BHP Group warned it will book a $2.3 billion charge at its Jansen Stage 2 potash project in Canada, the third time the company has blown past cost and time estimates for the two-stage development. Total investment for Stage 2 is now pegged at $6.9 billion, up from the $4.9 billion approved in 2023. First production has been pushed to the 2031 financial year.
The overrun hits BHP's effort to diversify beyond iron ore into potash and copper, a shift driven by the view that lower-carbon energy demand will reshape commodity markets. Potash, used in fertilizer, was meant to give BHP a counterweight to its iron ore business. That business generates most of its profit but faces long-term demand uncertainty from China's steel slowdown.
Jansen has been a problem from the start. Stage 1, approved in 2021, also ran over budget and behind schedule. The repeated misses raise questions about BHP's project execution at a time when the company is spending heavily on copper growth, including the $6.4 billion acquisition of Oz Minerals in 2023. Copper is the centerpiece of BHP's energy-transition bet. The Jansen experience suggests cost control is not a given.
The $2.3 billion charge will hit BHP's income statement in the second half of the fiscal year. The company has not said whether it will revise its capital expenditure guidance for the group. BHP's BHP stock page shows an Alpha Score of 66, reflecting moderate fundamental strength. The Jansen overrun adds execution risk to the story.
For the potash market, the delay means less new supply in the early 2030s. That is a modest positive for incumbent producers like Nutrien and Mosaic. They face a wave of new capacity from projects in Canada, Russia, and Belarus. Jansen's cost problems also signal that building new potash mines in Canada is getting more expensive. That could slow other greenfield projects.
BHP's iron ore and copper operations remain the profit drivers. The Jansen charge does not change that. It does make the diversification story harder to sell to investors who have watched the project bleed money for years. The next milestone is Stage 1 first production, expected in late 2026. If that also slips, the potash thesis gets weaker.
