E3 Lithium’s Clearwater Project Selected for the Canada Investment Summit Prospectus; Company Establishes Strategic Advisory Group

E3’s Clearwater Project is part of Canada Investment Summit’s Prospectus aimed at attracting up to $1 trillion of total investment in Canada. The Company establishes experienced Strategic Advisory Group to support Clearwater Project’s progress towards commercialization

CALGARY, Alberta--(BUSINESS WIRE)--E3 LITHIUM LTD. (TSXV: ETL) (FSE: OW3) (OTCQX: EEMMF), “E3”, “E3 Lithium” or the “Company,” a leader in Canadian lithium development, announces that its Clearwater Project has been selected for inclusion in the Canada Investment Summit Prospectus (the “Prospectus”), a curated portfolio of investment-ready Canadian projects presented to global institutional investors, strategic partners and allied governments. Concurrently, the Company announces the formation of its Strategic Advisory Group, with the appointment of industry leaders Chris Slubicki, Dr. Mike Dixon, and Kyle Rousay.

“Inclusion in the Canada Investment Summit Prospectus recognizes that Clearwater is a project getting ready to be built,” said Chris Doornbos, CEO & Chair of E3 Lithium. “The maturation of the technology and engineering continues to demonstrate that the lithium resources in Alberta contain significant value, and producing battery ready products on site supports Canada’s initiative to supply the global battery and energy ecosystem. We are proud to represent Canada and Alberta’s lithium at this event. In line with E3’s progression and maturation, our new advisory group will be instrumental in supporting our strategy development and delivering on our goals.”

Clearwater Selected for the Canada Investment Summit Prospectus

The Canada Investment Summit (the “Summit”) is being hosted by Canadian Prime Minister, Mark Carney, in partnership with Canada Pension Plan Investment Board and Public Sector Pension Investment Board in Toronto, Ontario, on September 14 and 15, 2026. The Summit convenes international institutional capital, strategic industry participants, and government partners to attract up to $1 trillion of investment into Canada, including a shortlist of Canadian projects named in the Prospectus. Inclusion in the Prospectus is by selection only and reflects the technical maturity, strategic value, and investment-readiness of the selected projects. E3’s Clearwater Project’s inclusion reflects its combination of scale, technical maturity, infrastructure access, and jurisdictional advantages that few lithium projects possess simultaneously, anywhere in the world.

Resource scale. The Clearwater Project sits within Alberta’s Bashaw District, where E3 has defined 16.2 million tonnes of lithium carbonate equivalent (LCE) Measured and Indicated mineral resource¹, one of the largest lithium resource endowments in North America. The Company is progressing development of Stage 1 of the Project with a capacity of 12,000 tonnes per year of lithium carbonate with the resource and brine volume to support significant increases in production.

Engineered, not conceptual. E3’s Clearwater Project will produce battery ready products in Alberta, without the need for additional refining. The Front-End Engineering and Design (“FEED”) for the first of many facilities is underway, building on E3’s Pre-Feasibility Study completed in 2024, which confirmed Canada’s first proven and probable lithium brine reserve with an after-tax NPV_(8%) of US$3.7 billion¹. Operating the only lithium carbonate demonstration facility in Canada, E3 is currently proving the process at increasing scale.

Infrastructure and jurisdiction. The Clearwater Project is transitioning a historic producing asset; it leverages Alberta’s existing energy infrastructure, including roads, power, wellbore data, and an experienced workforce. Alberta provides a single, established regulator and a century of operating precedent; a materially different risk profile than greenfield lithium development in most other jurisdictions.

Advancing toward commercialization. The Company has made significant advancement in moving the Project from a concept, to resource and reserves identification, building and operating a Demonstration Facility, producing battery-grade lithium carbonate, submitting the Central Processing Facility permit application, and advancing its Feasibility Study as it progresses toward Final Investment Decision.

Formation of E3’s Strategic Advisory Group

E3 has established a Strategic Advisory Group (the “Advisors”), comprised of Chris Slubicki, Dr. Mike Dixon, and Kyle Rousay. The Advisors will support the CEO and the executive team, providing counsel on capital allocation, project financing, strategic partnerships and offtake, transaction execution, process design decisions, readiness for construction, and technology scale-up. These additions continue a deliberate build-out of senior capability ahead of commercialization, including Brian Newmarch’s appointment as Chief Financial Officer in mid-2025 and Tom Gear’s appointment as Chief Operating Officer in mid-2026.

Chris Slubicki is a founder and former President, CEO and Director of Modern Resources Inc., a Calgary-based producer he grew to 20,000 barrels of oil equivalent per day and which was recognized as an ESG leader and low-cost performer before its sale to Tourmaline Oil Corp. in 2020. He previously served as President and CEO of OPTI Canada Inc., where he and his team stabilized a financially and technically distressed oil sands producer and delivered its US$2.1 billion sale to CNOOC in 2011. Chris was one of four founders of Waterous & Co., the global oil and gas M&A firm sold to Bank of Nova Scotia in 2005 and later served as Vice-Chairman of Scotia Waterous. He holds a B.Sc. in Mechanical Engineering from Queen’s University and an MBA from the University of Calgary and is registered as a professional engineer with APEGA.

Dr. Mike Dixon is an entrepreneur and technologist with a track record of building and exiting process technology companies. He founded and led Synauta, a cleantech company applying data science and machine learning to desalination, through its acquisition by Gradiant four years after incorporation, and was a key contributor to the rapid global expansion of NanoH2O, acquired by LG Chem in 2014. He served as Chief Technology Officer of WaterNEXT, playing a key role in the company’s formation and program development, and has advised more than a dozen companies, including the MIT spinout Sandymount, acquired by Alfa Laval. Mike has authored over 80 publications, chaired the 2022 World Congress of the International Desalination and Reuse Association, and previously served as an advisor to E3 Lithium.

Kyle Rousay is Founder and Principal of Cedar & Stone Advisory, where he advises founders, boards and executive teams on strategy, growth, governance and corporate transactions, drawing on more than 20 years of leadership across mining, energy and technology. Previously, at Rio Tinto, he served as General Counsel for the Copper business and subsequently as General Counsel, Corporate, helping shape the company’s global copper growth strategy and guide major investments, project financing, M&A, project development and production ramp-up, including Arcadium Lithium in 2025. Kyle previously held senior roles with Schlumberger across North America, the Middle East and Asia, and began his career at Bennett Jones LLP in Calgary. Kyle holds a Bachelor of Commerce from the University of Calgary and a Juris Doctor from the University of Saskatchewan.
