The Biden administration has shown they're ready to take bold action to protect our country's most special places, so we're kicking off 100 Days of Action to Save the Boundary Waters to make sure America’s most visited Wilderness is at the top of the list.  

"100 days of Action to Save the Boundary Waters" is a multi-week campaign to demonstrate the overwhelming support to protect the Boundary Waters Canoe Area Wilderness from the threat of sulfide-ore copper mining. Each week we will be sharing information around specific themes about the issue of sulfide-ore copper mining on the edge of the Wilderness and asking you to take specific action towards protecting the Wilderness. There will be opportunities to learn more about the issue and to test your existing knowledge.

Nearly 70% of Minnesotans support permanent protection for the Boundary Waters. Are you one of them? Join the fight by taking the pledge to protect the Boundary Waters for future generations.

Sulfide-ore copper mining will cause irreversible environmental damage to the Boundary Waters. Dozens of scientific analyses have shown that hardrock mining on the Boundary Waters’ doorstep will cause irreparable harm to this irreplaceable Wilderness. A few of the most important scientific findings include:

  • The Environmental Protection Agency (EPA) has deemed metal mining as the United States’ most toxic industry. 

  • Pollution from these mines will inevitably flow directly into the heart of the Boundary Waters.

  • Because of the Boundary Waters’ interconnected groundwater, wetlands, and abundant lakes and streams, the area is especially vulnerable. 

  • Acid mine drainage could wipe out local fish species. Heavy metals and associated pollutants from sulfide-ore copper mines harm microorganisms, aquatic plants, and fish.


The Boundary Waters Canoe Area Wilderness is threatened by proposed sulfide-ore copper mining. Chilean mining conglomerate Antofagasta's Twin Metals project was terminated in 2016 by the US Forest Service because it posed a threat of irreparable harm to an irreplaceable Wilderness. It was resurrected by the Trump administration and was being fast-tracked through inadequate reviews and negative changes to bedrock environmental laws. 

2021 is our best chance to permanently protect the Boundary Waters. We continue to work on several fronts focused on permanently prohibiting sulfide-ore mining in the Boundary Waters watershed. Our path to permanent protection includes re-initiating a federal mineral withdrawal, passing a permanent protection bill in Congress and the MN legislature, ongoing litigation to terminate the unlawful leases, using science to push back against the proposed mine plan and revising the state's rules regulating mining.
