Good news!
"Until recently, antimony, which is often found in gold mines, was treated as detritus by gold miners. But that began changing last year, when China put in place heavy restrictions on exports of the element. That has led to prices quadrupling from two years ago, squeezing defense companies, which use antimony to harden bullets and strengthen armor-penetrating projectiles. Now, miners are dusting off sites that last produced antimony during the 20th century."
A stibnite specimen is shown. Stibnite is the predominant ore mineral of antimony, according to the United States Geological Survey. (Source)
