UAMY Soars 11.16% on Stibnite Mine Restart, $125M Revenue Hike, Acquisition Push

United States Antimony Corporation (NYSE: UAMY) surged 11.16% in pre-market trading on November 7, 2025, driven by a series of strategic moves and market dynamics. The stock’s sharp rise followed the company’s announcement to restart operations at the Stibnite Hill mine in Montana using advanced techniques to boost margins and raise 2026 revenue guidance to $125 million. Additionally, UAMY proposed acquiring Larvotto Resources, a move aimed at expanding its antimony resource footprint beyond China and enhancing geopolitical resilience. A $25 million registered public offering further underscored the firm’s commitment to scaling smelting capacity and pursuing strategic acquisitions.

The stock’s momentum aligns with broader industry tailwinds, including rising antimony prices and heightened demand for specialty materials in national security applications. William Blair’s recent initiation of coverage with an “Outperform” rating amplified investor confidence, highlighting UAMY’s unique positioning in a resource-critical sector. Despite mixed financial metrics—such as a 25.9% gross margin against a -3.9% EBT margin—the company’s focus on operational efficiency and debt management (debt-to-equity ratio of 0.03) suggests a disciplined capital structure.

Analysts note that UAMY’s aggressive expansion strategy, including the Stibnite Hill project and cross-border acquisitions, could unlock long-term value. However, risks remain tied to execution timelines and market volatility. The stock’s pre-market surge reflects optimism around these catalysts, though traders are advised to monitor cash flow dynamics and regulatory progress for Stibnite Hill permits.

A hypothetical backtest scenario using UAMY’s recent price action and strategic announcements suggests a potential long-bias strategy. Traders might consider entering positions on breakouts above key resistance levels, supported by RSI divergence and MACD crossovers. Stop-loss placement near 200-day moving average levels could mitigate downside risk, while profit targets align with the $125 million revenue guidance’s implied valuation multiples. This approach balances momentum trading with fundamental catalysts, reflecting the stock’s high volatility and event-driven nature.
