Local miner Cesar Abac uses a wooden bowl and mercury to pan for gold near at the village of Las Cristinas, southern Bolivar State, Venezuela on January 30, 2009. Four centuries after the lure of Venezuelan gold brought ruin to English explorer Sir Walter Raleigh, the riches at one giant mine some say is cursed still haunt treasure hunters from across the globe.
