Summary

Owners of a uranium lease or a pending uranium lease application have the right to place mining claims on the same land for 120 days after August 13, 1954, but only under the rules of this chapter and any earlier valid U.S. rights. Any mining claim placed this way must yield to any mining claim that was located before February 10, 1954 and was valid on August 13, 1954 (or that later becomes valid under this chapter). If the same land is covered by both a lease and a pending application, the leaseholder has priority. If several applications conflict, the one posted first under the Atomic Energy Commission’s Domestic Uranium Program Circular 7 (10 C.F.R. 60.7(c)) has priority if other posting rules were met; otherwise priority is by the filing time with the Commission. A mining claim made under these rules ends 30 days after its notice or certificate is filed unless, within those 30 days, the lease or application owner files a withdrawal or release with the Atomic Energy Commission and records notice of that filing in the county office. Except for the 120-day right above, no new mining claim is valid on land that was already covered by a uranium lease or lease application at the time the claim was located. A posted notice under Circular 7 counts as putting the tract into an application from the time of posting if the posting met the other requirements; if not, it counts from the time the application was filed with the Commission.

(a)Subject to the conditions and provisions of this chapter and to any valid prior rights acquired under the laws of the United States, the owner of any pending uranium lease application or of any uranium lease shall have, for a period of one hundred and twenty days after August 13, 1954, as limited in subsection (b) of this section, the right to locate mining claims upon the lands covered by said application or lease.
(b)Any rights under any such mining claim so hereafter located pursuant to the provisions of subsection (a) of this section shall be subject to any rights of the owner of any mining claim which was located prior to February 10, 1954, and which was valid on August 13, 1954 or which may acquire validity under the provisions of this chapter. As to any lands covered by a uranium lease and also by a pending uranium lease application, the right of mining location under this section, as between the owner of said lease and the owner of said application, shall be deemed as to such conflict area to be vested in the owner of said lease. As to any lands embraced in more than one such pending uranium lease application, such right of mining location, as between the owners of such conflicting applications, shall be deemed to be vested in the owner of the prior application. Priority of such an application shall be determined by the time of posting on a tract then available for such leasing of a notice of lease application in accordance with paragraph (c) of the Atomic Energy Commission’s Domestic Uranium Program Circular 7 (10 C.F.R. 60.7 (c)) provided there shall have been timely compliance with the other provisions of said paragraph (c) or, if there shall not have been such timely compliance, then by the time of the filing of the uranium lease application with the Atomic Energy Commission. Any rights under any mining claim located under the provisions of this section shall terminate at the expiration of thirty days after the filing for record of the notice or certificate of location of such mining claim unless, within said thirty-day period, the owner of the uranium lease application or uranium lease upon which the location of such mining claim was predicated shall have filed with the Atomic Energy Commission a withdrawal of said application or a release of said lease and shall have recorded a notice of the filing of such withdrawal or release in the county office wherein such notice or certificate of location shall be of record.
(c)Except as otherwise provided in subsections (a) and (b) of this section, no mining claim hereafter located shall be valid as to any lands which at the time of such location were covered by a uranium lease application or a uranium lease. Any tract upon which a notice of lease application has been posted in accordance with said paragraph (c) of said Circular 7 shall be deemed to have been included in a uranium lease application from and after the time of the posting of such notice of lease application: Provided, That there shall have been timely compliance with the other provisions of said paragraph (c) or, if there shall not have been such timely compliance, then from and after the time of the filing of a uranium lease application with the Atomic Energy Commission.
