Nechalacho Basal Zone Selected for Canada Investment Summit Prospectus as Strategic Canadian Rare Earths Project
Toronto, Ontario--(Newsfile Corp. - September 15, 2026) - Avalon Advanced Materials Inc. (TSX: AVL) (OTCQB: AVLNF) ("Avalon" or the "Company") is pleased to announce that its Nechalacho Rare Earths Project ("Nechalacho") in the Northwest Territories has been selected for inclusion in the Canada Investment Summit Prospectus and will be showcased by the Government of the Northwest Territories ("GNWT") as a strategic critical minerals development opportunity.
The inaugural Canada Investment Summit, hosted by the Government of Canada in partnership with Canada's major institutional investment organizations, is bringing together global investors and Canadian companies to highlight investment opportunities across the country. The Summit's official prospectus features 167 investment opportunities, including 63 projects in the minerals and metals sector, providing Nechalacho with exposure to international investors seeking opportunities across Canada's strategic resource industries.
Nechalacho's inclusion provides an important national and international platform to showcase both the project and the Northwest Territories' broader critical minerals potential. Premier R.J. Simpson and the GNWT are highlighting Nechalacho as one of the territory's key resource development opportunities, positioning the project among a select group of Canadian rare earth and critical minerals projects being presented to global investors at the Summit.
The selection comes as governments in Canada, the United States and allied markets increasingly focus on establishing secure, diversified supply chains for critical minerals. It also highlights the important role the Northwest Territories can play in strengthening Canada's domestic supply of critical minerals while creating opportunities for investment, economic development and long-term benefits for the territory.
Nechalacho is one of Canada's most advanced undeveloped rare earth assets, benefiting from substantial historical technical work, including a historical 2013 Definitive Feasibility Study, extensive drilling and supporting technical studies. Avalon recently announced an updated Mineral Resource Estimate for the Basal Zone prepared in accordance with U.S. SEC S-K 1300 requirements, providing an updated technical foundation for the project as the Company advances its U.S. listing and capital markets strategy.
