CABs ENDORSE NORRA KARR MINING LEASE APPLICATION

CABs ENDORSE NORRA KÄRR MINING LEASE APPLICATION

Vancouver, December 3, 2025 – 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 County Administrative Boards (“CABs”) of Jönköping and Östergötland endorse (Sw. Tillstyrker) the Company’s wholly-owned Swedish subsidiary Greenna Minerals AB’s application for an Exploitation Concession – 25-year mining lease (Sw. Bearbetningskoncession) - for Norra Kärr. This step forward precedes a final decision on the application by the Mining Inspectorate (Sw. Bergsstaten).

In the permit process to open a mine in Sweden, the CAB is a mandatory consultation party in reviewing the application. Since the Norra Kärr deposit crosses county lines, there are two CABs submitting their written opinions – the counties of Jönköping and Östergötland. If the Mining Inspectorate and the CAB in question disagree about an application, it is then transferred to the government for a final decision. But now, with the endorsement of the CABs, the decision will be made by the Mining Inspectorate.

Kurt Budge CEO comments:

“This is a major step towards efficient permitting of Norra Kärr. While it should be pointed out that this is not a formal permitting decision, it is a significant consultation opinion that says that we have done what we are required to do in this phase of permitting. I am happy to see that we have been compliant with all permitting procedures and have been able to address the CABs requirements for information. Importantly, it also means that the application will not be subject to a decision by the Swedish government.

It's a credit to the Swedish technical, legal, sustainability and stakeholder engagement teams, that have worked on Norra Kärr over many years to potentially be granted an Exploitation Concession; that would in turn grant us exclusive rights to develop the deposit over a 25-year period. In the next phase of permitting, an environmental permit will need to be granted. Within that, every question regarding environmental impact, including water, will be comprehensively addressed.

On behalf of the Board of Directors,
Leading Edge Materials Corp.
