After Congress lifted a Biden-era mining ban near the pristine wilderness, advocates are turning to Gov. Tim Walz to halt permitting of the proposed mines. The lifting of the federal ban has opened the door for new mining projects in the Boundary Waters region, prompting environmental groups and tribal leaders to seek state intervention. Officials say the state will review the proposals in light of the new federal stance and local environmental priorities. Looking ahead, stakeholders anticipate a careful assessment of the mines' environmental footprint before any permits are granted.
