Power Transmission Line for the Sustainable Development of the Bégin-Lamarche Phosphate Deposit

First Phosphate will conduct a study to confirm the viability of clean energy infrastructure, including site selection and the identification of connection corridors, a feasibility study, and the design of a 161-kV transmission line and substations in the Saguenay-Lac-Saint-Jean region. The Project will include technical analyses, cost estimates, environmental studies, and public and Indigenous consultation. The total non-repayable contribution for this project will be approximately $3.07 million.

Road Infrastructure for the Responsible Development of the Bégin-Lamarche Phosphate Deposit

First Phosphate will carry out the preparatory work necessary for the construction of a new access road and will identify the preferred option for upgrading bypass roads to support transportation between the Bégin-Lamarche phosphate mine and regional infrastructure, including rail links and the Port of Saguenay. The Project will include pre-feasibility and feasibility studies (technical, environmental, and economic), design of the work, required environmental studies, as well as a traffic analysis and public and indigenous consultation. The total non-repayable contribution for this project will be approximately $1.77 million.

"Canada has what the world wants, and we are building the infrastructure required to get those resources to diverse markets," said the Honourable Tim Hodgson, Minister of Energy and Natural Resources. "Investments like these help unlock our full potential by connecting projects to the infrastructure they need to move forward - creating jobs, strengthening supply chains and delivering lasting prosperity for Quebec and Canada."

"Canada and Quebec have an opportunity to become a reliable supplier of the critical minerals the world needs for the technologies and industries of the future," said Claude Guay, Parliamentary Secretary to the Minister of Energy and Natural Resources. "We are supporting critical minerals projects in Saguenay-Lac-Saint-Jean and beyond to strengthen Canadian supply chains, create economic opportunities, and build Canada Strong."
