OEM-Miner Supply Deals — Automaker Mineral Strategies & Offtake Agreements

A New Procurement Model

The global automotive industry is undergoing a fundamental transformation in how it procures raw materials. For a century, automakers operated at the end of a long supply chain, purchasing finished components from Tier 1 suppliers without direct engagement with the mining companies that produced the underlying materials. Steel, aluminium, and rubber were commodity inputs managed through trading houses and spot markets. The automaker's relationship with the mine was, at most, three or four intermediary steps removed.

The battery electric vehicle has demolished this model. The cobalt, lithium, nickel, copper, and rare earth materials in an EV battery pack are too strategically important, too supply-constrained, and too geopolitically sensitive to be left to commodity markets and intermediary traders. Automakers are now signing multi-year, multi-billion-dollar offtake agreements directly with mining companies—securing guaranteed supply volumes at predetermined prices or pricing formulas, often accompanied by pre-payment, equity investment, or technical partnership provisions.

This shift represents the most significant change in automotive procurement since the industry's founding. Automakers that once viewed raw materials as somebody else's problem are now deploying dedicated mining and mineral teams, investing directly in exploration and mine development, and competing with each other for access to finite mineral resources. The 4x demand multiplier ensures that this competition will intensify through the decade.

Tesla’s Mineral Strategy

Tesla has been the most publicly visible automaker in securing direct mineral supply agreements, reflecting both its scale as the world's largest EV manufacturer and its corporate culture of vertical integration.

Tesla-Glencore Cobalt

Tesla signed a significant cobalt supply agreement with Glencore, sourcing material from Glencore's DRC operations including the Mutanda and Kamoto mines. The deal was structured as a multi-year offtake agreement covering approximately 6,000 tonnes of cobalt per year, with provisions for volume adjustments based on Tesla's production requirements. Notably, Tesla signed this agreement even while publicly committing to reduce cobalt usage in its batteries—a pragmatic acknowledgment that even reduced-cobalt chemistries require substantial volumes at Tesla's manufacturing scale.

Tesla-Prony Resources Nickel

Tesla signed a nickel supply agreement with Prony Resources, operator of a nickel-cobalt processing facility in New Caledonia. The deal aimed to secure Class 1 nickel from a non-Indonesian, non-Russian source, diversifying Tesla's nickel supply away from geopolitically complex jurisdictions. The agreement included provisions for Tesla to support the environmental rehabilitation of the Prony Resources mine site.

Tesla Lithium Refining

In a distinctive vertical integration move, Tesla began constructing its own lithium refining facility in Corpus Christi, Texas, designed to produce battery-grade lithium hydroxide from imported spodumene concentrate. This facility, if operational at scale, would make Tesla one of the few automakers with in-house mineral refining capability, reducing its dependence on Chinese lithium processing. Tesla has also acquired lithium clay deposit rights in Nevada, though the timeline for development remains unclear.

Tesla-BHP Nickel

Tesla signed a nickel supply agreement with BHP covering production from BHP's Nickel West operations in Western Australia. The deal emphasises sustainable mining practices and traceability, with BHP providing nickel sulfate processed using renewable energy at its Kwinana refinery. This agreement represents the type of high-ESG, non-Chinese mineral sourcing pathway that Western automakers are increasingly pursuing.

European OEM Deals

BMW

BMW has been among the most proactive European automakers in establishing direct mine-to-factory supply chain visibility. Key agreements include cobalt sourcing from CMOC's DRC operations (Tenke Fungurume and Kisanfu), lithium supply from Livent (now Arcadium Lithium) in Argentina and Australia, and nickel supply from BHP and other diversified miners. BMW has implemented digital traceability systems to verify that its cobalt supply meets responsible sourcing standards, including independent audits of mine-site conditions.

Volkswagen Group

Volkswagen, through its battery subsidiary PowerCo, has signed a series of mineral supply agreements to feed its planned European gigafactories in Salzgitter, Valencia, and St. Thomas (Canada). VW-Glencore agreements cover cobalt supply from DRC operations. VW has also invested in lithium projects in Canada and has signed nickel offtake agreements with multiple producers. The company's strategy emphasises long-term fixed-price contracts to hedge against the mineral price volatility that has plagued battery cost projections.

Mercedes-Benz

Mercedes-Benz has secured direct supply agreements for cobalt (from Glencore), lithium (from Rock Tech Lithium and other producers), and has invested in battery recycling ventures to secure secondary material supply. Mercedes's approach emphasises responsible sourcing certification and has included provisions for mine-site social impact programs as part of its offtake agreements.

Stellantis

Stellantis, the parent company of Jeep, Peugeot, Fiat, and other brands, has signed agreements with Controlled Thermal Resources for lithium (from the Salton Sea geothermal brine project in California), Vulcan Energy for lithium (from geothermal brine in Germany), and multiple nickel and cobalt producers. Stellantis has also entered a binding offtake agreement with Alliance Nickel for nickel-cobalt supply from Australia.

US OEM Strategies

General Motors

GM has been the most aggressive US-headquartered automaker in securing mineral supply. Key agreements include a lithium deal with Livent (Argentina), a cobalt and nickel deal with Glencore (including DRC cobalt), a lithium deal with Lithium Americas (for the Thacker Pass mine in Nevada), and an equity investment in Controlled Thermal Resources. GM has also partnered with its battery joint venture partner LG Energy Solution on joint mineral procurement, leveraging combined purchasing volume to negotiate favourable terms.

Ford

Ford has signed lithium supply agreements with Albemarle, Compass Minerals, and SQM, as well as nickel agreements with BHP and Vale. Ford has notably shifted its battery strategy multiple times, initially planning high-NMC content and subsequently pivoting toward increased LFP adoption for its standard-range vehicles. This chemistry flexibility requires maintaining supply relationships across both cobalt-nickel (for NMC) and lithium-iron-phosphate supply chains.

Asian OEM Approaches

Toyota

Toyota Tsusho, the trading arm of the Toyota Group, has been active in securing mineral supply for Toyota's planned battery electric and hybrid vehicle production. Toyota Tsusho holds interests in lithium brine projects in Argentina and has cobalt supply relationships with DRC producers. Toyota's mineral strategy is notable for its emphasis on diversified chemistry options—the company is simultaneously developing NMC, LFP, and solid-state battery programs, requiring supply flexibility across multiple mineral types.

Hyundai-Kia

Hyundai Motor Group has primarily secured mineral supply through its battery partner Samsung SDI, while also signing direct agreements with Australian lithium producers and Indonesian nickel suppliers. Hyundai has invested in battery recycling ventures and has explored direct investments in African mining assets as part of its long-term supply security strategy.

Deal Structures & Terms

OEM-miner supply deals take several structural forms, each with distinct risk-sharing characteristics and strategic implications:

The trend is toward deeper integration. Early OEM-miner deals were simple fixed-volume offtake agreements. More recent agreements increasingly include equity investment, joint venture development, pre-payment financing, and even direct mine ownership. This deepening reflects the recognition that arm's-length supply agreements may be insufficient to guarantee material access in a market where multiple automakers are competing for the same constrained supply base.

Contract duration has lengthened significantly. While early deals typically covered 3 to 5 years, recent agreements extend to 7 to 10 years or longer, often with renewal options. Some agreements are structured as "life-of-mine" commitments, tying the automaker to a specific mining operation for its entire productive life. This extended duration provides supply security for the automaker but reduces the miner's flexibility to capture higher prices from competing buyers during price spikes.

Africa’s Role in OEM Supply

Africa—particularly the DRC-Zambia Copperbelt—features prominently in OEM mineral procurement strategies. The DRC's dominant position in cobalt supply makes it unavoidable for any automaker using NMC or NCA battery chemistry. Major cobalt supply agreements with Glencore, CMOC, and ERG route directly through DRC mines. Copper supply agreements increasingly include Copperbelt sources as well, with Kamoa-Kakula and Kansanshi production entering OEM supply chains.

The responsible sourcing dimension adds complexity to African mineral procurement. European automakers in particular face regulatory pressure (EU Battery Regulation, German Supply Chain Due Diligence Act) to demonstrate that their mineral supply chains are free from child labour, forced labour, and environmental harm. The DRC's artisanal cobalt sector—which accounts for approximately 15 to 20 percent of the country's cobalt output—has been associated with child labour and unsafe working conditions, creating reputational and legal risk for OEMs sourcing Congolese cobalt.

Several OEMs have responded by restricting their sourcing to large-scale, audited industrial operations and by investing in traceability technologies that can verify the provenance of every kilogram of cobalt in their supply chain. BMW's traceability pilot with CMOC and Glencore's responsible sourcing certification program represent leading examples of this approach. However, critics argue that excluding artisanal miners from formal supply chains marginalises vulnerable communities rather than improving their conditions.

Corridor Implications

The proliferation of OEM-miner supply deals creates a direct commercial linkage between European and American automotive factories and Copperbelt mining operations—and the Lobito Corridor is the logistics infrastructure that connects them. Every tonne of cobalt committed under a BMW-CMOC or Tesla-Glencore agreement must be physically transported from the mine site to the processing facility to the battery factory. The corridor's rail and port capacity determines the speed, cost, and reliability of this material flow.

As OEM supply agreements multiply and volumes increase, the corridor's logistics capacity becomes a binding constraint on supply chain performance. A transport bottleneck at any point along the corridor—rail congestion, port delays, customs processing—ripples through the entire supply chain, potentially causing production disruptions at gigafactories thousands of kilometres away. This interdependence gives both the OEMs and their mining suppliers a commercial interest in the corridor's expansion and efficient operation.

The US DFC and EU investment in the corridor is, in this context, an investment in the reliability of Western automotive supply chains. The geopolitical framing of the corridor as an alternative to Chinese-dominated routes is reinforced by the commercial reality: automakers need a dependable, cost-effective pathway to move Copperbelt minerals to their factories, and the corridor provides it. As the number and scale of OEM-miner supply deals grow, the corridor's commercial value to the global automotive industry grows proportionally.
