Exploratory drilling for copper deposits is taking place at an Upper Peninsula park.
Drilling for possible copper deposits is taking place at Porcupine Mountains Wilderness State Park.
The DNR issued a permit to Highland Copper subsidiary, Orvana Resources to conduct the drilling on a 1-mile-square piece along the park’s west edge.
If the results show the potential for enough copper, a feasibility study will be conducted.
The study would be designed to mine deposits by underground methods.
