Independent verification of high-grade lithium carbonate
from Kachi Demonstration Plant
3 April 2023



Highlights


• Independent testing of lithium carbonate produced from Kachi Lithium Project confirms grades and purity greater than 99.8%

• Saltworks test with independent analysis validates commercial process for Kachi Project and confirms ability to produce high-quality, battery grade lithium carbonate using Lilac's DLE technology

• Product quality exceeds project design specification and battery grade specifications of major South American lithium brine producers


Clean lithium developer Lake Resources NL (ASX:LKE; OTC:LLKKF) in partnership with its DLE technology partner, Lilac Solutions, Inc. (“Lilac”), announces that independent testing of lithium carbonate produced from their joint Kachi Project in Argentina has confirmed grades and purity greater than 99.8%. Project Kachi is a world-class lithium development project that is poised to lead the industry in the production of high-quality lithium with minimal environmental footprint.

This test, performed by Saltworks with independent analysis by two third party labs, validates the major commercial process systems for the Kachi Project and confirms its ability to produce high- quality, battery-grade lithium carbonate from Lake’s brine resource using Lilac DLE technology. The quality of the Li2CO3 product from the Saltworks test exceeds the Project Design Specification and the battery grade specifications of major- South American brine lithium producers.

Context to the Testing

As announced in early January, Lilac successfully operated the Demonstration Plant for over 1,000 hours and produced 40,000 litres of lithium chloride eluate before December 31, 2022, meeting important performance milestones in accordance with the agreed timeline. The lithium chloride eluate produced by Lilac using its propriety ion exchange technology was then shipped to Saltworks, in Canada, and a portion was converted to lithium carbonate, after which it was independently tested for purity.

The Lilac demonstration plant continues to operate, as Lilac nears completion of the performance milestone to process 120,000 litres of eluate for conversion into battery grade lithium carbonate.

“This is a new process that has now been proven to produce high grade lithium in our ‘mining and refining’ facility – this means a critical part of the value adding chain is being captured by Lake,” said Lake CEO David Dickson.

“It also sets a new standard for what it means to be a responsible member of the lithium supply chain.”

“The Lilac team is excited to see these concrete results showing that our technology is not only faster with higher recovery, but also enables a higher purity product,” said Lilac Solutions CEO Dave Snydacker.

“Alongside Lake Resources, we are proving that it is possible to produce lithium – the cornerstone of our clean energy future – without damaging the planet we’re trying to save. I look forward to further development of a clean, socially responsible lithium supply chain, and the continued success of our joint Kachi project.”
