Podcast Episode: Why #Greenland? not #Mountainpass, #California for #RareEarth elements?

Pip: Welcome to the podcast where we dig into mining, mineral processing, and metals — sometimes literally. Today we're following the rare earth supply chain from California to the Arctic, courtesy of Nanthakumar Victor Emmanuel, P.Eng.

Mara: That's right — we're looking at why Greenland keeps coming up in rare earth conversations, and what the real obstacles are to building a Western supply chain that actually works.

Pip: Let's start with the Mountain Pass story, and why it matters more than the map suggests.

Why Greenland? The Mountain Pass lesson and what comes next

Mara: The central question here is why Western policymakers keep looking at Greenland when the United States already has a rare earth mine in California — and what that question reveals about the gap between mining and refining.

Pip: The post quotes a researcher named Chrisey to put the technical problem in plain terms: "Two different rare earth elements may be fractions of an angstrom different in diameter — that means it's very difficult to separate using physical means. The processes that are used right now can be 100 steps," with the procedure described as very expensive and environmentally hazardous due to the chemicals used.

Mara: So the upshot is that even if you have the ore in the ground, separating and purifying individual rare earth elements is a genuinely hard chemical problem — not just a permitting or investment problem.

Pip: Mountain Pass is the case study. Molycorp tried to be a one-stop American rare earths solution, and by 2013 revenues were in free fall. The post notes that Molycorp's most profitable assets ended up transferred to Chinese-linked Neo Materials, the mine was purchased out of bankruptcy by a consortium that included a Chinese-owned firm, and Mountain Pass was sending U.S.-mined concentrate to China for processing.

Mara: The dream of domestic end-to-end production collapsed not because the ore ran out, but because the refining technology and economics didn't hold. The post cites Reuters reporting that China controls 87 percent of global rare earths refining capacity, and that Beijing deliberately keeps prices for finished products low to inhibit foreign competition from building their own processing plants.

Pip: It's a neat trap — dig all you want, just send us the concentrate.

Mara: The post lays out a three-step prescription in response: invest in research and development on refining technologies first, build refineries at existing mines with infrastructure before opening new ones, and use tariffs or other tools to take price control away from China while local operations optimize. The reserve numbers matter here too — Greenland has 1.5 million metric tons of rare earth reserves, while the U.S. sits at 1.9 million. Neither country is close to China's 44 million metric tons.

Pip: Which reframes the Greenland question entirely — it's not about the ore, it's about whether Western refining can exist at all before anyone starts a new mine.

Mara: Exactly the argument the post makes. The infrastructure and processing capability have to come before the next frontier dig, or the concentrate just travels east again.

Pip: The economics of refining are where the real supply chain battle is being fought — and that's a thread worth pulling on next.

Mara: The Mountain Pass story keeps repeating because the refining problem keeps being skipped.

Pip: Build the refinery first, then talk about Greenland. That order matters.

Mara: More on the processing side next time.

Podcast Episode: Rare Earths And Trade Tensions

Posted on by Leave a comment

Pip: Welcome to the podcast where we track what the earth gives up and what the markets make of it — rare earths, trade deficits, and the occasional geopolitical scramble.

Mara: Today’s episode, shaped by posts from Nanthakumar Victor Emmanuel, P.Eng, covers three connected territories: Europe pushing back on its trade imbalance with China, a long-term rare earth supply deal out of Greenland, and the magnet problem sitting inside the Pentagon’s drone ambitions.

Pip: Let’s start with the EU-China trade picture.

EU and China: Rebalancing an Unequal Trade

Mara: The European Union is signaling it wants a different kind of relationship with China — one where the trade flows more evenly and the strategic vulnerabilities get addressed.

Pip: The numbers make the case bluntly. The EU’s trade deficit with China reached approximately 360 billion euros last year, and the post notes that “particular concern has centered on rare earth minerals after China imposed export restrictions last year, exposing Europe’s heavy reliance on Chinese supplies.”

Mara: So the upshot is Europe is not just haggling over tariffs — it’s reckoning with structural dependency. A summit in Brussels on June 18 and 19 is expected to advance those discussions, with a possible visit from China’s commerce minister also on the table.

Pip: Which makes Greenland’s rare earth story land with considerably more weight.

The Tanbreez Deal: Greenland’s 15-Year Commitment

Mara: The Tanbreez project in Greenland is one of the world’s largest known heavy rare earth deposits, and it just got a significant commercial anchor.

Pip: Critical Metals has signed a 15-year binding offtake agreement with REalloys, and the post quotes directly: “REalloys will receive priority rights to concentrate containing higher levels of the critical heavy rare earth elements, dysprosium and terbium, along with a right of first refusal over additional volumes.”

Mara: Those two elements — dysprosium and terbium — are exactly the heavy rare earths that go into the high-performance magnets defense and clean energy applications depend on. The deal formalizes and expands a non-binding agreement from last October, and follows Greenland’s April approval for Critical Metals to raise its ownership stake in the project to 92.5%.

Pip: Fifteen years is a long runway. That’s not a spot purchase — that’s a supply chain being built from the ground up.

Mara: Pricing is linked to international rare earth oxide benchmarks, and deliveries ship from the Tanbreez port in southern Greenland. The post frames this in the context of the U.S. and its allies stepping up efforts to secure critical mineral supplies outside China.

Pip: And REalloys turns up in the drone story too — which is where the magnet dependency gets very concrete.

300,000 Drones and the Magnet Bottleneck

Mara: The Pentagon has placed the largest drone order in American history — 30,000 one-way attack drones, with a target of scaling past 300,000 by early 2028. Every one runs on a rare earth magnet.

Pip: And the post puts the constraint in one number: “roughly 98% of the world’s magnets are manufactured in China.” That is a supply chain risk dressed up as an ambition.

Mara: REalloys is positioned as a direct response to that gap — holding what the post describes as the only fully non-Chinese mine-to-magnet heavy rare earth supply chain in North America, from processed metals through to magnet-ready inputs.

Pip: The Greenland offtake deal and this Pentagon supply problem are clearly two ends of the same chain.

Mara: Whether it’s Brussels negotiating with Beijing, Greenland locking in a 15-year deal, or the Pentagon counting magnets — the throughline is the same scramble to diversify critical mineral supply.

Pip: Next time, we’ll see where that scramble leads. The deposits are finite; the demand is not.
