§527 Determination of Unpatented Mining Claims
Title 30 › CHAPTER 12 — MULTIPLE MINERAL DEVELOPMENT OF THE SAME TRACTS › § 527
Summary
A person who applies for a federal mineral lease, permit, offer, or similar can ask the Interior Department to publish a public notice about it. To do that, the person must first record a notice in the county where the land is located at least 90 days before asking for publication. The publication request must include a certified copy of that county record, sworn statements by people over 21 who checked the land and say whether anyone was in possession or working it (and give names and addresses if found, or explain efforts to find them), and a certificate from a title company, title abstractor, or attorney listing anyone shown in the county records to have an interest from an unpatented mining claim. The requester pays the cost and must get the publisher to agree to hold the requester responsible for charges. The Interior will publish a notice in a local newspaper describing the land and warning that anyone claiming rights under an unpatented mining claim must file a verified statement at the office named in the notice within 150 days of the first publication. That statement must give the date of location, book and page of record, the survey sections (or unsurveyed tie), whether the person was a locator or purchaser, and the claimant’s name and address and any known others. If no verified statement is filed within 150 days, the claimant is treated as having given up any right to minerals covered by the Leasing Act from that mining claim, consents that the claim (and any patent) is subject to the reservation in section 524, and cannot later assert rights to those Leasing Act minerals. The notice must run for nine weeks or nine issues depending on the paper’s schedule. Within 15 days after the first publication, the requester must personally deliver or mail by registered or certified mail copies of the notice to people found on the land, to anyone who filed a request for copies, and to those named in the title certificate, and then file a sworn affidavit saying they did so. If someone files the required verified statement, the Interior will set a hearing in the county to decide the claim under the department’s usual contest rules. If the hearing upholds the claimant’s rights, later actions under this procedure cannot affect those rights. If the requester failed to deliver or mail required copies to a person, the publication is ineffective as to that person and their rights are not harmed by any failure to file.

(a) Filing of notice Any applicant, offeror, permittee, or lessee under the mineral leasing laws may file in the office of the Secretary of the Interior, or in such office as the Secretary may designate, a request for publication of notice of such application, offer, permit, or lease, provided expressly, that not less than ninety days prior to the filing of such request for publication there shall have been filed for record in the county office of record for the county in which the lands covered thereby are situate a notice of the filing of such application or offer or of the issuance of such permit or lease which notice shall set forth the date of such filing or issuance, the name and address of the applicant, offeror, permittee or lessee and the description of the lands covered by such application, offer, permit or lease, showing the section or sections of the public land surveys which embrace the lands covered by such application, offer, permit, or lease, or if such lands are unsurveyed, either the section or sections which would probably embrace such lands when the public lands surveys are extended to such lands or a tie by courses and distances to an approved United States mineral monument. The filing of such request for publication shall be accompanied by a certified copy of such recorded notice and an affidavit or affidavits of a person or persons over twenty-one years of age setting forth that the affiant or affiants have examined the lands involved in a reasonable effort to ascertain whether any person or persons were in actual possession of or engaged in the working of such lands or any part thereof, and, if no person or persons were found to be in actual possession of or engaged in the working of said lands or any part thereof on the date of such examination, setting forth such fact, or, if any person or persons were so found to be in actual possession or engaged in such working on the date of such examination, setting forth the name and address of each such person, unless affiant shall have been unable through reasonable inquiry to obtain information as to the name and address of any such person, in which event the affidavit shall set forth fully the nature and results of such inquiry. The filing of such request for publication shall also be accompanied by the certificate of a title or abstract company, or of a title abstractor, or of an attorney, based upon such company’s, abstractor’s, or attorney’s examination of the instruments affecting the lands involved, of record in the public records of the county in which said lands are situate as shown by the indices of the public records in the county office of record for said county, setting forth the name of any person disclosed by said instruments to have an interest in said lands under any unpatented mining claim heretofore located, together with the address of such person if disclosed by such instruments of record. Thereupon the Secretary of the Interior, or his designated representative, at the expense of the requesting person (who, prior to the commencement of publication, must furnish the agreement of the publisher to hold such requesting person alone responsible for charges of publication), shall cause notice of such application, offer, permit, or lease to be published in a newspaper having general circulation in the county in which the lands involved are situate. Such notice shall describe the lands covered by such application, offer, permit, or lease, as provided heretofore in the notice to be filed in the office of record of the county in which the lands covered are situate, and shall notify whomever it may concern that if any person claiming or asserting under, or by virtue of, any unpatented mining claim heretofore located, any right or interest in Leasing Act minerals as to such lands or any part thereof, shall fail to file in the office where such request for publication was filed (which office shall be specified in such notice) and within one hundred fifty days from the date of the first publication of such notice (which date shall be specified in such notice), a verified statement which shall set forth, as to such unpatented mining claim: (1) The date of location; (2) The book and page of recordation of the notice or certificate of location; (3) The section or sections of the public land surveys which embrace such mining claim; or if such lands are unsurveyed, either the section or sections which would probably embrace such mining claim when the public land surveys are extended to such lands or a tie by courses and distances to an approved United States mineral monument; (4) Whether such claimant is a locator or purchaser under such location; and (5) The name and address of such claimant and names and addresses so far as known to the claimant of any other person or persons claiming any interest or interests in or under such unpatented mining claim; such failure shall be conclusively deemed (i) to constitute a waiver and relinquishment by such mining claimant of any and all right, title, and interest under such mining claim as to, but only as to, Leasing Act minerals, and (ii) to constitute a consent by such mining claimant that such mining claim and any patent issued therefor, shall be subject to the reservation specified in section 524 of this title, and (iii) to preclude thereafter any assertion by such mining claimant of any right or title to or interest in any Leasing Act mineral by reason of such mining claim. If such notice is published in a daily paper, it shall be published in the Wednesday issue for nine consecutive weeks, or, if in a weekly paper, in nine consecutive issues, or, if in a semiweekly or triweekly paper, in the issue of the same day of each week for nine consecutive weeks. Within fifteen days after the date of first publication of such notice, the person requesting such publication (1) shall cause a copy of such notice to be personally delivered to or to be mailed by registered mail or by certified mail addressed to each person in possession or engaged in the working of the land whose name and address is shown by an affidavit filed as aforesaid, and to each person who may have filed, as to any lands described in said notice, a request for notices, as provided in subsection (d) of this section, and shall cause a copy of such notice to be mailed by registered mail or by certified mail to each person whose name and address is set forth in the title or abstract company’s or title abstractor’s or attorney’s certificate filed as aforesaid, as having an interest in the lands described in said notice under any unpatented mining claim heretofore located, such notice to be directed to such person’s address as set forth in such certificate; and (2) shall file in the office where said request for publication was filed an affidavit showing that copies have been so delivered or mailed. (b) Failure to file verified statement If any claimant under any unpatented mining claim heretofore located which embraces any of the lands described in any notice published in accordance with the provisions of subsection (a) of this section shall fail to file a verified statement, as above provided, within one hundred and fifty days from the date of the first publication of such notice, such failure shall be conclusively deemed, except as otherwise provided in subsection (e) of this section, (i) to constitute a waiver and relinquishment by such mining claimant of any and all right, title, and interest under such mining claim as to, but only as to, Leasing Act minerals, and (ii) to constitute a consent by such mining claimant that such mining claim and any patent issued therefor, shall be subject to the reservation specified in section 524 of this title, and (iii) to preclude thereafter any assertion by such mining claimant of any right or title to or interest in any Leasing Act mineral by reason of such mining claim. (c) Hearings If any verified statement shall be filed by a mining claimant as provided in subsection (a) of this section, then the Secretary of the Interior or his designated representative shall fix a time and place for a hearing to determine the validity and effectiveness of the mining claimant’s asserted right or interest in Leasing Act minerals, which place of hearing shall be in the county where the lands in question or parts thereof are located, unless the mining claimant agrees otherwise. The procedures with respect to notice of such a hearing and the conduct thereof, and in respect to appeals shall follow the then established general procedures and rules of practice of the Department of the Interior in respect to contests or protests affecting public lands of the United States. If, pursuant to such a hearing the final decision rendered in the matter shall affirm the validity and effectiveness of any mining claimant’s right or interest under the mining claim as to Leasing Act minerals, then no subsequent proceedings under this section shall have any force or effect upon the so-affirmed right or interest of such mining claimant under such mining claim. If at any time prior to a hearing the person requesting publication of notice and any person filing a verified statement pursuant to such notice shall so stipulate, then to the extent so stipulated, but only to such extent, no hearing shall be held with respect to rights asserted under that verified statement, and to the extent defined by the stipulation the rights asserted under that verified statement shall be deemed to be unaffected by that particular published notice. (d) Request for copy of notice Any person claiming any right in Leasing Act minerals under or by virtue of any unpatented mining claim heretofore located and desiring to receive a copy of any notice of any application, offer, permit, or lease which may be published as above provided in subsection (a) of this section, and which may affect lands embraced in such mining claim, may cause to be filed for record in the county office of record where the notice or certificate of location of such mining claim shall have been recorded, a duly acknowledged request for a copy of any such notice. Such request for copies shall set forth the name and address of the person requesting copies and shall also set forth, as to each mining claim under which such person asserts rights in Leasing Act minerals: (1) the date of location; (2) the book and page of the recordation of the notice or certificate of location; and (3) the section or sections of the public land surveys which embrace such mining claim; or if such lands are unsurveyed, either the section or sections which would probably embrace such mining claim when the public land surveys are extended to such lands or a tie by courses and distances to an approved United States mineral monument. Other than in respect to the requirements of subsection (a) of this section as to personal delivery or mailing of copies of notices and in respect to the provisions of subsection (e) of this section, no such request for copies of published notices and no statement or allegation in such request and no recordation thereof shall affect title to any mining claim or to any land or be deemed to constitute constructive notice to any person that the person requesting copies has, or claims, any right, title, or interest in or under any mining claim referred to in such request. (e) Failure to deliver or mail copy of notice If any applicant, offeror, permittee, or lessee shall fail to comply with the requirements of subsection (a) of this section as to the personal delivery or mailing of a copy of notice to any person, the publication of such notice shall be deemed wholly ineffectual as to that person or as to the rights asserted by that person and the failure of that person to file a verified statement, as provided in such notice, shall in no manner affect, diminish, prejudice or bar any rights of that person.
