Serra Norte Complex Resource Estimate: $19.55B NPV, $8.06B Capex
Vale S.A.'s Serra Norte Complex in Brazil has a Mineral Resource Estimate outlining an after-tax NPV of $19.55B and initial capital of $8.06B.
Vale S.A.'s Serra Norte Complex has reported Mineral Resource Estimate results for the iron ore project in Brazil. The study headlines an after-tax net present value of $19.55B at a 7.01% discount rate. It reflects Vale S.A.'s (VALE) latest disclosed economics for the asset.
Economics. The after-tax NPV is $19.55B using a 7.01% discount rate. Initial capital expenditure is estimated at $8.06B, with life-of-mine sustaining capital of $8.06B. All-in sustaining costs are pegged at 44.2 US$/ton of product. Economics are based on Long-term price of US$92.3/dmt for 62% iron grade.
Production and mine plan. The project envisions an open-pit operation. Metallurgical recovery averages 97.3%.
Resources and ownership. The company holds a 100% interest in the project. Royalties and streams: Royalties: 5.5 US$/ton of product (opex); total royalties US$ 7,994 M over LOM.
These figures are extracted from Vale S.A.'s technical disclosures and reflect the most recent Resource Estimate on file. Compare this project against other developers and producers in our project economics database, and always verify the numbers against the original technical report before making any investment decision.

Our Analysis
- NPV after-tax
- $19.55B
higher than 100% of 360 projects we track
- Initial capex
- $8.06B
41% of NPV
costlier than 100% of 376 projects we track
- Study price assumption
- Long-term price of US$92.3/dmt for 62% iron grade
The NPV ranks above all 360 projects we track, and the capex sits at the bottom of the pack at 41% of NPV, lower than every one of the 376 peers. Those are not modest positions; they are the top and bottom of our entire database. But the rank is a function of scale, not efficiency. This is a $19.55B NPV on an $8.06B build, which means the asset is enormous and the capital required to unlock it is comparatively small. The funding risk is the sharpest signal here: the build cost is roughly 0.1x the company's US$63.79B market cap, so this is a project a large-cap can finance from its own balance sheet without breaking a sweat. That combination, top-quartile NPV and negligible funding strain, is rare and should be read as the core of the investment case.
The constraint is the stage. This is a Resource Estimate, not a feasibility study, so the economics are indicative at best. The NPV and capex figures carry none of the engineering confidence that a PEA or DFS would provide. Brazil is a mining-friendly jurisdiction with a deep iron ore history, which lowers the political risk profile, but the absence of a formal economic study means the headline numbers could shift materially once actual mine plans, metallurgy and infrastructure costs are tested. The long-term price assumption of US$92.3/dmt for 62% iron grade is the key sensitivity; if realized prices settle below that, the NPV compresses faster than the capital-light structure suggests.
The two-sided read on the valuation gap is straightforward. A $19.55B NPV against a $63.79B market cap implies the market is not assigning full value to this asset, but it also implies the company is already large enough that this project, even at full value, is a meaningful but not transformative piece of the equity. The question that decides whether this works is not whether the ore is there, it is whether the resource estimate survives the transition to a bankable study without the economics deteriorating. Everything else, the rank, the funding ease, the jurisdiction, is supportive. That single step is the risk.
