The U.S. Forest Service is considering denial of Twin Metals' request to renew expired federal mineral leases for development of sulfide mining on tribal Ceded Territories near the Boundary Waters Canoe Area Wilderness.
It’s crucial that we seize this opportunity tell the Forest Service that sulfide mining poses unacceptable risks to Minnesota water resources and communities. Please sign and share this petition calling upon the Forest Service to protect the Boundary Waters and tribal resources by denying renewal of Twin Metals’ leases for toxic copper-nickel mining.
