The Stibnite Gold Project has been designed to use an abandoned mine site to produce gold and antimony. According to a release about the USFS decision, this is the only reserve of antimony within the United States. Antimony is mixed with other metals to form alloys that are used in batteries, semiconductors, technology applications, and more.
Stibnite is a historical mining operation that produced antimony for war efforts in the 1940s and 1950s and then was abandoned following a series of smaller gold operations. Perpetua's plan for Stibnite is "as much about restoring the site as it is mining it for the much-needed critical mineral antimony and gold," according to the company …

Although mining antimony is cheaper in China because of labour costs and the typically large deposits, the trend in declining production is set to endure.

Some antimony is produced as a by-product of smelting ores of other metals, mainly gold, copper and silver, in countries such as the United States, Canada, and Australia. Important amounts of antimony are yielded as a by-product of copper and silver mining. Numerous stibnite deposits occur in Idaho, Montana and Nevada.
Electrolysis is also widely used in the production and refining of precious metals, for instance, electrolytic gold is produced using hydrochloric acid as an electrolyte, known as the Wohlwill process, which produces gold at 99.5% purity. Further electro-refining using the Miller chlorination process can improve gold's purity to 99.999%.
