United States Antimony Announces the Appointment of a New Independent Board Member Jon R. Marinelli

"The Critical Minerals and ZEO Company"

~ Antimony, Cobalt, Tungsten, and Zeolite ~

DALLAS, TX / ACCESS Newswire / November 24, 2025 / United States Antimony Corporation ("USAC," "US Antimony," 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, today provided additional updated information on the Company's Montana antimony mining activities.

As of late last week, truck number 50 brought raw antimony ore down off the mountain at Stibnite Hill in Montana. To-date, approximately 800 tons of antimony ore has been removed from the mountain. With additional snow and freezing conditions predicted for this week, our project on Stibnite Hill will likely be shut down soon until Spring thaw.

Specific material trucked down the mountain was selected on the basis of visual recognition of stibnite in the narrow flat dipping veins. The Company is awaiting assay results from samples collected by an independent geological consulting firm that was retained during the crushing operation at a contract flotation mill in Montana. These samples were subsequently submitted by the third-party consulting firm to an internationally qualified assayer. Based upon our initial observations in antimony recovery, it is anticipated that the flotation stage at the contact mill will produce concentrate that will meet minimum military specifications for antimony trisulfide used for primer ignitions. Presently, USAC is the only North American supplier of antimony trisulphide approved by the United States Defense Logistics Agency (DLA), for use in military primers.

To put this amount of material moved down Stibnite Hill in perspective, antimony feedstocks through the Thompson Falls smelter for the first nine months of this fiscal year (through September 30, 2025) were 1,010 tons or an average of 112 tons per month. Approximately 48% of this input contained antimony, or a total of 491 tons. USAC has in less than 45 days, moved approximately 800 tons of material for processing.

Commenting on this additional significant update, Joe Bardswich, Executive Vice President and Chief Mining Engineer of USAC, stated, "Our operations on Stibnite Hill, located directly adjacent to our existing smelter, provides 'proof of concept' of our original plans to use similar mining techniques to begin excavation of stibnite deposits from our vast Alaskan mining property holdings beginning early next year. While most of our competition likes to talk about what they plan on doing two to four years from now in the antimony business, we are putting rock in the box today and selling finished products to customers."

DALLAS, TEXAS / ACCESS Newswire / November 12, 2025 / United States Antimony Corporation ("USAC," "US Antimony Corporation," or the "Company"), (NYSE American:UAMY)(NYSE Texas:UAMY) reported today its third quarter and nine months ended September 30, 2025 financial and operational results.

Revenues for the first nine months of 2025 increased to $26.23 million, or a 182% increase of $16.92 million, compared to $9.31 million for the first nine months of 2024 . During the same period, cost of revenues increased 170% or $11.96 million. This in-turn allowed the Company's gross profit to more than triple with an increase of 219%, or $4.96 million to $7.22 million as compared to $2.26 million during the same nine-month period in 2024. Gross margin increased to 28% during the first nine months of 2025 from a 24% margin experienced during the same nine months of last year. This 4% increase in gross margin is before processing any of USAC's in-house antimony recently mined in Montana. Operating expenses were $11.76 million for the first nine months of 2025, which is an increase of $8.19 million compared to the same period in the prior year.

The Company incurred a net loss of $4.05 million for the nine months ended September 30, 2025, as compared to a net loss of $847k for the corresponding nine-month period in the prior year. Included in the net loss for 2025 was $5.18 million of non-cash expenses, which consisted primarily of $4.69 million of non-cash share-based compensation expense related to management and directors' stock grants that were expensed during this period after shareholder approval at the Company's annual meeting held on July 31, 2025, and $839k of non-cash depreciation and amortization expense.

Our antimony sales were $23.57 million for the first nine months of 2025, which is up $16.5 million, or 235%, over last year. This improvement was primarily due to an increase in the average sales price per pound over the two nine-month reporting periods, not increased volumes.

Our zeolite sales were $2.65 million for the first nine months of 2025, which is up $375k, or 16%, over the same period last year.

The Company's cash position, including its investment in securities (federal bonds), totaled $38.5 million at September 30, 2025, compared to cash only of $18.2 million at year-end 2024. During the first nine months of 2025, USAC dispersed $16.07 million of its cash on capital expenditure additions compared to only $223k during the same period in the prior year. The current year capital expenditure additions included $5.77 million for mineral rights purchases and $9.16 million for engineering, machinery, and construction services to expand the capacity of its existing smelting operations located in Thompson Falls, Montana. Also, during the first nine months of 2025, the Company received i) $20.95 million of net proceeds from the sale of its common stock in "at the market offerings" ii) $17.49 million of net proceeds from the sale of its common stock to one institutional investor and iii) $4.43 million of proceeds from the exercise of pre-existing common stock warrants. Then, subsequent to quarter end, in October 2025, the Company received additional net proceeds of approximately $16 million pursuant to "at the market offerings" and two direct offerings to select institutional investors in the amount of $26 million and $24 million, respectively, for total cash receipts of $66 million.

USAC's current antimony inventory year-to-date has all been acquired from international third-party suppliers and currently sits at record levels. As of September 30, 2025, inventory totaled 230 tons of antimony (both processed and unprocessed). The value of this inventory at today's Rotterdam market price is approximately $9.2 million at September 30, 2025, compared to $2.4 million last year at this time and $3.1 million at the year-end of 2024, both calculated at today's Rotterdam market price.

Today the Company is narrowing its revenue financial guidance for fiscal year 2025 and reiterating its 2026 revenue financial guidance:

2025 Revenues - $40 - $43 Million

2026 Revenues - $125 Million

Commenting on the Third Quarter and Nine Months Ended September 30, 2025 financial and operational results, Mr. Gary C. Evans, Chairman and CEO of US Antimony Corporation stated, "The third quarter marked a continued improvement in our overall financial performance. We successfully secured two major sales contracts over the last 60 days - a five-year, sole-source IDIQ contract with the U.S. Defense Logistics Agency valued at up to $245 million in September 2025 and a five-year commercial supply agreement with a large U.S. industrial fabric manufacturer valued at approximately $107 million announced yesterday. Both of these contracts provide significant long-term revenue growth and stability for our shareholders. Our success at finding new antimony ore at our recently re-opened mine in Montana, located adjacent to our operating smelter, has been quite significant. Since October 10th, we have moved 35 trucks and over 560 tons of antimony ore down the mountain. This new supply will provide significant margin expansion to our operations as compared to the material currently being acquired from international third parties. This should begin to be realized in our financial performance during the first quarter of 2026, as our expansion efforts are completed in January 2026. We continue our efforts to expand our operating base into other critical minerals. We look forward to announcing those increased accomplishments in the near future. As the only fully integrated antimony company in the free world (outside of China and Russia), our mission is to continue becoming the lowest cost producer of antimony products which insures our future viability. We continue down this path and anxiously anticipate future financial results to reflect that accomplishment."
