Twin Metals Proposes Copper Sulfide Mine

WBUR Boston Duluth 17d17d Impact 5

Twin Metals, a subsidiary of the Chilean company Antofagasta, has proposed mining operations in the Boundary Waters Canoe Area Wilderness. The proposal targets a region known for its wildlife and crystal clear waters. The state is currently the largest producer of iron ore in the United States. The proposed copper sulfide mine is located near Birch Lake, which connects to the Boundary Waters watershed. Concerns exist regarding potential pollution flowing hundreds of miles through the water system. The mine is described as being on the doorstep of the Boundary Waters rather than directly within it. Mining operations could turn water and ground into sulfuric acid, potentially impacting the watershed. Mining companies claim they have containment methods to protect the area, but critics argue these protections often fail in practice.

Mining companies claim they have containment methods to protect the area, but critics argue these protections often fail in practice. The proposal involves land adjacent to the Superior National Forest. The Minnesota Chippewa tribes have expressed strong opposition based on the 1854 Treaty of La Pointe. This treaty protects ancestral lands and treaty rights of the Anishinaabe tribes. Activists intend to remain mobilized to influence state-level permits and mining operation plans.

“The Boundary Waters Canoe Area Wilderness in Minnesota protects over a million acres on the U.S.-Canada border that's teeming with wildlife and crystal clear waters. But the region is rich in copper and other minerals, which Twin Metals, a subsidiary of the Chilean company Antofagasta has proposed to mine.”

WBUR Boston

“This mine is unique because it is a copper sulfide mine, which is a very dangerous and polluting.”

WBUR Boston

“This mine is not in the boundary waters but it is on the doorstep of the boundary waters. It is extremely close to this lake called Birch Lake that connects to the boundary waters.”

“what happens is it basically turns into sulfuric acid like battery acid and what happens is then of course that there's that hundreds of millions of tons of rocks.”

WBUR Boston

“The Superior National Forest, which is right next to the Boundary Waters and the Boundary Waters itself, are all part of the land that is covered by the 1854 Treaty of La Pointe.”

WBUR Boston

“at the federal level, there also will be an environmental impact statement. to protect boundary waters from mining. I think that what will happen next is that people are going to stay mobilized on this.”
