Rare Earth Data & Statistics
Investment decisions in rare earth elements require quantitative analysis of production capacity, reserve life, trade dependencies, and supply concentration. This section provides data frameworks to evaluate supply security, identify bottlenecks, and assess geopolitical risk vectors.
Key Data Categories
Production Data
Annual rare earth mine production by country, measured in rare earth oxide (REO) tonnes. China mined about 69% of the world total in 2025, according to USGS. Production concentration creates supply risk and pricing leverage.
- Mine production by country (USGS)
- Each country's share of world output
- Mining vs processing concentration
Reserves & Resources
Total rare earth reserves represent economically recoverable REO under current prices and technology. Resources include additional deposits not yet viable. Reserves do not equal production capacity.
- Reserves by country (USGS)
- Reserves vs resources (JORC, NI 43-101)
- Why large reserves do not mean abundant supply
Trade Flows
REE trade data reveals dependencies. Many countries import ore, concentrate, or separated oxides from China for downstream processing. Export controls can disrupt these flows instantly.

Critical Data Insights for Investors
1. Concentration Risk
China accounts for around 90% of rare earth refining, according to the IEA. Much ore mined outside China has been shipped there for separation, although the US and Australia are building their own processing. This processing bottleneck is the key investment constraint.
2. LREE vs HREE Supply
Light rare earth production (La, Ce, Nd, Pr) exceeds demand in some categories. Heavy rare earth supply (Dy, Tb, Y) is concentrated in southern China and Myanmar and is subject to Chinese export licensing. Investors should distinguish between LREE and HREE exposure in mining portfolios.
3. Demand Growth Drivers
EV and wind capacity build-out drives magnet REE demand (Nd, Pr, Dy, Tb). LED and display demand for phosphor REEs has plateaued. Catalyst demand for La and Ce remains steady. Match company production mix to demand growth vectors.
Using Data for Due Diligence
When evaluating REE investments, cross-reference:
- Company Reserve Claims: Compare to third-party geological reports. Check LREE vs HREE mix in resource base.
- Production Guidance: Verify against country-level production data. Many "rare earth stocks" have minimal actual REE revenue.
- Processing Capacity: Does the company own separation assets or rely on toll processing in China? Trade flow data reveals these dependencies.
- Off-Take Agreements: Match customer locations to trade flow data. Are customers in jurisdictions vulnerable to export controls?
- Supply Security: Countries with domestic mines but no separation capacity remain import-dependent. Full supply chain integration matters.
