E3 Lithium said commissioning of phase 1 of the Demonstration Facility is underway and on schedule. Phase 1 involves operating the 30-column DLE system and polishing and purification equipment. The objective of phase 1 is to fully operationalize the DLE system and purification units to produce a high-quality lithium chloride, which will support the production of battery-grade lithium carbonate.

Final testing and operational reviews were completed late last week; the first stage of commissioning is the introduction of brine into the DLE system, which occurred over the past weekend. The company expects the initial DLE system to take approximately one week to full commission. After which, the purification units will be initialized and lithium chloride produced from the DLE system will flow through this system, completing the commissioning stages of phase 1.

Once both the DLE system and purification units have completed their respective commissioning stages, the Demonstration Facility will shift to full operations. The main goals of phase 1 are to ensure the equipment is in operating order after assembly, confirm both systems functionality under real-time operating conditions and produce a high-quality lithium chloride for conversion into battery-grade lithium carbonate.

E3 Lithium has sufficient brine on site to enable the operation of the phase 1 DLE and purification units into early Q4, 2025, and the company expects to provide updates as operations progress and results become available. 

“The commissioning of phase 1 of our Demonstration Facility highlights the equipment is in full working order and is an exciting next step for the advancement of this facility. The results from phase 1 will ensure that our process is fully optimized and ready for phase 2 of the Demonstration Facility that is set to begin later this fall,” said Chris Doornbos, president and CEO.


E3 Lithium is a development company with a total of 16 million tonnes of lithium carbonate equivalent (LCE) measured and indicated and 0.9 million tonnes LCE inferred mineral resources in Alberta. As outlined in E3’s preliminary economic assessment, the Clearwater Lithium Project has an NPV8 percent of $1.1 billion with a 32 percent IRR pre-tax and $820 Million with a 27 percent IRR after-tax. 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.
