An Andean woman and a girl are seen next to the Cortada lagoon during a march against Newmont Mining's Conga gold project at Peru's region of Cajamarca, November 24, 2011. Peru's prime minister on December 2, 2011, said Newmont Mining must set aside money to finance social projects and any environmental damage as a precondition for moving forward on a stalled $4.8 billion gold mine project. Opponents of Newmont Mining's $4.8 billion Conga project refused to end their rallies on November 30, 2011, saying Peru must permanently cancel the proposed mine after temporarily halting work on it to avert violence. Protesters and farmers say the mine would cause pollution and hurt water supplies by replacing a string of alpine lakes with artificial reservoirs. REUTERS/Enrique Castro-Mendivil
