UNITED STATES ANTIMONY CORP’s Surge and Scaling in U.S. Critical Minerals

Growth Trajectory Fueled by Vertical Integration and Strategic Expansion

Since resuming mining operations in Montana during 2025 after decades of ceasing domestic extraction due to foreign ore competitiveness, UAMY has pursued vertical integration to control its ore supply chain. The purchase of surface rights for patented mining claims enabled mechanized bulk sampling producing about 840 tons of antimony-bearing material at Stibnite Hill [S1]. Concurrently, the Montana processing facility began expanding capacity to more than triple throughput, marking a strategic shift from reliance on imported ores toward an integrated miner-processor model [S1]. This complements broader initiatives since late 2024 acquiring mining claims and leases across Alaska, Montana, Canada, and exploration rights in the southeastern U.S. [S1], aiming to reduce single-source dependence risks.

Mining Rebirth: Reclaiming Domestic Ore Production After Decades

UAMY halted U.S.-based antimony mining activities during the 1980s due to cheaper foreign competition [S1]. Since late 2024 it has reclaimed domestic resource control via acquisitions including a flotation and concentration facility in Radersburg, Montana completed for $4.8 million in January 2026 [S21]. Investments also include workforce housing developments in Thompson Falls critical for labor retention [S1]. Government permits enabled limited surface mining at Alaskan claims before seasonal closure in late 2025 [S1]. While formal mineral reserve classifications are pending, active exploration and surface mining continue establishing resource viability [S1].

New Contracts Bolster Demand but Profitability Pressures Persist

In September 2025, UAMY secured a five-year sole-source Indefinite Delivery Indefinite Quantity (IDIQ) contract with the U.S. Defense Logistics Agency valued up to $248 million for high-purity antimony metal ingots through September 2030 [S26][N2]. Initial delivery orders approximated $12 million by early 2026 though no revenue was recognized in fiscal year 2025 consistent with shipment timing [S26]. Additional commercial contracts include a five-year sales agreement with an industrial customer for antimony trioxide initiated late 2025 [S26].

Revenues surged from $14.9 million in 2024 to $39.3 million in 2025 (+162.8% YoY) primarily due to a near-tripling (+230%) of average sales price per pound amid tight global supply conditions [F1][S27]. Operating income turned more negative at -$8.46 million (-253.8% YoY), reflecting higher operating expenses tied to infrastructure scaling, elevated non-cash share-based compensation after equity incentive plan amendments, personnel hiring costs, and increased professional fees supporting expansion [F1][S12]. These reflect operational scaling challenges absorbing growth investments before realizing scale efficiencies.

Government Funding and Modernization: The $27 Million Title III Award

Supporting growth is a federal commitment under Title III of the Defense Production Act via a $27 million award announced March 5, 2026 by the U.S. Department of War aimed at modernizing domestic antimony production capabilities [S4][S6]. Funding disbursement ties directly to meeting project milestones within plant upgrades primarily at Thompson Falls smelting operations [S6][S21]. This reflects government efforts to reduce import dependence on critical minerals like antimony used extensively in defense applications.

Exploration Ventures: Expanding Claims Across North America

Beyond operational expansions, UAMY's portfolio includes newly acquired mineral claims targeting antimony plus tungsten and cobalt across Alaska, eastern Canada, and southeastern United States [S1][S7]. While economic reserves are not yet established — typical at early exploration stages — ongoing assay testing and limited surface mining demonstrate progressive maturation [S1]. These initiatives aim both to diversify raw material feedstock and position for future critical mineral demand amid evolving global supply dynamics.

Capital Allocation: Equity Raises, Capex Surge, and Capital Structure

Growth plans relied heavily on equity issuance during fiscal year 2025 raising net proceeds around $110 million via multiple "at-the-market" offerings and registered direct offerings with institutional investors plus warrant exercises [F1][S4][S14][S25]. This funded an unprecedented capex surge (+6358% YoY) totaling $27.8 million focused on expanding smelting capacity ($17.5 million), acquiring new mining properties such as Fostung tungsten claims ($5 million), logistical assets including employee housing ($5.7 million), and purchasing strategic processing facilities like Radersburg flotation plant ($4.8 million) [F1][S8][S21].

Operating cash flow showed net outflows near -$9.7 million driven mainly by working capital buildouts including inventory increases over $12 million largely from antimony oxide stockpiling ahead of demand fulfillment [F1][S22]. Financing activities offset these outflows with net inflows exceeding $109 million primarily from equity issuances [F1][S22]. Liquidity remains strong with cash & equivalents around $30.5 million plus undrawn margin credit lines collateralized by Treasury Strip investments over $20 million supporting operational flexibility [F1][S4][S14].

The company did not pay dividends recently preserving cash for reinvestment but executed minor share repurchases (~$449k) mostly related to employee stock award settlements during fiscal year 2025 [F1][S11][S25].

Financial Performance Snapshot: Revenue Spikes Amid Operating Challenges

Contract-backed demand growth combined with elevated antimony prices drove revenues above historical levels — exceeding $39 million in fiscal year 2025 versus under $15 million the prior year representing nearly triple top-line growth [F1]. However operating losses deepened due to staffing expansions coupled with maintenance costs plus non-cash equity compensation charges escalating after incentive plan amendments late-2023 [F1][S12], suppressing net income into negative territory (-$4.34m). Estimated return on equity stands near negative three percent reflecting transitional investment stages outpacing near-term profitability gains.

Negative free cash flow—operating cash outflows combined with elevated capex spending (~$37m)—illustrates capital intensity inherent in scaling expanded mining operations and modernized processing facilities essential for fulfilling long-term contracts effectively [F1].

What to Watch: Operational Scaling and Market Dynamics

Key indicators during calendar year 2026 include completion timelines for smelter capacity expansions underway post-March NYSE listing critical for meeting delivery volumes under government contracts secured starting September prior year [N2][S3][S21]. Ore assay results from new North American claims will influence feedstock quality mix impacting process efficiency metrics while global antimony price volatility could compress margins if prices decline or supply-demand shifts impact contract pricing formulas embedded within IDIQ agreements.

Government milestone payments tied directly to Title III modernization awards provide partial visibility into funding cadence; however continued cost pressures warrant close monitoring alongside incremental contract fulfillment revenue streams.
