E3 LITHIUM PROVIDES DEMONSTRATION PLANT PROGRESS UPDATE, REMINDER OF WEBINAR TODAY AT 9AM MT

E3 Lithium Ltd. has provided a progress update on its demonstration facility, which is planned to be commissioned in 2025. As previously announced on Feb. 25, 2025, the demo facility will be brought on stream in three phases over the second half of 2025.

The critical pieces of equipment being manufactured for phase 1 and phase 2 of the demo facility are the 30-column process optimization equipment and the polishing equipment. These components will produce a highly purified lithium chloride that will be converted into battery-quality lithium carbonate, using equipment that is currently operating in E3 Lithium's laboratory in Calgary, Alta., that will be integrated into the demo facility.

All of the critical components for the five skids being constructed have been procured and the skids are approximately 50 per cent assembled. The valve control skid will operate the 30-column DLE (direct lithium extraction) skid and one of the polishing skids. While delays can occur, the equipment remains on schedule for Q2 completion and arrival on site in Q3. Installation, assembly and commissioning will commence in Q3, subject to regulatory approval.

E3 plans on drilling two wells, a production and injection pair, to complete a subsurface demonstration, also planned for Q3. Later in 2025, E3 will begin preparation for phase 3, which includes the installation of a commercial-scale DLE column. The three phases of the demo facility aim to fully validate the processing technology and produce battery-grade lithium carbonate from Leduc Brines, which will significantly derisk the process heading into the completion of feasibility and commencement of project financing for E3 Lithium's Clearwater project.

"It is always very exciting to see equipment being assembled," commented Chris Doornbos, E3 Lithium's chief executive officer. "A lot of design and process engineering has gone into ensuring this equipment is built to operate effectively. I want to thank the team for their commitment and focused efforts to deliver high-quality results and the fabricators for working diligently and safely to remain on schedule."

As previously announced, the company is hosting a webinar this morning, April 16, 2025, at 9 a.m. MT, to provide commentary on current trends in the lithium and broader markets and review an update of the company's 2025 development plans and recent announcements as found in the recently updated corporate presentation available on E3 Lithium's website.

About E3 Lithium Ltd.

E3 Lithium is a development company with a total of 16.2 million tonnes of lithium carbonate equivalent (LCE) measured and indicated as well as 900,000 tonnes LCE inferred mineral resources in Alberta and 2.5 million tonnes LCE inferred mineral resources in Saskatchewan. 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. E3 Lithium's goal is to produce high-purity, battery-grade lithium products to power the growing electrical revolution. With a significant lithium resource and innovative technology solutions, E3 Lithium has the potential to deliver lithium to market from one of the best jurisdictions in the world.
