Korea Zinc Bets Big on U.S. Critical Minerals-with Tennessee's "Project Crucible"

Highlights

• Korea Zinc's Project Crucible in Clarksville, Tennessee, targets phased commercial production of critical metals including gallium and germanium beginning in 2029.
• The project received a $210 million CHIPS Act award, reflecting Washington's shift toward funding processing and refining capacity rather than mining alone.
• Project Crucible strengthens U.S. resilience in gallium, germanium, antimony, and indium but does not directly address the rare earth separation bottleneck.
• Korea Zinc's ongoing governance dispute with the Young Poong–MBK Partners alliance poses execution risk that could affect Project Crucible's timeline and capital allocation.
• The project signals that critical minerals competition will be decided by who builds integrated processing ecosystems, not simply who owns mineral deposits.

Korea Zinc (opens in a new tab) is making one of the largest strategic bets yet in the emerging ex-China critical minerals supply chain. In a speech marking the company's 52nd anniversary, Chairman Choi Yoon-beom reaffirmed that the company's US$7.4 billion Project Crucible in Clarksville, Tennessee, (opens in a new tab) will become a global hub for critical minerals processing. The project, supported by a US$210 million CHIPS Act award from the U.S. Department of Commerce, targets phased commercial production beginning in 2029 and will produce a broad portfolio of critical and non-ferrous metals, including gallium and germanium.

The announcement matters because it reflects a larger shift in U.S. industrial policy. Rather than funding mines alone, Washington is increasingly supporting processing and refining capacity—the segment of the supply chain where China maintains its greatest strategic advantage. Korea Zinc's Tennessee project complements other recent U.S.-backed investments in MP Materials, USA Rare Earth, Energy Fuels, and ReElement, reinforcing a broader strategy to rebuild domestic and allied processing capability.

The company's new "Troika Drive" strategy—focused on resource recycling, renewable energy and green hydrogen, and battery materials—also aligns with long-term demand trends for semiconductor and clean-energy supply chains.

Rare Earth Exchanges® sees two important caveats. First, 2029 remains three years away, leaving near-term supply vulnerabilities unresolved. Second, Project Crucible is primarily a critical minerals and multi-metal smelting project, not a rare earth separation facility. It strengthens U.S. industrial resilience in strategically important metals such as gallium, germanium, antimony, and indium, but it does not directly solve the rare earth separation bottleneck that still dominates Western supply-chain risk.

Investors should also monitor Korea Zinc's ongoing governance dispute with the Young Poong–MBK Partners alliance. While management insists the conflict will strengthen the company, legal and shareholder battles could influence execution timelines.

The REEx Bottom Line: Project Crucible is another signal that the future of critical minerals competition will be decided not simply by who owns deposits, but by who builds integrated processing ecosystems. That remains the central battleground in Great Powers Era 2.0.

Did You Know?

Investors should pay close attention to Korea Zinc's unresolved governance battle because execution risk—not simply engineering risk—often determines whether multi-billion-dollar industrial projects are delivered on time and on budget. The company remains locked in a high-profile struggle with the Young Poong–MBK Partners alliance over board control and corporate direction, culminating in an extraordinary shareholders' meeting scheduled for September. While Chairman Choi Yoon-beom argues the dispute has strengthened management discipline and sharpened the company's long-term strategy, prolonged litigation, leadership uncertainty, or shifts in board composition could influence capital allocation, financing priorities, and the pace of Project Crucible's development. For investors, the key question is not whether the Tennessee project remains strategically important—it almost certainly does—but whether corporate governance distractions could slow execution at a time when the United States is racing to build critical mineral processing capacity outside China.

In Great Powers Era 2.0, industrial projects compete not only against technical challenges, but also against the clock. Delays caused by governance instability can become strategic liabilities just as surely as construction delays or cost overruns.
