The Vancouver Sun reports in its Saturday edition environmental groups in Argentina on Friday criticized a judge's decision to lift orders suspending operations of Barrick Gold's Veladero mine, which recently had a cyanide spill. The unbylined item says groups including the Argentine Association of Environmental Lawyers argued it was too soon for investigators to know the severity of the spill or whether the problem had been corrected. "We need to see the results" of the environmental tests, said local Greenpeace activist Gonzalo Strano. On Tuesday, Judge Pablo Oritja suspended all operations using cyanide at the mine, 1,265 kilometres northwest of Buenos Aires. Judge Oritja said an environmental impact could not be ruled out, but that waters were not contaminated. On Thursday, the suspension was lifted and on Friday the company the mine was fully operational. On Sept. 13, Barrick said a pipe carrying cyanide at the mine had a valve failure, causing a leak into nearby waters. An investigation determined about 35,300 cubic feet (1,000 cubic metres) of liquid cyanide solution had spilled. In a statement, Barrick denied the cyanide would pose a risk to humans. Barrick closed Friday at $8.64, down 72 cents.
