Subject to the provisions of this chapter and to any valid
intervening rights acquired under laws of the United States, any
mining claim located under the mining laws of the United States
subsequent to July 31, 1939, and prior to January 1, 1953, on lands
of the United States which were, at the time of such location -

leasing laws; or
(2) covered by an application or offer for a permit or lease
which had been filed under the mineral leasing laws; or
(3) known to be valuable for minerals subject to disposition
under the mineral leasing laws;
shall be effective to the same extent as if such mining claim had
been located on lands which were at the time of such location
subject to location under the mining laws of the United States:
Provided, however, That in order to obtain the benefits of this
chapter, the owner of any such mining claim shall, not later than
one hundred and twenty days after August 12, 1953, post on such
claim in the manner required for posting notice of location of
mining claims and file for record in the office where the notice or
certificate of location of such claim is of record an amended
notice of location of such claim, stating that such notice is filed
pursuant to the provisions of this chapter and for the purpose of
obtaining the benefits thereof.
(b) Labor and improvement
Labor performed or improvements made upon or for the benefit of
such mining claims after the original location thereof shall be
recognized as applicable thereto for all purposes to the same
extent as labor performed and improvements made upon or for the
benefit of mining claims which are not affected by this chapter.
(c) Withdrawal or reservation
Any withdrawal or reservation made after the original location of
such mining claim affecting land covered by such mining claim is
modified and amended so that the effect thereof upon such mining
claim shall be the same as if such mining claim had been located
upon lands of the United States, which, subsequent to July 31,
1939, and prior to the date of such withdrawal, were subject to
location under the mining laws of the United States.
