• Nonmetallic Minerals
Part 5, Section 502, Act 451, Public Acts of 1994, as amended, authorizes the Michigan Department of Natural Resources to enter into contracts for the Nonmetallic Minerals Leasing Program.

• Terms of the Nonmetallic Mineral Leases
The nonmetallic mineral leases have a minimum production royalty rate instead of rentals and minimum bid rates.  Bidding for the leases is based upon the highest royalty rate per ton of material removed.  The basic term of the lease is 7 years with the possibility of extending it to 10 years if it is in the best interest of the State to do so. Leases were developed for Construction Sand, Gravel, Cobbles, Boulders, Clay; Salt/Potash, and Limestone/Dolomite.

The maximum lease size is 640 acres.  There are 35,308 acres under 174 State Nonmetallic Minerals Leases (March 2011).

The production of nonmetallic minerals continues to have an important role in Michigan's statewide mineral production activity.  Michigan ranks near the top in the U.S. for the value of the nonmetallic minerals produced.  The production of nonmetallic minerals from State-owned land continues to be an important source of locally utilized materials for road and other construction purposes.
