Sibanye Stillwater will be forced to halt operations at its Montana palladium mine if prices don’t recover soon, according to CEO Neal Froneman.

“The future of Stillwater remains in the balance,” the CEO said on Tuesday, when asked at a London conference about the outlook for the mine. “I mean it’s as simple as that. If there’s no correction in the price soon, as strategic as it is, we will have to put it on care and maintenance.”
