Impala Platinum has promised to take a hard line on loss-making projects, especially if metal prices continue to decline.
The operations that are at the highest risk notably include the Royal Bafokeng Platinum assets, which the Implats group only recently acquired following a protracted tussle with Northam Platinum.
Implats, which reported its annual results on Thursday, is feeling the impact of lower platinum group metal prices - a basket of which has already fallen 20% in the year to date - while economic growth prospects and the metal demand outlook remain uncertain.
Briefing stakeholders on the group's performance, Implats CEO Nico Muller said the company would not tolerate cash losses from any of its operations.
"When I look at operations that are at risk, certainly RBPlat is going to require a lot of attention in order to get the cost of operations to the position that we aspired to when we made the offer for the company 18 months ago," he said, noting that the business has experienced double-digit cost increases in the past year.
