Data Integrity
Methodology & Data Confidence
ADVISORY PANEL
The Afrimintel methodology and data quality are reviewed by a panel of domain experts. Advisory panel members do not influence commercial decisions or client relationships.
Field Corrections Programme
Afrimintel accepts field corrections from verified exploration professionals. Corrections are reviewed, applied, and attributed by name. Field corrections submitted by senior exploration geologists working on live African projects are examples of this process.
To submit a field correction: nikesh@afrimintel.com
Advisory Panel — Building
Afrimintel is currently forming its advisory panel. Panellists are domain experts in African economic geology, DFI mineral investment, and geophysical survey practice. Enquiries: nikesh@afrimintel.com
INDEPENDENCE POLICY
Afrimintel is an independent intelligence platform. Province scores, IC assessments, data verification tags, and AI analysis outputs are produced without commercial consideration from exploration operators, mining companies, equipment vendors, or governments whose jurisdiction data appears in the platform.
Marketplace listings are not paid placements. Province scores are not negotiable. Data partner relationships do not influence scores or editorial content. AI-generated analysis is not approved by featured companies before publication.
This policy is permanent.
What Afrimintel measures, how it measures it, and what you must verify before citing it
PROVINCE SCORES
Afrimintel scores are editorial constructs — not peer-reviewed indices.
Formula: (MSP × 0.6 + IC × 0.4) × Opportunity Multiplier
MSP (Mineral System Potential): Afrimintel editorial assessment of geological prospectivity, based on published BGS/USGS survey data, academic literature, and NI43-101 deposit density. Not peer-reviewed.
IC (Investment Climate): Sourced from Fraser Institute Annual Survey IAI where available (year stated). Weights (0.6/0.4) reflect standard exploration industry emphasis on geology over policy — Afrimintel editorial.
Opportunity Multiplier: Editorial multiplier reflecting current market timing. Range 1.05× – 1.30×.
⚠ Do not cite Afrimintel province scores in professional documents without disclosure that scores are editorial constructs. Present as "Afrimintel Intelligence Index" not as an independently validated metric.
DATA CONFIDENCE LABELS
[VERIFIED]
Confirmed from a named, citable public source. Year of verification stated where possible.
[INFERRED]
Directionally reliable from multiple sources but not confirmed from a single citable document. Verify before citing.
[SPECULATED]
Plausible estimate with no confirmed source. Use only for orientation. Never cite.
KNOWN DATA LIMITATIONS
Market capitalisations: Removed from all operator profiles — figures become stale within days. Use exchange/ticker links for live data.
LTIFR (safety rates): Removed from ESG scorecards — figures require direct access to each company's published sustainability report. Check company website.
EITI compliance: Afrimintel removed fabricated numerical EITI scores. EITI publishes only: Compliant / Candidate / Suspended / Not member. Verify at eiti.org.
Supply-demand projections: [INFERRED] from published reports (BMI, CRU, IEA). Cobalt projections particularly volatile given LFP battery chemistry adoption. Verify against current reports before citing.
Comparable transactions: ~28 verified transactions. Always verify deal terms against primary source (press release, filing) before citing in IC memo or professional document.
Bilateral programme budgets: Figures are estimates — verify at programme source pages (links provided in each entry).
Geographic coverage: Afrimintel has deep intelligence on 13 geological provinces. Deposit data exists for 40 countries but intelligence depth varies significantly — primary countries have far greater coverage than secondary ones.
PARTNERSHIPS IN PROGRESS
The following data quality improvements are pending partnership responses:
• BGS Africa Programme — identified as primary data partnership target. Status: outreach in dialogue (May 2026) — initial response received from BGS leadership; email follow-up underway. No partnership confirmed. If confirmed in future, would enable validated geological survey data integration across multiple provinces.
• Fraser Institute — will confirm citation arrangement for current-year IAI values with exact survey date
• AfDB ANRC — will enable live project pipeline data replacing static entries
• USGS Mineral Resources — will confirm MRDS citation format and Africa dataset notifications
