In short: The "Pentagon bonus." A defense-critical metalloid (~90% of supply in China/Russia/Tajikistan; US imports 85%). China's Dec-2024 export ban pushed it to ~$60k/ton; military-user exports stay banned, the National Defense Stockpile is near-depleted, and the DoD is funding a domestic "ground-to-round" supply chain — the strategic premium underpinning PPTA.
Antimony is an obscure metal that turns out to be essential for weapons, night vision, semiconductors, and grid batteries. Almost all of it comes from China, Russia, and Tajikistan, and the US imports most of what it uses. After China banned exports in late 2024, the price jumped about fivefold. The US military stockpile is nearly empty and the Pentagon is racing to build a home-grown supply — which is exactly why a US antimony source carries a strategic premium and why it makes Perpetua more than just a gold story.
In short: The defense metal at the center of the piece — quadrupled past $60k/ton after China's Dec 2024 export ban; China makes ~60% of supply (90% with Russia + Tajikistan), the US imports 85% and had ~zero domestic output. China's "suspension" is licensing-gated, so access hasn't normalized; the supply crisis "isn't going away."
Antimony is an obscure metal most people have never heard of, but it's essential for ammunition, night-vision gear, sensors and chips. China makes most of the world's supply and banned exports to the US — so the price quadrupled to over $60,000 a ton. The US makes almost none of its own and relied on China for the bulk of imports, so the Pentagon now treats antimony as a national-security emergency. Prins's point: this is a real, under-the-radar supply crisis with the US government actively spending to fix it, which supports prices and the companies that can produce it.
