Korea Zinc Plans $7.4 Billion U.S.-Backed Smelter to Break China's Rare Earth Grip

Korea Zinc is building a massive $7.4 billion smelter with U.S. government backing as Washington pushes to end its reliance on China for critical minerals. The Pentagon will hold a 40% stake in the joint venture funding the project.

If you're trying to figure out how serious the U.S. is about breaking China's stranglehold on critical minerals, here's your answer: the Pentagon is about to become a major stakeholder in a South Korean zinc company.

The Deal Structure

Korea Zinc dropped the news Monday, and it's a big one. The world's largest zinc smelting company is building a $7.4 billion facility with substantial backing from Washington. This isn't just a loan or a handshake deal. The U.S. government is actually taking a piece of the company.

Here's how it works: Korea Zinc will issue $1.9 billion in new shares to a joint venture that's controlled by the U.S. government along with unnamed American strategic investors. That gives the venture roughly a 10% stake in the Korean firm. Within that joint venture structure, the U.S. Department of War holds a 40% interest, while Korea Zinc's ownership sits below 10%.

The remaining $5.5 billion comes from $4.7 billion in loans from the U.S. government and financial institutions, plus $210 million in subsidies courtesy of the Commerce Department under the CHIPS and Science Act. Yes, the same legislation that's been funding semiconductor plants is now backing mineral processing.

Korea Zinc shares jumped 4.87% to KRW 1,592,000 ($1,086.01) on the Kospi Monday, though the plan has sparked pushback from major shareholders who want the chairman out.

Why This Matters Now

The U.S. is almost entirely dependent on foreign suppliers for the processed rare earths that go into high-tech magnets and electronics. China dominates both mining and refining, which security experts have been flagging as a vulnerability for years. The White House is finally doing something about it.

This Korea Zinc project fits into Washington's broader push to reduce reliance on Beijing for critical minerals. The concern intensified after China imposed restrictions on rare earth mineral exports in 2022 and again in 2025. Those moves were wake-up calls.

The U.S. has been working to realign the global rare earth supply chain with its economic and national security priorities. That includes partnerships with companies like MP Materials Corp. (MP) and Saudi Arabian Mining Company. Korea Zinc is now the latest piece in that puzzle.

Whether a $7.4 billion smelter can meaningfully shift the balance of power in critical minerals remains to be seen, but Washington is clearly betting it's worth trying.
