E3 LITHIUM DELIVERS BATTERY-GRADE LITHIUM CARBONATE FROM ITS DEMONSTRATION PROGRAM TO GLOBAL PARTNERS AND OFF-TAKERS

E3 Lithium Ltd. has delivered and will continue to deliver battery-grade lithium carbonate produced from its demonstration program to multiple parties as part of its engagement with targeted offtake and strategic partners.

"This milestone marks an important step in E3's commercial process toward securing long-term offtake agreements and advancing our relationships with key players in the battery and critical minerals industry," said Chris Doornbos, president and chief executive officer of E3 Lithium. "Our ability to continually produce significant quantities of lithium carbonate from our demonstration facility highlights the size and sophistication of our operations."

E3 Lithium continues to produce battery-grade lithium carbonate from lithium chloride generated from its direct lithium extraction process, all now operating as part of its demonstration program in Alberta. The company is now shipping 0.5-kilogram lots to prospective parties across the lithium battery industry, with several requesting multiple kilograms for additional analysis.

The demonstration equipment was designed based on the prefeasibility study published in 2024, fabricated in early 2025 and deployed to site for phase 1 in the third quarter of 2025. The team achieved the targeted specifications for battery-grade lithium carbonate within three weeks of commissioning, showcasing the strength of the facility design. The delivery of E3's lithium carbonate to potential customers is part of a structured qualification process and E3's lithium carbonate has consistently met the targeted level of purity across all potential contaminants required for battery applications.

The demonstration program is being conducted within the company's flagship Clearwater project to collect data and operational information to complete E3's front-end engineering and design (FEED) leading to the publication of a feasibility study. The Clearwater project is an advanced-stage lithium carbonate production facility in development, 15 kilometres east of Olds, Alta., approximately one hour north of Calgary, Alta. The company has proposed a staged development plan with a capacity of 12,000 tonnes of lithium carbonate per year as the first stage of production and expansion potential to up to 36,000 tonnes of lithium carbonate per year.

E3 Lithium is advancing its development activities in parallel with commercial offtake agreements as the Clearwater project advances toward being shovel ready.

About E3 Lithium Ltd.

E3 Lithium is a development company with total mineral resources of 21.2 million tonnes of lithium carbonate equivalent (LCE) measured and indicated as well as 300,000 tonnes LCE inferred in Alberta. The Clearwater prefeasibility study outlined a 1.13-million-tonne-LCE proven and probable mineral reserve with a pretax net present value (discounted at 8 per cent) of $5.2-billion (U.S.) with a 29.2-per-cent internal rate of return and an after-tax NPV (discounted at 8 per cent) of $3.7-billion (U.S.) with a 24.6-per-cent IRR.
