New rules approved by the Wisconsin Department of Natural Resources mean companies applying for a nonferrous mining permit would have to pay an additional half-million dollars. Applicants would have to pay more for permits and licenses while turning in more detailed plans to the D-N-R. The list of new rules also includes new areas where mining wouldn’t be allowed – like wilderness areas, wild and scenic rivers, national and state parks, wildlife refuges, and endangered species habitat. The new rules were approved unanimously Wednesday. Not much mining is conducted in Wisconsin these days, but companies looking for copper, gold, and silver would have to make a much-larger investment before removing minerals from the ground.
