HONG KONG — One of the world’s last processors of rare earth metals outside of China is buying mining rights in Greenland to reduce dependence on Russian ore and stabilize prices, in the latest move by Western companies to diversify supply chains following Russia’s invasion of Ukraine.
Rare earth metals are essential for the manufacture of a broad range of modern products, including electric car motors, offshore wind turbines and smart bombs. Demand has soared as automakers switch more of their production to electric vehicles.
Dozens of mostly small companies mine rare earth ore around the world and do some initial processing to remove dirt. But only two commercial-scale factories outside of China perform the difficult task of chemically separating semi-processed ore into usable material for magnets in electric car motors and other applications.
Toronto-based Neo Performance Materials buys semi-processed ore from Russia, the United States and Australia and does the chemical processes at factories in Estonia and China. Another company, Lynas Corporation, mines rare earth metals ore in Australia and does the chemical processes in Malaysia.
Neo said on Monday that it is acquiring rare earth mining rights in Greenland from Hudson Resources, a tiny mining company based in Vancouver. The acquisition marks the first move into rare earth mining by Neo, whose Magnequench division is the corporate descendant of a former General Motors subsidiary that pioneered many modern magnetic applications of rare earth metals in the 1980s.
G.M. saw little potential then in electric cars and disposed of the operation in 1996.
Constantine Karayannopoulos, the chief executive of Neo, said that his company planned to start mining and processing ore in Greenland in two to three years, with full production in about five years. The semi-processed ore will be shipped to Neo’s chemical separation factory in Estonia, a former Soviet republic on the Baltic Sea in Eastern Europe.
Neo’s goal is to free itself of the need to buy ore at world prices. These prices fluctuate more widely than most commodities, surging up to 10-fold during periods of geopolitical tensions before crashing once tensions ease.
“I want the flexibility to feed 100 percent of my own production, or 50 percent my own and buying in the market,” Mr. Karayannopoulos said in a telephone interview. Having a reliable, in-house source of raw material will make it possible to sell rare earths at fixed prices on long-term contracts with automakers, making the deployment of electric cars easier and more financially predictable, he added.
Neo is also preparing to start building this winter a factory in Estonia that will turn processed rare earths into magnets for electric car motors. With European automakers shifting production quickly toward electric cars, the European Union is offering financial assistance for the creation of a mines-to-magnets supply chain within Europe for rare earths.
Although Greenland is geographically part of North America, it is an autonomous district of Denmark, a member of the European Union.

- Inflation Reduction Act: The law extends tax incentives in an effort to steer more U.S. consumers toward electric cars. But new rules complicate the qualification process.
- Plug-In Hybrids: After falling behind all-electric cars, U.S. sales of plug-in hybrids have been surging. The high cost of electric cars and gasoline have given them an opening.
- Car Crashes: Tesla and other automakers capture data from their vehicles to operate their products. Experts say the collected information could also improve road safety.
- A Frustrating Hassle: The electric vehicle revolution is nearly here, but its arrival is being slowed by a fundamental problem: The chargers where people refuel these cars are often broken.
The factory in Estonia currently buys three-fifths of its rare earth ore from Russia and the rest from Utah. The West has imposed many sanctions and other restrictions on companies and exports from Russia, but not yet on rare earth metals.
Neo is not the first company to try to mine rare earths in Greenland. A consortium including a Chinese state-owned enterprise tried to open a mine at the southern tip of Greenland several years ago, at a rare earths deposit that also holds considerable uranium. That project was blocked by local opponents and regulators worried about the risk of radioactive contamination of the environment.
Don Hains, a Canadian geologist who has advised Hudson Resources in Greenland and will now become a consultant to Neo, said that the deposit in Sarfartoq being acquired by Neo has 97 percent less radioactive material per ton than the deposit at the southern tip of Greenland.
Radiation levels at Sarfartoq are “less than what you would find sitting on granite boulders beside the ocean in Maine,” he said.
The Sarfartoq deposit, on Greenland’s western coast, is also considerably smaller than the one at the southern tip of Greenland. But Mr. Karayannopoulos said that the Sarfartoq deposit still had enough rare earths to meet Neo’s entire worldwide processing needs for at least 30 years, and possibly for a century if further drilling at the edge of the deposit confirms further rare earth ore.
Mr. Hains said that ocean currents along the west coast of Greenland keep it free of ice through the winter, making it easier to ship semi-processed ore to Estonia.
Rare earths, a group of 17 elements near the bottom of the periodic table, are not radioactive, but radioactive contaminants like uranium and thorium occur naturally in rare earth deposits. Controversies over how to dispose of those contaminants have led to the shuttering of rare earth separation factories over the past 40 years in Japan, Australia, France and the United States.
That has left China as the world’s main miner and separator of rare earths. Russia is the fourth-largest miner of rare earth metals.
The United States and Australia are roughly tied for a distant second in mining. Almost all of the American ore is mined in California and goes to China for processing, although a little is produced in Florida and processed in Utah. President Biden and Governor Gavin Newsom of California announced plans in February to subsidize the restarting of chemical separation in California.
Rare earth metals have been a highly visible industry ever since China halted exports to Japan for two months in late 2010 during a territorial dispute.
Rare earths are essential but mostly used in trace amounts, so the actual value of the industry is small. Industry analysts put the worldwide value of rare earth ore sales at about $2 billion, and the value of completely processed magnetic powders and other rare earth materials at nearly $8 billion.
Neo said that it would make an initial payment of just $250,000 to Hudson for the mining rights, followed by $3.25 million once the Greenland government approves the transaction. Mr. Karayannopoulos said that he had discussed the plan with officials in Greenland before making the deal, and was optimistic that it would not be blocked like the separate, Chinese-backed project.
Neo is setting up a new subsidiary to make the purchase, and also agreed that Hudson would have the right to 5 percent of the proceeds from a sale or initial public offering of the subsidiary within five years.
Carmakers in the United States are only starting to make the same demands as European carmakers for a mines-to-magnets supply of rare earths near their assembly plants. G.M. said last October that it would discuss rare earth supply chains in the United States with General Electric.
Mr. Karayannopoulos predicted that the American auto market would evolve in the same direction as Europe’s.
“Once we prove this out in Europe, I want to do the same thing in North America,” he said.
