Africa is a geological giant that is still largely unknown. While the continent hosts 30% of the world's critical mineral reserves essential for the energy transition, it has only attracted 10% of global exploration spending in 2024. For example, Botswana, the world's largest diamond producer by value, has only explored 30% of its territory. This under-exploration is due to the prohibitively high cost and high risk of failure of the initial prospecting stages, factors that often discourage private companies from engaging without prior guarantees.

To reverse this trend, several nations have decided to take the initiative by becoming the architects of their own geological knowledge. Botswana has thus announced the creation of a public exploration company. In the midst of a diamond crisis, Gaborone is using this tool to prove to the world its potential in copper and nickel, thereby accelerating the diversification of its revenue.

For its part, Nigeria is deploying an aggressive strategy to break free from its historical dependence on oil. By multiplying strategic partnerships, notably with the Africa Finance Corporation and France, Abuja is working to map out a subsoil whose reserves are estimated at $700 billion. In East Africa, Kenya has taken a major technological step with a national airborne geophysical campaign. This initiative has already identified 970 mineral occurrences across 15 counties, supporting the national ambition to increase the contribution of mining to GDP from 1% to 10% by 2030.

Investing in exploration enables states to break the information asymmetry that disadvantaged them in contract negotiations. As Botswana's Minister of Mines, Bogolo Joy Kenewendo, has emphasized, having accurate data prevents "losing a lot of money" by exploring blindly. A state that knows the true value of its subsoil no longer negotiates a simple "license of hope" but presents a documented project, increasing its chances of attracting serious investors for sustainable exploitation.

However, technical mastery of data is not enough. To transform these mineral indicators into productive exploitations, states must combine this knowledge with regulatory and fiscal stability. The global battle for critical minerals has begun, and African nations that can marry documented geological potential with a transparent legal framework will be the big winners of the global energy transition.
