DR Congo's mineral mapping race to reshape cobalt supply

The Democratic Republic of Congo has launched a nationwide airborne mineral mapping programme designed to sharpen knowledge of its vast underground wealth and pull fresh exploration capital into regions that investors have largely ignored. The initiative, announced in Kinshasa at the start of this week, aims to give the Central African nation its most detailed picture yet of where commercially valuable deposits could lie beneath some of the least surveyed terrain on the planet.

The timing matters because the country already dominates the supply chains that power the energy transition. The Democratic Republic of Congo is the world's largest cobalt producer and Africa's top copper producer, two metals essential for electric vehicle batteries, consumer electronics and renewable energy infrastructure. Yet officials say less than 10% of its territory has been thoroughly explored, leaving enormous gaps between the country's reputation and what geologists actually know about its subsurface.

The mineral mapping effort comes as Kinshasa tightens its grip on the mining sector. In recent years the government has pushed for a bigger share of revenues from existing operations while extending state control over the geological information that underpins future discoveries. By owning better data, authorities hope to negotiate from a position of strength when foreign companies come looking for licenses.

Millions of kilometers of flight lines

The mineral mapping project, known as PC2G-RDC, will use high-resolution airborne geophysical surveys to improve geological knowledge of the country's subsurface. The National Geological Service of the Congo, known by its French acronym SGNC, is implementing the programme with technical support from the Spanish geophysics company Xcalibur. According to a statement issued on Monday, survey work will concentrate on the Kongo Central, Kwango, Kwilu and Greater Kasai regions, building on mapping already completed in Greater Katanga, the country's historic mining heartland.

Mines Minister Louis Watum Kabamba told attendees at the launch that the programme would expand the country's geoscientific coverage to 46.1% from 22.27%, effectively doubling the share of territory covered by modern datasets. The 36-month campaign will deploy eight aircraft to collect magnetic, radiometric, gravimetric and electromagnetic data across roughly 35% of national territory through more than 3M kilometers of flight lines.

Officials stress that airborne surveys on their own will not confirm any deposits. Geological anomalies spotted from the air still require follow-up ground exploration, interpretation by trained geologists and, where results warrant it, drilling before anyone can say whether mineralisation exists in commercially viable quantities. The data simply lowers the uncertainty and risk that companies face before committing capital to exploration.

Kinshasa wants to own its own data

With the mineral mapping survey under way, the government is framing the effort as a question of sovereignty as much as economics. SGNC director-general Raoul Wazenga Vitima said sovereignty begins when the state knows its territory, owns its maps, controls its data, preserves its samples and trains the experts capable of interpreting that information. "Congo should not only be better mapped; it should increasingly be capable of mapping itself," he added, according to Reuters reporting on the launch.

The modernised datasets are expected to identify new prospective areas and strengthen the state's capacity to plan and negotiate resource development. For mining companies, better maps mean fewer expensive surprises. For the government, they mean harder questions for investors: if Kinshasa knows what lies underground, it can demand terms that reflect the true value of its resources rather than the guesses of foreign prospectors.

Analysts watching the sector say the programme could matter well beyond Congolese borders. Cobalt prices have swung wildly in recent years as battery makers weighed supply risks, and any credible new pipeline of deposits could reshape expectations across the industry. Still, the path from an airborne anomaly to an operating mine typically takes many years, so the mineral mapping campaign now under way is a long-term bet rather than an instant fix for tight markets.

For now, the planes are in the air and the data is flowing. If the project delivers on its promise, the Democratic Republic of Congo will enter the next round of mining negotiations holding something it has never fully held before: a detailed, modern and state-owned picture of its own underground wealth.
