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)
