Commodity Price Convention

What commodity-price reference Afrimintel uses for DCF inputs, and where the platform explicitly does NOT produce a price deck.

METHODOLOGY v1.0 9 MAY 2026

Why this page exists. Any DFI credit committee reading the platform's DCF input mapping tables will ask "where do your prices come from." This page documents the platform's price-input convention explicitly so that question has a structured answer rather than an inferred one. The page also flags the boundaries of platform price-deck capability — the institutional users requiring proprietary price-decks are directed to incumbent sources rather than implied to receive them from the platform.

1. The platform's price-input convention

Afrimintel does not publish a proprietary commodity price deck. The platform's DCF tool and DCF input mapping tables on case-study dossiers reference commodity prices through three explicit conventions:

ConventionWhat it meansWhere it applies
1. LME official prices (spot reference)For copper, nickel, zinc, lead, aluminium: London Metal Exchange official cash settlement prices. Public, dated, citable. Used as spot reference, not as forward forecast.Cu / Ni / Zn / Pb / Al base-metals references in DCF input mappings
2. London gold AM/PM fix (gold reference)For gold: London Bullion Market Association AM/PM fix. Public, dated, citable. Used as spot reference.Au references in Loulo-Gounkoto DCF input mapping
3. Operator / industry-aggregator published indicative levelsFor lithium spodumene SC6, cobalt, manganese, REE: indicative levels published by Argus Media, Fastmarkets, Mysteel, or operator filings (e.g. Lithium Royalty Corp's December 2025 Goulamina valuation at $1,300/t SC6 long-term consensus per Citi Research). Public, dated, citable. Cited with attribution.Battery-minerals references in Manono / Kabanga DCF input mappings

Each DCF input mapping table on the case-study dossiers (Kabanga, Manono, Loulo-Gounkoto, Lobito, Kamoa-Kakula) carries explicit price ranges drawn from the conventions above with dated reference points; institutional users running scenarios should substitute their own price assumptions per their internal price deck.

2. Where Afrimintel does NOT produce a price deck

The platform does not produce:

Institutional users requiring proprietary price decks should consult:

The platform's positioning is depth-over-breadth on Africa-focused asset-level decision-aid; commodity-price-deck capability is structurally different work that the incumbent platforms above produce at scale.

3. How DCF input mapping tables use price inputs

The DCF input mapping tables on each case-study dossier carry price columns formatted as ranges, not single point estimates. The ranges are intended to be reproducible scaffolding — institutional users substitute their own price decks and observe the NPV signal direction across the range.

Example pattern (from Kamoa-Kakula DCF input mapping):

ScenarioCu price ($/lb)Source convention applied
Pre-compression reference$3.10/lb real (2020 DFS basis)Operator-disclosed primary source (Ivanhoe 2020 Kakula DFS)
Post-compression base case$4.00-4.50/lbLME current spot range (Convention 1)
Conservative (margin-stress)$3.50/lbLong-term consensus reversion; institutional-user judgment
Optimised FS upside$4.50/lbSustained current; institutional-user judgment

The convention applied is documented; the institutional-user judgment scope (where applicable) is named explicitly. The platform does not assert price forecasts; it provides reproducible scaffolding for institutional users running sensitivity analysis.

4. Quality Standard mapping

Per the platform's three-state Quality Standard:

Three-state classificationHow price inputs are classified
SourcedLME / LBMA fix / operator-disclosed historic price (Convention 1, 2, partial 3) — named, dated, citable primary source
DerivedSpot range applied as DCF input scenario — Afrimintel calculation explicitly framed as "current spot range"; institutional-user-judgment substitution scope named explicitly
AbsentMulti-year forward price forecasts — explicitly NOT produced by Afrimintel; institutional users directed to proprietary price-deck sources above
