Rare Earth Elements (REEs) power the modern world. These 17 critical metals are essential for electric vehicles, wind turbines, semiconductors, and military applications. While China, the U.S., and Australia dominate current production, vast unexplored or underexplored regions across the globe could reshape the future REE supply chain. Discover the global quest for rare earth element (REE) deposits in unexplored frontiers and emerging hotspots. Learn about new discoveries, mining challenges, and the regions shaping the future supply of these critical minerals.
With the demand for REEs expected to grow by 400% by 2040, countries and corporations are racing to uncover new deposits. But finding REEs is only the first step—turning discoveries into commercially viable mining operations takes years of investment, technology, and geopolitical stability.
Where Could the Next Big REEs Discovery Be?
1. Greenland: A Frozen Treasure Trove
| Location | Estimated REE Potential | Challenges |
|---|---|---|
| Kvanefjeld (Kuannersuit Project) | One of the world’s largest deposits of REEs and uranium | Environmental concerns, political opposition |
| Other Alkaline Intrusions | Heavy REEs-rich carbonatite formations | Harsh climate, permitting hurdles |
🔹 Why It Matters: Greenland’s deposits contain high-value heavy REEs like dysprosium and terbium, crucial for magnets in EVs and wind turbines. If developed, it could reduce Western dependence on China.
2. Eastern and Southern Africa: Untapped Potential
| Country | Key REE Projects | Development Status |
|---|---|---|
| Tanzania | Ngualla Project | Feasibility stage |
| Malawi | Songwe Hill | Early exploration |
| Mozambique, Angola, Madagascar | Various alkaline complexes | Underexplored |
🔹 Why It Matters: Africa has vast REE-rich zones, but systematic exploration remains limited. With investments, the region could emerge as a major supplier.
3. South America: The Next Frontier?
| Country | Known Reserves | Potential Areas |
|---|---|---|
| Brazil | Catalão deposits, significant reserves | Amazon Basin |
| Bolivia, Colombia | Limited exploration | Andes mountain carbonatites |
🔹 Why It Matters: Brazil already has large reserves, and other South American nations could hold untapped REE deposits that require further exploration.
4. North America: Expanding Beyond Mountain Pass
| Region | Potential Reserves | Challenges |
|---|---|---|
| Canada (Quebec, Ontario, Northwest Territories) | Alkaline complexes, Nechalacho deposit | Harsh climate, remote locations |
| United States (Wyoming, Alaska) | Bear Lodge Project, carbonatite formations | Regulatory and permitting hurdles |
🔹 Why It Matters: Canada and the U.S. have stable jurisdictions and advanced mining expertise, but much of their land remains partially explored.
5. Central Asia & Arctic: Emerging Players
| Region | Current Status | Potential |
|---|---|---|
| Kazakhstan | Known uranium leader | REEs in phosphate rocks and uranium tailings |
| Arctic Regions | Increasing accessibility due to climate change | Limited infrastructure |
🔹 Why It Matters: Kazakhstan’s stable economy and resource expertise make it a promising REE supplier, while the Arctic remains a long-term prospect.
6. Seafloor Deposits: The Future of REE Mining?
| Location | Potential Yield | Challenges |
|---|---|---|
| Clarion-Clipperton Zone (Pacific Ocean) | Polymetallic nodules rich in REEs | Costly, environmentally controversial |
| Minamitori Island (Japan EEZ) | Large deep-sea REE deposits | Experimental extraction stage |
🔹 Why It Matters: Deep-sea mining could revolutionize REE supply, but environmental and technological hurdles remain.
7. Newly Announced or Underexplored “Hot Spots”
| Region | Potential | Current Status |
|---|---|---|
| Northern Sweden (Kiruna discovery) | Major REE reserves announced in 2023 | Feasibility studies underway |
| Norway (Fen Complex) | Known REE potential | Slow development due to environmental concerns |
🔹 Why It Matters: Even in developed countries, new large-scale discoveries are still happening, proving that more deposits await exploration.
Challenges in Unlocking These REEs Deposits
While the world is eager to reduce reliance on China for REEs, the path to developing new supply chains is complex:
- Political/Regulatory Issues: Permitting, environmental concerns, and government policies often delay or block projects.
- Technical Complexity: REEs are not easy to process, requiring advanced separation technologies.
- Market Uncertainty: Prices can be volatile, affecting investment decisions.
- Long Development Timelines: From discovery to production can take 10–15 years.
Despite these hurdles, the demand for REEs is too high to ignore, and more nations will invest in exploration in the coming decade.
Conclusion: Insights from Mattias Knutsson
Rare Earth Elements are not just minerals; they are the foundation of the next technological revolution. Securing their supply is crucial for economic stability, national security, and the green energy transition.
According to Mattias Knutsson, a global procurement and business development expert, “The race for rare earth elements is intensifying. Nations that develop self-sufficient supply chains will gain a significant geopolitical and economic edge. Investment in sustainable mining and advanced recycling will define the leaders of the future.”
As more regions explore their REE potential, the monopoly China currently holds may face real competition in the coming years.
What’s Next in the REE Series?
As we explore the future of rare earth elements, another major question arises: Is mining the only way forward? What if we could extract valuable REEs without digging into the Earth at all?
