Beijing Wants a Piece of America's Rare Earth Mine. The Pentagon Already Owns One.

Summer of 2005. A Chinese oil company called CNOOC bid $18.5 billion for Unocal, a mid-size American energy firm. Congress erupted. The House passed a resolution to block the deal. CNOOC pulled its offer in August. Chevron swooped in and bought Unocal instead. The lesson was simple: Beijing cannot buy strategic American assets without a fight.

Twenty-one years later, Beijing is trying again. This time it's not oil. It's rare earths.

Reuters reported on September 18 that China Rare Earth Group is in talks to buy Shenghe Resources. China Rare Earth Group is state-owned, formed in 2021 by merging several of Beijing's biggest rare earth producers into one company. Shenghe is a Shanghai-listed mining and trading firm. It also owns about 3% of MP Materials, the company that runs Mountain Pass in California. That's the only active rare earth mine in the United States.

Here is why the deal matters. The Pentagon is MP Materials' largest shareholder. The Defense Department bought $400 million in preferred stock and warrants last year to help MP build a mine-to-magnet supply chain on American soil. If China Rare Earth Group buys Shenghe, Beijing would hold an indirect stake in the same company the U.S. military is backing.

Think about that for a second. The Pentagon and Beijing, sitting on the same cap table. A 3% stake doesn't give China a board seat or veto power. But it puts a state-owned Chinese rare earth company inside the ownership structure of America's most important rare earth mine. In 2005, Congress stopped CNOOC from buying an oil company. This deal is smaller and more indirect. Whether it draws the same kind of attention depends on what happens in the next forty-nine days.

The timing makes it sharper. Xi Jinping meets Donald Trump at the White House in two days. The Busan truce — the deal struck last November that froze both sides' export controls — expires on November 10. Both sides want to extend it. But as the World Economic Forum reported this week, they disagree on how long. Beijing wants the freeze to last through the end of the Trump term. Washington wants a shorter leash.

That's the surface talk. Underneath it, both countries are locking in position. The Pentagon bought into MP Materials. Beijing is buying into Shenghe to get a seat at the same table. One country still refines about 90% of the world's rare earths. Every move counts — especially two days before a summit and forty-nine days before a truce expires.

I believe Elon is about to make his latest invention available to the public.

When he does, sales could go through the roof.

And the stock price of one of his critical partners could soar.

I expect Elon to make this announcement any day now. By the end of the month at the latest.

But you never know with Elon…

He could post it on X tomorrow.

So, there's very little time to act.

SUMMIT

Both Sides Want the Busan Truce Extended. They Can't Agree on How Long.

Analysts across CSIS, the World Economic Forum, and ChinaFile all reached the same conclusion this week: the Busan truce will probably be extended at Thursday's summit. The truce, struck on November 10, 2025, suspended both Washington's Affiliates Rule and China's October 9 rare earth export controls for one year. Scott Kennedy at CSIS told WEF that Beijing wants the freeze to last through the end of the Trump administration. Washington reportedly prefers a shorter renewal. If the truce lapses on November 10, the full export-control package — covering rare earth processing equipment, technology, and separated heavy rare earth oxides — snaps back into force.

Geomega's Rare Earth Recycling Plant Nears Commissioning in Quebec

Geomega Resources (TSXV: GMA) said its rare earth magnet recycling demo plant in Saint-Hubert, Quebec, is almost finished and should start commissioning in November. The company got an environmental permit in June that allows operations through 2028. The plant is designed to prove that Geomega's chemical process works at larger than lab scale. Unlike the acid-heavy methods common in China, Geomega's approach avoids harsh solvents. Geomega is also talking to potential feed suppliers and toll-processing partners. If the plant works, it becomes one of the first recycling-to-oxide operations in North America.

DOE Asks Industry: What Would You Do With Surplus Critical Minerals at Old Weapons Sites?

The Department of Energy's cleanup office released an expression of interest on September 18. It's asking American companies what they would do with surplus critical minerals sitting at old DOE sites. The list includes aluminum, copper, lead, platinum, silver, tungsten, vanadium, lithium hydride, and others. Sites like Paducah in Kentucky have been piling up these materials for decades. The EOI is not a sale — it's a test of whether private industry can find a use for what the government already has. If it works, it's a new domestic source that requires zero mining.

Everyone is talking about Trump's new tech law.

Financial Times says this tech puts America "on the verge of a financial revolution."

Yahoo Finance says it could unlock $400 trillion.

Jeff Brown was consulted by Congressional offices in Washington, D.C. to advise on it.

He says the real number is even bigger — as much as $2.6 quadrillion could pour onto a new type of investment exchange in the days ahead…

 
"The Chinese have wanted an agreement to extend the trade ceasefire through the end of the Trump administration."

Scandium
The Element

Scandium is the lightest rare earth and one of the hardest to find. Mix a tiny amount into aluminum and the alloy gets stronger, lighter, and more heat-resistant — which is why the aerospace and defense industries want it. Russia, China, and the Philippines produce almost all of it. There is no large-scale Western scandium mine in operation.

Scandium metal trades at $3,087.59 per kilogram on the SMM benchmark as of September 3, down 7.36% from August. That drop came as demand from China's aluminum sector slowed. For a metal with no substitute in its best applications, any supply disruption would hit fast.

Scandium metal fell to $3,087.59/kg in September, down 7.36% from August. Weaker demand from aluminum-scandium alloy makers in China drove the decline.
