The Army Reopens WWII-Era Critical Mineral Site

A gold mine in Idaho, once crucial for the U.S. "Arsenal of Democracy" during WWII, has been reopened by the U.S. Army and Perpetua Resources Inc.

The Stibnite Gold Project aims to harvest gold and antimony sulfide while rehabilitating the local environment.

"The Stibnite project currently holds the largest identified reserve of antimony in the U.S.,"

Maj. Reim, commanding officer of JPEO A&A and Picatinny Arsenal, noted that the project holds an estimated 148 million lbs. of antimony, one of the largest reserves outside of foreign control.
