9(1)The provisions of this and the next following paragraph shall have effect in relation to land to which this Schedule applies where, after the end of the period of occupation, it continues to be subject to a mining lease the benefit of which is held for the purposes of a mineral undertaking, and that mining lease contains a provision as to minimum rent.E+W+S
(2)For each year after the period of occupation there shall be assessed the minimum rent liability (if any) which the mineral operator might reasonably have been expected to incur under that mining lease if—
(a)the compulsory rights order had not been made, and
(b)during the period of occupation, he had exercised the relevant rights and facilities in the manner in which (had that order not been made) he might reasonably have been expected to exercise them.
(3)For each such year there shall also be assessed, in the circumstances existing at the end of the period of occupation, the minimum rent liability (if any) which the mineral operator might reasonably be expected to incur under that mining lease, on the assumption that, during that period, he had exercised the relevant rights and facilities (so far as was reasonably practicable, having regard to the effect of the compulsory rights order) in such manner as in the circumstances he might have reasonably been expected to exercise them.
(4)In this and the next following paragraph any reference to a minimum rent liability for any year, in relation to a mining lease, is a reference to the difference between—
(a)the rent payable for that year under that mining lease, and
(b)the rent which would have been payable for that year under that mining lease if the lease had not contained any provision as to minimum rent.
(5)The preceding provisions of this paragraph shall have effect in relation to an order conferring working rights as they have effect in relation to a mining lease.
(6)In this paragraph “rent” includes yearly or other rent, and any toll, duty, royalty or other annual or periodical payment in the nature of rent, whether payable in money or in money’s worth or otherwise.
