BHP says the estimated cost of the second phase of its Jansen potash mine in south Saskatchewan increases again, prompting a major write-down. In a company release, BHP reports that stage-two costs are expected to rise by more than US$2 billion to about US$6.9 billion. As a result of the updated cost outlook, BHP plans to record a writedown of roughly $2.3 billion related to the project. The cost increase reflects higher expected spending during the next phase of development for the mine, which is intended to expand production at the Jansen project. The reports from multiple Canadian outlets draw on BHP’s announcement, describing the same revised cost estimate and the associated accounting impact. The information is presented as forward-looking guidance from the company, tied to its assessment of project costs for the second phase. No details on funding, revised timelines, or operational changes are included in the excerpts provided.
