Key Players
Competitive Landscape
Compounders and battery makers pick antimony suppliers on oxide purity, dust control and the certainty of each shipment's origin. China mined an estimated 40,000 tons in 2025, Russia 32,000 tons and Tajikistan 22,000 tons, US Geological Survey data show.[1] Western smelters therefore compete on secure origin and government contracts, and Chinese converters compete on price.
Since mid-2025, Western companies have moved from exploration to production. Perpetua began construction in Idaho in October 2025.[6] The Montana smelter USAC shipped first DLA ingots in the second quarter of 2026.[4] Larvotto produced first concentrate at Hillgrove in September 2026.[7] Korea Zinc set a goal of above 240 tons of US antimony supply in 2026.[3]
Company developments mapped to drivers, trends and opportunities (2026-2036)
| Development | Driver | Trend | Opportunity |
|---|---|---|---|
| July 2026: USAC delivered first DLA antimony ingots. | Defence stockpile rebuilding. | Domestic smelting grows in Montana. | Government orders give smelters a base load. |
| September 2026: Larvotto produced first Hillgrove concentrate. | Western demand for a second source. | Australian by-product supply expands. | Offtake partners gain non-Chinese feed. |
| October 2025: Perpetua broke ground on the Stibnite project. | Federal funding for critical minerals. | US primary mine supply returns. | Converters can sign domestic offtake. |
| September 2026: Korea Zinc set a goal of above 240 tons of US antimony supply. | US import reliance near 90%. | Asian smelters serve US buyers. | Korean oxide and metal reach US compounders. |

Miners sell concentrate to smelters, and smelters sell metal to oxide converters and defence agencies. USAC runs operations in Montana and Mexico.[4] Mandalay sells Costerfield concentrate as a by-product of gold mining.[8]
Who leads the antimony market?
China holds the largest mine base, at an estimated 40,000 tons of 2025 output.[1] Hunan Gold is a major Chinese producer. Western supply comes from a handful of miners and smelters in the USA, Australia and Korea.
Which antimony companies have documented positions?
Thompson Falls smelting capacity expanded at United States Antimony Corporation.[4] Perpetua posted $139 million in financial assurance and began early works.[6] Larvotto started concentrate output at Hillgrove.[7] Korea Zinc raised direct exports from Onsan.[3]
What should compounders evaluate before approving an antimony supplier?
Buyer preference starts with particle size, purity, dusting and price stability. Origin now ranks beside grade, since China supplied 66% of US oxide imports over 2021 to 2024.[1]
How is antimony competition expected to change through 2036?
Western smelters will compete for DLA and compounder contracts as new mines ramp. Chinese converters will keep cost leadership on oxide. Recycled metal covered 12% of US apparent consumption in 2025, and lead-acid battery recyclers will raise that share.[1]
