Donlin Gold Project PFS: $5.06B NPV, 10.3% IRR
NOVAGOLD Resources Inc.'s Donlin Gold Project in Alaska, USA has a Pre-Feasibility Study (PFS) outlining an after-tax NPV of $5.06B, an after-tax IRR of 10.3%, and initial capital of $9.23B. The proposed mine plan runs 27 years.
NOVAGOLD Resources Inc.'s Donlin Gold Project has reported Pre-Feasibility Study (PFS) results for the gold project in Alaska, USA. The study headlines an after-tax net present value of $5.06B at a 5% discount rate. It reflects NOVAGOLD Resources Inc.'s (NG.TO) latest disclosed economics for the asset.
Economics. The after-tax NPV is $5.06B using a 5% discount rate. After-tax IRR is 10.3%. Initial capital expenditure is estimated at $9.23B, with life-of-mine sustaining capital of $2.33B. The study models a payback period of 6.5 years. Economics are based on Gold Price (Cash Flow) $2,100/oz (long term gold price).
Production and mine plan. The project envisions an open-pit operation. Life of mine is 27 years. Metallurgical recovery averages 90%. The open-pit strip ratio is 6.5:1.
Resources and ownership. The company holds a 60% interest in the project. Royalties and streams: Calista Lease: NSR of 1.5% for earlier of first five years following commencement of commercial production or until initial capital payback, converting to 4.5% NSR thereafter; net proceeds royalty of 8% of net proceeds. TKC SUA: milled tonnage fee of $0.40/t processed for first 10 years, converting to $0.50/t thereafter; net proceeds payment of 3%. No Government royalty obligations..
These figures are extracted from NOVAGOLD Resources Inc.'s technical disclosures and reflect the most recent PFS on file.

A 10.3% after-tax IRR does not clear the bar that project lenders actually apply. Developers typically need roughly 15% to attract project finance, and 20%-plus where the developer is a higher-risk junior with little else in the portfolio, which is the situation here: this is the only project we track for this company. Against the 119 gold projects in our set, that return ranks above just 1% of them. Payback of 6.5 years sits below every one of the 103 projects we track on that measure. On the numbers as filed, this does not get financed on its own merits.
The valuation line tells a different story, and the gap is the whole tension. After-tax NPV of $5.06B ranks above 99% of the 193 gold projects we track, and that figure is roughly 1.6x the company's US$3.08B market cap. But the initial capex is $9.23B, about 3x the entire market cap and 183% of NPV, lower than every one of the 176 projects we track on that ratio. A company of this size cannot quietly fund a build several times its own equity value. The NPV is real on paper; the funding path to it is not obvious, and the market's discount may reflect exactly that.
Two things could change the arithmetic. The study assumes $2,100/oz gold against a live spot of $4,200.70/oz, so the filed economics are built well below today's market, and a sustained higher price would lift the returns materially. Failing that, a partner, a sell-down, or a smaller staged build would be needed to close the gap. Note also that this is a pre-feasibility study, which narrows estimates to roughly a plus or minus 25% band but is not yet a build decision, and the figures are unchanged from the 2025 PFS across NPV, capex, mine life and IRR. The question that decides this project: can a US$3.08B company finance a $9.23B build in Alaska, or does it need someone else to?
