The beneficiation hub is ideally located in the heartland of the Highveld coal fields and will add significantly to the country's coal beneficiation infrastructure. The acquisition will sustain employment following the recent depletion of the reserves at Inyanda Colliery, boosting mining transformation and supporting national beneficiation as described in South Africa's Mining Charter.

relatively good news for South Africa as the country's main coal export destination is in fact Europe. South Africa, the largest exporter of coal to Europe, shipped some 74% of the country's total exports in 2002, and 80% in 2003. Last year's exports from the Richards Bay Coal Terminal (RBCT) exceeded their 68 million ton target.
