Should states mandate comprehensive environmental reviews before approving new mining projects?

Tribal leaders from the Grand Portage and Bois Forte Bands have petitioned the state for an environmental review of mining activities across 1854 Treaty land. The groups also requested a regulatory moratorium on new mining permits until the study concludes.

Why it matters

Tribes cite cumulative damage from industrial mining and its role in the decline of wild rice, a staple central to Ojibwe culture. They argue that an updated assessment is necessary to protect water quality and historical land rights.

The requested assessment spans 5.5 million acres of land ceded by tribes more than 170 years ago. Current projects under review include mining plans near the Boundary Waters Canoe Area Wilderness and the Iron Range.

The players

Grand Portage Band

This is a federally recognized Ojibwe tribe located in northeastern Minnesota.

Bois Forte Band

This is a band of Lake Superior Chippewa that maintains sovereign land and interests in Minnesota.

Minnesota Environmental Quality Board

This state agency coordinates environmental review processes and policy development for the state of Minnesota.

NewRange Copper Nickel

This is a mining firm currently pursuing copper-nickel projects in the Hoyt Lakes area of Minnesota.

Twin Metals

This company is a subsidiary of Antofagasta PLC that is seeking permits for mining operations near the Boundary Waters.

The details

Leaders aim to address the accumulation of mining waste, specifically sulfate, which they identify as a primary cause for the disappearance of wild rice from local lakes. The proposal seeks to halt new permitting processes for companies like NewRange Copper Nickel and Twin Metals while the comprehensive study is underway.

More than 170 years ago, tribes ceded the 5.5 million acres of treaty land.
On September 23, 2026, tribal leaders announced the request during a panel.

Roadmap

This request highlights the ongoing tension between Minnesota's industrial mining legacy and the expansion of modern copper-nickel projects. It reflects a broader shift toward tighter environmental scrutiny for natural resource extraction on indigenous lands.

The potential moratorium on new permits could significantly shift the timeline for planned mining developments in the Iron Range. Residents may see changes to regional land-use policies if the state board approves the formal environmental assessment.

The takeaway

The move underscores the growing role of tribal environmental advocacy in shaping state industrial policy. Leaders emphasize that sustainable water management is vital for the long-term health of both local ecosystems and indigenous cultural identity.
