The ongoing underground strike by members of the National Union of Metalworkers of South Africa (Numsa) at Lanxess Chrome Mine (LCM) in Rustenburg was illegal, the mine said on Monday. "The strike has been declared illegal by a Johannesburg court but is ongoing. The main focus of LCM is currently on resolving the situation quickly and safely without any violence and bringing all employees back to surface, well and safe. Meanwhile, supply of potable water and fresh air underground is maintained," said spokesperson Nomzamo Khanyile.
