Congo–Belgium transfer of colonial geological records: key points for mine planners
Reviewed by Tom Sullivan

30 Second Briefing
Congo and Belgium have agreed a joint roadmap to digitise and restitute millions of colonial-era geological records held at the Royal Museum for Central Africa in Tervuren, covering surveys, maps, drill logs and exploration reports from 1885–1960. EU-funded digitisation is already under way, with digital copies being sent in batches to Congolese authorities, who see the archive as key to locating new copper, cobalt, lithium, tin, tungsten and uranium deposits beyond current mining districts. The move sidelines KoBold Metals’ bid for privileged access, keeping control of the dataset with public institutions rather than a single AI-driven explorer.
Technical Brief
- Digitisation work at the Royal Museum for Central Africa is already underway using EU funding streams.
- Belgian authorities insist public scientific collections cannot be granted exclusive access rights to KoBold Metals.
- Digital datasets are being transferred in batches to specified Congolese government recipients rather than industry partners.
- The archive spans colonial-era work from 1885–1960, covering multiple exploration campaigns and survey generations.
- DR Congo’s endowment cited includes copper, cobalt, lithium, coltan, tin, tungsten, gold and uranium resources.
- KoBold’s 2025 agreement with Congo covers digitising historical geological data and applying AI-driven targeting algorithms.
- BHP and Eramet are separately funding or partnering with early-stage tech explorers to apply data-centric discovery methods.
Our Take
With DR Congo already flagged in our database as a major source of smuggled coltan and artisanal gold via North Kivu, formal access to Belgium’s colonial-era geological records could strengthen the state’s hand in delineating legitimate cobalt, copper and coltan reserves versus conflict-affected areas.
For critical minerals like cobalt, copper and lithium, historical Belgian datasets combined with KoBold Metals’ 2025 AI-driven exploration agreements in DR Congo are likely to accelerate target generation, potentially shifting exploration focus from well-known Copperbelt zones to underexplored terrains mapped pre‑1960.
