E3 Lithium Successfully Commissions Lithium Carbonate Reactors in the

Lab for Use in Field Demonstration

CALGARY, ALBERTA, September 26, 2024 – E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF),

“E3 Lithium” or the “Company,” a leader in Canadian lithium, is pleased to announce the successful

commissioning of its demo scale carbonate conversion reactors. This allows the Company to produce

lithium carbonate using similar, yet small-scale equipment operating at the same temperature and chemical

operating conditions as a commercial system. The ability to produce reliable battery grade lithium

carbonate is a significant step forward in the Company’s efforts to establish a reliable lithium production

facility in Alberta, Canada.

The reactors will eventually be used in the previously announced demonstration facility. The goal is to

confirm the operational parameters in the lab ahead of the demo being commissioned on site. The

commissioning of the carbonation reactors involved a series of tests that confirmed its efficiency and

reliability, consistently meeting the required reaction conditions. This comes following E3 Lithium’s

expansion to its Calgary-based lab to incorporate advanced equipment with the goal of producing battery-

grade lithium carbonate. The lab has focused on the procurement of the equipment and the development of

the processes and procedures to ensure safe and efficient operations. Future test work will center around

optimization, enhancing the Company’s ability to scale up production efficiently while prioritizing accuracy,

cost-effectiveness and operational flexibility, aiming for the production of battery grade lithium carbonate

from E3 Lithium’s concentrate generated at the pilot last year.

“This achievement expands our in-house capabilities from advancing DLE to producing battery grade lithium

carbonate,” said Chris Doornbos, President and CEO of E3 Lithium. “By expanding our Calgary lab with

advanced equipment and know-how for producing battery-grade lithium carbonate, E3 can advance its

engineering initiatives with more efficiency and lower cost. These developments strengthen E3’s ability to

establish a reliable and competitive lithium supply in Alberta that will help with the increasing demand for

battery-grade lithium in North America.”

estimates and assumptions of management in light of its experience, perception of historical trends, and

results of the PFS, but such statements are not guarantees of future performance. In particular, this news

release contains forward-looking information relating to: the estimated mineral resources and mineral

resources at the Clearwater Project; expectations regarding the PFS, including statements regarding the

results of the PFS and interpretations thereof; expectations concerning the Clearwater Project, including

extraction, production, pretreatment, purification, volume reduction and conversion process and features

and the expected outcomes thereof; the expected economic performance of the Clearwater Project,

including capital costs, operating costs, water usage, land use and carbon emissions; statements regarding

the Company’s strategy for minimizing environmental impact and liquid waste and maximizing water reuse,

with no planned tailings or waste piles; the potential for a secondary revenue stream should the Company

be able to sell the calcium carbonate generated during the production of lithium hydroxide; plans and

objectives of management for the Company’s operations and the Clearwater Project; and the inherent

hazards associated with mineral exploration and mining operations. In preparing the forward-looking

information in this news release, the Company has applied several material assumptions, including, but not

limited to, that any additional financing needed will be available on reasonable terms; the exchange rates

for the U.S. and Canadian currencies will be consistent with the Company’s expectations; that the current

exploration, development, environmental and other objectives concerning the Clearwater Project can be

achieved and that its other corporate activities will proceed as expected; that the current price and demand

for lithium will be sustained or will improve; that general business and economic conditions will not change

in a materially adverse manner and that all necessary governmental approvals for the planned activities on
