LEADING EDGE MATERIALS' INVESTOR UPDATE AND SIGNIFICANT ACTIVITIES

LEADING EDGE MATERIALS’ INVESTOR UPDATE ON SIGNIFICANT ACTIVITIES

Vancouver, June 22, 2025 – Leading Edge Materials Corp. (“Leading Edge Materials” or the “Company”) (TSXV: LEM) (Nasdaq First North: LEMSE) (OTCQB: LEMIF) provides an investor update on significant activities.

Overview - Becoming a European CRM producer

Concerns about critical raw materials - security of supply, supply chain resilience and defence requirements - have been recurring themes at conferences attended by the Company in recent months, with Heavy Rare Earth Elements (“HREEs”) and natural graphite frequently mentioned; geopolitical uncertainty is the new norm and it is driving partnership, collaboration and greater levels of support for mining.

On June 17, 2025, the G7 Critical Minerals Action Plan was announced focused on ‘diversifying the responsible production and supply of critical minerals, encouraging investments in critical mineral projects and local value creation, and promoting innovation’ in the G7, and with partners beyond, working together and ‘to swiftly protect our economic and national security’'.

At the EIT Raw Materials Summit in March, graphite and defence were frequent mentions on the first day, with widespread calls for more action, now the Critical Raw Materials Act is in force, and the need for more money.

Against this backdrop, LEM’s Critical Raw Materials (“CRMs”) portfolio is very well positioned and the Company is working on becoming a European CRM producer.

Norra Kärr is a globally significant source of HREEs with the economic advantage of valuable industrial minerals, specifically nepheline syenite; a production start within 3–4 years is in reach. In parallel, we are evaluating the restart of production from the fully built and permitted Woxna Graphite mine.

On exploration, and possibly future production, we have strengthened our position in Romania, with Leading Edge Materials Romania (“LEMR”) being granted ownership and operational permits for the Avram Iancu mine by CNCAN (National Commission for Control of Nuclear Activities) under the supervision of IAEA (International Atomic Energy Agency) and European Atomic Energy Community (EURATOM).

This is significant recognition of the funds invested and commitment made by the Company in country and gives us real ‘owner-operator’ autonomy over a deposit described as ‘one of the most important deposits [historically] in operation in Bihor (IAEA report, November 1997) and noted for uranium, copper, lead, nickel and zinc mineralization (IMWA Symposium 2007: Water in Mining Environments, May 2007).
