The performance of not less than $100 worth of labor or the
making of improvements aggregating such amount, which labor or
improvements are required under the provisions of section 28 of
this title to be made during each year, may be deferred by the
Secretary of the Interior as to any mining claim or group of claims
in the United States upon the submission by the claimant of
evidence satisfactory to the Secretary that such mining claim or
group of claims is surrounded by lands over which a right-of-way
for the performance of such assessment work has been denied or is
in litigation or is in the process of acquisition under State law
or that other legal impediments exist which affect the right of the
claimant to enter upon the surface of such claim or group of claims
or to gain access to the boundaries thereof.
