What happened

The Senate on Thursday overturned a mining moratorium in Minnesota's Superior National Forest, a boon for a Chilean mining company subsidiary and a stinging loss for environmentalists trying to protect the Boundary Waters Canoe Area Wilderness.

Why it matters

The chamber voted 50-49 to overturn a protection imposed by President Joe Biden in 2023 that he set for 20 years.

Common ground

It clears the way for a long-stalled mine project proposed by Twin Metals Minnesota to restart plans to access the immense stores of copper and other minerals in the Superior National Forest near the Boundary Waters.

Perspective signals
