The McDermitt Lithium Project Pre-Feasibility Study (PFS) – released in November 2024 – has outlined a 63-year project producing lithium carbonate from a chemical conversion facility built adjacent to one of America’s largest lithium resources
Investment Highlights
- 100%-owned world class deposit positioned 35km from Thacker Pass, the most advanced lithium project currently under development in the USA
- PFS demonstrates a highly profitable, low-opex, multi-decade project with a 5-year capital payback
- Large-scale project with outstanding metallurgical properties and is amenable to bulk mining methods
- McDermitt is advantaged by US policies designed to develop domestic critical mineral supply chain

McDermitt Lithium Project
Oregon / Nevada
The McDermitt Lithium Project is situated at the northern end of the McDermitt Caldera—a mineral-rich geological formation that hosts one of the world’s largest known accumulations of lithium mineralisation.
McDermitt contains a JORC-compliant Mineral Resource of 21.5 Mt lithium carbonate equivalent (LCE), including a maiden Probable Ore Reserve of 2.34 Mt LCE, underpinning a 63-year project life and highlighting the scale and longevity of the Project. The Project lies approximately 35km north of Lithium Americas’ Thacker Pass Project, which is currently under development with backing from General Motors and a low-interest loan from the U.S. Department of Energy.
Amid growing bipartisan focus on domestic supply chains, current U.S. policy settings continue to prioritise critical minerals and reduce reliance on imports. In 2025, McDermitt was designated a FAST-41 “Transparency Project,” recognising its national strategic importance and unlocking an expedited federal permitting pathway.
Jindalee is committed to unlocking the full potential of McDermitt by:
- Progressing key permitting milestones to enable future development;
- Advancing discussions with strategic partners and relevant U.S. government departments to explore funding and co-investment opportunities;
- Continuing metallurgical testwork to optimise the process flowsheet, with a focus on reducing costs and assessing potential coproducts;
- Laying the groundwork for and commencing a Feasibility Study; and
- Engaging with local communities and stakeholders in Oregon and Nevada, with a strong commitment to environmental stewardship, transparent engagement, and responsible project desig

Clayton North Project
Nevada
The Clayton North Project is located 23 km north of Silver Peak, currently the only producing lithium operation in the US. Extensive areas of lithium bearing claystones outcrop within the claims area, and initial drilling has returned intercepts of 6.1m @ 1093ppm Li and 11.2m @ 1006ppm Li from shallow depths. Further exploratory drilling is planned to follow up the encouraging results from our initial drill program.
