United States Antimony Corporation ("USAC," "US Antimony," or the "Company"), (NYSE:UAMY) (NYSE Texas:UAMY), a leading producer and processor of antimony, zeolite, and other critical minerals, and the only fully integrated antimony company in the world outside of China and Russia, announced today that it has begun commissioning of the newly constructed Thompson Falls antimony smelter back in May by firing up the first of nine new state-of-the-art gas fired furnaces. A total of five furnaces are anticipated to be commissioned by the end of this week. The commissioning process started by rotating the furnaces in an effort to get them all running properly so "bugs" could be quickly worked out. We have been finding a number of minor things to fix or modify, and these changes are being applied daily to each new furnace. As additional internal parts and heat exchangers are delivered by third party contractors to the property over the next few weeks, the entire new addition (nine total furnaces) is anticipated to be up and running by month end.
