***United States Antimony Corporation: History, Present Position, and Prospects to 2030***

### Information Horizon

This analysis incorporates verified disclosures through the company's second-quarter 2026 results released August 11, 2026 (covering the quarter ended June 30, 2026), the company's August 5, 2026 mining update, and China's November 2025 suspension of its antimony export prohibition. The most recent market datum incorporated is the UAMY share price of roughly $4.92 to $5.17 on August 12, 2026, following the second-quarter guidance reduction \[1\]\[22\]. Antimony price references are anchored to Fastmarkets and Argus assessments through mid-2025, with 2026 spot direction inferred from the company's realized-price disclosures. Where subsequent events (a further Chinese policy shift, a DLA delivery-acceptance milestone, a new federal award) postdate this horizon, the conclusions below may be superseded.

## 1\. Summary

United States Antimony Corporation is three businesses wearing one ticker. It is a 58-year-old micro-cap smelting operator with a long base rate of marginal economics; it is one of very few non-Chinese antimony processing nodes and therefore a beneficiary of Western supply-chain anxiety; and it is a merchant processor whose realized margin is set by a thinly traded minor metal whose price is governed substantially by Chinese export policy. The second-quarter 2026 results demonstrate the tension: revenue of $7.93 million, a gross margin of 7 percent, and a full-year revenue guidance cut from $125 million to $60 to $75 million, driven not by demand but by an antimony price collapse from a realized $28.32 per pound a year earlier to $13.70 per pound \[1\]\[22\].

The central finding is that UAMY's equity has been repriced as a defense-policy and critical-minerals beneficiary while its unit economics remain those of a price-taking smelter with a variable input cost and, until recently, no captive ore. The company's valuation (a market capitalization that reached roughly $1.5 billion in April 2026 against trailing revenue near $32 million) embeds an integration-and-scale thesis that is largely unproven \[41\]\[38\]. The load-bearing uncertainties are four: the durability of the antimony price at levels that clear the hurdle rates of the Thompson Falls expansion, the Radersburg mill, and the hydrometallurgical joint venture; the pace at which company-mined ore displaces purchased feedstock; the conversion of the $245 to $248 million Defense Logistics Agency contract ceiling into inspected, invoiced revenue; and the reversibility of the Chinese export restriction that created the price spike in the first place.

The supply-chain thesis is more robust than the equity thesis. Even at depressed prices, a domestically controlled, defense-qualified antimony processing capability has strategic value that federal instruments are actively subsidizing. The investment thesis holds only if antimony stabilizes materially above the roughly $10 per pound the company's chief executive anticipated for the balance of 2026, and if captive ore from Stibnite Hill and Alaska delivers the threefold margin uplift management asserts \[22\]\[8\]. Both theses break if China's November 2025 easing persists and Chinese oversupply drives Western prices back toward pre-2024 levels while the company continues to fund capital expansion through equity dilution.

## 2\. Corporate History and Structural Evolution

### 2.1 Founding and the primary-mining era

The corporate lineage begins with AGAU Mines, Inc., incorporated in Delaware in June 1968 to mine gold and silver; United States Antimony Corporation was incorporated in Montana in January 1970 to produce antimony products, and AGAU was merged into USAC in June 1973 \[7\]. The company began mining antimony at the Stibnite Hill Mine near Thompson Falls, in Sanders County, Montana, in 1968 to 1969, working narrow, shallow-dipping stibnite veins from twenty-three drifts using room-and-pillar methods \[6\]\[8\]. Concentrates were sold to smelters until 1971, converted to metal by the English precipitation method and later electrowinning through 1976, and from 1977 to 1983 converted to sodium antimonate sold to the television-glass industry as a fining agent \[6\]. In December 1983 the company suspended antimony mining when imported feedstock became more economical, and for the next four decades USAC operated principally as a processor of purchased ore and byproduct feed \[7\].

This history establishes the base rate that frames the present transformation. For most of its existence USAC was a marginally profitable or loss-making small-cap dependent on the antimony price and on third-party feedstock, not an integrated miner with a resource margin.

### 2.2 Diversification: zeolite and Mexican smelting

In 2000 the company formed a 75 percent-owned subsidiary, Bear River Zeolite Company, to mine and market clinoptilolite zeolite from a deposit in southeastern Idaho; it constructed a plant in 2001 and acquired the remaining 25 percent in 2002 \[7\]. Bear River Zeolite has since operated as an independent industrial-minerals business serving soil-amendment, water-filtration, animal-nutrition, and environmental-remediation markets. In 2005 and 2006 the company established Mexican subsidiaries (Antimonio de Mexico and United States Antimony, Mexico) to develop antimony properties and to operate the smelter at Madero, in Coahuila, Mexico, supported by flotation milling at Puerto Blanco \[7\]. Madero has been idled and recommissioned repeatedly as antimony prices and feedstock availability fluctuated. In 2018 the company acquired the former Lanxess entities, including Stibnite Holding Company US Inc. and Antimony Mining and Milling US LLC, consolidating control over the Stibnite Hill ground \[7\].

### 2.3 The 2023 to 2024 leadership transition and repositioning

The current strategy dates to the arrival of Gary C. Evans, a serial energy-sector entrepreneur who joined the board in November 2022, became Chairman in July 2023 when John Gustavsen stepped down as Chairman while remaining chief executive, served as Co-CEO from March 2024, and assumed the sole chief executive role effective December 9, 2024 \[19\]\[20\]\[21\]. Evans is a promotional, capital-markets-oriented executive whose background (three energy companies taken public, prior chairmanship of Novavax) is legible in the company's subsequent conduct: aggressive equity issuance, a rapid string of acquisitions, and heavy investor-relations activity \[21\]. In December 2024 the board relocated the corporate headquarters from Thompson Falls, Montana to Dallas, Texas, noting that no executives or board members resided in Montana \[20\]. Joe Bardswich serves as Executive Vice President and Chief Mining Officer, and Richard Isaak as Senior Vice President and Chief Financial Officer \[21\].

The transformation coincided with, and was enabled by, the December 2024 dislocation in the antimony market. As the company itself states, "the antimony market shifted dramatically from a ban on antimony exports from China, leading to commodity prices reaching record highs," at which point management moved "quickly to scale, upgrade, enhance, and innovate its processing facilities" \[6\]. The strategic pivot is therefore better understood as an opportunistic response to a policy-driven price shock than as a long-planned industrial build-out.

### 2.4 Listing history

UAMY's primary listing is on NYSE American under the ticker UAMY; the company added a dual listing on NYSE Texas effective July 1, 2025, retaining NYSE American as its primary venue and the same ticker \[42\].

### 2.5 The historical financial record

The two-decade base rate is one of small revenue and recurrent losses. Reported revenue was $7.75 million in 2021, $11.04 million in 2022, $8.69 million in 2023, $14.94 million in 2024, and $39.26 million in 2025 \[39\]\[41\]. Gross profit swung from $0.84 million in 2021 and $2 million in 2022 to a gross loss of $3.34 million in 2023, then back to $3.47 million in 2024 and $8.43 million on a trailing basis into 2025 \[39\]. The company recorded a net loss of roughly $6.35 million in 2023, a reduced net loss of about $1.73 million in 2024, and a net loss of approximately $4.35 million in 2025 \[21\]\[41\]. Against this history, the 2025 revenue jump reflects the antimony price spike far more than a step-change in volumes, and the 2026 reversal (a first-half net loss of $11.18 million versus prior-year net income of $0.73 million) demonstrates how completely the model is levered to a single price \[1\].

## 3\. Antimony: Scientific, Metallurgical, and End-Use Background

### 3.1 Mineralogy and extraction

The dominant ore mineral is stibnite (antimony trisulfide, Sb2S3), typically hosted in low-temperature hydrothermal quartz veins and replacement bodies, frequently in association with gold, as at Stibnite Hill and at the deposits of UAMY's competitors \[8\]\[43\]. Two principal pyrometallurgical routes convert ore to product. Sulfide concentrates or high-grade ore are subjected to volatilization roasting to produce crude antimony trioxide, which is refined to the flame-retardant-grade oxide; alternatively, reduction smelting (historically by iron precipitation, in which molten iron displaces antimony from the sulfide, or by reverberatory and blast-furnace practice) yields antimony metal \[43\]. Purified antimony trisulfide crystal for military primer compositions is synthesized to stringent specification from concentrate, a capability the company demonstrated with Department of Defense qualification of trisulfide sourced from its Mexican operations in 2023 \[46\]. Hydrometallurgical routes, in which antimony is leached (for example as sodium thioantimonate) and recovered by electrowinning, offer lower-emission processing of complex or lower-grade feed and underpin the company's Idaho joint venture technology \[43\]\[24\].

### 3.2 End-use demand and substitutability

Application shares are frequently asserted without vintage or source, and the estimates themselves diverge; the disciplined figures are the USGS domestic splits. In 2024 the leading US uses were metal products, including antimonial lead and ammunition, at 40 percent; flame retardants at 39 percent; and nonmetal products, including ceramics, glass, and rubber, at 21 percent \[16\]. Global estimates vary by assessor: analyses drawing on Roskill and Project Blue place flame-retardant synergists (antimony trioxide used with halogenated compounds) at roughly 50 to 60 percent of a global consumption base of about 85,000 to 95,000 tonnes per year, while Future Market Insights puts flame retardants at nearly 42 percent of global antimony demand and Market Data Forecast at 48.3 percent for 2024, with the share declining over time as defense and photovoltaic demand have grown \[44\]. Other material uses are lead-antimony alloy grids in lead-acid batteries, clarifying and fining agents in photovoltaic and specialty glass, antimony trisulfide in ammunition primers and tracer and infrared-decoy compositions, indium antimonide and gallium antimonide in infrared detectors and semiconductors, and antimony trioxide as a polymerization catalyst in polyethylene terephthalate.

Substitution elasticity is the principal long-run demand risk and is genuinely low across most applications. In flame retardants, aluminum trihydroxide and magnesium hydroxide can substitute but require two-to-four-times loading and a six-to-twelve-month polymer requalification cycle, so compounders generally absorb price shocks rather than reformulate \[44\]. In battery alloys, combinations of calcium, copper, selenium, sulfur, and tin substitute, and design changes have already reduced antimony intensity per battery, but the segment is structurally durable because internal-combustion fleets continue to grow in emerging markets and every electric vehicle retains a 12-volt lead-acid auxiliary \[16\]\[44\]. In munitions primers, antimony trisulfide remains effectively irreplaceable: industry estimates hold that a large share of military munitions require it, and decades of research have not produced a qualified alternative that meets specification \[44\]\[45\]. The USGS lists selected organic compounds and hydrated aluminum oxide as flame-retardant substitutes and chromium, tin, titanium, zinc, and zirconium compounds as substitutes in chemicals, but characterizes none as a like-for-like replacement \[16\].

### 3.3 Secondary supply

Recycling is a material and stabilizing element of supply. In the United States, secondary antimony is recovered chiefly as antimonial lead from spent lead-acid batteries at secondary lead smelters, and in 2024 this supplied about 15 percent of estimated domestic apparent consumption (revised downward to roughly 12 percent for 2025); secondary production was about 3,500 tons, valued at roughly $73 million \[16\]. Because recycling is tied to the lead-acid battery loop rather than to primary antimony mining, it provides a partial hedge against primary-supply disruption but cannot scale quickly to offset a Chinese export shock.

## 4\. Asset Base and Operational Capability

The portfolio must be disaggregated. The company presents itself as "the only fully integrated antimony company in the world outside of China and Russia," but the actual condition in mid-2026 is a small producing core (two smelters plus a zeolite mine), a nascent captive-mining effort, and a large collection of early-stage exploration and optionality \[1\]\[35\].

### 4.1 Thompson Falls, Montana smelter

Thompson Falls is the operating heart of the company and one of the two North American antimony smelters it controls. An expansion begun in May 2025 is designed to raise finished-product capacity from roughly 75 tons per month to about 230 tons per month across nine furnaces, with roughly 80 percent of the expanded capacity reached by mid-July 2026 \[8\]\[26\]. Management has described a longer-run target well above this level when combined with downstream capacity, but the 230-tons-per-month figure is the verifiable expansion objective, and it is contingent on furnace commissioning and ore quality \[26\]. The status of any renovation of the older facility is not separately quantified in the record reviewed, and the evidence base on that specific item is thin.

### 4.2 Madero smelter, Coahuila, Mexico

The Madero smelter has been recommissioned to process internationally sourced feedstock arriving through Mexican ports, and management has linked further Madero expansion to the availability of that international supply \[23\]\[6\]. Because the plant sits in Mexico, its output moves under the United States-Mexico-Canada Agreement; the record reviewed did not surface a specific tariff dispute affecting antimony metal or oxide (US normal-trade-relations duties on antimony ore, oxide, and unwrought metal are free), so the USMCA position appears benign but is not deeply documented here \[16\]. Feedstock for Madero is predominantly purchased third-party and byproduct material rather than company-mined ore.

### 4.3 Radersburg flotation mill, near Toston, Montana

The Radersburg mill was acquired in the first quarter of 2026 for approximately $4.8 million and is in a commissioning rather than a producing state, being outfitted with an on-site laboratory to accelerate assay work; it is intended to concentrate ore from Stibnite Hill and Alaskan sources before smelting at Thompson Falls \[2\]\[26\]. Throughput has not been independently quantified.

### 4.4 Bear River Zeolite, Preston, Idaho

Bear River Zeolite is the one unambiguously producing, cash-generative non-antimony business. In the second quarter of 2026 [zeolite](https://en.wikipedia.org/wiki/Zeolite?ref=datadeep.tech) revenue grew 110 percent year over year to $1.9 million on a 114 percent increase in tons sold, a bright spot against the antimony segment's price-driven weakness \[1\]. Its economics are independent of the antimony price and provide a modest, stable revenue floor, though at a scale too small to offset antimony volatility.

---

**4.4.1 What Zeolites Actually Do, and Why the Natural Segment Is Small**

Zeolites are hydrated aluminosilicate minerals whose microporous crystalline framework holds loosely bound cations that exchange readily with cations in a contacting solution, giving the material simultaneous adsorption, ion-exchange, and molecular-sieving function. Roughly fifty naturally occurring species have been identified, but only chabazite, clinoptilolite, erionite, mordenite, and phillipsite are both commercially useful and abundant \[52\]. Bear River Zeolite produces clinoptilolite, the dominant natural species by tonnage.

World natural zeolite mine production was an estimated 1.3 million tons in 2025, led by Slovakia at 280,000 tons, Georgia at 240,000 tons, the Republic of Korea at 160,000 tons, China at 150,000 tons, Russia at 130,000 tons, and Indonesia at 120,000 tons; United States production of 80,000 tons from seven mines represented roughly 6 percent of the world total \[53\]. Domestic sales of 77,000 tons in 2025 went principally to animal feed at 42 percent and odor control at 15 percent, with the remainder distributed across soil amendment, water purification, pet litter, wastewater treatment, absorbents, aquaculture, and desiccants \[53\]. The USGS estimates an average domestic unit value of $200 per ton for 2024, up from $125 in 2021, within a reported range of $50 to $300 per ton \[53\]. Applying that unit value to 2025 sales implies a United States natural zeolite market on the order of $15 million at the mine gate, a figure that frames the segment's scale but is not directly comparable to company-reported revenue, which reflects delivered, packaged, and surface-modified product rather than bulk ex-works material.

Published estimates of the broader "zeolite market" ranging from $3.4 billion to $19.7 billion are not measurements of this business \[54\]\[55\]. That sixfold divergence reflects inconsistent scope definitions across commercial research vendors, and the values are dominated by synthetic zeolites, which the USGS notes account for nearly all United States trade in the commodity and which serve fluid catalytic cracking, detergent builders, and molecular-sieve separations \[53\]. Natural and synthetic zeolites are substitutes in some applications and compete directly, but they are not the same market, and readers should not map synthetic-inclusive market sizing onto Bear River's economics.

The most technically demanding established application for natural clinoptilolite is radioactive effluent treatment. Cesium-137 and strontium-90 are among the most abundant fission products in liquid nuclear waste, and clinoptilolite is selective for both, thermally stable, and radiation tolerant, since its framework does not degrade under cesium and strontium irradiation \[56\]\[57\]. British Nuclear Fuels commissioned the Site Ion Exchange Effluent Plant at Sellafield in 1985 using clinoptilolite to strip cesium and strontium from water bodies before sea discharge, and the technology was applied again after the 2011 Fukushima Daiichi accident, which released approximately 10 petabecquerels of cesium-137 \[58\]. The economically relevant constraint is that only high-grade clinoptilolite qualifies for nuclear service, which makes this a specification-premium submarket rather than a volume opportunity, and which has prompted research into activating and upgrading lower-grade material by chemical pre-treatment, milling, and flotation \[57\].

Emerging applications sit mostly on the synthetic side of the divide, which limits their direct relevance to a natural zeolite producer but indicates where the material class is heading. Copper-exchanged synthetic chabazite (Cu-SSZ-13) was commercialized around 2010 as the selective catalytic reduction catalyst for diesel nitrogen oxide abatement and is now standard in heavy-duty vehicles, while the silicoaluminophosphate analogue SAPO-34 is applied commercially in methanol-to-hydrocarbons conversion \[59\]. [Sorption thermal energy storage](https://www.sciencedirect.com/science/article/abs/pii/S1359431126023343?ref=datadeep.tech) is the most active frontier: zeolite 13X charged by driving off water using low-grade industrial waste heat below roughly 200 degrees Celsius has demonstrated energy storage densities exceeding 110 kilowatt-hours thermal per cubic meter, and a 2026 preprint proposes trucking charged zeolite to data centers to displace compression chillers, with claimed cooling power reductions of up to 86 percent \[60\]\[61\]. That claim is preliminary and has not been demonstrated at commercial scale. Digital light processing has also been used to three-dimensionally print hierarchical zeolite monoliths for nuclear wastewater flow columns, addressing the physical-form constraint that has historically limited powder ion exchangers \[58\].

### 4.5 Stibnite Hill restart, Sanders County, Montana

The restart of Stibnite Hill is the linchpin of the integration thesis. Following Montana state approval, the company began exploration and bulk sampling in 2025, and by August 2026 reported shipping ore by the truckload (an August 2026 disclosure referenced twenty-five additional truckloads of sixteen tons each mined and shipped) \[8\]\[35\]. Management asserts that mining its own material yields profit margins "approximately three times greater than buying from third parties" and that grades are sufficient for a profitable operation \[8\]. These are company statements; no independent, Regulation S-K Subpart 1300-compliant technical report summary establishing tonnage and grade at Stibnite Hill was identified, and the permitting sequence through the Montana Department of Environmental Quality and the Mine Safety and Health Administration is described by the company rather than reconciled to a compliant disclosure.

### 4.6 Alaska land position

Alaska now represents the company's largest exploration footprint but is entirely pre-production. The Ester Dome project (also referenced as Mohawk) comprises four claim blocks exceeding 9,000 acres about seven miles from the Fairbanks airport, with exploration permits received September 22, 2025 and an air-track drilling and trenching program that had evaluated three of fifteen priority targets, with up to fifty holes planned \[35\]. Additional holdings include Stibnite Creek (twenty-four state claims, 3,840 acres, acquired October 2024), the Maclaren River area (sixty-nine claims staked in May 2024), True North (twenty-three claims, 1,349 acres, 2026), Dome Creek Placer (145 patented acres), and Nolan Creek in the Brooks Range \[35\]. Nolan Creek, a known gold-antimony deposit, was acquired through a Trustee's sale on January 30, 2026 \[35\]\[36\]. A qualified report describes an inferred estimate of 42,412 tons grading 28 percent antimony and 0.408 ounces of gold per ton, from which the company derives a gross contained-metal value of roughly $377 million \[36\]. That characterization is internally contradictory as sometimes stated: material classified as inferred cannot be reported as a "reserve" under Regulation S-K Subpart 1300 or under CIM or JORC convention, and the $377 million figure is gross contained-metal arithmetic that excludes recovery, dilution, mining and processing cost, capital, and time, and is therefore not a measure of asset value. No compliant technical report summary reconciling this estimate was identified. A logistics staging and stockpiling center near Fox, Alaska supports these programs, with material intended for trucking to Radersburg \[35\].

### 4.7 Ontario tungsten (Fostung)

The Fostung tungsten property in Ontario is a skarn-hosted scheelite system. An SRK Consulting estimate dated January 2026 reports an inferred mineral resource of 14.77 million tonnes at 0.17 percent tungsten trioxide, containing roughly 54.2 million pounds of tungsten trioxide, with no measured, indicated, or reserve categories and roughly $4 million of further work recommended to reach a preliminary economic assessment \[6\]\[26\]. The company has publicized a "theoretical in-ground value near $9.3 billion," a gross contained-metal figure that carries no economic meaning and should not be read as valuation \[26\]. Fostung is an early-stage diversification option, not a near-term cash contributor.

### 4.8 Bolivia, southeastern United States, and the hydrometallurgical joint venture

The company sources metallic antimony and feedstock internationally, including from Bolivia, Canada, and (per secondary reporting) Chad, and has been described as funding a hydrometallurgical antimony facility in Bolivia \[1\]\[34\]. Announced exploration rights in the southeastern United States align with USGS observations that Mississippi Valley-type lead deposits there may host antimony, but the specific UAMY position is thinly documented in the record reviewed and should be treated as early optionality \[16\]. The most consequential new arrangement is the February 10, 2026 joint venture with **Americas Gold and Silver Corporation (NYSE:USAS)** to build a commercial-scale hydrometallurgical plant in Idaho's Silver Valley adjacent to the Galena Complex, which produced 561,000 pounds of antimony in 2025 \[24\]\[25\]. The venture is owned 51 percent by Americas Gold and Silver and 49 percent by UAMY, with UAMY as managing member and contributor of licensed proprietary hydrometallurgical technology; management envisions a 120,000-square-foot facility producing about 1,000 tons per month of 99.9 percent antimony by 2028 \[24\]\[26\]. That capacity target, if achieved, would dwarf current Thompson Falls output, which is the strongest reason to treat it as aspirational until construction financing and permitting are secured.

### 4.9 The feedstock question

The central operational question is the ratio of purchased third-party ore to company-mined ore. On the evidence, the business remains overwhelmingly a smelter of purchased and byproduct feed: Thompson Falls and Madero have historically run on imported feedstock, Stibnite Hill is at bulk-sampling scale, and every Alaskan property is pre-production \[6\]\[35\]. The company does not disclose a precise blend ratio, and no reliable figure was identified. Management's threefold-margin claim for captive ore is credible in direction (mine margin exceeds purchase margin) but unquantified and unaudited. Until captive tonnage scales, UAMY's earnings are those of a processor exposed to a variable input cost, not an integrated miner capturing a resource margin.

## 5\. Stakeholders and Competitive Landscape

### 5.1 Government stakeholders

The Defense Logistics Agency's Strategic Materials organization is the program manager for the National Defense Stockpile and is UAMY's counterparty on the antimony-ingot supply contract \[3\]. The Department of War's industrial base policy office (Assistant Secretary for Industrial Base Policy) administers the Defense Production Act Title III funds, disbursed through the Defense Industrial Base Consortium managed by Advanced Technology International \[4\]\[5\]. State permitting authorities (the Montana Department of Environmental Quality and Alaska's mining regulators) govern the domestic mining programs, and Mexican federal mining and water authorities govern Madero. The company's positioning is explicitly aligned to Executive Order 14241 of March 20, 2025 on increasing American mineral production \[4\].

### 5.2 Competitors and incumbent capacity

The most advanced Western antimony developer is **Perpetua Resources Corp. (NASDAQ:PPTA**), whose Stibnite Gold Project in Idaho holds an estimated 148 to 149-million-pound antimony reserve (described by USGS as the only company-reported probable antimony reserve in the United States) alongside a 4.8-million-ounce gold reserve \[16\]\[27\]. Perpetua received its Final Record of Decision in January 2025 and its Clean Water Act Section 404 permit in May 2025; on March 31, 2026 the board of the Export-Import Bank unanimously agreed to notify Congress of a proposed $2.7 billion senior secured long-term loan (comprising a direct loan of approximately $2.2 billion with the remainder for capitalized interest and fees), and EXIM's board subsequently gave final approval of a $2.9 billion loan on May 21, 2026 \[27\]\[28\]. The project could meet about 35 percent of US antimony demand in its first six years \[27\]. Perpetua is a mine-first, gold-economics project, structurally distinct from UAMY's processing-first model, but it threatens UAMY's claim to be the essential domestic antimony source.

**Larvotto Resources Ltd (ASX:LRV)** is advancing the Hillgrove antimony-gold project in New South Wales toward production, projected at about 7 percent of global antimony supply \[29\]. UAMY acquired roughly 10 percent of Larvotto on-market and in October 2025 proposed to acquire the remainder at six UAMY shares per 100 Larvotto shares (an implied A$1.40 per share, valuing Larvotto near A$722 million); Larvotto's board rejected the bid as materially undervaluing the company, particularly after UAMY's share-price decline reduced the implied value to about A$1.13 \[29\]\[30\]. The rejected bid is directly relevant to the credibility of the integration strategy: it demonstrates both the company's ambition to secure upstream supply and its inability, so far, to convert that ambition into control, leaving it with a minority financial stake whose mark-to-market swings now flow through UAMY's income statement (a $6.8 million unrealized gain on the Larvotto position was the principal reason UAMY reported positive net income in the second quarter of 2026 despite a $7.0 million operating loss) \[1\].

**Nova Minerals Limited (NASDAQ:NVA)** is advancing the Estelle project in Alaska through its Alaska Range Resources subsidiary, which received a $43.4 million Defense Production Act Title III award in October 2025 to produce antimony trisulfide, a larger Title III award than UAMY's own \[31\]. Americas Gold and Silver, UAMY's joint-venture partner, operates the Galena Complex, the largest current US antimony-producing mine \[25\].

Incumbent non-Chinese processing capacity is more substantial than UAMY's superlatives imply. **Korea Zinc (KRX:010130)** produces antimony ingots at its Onsan smelter at roughly ten tons per day (about 300 tons per month, on the order of 3,500 tons per year), has exported to the United States since 2024 to 2025, and has proposed a multi-billion-dollar critical-minerals smelter in Tennessee that would add antimony among thirteen metals, with phased commercial operation targeted for 2029 \[32\]\[33\]. European processors including **Campine NV** and **AMG Advanced Metallurgical Group** produce antimony chemicals and process recycled feedstock outside China \[34\]. The global cost curve is set by Chinese producers (China produced 40,000 metric tons in 2025, about 36 percent of an estimated 110,000-metric-ton global total, per the USGS Mineral Commodity Summaries 2026) and by Russian and Central Asian producers including Tajikistan; secondary lead smelters supply the recycled fraction \[16\]\[18\]. Against this roster, UAMY's accurate distinction is narrower than "only fully integrated antimony company outside China and Russia": it is better described as the operator of North America's only two long-running primary antimony smelters and the most vertically ambitious North American antimony processor, claims that Korea Zinc's Tennessee plan and Perpetua's mine could erode within the forecast window \[32\]\[33\]\[27\].

## 6\. Economic and Market Dynamics

### 6.1 Reconstructing the antimony price series

Antimony price discovery is opaque and bifurcated, and averaging published series would conceal the most important fact about the market. There is no antimony futures exchange; all price discovery is via assessed physical transactions by reporting agencies, which implies that there is no venue for producers or consumers to hedge, that contracts are struck against assessed benchmarks or negotiated bilaterally, and that "forward" price expectations are analyst opinion rather than market-clearing quotations.

Three benchmarks matter. The Fastmarkets Rotterdam metal assessment (MMTA standard grade II, in-warehouse Rotterdam) rose from about $13,400 per tonne on April 12, 2024 to $22,700 per tonne on June 14, 2024, averaged $22,461 per tonne in July 2024, reached about $32,433 per tonne in October 2024, approached $39,500 to $40,000 per tonne by the end of 2024, and climbed to roughly $57,778 per tonne in April 2025 and $58,000 to $59,650 per tonne in early May 2025 \[9\]\[10\]\[11\]. The USGS, citing Argus, recorded the US metal price (99.65 percent, cost, insurance, and freight) nearly doubling from $8.91 per pound in July 2024 to $17.50 per pound in November 2024, and reported a 2024 annual average of $9.50 per pound versus $5.49 in 2023 \[16\]. The Chinese domestic assessment diverged sharply lower: with exports throttled, Chinese metal remained trapped in the domestic market, and Chinese supplier quotes were reported near $14,000 per tonne while Western spot approached four times that level, a spread that is the single clearest signal of a policy-fractured market rather than a globally cleared one \[11\].

The 2026 direction is downward and is best read through UAMY's own realized prices, because current-year independent assessments were not fully retrievable. The company's average realized antimony selling price fell to $13.70 per pound in the second quarter of 2026 (approximately $30,200 per tonne) from $28.32 per pound a year earlier (approximately $62,400 per tonne), a 52 percent decline, which management attributed to a flood of lower-priced ore into China and generally weaker global prices during the first half of 2026 \[1\]\[22\]. The chief executive publicly anticipated antimony near $10 per pound for the balance of 2026 \[22\].

### 6.2 Unit economics

The second-quarter 2026 disclosures allow a precise read of the model's sensitivity. Antimony pounds sold rose 26 percent year over year to 428,425 pounds, yet antimony revenue fell to $5.9 million because the realized price more than halved \[1\]. The average cost per pound declined 33 percent to $13.34, but the realized price fell 52 percent to $13.70, compressing the antimony gross spread to roughly $0.36 per pound and total company gross margin to 7 percent, from 27 percent a year earlier \[1\]\[22\]. This is the defining datum of the business: as a merchant processor, UAMY's cost per pound (largely purchased feed) fell with the market, but not as fast as its selling price, and the spread it captures is thin and volatile. Volume growth cannot offset price collapse at these margins. In the first quarter of 2026, by contrast, antimony pounds sold had fallen about 23 percent to 278,797 as the company built inventory into a rising cost environment ahead of the smelter commissioning \[2\].

### 6.3 Guidance history as evidence

The fiscal 2026 guidance sequence is a case study in a business model underwritten on peak pricing. In October 2025 management raised full-year 2026 revenue guidance by $25 million to $125 million, citing new Stibnite Hill material and arriving international feedstock \[23\]. It reiterated $125 million at the first-quarter 2026 report in May 2026 \[2\]. On August 11, 2026 it cut the figure to $60 to $75 million, roughly halving the outlook and landing far below the consensus near $115 million, attributing the revision primarily to lower antimony prices, secondarily to the timing of certain DLA deliveries and a slower second-half production cadence \[1\]\[22\]. The revision reveals a forecasting process anchored to a price regime that did not persist and insufficiently hedged against the reversibility of the Chinese restriction that had created it. It should make any reader treat forward company revenue figures as price-contingent management projections rather than as commitments.

### 6.4 Revenue attribution and which projects clear

Two attributions; First, essentially all of UAMY's recognized 2026 revenue to date is merchant-market antimony and zeolite, not DLA revenue: no revenue was recognized under the DLA contract in fiscal 2025, and the first accepted shipments (about 82,000 pounds, roughly $2.6 million) were accepted by the DLA in July 2026 and therefore recognized in the third quarter, not the second \[1\]\[49\]. Second, within the reported segments, zeolite ($1.9 million in the second quarter) and precious-metals recovery are small but stabilizing contributors relative to antimony \[1\].

On the capital-allocation question, at a sustained antimony price near the roughly $10 to $14 per pound management currently anticipates, the arithmetic is unforgiving. With a purchased-feed gross spread of a few tens of cents per pound, the merchant-processing expansion at Thompson Falls clears its hurdle only if captive ore materially lowers input cost or if volumes at the expanded nine-furnace capacity are fully utilized against firm offtake such as the DLA contract. The captive-mining projects (Stibnite Hill, and prospectively Alaska) are the projects most likely to clear, precisely because a mine margin is far larger than a processing margin at depressed prices, which is the economic content of management's threefold-margin claim \[8\]. The 1,000-tons-per-month hydrometallurgical joint venture and the Fostung tungsten option are unlikely to clear conventional hurdle rates at current prices without government capital support, and should be treated as leveraged bets on both higher prices and continued federal subsidy. This is reasoning forward from current margin evidence, not a forecast.

## 7\. Financial Position, Capital Structure, and Government Funding Mechanics

### 7.1 Liquidity, dilution, and cash burn

The company has funded its transformation predominantly with equity, and the dilution has been substantial. Shares outstanding were 119,200,980 as of June 30, 2025 and had risen to roughly 140 million by early 2026, a level at which the market capitalization reached approximately $1.5 billion in April 2026 \[37\]\[38\]. Issuances since 2024 include at-the-market sales (5,652,186 shares through October 9, 2025), warrant exercises (3,493,179 shares), and securities-purchase agreements dated August 26, 2025 (4,000,000 shares) and October 6, 2025 (3,500,000 shares), plus a $25 million securities purchase by a long-only mutual fund in October 2025 \[37\]\[30\]. In the first half of 2026 the company raised $49.1 million net from equity issuances and reported liquidity of roughly $152 million as of March 31, 2026, with working capital doubling to $70 million by June 30, 2026 \[1\]\[51\]. Cash burn was heavy: for the six months ended June 30, 2026, net cash used in operating activities was $20.7 million and in investing activities $11.1 million, against $43.4 million provided by financing; gross capital expenditure was $22.8 million, chiefly Thompson Falls and Radersburg \[1\]. The pattern is clear: the company is funding operating losses and an aggressive capital program by issuing equity into a share price inflated by the critical-minerals narrative, a strategy that works only while that narrative sustains the equity value.

### 7.2 The Defense Logistics Agency contract: ceiling versus realized revenue

The DLA instrument is an indefinite-delivery/quantity sole-source contract announced September 22 to 23, 2025 for antimony metal ingots (99.65 percent purity) to replenish the National Defense Stockpile, with a ceiling of $245 million and a five-year term running through September 2030; the company's fiscal 2025 Form 10-K states the ceiling as $248 million, an increase the filings note but do not fully explain \[3\]\[48\]. The distinction between ceiling, orders, deliveries, and revenue is the single most used figure in commentary on this company, and the layers are as follows. The ceiling is $245 to $248 million and is not a commitment \[3\]\[48\]. Cumulative delivery orders awarded stood at approximately $57.3 million as of the second quarter of 2026 \[1\]. The first delivery order was about $9.9 to $10 million \[1\]. Physical deliveries accepted and invoiced through the report were two June 2026 shipments of about 82,000 pounds, formally accepted by the DLA in July 2026 and recognized as roughly $2.6 million of revenue in the third quarter \[49\]. Shipments five through seven, worth about $3.97 million, were awaiting inspection \[1\]\[49\]. Recognized DLA revenue through June 30, 2026 was therefore zero \[49\]. The gap between a $245 to $248 million headline and zero recognized revenue at the half-year is the essential fact, and pricing on each order is struck at prevailing market rates, so a lower antimony price reduces the revenue that a fixed poundage order generates \[48\].

### 7.3 The Defense Production Act Title III award

The Title III instrument is a $27 million milestone-based, firm-fixed-price award announced March 5, 2026 and obligated February 24, 2026, administered through the Defense Industrial Base Consortium, with a company cost-share of $3.9 million (about 14.4 percent) \[4\]\[5\]. The structure distinguishes obligated from contingent funds: company filings describe roughly $16.2 million of currently obligated funding tied to initial project milestones and about $10.8 million for future phases subject to additional government authorization \[49\]. The company reported achieving $12.8 million of milestones (a portion of the $27 million, not an additional amount) by the first quarter of 2026, allocated roughly $20 million to Thompson Falls and $7 million to Alaska, with the Alaska tranche not expected to be received substantially before 2027 \[2\]\[50\]. The appropriations source is the Additional Ukraine Supplemental Appropriations Act of 2022, and disbursement was delayed by the 43-day federal government shutdown that ended in November 2025 \[4\]\[5\]. The award was one of three Defense Production Act Purchases Office investments totaling $58.5 million since the start of fiscal 2026 \[5\]. Crucially, milestone-based funding can be delayed, reduced, or withdrawn, a risk the shutdown delay already realized in practice.

### 7.4 Pending applications and the shift toward equity

Management has disclosed pending grant applications aggregating roughly $275 million across four applications to the Departments of Energy and War as of the second quarter of 2026, up from about $274 million across three applications at the first quarter, including a formal Department of War application to fund the hydrometallurgical facility \[49\]\[50\]. These are unfunded requests, "never guaranteed" in management's own characterization \[50\]. The broader federal environment has shown a shift toward equity participation over grants in critical-minerals transactions, exemplified by the reported plan for the US government and companies to take a roughly 20 percent stake in the **Korea Zinc** Tennessee joint venture \[33\]. Whether UAMY's pending requests are funded as grants, equity, or not at all is a material swing factor for the capital program.

---

## 8\. Regulatory and Permitting Landscape

The regulatory dimension for UAMY is thinly documented in compliant form, and it is treated here proportionately. Domestic mining at Stibnite Hill and in Alaska proceeds under state permitting (the Montana Department of Environmental Quality; Alaska's mining authorities) with federal Mine Safety and Health Administration oversight of operations; the company describes state approvals for Stibnite Hill and September 2025 exploration permits for Ester Dome but has not reconciled these to a Regulation S-K Subpart 1300 technical report summary for any property \[8\]\[35\]. That disclosure gap is itself the salient regulatory fact: the company reports tonnage and grade estimates (Stibnite Hill, Nolan Creek, Fostung) using terminology that does not conform to the applicable classification standard, and no compliant technical report summary establishing reserves was identified \[36\]\[26\]. Smelter operations at Thompson Falls are subject to federal and Montana air-emissions permitting appropriate to antimony volatilization and smelting, though the record reviewed did not surface a specific enforcement matter. Madero operates under Mexican federal mining and water regulation, a jurisdiction that adds sovereign, water-availability, and community-relations exposure not present at the US sites. The evidence base on the specific permitting timelines for each property is limited, and readers should treat management's permitting representations as company statements pending compliant disclosure.

## 9\. Geopolitical and Strategic Dimensions

### 9.1 The Chinese export-control sequence

The antimony investment case exists because of a specific policy sequence that must be read in order. On August 15, 2024, China's Ministry of Commerce imposed export-licensing requirements on antimony ore, metal, oxides, hydrides, indium antimonides, organo-antimony compounds, and gold-antimony separation technology, effective September 15, 2024 \[12\]\[14\]. Chinese antimony shipments to the United States fell about 97 percent following the controls, and total Chinese antimony exports declined to 38,632 tonnes in 2024, down 24 percent year on year to a five-year low, while global prices for antimony trioxide rose roughly 200 percent \[13\]\[14\]. On December 3, 2024, Ministry of Commerce Announcement No. 46 escalated the licensing regime into an in-principle prohibition on exports of gallium, germanium, antimony, and superhard materials to the United States, and separately prohibited exports of dual-use items to US military end users \[12\]\[13\]. Enforcement extended to a crackdown on antimony smuggling and transshipment through third countries in 2025 \[9\]. Then, following the November 1, 2025 meeting between Presidents Trump and Xi, the Ministry of Commerce announced on November 7, 2025 a suspension of the export prohibition on gallium, germanium, antimony, and superhard materials to the United States until November 27, 2026, reverting to a licensing regime, while retaining the ban on exports to US military end users \[15\].

### 9.2 Quantified effect and the durability question

The measured effects are the roughly 97 percent collapse in Chinese shipments to the United States and the doubling-to-quadrupling of Western prices, with a Western-to-Chinese spread that at its extreme placed Rotterdam metal near $58,000 per tonne against Chinese quotes near $14,000 per tonne \[13\]\[11\]. The United States is 86 percent net import-reliant for antimony (2024, revised, and an estimated 91 percent for 2025), with China historically supplying about 63 percent of combined metal-and-oxide imports over 2020 to 2023, so the exposure was and remains structural \[16\]. UAMY sits within a US critical-minerals policy framework (antimony is on the USGS critical minerals list, the National Defense Stockpile is being replenished, and Executive Order 14241 directs increased domestic production) that has directed real money to the company through the DLA and Title III instruments \[3\]\[4\]\[16\].

The strategic asymmetry is the crux of the risk. A domestic processor that benefits from supply restriction is, by construction, exposed to the reversal of that restriction, and the November 2025 suspension is precisely such a reversal. The 2026 price collapse and the guidance cut are the direct financial expression of that asymmetry: the same policy lever that inflated UAMY's realized price in 2024 to 2025 began to deflate it once China eased. Policy support on the demand side (stockpiling, procurement, subsidy) is more durable than the price support that flowed from restriction, but it is subject to fiscal and political cycles, as the shutdown-driven delay of the Title III disbursement demonstrated \[5\]. The durable case for UAMY is that the United States will pay a strategic premium to maintain domestic capacity regardless of spot price; the fragile case is any thesis that relies on Western prices remaining at 2024 to 2025 peaks.

### 10.1 Interaction among the highest-consequence risks

The correlated risks, not the independent ones, are what threaten the enterprise. Sustained price weakness, Chinese policy reversal, and capital-raising dilution form a single coupled failure mode: the November 2025 easing is a proximate cause of the 2026 price collapse, the price collapse compresses margin and widens operating losses, the losses deepen dependence on equity issuance, and equity issuance depends on a share price that is itself sustained by the critical-minerals narrative that the price collapse undermines. A durable Chinese easing could therefore transmit through price to margin to the equity currency in a self-reinforcing loop. Feedstock economics sit at the center of the defense: captive ore at a threefold margin uplift is the only lever that materially insulates the processor from the price cycle, which is why the pace of Stibnite Hill and Alaska development, and the reliability of the resource estimates underpinning them, are the pivotal variables. Government funding partially decouples the capital program from the equity cycle, but milestone risk and the shutdown precedent show that this decoupling is imperfect. The single most dangerous scenario is a persistent Chinese easing coinciding with a funding reprioritization, which would remove both the price support and the subsidy support simultaneously while the company is still pre-integration.

## 11\. Forward Scenarios to 2030

These are internally consistent reasoning-forward constructions, not forecasts, and each is defined by antimony price regime, degree of vertical integration achieved, and level of sustained federal procurement.

### 11.1 Strategic-premium base case

In this scenario, the Chinese licensing regime after the November 2026 expiry settles into intermittent tightness rather than full prohibition, Western antimony stabilizes in a $15 to $25 per pound band, UAMY brings Stibnite Hill to steady captive production and reaches meaningful utilization of the nine-furnace Thompson Falls capacity, and the DLA contract converts steadily into recognized revenue with periodic new delivery orders. The hydrometallurgical joint venture advances but does not reach its 1,000-tons-per-month target within the window. Revenue recovers toward and beyond the pre-cut $125 million range by 2028 to 2029, with positive gross margin restored by captive-ore economics. The observable confirming indicators are recognized DLA revenue appearing in third-quarter 2026 results and growing thereafter, a disclosed decline in the purchased-to-mined feed ratio, and a Regulation S-K 1300 technical report summary that substantiates Stibnite Hill grades. Falsifying indicators are continued zero or de-minimis captive tonnage and repeated equity raises to fund operating losses.

### 11.2 Commodity-reversion downside

Here China's easing proves durable, Chinese oversupply pushes Western prices back toward $8 to $12 per pound, and merchant-processing margins stay compressed near or below breakeven. Captive-ore development slips on permitting and capital constraints, federal grant applications are only partly funded or are converted to dilutive equity on unfavorable terms, and the share price de-rates as the critical-minerals premium fades, raising the cost of the equity funding on which the company depends. Revenue stagnates near the reduced $60 to $75 million guidance or below, and losses persist. Confirming indicators are a sustained Western-to-Chinese spread compression, a further guidance cut, and dilution at a falling share price. This scenario does not necessarily threaten solvency given low debt and current working capital, but it would invalidate the growth thesis and likely trigger a strategic retrenchment toward the DLA-anchored core plus zeolite.

### 11.3 Integrated national-champion upside

In this scenario, a geopolitical shock (renewed Chinese prohibition, a conflict-driven munitions demand surge, or an explicit US decision to underwrite domestic capacity) restores Western prices above $30 per pound and cements sustained federal procurement, one or more of the pending $275 million applications is funded (as grant or equity), the Larvotto or a comparable upstream acquisition is eventually consummated, and the hydrometallurgical joint venture reaches commercial scale by 2028 to 2029\. UAMY becomes a genuinely integrated, multi-asset antimony and critical-minerals producer with a defensible cost position. Confirming indicators are a funded federal award, a completed upstream acquisition, and construction progress on the Idaho hydromet plant. This is the scenario the current valuation implicitly prices, which is precisely why the gap between it and the base case defines the equity's risk.

## 12\. Strategic Recommendations

### 12.1 Institutional investors and allocators

Treat UAMY as a levered, policy-sensitive option on the antimony price and on US industrial policy, not as an integrated miner, until the feedstock ratio and compliant resource disclosure prove otherwise. Size positions to survive the commodity-reversion downside, and condition any accumulation on specific, observable triggers rather than on narrative: recognized DLA revenue growing across the third and fourth quarters of 2026, a disclosed reduction in the purchased-to-mined feed ratio, a filed Regulation S-K 1300 technical report summary for Stibnite Hill, and evidence that the antimony price has stabilized above roughly $15 per pound. Reduce or avoid on the falsifying signals: another guidance cut, equity issuance at a declining share price to fund operating losses, or a durable Western-to-Chinese spread compression. The Larvotto mark-to-market gain flattering second-quarter net income is a warning to underwrite operating margin, not reported net income, and to discount gross contained-metal "valuations" entirely.

### 12.2 Industrial buyers and defense procurement officers

Qualify UAMY as one of several non-Chinese sources rather than as a sole solution, and structure offtake to reward the strategic capacity. For munitions-primer trisulfide, where substitution is effectively impossible, prioritize dual-qualification of UAMY alongside Perpetua's future output and Nova Minerals' Estelle trisulfide program to avoid single-supplier concentration \[45\]\[31\]. Condition volume commitments on demonstrated, inspected delivery performance under the DLA contract (the July 2026 acceptances are the first real evidence) and on audited capacity utilization at the expanded Thompson Falls smelter. Where security of supply justifies it, offer price floors or take-or-pay terms, because a floor is the single most effective instrument for insulating a strategically necessary but price-exposed processor from the commodity-reversion downside that would otherwise force it to retrench.

### 12.3 Policymakers and critical-minerals program managers

Recognize the structural asymmetry that restriction-driven price support is self-defeating for the domestic producers it is meant to help, and design instruments that survive a Chinese easing. Favor demand-side durability (multi-year National Defense Stockpile procurement at negotiated floors, and equity or milestone structures that fund captive-ore development rather than only processing) over reliance on the price signal, which China controls. The shutdown-driven delay of UAMY's Title III disbursement shows that appropriations-cycle risk is a real impediment; ring-fencing critical-minerals disbursements from continuing-resolution disruptions would materially reduce program risk. Insist on Regulation S-K 1300-compliant resource disclosure as a condition of federal capital, both to protect the taxpayer and to discipline promotional resource claims. Finally, evaluate the domestic antimony portfolio (UAMY's processing, Perpetua's mine, Nova's Alaskan trisulfide, Americas Gold and Silver's Galena feed, and Korea Zinc's allied Tennessee plan) as a system, allocating support to the bottlenecks (defense-grade trisulfide conversion and permitted domestic mining) rather than duplicating processing capacity that the market may not sustain at scale.
