E3 LITHIUM PRODUCES BATTERY QUALITY LITHIUM CARBONATE WITH DEMONSTRATION-SCALE EQUIPMENT

E3 Lithium Ltd. has successfully produced battery-quality lithium carbonate from Leduc brines using its demonstration-scale equipment, operated in its laboratory in Calgary.

The production of lithium carbonate achieves a battery-quality purity of 99.71 per cent based on internal analysis as outlined in the Jan. 15, 2025, announcement. Achieving this purity as an initial result is an incredible achievement by the team. The ability to produce reliable and consistent lithium carbonate at battery-quality specifications will be an important factor in attracting partners and offtakers to the project. Further work is planned to test various operating parameters ahead of the demonstration facility operations. More details on the full demonstration program will be provided by E3 Lithium in the coming weeks.

"Outlining consistent success through each of the development steps is significant as we prepare for the demonstration," said Chris Doornbos, president and chief executive officer of E3 Lithium. "Developing battery-quality lithium carbonate at this scale brings us closer to proving Alberta's potential as a reliable source of lithium production, ready to meet market demand."

The team produced the battery-quality lithium carbonate using lithium chloride concentrate produced from the pilot operations in 2023. The production process utilized in the laboratory was conducted using the same conditions and equipment planned for the full-scale lithium brine demonstration facility, which follows those outlined for the commercial facility outlined in the Clearwater prefeasibility study.

By testing and optimizing each stage in a controlled lab setting, E3 Lithium is ensuring a smooth transition to battery-grade lithium carbonate production as it scales up to full operational capacity. In phase 1 of development, announced on Sept. 26, the lab focused on commissioning reactors specifically designed to produce lithium carbonate with consistency and reliability. This successful production of battery-quality lithium carbonate using concentrate produced from the Leduc aquifer provides significant confidence in the full process and the capabilities of the team at E3.

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.
