First Mining Receives Federal Approval for the Springpole Gold Project Environmental Assessment

First Mining Gold Corp. announced on June 30, 2026, that it received Federal Environmental Assessment (EA) approval for its Springpole Gold Project in Ontario, Canada. The approval, issued by the Federal Minister of the Environment, allows the project to proceed to the post-EA phase of engineering designs and construction readiness, subject to specific environmental mitigation conditions.

Concurrently, the company entered into a Term Sheet Agreement with Slate Falls Nation to negotiate a final Project Agreement, outlining development parameters, regulatory collaboration, and financial participation mechanisms. This follows earlier authorizations from Cat Lake First Nation and Lac Seul First Nation on June 16, 2026, and a $4 million commitment to fund an all-season access road with Cat Lake.

The Springpole project is currently at the Pre-Feasibility Study (PFS) stage, with a technical report filed in December 2025 projecting a $1.1 billion initial capital cost and a 9.4-year mine life.

First Mining Gold Corp. (FF) received federal environmental assessment approval for its Springpole project, a regulatory milestone that validates the company’s Indigenous engagement and environmental strategy. The approval removes a significant bottleneck, allowing the company to advance engineering optimizations and begin preliminary construction planning. However, the decision does not immediately impact cash flow or alter the project’s substantial $1.1 billion capital requirement.

The environmental assessment decision was scheduled for June 30, 2026, meaning the approval falls within the expected permitting timeline. First Mining’s stock has been consolidating around $0.66, down from a January 2026 high of $0.80, suggesting the market has already priced in this anticipated milestone.

First Mining Gold Corp. is a Canadian exploration and development company focused on gold and silver assets. Its flagship asset is the 100%-owned Springpole Gold Project, located 110 km northeast of Red Lake in Ontario. The project is currently in the pre-feasibility study (PFS) stage.

According to the PFS dated December 2025, Springpole is designed as a 30,000 tonnes per day open-pit operation with a 9.4-year mine life. The plan calls for an average annual production of 330,000 ounces of gold during years one through five. The study projects a pre-tax net present value of $3.2 billion at a gold price of $3,100 per ounce, based on a 5% discount rate. The project carries a life-of-mine all-in sustaining cost (AISC) of $938 per ounce and requires an initial capital expenditure of $1.1 billion.

The company also holds the Duparquet Gold Project in Quebec, which is in the preliminary economic assessment (PEA) stage. The project contains a measured and indicated resource of 3.44 million ounces. A 2026 drilling program is planned to target 12,000 meters to expand the Miroir and other targets.

First Mining Gold maintains a 20% joint venture interest in the Pickle Crow Gold Project through PC Gold Inc. and holds a 48% stake in Seva Mining Corp., which operates the Cameron Gold Project.
