MINING INSPECTORATE RECOMMENDS MINING LEASE APPROVAL FOR LEADING EDGE MATERIALS’ NORRA KÄRR HEAVY RARE EARTH ELEMENTS PROJECT - SUBMITS TO THE SWEDISH GOVERNMENT FOR A FINAL DECISION

Vancouver, March 10, 2026 – Leading Edge Materials Corp. (“Leading Edge Materials” or the “Company”) (TSXV: LEM) (Nasdaq First North: LEMSE) (OTCQB: LEMIF) (FRA: 7FL) is pleased to announce that The Swedish Mining Inspectorate (Sw. Bergsstaten) has chosen to submit the Company’s 100% owned Swedish subsidiary Greenna Mineral AB’s (“GMAB”) application for an Exploitation Concession for Norra Kärr to the Swedish Government for a final decision.

The Mining Inspectorate itself recommends in its decision that the application (Norra Kärr K nr 2) should be approved. This follows the positive consultation responses from the County Administrative Boards (“CABs”) of Jönköping and Östergötland in December last year.

Key Facts

• Norra Kärr is a globally significant source of HREEs with the economic advantage of valuable industrial minerals, specifically nepheline syenite. Today, Europe relies almost exclusively on China for its imports of HREEs. China dominates the rare earth elements supply chain.
• Developing Norra Kärr is of great importance not only for Sweden, but for Europe. Geopolitical tensions and unstable global trade flows mean that it is more important than ever to produce HREEs in the region and establish supply chain resilience.
• The Swedish Geological Survey (“SGU”) discovered Norra Kärr in the 1900s and, in 2011, designated it as being of National Interest due to the significance of its rare earth elements (“REEs”) for Sweden and Europe.
• With the respect to the Company’s application for an Exploitation Concession, SGU in its capacity as an expert authority for issues relating to geology and minerals in Sweden has stated that the deposit at Norra Kärr is very important for Sweden's and the EU's supply of rare earth metals, and that Norra Kärr is one of Europe's richest deposits for these minerals – especially with regard to HREEs.
• Norra Kärr is estimated to produce approximately 248 tonnes of Dysprosium and 36 tonnes of Terbium oxides annually over an initial 26-year mine life - covering only 30 percent of the currently defined resource.
• Dysprosium and Terbium are HREEs that are essential to European manufacturing of permanent magnets, which in turn are crucial for the development of components for electric vehicles, wind turbines and military applications.

Kurt Budge CEO comments:         

"We are pleased that all government agencies involved in this permitting process so far have recommended approval of our application. Developing Norra Kärr is essential to building European supply chain resilience for Heavy Rare Earth Elements (HREE), which is crucial for Swedish and European security as well as the energy transition.

We note that while there may be differing views on the specific conditions to be included in the Exploitation Concession, these details can be worked through and addressed constructively and quickly.   With the Mining Inspectorate confirming that all requirements are met and the CABs having previously endorsed the application, we are excited to progress our work to fully permit and develop Norra Kärr.”
