CALGARY, Alberta — E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), “E3 Lithium” or the “Company,” a leader in Canadian lithium, is excited to announce it is expanding the Calgary-based lab to incorporate the equipment to complete the polishing and production of battery products, such as lithium carbonate and lithium hydroxide.

E3 Lithium’s development facility, located at the University of Calgary, has been operational since early 2021. The facilities’ focus has been on the development and verification of Direct Lithium Extraction (DLE) processing technologies. The internal team of experts has been beneficial in ensuring that E3 Lithium successfully completed the necessary steps towards technology development and selection, including verification testing of third-party DLE processes to support the design and decision making for the commercial facility. E3 also has its own internal analytics team that enables the Company to efficiently and quickly produce consistent results from the various testing processes.

With the definition of the downstream processes utilizing chemical conversion to produce lithium carbonate and then lithium hydroxide, E3 will deploy the same validation, verification and optimization strategy to the conversion processes. This includes building scaled down process equipment that mimics the commercial systems to validate and optimize the production of lithium carbonate. The team will further investigate the necessity to complete the equipment to continue from carbonate to lithium hydroxide. This work will support E3 Lithium’s feasibility engineering study and future commercial operations.

“Developing this capability in-house offers significant advantages in terms of result accuracy, cost-effectiveness and flexibility” said Chris Doornbos, President and CEO of E3 Lithium. “By building and operating scaled down equipment that closely mimics commercial operations, our highly skilled lab team will verify and optimize the process. The results the lab will produce will support the design and operation of the Company’s commercial plant and will bring efficiency to our future commercial operations by offering prompt and accurate data and analysis.”

The Post-DLE to Lithium Carbonate Flowsheet

DLE technology extracts lithium ions from E3 Lithium’s brine efficiently and effectively producing a lithium rich concentrate stream. The process to convert the lithium rich solution (a liquid) to lithium carbonate (a solid) utilizes conventional chemical reactions and industry standard processes and is comprised of two main steps: purification with volume reduction and precipitation of lithium products.

• Purification and Volume Reduction: This step removes the contaminants, mainly calcium, magnesium and boron, from the DLE lithium rich product stream, further concentrates the lithium stream and recovers water for reuse in the process. Example of process technology used in this step can include precipitation, nanofiltration, ion exchange, reverse osmosis (RO) and evaporation.
• Precipitation: The final step involves a conversion process achieved by mixing soda ash with the purified, concentrated lithium solution to produce a solid lithium carbonate (Li2CO3) precipitate.
