An atrasero (tunnel miner) lights a cigarette before entering a medium-sized shaft located on the steep slopes of Mt. Diwata, southern Philippines. The Diwalwal gold rush area, located on Mindanao island's Mt. Diwata, has attracted migrant workers from all over the Philippines who dig for gold to seek their fortunes. Since the gold rush began in the 1980s, scores of miners have been killed by landslides and shoot-outs inside the hotly-contested tunnels. The most recent tragedy occured in November 2005 when 13 miners died in a sub-terranean explosion.
