  Drilling Underway at the Demonstration Facility
 
 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 commenced drilling of its  lithium development well as part of Phase 2 of its Demonstration  Facility development in central Alberta.
 
 This is E3 Lithium’s third lithium well drilled into the Leduc  Formation. This next step in development builds upon the successful  production of battery-grade lithium carbonate during Phase 1 of the  Demonstration program in early October 2025. Phase 1 validated the  design of E3 Lithium’s Direct Lithium Extraction (DLE) equipment at this  scale. Results from this well will provide additional reservoir  performance data and brine analytics to support the design of the  commercial lithium facility. The objectives of this next drilling phase  include:
 
 
 “This well kicks off the second phase our Demonstration program, another  important step forward as we advance toward commercial operations,”  said Chris Doornbos, President and CEO of E3 Lithium. “Our drilling  activities provide important data to inform our continued project design  and enhances our understanding of reservoir performance capabilities.” Validating subsurface geology through detailed analysis of core samples  and integrate petrophysical properties derived from comprehensive  well-logging datasets   Collecting reservoir data to inform commercial wellfield and facility design   Providing brine for continued operation of its DLE and processing  equipment previously commissioned in Phase 1 of the Demonstration  Facility   Support engineering and permitting work for E3 Lithium’s upcoming commercial facility  
 
 Drilling and testing activities are expected to continue into November  and the Company will provide updates on drilling and testing operations.
