Our Analysis

At 48% after-tax IRR, the project ranks in the top quartile of the 292 all commodities projects we track, and comfortably clears the ~15% after-tax return developers typically need to finance a build. Its after-tax NPV is well above the company's market capitalisation (roughly 126.5x, on a currency-adjusted basis) — a wide gap that can flag value the market hasn't yet priced — though dilution, financing and permitting risk usually explain part of it. Initial capital runs to about 32% of project NPV, making it capital-light; funding that build is the central execution risk. A modelled payback of 2.5 years is moderate for a project of this type. The project is located in Thunder Bay, Ontario, Canada, a factor in its overall risk profile.
