Johannesburg - North West premier Thandi Modise on Sunday urged parties involved in wage negotiations at Impala Platinum to return to mediation in good faith.
"The framework agreement for a sustainable mining industry should guide the wage negotiation process and adherence to the framework of the law and established structures of collective bargaining," she said in a statement.
"Strengthening the mining sector to set it on a sustainable footing requires management and labour to engage each other to find win-win solutions instead of screaming threats at each other."
The Association of Mineworkers and Construction Union (Amcu) on Friday said it would consult its members on a possible strike after it received a certificate to strike at Impala when wage negotiations deadlocked.
Amcu treasurer Jimmy Gama said the union had received a strike certificate after it deadlocked on negotiations.
The strike certificate required Amcu to give the mine 48 hours' notice before embarking on strike action.
Amcu was demanding a basic salary of R12 500 a month for underground workers and R11 500 for surface workers, with benefits, he said.
In a statement on Friday, Impala said it had been engaged in a mediation process with Amcu, facilitated by the Commission for Conciliation, Mediation, and Arbitration (CCMA).
