Nigeria has signed a $1.3 billion agreement with the Africa Finance Corporation to construct an alumina refinery capable of processing one million tonnes of bauxite ore per year, in what the government is calling the country’s largest ever private sector investment in mining. The deal, signed in Abuja on 1 March through the Solid Minerals Development Fund, also covers a nationwide geoscience mapping programme and the creation of a joint investment vehicle to fast-track mineral exploration across the country.
The refinery will use a modern Bayer-process flowsheet and be powered by an on-site gas-fired cogeneration plant providing both steam and electricity. Designed to operate for 20 years at 95 percent utilisation, it is projected to produce 19 million tonnes of alumina over its lifespan. Government projections put the annual GDP contribution at $1.2 billion, total economic value at over $25 billion across the project lifecycle, and foreign exchange earnings at $8 billion. AFC and SMDF conducted joint feasibility studies ahead of signing that confirmed commercial viability and global cost competitiveness. The nationwide geoscience mapping exercise that accompanies the refinery deal addresses one of the deepest structural weaknesses in Nigerian mining: the absence of credible, publicly available geological data has consistently deterred exploration investment by making it impossible for companies to assess risk or target resources with any confidence.
Mines Minister Dele Alake described the deal as central to President Bola Tinubu’s agenda to reduce oil dependence by building a functioning solid minerals sector. SMDF executive secretary Fatima Shinkafi said the $1.3 billion capital commitment represented the largest project the fund had undertaken since its founding. The third component of the MOU establishes a joint strategic investment vehicle between AFC and SMDF specifically designed to accelerate development of exploration assets identified through the mapping programme, with both parties contributing capital and institutional capacity to move discoveries toward production faster than the standard licensing pathway allows.
Alumina is the intermediate product derived from bauxite that feeds aluminium smelters globally. Africa currently exports the vast majority of its bauxite as raw ore, capturing minimal value from a supply chain that terminates in finished aluminium products sold back to the continent at a significant premium.
The Bigger Picture Nigeria enters the alumina processing race at a moment when Guinea, which holds the world’s largest bauxite reserves, is also moving to build domestic refining capacity through a $1.2 billion SMB-Winning alumina refinery. The continental dynamic is shifting from raw ore export toward processing, driven partly by rising global aluminium demand and partly by African governments recognising how much value has been extracted without local capture. For Nigeria, the credibility test is execution: the country has announced large mining sector ambitions before without converting them into operating facilities. The geoscience mapping component is the more immediately consequential initiative because it generates the data foundation without which no refinery, however well-financed, can secure a reliable long-term bauxite supply.
