(2) On receipt of a notice under sub-paragraph (1) above the relevant undertaker may cause the mines or minerals to be inspected by a person designated by it for the purpose.

(3) Subject to sub-paragraph (5) and paragraph 3 below, if, where notice has been served under this paragraph, the relevant undertaker—
