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)

Beneficiation Delivers 4,480ppm Lithium Clay Concentrate at Red Mountain Project, USA
Latest results reinforce ability to upgrade Red Mountain mineralisation
Astute Metals NL (ASX: ASE) (“ASE”, “Astute” or “the Company”) is pleased to report further positive results from the latest phase of beneficiation testwork for its 100%-owned Red Mountain Lithium Project in Nevada, USA. The results continue to strengthen the Project’s commercial development potential.
Key Highlights
- Follow-up Falcon C beneficiation testwork completed on diamond drill core samples from the Red Mountain Project.
- Sample upgraded from 3,245ppm to 4,481ppm Lithium.
- Successful removal of 51.8% of dense material and concurrent 38% increase in lithium grade.
- Reinforces the April 2025 results indicating that Red Mountain mineralisation may be upgraded using beneficiation.
- Attrition Scrubbing beneficiation testwork now underway for comparison with the Falcon testwork results.
- Leaching testwork to be undertaken on Falcon and Attrition Scrubbing products to confirm reduced acid consumptions.
Following on from the results announced on 22 April 2025, this second phase of Falcon Beneficiation testwork was designed to concentrate lithium-bearing clay and remove unmineralized gangue (waste) in order to decrease mass and increase lithium grade. In a mineral processing context, a reduction in tonnes and volume processed with an increased head-grade typically results in lower processing costs.
This second Falcon testwork program was conducted by Sepro Laboratories (Sepro) and utilised high- clay drill core samples from hole RMDD002 (which intersected 86.9m @ 1,470ppm Li from 18.3m4). This follow-up test was designed to establish how high-clay material performed using the Falcon method, for comparison with results from the previous test conducted on lower grade mineralisation from Red Mountain.
The latest result indicates a strong ability to upgrade mineralisation, achieving a reduction of sample mass by 51.8% with a concurrent increase in lithium grade of 38% (from 3,245 to 4,481ppm Li), with an overall 66.6% lithium recovery. These results compare favourably with the previous round of testwork, exhibiting both a greater upgrade in lithium and reduction in mass, with a substantial 43% reduction in calcium and carbon (interpreted as calcite removal) expected to result in a significant reduction in acid consumption. The Company has commissioned Attrition Scrubbing testwork – another method of beneficiation – for comparison with the Falcon results. Once complete, sample products from both the Falcon and Attrition Scrubbing tests will be assessed for acid consumption in future leachability tests.
Astute Chairman, Tony Leibowitz, said:“The demonstration of a commercial pathway to a lithium product is the natural complement to the establishment of a Mineral Resource. It is for this reason that Astute has actively advanced workflows for both exploration drilling and metallurgical testing at Red Mountain, in tandem. These positive results, which reinforce the previous results from the project, represent the systematic de-risking of what continues to emerge as an important US- based critical metals project.”
Figure 1. Clay-rich RMDD002 drill-core from 160-165ft (3,280ppm Li) used in Falcon beneficiation testwork.
Background
Located in central-eastern Nevada (Figure 4), adjacent to the Grand Army of the Republic Highway (Route 6), which links the regional mining towns of Ely and Tonopah, the Red Mountain Project was staked by Astute in August 2023.
The Project area has broad mapped tertiary lacustrine (lake) sedimentary rocks known locally as the Horse Camp Formation1. Elsewhere in the state of Nevada, equivalent rocks host large lithium deposits (see Figure 4) such as Lithium Americas’ (NYSE: LAC) 62.1Mt LCE Thacker Pass Project2 and American Lithium (TSX.V: LI) 9.79Mt LCE TLC Lithium Project3.
Astute has completed substantial surface sampling campaigns at Red Mountain, which indicate widespread lithium anomalism in soils (Figure 3) and confirmed lithium mineralisation in bedrock with some exceptional grades of up to 4,150ppm Li1,5.
A total of 19 RC and diamond drill holes have been drilled at the project to date for a combined 3,666m. Exploration drilling has been highly successful, with strong lithium mineralisation intersected in every hole for which assays have been received9.
Scoping leachability testwork on mineralised material from Red Mountain indicates high leachability of lithium of up to 98%, varying with temperature, acid strength and leaching duration, and proof-of- concept beneficiation testwork has indicated the potential to upgrade the Red Mountain mineralisation6,8.
About Beneficiation
The primary purpose of beneficiation is to optimise the value of mineralised material by separating unwanted waste material (gangue) from valuable minerals.
Testwork conducted to date at Red Mountain indicates that clay-hosted lithium mineralisation may be upgraded through beneficiation, which seeks to remove coarser grained material, such as particles of sand, that do not contain appreciable lithium8. Successful beneficiation can result in reduced reagent consumption, reduced plant wear and tear, and a reduced environmental footprint.

Pursuit Dispatchs 99.5% Lithium Carbonate Samples to Potential Strategic Partners as Feasibility Studies Progress
Pursuit Minerals Ltd (ASX: PUR) (“PUR”, “Pursuit” or the “Company”) is pleased to announce that high- purity lithium carbonate samples have been dispatched to multiple parties as part of its engagement with prospective offtake and strategic partners. The samples were produced from the Company’s 250tpa Pilot Plant in Salta, Argentina, using synthetic brine chemically identical to that of the Rio Grande Sur Lithium Project.
HIGHLIGHTS
- Final product assays confirm 99.5% lithium carbonate purity, upgraded from pilot output via bench scale processing.
- Certified samples dispatched to multiple potential offtake and strategic partners for qualification.
- Feasibility study progressing for low cost, 5,000tpa operation at Rio Grande Sur.
- Ongoing small batch lithium carbonate production to support offtake qualification while preserving capital discipline in current market conditions.
- Pursuit continues to advance its dual-pronged growth strategy progressing Rio Grande Sur while accelerating the evaluation of strategic gold, silver, and copper acquisitions in Argentina.
Figure 1 – Pursuit’s 99.5% Li₂CO₃ Sample Ready for Dispatch to Potential Offtake Partners
In relation to the dispatch of samples, Pursuit Managing Director & CEO, Aaron Revelle, said:
“Achieving 99.5% lithium carbonate purity is a major technical milestone for Pursuit and a clear demonstration of the capability embedded within our flowsheet, team, and pilot plant infrastructure. It not only validates the compatibility of our process design with Rio Grande Sur brines but also confirms our ability to deliver a consistently high-quality product suited to a wide range of industrial and energy storage applications. Dispatching these samples to potential offtake partners is a critical first step in our commercialisation pathway, enabling product qualification and accelerating engagement with strategic customers in tough market conditions. As we transition into the next phase of development, our focus is firmly on advancing feasibility for our 5,000tpa operation and securing long-term partnerships that will underpin the future production and growth of the Rio Grande Sur Project.”
Initial pilot production at Pursuit’s 250tpa Pilot Plant in Salta successfully produced 15 kilograms of lithium carbonate at 98.9% purity, validating both the compatibility of the Rio Grande Sur brine and the efficiency of the Company’s conventional processing flowsheet. To enhance product quality and simulate potential refinement steps at commercial scale, a portion of this material was further treated at bench scale using fractional crystallisation (FX) and ion exchange (IX) techniques. These post processing steps upgraded the product to 99.5% purity, meeting established benchmarks for technical-grade lithium carbonate.
The final product assays confirm not only the effectiveness of Pursuit’s downstream purification strategy but also the scalability and robustness of its broader flowsheet. This achievement represents a critical milestone on the path to commercial readiness supporting key feasibility assumptions, validating end product quality, and enabling active engagement with prospective offtake partners.
Pursuit is well positioned to undertake additional small-batch production as required to meet partner qualification needs and advance strategic discussions. Furthermore, it demonstrates Pursuit’s capability to produce high-purity lithium carbonate suitable for industrial use, with potential to meet battery-grade specifications through additional refinement.

Ore Reserve Quadruples for Rhyolite Ridge Project; Reaffirms Robust Project Economics
Ioneer Ltd (ASX: INR, Nasdaq: IONR) (Ioneer) is pleased to announce a 308% upgrade to the Ore Reserve estimate for its 100%-owned Rhyolite Ridge Lithium-Boron Project (‘Rhyolite Ridge’ or the ‘Project’) in Nevada, USA, alongside updated Project economics.
- Rhyolite Ridge Ore Reserve more than quadrupled from 60 million tonnes in 2020 to 247 million tonnes, delivering a mine life of 95 years
- Ore Reserve now contains a total of 1.92 Mt of lithium carbonate equivalent and 7.68 Mt of boric acid equivalent
- Underpinning plans for a large, long-life, low-cost expandable operation, producing lithium carbonate, boric acid and then battery-grade lithium hydroxide
- Stable co-product - boric acid accounts for an average 25% of annual revenue in the first 25 years; helping ensure positive EBITDA at low lithium prices and EBITDA margin of 65.7% based on average production over first 25 years
- All-in sustaining cash cost of US$5,745 per metric tonne lithium carbonate equivalent places the Rhyolite Ridge Project in the bottom of the global lithium cost curve
- Compelling Project economics with an after-tax NPV of US$1.367 billion, and an unlevered, after-tax internal rate of return (IRR) of 14.5%
The Ore Reserve has increased by 186.6 million tonnes (Mt) and approximately 48% of the Mineral Resource has been converted into Reserve, now estimated at:
- 246.6 Mt at 1,464 ppm lithium and 5,444 ppm boron
- Containing 1.92 Mt of Lithium Carbonate Equivalent (LCE) and 7.68 Mt of Boric Acid Equivalent (BAE)
“Today’s updated Reserve and Mine Plan reinforces the importance of Rhyolite Ridge’s remarkable mineralogy. Our Ore Reserve estimate of 247 Mt containing a total of 1.92 Mt LCE and 7.68 Mt BAE make it the largest lithium-boron Reserve in the world,” said Bernard Rowe, Managing Director, Ioneer. “It allows Ioneer to match prevailing market conditions and blend or prioritise ore to produce a valuable boric acid co- product, whose market is uncorrelated with the Project’s primary lithium product. No other lithium project offers this level of flexibility and economic advantage. In periods of low cycle lithium pricing, like today, we plan to prioritize the high-boron ore production to optimize the relative proportion of total revenue derived from boric acid.”
By prioritising High-Boron (Hi-B) ore in the first 25 years of production, the Project is poised to produce an average of ~19,200 tonnes per annum (tpa) of LCE, and 116,400 tpa of boric acid (see Table 1).
The updated Ore Reserve estimate, 95-year mine plan for stage one operations, and Project economics reaffirms Rhyolite Ridge as a highly attractive global Project to produce lithium carbonate, lithium hydroxide and boric acid. The updated findings position Ioneer, on an LCE basis, in the lowest cost quartile for lithium production globally with an estimated all-in sustaining cash cost to produce battery grade lithium hydroxide of US$5,745 and a cash cost of C1 $3,858 per tonne net of expected boric acid revenue in the first 25 years.
The Project has a stable overall operating cost structure to produce lithium carbonate and battery grade lithium hydroxide due to the scale and reliability of its boric acid credit. Boron remains one of the most stable natural resource commodities over many decades.
Ioneer has refined Project plans over the past four years and updates now include an Association for the Advancement of Cost Engineering (AACE) Class 2 capital cost estimate (-10%, +15%) with approximately 70% of the Project’s engineering complete. As a result of this and other engineering work including RAM analysis and detailed engineering design, Ioneer has adopted a more conservative approach to plant availability, equipment downtime and maintenance strategies. While this approach reduces bottom line economics, the Company believes it is appropriate for a Project of this type and scale.
The Company now estimates total capital expenditure to complete the Project will be US$1,667.9 million, including a 10% contingency.

Lithium Africa’s mission is to discover, de-risk, and monetize Tier 1 hard rock lithium assets through data-driven targeting, aggressive fieldwork, and disciplined exit strategies. Its partnership with Ganfeng—one of the world’s leading lithium producers—anchors its strategy with industrial expertise and financial strength from the earliest phases of project development.
Lithium Africa is the first company to implement a systematic, multi-jurisdictional discovery strategy across the continent, combining world-class geology with capital discipline and strategic focus to unlock the next generation of globally significant lithium deposits.
Company Highlights
- Exploration-focused Model: Lithium Africa focuses purely on discovery and value creation, with no intention to develop or operate a mine
- Strategic 50/50 JV with Ganfeng Lithium: Doubles exploration spending and provides access to processing expertise and long-term downstream offtake partners.
- Pan-African Footprint: Over 8,000 sq km of tenure across Zimbabwe, Morocco, Mali, Côte d’Ivoire, Guinea, and others – enabling diversification in discovery strategy.
- Contrarian, Countercyclical M&A: Well-capitalized and positioned to roll up distressed lithium juniors during a downcycle
- Rapid Permitting & Scalability: Target jurisdictions offer 3- to 4-year discovery-to-mine timelines versus 10 to 15 years in North America.
- RTO & Listing Expected by August 2025: Tight structure, early institutional support and significant near-term drilling catalysts
