IAAC analyzes Valentine gold project changes, calls for public comments

The Impact Assessment Agency of Canada (IAAC) has launched a public comment period on proposed amendments to the Valentine gold project in Newfoundland and Labrador. The open-pit gold mine, located approximately 55 km southwest of Millertown, is seeking changes to its original project plan.

This public comment period represents a crucial opportunity for stakeholders to provide input on the evolving plans for one of Atlantic Canada's most significant mining projects. The IAAC encourages all interested parties to participate and share their perspectives on the proposed amendments to the Valentine gold project.

Marathon Gold, the project's proponent, has proposed modifications related to ore management, water infrastructure, fuel storage, and site layout. These changes include expansions to the workers' camp, laydown areas, and process plant pad.

The IAAC's preliminary analysis suggests these alterations would not result in significant adverse effects beyond those identified in the original 2022 environmental assessment report. However, the agency is seeking public input on its draft analysis and proposed amendments to the project's decision statement.

The Valentine gold project, when operational, is expected to be the largest gold mine in Atlantic Canada, with an estimated annual production of 173,000 ounces of gold and a mine life of 13 years.

The IAAC invites Indigenous peoples and the public to review and comment on the proposed changes. Participants can submit feedback online through the Canadian Impact Assessment Registry (reference number 80140) until 11:59 p.m. on January 30, 2026. Comments should focus on the analysis of proposed changes and modifications to the decision statement. It's important to note that the original decision itself cannot be amended through this process.

For those who prefer alternative submission formats, arrangements can be made by contacting conditions@iaac-aeic.gc.ca. All comments will be published online as part of the project file.

Relevant documents, including the IAAC's draft analysis report and the proponent's submission, are available on the Registry. For more information on the post-decision phase, interested parties can visit the IAAC's website at canada.ca/iaac.
