Jindalee Resources Limited (to be renamed “Jindalee Lithium Limited”) (Jindalee, the Company) announced an updated Mineral Resource Estimate (MRE) at Jindalee’s 100% owned McDermitt Lithium Project (US) (Figure 1)1.
- Exploration Target confirms excellent potential for further resource growth
- The Exploration Target is in addition to the Mineral Resource Estimate announced February 20231
- Anomalous lithium assays from surface sampling highlight further potential at McDermitt
The 2023 MRE for McDermitt contains a combined Indicated and Inferred Mineral Resource Inventory of 3.0 Billion tonnes at 1,340ppm Li for a total of 21.5 Million tonnes Lithium Carbonate Equivalent (LCE) at 1,000 ppm cut-off grade. At 21.5 Mt LCE, McDermitt is the largest lithium deposit in the US by contained lithium in Mineral Resource, and a globally significant resource (Table 3), with the deposit remaining open to the west and south (Figure 1).
Jindalee is also pleased to announce an independently estimated Exploration Target Range (ETR) at McDermitt. The ETR of 300 – 700 Million tonnes at 1,100 – 1,400ppm Li (at 1,000ppm Li cut-off) is extrapolated from drilling completed at the Project (Table 1, Figure 1).
Table 1 – Summary of Exploration Target Range at cut-off of 1000ppm. LCE calculated using the midpoint of the range.
Recent relogging of McDermitt drilling, combined with regional mapping and sampling, has recognised up to 12 distinctive and laterally continuous stratigraphic units which can be tracked across the Project area. The Exploration Target surrounds and abuts the 2023 MRE and is extrapolated from 62 holes drilled at McDermitt from 2018 to 2022. Material for the MRE extends to a maximum distance of 1,200m from the nearest hole, with the ETR extending to a maximum of 1,500m from the nearest hole (Figure 1).
In August 2022 Jindalee submitted an Exploration Plan of Operations (EPO) to the Bureau of Land Management (BLM), with the EPO deemed complete by the BLM in May 20232. Once approved, the EPO will allow Jindalee to significantly increase on-site activity, including up to 160 holes designed to both infill the 2023 MRE and test areas currently covered by the Exploration Target. Jindalee expects the EPO to be approved 2H 2024, with drilling to commence soon after.
Furthermore, sampling of weathered sediments exposed in drainages west and south of the Mineral Resource and Exploration Target areas has returned strongly anomalous lithium values, indicating excellent potential to locate additional lithium mineralisation in these areas (Figure 1, Table 2).
Figure 1 – Plan view of the McDermitt Lithium Project with 2023 Mineral Resource1 (at 1523mRL), completed drilling, Exploration Target and Surface Sampling locations outside the Mineral Resource and Exploration Target areas.
Methodology
The methodology used for the ETR was identical to that used for the 2023 MRE1. A total of 62 drillholes and 97 density measurements were used for the estimation of both the 2023 MRE and the ETR, with lithium estimated by Ordinary Kriging. The block size for estimation was 200mE by 200mN by 5mRL, with sub-celling permitted to 40mE by 40mN by 1mRL.
The ETR estimates were guided by stratigraphy, which is the major control on the continuity of both lithium grade and geology, with material for the ETR limited to within 1,500m of the nearest hole. The entire mineralisation inventory (2023 MRE and ETR) occurs within 215m of surface.
A summary of all drill data included in both the 2023 MRE and the ETR is included in Annexure A. All other details pertaining to the reporting of exploration results and the 2023 MRE and the ETR are detailed in Annexure B.

Drilling Targets Defined – Bananal Valley tenement, Lithium Valley, Brazil
Highlights
Work Undertaken
- Assays received from 100 and 200 metre spaced soil sampling lines with soil samples taken at 50 metre intervals.
- Lithium anomalies identified over the 1.5 km strike extent of the soil grid with coincident Be, Rb, Sn and Tl anomalies.
- No lithium anomalies found in areas of laterite however tin anomalies as well as quartz and tourmaline occurrences suggest pegmatite extensions under the laterite.
- Drill holes defined so environmental permits can be obtained to allow drilling to take place.
Future Workplan
- Obtain environmental permits for drilling
- Extra soil lines in the NW of tenement to follow up anomalies previously defined
- Continue detailed mapping to refine currently identified pegmatite trends
- Drilling of the lithium targets identified.
Details
Results from exceptionally high value stream sediment sample have been followed up with soil samples and grid based mapping in the southern part of 831.700/2022 and drilling targets had been identified.
Mapping prior to and during soil sampling identifies numerous small pegmatites and some larger pegmatites to a maximum of 10 metres wide. Areas of large quartz boulders, possibly quartz cores to pegmatites, were also mapped and in places are coincident with lithium and lithium pathfinder anomalies. Pegmatites cross cut and are younger than the foliation in the host G3 type granite.
Regional structure from geophysics and from topography shows a strong NE to ENE trend, subparallel to the Latin Resources “Lithium Corridor.” Drilling will be oriented at 90 degrees to the regional trend initially, as the most probable major pegmatite orientation direction.
Strong vertical zonation in the lithium pegmatite geochemical responses are present and close attention to the location of laterite and the old lateritised surface is critical to interpretation of where lithium pegmatites may be concealed by leaching of lithium.
Drill targets were defined by lithium anomalies and by occurrences of pegmatite or extensive float of pegmatite minerals, lithium pathfinder elements, large quartz boulders or anomalous quartz concentrations.
The lateritic weathering zone is estimated from mapping to be up to 50 metres thick within the tenement, but locally may be significantly thicker. Drilling below this weathered layer is essential to get analyses that reflect the actual grade of any pegmatites present. Within the weathering zone low values of lithium are expected from potentially economic pegmatites.

This region contains two producing mines, the undeveloped Colina deposit, and several prospects with significant exploration activity. While close proximity does not guarantee similar results it does provide evidence to assist in targeted exploration.
Mapping and soil sampling in the western Bananal Valley tenement, 831.700/2022, has defined areas of laterite as well as various larger pegmatite and quartz occurrences.
Figure 2 shows the extensive high order stream sediment target zones in the Bananal valley tenement, with their follow up soil lines and potential pegmatite mineral occurrences, including green tourmaline, indicating highly evolved pegmatites.

Who is Gina Rinehart?
Gina Rinehart is an Australian iron ore magnate and the executive chair of Hancock Prospecting, as well as the richest person in Australia and one of the world’s richest women. Rinehart is the daughter of Australian mining mogul and Hancock Prospecting founder, the late Lang Hancock. As the current executive chair of Hancock Prospecting, Rinehart won the inaugural Lifetime Achievement Award from CEO Magazine in 2019.
Rinehart was appointed as an Officer of the Order of Australia in 2022 for her “distinguished service to the mining sector, to the community through philanthropic initiatives, and to sport as a patron.”
How did Gina Rinehart get rich?
Gina Rinehart inherited Hancock Prospecting after her father’s passing in 1992. The following year, Gina Rinehart’s company acquired the Roy Hill tenements. Centering the massive project as the cornerstone of the company, Hancock Prospecting has greatly benefited from the iron ore market boom that began in the early 2000s.
Today, Roy Hill is Australia’s largest iron ore mine, producing 60 million tonnes of iron ore per year. The mine was recently approved to increase its annual production to 70 million tonnes. Success at Roy Hill has made Hancock Prospecting Australia’s most valuable private company, worth an estimated AU$15.6 billion.
As with many of the world’s most successful billionaires, Gina Rinehart has developed an investment strategy based on strategic partnerships as well as diversification to mitigate risk and build value. Under her leadership, Hancock Prospecting Pty Limited (HPPL) as well as the HPPL Group of companies has expanded into some of the world’s most economically important markets, such as real estate, agriculture, energy and critical metals.
For the 2024 fiscal year, Rinehart's Hancock Prospecting reported a bumper profit of AU$5.6 billion, up 10 percent from the previous year.
What mining companies does Gina Rinehart own?
Through her company Hancock Prospecting, Gina Rinehart owns interest in mining companies across many sectors, including iron ore, lithium, rare earths, copper, oil and gas, as well as potash. While much of her investment portfolio is focused on Australia and ASX companies, Rinehart is actively strengthening the geographical diversification of her investments.
In recent years, Rinehart has made a series of key investments in mining companies, especially targeting critical metals projects in Germany, Brazil, Ecuador and the United States. These include exploration-stage firms such as Titan Minerals (ASX:TTM) and Azure Minerals as well as producers such as Atlas Iron and MP Materials.
Where does Hancock Prospecting mine iron?

Hancock Prospecting’s Roy Hill and Hope Downs iron ore mines are located in the resource rich Pilbara region of Western Australia.
Roy Hill has attracted strategic partnerships with major global enterprises: Marubeni (TSE:8002) with a 15 percent equity stake; POSCO (NYSE:PKX,KRX:005490) holds a 12.5 percent stake; and China Steel (TPE:2002) has a 2.5 percent equity position. The minority partners purchase a combined 28.75 million tonnes of iron ore annually from Roy Hill’s production.
In September 2024, Hancock Prospecting got the green light for its AU$600 million McPhee iron mine located about 100 kilometres north of the Roy Hill mine after a long approval process. The McPhee iron mine is expected to produce around 10 million tonnes of the metal each year over an estimated 15 year mine life. First production is expected to kick off next year, and ore will be transported by road trains to Roy Hill for processing and blending. The goal is to improve the larger mine's product mix and sustain its production volumes.
The Hope Downs iron ore complex is another of Australia’s largest iron ore projects. A 50/50 joint venture partnership with Rio Tinto (ASX:RIO,NYSE:RIO,LSE:RIO), Hope Downs hosts four open-pit mines and has an annual production capacity of 47 million tonnes. Hope Downs has also been the subject of a more than decade-long civil dispute in a Western Australian court over royalties, put forth by the descendants of Lang Hancock's business partner Peter Wright as well as Rinehart’s own children.
Gina Rinehart’s iron ore investments
Gina Rinehart’s iron ore investments in Western Australia extend beyond Roy Hill and Hill Downs to its subsidiary Atlas Iron’s three producing mines and a pipeline of development projects, as well as an earn-in agreement on Legacy Iron Ore (ASX:LCY) and Hawthorn Resources’ (ASX:HAW) Mt Bevan project through its subsidiary Hancock Magnetite Holdings.
Rinehart’s Hancock Prospecting acquired Atlas Iron in 2018 through a AU$427 million deal that turned out to be dirt cheap as the company would go on to deliver AU$1.5 billion in revenues over the next three years alone.
Today, Atlas Mines operates the Mt Webber, Sanjiv Ridge and Miralga Creek mines. Production from these mines in its fiscal year ended June 2023 led to a AU$222 million dividend payment for Rinehart’s Hancock Prospecting.
At Mt Bevan, as part of its earn-in agreement, Hancock completed a prefeasibility study (PFS) for a 12 million tonne per year high-grade magnetite project in July of 2024. The PFS incorporated a mineral resource estimate totalling 1,291 million tonnes, which was completed by Atlas, and delineates a capital cost of AU$5 billion to develop the potential Mt Bevan mine.
Completion of the PFS increased Hancock’s stake in the JV ownership from 30 percent to 51 percent with Legacy now holding 29.4 percent and Hawthorn 19.6 percent.
Like iron, coal is another essential material in steel manufacturing. To this end, Rinehart is also pursuing an investment in a past-producing metallurgical coal mine in Alberta, Canada. Hancock Prospecting subsidiary Northback Holdings is the owner of the proposed Grassy Mountain steelmaking coal project in the province’s Crowsnest Pass region. Northback is awaiting approval of its exploration licenses for the project.
Gina Rinehart’s lithium investments
Gina Rinehart's lithium investments include Azure Minerals’ (ASX:AZS) Andover lithium project, Liontown Resources, Delta Lithium (ASX:DLI) and Vulcan Energy Resources (ASX:VUL). The majority of her lithium investments have came in a flurry over the past year.
In June 2023, Rinehart’s Hancock Prospecting signed a separate joint venture earn-in agreement for the Mt Bevan magnetite project, which is discussed above, this time for the lithium, nickel and copper mineralization at the project. The agreement will similarly see Hancock able to earn a 51 percent interest by completing certain milestones.
Last September, Rinehart made headlines when she took a position in Liontown Resources and then rapidly increased the position to 19.9 percent over the following month. This allowed Hancock, which was now Liontown's largest shareholder, to effectively block Albemarle’s (NYSE:ALB) accepted takeover of the smaller lithium company.
However, since then, Liontown’s stock has taken a hit as the economics for its near-production Kathleen Valley lithium project in Western Australia have been damaged by the effects of high inflation and low lithium prices. Ultimately, in January, Albemarle decided to sell off its 4 percent stake in Liontown Resources. The lack of any further moves or comment by Rinehart in relation to Liontown Resources has led to speculation she may be waiting for the right opportunity to buy up the lithium company at a discount.
Kathleen Valley entered production in late July 2024, and is expected to produce approximately 2.8 million tonnes per year of spodumene concentrate by the end of FY 2027.
That wasn't the only lithium bid Rinehart blocked in October 2023. As is her strategy, Rinehart scooped up an 18.9 percent stake in Azure Minerals last year after SQM announced its intention for a total takeover of the company and its Andover lithium project in the West Pilbara region of Western Australia. This story had a different ending, though, as Hancock Prospecting instead joined the lithium giant in a AU$1.7 billion deal to become a co-owner of the exploration-stage Andover project, which also hosts nickel, copper and cobalt mineralisation. The deal closed in May 2024.
Shortly after its Liontown and Azure moves last year, Hancock Prospecting continued investing in Western Australia's lithium prospects when it participated in a AU$70.2 million fundraising for Delta Lithium in November 2023. The proceeds of the fundraising will help Delta Lithium to fund the development of its Mt Ida lithium-gold project, which is adjacent to Hancock's Mt Bevan joint venture project. As of November 2024, Hancock Prospecting owns 10.65 percent of Delta Lithium.
Rinehart has made lithium investments outside of Australia as well. Looking further afield to Germany, with a 7.5 percent stake, Hancock Prospecting is the second largest shareholder in Vulcan Energy and its flagship Zero Carbon lithium project in Germany’s Upper Rhine Valley, a milestone Rinehart's company reached after investing an additional AU$20 million in Vulcan, which made headlines in June. The Zero Carbon project is slated to produce an initial 24,000 tonnes of lithium hydroxide by the end of 2025, targeting Europe’s electric vehicle manufacturing sector.
In November 2024, Vulcan Energy reached another major milestone with first production at its downstream lithium hydroxide optimisation plant, which is designed to produce lithium hydroxide and battery-grade lithium hydroxide monohydrate.
Gina Rinehart’s rare earths investments

Through Hancock Prospecting, Gina Rinehart has recently made investments in some of the world’s most well known rare earths producing companies — US-based MP Materials and Australia’s Lynas Rare Earths — as well as development-stage Arafura Rare Earths and exploration-stage Brazilian Rare Earths (ASX:BRE). Rinehart taking a position in these rare earths companies shows she is looking to capitalise on the significant need for these critical metals outside of China.
As mentioned in the introduction to this article, Rinehart’s Hancock Prospecting is the largest shareholder of Arafura Rare Earths, giving it a 10 percent stake in the advanced-stage Nolans project in the Northern Territory. Rinehart made the investment in December 2022.
In April of 2024, Rinehart made two significant moves into the sector. The first came on April 9, when it was revealed that Hancock Prospecting had acquired a 5.3 percent stake in MP Materials, the second largest rare earths producer outside of China. The company’s California-based Mountain Pass mine is the only integrated rare earth mining and processing operation in North America.
Rinehart’s investment in MP Materials could later bring in “Roy Hill-type cash flow,” Dylan Kelly, head analyst at Terra Capital, told Australian Financial Review. “Anything that is producing and not China-aligned is highly strategic. These materials are very, very hard to make and there’s a lot of demand in making magnets for electric vehicles and wind turbines."
One week later, Rinehart’s Hancock Prospecting also took up a 5.82 percent interest in Lynas Rare Earths, the largest ex-China rare earths producer. The Australian rare earths miner produces the critical metals at its Mount Weld mine in Western Australia and ships the raw material to Malaysia for processing. Lynas is also ramping up processing at its Kalgoorlie rare earth processing facility in Australia, and building light rare earths processing facilities and a heavy rare earths separation facility in Texas, US.
Rinehart’s near simultaneous investments in both Lynas and MP Materials comes after merger talks between the two rare earths behemoths stalled in February. There is speculation stirring that Rinehart’s participation could renew merger discussions, Reuters reported. In November, the mining mogul increased her position in MP Materials to 8.5 percent, further raising the possibility of a merger down the road.
Andy Forster, Lynas investor and senior investor of Argo Investments, had his interest piqued by Rinehart’s move "given she's clearly made a play across the whole space. She obviously wants to potentially have a seat at the table if there's any chance of consolidation."
Rinehart is also getting her foot in the rare earths door at the exploration level. In 2023, Rinehart’s Hancock Prospecting made a pre-IPO investment for a 5.85 percent share in Brazilian Rare Earths, which went on to list on the ASX in December of that year. The rare earths explorer is working its district-scale Rocha da Rocha rare earth province in the state of Bahia, Brazil. The province is highly prospective for both heavy and light rare earths, with grades of over 40 percent total rare earth oxides found. Brazilian Rare Earths is working to complete an updated JORC mineral resource estimate.
Gina Rinehart’s copper investments
Gina Rinehart’s copper investments are centered on Ecuador’s Andean copper-gold belt, and include explorer Titan Minerals and Ecuador's state-owned Empresa Nacional Minera (ENAMI).
Ecuador has seen a rush of major mining companies taking up positions in key copper and gold projects in recent years, placing Hancock Prospecting in the company of Barrick Gold (TSX:ABX,NYSE:GOLD), Zijin Mining (HKEX:2899) and Anglo American (LSE:AAL,OTCQX:AAUKF).
Rinehart’s Ecuadorian copper investments are in line with her shift toward the critical metals necessary for the green transition and her strategy to expand the global footprint of her mining empire.
Hancock Prospecting subsidiary Hanrine Ecuadorian Exploration and Mining has been in the region since 2017, but recently began making more investments. In March 2024, Hancock Prospecting subsidiary Hanrine Ecuadorian Exploration and Mining acquired a 49 percent stake in six mining concessions for AU$186.4 million. The deal sees it partner with state mining company ENAMI for the concessions, which surround the stalled Llurimagua copper-molybdenum project in Northern Ecuador.
In late April, Ecuador’s constitutional court nixed appeals by ENAMI and its partner in the Llurimagua project, Chile’s state-owned CODELCO, to review the March 2023 decision by Imbabura’s provincial supreme court suspending the environmental license for Llurimagua.
Shortly after the investment with ENAMI, Rinehart's Hanrine made another play in Ecuador by striking an earn-in agreement with Titan Minerals for up to an 80 percent ownership stake in the explorer’s Linderos copper-gold project contingent on up to AU$120 million in exploration spending. Linderos is an early-exploration stage project with the potential to host a large-scale copper porphyry system. Hanrine has made an initial investment of AU$2 million for a 5 percent stake.
Gina Rinehart’s oil and gas investments
Gina Rinehart’s oil and gas investments include private firms Warrego Energy in Western Australia and Senex Energy in Queensland.
In February 2023, Hancock Prospecting won a protracted bidding war for the then-public Warrego with Warrego's joint venture partner Strike Energy (ASX:STX) for a price of AU$0.36 per share. Warrego and operator Strike Energy maintain their 50/50 joint venture on the West Erregulla onshore gas field within exploration permit EP 469 near Perth in Western Australia.
In mid-August 2024, the West Erregulla project received its production licence and the partners expect to start operations once a final investment decision is made later this year. During phase one, the project is expected to produce 87 terajoules per day.
As for Senex Energy, it is a joint venture between POSCO (50.1 percent) and Hancock Prospecting subsidiary Hancock Energy (49.9 percent) that holds the Atlas and Roma North natural gas developments in Queensland’s Surat Basin. The two JV partners acquired Senex in 2022, with Rinehart’s company putting up AU$440.89 million.
Senex Energy is embarking on a AU$1 billion expansion endeavor at Atlas and Roma North this year that will see 60 petajoules of natural gas delivered to Australia’s east coast market annually by the end of 2025. This figure represents more than 10 percent of the region’s demand. Regulatory approval for the expansion was finally approved following an uphill battle with a Federal government more keen on renewable energy projects than the natural gas variety. Hancock Prospecting reported the first flows of gas production from the expansion field in late November 2024.
Rinehart once had a significant stake of nearly 20 percent in Lakes Oil, now Lakes Blue Energy (ASX:LKO), through subsidiary Timeview Enterprises. Timeview's stake in Lakes Blue Energy has been lowered in recent years, but it remains the company's fourth largest shareholder at 4.63 percent.
In late October, Rinehart offered financial assistance to Mineral Resources (ASX:MIN,OTC Pink:MALRF), a diversified mining company with lithium, iron ore and oil and gas operations in Western Australia. Headed by another mining heavyweight, Chris Ellison, Mineral Resources, or MinRes, is reportedly drowning in debt and embroiled in a tax evasion investigation. At that time, Hancock Prospecting agreed to a AU$1.13 billion buyout of MinRes' oil and gas projects in the Perth Basin and an exploration acreage in the Carnarvon Basin.
The 100 percent sale of two of MinRes' exploration permits to Hancock was completed in December for initial consideration of AU$780 million, with potential for up to AU$327 million depending on whether certain conditions and thresholds are met. The permits include the Moriarty Deep prospect and the Lockyer gas and Erregulla oil discoveries.
Separate to that sale, the two companies are also forming two 50/50 exploration joint ventures for MinRes' remaining permits in the Perth and Carnarvon Basins. Hancock will acquire 50 percent of the MinRes Explorer drill rig, which is the largest in Australia.
Gina Rinehart’s potash and agriculture investments
Gina Rinehart’s potash and agricultural investments center on Hancock Prospecting’s ownership interests in multiple premium cattle stations in Australia, and the company's royalty revenue generated from the Anglo-American-controlled Woodsmith potash project currently under construction in the United Kingdom.
With an original investment of AU$380.6 million in 2016 to then-owner Sirius Minerals, Hancock Prospecting has a 5 percent revenue royalty on the first 13 million tonnes of fertiliser produced from Woodsmith and 1 percent thereafter. Hancock also has a 20,000 tonne-a-year offtake option. The timeline for Rinehart’s royalty revenue has been pushed back, however, as Anglo is cutting spending at Woodsmith following BHP’s (ASX:BHP,NYSE:BHP,LSE:BHP) failed mega-merger with Anglo American.
Investor takeaway
With Gina Rinehart at the helm of Hancock Prospecting, the Roy Hill iron ore mine has generated stellar revenues. That wealth creation not only made her Australia's richest person, but has also built a powerful war chest from which Rinehart is expanding her mining empire.
Investors can take cues from her recent and future moves in the mining sector. Although she may be defensive toward renewable energy technologies encroaching on agricultural land, she understands the strategical importance of investing in critical metals for the green transition such as lithium, rare earths and copper.

Pilot Plant Downstream Process Produces Lithium Carbonate with 99.78% Purity
CleanTech Lithium PLC (AIM: CTL, Frankfurt: T2N), an exploration and development company advancing sustainable lithium projects in Chile, further to "Pilot-Scale Lithium Carbonate Production" RNS on 21 November 2024, announces the production of a high purity lithium carbonate sample from the Company´s pilot plant downstream process.
The Company has also made the decision to voluntarily delist from the OTCQX market in the U.S. The Board did not see the value from low trading volumes and the associated administration costs. The Company's Ordinary Shares continue to trade on the London AIM Market, the Frankfurt Stock Exchange and the U.S. OTC Pink Market.
Highlights:
- The Company is processing concentrated eluate from its DLE pilot plant in Copiapó, Chile at the facilities of Conductive Energy ("Conductive") in Chicago, USA with the aim of producing battery grade lithium carbonate.
- The downstream process design aims to minimise process steps and demonstrate a process that is scalable and can consistently produce a battery-grade lithium carbonate product. Key stages are:
- Eluate concentration using Forward Osmosis ("iFO") to produce a highly concentrated pre-carbonation solution with low energy input
- Treatment of the pre-carbonation solution to remove contaminants
- Carbonation to technical-grade lithium carbonate
- Post-carbonation polishing to achieve battery-grade lithium carbonate
- A substantial volume of pre-carbonation solution and lithium carbonate was produced as reported to the market on 21 November 2024.
- Due to the onset of freezing weather in Chicago from late November, steps were taken to mitigate damage to sensitive iFO processing equipment and iFO concentration was paused.
- Further downstream processing continued using the already produced pre-carbonation solution to refine and analyse the downstream process and lithium carbonate product.
- A test run volume of pre-carbonation solution was processed in December into an 8kg sample of high grade lithium carbonate which a laboratory at the University of Calgary has recently confirmed achieved 99.78% purity.
- This exceeds the 99.6% purity standard (Chinese GB/T 23853-2022 (Type 1) for battery grade lithium carbonate from brine. However, certain individual impurity concentrations were higher than the standard.
- The treatment process was shown to be effective at removing contaminants, resulting in high-quality feed to the carbonation stage.
- The most problematic contaminants in the pre-carbonation solution, Calcium, Magnesium and Boron, were reduced by 98.5%, 99.9% and to non-detection (>99.99%) respectively.
- Conductive Energy is is currently assessing best options to restart iFO operations that are paused due to winter conditions.
- Conductive is utilising the current pause to upgrade the system based on initial data as well as add an nanofiltration step to remove divalent ions (Calcium, Magnesium) before the ion exchange steps which will improve purification efficiency further whilst improvements in automation and process control will be made.
Steve Kesler, Executive Chairman, CleanTech Lithium said: "We are pleased to report the production of high grade lithium carbonate with a purity of 99.78% from an initial batch of concentrated eluate from our Laguna Verde project. This phase of work has focused on fine-tuning the process and preparing to scale up pilot plant output. Our collaborative efforts with Conductive Energy and Forward Water on the downstream process are advancing our aim to produce signifigant quantities of battery grade product to introduce to potential strategic partners and off-takers."

In 2H 2024, a total of 88m3 of concentrated eluate produced at the Company´s DLE pilot plant located in Copiapó, Chile, was shipped to the facilities of Conductive Energy in Chicago, USA, for conversion into lithium carbonate. Processing commenced in November 2024 and a total of 27.5m3 of concentrated eluate was processed through the iFO stage which reduced the volume to 5.3m3 of pre-carbonation solution with lithium concentrations up to 14,400mg/l. The iFO unit is a mobile demonstration scale unit with a feed flow rate of 800 - 1,000L per hour and is an outdoor installation and therefore susceptible to weather conditions. A portion of the solution was processed into approximately 50kg of lithium carbonate as announced to the market on 21 November 2024.

Despite challenging weather conditions in late November, with temperatures in Chicago dropping below zero degrees Celsius, process evaluation continued with the aim of achieving iterative improvements in yield at lower energy and reagent inputs, which helps assess scalability and operating costs.
Adverse weather did pose risks to sensitive process equipment, such as the membrane modules of the iFO unit and further iFO concentration was paused. Under commercial-scale operations, such systems would be housed within temperature-controlled facilities to mitigate these challenges.
Production of High Purity Product
Downstream processing continued using iFO concentrate already produced to run the final purification, carbonation and polishing stages and produce a test quantity of high grade lithium carbonate. The solution produced by the iFO unit was 14,350mg/l Li, a 6.5X increase in concentration of the concentrated eluate. This was achieved without optimisation and in sub-optimal weather conditions. Optimization is expected to achieve a minimum 10X increase in concentration at this stage. Further stages of contaminant removal, carbonation and polishing achieved a high grade lithium carbonate product with a purity of 99.78% Li2CO3

Treatment to Remove Impurities
The purification stage consists of 3 process units - microfiltration, divalent ion exchange and boron ion exchange. These were shown to greatly reduce the concentrated contaminants in the pre-carbonation solution resulting in a high-quality feed to the carbonation process. The most problematic contaminants in the pre-carbonation solution, Calcium, Magnesium and Boron were reduced by 98.5%, 99.9% and to non-detection (>99.99%), respectively. Table 2 shows the major ions in each process stage. Upgrades to the system, including the addition of a nanofiltration step is being implemented to more efficiently remove divalent ions which were at a higher concentration in the concentrated eluate received (although within Lanshen design specification) than the Conductive pilot plant was set up for.

Carbonation Stage
Carbonation proceeded as designed, with initial technical grade material produced from the feed in under 15 minutes of reactor time. The technical grade product was subsequently polished in a single wash step to produce a high-purity lithium carbonate product. Table 2 presents all the detected elements by ICP, undertaken by a laboratory at the University of Calgary, as a percent weight of the total dry product (100% dry mass). Moisture in the product prior to kiln drying was low at 28% wt. The final product achieved 99.78% lithium carbonate purity on a fully dry basis (Table 3).

A comparison to Chinese standard GB/T 23853-2022 (Type 1) for battery grade lithium carbonate is shown in Table 3. Potassium, sodium and chloride will be reduced through changes in carbonation reactor operation such that post-carbonation washing is more effective. The divalent ions, calcium and magnesium, will be reduced following introduction of the nanofiltration step.

Argentina’s Lithium Resource Holds Potential to Power the Global Energy Transition
The significance of Argentina's lithium resources is underscored by recent industry movements. For instance, Rio Tinto's (ASX:RIO,NYSE:RIO,LSE:RIO) $6.7 billion planned acquisition of Arcadium Lithium (NYSE:ALTM,ASX:LTM) highlights the growing interest in brine projects and the strategic value of their location within the Lithium Triangle.
This move signals a broader trend of major players recognising the potential of Argentina's lithium deposits.
The Lithium Triangle: A geological profile
The Lithium Triangle, aptly named for its abundance of the lightweight metal, is the world's largest source of lithium. This region holds the key to meeting the surging demand for lithium-ion batteries that power EVs and store renewable energy. Argentina, with its vast salt flats, is particularly well-positioned to capitalise on this demand.
This region’s extensive salt flats are the result of ancient lakes that have evaporated over millions of years. These salars are underlain by vast aquifers containing lithium-rich brines, formed through the weathering of lithium-bearing rocks. The concentration of lithium in these brines is exceptionally high, with some areas reporting concentrations up to 1,500 milligrams per litre (mg/L), significantly higher than deposits found elsewhere. This unique geological formation, coupled with the arid climate that promotes natural evaporation, creates ideal conditions for lithium extraction.
The geological stability of the region, marked by minimal tectonic activity, further enhances its attractiveness for long-term mining operations. These factors combine to make Argentina's lithium resources not only abundant but also economically viable and strategically accessible for extraction.
Argentina's lithium production primarily relies on brine extraction, a method that offers several advantages over traditional hard rock mining. This process involves pumping lithium-rich brine from underground reservoirs and allowing it to evaporate in large ponds, leaving behind concentrated lithium compounds.
The benefits of brine extraction include:
- Lower production costs compared to hard rock mining
- Reduced environmental impact due to less intensive mining operations
- Higher-grade lithium with fewer impurities, ideal for battery production
These factors contribute to Argentina's competitive edge in the global lithium market, making its projects particularly attractive to investors and battery manufacturers alike.
Spotlight on excellence: Hombre Muerto West project
A prime example of Argentina's lithium potential is Galan Lithium's (ASX:GLN) Hombre Muerto West (HMW) project. Located in the heart of Argentina's lithium-rich Salar del Hombre Muerto, this project exemplifies the high-grade, low-impurity brine that makes Argentine lithium so valuable.
Key features of the HMW project include:
- High-grade lithium brine with concentrations of 859 mg/L
- Low levels of impurities, reducing processing costs
- Strategic location near established operations like Livent Corporation's El Fenix site
- A substantial resource of approximately 8.6 million tonnes of lithium carbonate equivalent
The project's proximity to existing operations enhances its value proposition, potentially allowing for shared infrastructure and knowledge transfer. This strategic positioning within the Lithium Triangle underscores the importance of location in the lithium industry.
Wood Mackenzie’s emissions benchmarking service has also placed HMW within the first quartile of the industry greenhouse gas emissions curve, making the project a globally significant, long-term source of lithium.
Argentina's commitment to lithium production
Recognising the immense potential of its lithium resources, Argentina has taken significant steps to foster growth in its lithium industry. The government has implemented a supportive regulatory framework aimed at attracting investment and accelerating project development.
Key initiatives include:
- A $7 billion investment plan to boost lithium production
- Projected export growth from $1.7 billion in 2022 to $5 billion by 2025
- Streamlined permitting processes for lithium projects
- Incentives for companies investing in lithium extraction and processing
These efforts are expected to significantly increase Argentina's lithium output, solidifying its position as a major player in the global supply chain.
Investment potential
The combination of high-grade resources, favorable extraction methods and supportive government policies makes Argentina's lithium projects highly attractive to investors. Companies like Galan Lithium, with their focus on high-grade brine assets, are well-positioned to capitalise on the growing demand for lithium in the clean energy sector.
Key factors driving investment interest in Argentina’s lithium sector include:
- Lower production costs compared to hard rock lithium mining
- High-quality lithium suitable for high-performance batteries
- Increasing global demand for lithium, driven by EV adoption and renewable energy storage
- Argentina's commitment to expanding its lithium industry
As the world transitions towards cleaner energy sources, the importance of securing a stable lithium supply becomes paramount. Argentina's lithium projects offer a compelling opportunity for investors looking to participate in this global shift.
Investor takeaway
Argentina's strategic position in the Lithium Triangle makes it a crucial player in the global lithium supply chain.
With its high-grade brine resources, favorable extraction methods and supportive government policies, the country is poised to significantly impact the future of clean energy technologies.
As projects like Galan Lithium's HMW continue to develop, and as global demand for lithium surges, Argentina's strategic importance in the lithium market is set to grow. For investors, policymakers and industry stakeholders, keeping a close eye on developments in Argentina's lithium sector will be crucial in navigating the evolving landscape of the global energy transition.
