MISHKEEGOGAMANG FIRST NATION AND FIRST MINING SIGN LONG TERM RELATIONSHIP AGREEMENT FOR THE DEVELOPMENT OF THE SPRINGPOLE GOLD PROJECT

Mishkeegogamang First Nation and First Mining Gold Corp. have signed a long-term relationship agreement (LTRA), covering the Springpole gold project, located in Northwestern Ontario. The agreement sets out a collaborative approach for the development of one of Canada's largest gold resources, through construction, operations and closure, in a manner that respects the environment and provides direct benefits to the first nation.

Merle Loon, chief of Mishkeegogamang First Nation, stated:

"This agreement is the result of a five-year process of technical review, traditional knowledge study and relationship building with First Mining. The agreement ensures that Mishkeegogamang's interests will be represented in the development and operation of the Springpole project, and will deliver long-term value by creating concrete opportunities for our community and our members. Together with First Mining, we are shaping the direction of a modern and long-term collaboration that is in keeping with our values."

Dan Wilton, chief executive officer of First Mining, stated:

"I would like to thank the Mishkeegogamang community and their leadership for the many years of hard work that they have put into information sharing, understanding and helping us shape and improve the plans for Springpole. This modern agreement provides clear avenues for Mishkeegogamang's participation in the development and operation of the project from an environmental, cultural, economic and business opportunities perspective. We thank the leadership of Mishkeegogmang for their openness, collaboration and trust, and look forward to continuing to advance the project as long-term partners."

Following a process agreement signed in 2021 between Mishkeegogamang and First Mining, the LTRA was negotiated along with a community-based consultation process to ensure that the interests and concerns of the first nation were taken into account. The LTRA includes provisions for Mishkeegogamang to take part in the project's environmental management and monitoring, the implementation of adaptive management and preferential training and employability measures, equity and participation in the economic upside of the project, the promotion of business opportunities during the mine's construction and operations, as well as the recognition of Anishnaabe culture and the inclusion of cultural safety measures. The LTRA also sets out the sharing of financial benefits from the Springpole project.
