |
Targeted | 90m3 | 2000 mg/L | 1022 | |
Total Achieved | 88m3 | 2289 mg/L | 1085 |
Table 1: Status of concentrated eluate from pilot plant first stage production
- Conductive Energy completed test-work on a 200L sample of concentrated eluate shipped in May 2024 to optimise the downstream process before receiving the larger volume shipments
- The conversion test-work produced multiple samples of lithium carbonate with 99.75% lithium carbonate purity demonstrating that the process achieves targets and is repeatable
- The result is a first confirmation that a process has been developed that will efficiently produce battery-grade lithium for the Laguna Verde project from pilot scale DLE eluate
- CleanTech Lithium continues to be a leader in exploration and development of DLE based projects in Chile and this pilot scale production will provide large test samples of lithium carbonate to potential offtake partners seeking product qualification.
- Subject to the completion of the re-injection well in September, the reserve report for Laguna Verde is scheduled to be completed by Montgomery and Associates in October 2024.
Steve Kesler, Executive Chairman and Interim CEO, of CleanTech Lithium PLC, said:
"We are very pleased by these results as it shows we can produce battery-grade lithium with low impurities from our Laguna Verde brine project. Working with our partners on the downstream process, Forward Water and Conductive Energy, we can now demonstrate the entire DLE process from brine to final lithium product.
"The optimised downstream process will now be applied to the initial volume of 88m3 of concentrated eluate, or approximately 1 tonne of LCE, produced from the first stage of production from our DLE pilot plant. This will produce significant test sample volumes of battery-grade lithium carbonate for commencement of testing with potential strategic partners. This is important whilst the Chilean government is reviewing the feasibility of lithium projects to identify the most advanced companies in Chile and if they are to reach their target of having three to four new lithium projects in development by 2026."
Further Information
Pilot Plant in Copiapó First Stage Production Completed
The Company´s DLE pilot plant is in Copiapó, Chile, approximately 275km from Laguna Verde. The plant finished commissioning in late March 2024 and up until mid-June a total volume of 1196m3 of brine from the Laguna Verde project was processed in the plant with a total of 14 cycles completed. Each cycle represents a volume of brine being fed first through filtration to remove suspended solids, then into DLE columns which are filled with adsorbent designed to be selective for lithium molecules. Lithium, as lithium chloride, is adsorbed from the brine, before desorption with water to create a purified lithium chloride eluate. A reverse osmosis (RO) unit at the DLE pilot plant then concentrates the eluate by extracting approximately 75% of the water to form a concentrated eluate.
Averaged across the 14 cycles, the recovery rate achieved by adsorption of lithium by the adsorbent was 95% and the recovery rate of desorption from the adsorbent was 93%. The total recovery rate averaged 88% and was highly consistent as shown in Figure 1. The temperature of the brine and desorption water, using the average ambient temperature in Copiapó during the March to June period of operation, was in the range of 20oC to 25oC, which did not significantly affect the recovery achieved.
Figure 1: Pilot Plant Total Recovery Rate
The eluate production rate was relatively stable after the initial ramp up period achieving an average of 2.8 kg LCE per hour. The design of the plant is 1 tonne per month of LCE based on designed monthly operating schedule of 360 hours. Due to budget and volume considerations, the plant was run for 384 hours for the first stage of planned operation producing a total of 1.085 tonnes of LCE as eluate. Based on the hourly production rate this met and exceeded the design capacity of the plant.
Figure 2: Pilot Plant Production Rate (Kg LCE/hr in Eluate)
Selectivity of the adsorbent is another key performance parameter for a DLE operation. DLE primarily acts as a purification stage, recovering lithium chloride from the brine whilst rejecting other impurities. For all the major ions in the brine, apart from boron, the rejection rate was very high as shown in Fig. 3 below. More cycles will further validate this performance. The quality of the eluate was consistent over the first stage of production with the low level of impurities facilitating downstream conversion.
Figure 3: DLE Performance - Rejection of Major Impurities
After completion of the DLE stage, the eluate is concentrated using a reverse osmosis (RO) unit at the pilot plant. On completion of both stages the lithium grade in the purified lithium chloride eluate is over ten times higher than the feed brine. The concentrated eluate was then loaded into a flexitank in a standard shipping container and transported to the port of Caldera for shipment to North America.
Downstream Processing into Battery Grade LithiumCarbonate: Test-work Completed
For the conversion of the concentrated lithium chloride eluate into battery grade lithium carbonate, CleanTech Lithium has engaged a leading lithium processing company, Conductive Energy, based in Alberta, Canada, which has facilities in Chicago, USA, with key downstream processing units shown in Figure 4 below. The status of the concentrated eluate shipment is shown in Table 1 with processing to commence in August 2024.

Figure 4: Conductive Energy Carbonation Reactor Tank and Equipment for Washing, Filtering & Drying
In May 2024 CTL air-freighted a 200L sample of concentrated eluate from the pilot plant to Conductive Energy to undertake test-work to optimise the conversion process. The process steps are shown in Figure 5, involving a further stage of RO, before using Forward Osmosis (FO) to achieve a very high level of concentration. Ion exchange (IX) is used to remove calcium, magnesium, and boron. The final steps are carbonation and then washing, filtration and drying to produce a battery grade product. Conductive Energy´s approach is to simplify the process that achieves maximum yield by minimizing process steps and, where losses occur, produce fluids that are easily recycled to further maximize yield.
Figure 5: Conductive Energy Conversion Process
Reverse Osmosis and Forward Osmosis
The increase in eluate and lithium concentration in the R/O and F/O stages are shown in Table 2 below. R/O is effective for concentration until Total Dissolved Solids (TDS) reach the level of approximately 60,000 - 70,000 TDS, after which it is increasingly energy intensive and costly. F/O is highly effective in further concentration to the required lithium grade for carbonation, in this case 18,000mg Li/L (or 1.8% Lithium). The F/O unit is provided by Forward Water Technology, another Canadian company based in Ontario. F/O achieves a high concentration factor with much lower energy use than the alternative of using a mechanical evaporator, while being highly suitable for utilising solar thermal as the energy source to power the F/O process.
Parameter | Unit | Concentrated Eluate | R/O Concentrate | F/O Concentrate |
Lithium (Li) | mg/L | 2,194 | 5,700 | 18,000 |
Chloride (Cl) | mg/L | 11,039 | 37,000 | 110,000 |

Ion Exchange to Remove Impurities
Ion exchange (IX) was used for removal of calcium and magnesium, which achieved 85% and 87% reductions respectively. While feed concentrations were low, 100% of barium and manganese were also removed in the same process. Additional optimization is possible with potential for further calcium removal. Lithium loss was low at 3%.
Conductive then applied its optimised IX for removal of boron. This was highly effective achieving >99.5% removal of boron. However, there was a 22% loss of lithium to the regeneration fluid. This would be recaptured by recycling the regeneration fluid to the F/O feed which was not implemented for this small-scale test-work. The lithium loss from the boron IX is expected to be reduced (recovered) to a steady state loss rate of about 3%.
Carbonation and Battery Grade Lithium Sample
The carbonation test-work achieved an exceptional yield of 96% of the theoretical maximum. The final product, after the wash procedure, was 99.75% lithium carbonate purity as shown in Table 3. Further optimisation of the washing stage is planned in order to reduce impurities to the greatest extent possible and therefore maximise the value of the battery grade product.

Additional Operations
Laguna Verde Reserve Report Update
The next stage of resource evaluation at the Laguna Verde project is to produce an updated JORC compliant resource and a reserve report based on converting a portion of resources into reserves. The management of the resource evaluation programme and reserve report is led by Montgomery and Associates, a leading hydrogeology consultant with extensive experience in resource evaluation of lithium brine projects in Chile and Argentina. Reserve estimation will feed directly into the Pre-Feasibility Study which is targeted for later this year.
The reserve calculation requires the completion of pumping tests and a re-injection well at the project which is scheduled for September 2024, when drilling equipment can be re-mobilised after the current winter break in operations. Subject to the completion of the re-injection well in September, the reserve report is scheduled to be completed by Montgomery and Associates in October 2024.
