Our Analysis

IRR after-tax
35%

higher than 56% of 297 projects we track

NPV after-tax
$43M

At 35% after-tax IRR, the project ranks in the upper half of the 297 all commodities projects we track, and comfortably clears the ~15% after-tax return developers typically need to finance a build. Its after-tax NPV is below the company's market capitalisation (roughly 0.4x, on a currency-adjusted basis) — a modest slice of the company's value, as you'd expect for one asset in a larger portfolio. The project is located in Nevada, USA, a factor in its overall risk profile.

Our take, benchmarked against the project economics in the Mining Stocks database. Figures are estimates drawn from company technical reports — not investment advice; always verify against the source filing.
