Canadian company wants to buy Mackinac County forestland for limestone mining

A Canadian company has asked the Michigan DNR to sell it more than 10,000 acres of state forestland in Mackinac County. Graymont, Incorporated wants to develop a limestone mine on the land in northern Mackinac County near Rexton.

The company first approached the DNR about a sale two years ago and explored the area for limestone in 2012 and 2013. The DNR is processing and reviewing Graymont’s application.

DNR staff will make a recommendation to DNR Director Keith Creagh, who has the authority to make the final decision. Creagh will make his decision at an unspecified future Natural Resources Commission meeting.

The DNR has more information about the project online here, and it’s also accepting public comments via email at
