Montana antimony smelter expands amid federal push for domestic sources
Thirteen miles west of Thompson Falls and the banks of the Clark Fork River, a dirt road leads to a cluster of weathered green buildings and rusted remains of mining operations long quiet, until recently.
The humming comes from furnaces blasting pieces of slag into molten metal. This is Stibnite Hill, a smelting facility nestled in the Coeur D’Alene mountains. Inside, Plant Manager Rob Hill is in charge.
“This is what’s called sodium antimonate. It’s like wet sand. We run it with coal and soda ash into this furnace. It’s about 60 percent antimony.”
Hill works for United States Antimony Corporation, or USAC. It’s a small company that has quietly operated here since 1969. Now, that’s changing.
Antimony is an ingredient used in certain military applications, including flame retardants, infrared sensors and nuclear weapons.
Antimony is an ingredient used in certain military applications, including flame retardants, infrared sensors and nuclear weapons. As the Trump administration’s policies to bolster domestic mineral extraction have rolled out, the lesser-known metalloid took center stage.
“We became literally the only game in town so we really had to start running,” Hill says.
Stibnite Hill contains the only smelting facility for this material in the country. As a result, USAC was recently charged with replenishing domestic stockpiles. The project raises hopes and concerns for locals who have experienced the impacts of mining industries in western Montana.
For several decades, the U.S. has relied on foreign imports for antimony. Recent trade wars have compromised those imports.
In 2023, China, Russia and Tajikistan controlled about 90 percent of global antimony production. In December 2024, China banned all exports of it to the United States. That ban has since been lifted, but trade today remains stringent.
Last year, United States Antimony Corporation won a $248 million sole-source contract to resupply the federal government. CEO Gary Evans says they were the only company qualified to bid.

“When the government needed more antimony ingots, which are used as an inventory supply for future wars, they contacted us.”
The company grew significantly over the last three years. Their revenues more than doubled in 2025, as did their stock value. Most of that growth came prior to their first antimony deliveries to the federal government.
Montana Gov. Greg Gianforte attended the groundbreaking ceremony and issued a press release supporting the company’s growth.
“We’ve been able to basically take an older, sleepy company and revitalize it with a new board, new management team and new directions,” Evans says.
The goal is to smelt 400 tons of antimony per month, ideally with ore mined from Montana, Idaho or Alaska. The expansion project cost $20 million and will add about 25 new jobs.

The expansion project cost $20 million and will add about 25 new jobs.
One January morning, Plant Manager Rob Hill stands next to a cylindrical stone furnace, roaring with heat.
“What we need to do is get the antimony out of it,” he says. “We just load it into there, heat it up, it melts down. We’ll pour this whole thing up, this whole furnace will pour into these molds …”
In the next room, wooden pallets are stacked with dozens of shiny, grey antimony ingots.
“There’s over 100,000 pounds sitting here right now,” Hill says.
Their primary role today is smelting, but officials say they plan to reopen the underground antimony mine here too. Company officials say some surface mining has already begun.
Just down the road, Kevin Bush owns the Wild Coyote Saloon, a restaurant, bar and campground. He says the uptick in activity has been good for business.
“I thought it was good, we needed jobs in this area, so yeah, I had no problems with it.”
Inside the saloon, Plains-local Medric Jones sips a drink with his wife. He grew up a half hour from Thompson Falls and remembers mines supplying most of the jobs around.
“That’s jobs for the people in the middle of nowhere. It’s jobs for these people, us people,” Jones says.
But the legacy of mining in the region also spurs concerns. Prospect Creek, a tributary of the Clark Fork River that runs adjacent to Stibnite Hill, is already on the state’s list of impaired waterways due to mining pollution.
Cesar Hernandez is with grassroots conservation organization, the Cabinet Resource Group.
“The organization I represent is not against mining, but if it has to be done it needs to be done right,” Hernandez says.
He’s concerned about any mining projects approved under an era of weakened environmental protections and mining regulations.
“This isn’t just an issue of jobs and big money, but there will be increasing impacts from whatever goes on up at the mine.”
U.S. Antimony Corporation officials responded to these concerns saying they plan to “put the land back” in better shape than it was before.
Back in Thompson Falls, Robert Hill reflects on his 32 years with the company. He says the rapid growth has been impactful.
“This little backwoods Montana rural company is suddenly a hub of some very, very important materials, and we’re a name and we are not used to that. We really aren’t. It’s a unique position to be in, for sure,” Hill says.
The full expansion is estimated to be complete by the end of April. They plan to provide $75 million worth of antimony to the government in 2026.
Requests for interviews with local government officials about the project were denied.

Planning For Life After Coal Cost a Montana County Commissioner His Seat – Inside Climate News
Robert Pancratz couldn’t believe it.
The Musselshell County commissioner had been defeated in the Republican primary for his seat by a two-to-one margin earlier this month. Mark Olson, who lives in Musselshell and serves as the undersheriff in Golden Valley County, won by 26 percentage points.
“That just blew me away,” Pancratz said. “All of my campaign, I had not a hint that there was that much opposition.”
At stake, from Pancratz’s perspective, is the fiscal future of his community, which includes Roundup, Montana, home to Montana’s only longwall coal mine. The mine, owned and operated by Signal Peak Energy, sits on the eastern side of the continental divide in a staunchly conservative part of the state, where its presence provides jobs and its profits generate taxable revenue for local governments. (The vast majority of its coal, the dirtiest fossil fuel, goes to markets in Asia.)
But that revenue could potentially be diminished by tens of millions, according to calculations by Pancratz, if a bill introduced by U.S. Sen. Steve Daines, R-Mont., passes Congress. The Crow Revenue Act would convey federally held coal to Signal Peak through a land transfer to a private intermediary, depriving Musselshell County of its share of the taxes Signal Peak Energy pays to mine coal on federal land.
If the Crow Revenue Act does not pass Congress, Signal Peak says it could be forced to shut down if it loses a lawsuit in the U.S. District Court for the District of Montana challenging the “energy emergency” the Trump administration used to grant the mine access to federal coal. That outcome would wipe out all the mine’s tax revenue and hundreds of jobs, the company claims. This month’s election hinged on Pancratz’s position on the bill and, by extension, the mine.
Musselshell County’s three commissioners, Mike Goffena, Mike Turley and Pancratz support keeping the mine open. But they also fear Musselshell County would need to raise taxes and cut services to balance its books if the Crow Revenue Act passes as written. After studying the county’s finances, Pancratz, who works as a risk analyst consultant, concluded that the county could lose as much as $11.6 million if the Crow Revenue Act passes and the price of coal is high. The commissioners have lobbied for changes to the bill that would guarantee the county some revenue from the land transfer.

Pancratz says he was just doing his job.
“As a risk manager, I have to develop a contingency plan for the possibility that the long-term stream of coal revenue could be disrupted or ended,” he said. “We needed to have a plan to effectively transition to other revenue sources. When I used the word transition, they took that as I was an environmentalist that was against coal.”
“Why anybody would have a problem with that is baffling to me. But that’s what happened.”
According to Pancratz, Signal Peak Energy branded the men as environmentalists who want to see the company shut down forever and this willful mischaracterization played a large role in his defeat.
“The picture they painted of me was totally false,” he said.
In a recording of a commissioner meeting posted to a local Facebook group by a Signal Peak Energy employee less than a month before the election, Pancratz, Goffena and Turley can be heard strategizing how to express their concerns about the Crow Revenue Act to Daines, whom they describe as unresponsive to their concerns.
Pancratz suggests asking for a $100 million endowment to transition from coal to “scare” Daines and Signal Peak Energy. Turley states that with funding at that level, they wouldn’t care if the mine was open or not.
“Exactly,” Pancratz responded.
Comments on the video show viewers expressing outrage that the commissioners would “play chicken” with the future of the mine, which provides hundreds of jobs in the surrounding area.

Pancratz said the conversation was recorded without the commissioners’ knowledge. Montana is a two-party consent state, meaning all parties must be aware of and consent to a recording, but he allowed that it was possible one of the commissioners forgot to close a virtual public meeting after it concluded.
Pancratz said the conversation occurred when the commissioners found out there would be no money in the Crow Revenue Act for the county. The bill’s supporters, including Signal Peak Energy, had told them that the county would not lose any revenue under the bill, he said.
“We were upset because we felt we’d been lied to,” Pancratz said.
Signal Peak Energy did not respond to a written message and phone call seeking comment. For a time after Signal Peak took over the mine in the late 2000s, it was plagued by malfeasance, including embezzlement, a faked kidnapping and safety and environmental violations, according to reporting by The New York Times.
Olson said he entered the race due to a “lack of transparency” from the commissioners over how the county was spending its money.


But the mine played a role in his decision to run, too. As he was weighing his options, Olson said his cousin, Alan Olson, a former state legislator and former executive director of the Montana Petroleum Association, visited him and urged him to run to support the mine. After that conversation, he was convinced the mine’s survival depended on the Crow Revenue Act passing, and that trying to amend it would jeopardize the legislation.
“The more money we can get for the county, the better, but I don’t think it’s worth risking the mine closing,” Olson said. Losing federal revenue was better than losing all the jobs and the tax base if the mine closes, he concluded.
Olson added that Parker Phipps, Signal Peak Energy’s CEO, has briefed him on the mine’s fiscal relationship with Musselshell County.
Olson’s background in law enforcement could add a new perspective to the county commissioner meetings, given Goffena and Turley’s background in ranching, he said, but the minutiae of the county’s budget will be new to him.
“I am by no means an expert in any of this stuff,” he said.
Some worry that, with the mine facing a lawsuit, an unpredictable global coal market and the uncertain future of the Crow Revenue Act, the commissioners cannot afford to lose momentum in their efforts to attract new industries to the area.
Olson’s win in the primary will “set [economic diversification planning] back long term,” Nicole Borner, a former Musselshell County commissioner, who thinks Olson was hand-picked by the Signal Peak Energy to run and is not informed about what the job entails.
“We will always just have a few crumbs to duct tape a few issues,” she said. “We’ll never be able to fix the prior forty years of being in a coal bust and our infrastructure just literally falling apart.”
Olson will likely run unopposed in the general election.
In his remaining time in office, Pancratz said he will continue to push for economic diversification in Musselshell County. He holds no animosity towards Olson, who calls Pancratz “a wonderful guy.” Instead, he laments not addressing concerns over his position on the mine sooner in the campaign. But he believes Signal Peak Energy’s political and social influence—the company operates a charity in the region—is what swayed the election.
“You can’t say anything that even remotely implies that you’re trying to prepare the county for the possibility that coal revenue may not be steady or high … There’s this attitude that the county is in debt to that coal mine. And the message I tried to get out is, it’s more the reverse,” Pancratz said.
“I personally don’t believe the mine really cares about the county.”
