E3 Lithium Produces Battery Grade Lithium Carbonate from its
Phase 1 Demonstration
CALGARY, ALBERTA, September 22, 2025 – E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX:
EEMMF), “E3”, “E3 Lithium” or the “Company,” a leader in Canadian lithium, has produced
battery grade lithium carbonate while commissioning Phase 1 of its Demonstration Facility.
Additionally, E3 has updated it s corporate presentation which is now available on its
website (www.e3lithium.ca).
The successful production of battery grade lithium carbonate from the Phase 1
commissioning confirms E3’s Demonstration Equipment is fully functional and the field
site for Phase 1 is fully operational along the entire process flow, from direct lithium
extraction (“DLE”) through to the polishing and purification stages. Lithium chloride
produced from the Demonstration Equipment has now been successfully converted to
lithium carbonate with an average purity of 99.70%.
The Phase 1 demonstration success validates both the operability of the equipment and the
technology selection supporting E3 Lithium’s commercial facility designs. E3 Lithium will
continue to operate Phase 1 of the Demonstration Facility into Q4 2025, processing brine
through to lithium carbonate, which will be used, in part, for customer pre-qualification that
underpins potential offtake agreements.
“One of the key differentiators of E3 Lithium is its full y integrated process, from brine to
battery grade products,” said Chris Doornbos, President and CEO of E3 Lithium.
“Showcasing E3’s ability to produce battery -grade lithium carbonate with a scale d down
version of the commercial facility design is a critical milestone for the Clearwater Project.
Being able to accomplish this goal at this early stage of operations showcases the hard work
and dedication of the team at E3 Lithium supporting the work on site. This milestone enables
E3 to progress the engineering towards the commercial facility and moves the Company one
step closer towards Final Investment Decision.”
Lithium chloride produced from the Demonstration Equipment was converted to lithium
carbonate. Four separate samples were collected from some of the first lithium carbonate
produced and analyzed for purity, averaging 99.70% lithium carbonate . The analysis was
conducted in the E3 Lithium lab following the ISO TC 333 testing methodology that is being
validated in part by E3 Lithium and the participation in the mirror committee. Samples will
be sent for 3rd party analysis and verification. Conversion of the lithium chloride into lithium
carbonate will be ongoing during the operation of the Demonstration Facility.

Phase 2 of the Demonstration Facility includes the drilling of a production and injection well
pair that supports reservoir development activities and enable s continuous lithium
carbonate production from the Company’s brine feed. Phase 2 operations will continue to
deliver important operational and engineering data that will feed the development of our
Feasibility Study and support the Final Investment Decision on E3 Lithium’s Clearwater
Project.

This news release includes certain forward -looking statements as well as management’s objectives,
strategies, beliefs and intentions or forward -looking information within the meaning of applicable securities
laws. Forward-looking statements are frequently identified by such words as “believe”, “may”, “will”, “plan”,
“expect”, “anticipate”, “estimate”, “intend”, “project”, “potential”, “possible” and similar words referring to
future events and results. Forward -looking statements are based on the current opi nions, expectations,
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 expected timelines for the assembly, testing and
commissioning of the demonstration equipment; production, pretreatment, purification, volume reduction and
conversion process and features and the expected outcomes thereof; the Company’s expectations regarding
the production of lithium carbonate; plans and objectives of management for the Company’s operations of
the Demonstration Facility ; 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 additiona l financing needed will be
available on reasonable terms; the exchange rates for the U.S. and Canadian currencies will be consistent

manner and that all necessary governmental approvals for the planned activities on the Demonstration
Facility will be obtained in a timely manner and on acceptable terms.
All forward-looking information (including future-orientated financial information) is inherently uncertain and
subject to a variety of assumptions, risks and uncertainties, including the speculative nature of mineral
