Its pre-tax NPV is above the company's market capitalisation (roughly 1.4x, on a currency-adjusted basis) — a wide gap that can flag value the market hasn't yet priced — though dilution, financing and permitting risk usually explain part of it. The project is located in Nevada, USA, a factor in its overall risk profile. For context, gold currently trades around $4,131.50/oz.

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.
