The head of South Africa's Association of Mineworkers and Construction Union (AMCU) said the group has agreed, in principal, to accept a new wage offer that could end a strike that has crippled the industry for months.
AMCU president Joseph Mathunjwa said Friday that the union had agreed to a deal with three major platinum producers.
However, the SAPA news agency reported, Mathunjwa added that there were still some issues that required consultation.
On Thursday, leaders of the Lonmin, Anglo-American Platinum and Impala Platinum companies proposed a plan that included a 20-percent wage increase for workers.
If accepted, the deal would end a five-month strike affecting about 70,000 workers.
The three mines normally account for about 40-percent of the global platinum output.
