E3 Lithium Files Second Quarter 2025 Financial Statements and MD&A

and Announces Appointment of Lead Director

CALGARY, ALBERTA, August 27, 2025 – E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), “E3

Lithium” or the “Company,” a leader in Canadian lithium, today filed its Consolidated Financial Statements for

the three-month period ended June 30, 2025, and the accompanying Management’s Discussion and Analysis

(“MD&A”) on SEDAR www.sedarplus.ca. E3 Lithium has updated its corporate presentation, and along with

the financial statements, MD&A, it will be available on E3 Lithium’s website at www.e3lithium.ca.

Demonstration Facility Makes Significant Progress During the Quarter, Q3 Commissioning on Target

• On April 16, 2025 , E3 Lithium reported that the critical components of the lithium extraction equipment,

comprising the 30 -column Direct Lithium Extraction (“DLE”) system (the “30 -column system”) and

associated purification and concentration equipment for Phase 1 and Phase 2 of the Demonstration

Facility, were approximately 50% assembled.

• On June 2, 2025 , E3 Lithium reported that the aforementioned equipment was fully fabricated and

undergoing final inspections, with the skids on schedule to arrive and be assembled on -site in the

Clearwater Project area over a period of six to eight weeks. Subject to regulatory approval, the equipment

is expected to undergo assembly and operational and safety inspections, followed by final leak tests with

commissioning targeted to commence in Q3 2025.

• Subsequent to quarter end, E3 Lithium announced on August 12, 2025, that all major equipment for Phase

1 arrived on site and the DLE system and associated polishing and purification units were fully assembled

with supporting infrastructure being incorporated prior to the final mechanical, electrical checks and final

inspection and operational review.

Results from Phase 1 of the Lithium Metal Battery Joint Development Agreement

• On May 22, 2025, E3 Lithium announced the initial results from the battery cells manufactured under the

Joint Development Agreement with Pure Lithium Corporation (“Pure Lithium”), using E3 Lithium’s brine

and DLE technology with Pure Lithium’s extraction and battery technology . Multiple lithium chloride

concentrate variations developed within E3’s commercial production process within were used to

manufacture lithium metal battery-ready anodes at Pure Lithium’s facility in Boston. These anodes were

then assembled by Pure Lithium into batteries, and their electrochemical performance was evaluated in

full cells with notable results, including the various E3 Lithium brine streams achieving a very high purity

level of > 99.9% pure lithium metal as tested by ICP -OES analysis. The two companies continue to

collaborate on the development and planning of an integrated process that can deliver the highest purity

lithium metal anodes at the lowest possible cost.
