Val-D'Or Mining Signs Exploration Agreement with the Matachewan First Nation and Mattagami First Nation

Val-D'Or Mining Corporation (TSXV: VZZ) (OTCQB: VDOMF) ("Val-D'Or Mining" or "the Company") is pleased to announce the signing of a milestone Exploration Agreement dated October 15, 2025 (the "Exploration Agreement") with the Matachewan First Nation (Matachewan FN) and Mattagami First Nation (Mattagami FN), members within the Wabun Tribal Council (WTC). The Exploration Agreement was signed by the three companies within the "Zed Zed Group": Val-D'Or Mining, Cleghorn Minerals Ltd., and International Prospect Ventures Ltd. The Exploration Agreement covers the Company's Operational Areas of Interest ("the Properties") within the First Nations' traditional lands, located in northeastern Ontario's Abitibi Greenstone Belt.

The Exploration Agreement outlines the terms on how consultation and impact mitigation on exploration activities will be conducted. It also delivers financial benefits, including contracts, jobs, and training opportunities during the exploration phase, for both current and future work programs across the property portfolio covered by the Exploration Agreement. Further, the Exploration Agreement provides that the Company will, subject to the approval of the TSX Venture Exchange, issue to each of Matachewan FN and Mattagami FN 50,000 common shares of the Company, and will also grant to each of Matachewan FN and Mattagami FN incentive stock options to acquire 50,000 shares of the Company at a per share price of $0.085 for a period of five years from issuance, in accordance with its incentive stock option plan and a consulting agreement among the parties. The Exploration Agreement will remain in effect until such time that an Impact Benefit Agreement (IBA) has been concluded.

Michael Rosatelli, Senior Geological Consultant and Vice President Exploration of Val-D'Or Mining commented: "I'm deeply honoured to be part of this historic milestone, which stands as a powerful testament to what can be achieved when we unite around a shared vision. I extend my gratitude to Chief Batisse of the Matachewan First Nation and Chief Constant of the Mattagami First Nation, along with their respective Councils, the negotiating committee led by their Mineral Development Advisors, the Wabun Tribal Council, and the local community members. Your unwavering commitment, thoughtful collaboration, and dedication to fostering this agreement, grounded in mutual respect and attentive listening to the voices of elders and individual community members, have been truly inspiring."

This milestone represents the culmination of more than five years of relationship-building and dialogue between the Company and the Matachewan and Mattagami First Nations, and the Wabun Tribal Council, and establishes a strong foundation for on-going cooperation among all parties.

The Matachewan First Nation has provided a Support Letter to the Ontario Ministry of Mines endorsing the maiden drill program on the Company's Baden Prospect (see Val-D'Or Mining's October 21, 2025 press release), prior to permit issuance.

Val-D'Or Mining, and its joint venture partners, remain committed to responsible exploration and to delivering shared economic opportunities to the local communities. An official signing ceremony will be held at the Wabun Tribal Council offices in Timmins, Ontario. Details will be announced once confirmed.
