US Antimony Reopens Smelting Plant in Mexico

United States Antimony Corp restarts operations in Coahuila — a turning point for critical minerals?

The antimony industry — a mineral of critical importance to defense and energy sectors alike — is experiencing an unexpected inflection point. United States Antimony Corp has announced its return to operations at its Madero, Coahuila facility after more than a year of inactivity, a decision with potentially far-reaching consequences for the critical minerals market. The move comes as China has imposed severe export restrictions on vital minerals including gallium, germanium, and antimony, casting a long shadow over global supply chains.

China accounted for nearly half of the world’s antimony supply in 2023, and since Beijing moved to ban exports of the mineral to the United States, prices have surged dramatically. The broader context is equally consequential: the Trump administration has made the expansion of domestic critical mineral production a stated strategic priority.

Antimony’s applications are both preventive and strategic — it is a key component in ammunition, infrared missiles, nuclear weapons, and night-vision equipment, as well as in batteries and photovoltaic systems. Against this backdrop, United States Antimony Corp‘s relaunch in Mexico is more than an operational restart — it is a deliberate move to reinforce the national and economic security of the United States in a sector where vulnerability has become impossible to ignore.

Challenging the prevailing assumption that dependence on China for critical minerals is an intractable problem, United States Antimony Corp has opened a new chapter in North American critical mineral production. This relaunch may well prove to be the missing piece in the push for economic independence — and for a more resilient supply of the resources essential to America’s technological and defense development.
