Key Terms

defense production act, title iii, antimony trioxide, antimony trisulfide, +4 more

8 terms

defense production act regulatory

"awarded $27 Million by the Department of War under Title III of the Defense Production Act (DPA)"

A U.S. law that lets the federal government prioritize, allocate, and financially support the production and supply of goods and services needed for national defense or major emergencies. For investors, it can quickly change a company’s sales outlook and production plans by directing contracts, speeding approvals, or providing subsidies—like a city mayor telling factories which products to make during a crisis—so affected companies may see rapid revenue or cost shifts.

title iii regulatory

"under Title III of the Defense Production Act (DPA) to enhance, innovate, and expand"

Title III is the part of U.S. securities law that allows small companies to raise money from many ordinary investors through regulated crowdfunding platforms. It matters to investors because it opens access to early-stage private deals that were once limited to wealthy backers, while imposing legal limits and disclosure rules to reduce fraud and cap how much each person can invest. Think of it as a supervised online fundraiser with guardrails for both companies and everyday investors.

antimony trioxide technical

"USAC's unique expertise enables the production of multiple strategic antimony derivatives, including:Antimony Trioxide, used in flame retardants"

Antimony trioxide is a white powder used mainly as a flame retardant additive and as a raw material in metal alloys and certain plastics, ceramics and glass. For investors, it matters because its supply, regulatory restrictions, or health-and-safety concerns can affect costs and sales for manufacturers that rely on it—think of it as a common ingredient in building materials that, if restricted or scarce, could disrupt production and margins.

antimony trisulfide technical

"Antimony Trisulfide, critical to small and medium-caliber munitions, explosives, matches"

Antimony trisulfide is a chemical compound made from the metal antimony combined with sulfur; think of it as a stable material created by mixing two basic elements. It is used in products ranging from flame retardants and pigments to certain electronic and ammunition components, so changes in its supply, regulation, or production costs can affect manufacturers, miners and downstream businesses — making it a commodity of interest to investors tracking raw-material risk and price swings.

antimony metal technical

"Antimony Metal, used in semiconductors, lead-acid batteries, infrared sensors"

Antimony metal is a brittle, silvery-gray metalloid used as an ingredient in products like flame retardants, lead-acid batteries, solder, and certain electronics. For investors, it matters because its supply and price influence costs and profitability across several industries—think of antimony as a spice in industrial recipes: small amounts can be essential, and shortages or trade restrictions can push up costs or disrupt production for companies that rely on it.

vertical integration technical

"capable of full vertical integration across the supply chain from ore extraction"

Vertical integration occurs when a company controls multiple stages of its production or supply chain, such as making its own products and also distributing or selling them. This can help the company reduce costs and increase control over quality and delivery. For investors, it often signals a company’s effort to become more self-sufficient and competitive in its industry.

stibnite technical

"vertically integrate stibnite mining and processing from our Alaska claims"

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.

executive order regulatory

"as articulated in the March 20, 2025, Executive Order 14241 - Immediate Measures"

An executive order is a formal directive issued by a country’s chief executive (for example, a president or prime minister) that tells government agencies how to apply or enforce laws and policies without waiting for new legislation. It matters to investors because these orders can quickly change rules, permits, taxes, trade or regulatory enforcement—like a manager changing company policy overnight—creating risks or opportunities that can affect company costs, revenues and share prices.

Department of War Invests $27 Million for the Domestic
Extraction, Processing, and Refinement of Critical Materials

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

DALLAS, TEXAS / ACCESS Newswire / March 5, 2026 / United States Antimony Corporation ("USAC," "US Antimony," the "Company"), (NYSE:UAMY), announced today that as the only domestic processor of antimony and producer of finished antimony products in the United States, it has been awarded $27 Million by the Department of War under Title III of the Defense Production Act (DPA) to enhance, innovate, and expand domestic extraction, processing, and refinement of critical materials. These investments approved last year were delayed due to the government shutdown. This investment utilized funds from the Additional Ukraine Supplemental Appropriations Act of 2022. This award also supports the current Administration's goal to increase the production of processed critical minerals and other derivative products as articulated in the March 20, 2025, Executive Order 14241 - Immediate Measures to Increase American Mineral Production.

Using DPA Title III funds, the new recipient will ignite additional U.S. production of critical minerals and their derivatives, strengthening the Nation's defense supply chains:

• DOW's $27.0 million investment in USAC will fund the modernization and expand the company's capacity located in Montana to refine and produce antimony necessary for flame retardants, batteries, munitions, and other defense applications. In parallel, this investment will support USAC's initiative to establish domestic antimony excavation and extraction in the State of Alaska. By securing domestic feedstock, USAC has already positioned itself with its Montana mining activities as the only U.S.-based company capable of full vertical integration across the supply chain from ore extraction, processing, and to finished antimony products.

This is one of three investments made by the DPA Purchases Office totaling $58.5 million since the beginning of fiscal year 2026. USAC's recipient cost share of the $27 million award is $3.9 million (~14.4%). The MCEIP Directorate oversees the DPA Purchases Office.

This investment comes at a pivotal time for both the Company as well as our country. In September 2024, China, the world's leading supplier of elemental antimony and its compounds, announced a ban on exports of several critical minerals and metals, including antimony and its compounds. Simultaneously, the U.S. National Defense Stockpile is being depleted at an accelerated rate to support both our Country's initiatives as well as our allies in recent conflicts. The United States has an urgent need to rebuild and scale up its existing domestic capacity for antimony extraction, processing, and conversion to ensure long-term supply chain resilience and military readiness. On September 22, 2025, USAC was awarded a sole-source contract by the U.S. Defense Logistics Agency (DLA) Strategic Materials for up to $245 Million. (See Press Release dated September 23, 2025, which was subsequently increased to approximately $248 million in order to accommodate other divisions of government needs.)

USAC's unique expertise enables the production of multiple strategic antimony derivatives, including:

1. Antimony Trioxide, used in flame retardants, pigments, ceramics, plastics (including polyethylene terephthalate, or PET, the most used polymer in the packaging industry), enamels, rubber, and textiles.

2. Antimony Trisulfide, critical to small and medium-caliber munitions, explosives, matches, pyrotechnics, and solar panels.

3. Antimony Metal, used in semiconductors, lead-acid batteries, infrared sensors, and night vision technologies.

With over 50 years of experience, USAC remains the only U.S.-based operation capable of producing antimony products at a commercial scale. The U.S. government award announced today will fund our current expansion efforts which are almost complete along with the modernization of our existing smelter at the company's Thompson Falls facilities. Additionally, this award will further support the company's vertical integration of mining that has been initiated in both the States of Alaska and Montana. The current expansion of our Thompson Falls facility is anticipated to be completed by early April 2026, which will increase total output capacity to approximately 400-500 tons per month of finished product, depending upon quality of ore received.

Through our White Paper submitted to the Defense Industrial Base Consortium (DIBC) last year, we proposed a multi-phase project to expand our capabilities and vertically integrate stibnite mining and processing from our Alaska claims through our Montana production lines. Our commitment includes modernization of facilities, implementation of certain new technologies, and to support future stibnite anticipated from both domestic and international sources. We continue to be honored that we are in a position to play this very necessary role in rebuilding America's critical mineral independence with significant operational changes occurring at USAC this year.

USAC Chairman and CEO, Gary C. Evans went on to say, "When we first began hearing about China's impending critical mineral export ban back in 2024, we immediately initiated discussions with domestic end-users and as well as government stakeholders to assess the potential impact. The U.S. has historically relied too heavily on foreign sources for antimony, despite its role in munitions, fire protection, and emerging energy technologies. As the only domestic processor of antimony, USAC is uniquely positioned to further support our nation's strategic and commercial needs. This additional financial support announced today will allow us to continue accelerating our current expansion and in our operations as the only fully integrated antimony miner and producer located in the world, outside of China and Russia. This project expansion effort directly aligns with a continuum of U.S. goals to secure critical supply chains, advance domestic manufacturing, and build upon priorities formalized in Executive Orders 14241 and 14272 under President Trump's Administration. Our projects advance the goal of reducing U.S. dependency on foreign sources of critical minerals at a time when they are continuing to be withheld and used as bargaining chips by these foreign adversaries. Additionally, our efforts are geared to accomplish the goal of strengthening the U.S. industrial capabilities now for the benefit of our defense readiness as well as meet the continued industrial demands of our existing and new customers."
