E3 Lithium Outlines the Performance of its DLE Pilot Against KPIs

CALGARY, ALBERTA, November 7, 2023 – E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), “E3

Lithium” or the “Company”, Alberta’s leading lithium developer and extraction technology innovator, is

pleased to report it has completed field testing of its proprietary Direct Lithium Extraction (DLE) technology

at its pilot plant. E3 Lithium provides an overview of the results below, which have met and exceeded its Key

Performance Indicators (KPIs).

E3 Lithium’s DLE Test Results

The table below outlines a summary of E3 Lithium’s DLE full results.

Lithium’s field pilot plant. These results do not represent the performance of a single test run and outline the

performance of individual runs for each result.

Results Discussion

E3 Lithium’s DLE system has demonstrated to achieve a high lithium recovery at much higher flow rate

ratios. A higher flow rate ratio can have a significant positive economic impact on the design of a

commercial facility for a given recovery. The concentration of lithium and that of the impurities varied

throughout the testing based on what the system was testing for, represented here with some indicative

results from the testing. However, the relative impurities generally have a smaller impact on the potential

costs. The information gathered enables E3 Lithium to continue to optimize to refine the quality of E3

Lithium’s DLE concentrate, and it is anticipated the team will improve the purity of the concentrate.

“In addition to the third-party results we’ve outlined previously, E3 Lithium’s proprietary DLE’s performance

surpassed our expectations,“ said Chris Doornbos, President & CEO of E3 Lithium. “The field pilot plant has

operated exactly as intended since its commissioning in August. Total testing has consumed more than 500

m3 of brine produced from the well at the pilot location, providing us with the data needed for the

commercial design and a deep understanding of the performance of various DLE technologies on our brine

resource.”

Next Steps

The Company plans to continue testing an additional third-party technology through the remainder of 2023

and likely into early 2024. E3 Lithium is reviewing the results from the two DLE systems already tested and

will compare them with the results of the third system once complete to determine the cost implications of

integrating them into the full process flow sheet.

With the positive results from these two systems now complete, the Company has paused site operations

and will continue testing the third system off-site to realize the cost savings associated with avoiding winter

operations. Given the learnings and success from the field pilot plant thus far, the Company can execute an

off-site pilot with similar operating conditions and quality of data with the additional benefit of cost

savings.

Based on the results of testing, commercial readiness of the systems and a fulsome understanding of the

associated economics, the Company will decide which technology to pursue for its first commercial facility.

The Company continues to work through the full process design for its Pre-Feasibility Study (PFS). The

fulsome project economics will be outlined within the PFS, taking into account the DLE results and other

process factors to produce a final battery quality lithium hydroxide.
