E3 Lithium Limited reported it has completed additional predefined tests at the Direct Lithium Extraction Field Pilot Plant with successful results. As previously outlined, the series of three tests was designed to trial various operating parameters to select the optimal set for an extended operating period. Preliminary internal analysis and results of the additional test are outlined below: Initial lithium recovery: >94%Purity of concentrate: >80% and Average lithium grade in concentrate: 916.6 mg/L. The change in operating parameters across this test was to optimize the cycle time (the amount of time the sorbent was exposed to the brine).

The tests outlined that can decrease the amount of time the brine is in contact with the sorbent. This optimization may lead to a reduction in the capital and operating costs of the commercial plant, which will be outlined in the upcoming Pre-Feasibility Study (PFS). Next Steps: The team has actively analyzed the data received from the pilot operation over the past six weeks and is completing standard due diligence reviews.

Once that work is complete, E3 Lithium will outline the full set of results against the KPIs outlined on June 14, 2023. The Company will use the results of the first three tests to set the conditions for the extended operating period that is expected to begin next week. Upon completion of the longer operating period, E3 Lithium will have the data required for its PFS and Definitive Feasibility (DFS) studies, as well as further engineering that will lead to the construction and operation of its first commercial facility.

This extended operation will also produce lithium concentrate for further downstream processing of battery-grade Lithium Hydroxide Monohydrate (LHM). E3 Lithium Completes the Production of Lithium Hydroxide Monohydrate: E3 Lithium is also pleased to report that it continues to progress its downstream refining test work. The Company has now produced LHM and will share more details in the coming weeks.

Separately, from the exercise of stock options that were or are soon to expire, some insiders plan on selling a portion of their shares to pay for the associated tax liabilities. The insiders continue to remain supportive of the Company and have collectively agreed to sell only the minimum required number of shares to cover tax liability from their exercise and related expenses.
