Argentina tells Barrick to overhaul Veladero gold mine

By Caroline Stauffer and Susan Taylor BUENOS AIRES/TORONTO (Reuters) - Argentina mining officials told Barrick Gold Corp it must overhaul environmental and operating processes at its Veladero mine, following last week's cyanide solution spill, while the country's environment ministry asked for a total suspension of operations, according to statements on Friday. National and provincial officials told Barrick executives at a Thursday meeting that the Canadian company's ongoing business in the country hinges on a new working plan for the open pit mine, the country's energy minister said. A pipe carrying cyanide solution ruptured at the open pit mine on March 28, the third incident at the mine in 18 months involving cyanide-bearing solution.
