Analysis

The stock surged +11.8% in the session following this news. A strong positive reaction aligns with UAMY’s pattern of sizable moves on strategic acquisitions, where past deals saw an average move of 12.34%. The Radersburg flotation facility directly supports upstream antimony ore from Alaska and Montana and complements smelter expansion. However, investors have previously reacted negatively to capital-intensive updates, so enthusiasm could fade if integration costs or execution risks at the mill weigh on future results.

Key Terms

flotation, smelter, stibnite, tailings storage ponds, +4 more

8 terms

flotation technical

"a critical minerals flotation facility that closed on January 16, 2026."

Flotation is the process where a privately held business makes its shares available to the public by listing them on a stock exchange, commonly called an initial public offering (IPO). For investors it matters because flotation creates a market price and trading chance for those shares, signals a company's growth plans and need for capital, and changes how the business is governed — like a small shop selling ownership stakes to many new customers to raise money and spread risk.

smelter technical

"within 250 miles of our Thompson Falls smelter operation that is presently"

A smelter is an industrial plant that heats and processes mined ore to extract and produce usable metal (like copper, aluminum or nickel), turning raw rock into market-ready metal much as a kitchen turns raw ingredients into a finished meal. Investors care because smelters are costly to build and operate, they control how much refined metal enters the market, and their output, costs, and environmental or regulatory issues can directly affect commodity prices and company profits.

stibnite technical

"including stibnite, the primary antimony mineral."

Stibnite is a naturally occurring mineral made of antimony and sulfur (chemical formula Sb2S3) and is the main ore from which the metal antimony is extracted. It matters to investors because antimony is a raw material used in flame retardants, batteries, alloys and some electronic components, so discoveries, mining output or supply disruptions of stibnite can influence commodity prices and the prospects of mining and manufacturing companies — like finding a concentrated vein of a useful metal.

tailings storage ponds technical

"slurry flow through the facility to the tailings storage ponds."

Tailings storage ponds are engineered basins that hold the leftover watery slurry of crushed rock and chemicals after minerals are extracted in mining. They matter to investors because their condition affects a company's environmental liability, regulatory approvals, cleanup costs and ability to keep a mine operating; a failure is like a burst dam at a backyard pond, potentially causing large financial, legal and reputational damage.

centrifugal concentrator technical

"The Radersburg Mill has a centrifugal concentrator, mineral jig, and a shaking"

A centrifugal concentrator is a rotating machine that separates and concentrates heavier solids from liquids by spinning them so that dense particles move outward and collect in one place, like a salad spinner forcing water from lettuce. Investors care because it can raise recovery rates, cut processing costs, and shrink waste streams in industries such as mining, recycling, and wastewater treatment, directly affecting production efficiency, margins, and regulatory compliance.

mineral jig technical

"centrifugal concentrator, mineral jig, and a shaking table that can be used"

A mineral jig is a simple gravity-separation device used in mining to concentrate heavy ore particles by pulsing water and gently shaking material so denser minerals settle while lighter waste is washed away—think of a vibrating sieve that lets heavy bits sink. For investors, it matters because a jig can improve metal recovery, lower processing costs and environmental impact, and influence a mine’s productivity and profitability.

flotation cells technical

"into a series of tanks or "flotation cells" that have agitation and"

Flotation cells are industrial tanks used in mining to separate valuable minerals from crushed rock by making target particles attach to bubbles and rise to the surface like froth that can be skimmed off. For investors, they matter because their number, size, condition and efficiency directly affect how much metal a mine recovers, the cost per unit produced, and the scale of capital and operating expenses — essentially shaping production output and profitability.

hydrophobic technical

"Some reagents imbue a hydrophobic characteristic to the target mineral(s)"

Hydrophobic describes a material or surface that repels water, causing moisture to bead up and roll off instead of being absorbed. For investors, that property affects product performance, durability, packaging, manufacturing steps, safety testing and regulatory compliance—think of it as a raincoat for materials—so it can influence production costs, warranty claims, market appeal and the need for specific certifications.

"The Critical Minerals and ZEO Company"
~ Antimony, Cobalt, Tungsten, and Zeolite ~

DALLAS, TX / ACCESS Newswire / January 20, 2026 / United States Antimony Corporation ("USAC," "US Antimony," or the "Company"), (NYSE American:UAMY)(NYSE Texas:UAMY), a leading producer and processor of antimony, zeolite, and other critical minerals, and the only fully integrated antimony company in the world outside of China and Russia, announced today the closing of a property acquisition of a critical minerals flotation facility that closed on January 16, 2026. The property and equipment is located in Radersburg, Montana, between Helena and Bozeman, Montana, is fully operational, and was acquired for $4.75 million in cash. The Company has budgeted approximately $2 million in future capital expenditures to make specific equipment improvements to this facility.

This flotation facility is strategically located within 250 miles of our Thompson Falls smelter operation that is presently under substantial expansion of total capacity thruput. This significant enlargement and modernization of the new smeltering operation continues on track for a February completion and commissioning.

The Radersburg Mill is a mineral processing facility equipped with both gravity and flotation circuits enabling the concentration of many minerals including stibnite, the primary antimony mineral. The facility has crushing and grinding circuits that reduce the ore to small particles in order to "liberate" target minerals such as gold, silver, copper, tungsten or stibnite amongst many others. Water is added to the grinding and recovery circuits enabling a slurry flow through the facility to the tailings storage ponds. The existing tailings storage facilities are equipped with water recycling circuits.

Gravity concentration processes typically focus on gold recovery and concentration. Antimony and Gold are commonly associated with one another. The Radersburg Mill has a centrifugal concentrator, mineral jig, and a shaking table that can be used to make high-grade gold concentrates from gold-bearing ores. The gravity system is universal in that it can be used when appropriate or shut down when ores call for concentration solely by flotation methods.

Flotation is a standard process that involves introducing the slurry stream into a series of tanks or "flotation cells" that have agitation and bubble-producing mechanisms. Specific reagents are added to the slurry. Some reagents imbue a hydrophobic characteristic to the target mineral(s) which causes them to attach to bubbles and concentrate on the surface of the flotation cell in a mineral-laden froth. Other reagents help form and maintain the bubbles that form the mineral-laden froth. The froth builds up and overflows from the lip of the flotation cell so that it can be collected, filtered, and sent on for further refining steps. Many different minerals can be concentrated using flotation with the use of specific flotation reagents. The Radersburg Mill has recovered gold, silver, copper, lead, and zinc from localized ores but could also be used to concentrate other metals such as platinum, palladium, tungsten, cobalt, rare earth elements, and others.

Commenting on the acquisition of the Radersburg flotation facility announced today, Mr. Gary C. Evans, Chairman and CEO of USAC stated, "In order for us to concentrate our raw ore from both Alaska and Montana, we must first utilize a modern flotation mill to properly concentrate the material to a high enough level that we can then feed the various furnaces located in our smelters in order to produce mil-spec antimony trisulfide. This Radersburg acquisition announced today is perfectly suited for this required exercise. Additionally, it opens up the opportunity to mill other materials as it has done in the past (i.e. silver, gold, copper, etc.). We had previously leased a similar facility located in Philipsburg, Montana, but it became much too difficult to negotiate acceptable terms with the existing owners. We subsequently cancelled that lease in September 2025. Making necessary capital improvements to a leased facility versus one that we control 100% made this an easy decision. Our management team and board members know the Radersburg facility intimately from past experience concentrating other material while employed at previous companies over the years. This transaction announced today is another "leg on our stool" as a fully integrated antimony company in order to maximize profitability, control our destiny, and meet the ever-growing needs of our customers whether they be industrial or the federal government."
