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.
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 (W/O).
Resources and ownership. The company holds a 60% interest in the project. Royalties and streams: Calista Lease: NSR 1.5% for first five years or until initial capital payback, converting to 4.5% NSR; net proceeds royalty of 8%. TKC SUA: milled tonnage fee $0.40/t for first 10 years, $0.50/t thereafter; net proceeds payment of 3%. No government royalty obligations..

A 10.3% after-tax IRR does not clear the bar that matters. Project financiers typically want roughly 15% to lend into a development, and 20%-plus where the developer is a higher-risk junior with little else in the portfolio, which is the case here: this is the only project we track for this company. Against the 115 gold projects in our database, that return ranks above just 1% of them. A 6.5-year payback, longer than every one of the 96 projects we track on that measure, tells the same story. On the numbers as published, this does not get financed on its own merits.
The oddity is that the headline looks enormous. After-tax NPV of $5.06B ranks above 99% of the 154 gold projects we track, and that is roughly 1.6x the company's US$3.26B market cap. But the discount rate is 5%, the low end of the reporting convention, and the NPV is being generated by a very long 27-year schedule rather than by strong early economics. The market's apparent indifference to a $5.06B NPV against a $3.26B market cap cuts both ways: it can mean the asset is unrecognised, or that investors are discounting financing, dilution, permitting in Alaska, and the sheer scale of the build. The second reading is the more defensible one.
Scale is where this gets hard. Initial capex of $9.23B is 183% of NPV, lower than every one of the 149 gold projects we track on that ratio, and about 2.8x the company's entire market cap. A company cannot quietly finance a build worth nearly three times its equity value. That points to a partner, a sell-down, or a much larger owner. The study itself is a PFS, a plus or minus 25% estimate, not a build decision. The one thing that changes the arithmetic is price: the study assumes $2,100/oz gold against a live spot of $4,424.90/oz. Whether that gap survives into a feasibility-level cost estimate is the question that decides this project.
