Management Comments

• "While management has worked tirelessly all of this year in our efforts to procure new antimony sources of quality raw ore for our two operating smelters, it is evident that there continues to be a worldwide shortage of this critical mineral."
• "Once we sort through the brokers, the traders, the promoters, and finally get to the actual source, we have to then assay the material and determine its ability to be processed. It also has to be in quantities that justify the financial and logistical resources required to actually get the material to our processing facilities."
• "As can be seen by todays press release, we are making substantial headway with multiple parties and country origins."
• "This range of sources substantially reduces our risk as evidenced by our recent issues with the Australian antimony ore."
• "At the same time, we are ramping up our own domestic supply from both Alaska and Montana, which will have substantially higher net margins."
• "These new antimony supplies dovetail nicely with our expansion efforts underway in Thompson Falls, Montana."
• "If our foreign supplies continue increasing as anticipated, we will then consider expanding our smelting capabilities at Madero (currently 200 tons per month) to accommodate this additional increase in anticipated inventory."
• "US Antimony is the only vertically integrated antimony company in the world outside of China. We are confident in our ability to meet the growing demand of our products for both our military and our industrial customers."

Industry Context

The announcement underscores the ongoing worldwide shortage of antimony, a critical mineral essential for various industrial and military applications, including flame retardants, batteries, and ammunition. The Company's efforts to diversify its global procurement sources (Alaska, Australia, Bolivia, Canada, Chad, Mexico, Montana) reflect the intense competition for critical mineral supplies, particularly with China actively seeking to secure antimony resources globally. USAC's unique position as the only vertically integrated antimony company outside of China highlights its strategic importance in the global supply chain, especially given the increasing demand from military and industrial customers. The challenges faced with impurities and customs delays are common in the complex international critical minerals trade.

Comparison to Industry Standards
