Lake Resources partners with Lilac Solutions for Technology and Funding to Develop the Kachi Lithium Brine Project in Argentina

  • Under the agreement, Lilac Solutions will contribute technology, engineering teams, and an on-site demonstration plant, earning in to a maximum 25 percent stake in Lake’s Kachi project based on performance; Lilac will be expected to fund its pro rata share of future development costs, currently estimated to be approximately US$50 million – aligning innovation, funding, development, and production.
  • The Lilac production process is lower cost and offers higher lithium recovery rates (80-90 percent) than other technologies to produce battery quality lithium carbonate (99.97 percent purity), while also protecting the local environment, including water resources.
  • Follows the recent successful sourcing of an Expression of Interest from the Export Credit Agency of the United Kingdom to provide project finance for the first stage of the Kachi Project; Expression of Interest to cover approximately 70 percent of the total finance required to expand production to 50,000 tpa of high purity lithium carbonate equivalent.

Lake Resources NL (ASX: LKE; OTC:LLKKF) and Lilac Solutions, Inc. are pleased to announce that after extensive successful test-work, they have entered into a partnership for technology and funding to develop Lake’s Kachi Lithium Brine Project in Argentina; under the terms of the partnership earn-in, Lilac is able to achieve an equity stake in the project with certain corresponding project funding obligations, while providing its leading technology to advance the project.

“We have progressed methodically through testing and pilot stage work and are now pleased to have the partnership established,” Lake’s Managing Director, Steve Promnitz said.

“Lilac’s technology is truly disruptive as it has taken a non-mining tech solution which cuts operating costs and boosts lithium recovery from our brines. The process is modular producing high purity lithium and can be ramped up quickly through pilot to commercial stages – this equity stake ensures a rapid commercialization of the Lilac technology at the Kachi site.”

Mr. Promnitz said end users of high purity battery materials were demanding more environmentally friendly production methods and Lilac’s innovative and efficient direct extraction method sets the new industry standard.

Lilac’s Chief Executive Officer, Dave Snydacker, said the Kachi project is a globally significant lithium resource.

“With the Lilac technology we can efficiently deliver the large volumes of high-quality lithium chemicals needed by battery makers.

“Importantly, this will be done in a way that is environmentally-friendly. We’ve worked extensively with this brine, generating the data needed for engineering studies, and it is a fantastic fit for the Lilac technology.

“We’re thrilled to be partnering with Lake, and the Lilac team is excited to demonstrate our technology on site at Kachi and advance the project,” Mr Snydacker said.

Lake Resources Chairman, Stu Crow, said: “With a successful capital raising; partnering with a leader in lithium processing that will place us in the bottom quartile on the cost curve; and getting an Expression of Interest for debt funding from the UK’s Export Credit Agency – it has been a busy few months for Lake.

“We have all worked hard to align Lilac’s industry leading technology and our project funding in order to accelerate development and production of the resource.”

“We are closing the gap to being fully funded when you assume the DFS and other requirements for UKEF are met. There aren’t many near term lithium projects that can say they are funded to production.”

He said recent research on the lithium market from Macquarie and J.P. Morgan has been encouraging, with Macquarie forecasting that the lithium market is now likely in a perpetual deficit while J.P. Morgan said supply will struggle to keep up with demand, with a perpetual deficit visible beyond 2030 until more projects are defined by the industry.

Mr. Crow said he was also encouraged by developments on the ground in Argentina.

“The words ESG means one thing to investors, but to our people on the ground and local communities in Catamarca Province, the Lilac processing technology means a much more efficient use of limited water resources, better recovery rates, and less impact on the land surface.”

“We’ll also be adding renewable power to the project as part of the DFS.”

Mr. Crow said all levels of the Argentinean Government were doing their best to encourage lithium development and the advancement of local communities, but governments were relying on companies like Lake and Lilac to make the technical innovations that would benefit the local environment and communities.

About Lake Resources NL (ASX:LKE OTC:LLKKF) – Clean high purity lithium using efficient disruptive clean technology – in demand by EV makers and lithium-ion batteries

Lake Resources NL (ASX:LKE, OTC: LLKKF) is a clean lithium developer utilising direct extraction technology for production of sustainable, high purity lithium from its flagship Kachi Project in Catamarca Province within the Lithium Triangle in Argentina among other projects covering 200,000 ha.

This direct extraction method delivers a solution for two rising demands of electric vehicle batteries – high purity battery materials to avoid performance issues, and more sustainable, responsibly sourced materials.

  1. Clean-Tech: Efficient, disruptive, cost-competitive technology using well-known water treatment re-engineered for lithium (not mining). Technology partner, Lilac Solutions Inc, supported by Bill Gates led Breakthrough Energy fund and MIT’s The Engine fund.
  2. High Purity: 9.97% purity lithium carbonate samples for a premium price. Demonstrated high quality in NMC622 lithium-ion batteries (refer ASX announcement 20 October 2020; 2 March 2021).
  3. Sustainable /ESG: Far smaller environmental footprint than conventional methods, that returns virtually all water (brine) to its source with a low CO2 footprint.
  4. Prime Location, Large Projects: Flagship Kachi project in prime location among low-cost producers with a large lease holding (70,000 ha) and expandable resource (4.4 Mt LCE) of which only 20% is used for 25 years production at 25,500tpa (JORC Resource: Indicated 1.0Mt, inferred 3.4Mt, refer ASX announcement 27 November 2018). Pre-feasibility study by tier 1 engineering firm shows large, long-life low-cost operation with US$1.6 billion NPV pretax, and annual EBITDA of US$260 million from 2024 (refer ASX announcement 17 March 2021; 28 April 2020,).

An innovative direct extraction technique, based on a well-used ion exchange water treatment method, has been tested for over 18 months in partnership with Lilac Solutions, with a pilot plant module in California operating on Kachi brines and has shown 80-90% recoveries. Battery quality lithium carbonate (99.97% purity) has been produced from Kachi brine samples with very low impurities (refer ASX announcement 20 October 2020). The first samples of high purity (99.97% purity) battery quality lithium carbonate were tested in a NMC622 battery by Novonix with excellent results (2 March 2021).

This method of producing high purity lithium can revolutionise and disrupt the battery materials supply industry as it’s scalable, low cost, and delivers a consistent product quality.

Lake’s other projects include the Olaroz and Cauchari brine projects, located adjacent to major world class brine projects in production or construction, including Orocobre’s Olaroz lithium production and adjoins the impending production of Ganfeng Lithium/Lithium Americas’ Cauchari project. Lake’s Cauchari project has shown lithium brines over 506m interval with high grades averaging 493 mg/L lithium (117-460m) with up to 540 mg/L lithium. These results are similar to lithium brines in adjoining leases and infer an extension and continuity of these brines into Lake’s leases (refer ASX announcements 12 June 2019, 23 March 2021).
