The commissioner may issue leases to prospect for, mine, and remove minerals other than iron ore upon any lands owned by the state, including trust fund lands, lands forfeited for nonpayment of taxes whether held in trust or otherwise, and lands otherwise acquired, and the beds of any waters belonging to the state. For purposes of this section, iron ore means iron-bearing material where the primary product is iron metal.
All leases for nonferrous metallic minerals or petroleum must be approved by the Executive Council, and any other mineral lease issued pursuant to this section that covers 160 or more acres must be approved by the Executive Council. The rents, royalties, terms, conditions, and covenants of all such leases shall be fixed by the commissioner according to rules adopted by the commissioner, but no lease shall be for a longer term than 50 years, and all rents, royalties, terms, conditions, and covenants shall be fully set forth in each lease issued. The rents and royalties shall be credited to the funds as provided in section 93.22.
The provisions of this section shall not be deemed to repeal or supersede any other applicable provision of law, but shall be supplementary thereto.
