E3 Lithium Advances Lithium Production Testing and

Provides Field Pilot Plant Commissioning Update

CALGARY, ALBERTA, August 23, 2023 – E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), “E3

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

announced it has successfully produced lithium carbonate, the last major step in a conventional process

before conversion to battery quality lithium hydroxide monohydrate (LHM).

The test work used concentrate generated from brines located in E3 Lithium’s Clearwater Project Area,

produced during the Direct Lithium Extraction (DLE) testing completed in preparation for the pilot plant.

E3 Lithium has engaged a major lithium refining technology and equipment vendor to develop the

downstream lithium production processes in preparation for the upcoming Pre-Feasibility Study. The testing

was conducted to treat a sample of concentrate, or eluate, produced by DLE technology. The test program

has successfully progressed through the coarse purification and concentration phases, and the eluate has

been converted into lithium carbonate. The final steps include further downstream polishing to achieve the

desired purity and then conversion of the carbonate into battery-grade LHM.

As the pilot plant produces more concentrate, E3 Lithium will be creating more carbonate and LHM for

commercial development purposes. Outlined in the picture below is a sample of the lithium carbonate

produced during the current test program.

Lithium Carbonate Produced from E3 Lithium’s Brines

“Producing high quality carbonate from our Leduc brines with a major equipment vendor is an incredibly

exciting milestone for the Company,“ said Chris Doornbos, President and CEO of E3 Lithium. “While

downstream lithium refining processes are already commercially operating, demonstrating the success of

these processes on E3 Lithium’s brine provides more certainty for our commercial processes.”

The objectives of the test program are to validate the downstream flowsheet, generate data required for

engineering design purposes and produce LHM for potential offtake partners. E3 Lithium will provide

updates as its test program progresses.
