Minnesota lawmakers propose ban and moratorium on copper mining

Efforts to slow copper-mining's advance into Minnesota are intensifying, with state lawmakers proposing a prohibitive measure that would require mining companies to show proof that a similar non-iron, hard-rock mine has operated safely elsewhere.

More is in the works, including companion state and federal bills to ban copper mining on federal lands next to the Boundary Waters Canoe Area Wilderness.

Those are slated to be introduced shortly in Minnesota and Congress. Such bans would kill the proposed Twin Metals copper mine that Chilean mining giant Antofagasta wants to build.
