North America holds significant critical minerals deposits across lithium, nickel, cobalt, copper, and rare earth elements, and is deploying substantial government capital to convert geological endowment into active supply chain capacity. The US and Canada together represent the most strategically important Western-aligned critical minerals jurisdiction outside Australia, with combined government commitments exceeding $20 billion in mining and processing incentives since 2022 through the IRA, the Canadian Critical Minerals Strategy, and bilateral MSP frameworks. Critical minerals North America supply remains sub-scale relative to demand — the US imports over 50% of its requirements for 31 of 50 designated critical minerals — but the project pipeline is expanding rapidly.
Critical Minerals Overview — North America
The US Geological Survey identifies over 500 active or advanced-stage critical mineral projects across the US and Canada as of 2025. Lithium projects in Nevada, North Carolina, and Quebec are the most advanced in the battery materials category. Rare earth production is concentrated at MP Materials’ (NYSE: MP) Mountain Pass facility in California — the only operating rare earth mine and partial processing facility in the US. Canada’s nickel and cobalt production, led by Vale (NYSE: VALE) and Glencore (LSE: GLEN) operations in Sudbury and Cobalt, Ontario, supplies a portion of North American battery supply chain demand, though significant volumes still flow to Chinese processors.
The Inflation Reduction Act’s critical minerals provisions have redirected investment into qualifying Free Trade Agreement (FTA) partner supply chains. Canada’s designation as a domestic source equivalent for IRA purposes has made it the largest single beneficiary of US battery supply chain investment outside the US itself, with projects in Ontario, Quebec, and British Columbia attracting multi-billion-dollar commitments from automotive OEMs and battery manufacturers.
Key Minerals by Country — North America
| Country | Key Minerals | Notable Projects | Status |
|---|---|---|---|
| USA | Lithium, REE, Copper, Nickel | Mountain Pass (REE), Thacker Pass (Li), Piedmont Lithium | Production / Development |
| Canada | Nickel, Cobalt, Lithium, REE | Sudbury Basin (Ni/Co), Québec Li projects, Frontier Lithium | Production / Development |
| Mexico | Lithium, Copper, Silver | Sonora Lithium (Bacanora/Ganfeng) | Development — regulatory uncertainty |
The Thacker Pass lithium project in Nevada, operated by Lithium Americas (NYSE: LAC), is the largest advanced-stage lithium development in North America. Backed by a $2.26 billion conditional loan from the US Department of Energy, Phase 1 targets 40,000 tonnes per annum of battery-grade lithium carbonate equivalent. First production is targeted for 2027, subject to construction progress. In Canada, the James Bay region of Quebec has emerged as a significant lithium corridor, with several spodumene projects at feasibility and pre-construction stage.
Major Companies & Projects — North America
MP Materials (NYSE: MP) operates Mountain Pass, California — the sole US rare earth mining and partial processing facility, producing approximately 45,000 tonnes of rare earth oxide concentrate annually. The company is constructing a rare earth metal and alloy facility in Fort Worth, Texas, with US DoD backing, targeting NdFeB magnet alloy production by 2025–26. Lithium Americas (NYSE: LAC) holds Thacker Pass. Piedmont Lithium (NASDAQ: PLL) is developing a spodumene project in North Carolina and holds a cornerstone offtake with Tesla. Compass Minerals (NYSE: CMP) is advancing a lithium brine asset in Utah. In Canada, Frontier Lithium (TSXV: FL) and Patriot Battery Metals (TSX: PMET) are among the most advanced junior developers.
Defence procurement is an increasingly significant demand driver for North American critical minerals. The US DoD’s Strategic Materials programme has awarded contracts for domestic REE, cobalt, and tungsten production, with further rounds of funding expected through 2026 under the National Defense Authorization Act.
Policy, Regulation & Investment Climate
The US IRA (2022) and its battery content rules, the CHIPS and Science Act, and the National Critical Capabilities Defense Act collectively form the most significant industrial policy framework for critical minerals in US history. Canada’s Critical Minerals Strategy (2022) committed C$3.8 billion over eight years to exploration, infrastructure, processing, and recycling. Both governments have streamlined permitting for critical mineral projects — the US through the FAST-41 process and Canada through the Impact Assessment Act amendments — though timelines remain measured in years rather than months for large projects. Mexico’s 2022 nationalisation of its lithium resources under Litio para México (LitioMx) has created regulatory uncertainty that has slowed foreign investment into what is potentially a significant lithium resource.
North America in the Global Critical Minerals Supply Chain
The North American critical minerals sector is explicitly positioned as a strategic alternative to Chinese supply, backed by government-to-government agreements under the MSP, the US-EU Trade and Technology Council, and bilateral deals with Australia, Japan, and South Korea. Processing capacity remains the critical gap — the region has sufficient geological resource but lacks the refining and chemicals capacity to convert ore into battery-grade materials at scale. Several lithium hydroxide and cobalt sulphate processing facilities are under construction or in permitting in the US and Canada, with first production timelines in the 2026–2028 range.

What critical minerals does North America produce?
North America produces rare earth elements (Mountain Pass, California), nickel and cobalt (Sudbury Basin, Ontario), lithium (brine and spodumene projects in Nevada, Quebec, and North Carolina), copper (Arizona, British Columbia), and smaller volumes of tungsten, vanadium, and phosphate. The US and Canada together are advancing the largest pipeline of new critical mineral projects outside China and Australia, though most remain in development or construction phase as of 2026.
Which companies are leading critical minerals production in North America?
Key producers include MP Materials (NYSE: MP) for rare earths, Vale and Glencore for nickel and cobalt in Canada, and a pipeline of advanced developers including Lithium Americas (NYSE: LAC), Piedmont Lithium (NASDAQ: PLL), and Frontier Lithium (TSXV: FL). Major mining companies BHP, Rio Tinto, and Glencore all have significant North American assets or development commitments.
How is the US government supporting critical minerals production?
The Inflation Reduction Act provides tax credits and domestic content incentives for battery materials sourced from the US or FTA partners. The US Department of Energy has issued multi-billion-dollar conditional loans to advanced projects including Thacker Pass. The Department of Defense funds domestic production of defence-critical minerals under the Strategic Materials programme. The FAST-41 permitting process has reduced review timelines for qualifying projects.
What is the biggest challenge for critical minerals in North America?
Processing capacity is the most acute bottleneck. North America has substantial mineral deposits but lacks the refining and chemical processing facilities to convert ore into battery-grade lithium hydroxide, cobalt sulphate, and rare earth alloys at commercial scale. Building this midstream capacity requires capital-intensive facilities, specialist expertise, and construction timelines of 3–5 years. Environmental permitting adds further lead time, particularly for projects on federal land in the US.
How does Canada fit into the US critical minerals strategy?
Canada has been designated as a domestic source equivalent for the purposes of the US Inflation Reduction Act, meaning Canadian-sourced critical minerals qualify for IRA battery content credits. This has made Canada the primary beneficiary of US-allied critical mineral investment, with Ontario and Quebec emerging as key locations for new lithium, nickel, and cobalt projects. The two governments operate a joint Critical Minerals Action Plan and participate jointly in the Minerals Security Partnership.
What is the outlook for North America critical minerals in 2026?
Several advanced projects are expected to reach construction milestones or first production in 2026–2027, including Thacker Pass Phase 1 and multiple Canadian lithium developments. Processing facility construction — particularly for lithium hydroxide — is progressing in the US Southeast and Ontario. Analysts at Wood Mackenzie and Benchmark Mineral Intelligence expect North America’s share of global lithium chemical production to rise from under 5% currently to 10–15% by 2030, subject to project execution.
