BHP to Book $2.3 Billion Charge After Jansen Potash Project Overruns

Cost Overruns and Delays at Jansen Potash Project

Background and Project Acceleration

June 18 (Reuters) - BHP Group on Thursday warned of cost overruns at its Jansen Stage 2 potash project in Canada and said it will book a $2.3 billion charge as higher costs and additional labour hours drive up spending and delay first production.

This is the third time BHP has blown past its cost and time estimates for the two stages of the project, dealing a major setback to the miner's decade-long plans to diversify from copper and iron ore.

Reasons for Overruns

BHP accelerated the development of Jansen in 2022 on bets that the Russia-Ukraine conflict would disrupt fertiliser supply and boost prices. But inflation, design changes and lower productivity drove up costs and delayed first output.

"It is noted that cost and schedule pressures are driven by inflationary and real cost escalation, design development and scope changes, lower productivity outcomes and additional labour hours and material quantities to complete," BHP said in its statement.

Financial Impact and Future Outlook

Its total investment estimate for the project's second stage is now expected at $6.9 billion, up from $4.9 billion approved in 2023. First production is now expected in late financial year 2031.

The first stage is expected to cost $8.4 billion, nearly 50% higher than what was approved in 2021, and remains on track to begin production in mid-2027.

As a result of the cost overruns, BHP said it will recognise an impairment charge of about $2.3 billion for the potash project. It maintained its annual capital expenditure forecast at $11 billion for 2027 financial year.

The firm said that Stage 2 is 16% complete as of May-end and is expected to deliver around 4.36 million metric tons per year.

The combined output of the project after a two-year ramp-up would be about 10% of total global potash production, BHP said.

Key Takeaways

  • Stage 2 investment estimate rises to US$6.9 billion from the US$4.9 billion approved in 2023, representing a US$2 billion increase due to inflation, design changes, productivity challenges and extra labour and materials (bhp.com).
  • BHP will book an impairment charge of approximately US$2.3 billion, reflecting the third time cost and schedule targets for the Jansen project have been exceeded (bhp.com).
  • Stage 1 costs have also climbed, with the total investment now at US$8.4 billion (up from US$5.7 billion at approval), although first production remains on track for mid‑2027; Stage 2 is 14–16% complete, now expected to begin production in late FY 2031 (bhp.com).
