Pretoria - Talks between platinum producers and union Amcu to resolve the 12-week-long wage strike are expected to continue on Wednesday, the Chamber of Mines said.

"There is no update... the meeting is expected to continue tomorrow," said spokeswoman Charmane Russel on Tuesday.

Anglo American Platinum (Amplats) and Implats have presented Amcu with the new offer in a bid to end the three-month-long strike in the platinum sector.

The proposed increases would ensure that the minimum cash remuneration (comprising basic wages and holiday, living out and other allowances) for entry level underground employees rises to R12,500 per month (R150,000 per annum) by July 2017.

Amcu members at Impala, Lonmin and Amplats operations in Rustenburg in North West and in Northam in Limpopo downed tools on January 23 demanding a basic salary of R12,500 per month.

The union previously rejected a wage increase of up to nine percent. The companies, in turn, rejected Amcu's revised demand that the R12,500 could be phased in over four years.

The 12-week strike had so far resulted in R6 billion in employees' lost earnings and R14 billion in companies' revenue lost, according to the Chamber of Mines' website.
