Positives

• Acquisition of a fully operational critical minerals flotation facility for $4.75 million in cash.
• Strategic location of the Radersburg Mill within 250 miles of the Thompson Falls smelter, which is undergoing expansion.
• The new facility enhances the company's ability to concentrate raw ore from its Alaska and Montana operations.
• The facility's versatility allows for the concentration of a wide range of critical minerals and precious metals, including antimony, gold, silver, copper, tungsten, platinum, palladium, lead, zinc, and rare earth elements.
• The acquisition provides 100% control over the facility, allowing for efficient capital improvements, unlike the previous leased facility.
• Management's intimate familiarity with the Radersburg facility from past experience.
• The acquisition is described as "another leg on our stool as a fully integrated antimony company" to maximize profitability and control destiny.
• Thompson Falls smelter expansion is on track for February completion and commissioning.

Negatives

• The company previously cancelled a lease for a similar facility in Philipsburg, Montana, in September 2025 due to difficulties in negotiating acceptable terms, indicating past operational challenges in securing processing capacity.

Risks

• Fluctuations in the market prices and demand for antimony, zeolite, other critical minerals, and precious metals.
• Changes in domestic and global economic conditions.
• Operational risks inherent in mining and mineral processing.
• Geological or metallurgical conditions.
• Availability and cost of energy, equipment, transportation, and labor.
• Ability to maintain or obtain permits, licenses, and regulatory approvals.
• Changes in environmental and mining laws or regulations.
• Competitive factors.
• The impact of geopolitical developments.
• The effects of weather, natural disasters, or health pandemics on operations and supply chains.

Future Outlook

The company plans to invest approximately $2 million in capital expenditures to improve the newly acquired Radersburg flotation facility. The Thompson Falls smelter expansion is on track for completion and commissioning in February 2026. The acquisition is expected to enhance the company's ability to process raw ore from its Alaska and Montana operations and support its goal of becoming a fully integrated antimony company, maximizing profitability and meeting customer needs.

Management Comments

• "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.)."
• "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."

Industry Context

This acquisition positions United States Antimony Corporation as a more vertically integrated player in the critical minerals sector, particularly for antimony, outside of dominant producers like China and Russia. The focus on processing capabilities for a wide range of critical minerals (antimony, tungsten, rare earth elements) and precious metals (gold, silver) aligns with global trends emphasizing supply chain security and diversification for strategic resources. The investment in a fully operational facility and planned upgrades suggests a move to enhance domestic processing capacity, which is a key theme in critical minerals policy in the U.S.

Comparison to Industry Standards

• The filing does not provide specific comparable companies, projects, or results to assess the acquisition against global benchmarks.
• The acquisition of a fully operational flotation facility for $4.75 million, with an additional $2 million budgeted for improvements, represents a strategic investment in processing infrastructure. Without specific industry transaction multiples for similar facilities or detailed operational metrics, a direct quantitative comparison is not feasible based solely on this filing.
• The company's claim of being the "only fully integrated antimony company in the world outside of China and Russia" suggests a unique market position, making direct comparisons challenging.

Stakeholder Impact

• Shareholders: Potential for increased profitability and long-term value due to enhanced operational control, vertical integration, and diversified processing capabilities. The cash outlay and future capex represent an investment that could yield returns.
• Employees: Potential for job security or creation at the Radersburg facility and the expanded Thompson Falls smelter.
• Customers: Improved ability to meet the "ever-growing needs" of industrial and federal government customers for antimony and other critical minerals, potentially leading to more reliable supply.
• Suppliers: The facility will process raw ore, potentially benefiting suppliers of such materials from Alaska and Montana.
• Creditors: The cash acquisition and planned capital expenditures represent a significant investment, which could impact short-term liquidity but aims for long-term financial strength.

Next Steps

• Complete approximately $2 million in budgeted capital expenditures for specific equipment improvements at the Radersburg facility.
• Complete and commission the substantial expansion and modernization of the Thompson Falls smelter operation in February 2026.
• Utilize the Radersburg facility to concentrate raw ore from Alaska and Montana operations.
• Explore opportunities to mill other materials at the Radersburg facility, such as silver, gold, and copper.
