CALGARY, Alberta – E3 Lithium (TSXV: ETL, FSE: OW3, OTCQX: EEMMF), a Canadian lithium developer, announced it has successfully produced battery-grade lithium carbonate during the commissioning of Phase 1 of its Demonstration Facility. The company also unveiled an updated corporate presentation available on its website.
This milestone confirms the functionality of E3 Lithium’s direct lithium extraction (DLE) technology and associated equipment, validating the entire process flow, from initial brine extraction to final polishing and purification stages. Lithium chloride derived from the demonstration equipment achieved an average purity of 99.70% when converted to lithium carbonate.
The success of Phase 1 not only demonstrates the operational viability of the equipment but also reinforces the technology selection underpinning E3 Lithium’s commercial facility designs. E3 Lithium intends to continue operating Phase 1 through Q4 2025, processing brine into lithium carbonate. This output will be crucial for customer pre-qualification, potentially leading to future offtake agreements, a key step in securing long-term revenue streams.
“A key differentiator for E3 Lithium is our fully integrated process, from brine to battery-grade products,” stated Chris Doornbos, President and CEO of E3 Lithium. “Producing battery-grade lithium carbonate using a scaled-down version of our commercial facility design is a critical milestone for the Clearwater Project. This accomplishment validates the team’s hard work and dedication and allows E3 to advance engineering towards the commercial facility and move closer to a Final Investment Decision.”
E3 Lithium’s approach to lithium extraction hinges on its proprietary DLE technology, which aims to minimize environmental impact while maximizing lithium recovery rates. This technology could be especially relevant as investors and automakers alike place greater emphasis on sustainable sourcing of battery materials.
Multiple samples from the initial lithium carbonate production were analyzed, revealing an average purity of 99.70%. These analyses were conducted in E3 Lithium’s lab using the ISO TC 333 testing methodology. To ensure transparency and accuracy, samples will also be sent for third-party verification.
Phase 2 of the Demonstration Facility will involve drilling a production and injection well pair to support reservoir development activities and enable continuous lithium carbonate production. The data collected during Phase 2 promises to provide crucial operational and engineering insights, informing the company’s Feasibility Study and underpinning its Final Investment Decision for the Clearwater Project.
E3 Lithium holds a significant resource base in Alberta and Saskatchewan, with 21.2 million tonnes of lithium carbonate equivalent (LCE) Measured and Indicated resources, and 2.8 Mt LCE Inferred mineral resources . A pre-feasibility study for the Clearwater Project outlined a 1.13 Mt LCE proven and probable mineral reserve with a pre-tax NPV(8%) of USD 5.2 Billion and an after-tax NPV(8%) of USD 3.7 Billion .
The successful commissioning of Phase 1, coupled with the company’s resource portfolio, positions E3 Lithium as a player in the burgeoning lithium market. As demand for electric vehicles continues to rise, securing reliable and sustainable sources of lithium becomes increasingly critical. E3 Lithium hopes its technology and strategic approach will allow the company to capitalize on this growing demand in a responsible manner.

Forward-looking statements are based on the current opinions, 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 additional financing needed will be available on reasonable terms; the exchange rates for the U.S. and Canadian currencies will be consistent with the Company’s expectations; that the current exploration, development, environmental and other objectives concerning the Demonstration Facility can be achieved and that its other corporate activities will proceed as expected; that general business and economic conditions will not change in a materially adverse 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 exploration and development, fluctuating commodity prices, the effectiveness and feasibility of emerging lithium extraction technologies which have not yet been tested or proven on a commercial scale or on the Company’s brine, risks related to the availability of financing on commercially reasonable terms and the expected use of proceeds; operations and contractual obligations; changes in estimated mineral reserves or mineral resources; future prices of lithium and other metals; availability of third party contractors; availability of equipment; failure of equipment to operate as anticipated; accidents, effects of weather and other natural phenomena and other risks associated with the mineral exploration industry; the Company’s lack of operating revenues; currency fluctuations; risks related to dependence on key personnel; estimates used in financial statements proving to be incorrect; competitive risks and the availability of financing, as described in more detail in our recent securities filings available under the Company’s profile on SEDAR+ (www.sedarplus.ca).
