An Idaho mine will be the only US source of the key mineral antimony after 18 years of permitting [freebeacon.com]:

The Chinese government in recent weeks expanded its ban on exports [reuters.com] of a handful of minerals found in critical military and energy technologies in America. The move puts a spotlight on America's domestic mineral supplies, many of which are locked in years-long federal permitting and regulatory reviews.

One such case is a project located at an abandoned gold mine in the heart of Idaho [perpetuaresources.com]. That mine contains some of the nation's largest known deposits of the rare mineral antimony, which is among those affected by China's export restrictions. But after a staggering 14 years, the federal government has yet to give the Idaho project a green light to begin production.

Perpetua Resources, the developer of the Stibnite gold mine in Valley County, Idaho, first initiated study, engineering, and community engagement on the project in 2010. Since then, it has faced mountains of permit filings [usda.gov] and lengthy environmental reviews conducted by at least five separate federal agencies.

Experts and legislators say the federal regulatory and permitting behemoth with which developers like Perpetua must contend is both costly and detrimental to American national security. And they have pointed to the project as an example of why they say Congress must take up permitting reform legislation as soon as possible.

"China has weaponized the world's mineral supply chains," Rich Nolan, the president and CEO of the National Mining Association, told the Washington Free Beacon. "Again and again, Beijing has reached for the minerals lever to exert geopolitical leverage."

[...] Antimony, like the other minerals targeted by China, has significant defense and energy applications—it is a key component of munitions, night-vision goggles, and military uniforms and is required for both utility-scale and electric vehicle batteries.

The United States, though, imports 100 percent [usgs.gov] of its antimony supplies, 63 percent of which comes from China. China supplies the international market with about half of its antimony.

According to Perpetua, the Stibnite mine—which contains roughly 67,000 metric tons of antimony—could account for 35 percent of the nation's antimony demand in its first six years of production and fulfill long-term defense needs.
