29.2. Despite section 29.1, where an operator so elects in the return it is required to file under section 36 for a fiscal year that begins after 31 December 2013 and that is deemed under section 2.1 to end immediately before the time at which the operator ceases for an indeterminate period all activities that relate to its mining operation, the operator’s mining tax on its annual profit for that fiscal year is equal to the mining tax that would otherwise be determined under section 29.1 if “profit margin” were replaced in subparagraphs 2 to 5 of the second paragraph of section 29.1 by “adjusted profit margin”.
