Many African nations still don’t fully know what minerals lie beneath their soil — a problem rooted in history and politics. While Rwanda has made deliberate efforts to map and manage its resources, Ghana remains largely dependent on private mining companies for geological knowledge.
For centuries, colonial powers extracted Africa’s mineral wealth without sharing detailed geological data. Even today, archives in London, Paris, and Brussels hold much of this information, rather than the capitals of the resource-rich countries themselves.
Ghana, Africa’s top gold producer, earned $11 billion from minerals in 2024. It also has diamonds, manganese, bauxite, and newly discovered lithium. Yet, it lacks comprehensive geological surveys. Frequent changes in government — power tends to alternate between two parties every eight years — discourage long-term projects like mapping. Instead, mining companies conduct their own surveys, often without oversight, and don’t always share results. Political elites also benefit from opaque licensing systems, giving them little incentive to push for transparency.
Rwanda, rich in tin, tantalum, tungsten, and other minerals, has taken a different approach. Since the mid-2000s, the Rwandan Patriotic Front has invested in long-term resource planning. It reformed mining laws, created its own state-owned exploration company (Ngali Mining), and directly hired geological firms to map its resources. Between 2012 and 2016, it commissioned extensive surveys and reorganized its mining zones into 52 well-defined exploration areas, making it easier to attract investors.
Even Rwanda faces challenges. The country earns quick cash by importing minerals — especially gold — from the Democratic Republic of Congo and re-exporting them. While this boosts foreign exchange, it risks sidelining deeper investment in domestic resource exploration.
With global demand for critical minerals surging, African nations face a choice: continue relying on incomplete or foreign-held geological data, or invest in mapping their resources for long-term gain. But this isn’t just a technical challenge — it’s political. Unless governments break the cycle of short-term incentives and opaque deals, their mineral wealth will remain under their feet but out of their control.
