Canada’s KSM Mine Jeopardizes Southeast Alaskan Communities and Regional Economy, with No Benefit to Alaska


The construction and operation of the KSM Mine in British Columbia, at the headwaters of the Unuk River 19 miles from the Alaskan border, could jeopardize the health and well-being of Southeast Alaskan communities and our regional economy. 

Clean water and salmon fuel Southeast Alaska’s $2 billion/year fishing and tourism economy, sustain our communities, and are integral to our cultural practices. As one of the world’s largest open-pit mines, the proposed KSM could permanently transform the upper Unuk and Nass Rivers, filling entire tributaries of these salmon strongholds with billions of tons of acid-generating rock. The massive scale and untested mitigation measures of the KSM proposal put downstream water quality, salmon, and communities at risk, and would require water treatment for at least 250 years, if not forever, to protect the Unuk.

A number of communities throughout Southeast Alaska have already spoken out against the KSM project because of the harm it could cause them. Thus far, the BC government has proven incapable of monitoring and enforcement over the mining industry. 

Let’s work together to protect the Unuk River.
