Peru's biggest federation of mining unions said workers will go on strike nationwide starting on Monday despite efforts by the government to avert the walkout, officials said on Sunday.
It would be the second nationwide strike this year in Peru, the world's third-largest producer of copper and zinc, and fifth-largest producer of gold. A strike in May, which was halted after five days, pushed up global metals prices.
"Mine workers will go on strike tomorrow (Monday)," said Julio Ortiz, a director of the federation.
