Anglo American Platinum has agreed to reinstate the 12,000 South African miners sacked for taking part in an unofficial strike.
The National Union of Mineworkers said Amplats will take back the miners if they return to work by Tuesday.
The union said it expected all workers would return to their posts, which mean the end of the strike.
The strikers were sacked three weeks ago. Amplats said it was offering a one-off hardship payment of $US230 to facilitate their return.
Strikes at platinum, gold and coal mines are estimated to have cost South Africa more than $US1 billion since August.
