IN SHORT: Nigeria’s Solid Minerals Development Fund and the Africa Finance Corporation signed a landmark MOU in early March covering a $1.3 billion alumina refinery, a nationwide geoscience mapping programme, and a joint strategic investment vehicle for mineral exploration. The refinery, which will process one million tonnes per year for a 20-year operating life, is expected to be Nigeria’s largest-ever private mining investment and to contribute $25 billion to GDP over its lifetime.
Nigeria has signed its largest ever mining investment deal, a $1.3 billion alumina refinery backed by the Africa Finance Corporation that will process one million tonnes of alumina annually for export, as the government accelerates its push to transform the country’s under-monetised solid minerals sector into a credible second revenue pillar alongside oil.
The MOU between the Solid Minerals Development Fund and AFC was signed in Abuja in early March, with Mines and Steel Development Minister Dele Alake confirming that all regulatory approvals on the government side have been granted.
- The refinery is designed around a one million tonne per year processing capacity, operating over a 20-year lifespan and producing a total of 19 million tonnes of alumina output. The project includes an on-site gas-fired cogeneration power plant to ensure energy supply independent of the national grid, a longstanding constraint on industrial investment in Nigeria.
- AFC has committed to lead and co-arrange the project financing. The corporation, which has a balance sheet of more than $10 billion and a mandate to finance transformative African infrastructure, has framed the deal as part of its industrial investment strategy targeting value-added mineral processing rather than raw commodity export.
- The MOU also covers two additional components: a nationwide geoscience mapping exercise that will produce the first comprehensive updated geological survey of Nigeria’s mineral endowment since the 1970s, and the creation of a joint strategic investment vehicle for ongoing mineral exploration across the country. The mapping programme alone is expected to unlock significant new investment by providing the baseline data that international mining companies require before committing exploration capital.
- The economic projections are substantial: the government’s figures put the refinery’s contribution at $1.2 billion per year in GDP impact and $8 billion in foreign exchange earnings over its operating life, for a cumulative $25 billion GDP contribution across the 20-year period.
- Nigeria has significant bauxite deposits but has historically exported raw ore rather than processed alumina, capturing only a fraction of the value chain. The refinery reverses that by moving Nigeria up the processing stack, a model the government explicitly cites as analogous to what Morocco has done with phosphate processing through OCP.
- The deal builds on AFC’s expanding role in Nigeria. The corporation co-arranged the $4 billion Dangote Refinery syndicated debt package and has been one of the most active infrastructure financiers in the country over the past five years.
Minister Alake described the signing as a turning point for Nigeria’s solid minerals sector, adding that the government’s ambition is to position mining as a genuine diversification pillar that can generate foreign exchange revenue at scale independent of crude oil prices.
The Bigger Picture: Nigeria has been talking about mining diversification for 40 years. What is different now is that the Tinubu administration has paired the rhetoric with regulatory action: clearing approvals, signing MOUs with credible financiers, and framing the sector in terms of the revenue targets that matter to a government navigating a post-subsidy fiscal adjustment. AFC’s involvement is the key credibility signal. The corporation does not sign MOUs on projects it does not intend to finance. If the refinery gets built, it establishes a template for value-added mineral processing that Nigeria can replicate across iron ore, lithium, and the other solid minerals sitting largely unmonetised in its subsoil.
