Ranking basis, ruled 7 Sep 2026. Assets are ranked only on a price-normalised after-tax NPV at 8% (npv8_price_normalised_usd_m), a Derived value read from each study's own published price-sensitivity table at a common deck (method: feed, npv8_price_normalised_method). npv8_common — discount-rate-normalised only — stays published and visible but is not a ranking basis, because gold-price bases across the cohort span US$1,500–4,000/oz. Assets without a price-normalised value list unranked, in name order. IRR is likewise not a sort basis: each study's IRR is at its own price deck and carries the same artefact. Capex sorts because it is an absolute Sourced figure, not a price-dependent one. Deck US$3,000/oz (re-ruled 7 Sep 2026). Nine assets carry the field (Assafou, Bankan, Afema, Doropo, Nyanzaga, Kobada, Bilboes, Kokoseb, Sanankoro). Every other gold row now says why it does not: 25 are not-applicable — every price point their study publishes lies below (or, for three recent studies, entirely above) the deck, so reaching it would be extrapolation the method forbids — and 4 are not-yet-verified, meaning no sensitivity point is on the feed and the study has still to be read. An empty cell here is a stated reason, not a gap.
Every bankability-complete asset on the platform, in one filterable view, across three hard-labelled confidence tiers. After-tax (DFS/PFS-grade) assets carry a single 8% real post-tax value (npv8_common) for comparability of discount rate only; ranking uses the price-normalised value where one exists. Pre-tax and PEA/scoping-grade assets sit in their own segregated sections below and are never ranked against after-tax figures or fed into any comparator. Every cell is driven live from the structured feed at /api/v1/bankability.json — this page holds no independent numbers.

| Asset | Stage | Issuer NPV (as reported) | NPV @ common 8% | IRR | Capex |
|---|
These assets' latest study reports pre-tax economics only. Pre-tax NPV structurally overstates value versus after-tax (no corporate tax, royalty or state-take deducted), so these are recorded on a hard-labelled separate tier, are excluded from npv8_common by rule, and are never ranked against the after-tax assets above.
| Asset | Stage | Pre-tax NPV (as reported) | IRR (pre-tax) | Capex |
|---|
These assets' best available economic study is PEA, scoping, or interim-economic-study grade — preliminary (typically ±35–50% accuracy), may include inferred resources, and cannot support a reserve declaration. They are lower confidence than the DFS/PFS-grade after-tax tier, so they are held on a hard-labelled separate tier, excluded from npv8_common and price_normalised by rule, and never ranked against after-tax or pre-tax assets. The tier relaxes study stage only — sourcing, vintage-matching, three-state labelling and the no-peak-price rule still apply, so a PEA at a flagged peak-price deck is still held, not banked.
