Far-sighted Vision
Since the 1900s, a diverse cast — politicians, local businesses, recreationists, and yes, even lawyers — recognized the need to protect this wilderness.

The Twin Metals Mine — a proposed sulfide-ore copper mine sited at the headwaters of the Boundary Waters — threatens to permanently destroy this thriving biodiverse ecosystem.

1 / 3

Unprecedented Risk

Sulfide-ore mining has never been done before in Minnesota — and it has never been done safely anywhere.

2 / 3

Permanent Damage

Sulfide-ore mining is inherently dangerous because it produces sulfuric acid, which can irreversibly contaminate the rivers and streams flowing into the Boundary Waters.

Superfund Sites

“Sulfide mining is risky on its own,” explains Adam Ratchenski, attorney in Earthjustice’s Midwest Office. “There are Superfund sites all around the country to show that.”

The Twin Metals Mine site lays on the edge of the Boundary Waters wilderness.

Though Ely has a long history of mining — even helping Minnesota supply the bulk of iron to the U.S. in World War II — sulfide mining has never before been allowed in the state.

What’s Happening Now

This June, the Trump administration announced its intent to withdraw a 20-year mining ban that protects the headwaters of the Boundary Waters.

Your voice is needed! We still have a chance to save the Boundary Waters now and for future generations. Tell the Interior Department that you support the mining ban that protects the Boundary Waters.
