Clean Water. Strong Minnesota. Stop PolyMet/Glencore.

Why do we oppose the proposed PolyMet/Glencore mine and dam?



Sulfide mine dam spills in the US and around the world have released carcinogens, neurotoxins, and heavy metals into drinking water. The Minnesota DNR declined to conduct a Health Impact Assessment, so downstream communities do not currently know how this project would affect our health.



The proposed PolyMet waste storage dam would not use best practices or technology. PolyMet’s proposal is for an above ground, open pit of wet tailings with a cascading dam wall, which would require water treatment for centuries. The international community, experts inside and outside of sulfide mine companies, and the UN have warned against using these designs.

Our river and our lake

We cannot express how much the St. Louis River and Lake Superior means to those of us enough lucky enough to live here: for our economy, for spirituality, and for our way of life. Toxic spills from the proposed PolyMet mine and dam would flow into the Partridge and Embarrass Rivers, which flow into the St. Louis River, one of the largest tributaries of Lake Superior.

It’s time to move on to a better safer alternative for Minnesota. Please stand with us in defense of clean water.
