BHP Group's Jansen Potash Project (Stage 1) in Canada / Saskatchewan has a Pre-Feasibility Study (PFS) outlining an after-tax NPV of $5.50B and an after-tax IRR of 15.2%.
BHP Group's Jansen Potash Project (Stage 1) has reported Pre-Feasibility Study (PFS) results for the potash project in Canada / Saskatchewan. The study headlines an after-tax net present value of $5.50B at a 6.5% discount rate. It reflects BHP Group's (BHP) latest disclosed economics for the asset.
Economics. The after-tax NPV is $5.50B using a 6.5% discount rate. After-tax IRR is 15.2%. Economics are based on Potash price of US$338/t.
Production and mine plan. The project envisions an underground (long room and pillar) operation. Average head grade is 25.6% K2O (resource), 24.9% K2O (reserve). Metallurgical recovery averages 92%.
Resources and ownership. The company holds a 100% interest in the project.

A 15.2% after-tax IRR places this potash project in the bottom quartile of the 304 projects we track, yet its $5.50B NPV ranks in the top 1% of 360. That split is the entire investment thesis in miniature: this is a very large, very low-return asset. The rank tells an investor that the IRR is essentially at the practical financing hurdle for project debt, not above it. For a project of this scale, that means the economics are acceptable but offer no margin for error in construction costs, schedule, or potash prices. The NPV rank is a function of sheer size, not efficiency, and size cuts both ways: it is a meaningful addition to a large-cap balance sheet, but it is also a build that must be financed and executed without the cushion of a higher return.
The funding picture is the constraint that matters most. With a market cap of US$218.22B, the project's NPV sits well below the company's equity value, which removes the financing risk that would sink a junior. A build of this size can be absorbed internally or through normal large-cap capital markets, and the company's portfolio breadth means a single-asset failure is not existential. But the PFS stage, with its roughly plus or minus 25% estimate band, is not a build decision. The gap between a 15.2% IRR and the financing hurdle is thin enough that a modest cost overrun or a softer-than-assumed potash price of US$338/t could push the project below the threshold where debt becomes available on reasonable terms.
The jurisdiction, Saskatchewan, is a stable mining environment, and the commodity's long-term demand profile supports the scale of the resource. The question that decides whether this works is execution: can a large-cap developer deliver a project of this magnitude at a cost that preserves an IRR already sitting at the financing margin? If yes, the NPV is real and the project is a portfolio anchor. If not, the low return rank means there is little room to absorb the miss.
