E3 Lithium begins commissioning at Clearwater demo site

Executive Summary

• E3 Lithium began commissioning Phase 1 of its Clearwater Project demonstration facility, targeting full operation of the 30‑column DLE system and purification equipment.
• Initial brine feed into the DLE system was completed; a one‑week commissioning period is expected before lithium chloride production begins.
• Sufficient on‑site brine reserves will support Phase 1 operations into early Q4 2025, with results to be reported as they become available.

Key Details

• Phase 1 Scope: Operate 30‑column Direct Lithium Extraction (DLE) system and downstream polishing/purification units to produce high‑purity lithium chloride for conversion to battery‑grade lithium carbonate.
• Commissioning Timeline:
• Final testing & operational reviews completed late last week.
• Brine introduction into DLE system occurred over the past weekend.
• Expected one‑week period to fully commission DLE system, followed by initialization of purification units.
• Operational Goal: Validate equipment functionality under real‑time conditions and generate high‑quality lithium chloride as a feedstock for carbonate production.
• Brine Supply: On‑site brine inventory sufficient to run Phase 1 DLE and purification units into early Q4 2025.
• Future Plans: Upon successful completion of Phase 1, the facility will transition to full operations; Phase 2 commissioning is slated to begin later in the fall.
• Management Quote: Chris Doornbos, President & CEO, stated that Phase 1 commissioning “highlights the equipment is in full working order and is an exciting next step…”.
