SouthAfrica's Association of Mineworkers and Construction Union, or AMCU, warned thatit may bring Sibanye Gold Ltd.'soperations to a halt April 6, to protest against the company's three-year reached with otherunions in October 2015, News24Wire reported April 4, citing AMCU President JosephMathunjwa.

The newscame after a court ruled that the National Union of Mineworkers, Solidarity andthe United Association of South Africa could not protest the three-year wage deal.

"Wewill put Sibanye Gold to a standstill on Wednesday when we commence with the strike,"Mathunjwa was quoted as saying. AMCU demands a 12,500 South African rand monthlywage for its members.

The unionsaid earlier in February that it would serve a strike notice to Sibanye Gold because of the gold miner'sfailure to sign a separate wage agreement with the union.

However,the Labour Appeal Court rejected the union's application for the strike late inMarch as the group does not represent the majority of workers at the companies.

Mathunjwasaid AMCU was the majority at Sibanye Gold.
