Stadsraad van Alberton v Briti BK

The respondent, a manufacturer of roof and floor tiles, claimed damages from the appellant (a local authority) for flooding allegedly negligently caused by the appellant's diversion of stormwater onto the respondent's property. The respondent operated an open-pit clay mine (quarry C) on the property which supplied clay to its manufacturing plant. Quarry C was first flooded during the 1995-1996 rainy season and remained flooded until November 1999 when it was pumped out by agreement with the appellant. It flooded again in February 2000 and was only pumped out in May 2001 after a new stormwater drainage system was installed. The respondent had acquired a large stockpile of already-mined clay from Corobrick, stored both in a heap near the plant and stocked in quarry C. The flooding prevented access to the clay in quarry C and allegedly increased moisture levels affecting the kiln floors, causing production losses. The respondent claimed damages for the difference between profits it would have earned but for the flooding and actual reduced profits for 1998-2001. The parties agreed to a preliminary hearing on specific issues: whether the respondent would have mined clay from quarry C but for the flooding, whether such mining would have been unauthorized, and whether unauthorized mining would legally bar recovery of damages.

• Whether the removal of already-mined clay from quarry C and its processing constituted 'mining' as defined in the Minerals Act 50 of 1991
• Whether activities involving already-extracted minerals fall within the definition of 'mine' (as a verb) in the Act
• Whether unauthorized mining, if it had occurred, would preclude the recovery of damages for production losses
• The interpretation of 'excavation' and 'mining' under section 1 of the Minerals Act 50 of 1991

The appeal was dismissed with costs. The court a quo's order (that the 'special plea' be dismissed) was upheld.

The removal of already-mined and stockpiled clay from an excavation to the surface, and the processing of such clay to make it ready for use, does not constitute 'mining' as defined in section 1 of the Minerals Act 50 of 1991. 'Mining' requires the making of an excavation in the earth 'for the purpose of searching for or winning a mineral'. Once a mineral has already been won and extracted, further processing and transportation of that mineral falls outside the statutory definition of 'mining' and does not require authorization under the Act.

The Court noted that the characterization of the defense as a 'special plea' in the technical legal sense was probably incorrect, but stated that this characterization was unimportant and deserved no further mention. The Court also observed that the advantages of having questions of law or fact determined by separate preliminary proceedings under Rule 33(4) are recognized where such questions, if decided in a particular way, would be decisive of the case as a whole or substantial portions of the relief claimed, citing Van Streepen en Germs (Pty) Ltd v Transvaal Provincial Administration 1987 (4) SA 569 (A). The Court found that in this case it was expedient and cost-effective to address the identified issues by way of a separate hearing.

This case is significant in South African mining law for clarifying the scope of the definition of 'mining' under the Minerals Act 50 of 1991. It establishes that post-extraction activities involving already-won minerals, including their removal from excavations, processing, and transportation, do not constitute 'mining' requiring authorization under the Act. The judgment provides important guidance on distinguishing between the extraction of minerals (which requires authorization) and subsequent handling and processing of already-extracted minerals (which does not). This interpretation has implications for the mineral processing industry and the regulation of activities involving stockpiled or previously-mined minerals.
