Ezulwini Mining Company (Pty) Ltd v Minister of Mineral Resources and Energy and Others

Ezulwini Mining Company (Pty) Ltd operated a deep-level mine on the West Rand, Gauteng, which required continuous pumping and treatment of extraneous groundwater entering underground workings. Ezulwini ceased underground mining operations in September 2016 due to economic non-viability but continued certain surface processing activities. It nonetheless continued pumping and treating extraneous underground water, as had been done historically. Ezulwini applied for environmental authorisation under NEMA and for an amendment to its water use licence to permit cessation of pumping, but these processes were not finalised. Acting on legal advice that no authorisation was required, Ezulwini sought declaratory relief in the High Court that it was entitled to cease pumping. Gold Fields, operator of an adjacent interconnected mine, opposed and counter-applied, contending that cessation could cause flooding and safety risks. The High Court declared that Ezulwini remained responsible for pumping until a closure certificate was issued under s 43 of the MPRDA. Ezulwini appealed to the Supreme Court of Appeal.

The appeal was largely dismissed. Paragraph 1 of the High Court’s order was set aside and replaced with an order declaring that Ezulwini Mining Company (Pty) Ltd remains responsible for the pumping and treatment of extraneous water from the underground workings of the Ezulwini Mine until the Minister of Mineral Resources and Energy issues a closure certificate in terms of s 43 of the MPRDA. The appeal was otherwise dismissed with costs, including the costs of two counsel.

This judgment authoritatively clarifies that mine operators in South Africa bear continuing environmental management obligations, including pumping and treatment of extraneous water, even after cessation of mining operations, until formal mine closure is certified. It reinforces the life-cycle approach to environmental responsibility under NEMA and the MPRDA, strengthens regulatory control over mine closure, and affirms that environmental obligations cannot be unilaterally terminated by a mining company. The case is significant for mining regulation, environmental protection, and sustainable development jurisprudence.
