Next Generation DLE Provider Electralith Produces 99.9% Pure Battery-Grade Lithium Hydroxide from Mandrake Brine
Highlights
- Rio Tinto-backed Direct Lithium Extraction (DLE) and Refining company ElectraLith has successfully produced 99.9% pure battery-grade Lithium Hydroxide from Mandrake’s 100%-owned Utah Lithium Project using it’s cutting-edge DLE-R process
- Requiring no water or chemicals, ElectraLith’s Direct Lithium Extraction and Refining (DLE-R) process has greatly enhanced the potential of the Utah Lithium Project
- The production of battery-grade Lithium Hydroxide direct from brine revolutionises DLE by skipping the conventional interim step of producing lithium carbonate using costly, carbon intensive converters
- Mandrake and ElectraLith progressing a Strategic Partnership Agreement to facilitate the construction of a DLE-R pilot facility at the Utah Lithium Project
Figure 1: DLE-R - Production of Lithium Hydroxide directly from Utah Lithium Project brine
ElectraLith's DLE and Refining (DLE-R) technology processed brines in parallel from both Mandrake’s Utah Lithium Project and Rio Tinto’s globally significant Rincon lithium brine project in Argentina.
Spun out of Monash University and backed by Rio Tinto and IP Group Australia, ElectraLith’s DLE-R is emerging as one of the cleanest, fastest, most versatile and cost-efficient methods of extracting and refining lithium. It’s proprietary electro-membrane technology requires no water or chemicals and can run entirely on renewable power, making it ideal for the water and resource constrained Paradox Basin.
Mandrake sent ElectraLith brines from the Lisbon B-912 well - one of the lower lithium concentration bulk samples from sampling activities undertaken in December 2023. The Lisbon B-912 brines contained 65.6mg/L lithium whilst the Big Indian #1 well (bulk sample sent to DLE provider Electroflow – results expected shortly) brines contained lithium concentrations of 147mg/L. Please see Mandrake’s ASX release of 22 January 2024 and Table 1 attached for further details.
ElectraLith’s work represents the groundbreaking production of Lithium Hydroxide direct from Mandrake’s Utah Lithium Project brines. It also confirms DLE-R’s ability to do so without consuming water or chemicals, greatly enhancing the potential of the Utah Lithium Project.
The ability of ElectraLith’s DLE-R technology to produce battery grade Lithium Hydroxide directly from brine revolutionises DLE by completely circumventing the conventional interim steps of lithium processing, being the production of lithium chloride and lithium carbonate, which often involves the use of costly, carbon intensive converters.
The relationship between ElectraLith and Mandrake is non-exclusive, enabling Mandrake to continue exploring and assessing other competing DLE technologies. To that end, Mandrake is currently awaiting test results from bulk brine samples sent to the Bill Gates-backed US- based DLE company Electroflow (see ASX release dated 22 December 2023).

Managing Director James Allchurch commented:
‘DLE technology is absolutely critical to the future of lithium and the broader global energy transition. Our research into this innovative technology has been comprehensive, quickly identifying ElectraLith as one of the leaders in the field. The ability for ElectraLith’s DLE-R to produce Lithium Hydroxide directly from brine using limited power, no water and no chemicals is revolutionary in the DLE space, putting Mandrake’s US-based brine asset in a commanding position.
I look forward to concluding a partnership agreement with ElectraLith which will facilitate the construction of a DLE-R facility at Mandrake’s Utah Lithium Project.
Furthermore, the maiden Mineral Resource Estimate for the Utalh Lithium Project is well advanced, and I look forward to updating the market when complete.’

Pursuit Minerals: Tier 1 Lithium Play in the Prolific Lithium Triangle in Argentina
Pursuit Minerals Ltd. (ASX:PUR), a top-tier lithium exploration and development company focuses on its flagship Rio Grande Sur lithium project in the Salta Province of Argentina. Rio Grande Sur lithium project is located in an area known as the Lithium Triangle which hosts 50 percent of the global lithium resources and 40 percent of the current global lithium production.
Rio Grande Sur lithium project spans an area of 9,260 hectares on the Rio Grande Salar and is adjacent to several operating lithium mines and development operations, including Acradium Lithium’s Fenix lithium mine and the Olaroz lithium mine.

Recently, the company announced the first phase of operations of its 250 tons per annum (tpa) pilot plant to produce lithium carbonate. The plant will generate both technical and battery grade lithium carbonate at a purity of 99.95 percent, employing a conventional evaporation process.
Company Highlights
- Pursuit Minerals is an ASX-listed company focused on advancing a pre-production lithium brine operation in Argentina.
- The company’s flagship Rio Grande Sur project covers 9,233 hectares on the Rio Grande Salar, in the Salta Province of Argentina located in the Lithium Triangle. The region is home to 50 percent of global lithium resources and 40 percent of world production.
- The acreage owned by Pursuit is situated within an Ni 43-101 inferred resource of 2.1 million metric tons of lithium carbonate equivalent (LCE), with an average grade of 370 milligrams per litre (mg/L) extending to a depth of 100 metres.
- Pursuit delivered a maiden JORC Inferred Mineral Resource Estimate (MRE) of 251.3 kt LCE at 351 mg/L at the Rio Grande Sur Project. With its current Stage 1 drilling program currently underway, Pursuit is targeting a material resource upgrade in the second quarter of 2024, which will build on the recent inferred maiden resource.
- The company has commenced the first phase of operations to produce lithium carbonate at its recently commissioned pilot plant, which is expected to achieve an operational capacity of 250 tons per annum (tpa). This is a significant milestone in the journey to advance toward the first production at Rio Grande Sur.
- Despite temporary fluctuations in lithium carbonate prices, the market continues to demonstrate resilience, with long-term projections indicating a significant 225 percent surge to reach 2.6 million tons of LCE worldwide by 2030.
