The mining industry of Sudan was mostly driven by extraction fuel minerals, with petroleum accounting for a substantial contribution to the country's economy, until the autonomous region of Southern Sudan became an independent country in July 2011. Gold, iron ore, and base metals are mined in the Hassai Gold Mine. Chromite is another important mineral extracted from the Ingessana Hills.
