United States Antimony Corp

A miner and processor of antimony, a metal used in flame retardants for electronics, plastics, and wiring. It's the only significant domestic producer of antimony in the United States, and also recovers gold and silver and sells zeolite for water filtration. Founded in 1968 as AGAU Mines, Inc. to mine gold and silver, it was reincorporated in Montana in 1970 to focus on antimony, and runs one of only three antimony smelters in North and Central America.
