Ethiopia also has large mineral resources and oil potential in some of the less inhabited regions. Political instability in those regions, however, has inhibited development. Ethiopian geologists were implicated in a major gold swindle in 2008. Four chemists and geologists from the Ethiopian Geological Survey were arrested in connection with a fake gold scandal, following complaints from buyers in South Africa. Gold bars from the National Bank of Ethiopia were found by police to be gilded metal, costing the state around US$17 million, according to the Science and Development Network website.
