The world’s biggest platinum miners won a reprieve after a South African court reserved judgment on whether to block a week-long industry strike that was scheduled to start Thursday night. The Association of Mineworkers and Construction Union called the action in sympathy with members at Sibanye Gold Ltd.’s gold mines, who downed tools over wages in November. Producers have warned the strike would hurt the industry, which is finally getting back on its feet as platinum-group metals recover. The threat of disruption has helped boost platinum and palladium prices this week.
