93.24 Mining of other than iron ores.  

    Subdivision 1.    Permit, agreement.  Should gold, 
 copper, silver, cobalt, coal, graphite, manganese (four percent 
 or over, dried), iron sulphides or other sulphur ores, 
 titaniferous magnetites, or any other valuable mineral be 
 believed to exist on lands included within a prospecting permit 
 or lease not covering such mineral, upon written application of 
 the permit holder or lessee the terms and conditions on which 
 such mineral may be mined or products recovered therefrom shall 
 be agreed upon by the commissioner and the permit holder or 
 lessee and embodied in a supplement to the permit or lease.  In 
 case they are unable to agree each shall choose a referee.  The 
 two persons thus selected shall choose a third.  The decision of 
 this board shall be final and binding on the parties in 
 interest.  Any iron or iron ore extracted from iron sulphides, 
 sulphur ores or titaniferous magnetites mined under such a 
 supplemental agreement shall be paid for in accordance with the 
 minimum schedule for taconite concentrates provided in section 
 93.20, schedule 7, and any iron or iron ore extracted from any 
 other kind of ore hereinbefore specified mined under such a 
 supplemental agreement shall be paid for at rates fixed by 
 agreement or arbitration as hereinbefore provided.  

    Subd. 2.    Rental, payments.  If, upon the application 
 of the permit holder or lessee the commissioner shall determine 
 that the lands covered by any mining permit or lease are 
 principally valuable for the iron sulphides or other sulphur 
 ores or titaniferous magnetites contained therein, and have no 
 substantial value because of ores of the kind defined in section 
 93.20, schedules 1 to 6, the rental required in any lease issued 
 pursuant to such permit, or any lease modified as above 
 provided, shall be payable at the same rates, and in the same 
 manner provided in section 93.20 in cases of leases for the 
 mining of taconite ore.  Thereupon such lease shall be 
 designated as an iron sulphide or sulphur ore mining lease or a 
 titaniferous magnetite lease, as the case may be.  

    Subd. 3.    Increase of rental.  If, following the 
 issuance or designation of a lease as an iron sulphide or 
 sulphur ore or titaniferous magnetite mining lease, additional 
 information acquired by the commissioner of natural resources 
 shall disclose that the lands covered by the lease have 
 merchantable deposits of iron ore of the classes defined in 
 section 93.20, schedules 1 to 6, which deposits, without 
 reference to the iron sulphide or sulphur ore or titaniferous 
 magnetites in such lands, would give substantial value thereto, 
 the commissioner shall report the facts to the executive 
 council, and thereupon further action shall be taken as provided 
 by section 93.191, subdivision 3, in the case of taconite iron 
 ore mining leases.
