A Chinese-led study of Turkey's Kizilcaoren deposit, the country's largest known rare earth reserve, concludes that its mineralisation is small in scale. The lead scientist says it is unlikely to become a major alternative to existing producers soon.
At a glance
- The peer-reviewed study was published in Acta Geologica Sinica on October 9 by Chinese and Turkish researchers.
- An earlier estimate cited in the paper puts Kizilcaoren's ore at about 4.67 million tonnes grading 2.78%.
- China's Bayan Obo deposit holds over 57.4 million tonnes of rare earth-bearing reserves at about 6% grade.
Background
Rare earths are a group of 17 elements used in permanent magnets for electric motors, wind turbines and electronics. China dominates their supply chain, so many countries are looking for deposits of their own. Carbonatites are rare igneous rocks that host major rare earth deposits, including China's Bayan Obo.
What the study found
Chinese researchers have mapped how Turkey's Kizilcaoren rare earth deposit formed, the South China Morning Post reported on October 24. Their peer-reviewed paper appeared online in Acta Geologica Sinica on October 9. Co-authors came from Chinese universities, Istanbul University-Cerrahpaşa and the Xian Centre of the China Geological Survey.
The team traced three stages. Carbonatite magma first intruded the surrounding rock, then hydrothermal fluids rich in rare earths, fluorine and sulphate concentrated the metals. Finally, rainwater altered the rocks and left behind fluorite, barite and rare earth minerals. Lead scientist Professor Yang Xiaoyong called the mineralisation "small in scale".
Why it is unlikely to change supply
An earlier estimate cited in the paper puts Kizilcaoren's ore at about 4.67 million tonnes, at an average grade of 2.78%. That figure is gross ore, not processed rare earth oxides. By comparison, China's Bayan Obo, the world's largest rare earth deposit, holds over 57.4 million tonnes of rare earth-bearing reserves at about 6% grade.
Mining is only the first step. Ore must be processed and separated before it can become magnets. A March report by the US Congressional Research Service estimated China's share at about 60% of global mining, 90% of processing and separation, and 94% of magnet production. Some Kizilcaoren samples also contained more than 1,000 parts per million of thorium, a radioactive element.
What it means
Countries trying to reduce their reliance on China face steep geological and economic hurdles. "A single academic paper cannot change a supply chain," Yang said, adding that the study was academic research, not a project to develop Turkey's resources. According to USGS data cited in the report, China held about 44 million tonnes of rare earth reserves in 2025, followed by Brazil with 21 million and Australia with 6.3 million.
Our read
Outlook: neutral. The study lowers expectations for one possible new source but does not change current rare earth supply or demand.
What to watch
- Any move by Turkey to test Kizilcaoren's commercial potential with drilling or a feasibility study.
- New rare earth projects outside China that add processing and separation capacity, not just mining.
- Further research on carbonatite deposits in the Middle East, where Yang says no substantial deposits have been shown.

Detailed analysis
Timeline
- 2026-10-09: The Kizilcaoren study is published online in Acta Geologica Sinica.
- 2026-10-24: The South China Morning Post reports the findings and interviews lead scientist Yang Xiaoyong.
Supply Drivers
Kizilcaoren's modest ore estimate suggests it will not add major rare earth supply soon.
Geopolitical Risks
China's dominance of processing and magnets keeps pressure on other countries to find their own deposits.
What could lift prices
- The study lowers hopes that Turkey can add a large new rare earth source outside China.
- China's control of about 90% of processing and separation keeps supply concentrated.
What could weigh on prices
- Large reserves outside China, such as Brazil's 21 million tonnes, could still be developed.
- The finding concerns one deposit and does not affect current production.
Country impact
| Country | Impact | Reason |
|---|---|---|
| Turkey | High | Its largest known rare earth reserve looks too small to make it a major producer soon. |
| China | Medium | The study reinforces China's lead in reserves, processing and magnet production. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Critical Minerals Mining | Negative | It lowers expectations for one prospective rare earth source outside China. |
| Electric Vehicle Manufacturing | Neutral | Magnet supply for electric motors stays concentrated in China. |
Who gains, who loses
- Established rare earth producers: Kizilcaoren is unlikely to become a major competitor any time soon.
- Turkey: Its hopes of becoming a major rare earth supplier from Kizilcaoren look limited.
Other ways this could play out
- If further drilling finds higher grades, Kizilcaoren's outlook could improve.
- If processing capacity grows outside China, smaller deposits like Kizilcaoren could become more viable.
Price risks
- New supply from larger deposits outside China could ease rare earth markets.
- Chinese export policy matters far more for rare earth prices than this study.
