Projects completed in: Coal (surface and underground) Mineral sands Platinum (surface and underground) Alluvial Gold /Diamonds Manganese Iron (surface and underground) Gold (surface and underground) Other: Training in the use of Micromine Modelling in Micromine Pit Optimisation and scheduling in Micromine Mine layout design and Reserve determination Scheduling in XPAC Micromine Africa Mining Engineer Timeframe May 2002 to May 2005 Mr van Vuuren accepted a position as Mining Engineer with Micromine. This position was created because of the expansion of Micromine Africa. His main responsibilities include the following: Do mining resource evaluation Do mine design Do mine scheduling Do mine capital and operational costing Do mining risk assessment Assist with pre-feasibility and feasibility studies Assisted with the mining project assessment for major mining houses such as, BHP-Billiton and Randgold Resources Assist with marketing of in-house software Sasol Mining Planning Manager Timeframe July 1995 to April 2002 The Export Project, that resulted in the Export Business of Sasol Mining, started as a result of reserves that were not fit for the gasification Page 3

4 process, but had high CVs, and thus suitable for the utilities market. At the time, the Export Project implementation was complete, the coal market was severely depressed. It was decided to model the Export Business to enable management to determine what the drivers of the Export Business were and aid management in making decisions about the future of the Export Business. It was Mr van Vuuren s responsibility to model the Export Business and run various scenarios to determine which would be the best to follow. The business model was also used to schedule the reserve and deploy the colliery in such a way that the NPV would be maximised. As planning manager for the export business, he reported to the Mine Manager and the Plant Manager and was a member of the Export Business Management team. His accomplishments were: Used and coordinated consultants to model the export business Implemented a market driven planning system that included the mine, washing plant and export facility to optimise the export reserve and maximise NPV Successful implementation of the Sasol business planning cycle Successful implementation of zero-based budgeting Successful implementation of an ISO14001 program Successful implementation of a mine water management system to minimise the effect on the environment Sasol Mining Underground Manager Mining Services Timeframe July 1995 to April 2002 Twistdraai Colliery supplied coal to the Synthetic Fuels plant at Secunda. Mr van Vuuren s main responsibility was to manage the mining services department.
