CALGARY, Alberta--(BUSINESS WIRE)--Aug. 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.

Lead Director Elected

At the quarterly board of directors meeting, the Directors appointed Alexandra Cattelan as Lead Director. Ms. Cattelan’s appointment as Lead Director follows leading governance standards and supports E3 Lithium’s ongoing commitment to overall corporate governance. Ms. Cattelan has extensive experience in leading electric propulsion and advanced mobility programs and lithium battery development from her past roles with General Motors, Stellantis, and Johnson Controls.
