United States Antimony Corporation Provides Third Quarter Update on Antimony Shipments to the DoW

USAC expects the approximately 99%-pure antimony flake to improve the efficiency of its gas-fired furnaces.

Rhea-AI Summary

United States Antimony (UAMY) provided a third-quarter shipment update for the Defense Logistics Agency under its existing $245 million supply contract. The sole-source agreement covers military-specification antimony ingots. Antimony flake feedstock from its joint partner's Bolivian Hydrometallurgical facility arrived at the Thompson Falls smelters during the quarter under contractual offtake agreements.

The company said increased receipts of acceptable foreign material and expanded processing capability at its new Thompson Falls, Montana, facility are enabling increased DLA deliveries. Processing has also begun on Stibnite Hill, Montana, material mined late last year and this year. That material totals in excess of 400,000 pounds of antimony and is stockpiled at Radersburg, Montana. USAC expects this low-cost feed material to improve finished-product margins.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Key Terms

mil-spec, offtake agreements

2 terms

mil-spec technical

"Military Specification (MIL-SPEC) antimony ingot shipments"

A mil-spec is a military specification that sets strict technical and quality standards for products or components used by armed forces, like a blueprint for durability and performance under harsh conditions. For investors, a mil-spec label signals that a product meets government procurement requirements, which can open stable contract opportunities, imply higher production costs and margins, and create barriers to competitors — all of which affect a company’s revenue and risk profile.

offtake agreements financial

"contractual offtake agreements from its joint partner's"

An offtake agreement is a contract where a buyer agrees to purchase a set amount of a company's future production—such as minerals, energy, or manufactured goods—often before the product is made. For investors, these deals act like a guaranteed customer or advance order that reduces sales risk, helps secure project financing, and makes future revenue more predictable; think of it as a long-term subscription that stabilizes cash flow.

DALLAS, TX / ACCESS Newswire / September 30, 2026 / United States Antimony Corporation ("USAC," "U.S. Antimony," or the "Company"), (NYSE: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 an update on the Company's Third Quarter delivery of Military Specification (MIL-SPEC) antimony ingot shipments to the Defense Logistics Agency ("DLA") under its existing $245 million sole-source supply contract. USAC is the sole producer of MIL-SPEC (>99.6% pure) antimony ingots in the Western Hemisphere.

3rd Quarter and Near-term DLA Delivery Schedule

Antimony flake feedstock deliveries to USAC related to the Company's contractual offtake agreements from its joint partner's Bolivian Hydrometallurgical ("Hydromet") facility have occurred and landed at the Thompson Falls smelter(s) during the third quarter. Due to its high purity (~99%), antimony flake will significantly improve the efficiency of our gas-fired furnaces.

Mr. Gary C. Evans, Chairman and CEO of USAC stated, "As our receipt of acceptable antimony material continues to increase from foreign sources along with our expanded processing capability at our new facility located in Thompson Falls, Montana, our ability to continue increasing our antimony ingot deliveries to the DLA is occurring. This is the first period in our company's nearly 60 year history that we are fulfilling a significant and extremely important delivery of a finished product so vitally necessary to our military for use in many different products. Additionally, now that we have begun processing the Stibnite Hill, Montana, antimony material mined late last year and this year, which now totals in excess of 400,000 pounds of antimony and is presently located in stockpile at Radersburg, Montana; new low-cost USAC antimony feed material will begin further improving our finished product margins.

About USAC:

United States Antimony Corporation and its subsidiaries in the U.S., Mexico, and Canada ("USAC," "U.S. Antimony," the "Company," "Our," "Us," or "We") sell antimony, zeolite, and precious metals primarily in the U.S., Mexico, and Canada. The Company mines, purchases, and processes ore primarily into antimony oxide, antimony metal, antimony trisulfide, and precious metals at its facilities located in Montana and Mexico. Antimony oxide is used to form a flame-retardant system for plastics, rubber, fiberglass, textile goods, paints, coatings, and paper, as a color fastener in paint, and as a phosphorescent agent in fluorescent light bulbs. Antimony metal is used in bearings, storage batteries, and ordnance. Antimony trisulfide is used as a primer in ammunition. The Company also recovers precious metals, primarily gold and silver, at its Montana facility from third party ore. At its Bear River Zeolite ("BRZ") facility located in Idaho, the Company mines and processes zeolite, a group of industrial minerals used in water filtration, sewage treatment, nuclear waste and other environmental cleanup, odor control, gas separation, animal nutrition, soil amendment and fertilizer, and other miscellaneous applications. Beginning in 2024 and continuing in 2025, the Company acquired mining claims, real properties (patented claims) and leases located in Alaska, Montana, and Ontario, Canada in an effort to reduce the cost of third-party antimony ore purchases and to expand its product offerings.
