Sishen Iron Ore Company (Pty) Ltd conducted open-cast iron ore mining in the Northern Cape under a mining right issued in terms of the Mineral and Petroleum Resources Development Act 28 of 2002. As its mining operations expanded westwards, Sishen was required, in terms of its approved Mining Work Programme and applicable safety and environmental legislation, to relocate the neighbouring Dingleton residential township (situated outside the mining area) to maintain a mandatory 500‑metre safety buffer, and to relocate various items of third‑party infrastructure within the mining area (the SWEP infrastructure) to enable optimal extraction of ore. Sishen incurred expenditure in relocating Dingleton, relocating the SWEP infrastructure, paying legal costs associated with advising Dingleton residents on relocation, and relocating a 66kV electricity line supplying mine equipment. For the 2012–2014 tax years, Sishen claimed deductions for this expenditure. The Commissioner for the South African Revenue Service disallowed the deductions, imposed understatement penalties, and levied interest on the resulting tax liability. The Tax Court partially upheld and partially rejected the deductions, leading to an appeal and cross‑appeal before the Supreme Court of Appeal.
The appeal and cross‑appeal were partially upheld. The relocation expenditure relating to Dingleton and the SWEP infrastructure, as well as the 66kV line expenditure, was held to be deductible. Understatement penalties were set aside. The interest levied under s 89quat(2) was set aside and referred back to CSARS for reconsideration. The legal expenditure was held not to be deductible. Costs orders were made in favour of Sishen in respect of both the appeal and cross‑appeal.
The judgment provides authoritative guidance on the deductibility of mining‑related relocation and infrastructure costs under the special capital allowance regime in the Income Tax Act. It clarifies the interpretation of expenditure incurred 'in terms of a mining right' and confirms that compliance‑driven relocation costs integral to lawful and optimal mining operations may qualify for deduction. The case is significant for mining taxpayers facing substantial regulatory and environmental compliance costs.
