In the heart of the Great Dyke of Zimbabwe, within the world’s second-largest known platinum group metals (PGMs) deposits, exploration has started on the 23 903 ha mining area of the Karo platinum project. One year after Cyprus-based Karo Mining signed the $4.2-billion deal to develop the latest integrated platinum mining and refining complex in Zimbabwe, 72 diamond core boreholes totaling 12 000 m has been completed by the first drilling contractor to be mobilised at the site.
