43 C.F.R. § 2711.5
Patents and other conveyance documents issued under this part shall contain a reservation to the United States of all minerals. Such minerals shall be subject to the right to explore, prospect for, mine, and remove under applicable law and such regulations as the Secretary may prescribe. However, upon the filing of an application as provided in part 2720 of this title, the Secretary may convey the mineral interest if all requirements of the law are met. Where such application has been filed and meets the requirements for conveyance, the authorized officer may withhold issuance of a patent or other document of conveyance on lands sold under this part until processing of the mineral conveyance application is completed, at which time a single patent or document of conveyance for the entire estate or interest of the United States may be issued.
