Data Sources Catalogue

Where the data comes from

Country-level geological survey infrastructure, cadastral systems, geophysical coverage, geochemistry, remote sensing layers, and contacts — the operational data substrate Afrimintel sources from in each jurisdiction where mineral activity warrants country-level depth.

Eleven tier-1 and tier-2 African mineral jurisdictions are catalogued below at full operational depth. Each entry names: the national geological survey body, the cadastre, the geophysics (aeromagnetics, gravity, MT, geochemistry, satellite), the mineral targets, the data portal URL, and the contact. Tier-1 jurisdictions have national-systematic data coverage comparable to Australian state surveys; Tier-2 have substantial coverage with documented gaps. Mineral provinces and country-level coverage for the remaining 29 jurisdictions in Afrimintel's 40-country coverage are surfaced on the Country Intelligence pane at lighter depth.

Methodology note. The data sources named here are public-record geological survey infrastructure. Afrimintel does not assert exclusive access to any source listed; everything tagged FREE is freely retrievable by any user, everything tagged CONTACT requires direct request to the named organisation. Afrimintel's editorial value is in the curation, the cross-referencing against deposit dossiers and province scoring, and the discipline architecture (Quality Standard tagging, audit log, correction velocity SLA) — not in proprietary data extraction. Where a source carries an Derived flag, the platform notes that the inclusion of the source is editorial inference (typically based on published organisational scope) rather than primary-source verification. The full source-citation discipline is documented in the Quality Standard.

Pending v1.3. Spatial-reference deposit tier expansion to ~500 entries via USGS MRDS African subset — deferred to Q3 2026 prospectivity engine cohort per the deferred roadmap.
