  2. Overview of Presentation • What is the Chamber of Mines • Mining: Historical Context • Mining and Water Quality • Mining and Water Security: Some Perspectives

  3. Chamber of Mines • A premier mining sector employers’ organisation • The principal advocate of mining policy positions endorsed by mining employers • Exists today primarily to provide strategic support and advisory input to its members • Members account for 90% of SA’s mineral production by value

  4. Mining: Historical Context • Mining played a critical role in SA’s economic development, e.g. JHB from mining camp to a major African city • Social legacies: • Labour relations, social and occupational health issues • Environmental footprint: land, soil sterilisation, biodiversity degradation and water impacts • Regulatory/Corporate inadequacies
