Prior to the expiration of the trust period of any Indian allottee to whom a trust or other patent containing restrictions upon alienation has been or shall be issued under any law or treaty the President may, in his discretion, continue such restrictions on alienation for such period as he may deem best: Provided, however, That this shall not apply to lands in the former Indian Territory.

For the purpose of allowing any Indian allottee to sell for townsite purposes any portion of the lands allotted to him, the Secretary of the Interior may, by order, remove restrictions upon the alienation of such lands and issue fee-simple patents therefor under such rules and regulations as he may prescribe.

Whenever, in any law or treaty or in any patent issued to Indian allottees for lands in severalty pursuant to such law or treaty, there appears a provision to the effect that the lands so allotted cannot be alienated without the consent of the President of the United States, the Secretary of the Interior shall have full power and authority to consent to or approve of the alienation of such allotments, in whole or in part, in his discretion, by deed, will, lease, or any other form of conveyance, and such consent or approval by the Secretary of the Interior on and after September 21, 1922, had in all such cases shall have the same force and legal effect as though the consent or approval of the President had previously been obtained: Provided, however, That the approval by the Secretary of the Interior of wills by Indian allottees or their heirs involving lands held under such patents shall not operate to remove the restrictions against alienation unless such order of approval by said Secretary shall specifically so direct.

The restricted allotment of any Indian may be leased for farming and grazing purposes by the allottee or his heirs, subject only to the approval of the superintendent or other officer in charge of the reservation where the land is located, under such rules and regulations as the Secretary of the Interior may prescribe: Provided, That this provision shall not apply to the Five Civilized Tribes.

From and after thirty days from February 11, 1936 the restricted lands belonging to Indians of the Five Civilized Tribes in Oklahoma of one-half or more Indian blood, enrolled or unenrolled, may be leased for periods of not to exceed five years for farming and grazing purposes, under such rules and regulations as the Secretary of the Interior may prescribe and not otherwise. Such leases shall be made by the owner or owners of such lands, if adults, subject to approval by the superintendent or other official in charge of the Five Civilized Tribes Agency, and by such superintendent or other official in charge of said agency in cases of minors and of Indians who are non compos mentis.

Whenever it shall appear to the satisfaction of the Secretary of the Interior that the allotted lands of any Indian are arid but susceptible of irrigation and that the allottee, by reason of old age or other disability, cannot personally occupy or improve his allotment or any portion thereof, such lands, or such portion thereof, may be leased for a period not exceeding ten years, under such terms, rules, and regulations as may be prescribed by the Secretary of the Interior.

Whenever it shall be made to appear to the Secretary of the Interior that, by reason of age, disability, or inability, any allottee of Indian lands cannot personally, and with benefit to himself, occupy or improve his allotment or any part thereof, the same may be leased upon such terms, regulations, and conditions as shall be prescribed by the Secretary for a term not exceeding five years, for farming purposes only.

All lands allotted to Indians in severalty, except allotments made to members of the Five Civilized Tribes and Osage Indians in Oklahoma, may by said allottee be leased for mining purposes for any term of years as may be deemed advisable by the Secretary of the Interior; and the Secretary of the Interior is authorized to perform any and all acts and make such rules and regulations as may be necessary for the purpose of carrying the provisions of this section into full force and effect: Provided, That if the said allottee is deceased and the heirs to or devisees of any interest in the allotment have not been determined, or, if determined, some or all of them cannot be located, the Secretary of the Interior may offer for sale leases for mining purposes to the highest responsible qualified bidder, at public auction, or on sealed bids, after notice and advertisement, upon such terms and conditions as the Secretary of the Interior may prescribe. The Secretary of the Interior shall have the right to reject all bids whenever in his judgment the interests of the Indians will be served by so doing, and to readvertise such lease for sale.

On and after May 11, 1938, unallotted lands within any Indian reservation or lands owned by any tribe, group, or band of Indians under Federal jurisdiction, except those specifically excepted from the provisions of sections 396a to 396g of this title, may, with the approval of the Secretary of the Interior, be leased for mining purposes, by authority of the tribal council or other authorized spokesmen for such Indians, for terms not to exceed ten years and as long thereafter as minerals are produced in paying quantities.

Leases for oil- and/or gas-mining purposes covering such unallotted lands shall be offered for sale to the highest responsible qualified bidder, at public auction or on sealed bids, after notice and advertisement, upon such terms and subject to such conditions as the Secretary of the Interior may prescribe. Such advertisement shall reserve to the Secretary of the Interior the right to reject all bids whenever in his judgment the interest of the Indians will be served by so doing, and if no satisfactory bid is received, or the accepted bidder fails to complete the lease, or the Secretary of the Interior shall determine that it is unwise in the interest of the Indians to accept the highest bid, said Secretary may readvertise such lease for sale, or with the consent of the tribal council or other governing tribal authorities, a lease may be made by private negotiations: Provided, That the foregoing provisions shall in no manner restrict the right of tribes organized and incorporated under sections 16 and 17 of the Act of June 18, 1934 (48 Stat. 984) [25 U.S.C. 5123, 5124], to lease lands for mining purposes as therein provided and in accordance with the provisions of any constitution and charter adopted by any Indian tribe pursuant to the Act of June 18, 1934 [25 U.S.C. 5101 et seq.].

On and after May 11, 1938, lessees of restricted Indian lands, tribal or allotted, for mining purposes, including oil and gas, shall furnish corporate surety bonds, in amounts satisfactory to the Secretary of the Interior, guaranteeing compliance with the terms of their leases: Provided, That personal surety bonds may be accepted where the sureties deposit as collateral with the said Secretary of the Interior any public-debt obligations of the United States guaranteed as to principal and interest by the United States equal to the full amount of such bonds, or other collateral satisfactory to the Secretary of the Interior, or show ownership to unencumbered real estate of a value equal to twice the amount of the bonds.

All operations under any oil, gas, or other mineral lease issued pursuant to the terms of sections 396a to 396g of this title or any other Act affecting restricted Indian lands shall be subject to the rules and regulations promulgated by the Secretary of the Interior. In the discretion of the said Secretary, any lease for oil or gas issued under the provisions of sections 396a to 396g of this title shall be made subject to the terms of any reasonable cooperative unit or other plan approved or prescribed by said Secretary prior or subsequent to the issuance of any such lease which involves the development or production of oil or gas from land covered by such lease.

The Secretary of the Interior may, in his discretion, authorize superintendents or other officials in the Indian Service to approve leases for oil, gas, or other mining purposes covering any restricted Indian lands, tribal or allotted.

Sections 396a, 396b, 396c, and 396d of this title shall not apply to the Crow Reservation in Montana, the ceded lands of the Shoshone Reservation in Wyoming, the Osage Reservation in Oklahoma, nor to the coal and asphalt lands of the Choctaw and Chickasaw Tribes in Oklahoma.

The Secretary of the Interior, to avoid waste or to promote the conservation of natural resources or the welfare of the Indians, is authorized in his discretion to approve leases of lands that are subject to lease under section 396 or 396a of this title, for the subsurface storage of oil and gas, irrespective of the lands from which initially produced, and the Secretary is authorized, in order to provide for the subsurface storage of oil or gas, to approve modifications, amendments, or extensions of the oil and gas or other mining lease(s), if any, in effect as to restricted Indian lands, tribal or allotted, and may promulgate rules and regulations consistent with such leases, modifications, amendments, and extensions, relating to the storage of oil or gas thereunder. Any such leases may provide for the payment of a storage fee or rental on such stored oil or gas or, in lieu of such fee or rental, for a royalty other than that prescribed in the lease when such stored oil or gas is produced in conjunction with oil or gas not previously produced. It may be provided that any oil and gas lease under which storage of oil or gas is so authorized shall be continued in effect at least for the period of such storage use and so long thereafter as oil or gas not previously produced is produced in paying quantities.

Where lands are occupied by Indians who have bought and paid for the same, and which lands are not needed for farming or agricultural purposes, and are not desired for individual allotments, the same may be leased by authority of the council speaking for such Indians, for a period not to exceed five years for grazing, or ten years for mining purposes in such quantities and upon such terms and conditions as the agent in charge of such reservation may recommend, subject to the approval of the Secretary of the Interior.

Unallotted land on Indian reservations other than lands of the Five Civilized Tribes and the Osage Reservation subject to lease for mining purposes for a period of ten years under section 397 of this title may be leased at public auction by the Secretary of the Interior, with the consent of the council speaking for such Indians, for oil and gas mining purposes for a period of not to exceed ten years, and as much longer as oil or gas shall be found in paying quantities, and the terms of any existing oil and gas mining lease may in like manner be amended by extending the term thereof for as long as oil or gas shall be found in paying quantities: Provided, That the production of oil and gas and other minerals on such lands may be taxed by the State in which said lands are located in all respects the same as production on unrestricted lands, and the Secretary of the Interior is authorized and directed to cause to be paid the tax so assessed against the royalty interests on said lands: Provided, however, That such tax shall not become a lien or charge of any kind or character against the land or the property of the Indian owner.

Unallotted lands within the limits of any reservation or withdrawal created by Executive order for Indian purposes or for the use or occupancy of any Indians or tribe may be leased for oil and gas mining purposes in accordance with the provisions contained in section 398 of this title.

The proceeds from rentals, royalties, or bonuses of oil and gas leases upon lands within Executive order Indian reservations or withdrawals shall be deposited in the Treasury of the United States to the credit of the tribe of Indians for whose benefit the reservation or withdrawal was created or who are using and occupying the land, and shall draw interest at the rate of 4 per centum per annum and be available for appropriation by Congress for expenses in connection with the supervision of the development and operation of the oil and gas industry and for the use and benefit of such Indians: Provided, That said Indians, or their tribal council, shall be consulted in regard to the expenditure of such money, but no per capita payment shall be made except by Act of Congress.

Changes in the boundaries of reservations created by Executive order, proclamation, or otherwise for the use and occupation of Indians shall not be made except by Act of Congress.

The Secretary of the Interior is hereby authorized, under such rules and regulations as he may prescribe, to allow any person who prior to May 27, 1924, filed an application for a permit in accordance with the provisions of the Act of February 25, 1920, to prospect for oil and gas upon lands within an Indian reservation or withdrawal created by Executive order who shall show to the satisfaction of the Secretary of the Interior that he, or the party with whom he has contracted, has done prior to January 1, 1926, any or all of the following things, to wit, expended money or labor in geologically surveying the lands covered by such application, has built a road for the benefit of such lands, or has drilled or contributed toward the drilling of the geologic structure upon which such lands are located, or who in good faith has either filed a motion for reinstatement or rehearing; or performed any other act which in the judgment of the Secretary of the Interior entitles him to equitable relief, to prospect for a period of two years from March 3, 1927, or for such further time as the Secretary of the Interior may deem reasonable or necessary for the full exploration of the land described in his application under the terms and conditions therein set out, and a substantial contribution toward the drilling of the geologic structure thereon by such applicant for a permit thereon may be considered as prospecting under the provisions hereof; and upon establishing to the satisfaction of the Secretary of the Interior that valuable deposits of oil and gas have been discovered within the limits of the land embraced in any such application, he shall be entitled to a lease for one-fourth of the land embraced in the application: Provided, That the applicant shall be granted a lease for as much as one hundred and sixty acres of said lands if there be that number of acres within the application. The area to be selected by the applicant shall be in compact form and, if surveyed, to be described by the legal subdivisions of the public land surveyed; if unsurveyed, to be surveyed by the Government at the expense of the applicant for lease in accordance with rules and regulations to be prescribed by the Secretary of the Interior, and the lands leased shall be conformed to and taken in accordance with the legal subdivisions of such surveys; deposit made to cover expense of surveys shall be deemed appropriated for that purpose, and any excess deposits may be repaid to the person or persons making such deposit or their legal representatives. Such leases shall be for a term of twenty years upon a royalty of 5 per centum in amount or value of the production and the annual payment in advance of a rental of $1 per acre, the rental paid for any one year to be credited against the royalties as they may accrue for that year, with the preferential right in the lessee to renew the same for successive periods of ten years upon such reasonable terms and conditions as may be prescribed by the Secretary of the Interior. The applicant shall also be entitled to a preference right to a lease for the remainder of the land in his application at a royalty of not less than 12½ per centum in amount or value of the production, the royalty to be determined by competitive bidding or fixed by such other methods as the Secretary of the Interior may by regulations prescribe: Provided further, That the Secretary of the Interior shall have the right to reject any or all bids.

No money accruing from any lease or sale of lands held in trust by the United States for any Indian shall become liable for the payment of any debt of, or claim against, such Indian contracted or arising during such trust period, or, in case of a minor, during his minority, except with the approval and consent of the Secretary of the Interior.

The shares of money due minor Indians as their proportion of the proceeds from the sale of ceded or tribal Indian lands, whenever such shares have been withheld from their parents, legal guardians, or others, and retained in the United States Treasury by direction of the Secretary of the Interior, shall draw interest at the rate of 3 per centum per annum, unless otherwise provided for, from the period when such proceeds have been or shall be distributed per capita among the members of the tribe of which such minor is a member; and the Secretary of the Treasury is authorized and directed to allow interest on such unpaid amounts belonging to said minors as shall be certified by the Secretary of the Interior as entitled to draw interest under this section.

In any case where the restrictions as to alienation have been removed with respect to any Indian allottee, or as to any portion of the lands of any Indian allottee, and such allottee as an individual, or as a member of any tribe, has an interest in any fund held by the United States beyond the amount by law chargeable to such Indian or tribe on account of advances, the Commissioner of Indian Affairs is authorized, prior to the date at which any penalties for the nonpayment of taxes would accrue under the laws of the State or Territory in which such land is situated, to pay such taxes and charge the amount thereof to such allottee, to be deducted from the share of such allottee in the final distribution or payment to him from such fund: Provided, That no such payment shall be made by said Commissioner where it is in excess of the amount which will ultimately be due said allottee.
