Over the last five years, they have gone out of their way to visit with us and to explain the project and its impact on us. It is clear to us that Seabridge is committed to the community, to First Nations and to the Gitxsan people. We believe the KSM project will bring jobs and economic benefits to our people and communities, for the life of the mine and beyond.
