The state is reviewing a proposal by a Canada-based supplier of lime and limestone products to acquire more than 10,000 acres of state-managed forest Michigan's Upper Peninsula for use as a mine.
Graymont Inc.'s plan outlined Thursday includes the acquisition of about 7,820 acres for an underground limestone mine; about 1,780 acres for two surface mines; and an option to purchase 840 acres for the potential development of a limestone processing plant.
The project would be in Mackinac County. The company plans a public meeting Tuesday in Hudson Township.
Plans call for the DNR to keep a state-managed surface easement on all but 1,500 acres of the underground mine portion so property would continue to be managed for timber and open for recreational uses such as hunting, hiking and snowmobiling.
