Northshore Property (Peter Mitchell Mine) Feasibility Study: $619M NPV Over a 48-Year Mine Life
Cleveland-Cliffs Inc.'s Northshore Property (Peter Mitchell Mine) in St. Louis County, Northeastern Minnesota, USA (Mesabi Iron Range) has a Feasibility Study outlining an after-tax NPV of $619M. The mine plan runs 48 years at about 5 MLT wet pellets/y per year.
Cleveland-Cliffs Inc.'s Northshore Property (Peter Mitchell Mine) has reported Feasibility Study results for the iron ore (magnetite taconite / iron ore pellets) project in St. Louis County, Northeastern Minnesota, USA (Mesabi Iron Range). The study headlines an after-tax net present value of $619M at a 10% discount rate. It reflects Cleveland-Cliffs Inc.'s (CLF) latest disclosed economics for the asset.
Economics. The after-tax NPV is $619M using a 10% discount rate. Economics are based on US$98/WLT Pellet (three-year trailing average revenue); Mineral Reserves evaluated at US$90.42/LT wet standard pellet freight-on-board (FOB) Lake Superior; Mineral Resources optimized using US$90/LT pellet value.
Production and mine plan. The project envisions an open-pit operation. Life of mine is 48 years. Average annual production is approximately 5 MLT wet pellets/y. Average head grade is 24.6% MagFe (crude ore). Metallurgical recovery averages 29.4%. The open-pit strip ratio is 0.8 waste units to 1 crude ore unit.
Resources and ownership. The company holds a 100% interest in the project.
These figures are extracted from Cleveland-Cliffs Inc.'s technical disclosures and reflect the most recent Feasibility Study on file.

Against the 527 projects we track, this one lands in the upper half on after-tax NPV of $619M, ahead of 51% of that universe. That is a precise place to start, and it is a useful one: the asset is better than the median project we cover, but the margin is thin. There is no step-change here, no valuation gap that forces the market's hand. What an investor is buying is a solid mid-table project, and the return case has to be made on execution rather than on the number itself.
The constraint that matters most is not the returns, it is the scale of the company against the scale of the build. This is one of 15 projects we track for a US$6.96B mid-cap, and the after-tax NPV sits well below that market cap on a rough currency-adjusted basis. That relationship cuts the other way from the usual lament: the asset is not large enough to move the equity on its own, and it is competing for capital inside a diversified portfolio where management can fund it, defer it, or sequence it behind other priorities. A 48-year mine life in St. Louis County on the Mesabi Iron Range is a genuine jurisdictional positive, a established US mining district with permitting precedent, and it is production-stage rather than a greenfield concept.
The study itself is feasibility-level, the build-ready estimate carrying roughly a plus or minus 15% band, so these numbers deserve more weight than a scoping exercise would. The price assumptions are internally consistent, a three-year trailing average of US$98/WLT for revenue, with reserves at US$90.42/LT and resources optimised at US$90/LT. The question that decides this one: does a mid-table NPV inside a 15-project portfolio justify the capital and management attention, or does it stay a long-dated option?
