In mid-November 2023, Jindalee Lithium Limited (Jindalee, the Company) announced results from beneficiation of composite samples from the Company’s 100% owned McDermitt Lithium Project located in Oregon, USA, and noted that acid leaching of beneficiated samples was underway1.
- Excellent lithium (Li) extraction rates from acid leaching of beneficiated McDermitt ore
- Li extraction from composite samples averaged 93% (250µm) and 94% (75µm)
- Li extraction from all units exceeds 98% with higher acid additions
- Leaching of a bulk sample is underway to enable downstream testwork
- Samples have been shipped to POSCO for parallel leach testwork
Samples of ore were beneficiated with a cut-size of 250-micron (µm). Material passing was either leached directly (“250µm leach feed”) or ground further so that all passed 75µm (“75µm feed”).
Jindalee is pleased to advise that initial results from acid leaching of the beneficiated samples have been received, with extremely high lithium extraction rates recorded from both the 250µm and 75µm leach feeds using 500kg sulphuric acid per tonne of leach feed. The 250µm leach feed was also leached with a higher strength acid (850 kg/t leach feed) and returned exceptional extraction rates (>98.5%) for all units (Table 1).
Table 1 – Maximum Lithium Extraction at variable feed sizes and acid strengths - Units 4, 6, 8 and 10 (* calculated)
The leach testwork extended for up to four hours with most of the Li extraction occurring in the first hour. Optimised lithium extraction and acid addition rates will be incorporated into the Pre-Feasibility Study (PFS).
Leaching of a bulk composite has commenced to provide lithium in solution for downstream testwork. Beneficiated samples (250µm) have also recently been shipped to POSCO Holdings (NYSE: PKX) (POSCO) for testwork, pursuant to the Memorandum of Understanding signed with POSCO in February 20234.
Discussion
In July 2023 Jindalee shipped approximately 700kg of drill core to Hazen (Colorado, USA) for metallurgical testing, with this testwork being managed by global engineering, procurement, construction and maintenance (EPCM) company Fluor Corporation (Fluor). The core samples were selected from Units 4, 6, 8 and 10 within the Indicated portion of conceptual Pit Shell 6 (nominal 43 years); these units carry elevated lithium grades and selective mining of these units has the potential to deliver significantly higher-grade material (when compared to the Mineral Resource Estimate average grade) for processing (Figure 1) (Table 2)2.
Figure 1 – Schematic Section C-C’ with completed drilling, simplified geology and conceptual Pit Shell 6 (nominal 43 years). (Note: lateral projection onto section plane and 3x vertical exaggeration may cause distortion)
Head assays for these samples were announced in October 20233 with Units 4, 6, 8 and 10 averaging 1,790 ppm Li, 34% higher than the average McDermitt Mineral Resource grade (1,340 ppm Li)2. Results from attrition scrubbing (beneficiation) of a composite sample of McDermitt ore (250µm cut-size) were announced mid- November 2023, recording 92.0% Li recovery with 25.3% mass rejection and the lithium grade to leach increasing to 2,107 ppm Li1.
The acid leaching testwork now being reported was conducted on both 250µm and 75µm leach feed sizes using 500 kg/t (and 850 kg/t for 250µm leach feed). A composite sample (representing a nominal life-of-mine average feed) was also tested using the two leach feed sizes, recording very high lithium extraction rates using 500 kg/t. Lithium extraction from the coarser (250µm) leach feed was 92.9% and compares favourably with the extraction rate (94.0%) achieved from the finer (75µm) leach feed (Table 1).
Next Steps
Acid leaching of a bulk composite sample is currently underway to provide lithium in solution for downstream work. Results from this testwork will feed into the PFS which is expected to be completed mid-2024.
Samples from Units 4, 6, 8 and 10 have been beneficiated (250µm) and shipped to POSCO for parallel leach testwork, pursuant to the Memorandum of Understanding signed with POSCO.

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.
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.

Forward Water Technologies
Overview
Forward Water Technologies (TSXV:FWTC) is helping lithium mining companies and other industries reduce their environmental impact through its innovative wastewater treatment technology that enables industrial operations to reduce liquid waste volume by up to 95 percent.
Environmental, social and governance (ESG) ratings continue to be a key business strategy for organizations as they impact public perception and partnership possibilities. For water-intensive industries, such as mining, sustainable wastewater management is critical.
Transformative wastewater technologies are critical for both businesses and the world’s population. In fact, unless sufficient progress is achieved, UNICEF and WHO estimate that 1.6 billion people will be without access to safe drinking water by 2030, and 2.8 billion will be without access to safe sanitation and hygiene. Water treatment technologies can disrupt current trends and improve global access to safe drinking water.
Through its Forward Osmosis (FO) technology, Forward Water is providing an environmentally friendly alternative to traditional wastewater disposal. Traditionally, wastewater disposal requires transporting untreated wastewater for deep well disposal or high-intensity thermal treatment.
Forward Water’s FO system is installed at the client site, and wastewater is treated to reduce waste volume and produce valuable clean water for reuse in the manufacturing process. Then, the significantly reduced volume of wastewater is transported and disposed of, significantly saving on transportation and disposal costs.
The FO technology targets three massive sectors: industrial wastewater, mining and food manufacturing. Forward Water’s unique and patented FO technology achieves high-rate water extraction within a low-energy continuous process. The process reduces waste and allows up to 95 percent water recovery, ready for reuse.
Forward Water’s Li-FO™ technology is ideal for lithium-brine mining operations, allowing mines to “fine tune” brine sources to improve concentration by up to 20 times. This results in improved recovery and makes lower-concentration brines economically viable. Forward Water is currently embarking on an early development testing project to further evaluate and refine the technology’s viability in lithium mining.
In 2023, the company’s wholly owned subsidiary, Forward Water Technologies Inc., licensed specific intellectual property from FUJIFILM Corporation to solidify the protection of its water treatment technology platform.
CleanTech Lithium (AIM:CTL,Frankfurt:T2N,OTC:CTLHF) has contracted FWT to provide advisory services for the support and development of CleanTech Lithium's direct lithium extraction (DLE) process in Chile. The collaboration will use FWT’s industrial forward osmosis system in the hyper-concentrating of CleanTech Lithium's eluate and its conversion into battery-grade lithium carbonate through Conductive Energy's DLE process.
Howie Honeyman, CEO, explained in an interview how the company’s technology can improve lithium mining operations. “A lot of lithium being mined today around the world is coming from underground aquifers that store the lithium brine. The challenge is that the lithium is surrounded by other minerals and salts, requiring chemical ‘tweezers’ to pluck out that lithium. What we can do is, at multiple places in that process, we can concentrate that lithium-containing water stream, which makes it far easier for these miners to handle the volumes they need to extract that lithium.”
An experienced management team with technical expertise leads the company towards further refining and deploying its technology. The team includes experts in materials science, chemistry and engineering. Additional experts in corporate administration and financing round out the leadership team to lead the company toward its goals.
Company Highlights
- Forward Water Technologies has developed a patented wastewater treatment technology that reduces wastewater volume and improves reusability across multiple industries, including mining and food manufacturing.
- The company’s Forward Osmosis (FO) technology disrupts the traditional method of wastewater disposal by reducing the amount of waste that must be transported and disposed of, directly reducing costs.
- The FO technology also improves water reusability by up to 95 percent, reducing the expense of importing water for industrial processes.
- The Forward Water Technologies Li-FO™ process is applicable in the lithium mining sector by improving concentration by up to 20 times, allowing organizations to improve extraction efficiency.
- The company has partnered with a lithium-brine extraction operation to evaluate its Li-FO™ technology.
- Forward Water Technologies is in early negotiations to deliver an FWTC forward osmosis pilot system on-site in Chile to support a customer's lithium extraction process.
- Forward Water Technologies has licensed specific intellectual property from FUJIFILM Corporation to solidify the protection of its water treatment technology platform.
- The company has been contracted by CleanTech Lithium to provide advisory services for the support and development of CleanTech Lithium's direct lithium extraction processes in Chile.
- An experienced management team with a blend of relevant technical expertise leads the company toward refining and marketing its technology.
Key Project
Forward Osmosis Water Treatment
Forward Osmosis is a naturally occurring process in which water is spontaneously drawn across a membrane when one solution is higher in salt concentration than the other. The difference in salinity, known as the osmotic gradient, creates a low-energy water treatment process.
Forward Water Technologies has leveraged the naturally occurring process to innovate its patented, three-step FO technology, enabling a 95 percent wastewater reduction and 95 percent water recovery.
Project Highlights:
- Patented Three-Step Process: Forward Water Technologies FO process achieves low-energy and high-rate water extraction with a unique three-step design:
- Water Extraction: Water is drawn across the FO membrane into a salt draw solution. The combination of the patented draw solution and unique membrane “locks” the draw solution on one side of the membrane, creating a true closed-loop process.
- Water/Salt Separation: Next, a switchable water salt (SWS) achieves water/salt separation as low-grade heat is applied, and it phases from liquid to gas. As the gas leaves the solution, clean water is left behind. The energy necessary for this step is often found in many facilities in the form of waste heat.
- Salt Draw Reconcentration: Finally, as the gas leaves the solution, it is captured within the closed-loop system and is passively cooled, causing it to phase back into liquid form as an SWS. The SWS liquid is collected and recycled back to the front of the membranes in the water extraction step, creating a continuous process.
- Widely Applicable Water Treatment: The low-energy process allows organizations across several industries to improve water reclamation and reduce wastewater by up to 95 percent. Additionally, the process allows for up to 20 times concentration, making the process amenable to lithium-brine extraction and other potential applications.
- Significant Cost Savings: The primary value proposition for the FO process is cost reduction in wastewater transportation and disposal. With the process in place, more water is reclaimed for reuse in manufacturing, which reduces the raw volume of wastewater that must be transported and disposed of.
