Every Afrimintel province score computes from the same formula. The formula is below. The inputs are below. The reconciliation lock blocks any build where the displayed score deviates from the computed score by more than ±0.05. Methodology and platform cannot drift apart silently.
Afrimintel was developed through April 2026 under the earlier working name STRATA. The platform is now launching publicly as Afrimintel. Audit log entries and technical reports dated before this release retain the STRATA reference as historical record.
African mineral assets carry a verification discount when they reach global capital. A DFI credit committee, a mining-finance desk, or a sovereign-wealth investment team applies a structural haircut to African geological data that does not exist for comparable data from Canada, Australia, or Chile. The discount is not a judgement on the geology. It reflects thinner verification chains — fewer historical NI 43-101 / JORC sign-offs, harder-to-reach primary sources, higher opacity on methodology.
Afrimintel is built to close that gap. Not cryptographically — no blockchain, no verifiable credentials, no distributed ledger. Those solve a different trust problem. Afrimintel closes the gap methodologically:
[VERIFIED], [INFERRED], [SPECULATED], or [UNKNOWN] tag. If a number is an inference, the reader sees it.This is the methodological claim. The test is whether it holds under challenge. The Corrections and Feedback section below carries a direct email for errors found by readers. If you find one, use it.
Afrimintel is an Africa-focused mineral intelligence platform covering 13 geological provinces and 40 countries. Current data inventory:
Afrimintel is currently in closed beta. No paid tier is available for purchase.
Records carry a machine-readable grade_class field assigning each to one of three tiers. Counts as of May 2026: 18 intelligence-grade · 6 research-grade · 88 spatial-reference · 112 total.
Criterion: Backed by a citable source (NI 43-101 Technical Report, JORC-compliant report, audited annual report, or named operator disclosure) with resource statement (tonnage + grade), named operator, and source document identifier.
Intended use: Citable as orientation in a professional context, subject to the reader's own verification against the primary filed document. Afrimintel is not QP-signed.
Criterion: Named operator and named primary-source citation (national mining survey body, government commerce department, or operator group), but without a published reserve/resource statement against an internationally recognised reporting code. Establishes existence and operator attribution beyond a coordinate, without claiming resource quantification.
Intended use: Orientation only; not citable for capital allocation. Use as the named-asset surface where the underlying jurisdiction does not file under NI 43-101 / JORC / S-K 1300. Currently populated by six Rwanda assets — Rutongo, Nyakabingo, Gatumba, Bugarama-Bukunzi, Musanze, NW Rwanda Gold Belt — sourced to the Rwanda Mines, Petroleum and Gas Board (RMB) and the US Department of Commerce Rwanda Mining Guide.
Upgrade path: A research-grade record graduates to intelligence-grade if and when a tonnage + grade statement under an internationally recognised reporting code becomes published.
Criterion: Name, coordinates, commodity, status, province only. No dossier.
Intended use: Map context showing where named deposits exist. Not actionable without primary-source research.
Afrimintel commits to quarterly review of intelligence-grade records:
/methodology/<record-name>-audit.mdlast_reviewed and next_audit_due fields; records past their next_audit_due render their INTELLIGENCE badge in amber with OVERDUE suffixFirst audit completed: Kamoa-Kakula (18 April 2026). Next audit due 18 July 2026.
Every audit MUST compare the Afrimintel record against the PRIMARY FILED DOCUMENT (NI 43-101 PDF on SEDAR+ or filer's website, JORC report, audited annual report). Summaries, press releases, and investor presentations may supplement the audit but NEVER substitute for the primary document.
Rationale: the first Kamoa audit (April 2026) was performed against a summary of the NI 43-101 rather than the filed PDF. This is a structural weakness — summaries drop nuance and can transcribe imprecisely. Future audits must open the primary PDF. The Kamoa record will be re-audited against the primary PDF at the next cycle to close this gap.
Where Afrimintel surfaces a Derived value computed by a tool — currently the DCF / NPV calculator — the tool itself is tested against a published input battery. The battery is published, not just the results, so any user, partner, or external reviewer can run the same tests and verify the tool independently.
The Day 30 v1.0 battery covers 15 tests across 5 categories (monotonicity, boundary, sensitivity, reconciliation, pre-specified failure mode), anchored to the Kamoa-Kakula Copper Complex DRC and its five published economic studies (Kakula DFS 2020 through Kamoa-Kakula 2023 IDP PEA — NPV targets spanning $5.5bn to $20.2bn).
The Q3 2026 expansion of the battery is scheduled for joint authorship with a named external mining-finance reviewer. The v2.0 battery will carry the reviewer's name and credentials alongside Afrimintel's.

(MSP × 0.6 + IC × 0.4) × Opportunity Multiplier within ±0.05 rounding tolerance. A pre-deploy reconciliation script runs against every build; any province whose displayed score deviates from its computed score by more than ±0.05 fails the build and blocks deploy. The methodology document and the platform implementation cannot drift apart silently — by design.
[VERIFIED] — confirmed from named citable source[INFERRED] — directionally likely, derived from related verified data[SPECULATED] — plausible but no direct evidence[UNKNOWN] — no reliable basisTags are applied at field level. A record tagged "intelligence-grade" may have individual sub-fields at [INFERRED] or [SPECULATED].
