US Antimony looks to ramp up antimony smelting facility

Antimony, a strategic minor metal used in flame-retardants, batteries and munitions, was added to China’s export restriction list in August, as it aimed to shore up the material in the name of national security.

Last year, China accounted for 48% of global mined output of antimony, according to the US Geological Survey (USGS).

Gary Evans, the co-chief executive officer of United States Antimony, said that its smelting facility at Thompson Falls was only running at 50% of its capacity due to a lack of supply.

“We’re working on changing that, and it’ll probably happen over the next 30 to 60 days. Those additional supplies will probably come from foreign sources – we’re talking to 12 different countries,” Evans said at the H.C. Wainwright 26th Annual Global Investment Conference.

The company has also leased a flotation facility in Philipsburg, Montana, that would help refine sub-par antimony and “bring it up to the levels it needs to be to make munitions-grade antimony,” Evans added.
