A worker waits as his gold is melted before it is weighed at a gold shop at the Wad Bushara gold mine near Abu Delelq in Gadarif State, Wad Bushara April 27, 2013. Sudan exported $2.2 billion worth of gold last year and hopes to produce around 50 tonnes of gold in 2013, which would potentially make it Africa's third-largest gold miner and push it into the top 15 producers globally. The Wad Bushara gold mine has about 2,000 workers who earn an average of $15 a day. Picture taken April 27. REUTERS/Mohamed Nureldin Abdallah (SUDAN - Tags: BUSINESS EMPLOYMENT COMMODITIES)
