Jindalee Lithium
Overview
Jindalee Lithium (ASX:JLL,OTCQX:JNDAF) is an Australia-based exploration and development company advancing North America’s largest lithium deposit. After a spinout of its Australian assets, Jindalee has become a pure-play lithium company focused exclusively on its promising 100-percent-owned McDermitt project. Jindalee recognises the vast opportunity for lithium projects in the US as the country progresses towards its sustainable energy transition and developing a robust domestic supply chain for critical minerals.
As the US strives to transition to clean energy, demand for lithium will continue to increase as this critical mineral is necessary to achieve the country’s net-zero goals. With its favorable mining policies and infrastructure, the US actively supports the advancement of new projects to strengthen its domestic supply chain.
Jindalee’s McDermitt asset, located in southeast Oregon, contains a unique type of lithium mineralisation. Most lithium projects in North America are lithium brine or pegmatite deposits; however, the McDermitt project is an unconventional sediment-hosted lithium asset.
Sediment-hosted lithium deposits such as McDermitt are long-life assets with low strip ratios and low mining costs. Jindalee can leverage this advantage over other lithium assets, both in terms of reaching production faster and reducing operating expenses.
There is currently no commercially operating sediment-hosted lithium project in North America. Two recently announced projects, however, are under development and demonstrate McDermitt’s future trajectory as both companies move toward production.
The 2023 mineral resources estimate (MRE) for McDermitt 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 million tons (Mt) 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, with the deposit remaining open to the west and south.
In June 2023, Jindalee commenced a pre-feasibility study (PFS) on the McDermitt Lithium Project appointing Fluor Corporation as lead engineer. The company expects completion of the PFS by mid-2024. Jindalee also announced initial metallurgical results from acid leaching of the beneficiated samples of McDermitt ore. Lithium extraction from composite samples averaged 93 percent (250 micron (µm)) and 94 percent (75 µm) while lithium extraction from all units exceeded 98 percent with higher acid additions.
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 spearhead the DOE's Critical Materials Innovation Hub
An experienced management team, with the right blend of experience and expertise in geology, corporate administration and international finance, leads Jindalee to fully capitalise on the potential of its assets.
Company Highlights
- Jindalee Lithium is a pure-play lithium exploration and development company focusing on its flagship McDermitt lithium project, currently the largest lithium deposit in North America.
- The United States has ambitious electrification goals but lacks the critical minerals to reach them. Jindalee aims to strengthen the North American supply chain to enable the country to reach net-zero emissions targets.
- Globally, most of the lithium is currently sourced from either pegmatite or lithium brine deposits. The company’s McDermitt deposit, however, is sediment-hosted, an emerging style of lithium deposit with the potential to be a long-life, low-cost source of lithium.
- There are presently no sediment-hosted lithium assets in North America that have reached production. Jindalee is ideally positioned to help fill this void in the market.
- Other companies in North America are moving towards production, and their progress indicates Jindalee’s future trajectory.
- An experienced management team leads Jindalee towards capitalising on the potential of its assets.
Key Project
McDermitt Lithium Project
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. Following positive results from its 2022 drill campaign, the resource at McDermitt has increased to 21.5 Mt LCE, making McDermitt the largest lithium deposit in North America.
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.
- Resource Increased by 62 percent 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. The updated resource released by the company contains a combined indicated and inferred total of 21.5 Mt LCE at 1,000 ppm cut-off grade.
- Memorandum of Understanding (MOU) with POSCO Holdings: Jindalee entered into an MOU with POSCO Holdings (NYSE:PKX), under which POSCO will fund metallurgical testwork on McDermitt ore and undertake joint research for the asset. POSCO is partnering with General Motors to supply cathode active material (including lithium) for its electric vehicles.
- 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.
- Highly encouraging metallurgical testwork: Results from beneficiation and acid leaching tests have exceeded expectations. Beneficiation testwork completed in late 2023 (on sample representing a nominal life-of-mine average feed) recovered 92 percent of the lithium to leach feed and rejected 25.3 percent of the mass at a cut size of 250 µm. Additionally the acid leach test work announced in early 2024 demonstrated very high lithium extraction rates on beneficiated ore. Specifically, the calculated lithium extraction for a composite sample using 250 µm leach feed was 92.9 percent which compares favourably with the extraction rate (94 percent) achieved through testwork from the finer (75 µm) leach feed using 500 kg/t acid. Further testwork is now underway.
- PFS in progress: Jindalee has appointed Fluor Corporation to commence the PFS for McDermitt, set to be completed by mid-2024.

Spodumene Pegmatite Discovery at Esperança Project in Brazil Yields LIBS Results up to 4.04% Li2O
The discovery has been made during early-stage exploration programs which include project scale geological mapping, ground reconnaissance, and soil sampling. These early-stage programs remain ongoing with further results to come over the coming weeks. The discovery supports the Company’s exploration thesis and uplifts the remaining prospectivity across all three project areas: Canabrava, Caraíbas and Esperança projects.
HIGHLIGHTS
- Artisanal excavations reveal a lithium bearing pegmatite with elongate crystalline spodumene crystals up to 50cm in length
- LIBS (Laser Induced Breakdown Spectroscopy) results of spodumene crystals return up to 18,800 ppm Lithium, or 4.04% Li2O
- Discovery provides walk up drill target for fully funded drilling campaign to begin Q1 2025
- Soil sampling and geological mapping continues across the Esperança, Canabrava and Caraíbas projects with further results due over the coming weeks
Lightning Minerals Managing Director Alex Biggs said, “I am highly encouraged by these results from Brazil. As I have spoken about, as a team we are committed to discovery and completing our works in a diligent and structured manner, the proof of which is in these results. The Company is progressing its projects in Brazil quickly and cost effectively and generating significant results for the business which we feel will be transformational. I am proud of and congratulate our geology teams both in Australia and Brazil who have conducted themselves in a professional and astute manner which has been crucial in making a discovery such as this. This is a great first step for us in Brazil and is testament to the prospectivity of the region as I have discussed previously. We look forward to drilling in Q1 2025 and further results to come imminently from all three project areas in Brazil. I would also like to thank our shareholders who have supported our vision and exploration strategy. As a Company we are firmly committed to the lithium thematic and firmly committed to Brazil where we see significant potential moving forwards”.
Lithium Discovery at Esperança Project
During geological mapping fieldwork conducted in mid-November 2024 field geologists encountered a previously unknown historical artisanal mine within the Esperança project area. The site presented with a small access which opened into a set of sub vertical shafts sunk several meters into schists of the Salinas formation. Upon investigation the geology team has discovered pegmatitic lithologies in the walls of the excavations, of which the suite of minerals indicates inclusion of macro crystalline (up to 50cm) elongate crystals of spodumene as shown in Figure 1(a) and Figure 1(b).
Figure 1a (left): Brazilian geologist Vitor Araujo Alves showing the spodumene rich portion of the zoned pegmatite discovered at the Esperança Property. Figure 1b (right): Large elongate spodumene crystals (Spd) up to 50cm in length showing homogeneous growth patterns amongst a quartz (Qtz) and Feldspar (Fdsp) rich matrix
The Company’s geologists have collected selective mineral specimen grab samples in sample VLM207 (Figure 2). Six separate minerals have been analysed via a SciAps Z-903 hand-held LIBS (Laser-Induced Breakdown Spectroscopy) device which has returned lithium endowment of up to 18,800 ppm lithium, which equates to a lithium oxide percentage of 4.04% Li2O.
The SciAps Z-903 handheld LIBS device is considered a qualitative analysis technique only and is used as an in-field preliminary check to establish if a mineral is lithium-bearing. Certified laboratory assays are required to provide accurate, quantitative analysis. A table of the six SciAps Z-903 handheld LIBS results testing the spodumene crystals is shown in Table 1. A full table of results are presented in Appendix 2, Table 2.
While the current field observations indicate that the mineral identified is a lithium-bearing mineral, the percentage of lithium produced from the LIBS analyser does not correlate to an accurate quantitative measurement of the lithium concentration of the mineral itself, or to the overall grade of the pegmatite.
