SNIP: In the tenth century, Erik the Red, a Viking from Iceland, was so impressed with the vegetation on another Arctic island he had found he called it “the green land.” Today, it’s Greenland’s rocks that are attracting outsiders – superpowers riding a green revolution.

The world’s biggest island has huge resources of metals known as ‘rare earths,’ used to create compact, super-strong magnets which help power equipment such as wind turbines, electric vehicles, combat aircraft and weapons systems.

The metals are abundant globally, but processing them is difficult and dirty – so much so that the United States, which used to dominate production, surrendered that position to China about 20 years ago.

As Greenland’s ice sheet and glaciers recede, two Australia-based mining companies – one seeking funding in the United States, the other part-owned by a Chinese state-backed firm – are racing for approval to dig into what the U.S. Geological Survey (USGS) calls the world’s biggest undeveloped deposits of rare earth metals.

The contest underscores the polluting side of clean energy, as well as how hard it is for the West to break free of China in production of a vital resource. Rare earth metals have many uses, and last year China produced about 90% of them, according to Toronto-based consultancy Adamas Intelligence. As U.S.-China tensions mount, President Joe Biden’s administration said last month it will review key U.S. supplies, including rare earths, to ensure other countries cannot weaponise them against the United States.

Each Greenland mine would cost about $500 million to develop, the companies say. Both plan to send mined material away for final processing, an activity that is heavily concentrated in China. The only rare earth mine now operating in the United States – Mountain Pass in California – is partly owned by a Chinese state-backed company that currently sends material mined in the U.S. to China for processing.

The Greenland sites are less than 16 km (10 miles) from each other at the southern tip of the island, near a UNESCO World Heritage Site. Debate on them has triggered a political crisis in the capital of Nuuk, forcing a general election on the island of 56,000, due in April. Many Greenlanders, while concerned about pollution, feel mining is key to develop their fragile economy. In a 2013 poll, just over half said they want raw materials to become the country’s main source of income.

The country may ultimately back either project, both, or neither, but for those Greenlanders open to mining, the two proposals boil down to a choice between one mine that would not produce radioactive material, and another that would.

The first mine, a private initiative from an Australian geologist who has presented it to U.S. officials, would not involve nuclear material. It has won preliminary environmental approval, but it needs cash and a processing plan.

The second one has already spent more than $100 million preparing to mine, has proven processing technology through its Chinese partner, and won initial political support from Greenland’s coalition government. But its plans include exporting uranium, a nuclear fuel, and it recently ran into strong opposition, including from residents of the nearby town of Narsaq.

“As indigenous people we have lived in harmony with nature for many, many years,” said Mariane Paviasen, an opposition lawmaker who lives in the town. “We use these lands to hunt and fish.”

Greenland’s rare earth metals are also a chance for America and Europe to regain control of a strategic resource.

The island’s potential as a source of the raw materials needed for renewable energy technologies gained momentum in 2010, when China threatened to cut off its supply of rare earth metals to Japan, and tightened quotas to international buyers.

Prices for some of the metals have jumped in recent months, driven by surging demand for electric vehicles as well as concerns that Beijing may restrict sales.

Greenland’s position near the eastern flank of the United States makes it a sensitive location. Former U.S. President Donald Trump offered to buy the island in 2019, and he was not the first U.S. president to do so: In 1946 Harry S. Truman offered Denmark $100 million for it. A defence treaty between Denmark and the United States dating back to 1951 gives the U.S. military almost unlimited rights there, and Greenland houses the northernmost U.S. military base.

The only major plant outside China that does the complex work of separating individual rare earth elements is in Malaysia. But others – including the Mountain Pass mine in the United States – are planning or have started to build such facilities.

“For the foreseeable future, China is going to be the major player in all of these supply chains simply because it’s so far advanced and because it’s not stopping and waiting for alternatives to catch up,” said Ryan Castilloux, head of Adamas.

Tanbreez says half the rare earth metals it mines would be lanthanum and cerium – relatively plentiful metals used in telescope lenses and auto catalysts to cut emissions. About a fifth would be yttrium, which is in demand for lasers and the superconductors used in quantum computing.

Neither of the Greenland projects would be pollution-free. Both plan for mined rock to be locally crushed and separated into concentrates to send for final processing.

Tanbreez’s mining waste will be piped to a lake which, while it does not contain fish, feeds a river with a large population of Arctic char. Turbid water could impact the char, according to the company’s environmental report, which says it plans to dump some 550 tonnes a day of waste material into the lake and will dam it to prevent disruption downstream.

Tanbreez’s plan has passed the public consultations stage and received a government permit in September. Now the company is working on parliament approval.

The rival mountaintop site not far from Tanbreez is called Kvanefjeld, or Kuannersuit in Greenlandic. For John Mair, managing director of its owner, Greenland Minerals Ltd, it’s a world-class opportunity at the right moment.

Kvanefjeld’s main offer is neodymium, needed for wind turbines. Brussels says the EU’s demand for the metal may reach 13,000 tonnes per year by 2050, three times more than it used in 2015. Neodymium is also used in combat aircraft.

Greenland Minerals, which bought its concession from Barnes, says its planned mine will, at least initially, send minerals it produces to China for final processing. It says it plans to find a site in Europe, but has not said when.

But Greenland Minerals faces public opposition. It is one step behind Tanbreez in the environmental vetting process – and its ores include significant amounts of radioactive materials.

When Greenland Minerals embarked on public consultations this year, protests erupted. At one meeting in Narsaq on Feb. 10, locals both inside and outside the hall banged windows and played loud music to disrupt presentations.

As opposition mounted, a small pro-mining party, Demokraatit, triggered a general election by pulling out of Greenland’s coalition in early February.

Polls suggest Greenland’s main opposition party, Inuit Ataqatigiit (IA), which has a zero-tolerance policy for uranium, will become the biggest in parliament, so would be first to try to form a new coalition.

“Our aim,” IA lawmaker and Narsaq resident Paviasen told Reuters, “is to halt the (Kvanefjeld) mining project.” But IA says it has not expressed opposition to Tanbreez, which is seen as less of a threat to the environment.

Kvanefjeld would dump much more waste than Tanbreez – about 8,500 tonnes each day – into a lake on top of the mountain, the Greenland Minerals plan says.

Greenland Minerals says any increase in background radiation from its Kvanefjeld mine will be minimal. It plans to build a concrete 45-meter dam to contain the radioactive waste and to spray water on the ground to keep the dust from blowing away.

The dam will be built to international standards to “withstand even the worst imaginable seismic activity,” it said in a report submitted to Greenland’s government last year.

Even so, residents say they worry contaminated water will seep into nearby rivers or that the dam will fail entirely. They cite the collapse of a mining dam in Brazil two years ago that killed 270 people.

As the crisis has deepened, Greenland Minerals’ shares have dropped by more than 50%. If the mine goes ahead, Paviasen says, many people plan to move away.
