Summary

The Secretaries of the Interior and Commerce may make formal agreements to work with people, companies, states, cities, schools, or other groups. Before drilling on land where the minerals are not owned by the United States, they must sign contracts with the mineral owners, lessees, or both. Those contracts must say that if potash minerals or oil are found and sold, the owners or lessees must pay the government and its partners a royalty of at least 2½% of the sale value. Payments continue until the total royalties equal no more than the exploration costs, as the two Secretaries decide. Federal claims for reimbursement under the contracts automatically end twenty years after the contracts are approved unless the parties agree to end them sooner. The contracts cannot stop the Secretaries from choosing drilling locations or running exploration, so long as those actions do not unreasonably damage the land or its improvements, and they must state the United States is not liable for damages from reasonable use of the surface needed to do the work.

The Secretary of the Interior and the Secretary of Commerce jointly are hereby authorized, within their discretion, to cooperate under formal agreement with individuals, associations, corporations, States, and municipalities, educational institutions, or other bodies, for the purposes of this section: Provided, That before undertaking drilling operations upon any tract or tracts of land, the mineral deposits of which are not the property of the United States, the Secretary of the Interior and the Secretary of Commerce jointly shall enter into a contract or contracts with the owners or lessees, or both, of the mineral rights therein, and the aforesaid contract or contracts shall provide, among other things, that, if deposits of potash minerals or oil shall be discovered in pursuance of operations under said contract or contracts and if and when said mineral deposits shall be mined and sold, the owners or lessees, or both, of said mineral rights shall pay to the Government and its cooperators a royalty of not less than 2½ per centum of the sale value of any potash minerals and oil therefrom, said payments to continue until such time as the total amount derived from said royalty is equal to not more than the cost of the exploration, as may be determined by the Secretary of the Interior and the Secretary of Commerce jointly: Provided further, That all Federal claims for reimbursement under this section shall automatically expire twenty years from the date of approval of the contracts entered into, in accordance with the provisions thereof, unless sooner terminated by agreement between the owners or lessees of the potash mineral rights and oil and the Secretary of the Interior and the Secretary of Commerce jointly: Provided further, That said contract or contracts shall not restrict the Secretary of the Interior and the Secretary of Commerce jointly in the choice of drilling locations within the property or in the conduct of the exploratory operations, so long as such selection or conduct do not interfere unreasonably with the surface of the land or with the improvements thereof, and said contract or contracts shall provide that the United States shall not be liable for damages on account of such reasonable use of the surface as may be necessary in the proper conduct of the work.
