E3 Lithium Limited provide an update on the selection process for Direct Lithium Extraction (DLE) technology and the design of the downstream refining flowsheet for its first commercial facility. In 2023, E3 Lithium committed to operating a field pilot plant to test DLE technologies at continuous scale to demonstrate the technical capability of various technologies to extract lithium efficiently from E3 Lithium?s brines. At the pilot, the Company operated its proprietary DLE technology and a third-party technology which produced successful results.

In parallel, to ensure the Company had evaluated the available options to select the combination of processes that produce the best technical and economic results for its commercial design, E3 Lithium evaluated an additional three third-party DLE systems. The results of all the DLE technologies were similar to the results outlined from the pilot testing in terms of the recovery and lithium concentrate quality. The most significant information received from all testing of DLE technologies that E3 Lithium completed was that each achieved technical success, which has significantly de-risked the commercial viability of the Company?s Leduc brines and Clearwater Project. The results also provided sufficient data to allow the Company to analyze each of the leading DLE options in combination with the downstream refining process, to select the optimal design for inclusion into E3 Lithium?s Prefeasibility Study (PFS).

The Company?s primary goal is to make a decision that will enable immediate progression into the Feasibility Study and onto commercial construction and operations. In selecting the technology for its first commercial facility, E3 Lithium is prioritizing, above all else, the most viable path to commercial operations with the most attractive economics. Other important factors include the ability for the third party to provide a performance guarantee, the commercial readiness of the technology and the operability of the processes.

These factors become paramount as all DLE technologies tested produce the required technical results and lithium concentrate solutions suitable for downstream refining into battery-grade lithium. As a result, E3 Lithium is proceeding with using third-party technology at its first commercial facility as the best option to meet the Company?s goals. Selecting third-party technology with advanced commercial readiness supports E3 Lithium?s commercialization plans in the near term.
