Overview A leading asset amongst our peers Bulyanhulu Our Location  World class – high grade narrow vein deposit  Geological endowment of over 20 million ounces* West Kenya JV Kenya  Located in a mining friendly and stable country  However, history of under-delivery and lack of free cash generation North Mara Tintinba Project Tanzania Mali  Undertaking fundamental re-engineering Hounde Belt JVs Bulyanhulu Burkina Faso of the mine to ensure delivers to its Tanzania geologic potential Buzwagi Tanzania Producing mines Exploration properties * Including produced ounces Investor Site Tour 4 04.02.2016

  5. Setting the scene In 2013 we started the process of fundamentally re-designing Bulyanhulu Past Present  LOM focused on labour intensive  Converted to mechanised mining mining methods methods  50% increase in development metres  Lack of investment in development due to bringing in contractor  Poor maintenance practices, limited  Over 80% of maintenance is planned planned maintenance  Sustaining capital spend has more  Over capitalised (too much equipment than halved, whilst production has on site) increased  Setting achievable targets, in tandem  Optimistic planning led to culture of with a dedicated cultural change failure programme  50% reduction in total workforce,  Too many people, both local and expat with expats down by 55% We’ve made great progress, but still more to do to achieve our goals Investor Site Tour 5 04.02.2016

Upper East Deferred ramp up whilst undertake further definition drilling  Area located 2km east of shaft with existing small scale decline to the area  Includes material on both Reef 1 and the Reef 2 series  Commenced production from development ore in H2 2015  Expected stoping ramp-up in 2016  When developing saw divergence between reserve model and results from the production drilling in Reef 2 series  Previous drill spacing of 100m centres, not tight enough to accurately predict variation in the lode geometries  Spacing is the same as has been used across the mine successfully for last 15 years  Deferred development in the Reef 2 Series whilst undertake definition drilling programme Investor Site Tour 14 04.02.2016
