Code of Federal Regulations Title 25. Indians § 25.227.4 Sale of oil and gas leases

(a) At such times and in such manner as he may deem appropriate, after being authorized by the Joint Business Council of the Shoshone and Arapahoe Tribes or its authorized representative, the superintendent shall publish notices at least thirty days prior to the sale, unless a shorter period is authorized by the Secretary of the Interior or his authorized representative, that oil and gas leases on specific tracts, each of which shall be in a reasonably compact body, will be offered to the highest responsible bidder for a bonus consideration, in addition to stipulated rentals and royalties. Each bid must be accompanied by a cashier's check, certified check, or postal money order, payable to the payee designated in the invitation to bid, in an amount not less than 25 percent of the bonus bid. Within 30 days after notification of being the successful bidder, said bidder must remit the balance of the bonus, the first year's rental, and his share of the advertising costs, and shall file with the superintendent the lease in completed form. The superintendent may for good and sufficient reasons, extend the time for completion and submission of the lease form, but no extension shall be granted for remitting the balance of monies due. If the successful bidder fails to pay the full consideration within said period, or fails to file the completed lease within said period or extension thereof, or if the lease is disapproved through no fault of the lessor or the Department of the Interior, 25 percent of the bonus bid will be forfeited for the use and benefit of the Shoshone and Arapahoe Tribes.

(b) All notices or advertisements of sales of oil and gas leases shall reserve to the Secretary of the Interior the right to reject all bids when in his judgment the interests of the Indians will be best served by so doing, and that if no satisfactory bid is received, or if the accepted bidder fails to complete the lease, or if the Secretary of the Interior shall determine that it is unwise in the interests of the Indians to accept the highest bid, the Secretary may readvertise such lease for sale, or if deemed advisable, with the consent of the tribal council or other governing tribal authorities, a lease may be made by private negotiations. The successful bidder or bidders will be required to pay his or their share of the advertising costs. Amounts received from unsuccessful bidders will be returned;  but when no bid is accepted on a tract, the costs of advertising will be assessed against the applicant who requested that said tract be advertised.
