The Antimony Squeeze: Strategic Players in the Spotlight

Geopolitical tensions spark a critical mineral crisis, pushing companies to secure antimony supplies and reshape global markets.

Editorial Team (ET)May 11, 2026

The U.S.-China trade tensions have escalated dramatically with Beijing’s decision to ban exports of critical minerals like gallium, germanium, and antimony to the United States. These materials, indispensable for defense and technology industries, are now being weaponized in a high-stakes geopolitical chess game.

Antimony, a lesser-known but vital mineral, is at the center of this conflict. Essential for military hardware and advanced technologies, its supply chain disruption highlights the vulnerability of U.S. industries dependent on Chinese exports. This article examines key players stepping up to address this critical mineral crisis and explores investment opportunities in this evolving landscape.

What is Antimony and Why Does It Matter?

Antimony is crucial in defense, technology, and energy sectors. It’s used in: Ammunition and missile systems for its hardening properties. Batteries and flame retardants critical for energy storage and safety. Advanced alloys for enhanced durability in military and industrial applications.

From its role in World War II ammunition to today’s cutting-edge technologies, antimony has remained a cornerstone of strategic industries. Its utility in strengthening lead for bullets and producing tungsten steel underscores its enduring importance.

China’s Dominance and the Antimony Supply Chain Crisis

China controls nearly 50% of global antimony mining and 80% of its production. With the December 3, 2024 export ban, supply chain vulnerabilities have been laid bare.

Antimony prices have surged over 200% in 2024 alone.
U.S. defense contractors face mounting pressure to secure alternative sources.

The reliance on Chinese antimony poses national security risks, particularly for defense companies like Lockheed Martin (NYSE: LMT), which require stable supplies for missile systems and fighter jets.

Military Metals Corp. (OTCQB: MILIF, CSE: MILI)

Emerging Leader in Critical Minerals

Based in British Columbia, Military Metals Corp. is capitalizing on the antimony crisis by acquiring mineral-rich properties across Europe and North America. The company’s focus on stable jurisdictions positions it as a reliable alternative to Chinese suppliers.
