The KSM Project is in the coastal mountains of northwest British Columbia, approximately 65 km from Stewart, BC and 35 km northeast of the BC – Alaska border. The proposed mine site is located in the upper geographical reaches of Sulphurets and Mitchell creeks, tributaries of the transboundary Unuk River, which flows into the Pacific Ocean through Alaska. Due to the deposit location, concerns of Alaskans along with the potential impacts to Alaskan waters were an important focus and carefully evaluated during the environmental assessment.
"The agency has concluded that no significant adverse impacts on water quality, water quantity, fish, or human health are expected on the Alaskan side of the Unuk River"
Canadian Environmental Assessment Agency’s scientific report
The Seabridge team engaged vigorously and extensively with Alaskan regulators and stakeholders throughout the environmental assessment review and permitting phases of the KSM Project to ensure that downstream waters in Alaska would not be impacted by the proposed KSM operations.
To gain deeper insight into the BC Government and the mining sector’s efforts to protect transboundary watersheds, the robust, science-driven laws and regulations that govern BC’s mining industry and other pertaining facts about the industry you can also visit the Mining in the Transboundary Region page on the Mining Association of British Columbia’s website.
The involvement of Alaskan regulators was documented in a 2014 Juneau Empire article which summarized the conclusions of these regulators, “four of the same resource managers and specialists who reviewed Alaskan mines have examined KSM’s plan. They found no significant issues with the application.”
