Chile blocks Glencore Xstrata dam

A Chilean appeals court has preventively blocked a recently approved $733m hydroelectric dam to weigh an environmental appeal, a surprise setback for owners Origin Energy and Glencore Xstrata. Opponents of the 640-megawatt Rio Cuervo project planned in the remote southern Aysen region say it would harm the environment and would be built above a geological fault line in highly-seismic Chile.
