Prior to the issuance of a lease under this subpart, the applicant, at his/her own expense, shall be required to have a correct survey made under authority of a cadastral engineer, such survey to show the exterior surface boundaries of the entire lease tract, not each individual mining claim where more than one claim is involved, which boundaries are to be distinctly marked by monuments on the ground. Application for authorization of survey shall be made in accordance with subpart 1821 of this title.
