The agreement is an important step in implementing the US PGM operations’ plan to fully mechanise its mining, including a move away from a rock-breaking incentive to a team-based incentive and modernising certain legacy benefits that were out-of-scope with the United States market.

Strike action by members of the USW at the Stillwater East mine and Columbus metallurgical facility continues. The Company remains committed to constructive engagement to reach an agreement that enables long-term sustainability of the operations.
