Johannesburg - South Africa's Association of Mineworkers and Construction Union (AMCU) said on Monday its workers had voted in favour of a strike over wages at world No. 2 platinum producer Impala Platinum.

“They said to go on strike,” AMCU spokesman Jimmy Gama told Reuters.

He gave no further details nor did he specify a date for the stoppage to start.

AMCU has a green light from a state mediator to launch strikes at Implats, the world's top platinum producer Anglo American Platinum, and the third largest producer, Lonmin. - Reuters
