Miner Rahmat Halim (R), 35, and his team smoke during a break at the site of Poboya gold mining area at Indonesia's Central Sulawesi province in this April 19, 2012 file photo. With the world's fifth-largest gold reserves, estimated at 3,000 tonnes, Indonesia is eager to ramp up exploration and production as it pursues its ambitious target of becoming a top 10 global economy by 2025. But illegal mining, politicking between central and regional government and a spate of demonstrations and violent attacks against junior gold miners are hampering development of the sector and could deprive it of crucial foreign investment.
