FIRST MINING PROVIDES UPDATE ON SPRINGPOLE GOLD PROJECT

Following discussions with the Impact Assessment Agency of Canada, First Mining Gold Corp. has voluntarily agreed to a short extension to the environmental assessment decision date on the Springpole gold project until June 30, 2026. The original IAAC decision date on the Springpole project was May 22, 2026, and the extension will provide IAAC additional time to complete the final EA report.

First Mining is pleased to announce that the Cat Lake and Lac Seul first nations have completed their independent Anishinaabe-led impact assessment on the Springpole project, supported by First Mining. The communities are preparing to vote, based on the findings of the ALIA, on June 4, 2026. The short extension will allow the communities to continue working with the provincial and federal government to achieve the necessary measures to ensure they can meaningfully participate in the project.
