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.
Avalon is also advancing a Preliminary Economic Assessment intended to modernize the development
and processing approach contemplated in the historical feasibility study and evaluate the project's
economics. The work forms part of Avalon's broader strategy to advance Nechalacho toward
development while evaluating potential processing pathways, strategic partnerships and financing
opportunities.
Avalon believes Nechalacho's scale, advanced technical foundation, exposure to both light and heavy
rare earth elements and location within a stable Canadian jurisdiction position the project as a
compelling opportunity within North America's critical minerals industry.
