CALGARY, Alberta -- (Business Wire)

E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), (“E3 Lithium” or the “Company”) a leader in Canadian lithium development, has successfully drilled its brine production and injection wells at its Demonstration Facility in central Alberta. This achievement marks a milestone in Phase 2 of the Company’s Demonstration Facility program.

The vertical production and deviated injection wells are E3 Lithium’s third and fourth wells into the Leduc Formation, and two of the five E3 operated wells within the Clearwater Project area. Drilling operations were completed as planned, reaching total depths past the Leduc and into the Cooking Lake Formation. The wells intercepted approximately 200m of Leduc aquifer, as anticipated for the producing zone in this area. Coring and comprehensive logging within the targeted reservoir will support the upcoming production testing. The next phase of operations includes the completions and production testing, which will continue into the first quarter of 2026. Lithium and water chemistry data will be available upon production test commencement. During the production test, the Company will be continually monitoring brine and gas chemistry, while collecting brine for use within the processing equipment to produce lithium carbonate.
