Whistler Project PEA: $2.00B NPV, 33% IRR
U.S. GoldMining Inc.'s Whistler Project in Alaska, USA (105 miles NW of Anchorage) has a Preliminary Economic Assessment (PEA) outlining an after-tax NPV of $2.00B, an after-tax IRR of 33%, and initial capital of $1.30B. The mine plan runs 14.6 years at about 183 koz Au per year.
U.S. GoldMining Inc.'s Whistler Project has reported Preliminary Economic Assessment (PEA) results for the gold-copper project in Alaska, USA (105 miles NW of Anchorage). The study headlines an after-tax net present value of $2.00B at a 5% discount rate. It reflects U.S. GoldMining Inc.'s (USGO) latest disclosed economics for the asset.
Economics. The after-tax NPV is $2.00B using a 5% discount rate. After-tax IRR is 33%. Initial capital expenditure is estimated at $1.30B. The study models a payback period of 2.1 years. All-in sustaining costs are pegged at 1046 USD/oz. Economics are based on Consensus: $3,200/oz Au, $4.50/lb Cu, $37.50/oz Ag; Spot: $5,000/oz Au, $5.85/lb Cu, $70/oz Ag.
Production and mine plan. The project envisions an open-pit operation. Life of mine is 14.6 years. Average annual production is approximately 183 koz Au. The open-pit strip ratio is 1.5:1 Y1-3.
Resources and ownership. Mineral resources: Indicated: 299.2 Mt @ 0.41 g/t Au, 1.90 g/t Ag, 0.15% Cu (5.41 Moz AuEq); Inferred: 290.8 Mt @ 0.47 g/t Au, 1.60 g/t Ag, 0.06% Cu (4.97 Moz AuEq). The company holds a 100% interest in the project. Royalties and streams: 3% NSR.

Our Analysis
The 33% after-tax IRR ranks in the upper half of our tracked universe and clears the practical financing hurdle for even a single-asset junior by a wide margin. However, the 5% discount rate used to report the $2.00B NPV is at the low end of convention, which inflates that headline figure—this is not a conservative assumption. The NPV sits at roughly 17.9x the company’s market cap, a gap that could signal the market has not yet priced in the project’s potential, but equally could reflect skepticism on financing, permitting, or jurisdictional risk.
Capital intensity is moderate at 65% of NPV, but the $1.30B initial capex is large relative to market cap, creating meaningful dilution risk for a developer. The study’s gold price assumption of $3,200/oz sits well below the current live spot of $4,135.70/oz, implying the returns are not dependent on today’s elevated prices and may have upside if costs are controlled. The single most important risk is funding: a junior with this market cap must secure over a billion dollars in a challenging equity and debt market, and any permitting delays would compound that pressure.
