Understanding Africa’s unrivalled position in the global supply chain for lithium, cobalt, copper, and rare earth elements — and what it means for long-term investors.
The energy transition has many faces. It appears in the solar panels installed on residential rooftops in Germany, in the electric vehicles rolling off assembly lines in Shanghai, and in the grid-scale battery storage facilities being commissioned across the American Southwest. But behind every one of these technologies lies the same foundational reality: they require minerals, and those minerals are disproportionately located in Africa.
Sub-Saharan Africa alone holds an estimated 30 percent of the world’s critical mineral reserves. The continent is home to roughly 80 percent of global platinum and chromium, 47 percent of cobalt, 85 percent of manganese, and significant deposits of lithium, graphite, copper, and rare earth elements. As global supply chains for these materials tighten under the pressure of surging demand, the continent holding the world’s largest reserves is drawing unprecedented institutional attention.
The Scale of Global Demand
The numbers are unambiguous. According to the International Energy Agency’s Global Critical Minerals Outlook for 2025, lithium demand rose by nearly 30 percent in 2024 alone — far exceeding the ten percent annual growth rate of the previous decade. Demand for nickel, cobalt, graphite, and rare earth elements each grew by six to eight percent in the same year, driven almost entirely by energy applications: electric vehicles, grid storage, solar infrastructure, and the data centres underpinning the artificial intelligence economy.
Looking further out, the trajectory is steeper still. By 2040, the world will require 4.5 times as much lithium as it currently produces, and more than twice as much graphite. In copper, the supply gap is particularly concerning — declining ore grades, rising extraction costs, and a sharp slowdown in new discoveries are creating a structural deficit that traditional producing regions cannot fill on their own.
The Democratic Republic of Congo, the world’s single largest cobalt producer, accounts for more than 70 percent of global supply of that mineral. Zambia is targeting three million tonnes of copper output by 2031 — a figure that would reshape global copper trade. Zimbabwe and Namibia are positioning themselves as lithium processing hubs. Tanzania holds graphite deposits actively sought by industrial processors. These are not speculative opportunities. They are the foundation on which the global energy transition will be built.
The Concentration Problem — and the Opportunity
The challenge in critical minerals markets is not simply one of geography. It is one of processing. China controls approximately 90 percent of global refining capacity for critical minerals, including material mined elsewhere. For graphite and rare earth elements, the IEA projects that even by 2035, China will supply more than 80 percent of the refined, battery-grade output the world requires. This concentration creates systemic vulnerability in global supply chains and is driving an urgent and well-funded effort by Western governments and private capital to develop alternative sources.
Africa sits at the centre of this effort — but extracting value from that position requires more than geology. It requires capital, infrastructure, processing capability, and governance. These are precisely the conditions that create opportunity for patient, structured investors who are willing to build alongside local operators and institutional development partners, rather than extract and exit.
At least 13 African countries have enacted export restrictions since 2023, seeking to move up the value chain from raw mineral export to processed output. Morocco inaugurated its first lithium-ion battery materials manufacturing plant at Jorf Lasfar in 2025. The Africa Finance Corporation and the African Development Bank have financed the Lobito Corridor — a regional infrastructure network linking the DRC, Angola, and Zambia to global shipping lanes. These developments signal that Africa is not simply a supplier in the minerals story. It is increasingly a participant in the value chain.
What Serious Investment Looks Like
For institutional investors serious about critical minerals, Africa demands a particular kind of engagement. The standard playbook of financial modelling and due diligence is necessary but insufficient. What differentiates successful investors in African resource markets is the quality of their operating relationships, their understanding of jurisdictional nuance, and their ability to structure transactions in ways that align incentives across governments, communities, operators, and capital providers.
Projects in Namibia, Botswana, Rwanda, and parts of Zambia and Tanzania offer clear mining codes, investment protection treaties, and improving infrastructure. The common characterisation of African mining as uniquely risky obscures a more nuanced reality: the investors who are generating superior returns are doing so because they understood the market before others did, built the right partnerships, and structured their positions for the long term.
Capital deployed into mine-tied processing infrastructure, renewable energy solutions for remote operations, and supply chain logistics often generates returns that isolated extraction projects cannot match. The opportunity is not simply to participate in the minerals boom. It is to own the infrastructure through which the boom flows.
Conclusion
The race for critical minerals is the defining resource story of the next two decades. The energy transition, the AI economy, and the defence modernisation programmes of every major power depend on reliable, diversified access to materials that are concentrated in Africa in quantities found nowhere else on earth.
For long-term investors who understand the continent, who have built the operational relationships and the capital structures to execute, Africa is not a frontier market in the pejorative sense. It is the most strategically important resource destination on the planet. The race begins here.
