The Antimony Bottleneck: Why Permitting Outpaces Capital in Mining

The supply shock originated in Beijing. Following China’s 2024 export restrictions on antimony and gold-antimony smelting technology, global metal prices surged. With China controlling roughly half of output and the U.S. importing over 85% of its supply, Western policymakers have scrambled to designate the metal as a critical mineral. However, the sector is fractured by divergent strategies to combat the same clock.

Some firms, like Perpetua Resources, are leveraging massive federal loans to navigate the long-term permitting process. Others, such as Americas Gold and Silver, are bypassing the wait by integrating antimony recovery into already-permitted operations. Meanwhile, exploration-stage companies like RUA GOLD are racing to define resources, recently reporting high-grade intercepts at New Zealand's Auld Creek project. While companies like Nova Minerals push toward pilot-scale production, the gap between laboratory results and a commercialized supply chain remains the primary obstacle. Ultimately, the industry is split between those betting on long-term capital deployment and those attempting to shave years off the permitting cycle through existing infrastructure.
