Yes that is correct Lilac provided some samples on LKE's Kachi Project. I have provided an extract for your perusal.

• Phase 1 Engineering Study shows potential for lithium production costs to be US$2,600/tonne (+/-30%) in lowest quartile at Lake Resources’s 100% owned Kachi Lithium Brine Project in Argentina, using Lilac’s direct extraction process.
• High lithium recoveries of 85-90% confirmed from multiple brine samples, with lithium concentrations greater than 25,000 mg/L produced from ~300 mg/L lithium brine.
• On-site pilot plant eyed in 2019 as part of pre-feasibility study (PFS), as a precursor to full-scale commercial project offering rapid, low-cost production with low environmental impact.
