Concerns over rare earth supply are returning to the global spotlight. Geopolitical tensions have exposed Western dependence on China. Reports indicate some Chinese suppliers stopped shipping rare earth products to US customers.
The reports emerged weeks before Chinese President Xi Jinping’s planned Washington visit. The timing adds pressure as the US-China trade truce approaches expiry.
China supplies around 60% of global rare earth mine production. Its downstream influence is considerably stronger. That imbalance has placed rare earth supply chain security under renewed scrutiny.

Rare Earth Supply Chain Security Enters A New Era
Sprott analyst Justin Tolman describes the shift as a “new era of resource security”. Supply chains are becoming increasingly fragmented across major economies. Rare earth elements clearly demonstrate the strategic consequences of this change.
Their magnetic, optical, and thermal properties are difficult to replicate. Alternative materials can also reduce performance, increase weight, or weaken reliability.
Their importance spans electric vehicles, robotics, wind turbines, and artificial intelligence infrastructure. Advanced automation also depends on these specialised materials. Defence systems add another layer of urgency to the supply equation.
Defence Demand Raises The Stakes
Defence requirements could significantly reshape the rare earth market. Global defence spending exceeds US$2.7 trillion ($3.7 trillion) annually, according to World Bank data. The US Department of Defense requires an estimated 3,000–4,000 tonnes of specialised rare earth magnets annually. That requirement could reach 10,000 tonnes by 2030. The wider global market is roughly 250,000 tonnes. Ex-China magnet production currently stands at only 20,000–25,000 tonnes. The supply gap creates strategic risks for defence manufacturers. Recent F-35 delivery disruptions demonstrated how vulnerable these chains can become.

Why Rare Earth Supply Security Matters To Defence
NATO has deemed REEs one of its 12 defence-critical raw materials. Meanwhile, members have committed to increase defence expenditure to 5% of GDP by 2035. War is becoming sensor-driven, autonomous and electrified.
The move demands that advanced electronics and high-performance components be used. Buyers of defence products will thus be less interested in the price than in reliability of supply. Key considerations include:
- Reliable supply: Buyers must have a reliable supply in geopolitical situations.
- Advanced technology: Permanent magnets power systems such as radars, satellites, and aircraft.
- Strategic resilience: Processing domestically means limiting the risk of exposure to foreign export controls.
China’s Downstream Control Creates A Bigger Challenge
Opening new mines alone will not solve Western supply vulnerabilities. Rare earth supply chains include mining, separation, refining, metals, alloys, and magnet manufacturing.
China has developed major advantages across these stages. The International Energy Agency says China refined 91% of magnet rare earths in 2024. It also produced 94% of finished rare earth magnets that year.
New mines outside China could still depend on Chinese processing facilities. Sprott’s Jacob White says China’s influence reaches AI, data centres, robotics, defence, energy grids, and electric vehicles.
Building An Ex-China Rare Earth Supply Chain
Governments and companies are investing heavily in alternative supply chains. Several US companies are developing mining, processing, and magnet manufacturing capabilities.
MP Materials operates the Mountain Pass Rare Earth Mine and a Texas magnet facility. Energy Fuels and USA Rare Earth are pursuing integrated strategies. The US Department of Defense has also expanded financial support. Key measures include:
- US$1 billion: Pentagon awards since 2020 for domestic rare earth supply chains.
- US$1.55 billion: New critical minerals initiative launched by the DoD.
- US$750 million: Funding aimed at rare earth production and processing capacity in Brazil.
Price support and long-term offtake agreements are also becoming important policy tools.
Canada Emerges As A Potential Rare Earth Source
Canada could become an important contributor to an ex-China rare earth network. The country lacks commercial rare earth production but hosts advanced development projects. Defense Metals is advancing the Wicheeda Project in British Columbia.
Its Prefeasibility Study outlined around 5,000 tonnes of annual NdPr production. That could represent approximately 7–8% of global output. Vital Metals is advancing Prefeasibility work at Nechalacho in the Northwest Territories.
Avalon Advanced Materials owns deeper Nechalacho resources. Its updated resource contains 58.6 million tonnes grading 1.494% total rare earth oxides.
Canada’s Pipeline Adds Further Supply Options
Canada’s rare earth pipeline extends beyond Wicheeda and Nechalacho. Rackla Metals is exploring the South Lened Rare Earths Project.
Its exploration target follows a 3km-long cerium and lanthanum stream-sediment trend. Government survey data also identified significant rare earth anomalies there.
Québec offers another prospective region through Torngat Metals’ Strange Lake Rare Earth Complex. The project targets an open-pit mine and concentration plant towards decade-end.
Makenita Resources also acquired the roughly 3,642-hectare NTX Rare Earth Project last year. Together, these projects strengthen Canada’s potential strategic role.
What The Rare Earth Market Means For Investors
Rare earth supply chain security is becoming a strategic investment theme. However, geological potential does not guarantee commercial success.
Projects face permitting delays, high capital requirements, technical challenges, and volatile prices. Processing infrastructure remains particularly important outside China. Governments may therefore need to support projects through financing and price mechanisms.
The opportunity is strongest for companies developing integrated supply chains. Such businesses could benefit from growing defence demand and policy support.
Yet development timelines remain long. Investors must therefore consider project economics alongside strategic importance and geopolitical value.

Western Supply Chains Could Take Years To Build
China still dominates the rare earth processing and magnet production industry. Capacity development of alternative capacities will thus need to be continuously funded and coordinated.
It’s not just about finding more deposits. Western economies require processing, refining, alloy manufacturing, and magnet production. Such a shift may be hastened by the need for defence.
Public financing could also enhance the viability of the project and lower development risks. Other regions such as Canada, the US, Brazil, etc. may be gaining in significance.
The key questions are how quickly these markets can establish integrated supply chains, and how effectively they can achieve this. The security of resources is now providing rare earth projects with renewed strategic priority.

FAQs
Q1: Why are rare earths important to Western economies?
A1: Rare earths support defence systems, electric vehicles, robotics, AI infrastructure, and advanced electronics. Their specialised properties make substitution difficult without performance compromises.
Q2: How much rare earth mine supply comes from China?
A2: China accounts for around 60% of global rare earth mine supply. Its influence is considerably greater across refining and finished magnet manufacturing.
Q3: Why is mining outside China not enough?
A3: Rare earth supply chains also require separation, refining, alloy production, and magnet manufacturing. Without those capabilities, new mines can remain dependent on Chinese processing.
Q4: Could Canada strengthen Western rare earth supply?
A4: Canada hosts several advanced projects, including Wicheeda, Nechalacho, South Lened, and Strange Lake. These developments could support a broader ex-China supply network over time.
