E3 Metals Successfully Commissions Lab-Pilot Prototype

CALGARY, Oct. 20, 2021 - E3 Metals Corp. (TSXV: ETMC) (FSE: OU7A) (OTC: EEMMF) (the "Company" or "E3 Metals"), an emerging lithium developer and leading direct lithium extraction ("DLE") technology innovator, is pleased to announce that the Lab-Pilot Prototype (the "Prototype") construction has been completed. After a series of commissioning tests, the unit is successfully operating as expected.

The Prototype has begun the extraction test program this week using E3 Metals' sorbents using lithium-enriched formation water from the Leduc Aquifer. The Prototype has been operating at relatively high flow rates and being fully automated, allows for 24/7 operations and testing. The Prototype is the largest scale processing equipment E3 Metals has operated to date and allows for larger volumes and consistent test cycles that closely resemble commercial operations. This testing program will complete a series of operational runs that will provide critical information for the development and design of the Field Pilot.

"This is another key milestone achieved by our technical team" commented CEO, Chris Doornbos. "They continue to deliver results which validate the DLE technology on a continually larger scale. We look forward to the next stage of development, with the expectation to be designing the Field Pilot in early 2022 after the successful testing program conducted with this Prototype."
