Africa's Critical Minerals: What the Continent Has, Who Controls It, and the Investment Opportunity

Africa holds approximately 30% of all critical mineral reserves globally, the metals and materials that power electric vehicles, smartphones, wind turbines, and defence systems. The concentration at the commodity level is even more striking: the continent accounts for over 70% of global cobalt production (the Democratic Republic of Congo alone), approximately 80% of the world's platinum group metal reserves (overwhelmingly South Africa), and 67% of global phosphate reserves (overwhelmingly Morocco). As the global energy transition accelerates demand for these materials, Africa has become the world's most strategically important resource frontier, and the site of an intensifying geopolitical contest between China, the United States, and the European Union.

Here is the part that most coverage misses: Africa extracts the minerals but captures almost none of the value chain. Fewer than 5% of critical minerals are refined or processed locally in Africa before export, according to Zero Carbon Analytics. China dominates 85% of global processing capacity for critical minerals and 60% of worldwide production. The DRC's copper is 93% refined outside the country. Zambia refines 1.3% of its copper locally. The gap between Africa's reserve position and its processing capacity is both the continent's strategic vulnerability and its most interesting investment thesis for the next decade.

Africa's share of global critical mineral reserves

Some specifics worth knowing. The Kalahari Manganese Field in South Africa's Northern Cape contains approximately 4.2 billion tonnes, equivalent to over 77% of all land-based manganese reserves on Earth. South Africa processes 76% of the world's platinum and holds roughly 80% of known PGM reserves, with 67% of global annual PGM production. Morocco's OCP Group controls 31% of global phosphate rock production and 49% of phosphoric acid. These are not marginal positions, they are structural monoarchies in critical commodity markets.

Why critical minerals are the new oil

The energy transition has a materials problem. A single electric vehicle requires up to 8 kg of lithium, 35 kg of nickel, 20 kg of manganese, and 10-15 kg of cobalt (depending on battery chemistry). Wind turbines need rare earth elements. Solar panels need silicon and silver. The International Energy Agency projects that demand for lithium will grow 40 times by 2040; cobalt demand will grow sixfold; nickel and manganese will roughly double.

These are not substitutable in the short term. Battery chemists are working to reduce cobalt content per cell, but cobalt-free batteries are not yet dominant at scale. Platinum group metals are non-substitutable in catalytic converters (for conventional vehicles), hydrogen fuel cells, and the industrial processes that make green ammonia and green hydrogen economically viable.

Africa's position in this supply chain is analogous to Middle East oil producers in the 1970s, with one critical difference. The major oil producers controlled their own production and pricing (through OPEC). Most of Africa's critical mineral production is controlled by foreign companies, primarily Chinese. The policy question facing African governments is how to change that balance of power before the window closes.

DRC: cobalt ground zero

The Democratic Republic of Congo produces over 70% of global cobalt output. This is not a statistic that will change quickly, the Katanga and Lualaba provinces contain ore bodies with no equivalent elsewhere on earth. What has changed is who controls those ore bodies and under what terms.

Chinese companies control approximately 72% of cobalt and copper mines in DRC, according to AidData analysis and Tearline intelligence reporting from December 2025. The two most significant operations:

Tenke Fungurume (TFM): CMOC (China) holds an 80% stake, acquired from Freeport-McMoRan for $2.65 billion in 2016. In 2023, TFM produced 280,297 tonnes of copper and 21,592 tonnes of cobalt. CMOC paid $800 million to resolve a royalty dispute with the DRC government in April 2023, an indication of the DRC government's increasing assertiveness about capturing resource rents.

Sicomines: Chinese companies hold 68%, DRC state 32%. 2023 output was 206,612 tonnes of copper. A new $7 billion infrastructure-for-minerals deal was signed in January 2024.

DRC's export embargo and quota system

In February 2025, the DRC imposed a full export embargo on cobalt concentrates. By October 2025, the embargo was replaced with a quota system, a signal that the government wanted revenue without fully choking the industry. The quotas:

Source: Bankable Africa, October 13, 2025

The quota system creates a striking gap between production and permitted sales. CMOC extracted 61,073 tonnes of cobalt in H1 2025 alone, against a full-year quota that permits sales of approximately 26,000 tonnes. The company can produce at full speed but cannot legally sell much of what it mines, a constraint that affects global cobalt supply, cobalt prices, and the economics of DRC mining for any non-state-connected operator.

For investors: the DRC's willingness to use production quotas as a policy tool introduces regulatory risk into any cobalt investment thesis. CMOC's scale provides some protection through its relationship with the DRC government. Smaller operators face greater exposure.

The artisanal mining dimension

Approximately 15 to 25% of DRC's cobalt output comes from artisanal and small-scale mining (ASM), involving an estimated 150,000 to 200,000 individual miners. The ESG implications for supply chains are significant: documented cases of child labour and unsafe conditions in ASM sites have prompted battery makers and automakers to demand traceability from their cobalt suppliers. Any investor or corporate buyer sourcing cobalt from DRC needs a credible supply chain traceability system. The Responsible Minerals Initiative (RMI) and equivalent frameworks provide the audit infrastructure, but compliance requires active management.

Zimbabwe: lithium's rising power, and a sudden policy reversal

Zimbabwe exported 1.128 million metric tonnes of spodumene concentrate in 2025, an 11% year-on-year increase, making it Africa's largest lithium producer and one of the world's fastest-growing suppliers. The country holds Africa's largest lithium reserves.

On February 25, 2026, the Zimbabwe government banned all raw mineral and lithium concentrate exports effective immediately, accelerating a policy originally planned for January 2027, according to Reuters reporting from February 25, 2026. The ban is explicit about its intent: force in-country processing and value addition, replicating Indonesia's successful nickel export ban model.

The model has precedent. Indonesia banned raw nickel ore exports in 2020, initially at enormous cost to government revenues and in defiance of WTO complaints. By 2025, Indonesia had become a significant nickel processing hub, with Chinese companies building smelters and refining facilities to comply with the new regime. Zimbabwe is betting on the same dynamic.

Processing investment was already underway before the ban:

The February 2026 ban caught exporters mid-shipment in some cases. The near-term market impact includes tighter lithium supply and potential upward price pressure. The investment implication: companies with in-country processing capabilities in Zimbabwe are now in a structurally stronger position than those that relied on exporting raw concentrate. The winners from Zimbabwe's ban are lithium processors, not miners.

South Africa: platinum group metals and the irreplaceable position

South Africa's Kalahari Manganese Field and its PGM deposits are in a category of their own. The country processes 76% of the world's platinum and holds approximately 80% of known PGM reserves, with the Bushveld Complex in the North-West and Limpopo provinces as the anchor.

PGMs matter beyond jewellery. Platinum and palladium are the primary active materials in automotive catalytic converters, which are required for emissions compliance in conventional internal combustion engine vehicles. Platinum is also a key catalyst in proton exchange membrane (PEM) electrolysers for green hydrogen production, a sector with substantial projected growth. South Africa's 67% share of global annual platinum production makes the country structurally essential to both the transition away from fossil fuels and to hydrogen as an alternative fuel.

South Africa produces 71.5% of global platinum and 42.7% of global chromium. The mining sector directly employs 474,736 people, contributes approximately 6% of GDP directly, and earns a further 9% through indirect linkages. Mining company market caps on the JSE rose 28% in 2025, according to PwC's SA Mine report.

The constraint on South Africa's mining sector is not reserves, it is infrastructure. Rail and port capacity bottlenecks limit export volumes by an estimated 15 to 20%, according to industry analysis. Transnet, the state logistics company, signed a 25-year partnership with ICTSI of the Philippines for Durban Container Terminal Pier 2 in December 2025, which should improve port throughput over the next three to five years. The rail bottleneck remains more complex.

Tanzania: graphite rising

Tanzania is positioning as a significant natural graphite supplier through two projects that are moving from development into production:

Lindi Jumbo (Walkabout Resources, ASX: WKT): Capacity of 40,000 tonnes per year, reserves of 5.5 million tonnes, 24-year mine life, 290 employees. The first commercial consignment shipped in May 2024 to India's battery and anode sector. Annual output targets are ramping up through 2025 and 2026, according to TanzaniaInvest reporting from June 2025.

Epanko Graphite Project: Updated feasibility study completed February 27, 2026, showing a net present value of $516 million at target output of 73,000 tonnes per year.

Natural graphite is the primary material in EV battery anodes. China currently supplies approximately 65 to 70% of global natural graphite. Tanzania's emergence as a competing supplier is commercially significant for battery makers seeking to diversify their supply chains away from Chinese concentration.

Namibia: uranium at record production

Namibia produced 7,333 tonnes of uranium oxide (U3O8) in 2024, a record high, representing approximately 10% of global uranium supply and making Namibia the world's third-largest uranium producer, according to The Oregon Group and Min-Met reporting.

Three producing mines:

• Husab (Swakop Uranium; majority-owned China General Nuclear Power Group): 4,000 to 5,000 tonnes per year
• Rossing (CNNC, China National Nuclear Corporation): 2,200 to 2,500 tonnes per year
• Langer Heinrich (Paladin Energy 75%): restarted 2024 after care-and-maintenance period

The China concentration is notable: 77% of Namibia's uranium was exported to China in 2023. This matches the pattern visible in cobalt, copper, and lithium, where Chinese state and commercial entities have invested in African resource extraction while maintaining processing and enrichment capacity at home.

The nuclear power expansion underway in China, India, and several other Asian markets is driving sustained uranium demand. Uranium prices hit multi-decade highs in 2024. Namibia's producers are the principal beneficiaries, though the dominance of Chinese-owned operations means most of the value accrues to Chinese rather than Namibian shareholders.

Morocco: phosphate superpower

Morocco controls 67% of the world's total phosphate reserves, approximately 50 billion metric tonnes, and OCP Group, the state-owned operator, is the world's largest phosphate producer. OCP's 2024 metrics:

• Revenues: $9.76 billion
• Production: 30 million metric tonnes
• Global market share: 31% of phosphate rock, 49% of phosphoric acid, 23% of finished fertilizers

Source: OCP Group annual reporting

Phosphate is the foundation of global food security: it is a primary ingredient in fertilizer, and no synthetic substitute exists. Reducing dependence on imported fertilizers is a strategic priority for food-importing nations. Morocco's position in global food supply chains is therefore not merely commercial, it is geopolitically significant.

OCP has been expanding into fertilizer production (downstream processing of phosphate rock into finished products), moving up the value chain rather than exporting raw rock. This is the model African governments are trying to replicate across the minerals sector: capture more value before export.

The value chain gap: Africa's core strategic problem

Africa's dominant reserve position has not translated into commensurate economic returns because the value in critical minerals accrues in processing, not in mining. The sequence: raw ore worth $X per tonne → refined metal worth 3 to 5 times more → finished battery component worth 10 to 20 times more → EV battery pack worth 30 to 50 times more.

Africa captures value at the first step and occasionally the second. China captures value at every step from the second onward. The gap:

• DRC copper: only 7% refined locally
• Zambia copper: 1.3% local refining
• Africa-wide: fewer than 5% of critical minerals processed locally before export

Source: Zero Carbon Analytics, November 2025

The arithmetic is stark. DRC earned approximately $11 billion from copper and cobalt exports in 2023. If those minerals were refined and processed domestically, the revenue could be three to five times higher. The gap between what Africa earns and what it could earn is roughly $30 to $50 billion per year across the sector, more than the continent receives in total foreign direct investment from China ($3.37 billion in 2024).

The African Green Minerals Strategy and policy response

The African Union adopted the African Green Minerals Strategy (AGMS) at its 38th Ordinary Session in February 2025. The strategy has four pillars: advancing mineral development, developing people and technology, building key value chains, and mineral stewardship. It is rooted in the African Mining Vision of 2009 and explicitly targets the shift from raw material exporter to value-added participant, according to African Green Minerals reporting from February 2026.

Whether AGMS produces results depends on implementation at the national level. Zimbabwe's February 2026 export ban is the most aggressive national-level implementation of the value addition principle anywhere on the continent. DRC's quota system is a more cautious version of the same logic. Zambia is negotiating with copper refiners to expand local processing capacity.

The fundamental obstacle is China's processing dominance. China controls 85% of global processing capacity for critical minerals, built over 30 years with deliberate state investment. African governments cannot build equivalent capacity in a decade without either Chinese investment (which may perpetuate the same dynamic) or Western financing at a scale that has not materialised.

China vs. the US and EU: the geopolitical competition for African minerals

China's position: Chinese companies control 72% of DRC cobalt and copper mines. Total BRI investments in Africa exceed $160 billion. Chinese FDI in Africa was $3.37 billion in 2024, down 15% from the prior year but still the largest single-country source, according to SAIS-CARI data. China controls or operates over 40 African ports across 32 nations.

The US response has been the Minerals Security Partnership (MSP), a coalition of 14 countries and the EU, and a series of MOUs with Angola, Zambia, Botswana, and DRC on critical minerals. The Lobito Corridor, Angola to DRC and Zambia, is explicitly positioned as a US-EU counter to China's infrastructure investments, linking the Zambian and DRC copper belt to an Atlantic port. US DFC committed $550 million to the project; the US pledged $4 billion total by December 2024, according to Reuters reporting from April 2025.

The awkward data point: US FDI in Africa in 2024 was negative $2.02 billion on a net basis, according to Stimson Center analysis from February 2025. American companies are not deploying capital at anywhere near the scale needed to compete with China's established positions.

The EU's Critical Raw Materials Act (CRMA), adopted December 2023, targets 10% domestic extraction, 40% processing, and 15% recycled CRMs by 2030. Critics have pointed out that the CRMA prioritises EU domestic processing over African beneficiation, using African raw materials to build EU processing capacity rather than supporting African value addition, according to SWP Berlin analysis from February 2026.

Country investment climate: where to look

DRC: The highest-risk, highest-reward jurisdiction. Chinese operators have established relationships and the necessary political risk tolerance. Western investors have largely retreated since the Freeport-McMoRan sale in 2016. The quota system adds a new layer of regulatory uncertainty. Most accessible entry points for outside investors are through publicly listed majors: Glencore (LSE: GLEN, which holds Mutanda), and CMOC (Hong Kong: 3993).

South Africa: The most investor-friendly mining jurisdiction on the continent. JSE-listed miners (Anglo American Platinum: AMS, Impala Platinum: IMP, Sibanye-Stillwater: SSW) offer liquid, IFRS-compliant, dividend-paying exposure to PGMs. The main risk is Eskom (largely resolved) and Transnet's port-and-rail infrastructure constraints.

Zimbabwe: High potential, high political risk. The February 2026 export ban is a positive signal for in-country processors but a negative for exporters. Chinese-backed processing investments (Arcadia, Bikita) are the main activity. Foreign investors outside China face a more difficult entry point.

Namibia: Uranium producers are largely Chinese or Australian-listed. Paladin Energy (ASX: PDN) holds 75% of Langer Heinrich, offering Western-capital-accessible exposure to Namibian uranium production.

Morocco: OCP Group is state-owned and not publicly listed, limiting direct investment access. Indirect exposure through fertilizer companies that source from OCP.

Tanzania: Walkabout Resources (ASX: WKT) is the most accessible listed vehicle for Tanzanian graphite exposure.

Frequently asked questions about Africa's critical minerals

What critical minerals does Africa have that the world needs?

Africa holds approximately 55 to 56% of global cobalt reserves (DRC dominant), 80 to 92% of platinum group metal reserves (South Africa dominant), 67% of global phosphate reserves (Morocco dominant), 62% of global chromium reserves, and 25 to 36% of natural graphite. These minerals are essential components in electric vehicle batteries, catalytic converters, hydrogen fuel cells, solar panels, and agricultural fertilizer. The continent as a whole holds approximately 30% of all critical mineral reserves globally.

Who controls cobalt mining in the DRC?

Chinese companies control approximately 72% of cobalt and copper mine production in the DRC by volume, according to AidData and Tearline analysis. CMOC (China) holds 80% of Tenke Fungurume, which produced 21,592 tonnes of cobalt in 2023. Glencore (Swiss/UK) operates the Mutanda mine. The DRC government introduced a quota system in October 2025, limiting CMOC to 6,500 tonnes per quarter of cobalt exports, substantially below its actual production run rate of over 120,000 tonnes annually.

What is Zimbabwe's lithium export ban and why does it matter?

On February 25, 2026, Zimbabwe banned all exports of raw minerals and lithium concentrates with immediate effect, according to Reuters. The ban was designed to force in-country processing and value addition, following the model of Indonesia's 2020 nickel export ban. Zimbabwe is Africa's largest lithium producer, exporting 1.128 million metric tonnes of spodumene concentrate in 2025. The ban affects all exporters of raw concentrate and creates a structural advantage for companies with in-country processing facilities, including Zhejiang Huayou Cobalt's $400 million plant at Arcadia Mine and Sinomine's $500 million pledged investment at Bikita.

Why does Africa control so many critical minerals but remain poor?

The core reason is the processing gap. Fewer than 5% of Africa's critical minerals are refined or processed locally before export, according to Zero Carbon Analytics. The raw ore exported from DRC or Zambia is worth a fraction of the refined metal, battery component, or manufactured product it eventually becomes. China captures most of the value-added processing chain: it controls 85% of global processing capacity and 60% of global critical mineral production. Africa earns from extraction; China earns from transformation. The African Green Minerals Strategy (adopted by the AU in February 2025) explicitly targets changing this through mandatory beneficiation requirements.

What is the African Green Minerals Strategy?

The AGMS is an African Union framework adopted at the AU's 38th Ordinary Session in February 2025. It has four pillars: advancing mineral development, developing human and technological capacity, building value chains, and mineral stewardship. Its explicit objective is to shift Africa from a raw material exporter to a value-added participant in global critical mineral supply chains. It is the policy framework underpinning national-level measures like Zimbabwe's export ban and DRC's quota system. Whether it produces results depends on implementation capacity and the political will to maintain beneficiation requirements in the face of pressure from mining companies and trading partners.
