Zondereinde mine in South Africa remains shut for a 17th day after Northam Platinum failed to reach a deal over wages with the workers' union.
The demands of the workers include a 15% basic wage increase, higher allowances and changes to payment categories, all equating to a 32% rise per worker, which has been rejected by the company.
The company's revised offer of a 9% basic wage increase was rejected by the miners through a vote.
About 80% of Northam's 6,800 employees at its Zondereinde mine have been on strike since 5 September.
The strike is costing about $1.28m in revenue losses a day, said Northam.
Zondereinde mine produces about 1,000oz of metal including platinum, palladium, rhodium and gold a day.
