The City of Duparquet and First Mining Gold Corp. (TSX: FF) (OTCQX: FFMGF) (FRANKFURT: FMG) are pleased to announce the signing of a Memorandum of Understanding aimed at formalizing a mutually beneficial and collaborative relationship towards the development of the Duparquet Gold Project hand in hand with addressing important community development needs. This MOU, ratified by the municipal council on September 15, 2025, represents a significant milestone as it notably delivers to the City land to support sustainable community development in harmony with potential future mine development.

Since acquiring the project in 2022, First Mining has expressed its commitment to working closely with the City and citizens of Duparquet. As early as 2023, constructive dialogue began to find sustainable solutions related to future development synergies between the City and the Project. These discussions have resulted in a common framework for advancing the Project and municipal development, now formalized by the signing of this MOU.

Key Measures in the MOU include:

• The development of a co-habitation plan for the development of the Project and the updating of the City’s urban development plan in consideration of the Project
• A mechanism to address the relocation of certain residential properties required for the development of the Project
• The development of a design plan for the reconfiguration of the Duparquet golf course as required for the development of the Project
• The provision by First Mining to transfer over 100 acres of land to the City for near-term municipal development needs and potential additional lands in the future
• The transfer by First Mining of the residential lots held under historical emphyteutic leases located within the City and outside of the Project development area

A Milestone for the Community and First Mining

“This agreement demonstrates First Mining’s commitment to working with the City and citizens supporting the City’s sustainable development in concrete ways as we advance the Duparquet Gold Project. We want to build a mining project rooted in respect, transparency, and mutual benefit aligned with Duparquet’s own development objectives,” said Dan Wilton, CEO of First Mining.

Denis Blais, Mayor of the City of Duparquet, commented, “The signing of this MOU is a historic moment for our municipality. It illustrates our determination to advance the interests of our community while creating the conditions for harmonious economic development, prosperity and well-being for current and future generations. First Mining’s approach in working collaboratively with the City from the beginning as the new Project owner and its on-going commitment through the agreement is both positive and meaningful.”

About the City of Duparquet

About 700 residents live in the City of Duparquet, located in the Abitibi-Témiscamingue administrative region, on a territory spanning more than 157 square kilometers. Duparquet lies at the southern edge of the Abitibi-Ouest Regional County Municipality, near the city of Rouyn-Noranda. It obtained its city charter in 1933, becoming the first municipality officially incorporated in Abitibi-Ouest. The city was founded in the early 1930s, when mining activities began to develop the region’s rich underground resources. In 1933, with the opening of the Beattie Gold Mine, dozens of houses were built and the community grew rapidly. The city was named in honor of a captain of the grenadiers of the Régiment de la Sarre, who was wounded at the Battle of Sainte-Foy. The mine’s opening sparked a significant demographic and architectural boom, traces of which remain today in the “Boomtown”-style façades still visible on some of the town’s buildings.
