Leading Edge Materials advances midstream processing at Norra Kärr

LEADING EDGE MATERIALS ADVANCES MIDSTREAM PROCESSING STRATEGY FOR THE NORRA KÄRR HEAVY RARE EARTH ELEMENTS PROJECT

LEADING EDGE MATERIALS ADVANCES MIDSTREAM PROCESSING STRATEGY FOR THE NORRA KÄRR HEAVY RARE EARTH ELEMENTS PROJECT

Initiative launched to enhance Norra Kärr’s flowsheet with collaboration on new hydrometallurgical research in support of future pilot plant establishment.

Swedish Government funding secured: two projects involving the company awarded funding through Vinnova, the Swedish Innovation agency, as part of a SEK 70+ million (CAD 10 million) national push to secure Sweden's critical raw materials supply.

Path to concentrate production: Domain sampling now underway to generate high-grade eudialyte concentrate, the essential feedstock for upcoming hydrometallurgical pilot testing.

On track to develop the EU’s first heavy rare earth elements mine following the grant of Norra Kärr’s 25-year mining lease in June 2026

Vancouver, July 20,2 026 - Leading Edge Materials Corp. ("Leading Edge Materials" or the "Company") (TSXV: LEM) (Nasdaq First North: LEMSE) (OTCQB: LEMIF) (FRA: 7FL) is pleased to provide an update on its midstream processing strategy for eudialyte concentrate from the Norra Kärr Heavy Rare Earth Elements ("HREE") Project – and the path toward pilot-scale hydrometallurgical testing, a key step in demonstrating the process at commercial scale. This builds on the significant flowsheet development work completed over the last 15 years, and new research into silicate management under the Vinnova-funded SHLENK project.

Eudialyte Processing

Eudialyte is recognised globally as one of the most promising mineral sources of heavy rare earth elements, with projects in Greenland and Australia being developed in addition to Norra Kärr in Sweden. With eudialyte, the behaviour of silicates during leaching needs to be managed to prevent gel formation. Two well-known approaches are dilution, reducing silicate concentrations through sufficient dilution during leaching and inhibiting gel formation, and pre-treatment, treating the eudialyte concentrate ahead of leaching to prevent silicate release during dissolution, while preserving rare earth element solubility. Studies have demonstrated that under correctly selected pretreatment conditions for a given source material, silicate leaching can be effectively prevented. The pre-treatment option was used in the Company's 2021 Preliminary Economic Assessment ("PEA") and current project development workstreams are focused on performance and cost optimisation, and upscaling studies.

Pilot-Scale Hydrometallurgical Testing

The pre-treatment approach has shown strong results in laboratory-scale testing for Norra Kärr material and an extended pilot is intended to further strengthen hydrometallurgical understanding. To achieve optimal pilot data, a new high-grade eudialyte concentrate will be produced. Over the summer, the Company is conducting a domain sampling programme using the existing drill core library. This will be followed by further mineral processing to produce eudialyte concentrate while also generating valuable nepheline syenite as co-product for customer trials.

Consistent with the design set out in the Company’s 2021 PEA, mineral processing at Norra Kärr will only feature crushing, grinding, and magnetic separation; the eudialyte concentrate would then be transported to a midstream hydrometallurgical facility at a separate, established industrial location – keeping the footprint at Norra Kärr small and placing chemical processing where infrastructure already exists.

New Innovation Research: The SHLENK Project

The pilot work programme will benefit from research into improved processing methods, including through the Company's collaboration with RISE (Research Institutes of Sweden) under the SEK 1.5 million (CAD 0.2 million) funded SHLENK project – "Silicate management in leaching of eudialyte from Norra Kärr”.

SHLENK is one of two research projects involving the Company’s wholly owned Swedish subsidiary, Greenna Mineral AB, that have recently been granted funding by the Swedish Government through Vinnova's Impact Innovation call, "Resilient metals and minerals supply for strengthened preparedness," alongside the NordAL (Nordic Alumina) project.

Together with 17 other projects, these initiatives form part of a national effort to strengthen Sweden's metals and minerals supply chain in peacetime, during heightened preparedness, and in times of crisis. The combined programme represents more than SEK 70 million (approximately CAD 10 million) in funding, of which approximately SEK 42 million (CAD 6 million) is provided by Vinnova.

For the Company, this funding represents strong recognition of the strategic importance of its work at Norra Kärr and its contribution to building a more resilient and secure supply chain for critical raw materials in Sweden and the Nordics.

The work is carried out within Swedish Metals & Minerals, a joint initiative by the Swedish Energy Agency, Formas, and Vinnova under the framework of Impact Innovation.

Kurt Budge, Chief Executive Officer, commented:

“Following the grant of the 25-year mining lease, our work continues towards developing Norra Kärr, the EU's first heavy rare earth elements mine.

Progressing with our Pre-feasibility Study, we continue to de-risk and enhance the processing flowsheet for Norra Kärr. We have a clear plan: working with the best eudialyte concentrate, verifying our pre-treatment approach to silicate management, and generating the data we need to run at pilot scale.

Heavy rare earths like dysprosium and terbium are foundational to the technologies driving electrification and defence readiness across Europe, and Norra Kärr remains one of the continent's richest deposits. The support from Vinnova is a strong validation of the strategic role Norra Kärr can play in strengthening Sweden's and Europe's resilience in critical raw materials."

About the Norra Kärr Project

Norra Kärr is one of Europe's most significant deposits of heavy rare earth elements, hosted in an eudialyte-bearing alkaline rock body in southern Sweden. The project's strategic value is underpinned by its high dysprosium and terbium ("Dy/Tb") content, critical inputs for permanent magnets used in electric vehicles, wind turbines, and defence applications.

On 28 June 2026, an Exploitation Concession – 25-year mining lease - was granted by the Swedish Government following a formal recommendation from the Mining Inspectorate ( Sw. Bergsstaten ), which submitted the application to the Government for a final decision after all involved agencies had either endorsed the application or recommended approval.

The strategic importance of heavy rare earth elements to Europe's industrial future has never been more apparent. As China's export controls have demonstrated, access to dysprosium, terbium and yttrium cannot be taken for granted — and the consequences of supply disruption are severe. Norra Kärr, now holding an Exploitation Concession, is key to addressing Europe’s critical risk exposure.

Edison estimates current European dysprosium demand at 180-200 tpa of Dy₂O₃. Norra Kärr's 2021 PEA discloses average annual Dy₂O₃ production of 248t, which Edison notes is "similar to European consumption."
