E3 Lithium Begins Operations of Alberta’s First

Direct Lithium Extraction Field Pilot Plant

CALGARY, ALBERTA, August 29, 2023 – E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), “E3

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

announces that commissioning of its Direct Lithium Extraction (DLE) field pilot plant is complete and

operations have begun.

The commissioning process included connecting all major pieces of equipment to the piping and wiring

systems on site. The team has also conducted a series of necessary inspections and system tests to

ensure safe and successful operations. Each DLE system has demonstrated it is operating as expected

based on the performance metrics established during pre-pilot testing.

The operations begin with running the DLE processes at different system parameter settings to determine

the most efficient extraction of lithium, guided by the Key Performance Indicators (KPIs) outlined on June

14, 2023. Upon determining a specific set of operating parameters, each system will run for a longer

duration to accomplish two tasks: 1) confirm consistent results over an extended period; and 2) produce

large volumes of lithium concentrate for further refining into lithium products, such as lithium hydroxide.

The data collected throughout the pilot operations will be primarily used to inform the commercial design of

the processing facility for our Pre-Feasibility Study (PFS) and Feasibility Study (FS).

“The start of full operations is a testament to the hard work the team has been putting in to get this

equipment running,” said Chris Doornbos, President and CEO of E3 Lithium. “This is a foundational moment

for E3 Lithium, as demonstrating DLE at pilot scale will enable us to move forward in developing this lithium

asset in Alberta towards commercialization.”
