Antimony Resources Faces a Market Squeeze: 21 Million Lock-Up Shares Expire as NI 43-101 Arrives

High-grade antimony intercepts of 36% and 27% at Bald Hill contrast with a 21% stock drop due to a 21M share overhang; a key NI 43-101 resource estimate and US defense demand underpin a CAD 3.00 target.

The Bald Hill antimony project in New Brunswick has delivered some of the highest-grade drill intercepts seen in a primary deposit this cycle, with hole BHW-26-04 returning 36.0% antimony and hole BH-26-15 hitting 27.0%. Yet the company’s stock has shed roughly a fifth of its value over the past month, a slide that reflects a looming overhang of 21 million shares and warrants set to free up on June 29 — the same day the first official NI 43-101 resource estimate lands from SRK Consultants.

That timing is no accident. The lock-up shares were issued at CAD 0.45 in a previous private placement, and with the current market price trading below that level, the potential for selling pressure is real. The relative strength index has dropped to 38.1, deep in oversold territory, and the 30-day decline of about 21% has erased some of the euphoria from a rally that still shows a gain of more than 500% over the past twelve months. The annualised volatility of 100% underlines just how sharp these swings can be.

The resource estimate will be the critical variable. The drilling results from the Main Zone have extended known mineralisation southward across three separate zones at depths around 240 metres, and the conceptual exploration target sits at roughly 2.7 million tonnes grading between 3% and 4% antimony. The current 19,000-metre drill campaign, which runs through the third quarter of 2026, is designed to convert that target into a measured resource. An earlier test interval — almost 15% antimony over three metres — already hinted at the system’s potential.

Geopolitics add a powerful tailwind. China controls half of global mine production and imposed a full export ban on antimony to the United States in December 2024, sending prices to around $60,000 per tonne. While Beijing has since exempted civilian shipments until November 27, 2026, each delivery still requires an individual licence from the central government, and all military end-uses remain prohibited. With no primary antimony currently produced in North America, the provincial government of New Brunswick has designated Bald Hill a strategically important project.

That backdrop has kept analysts bullish despite the near-term price weakness. The consensus target stands at CAD 3.00, driven by the anticipated demand from US defence contractors such as Lockheed Martin, which sits on a multi-billion dollar order book for equipment that relies on antimony-hardened alloys, infrared sensors, and military drone batteries. The stock is trading at EUR 0.39, well below its 50-day moving average and a long way from the 52-week high of EUR 1.05.

The company is not waiting for the resource estimate to advance the permitting front. GEMTEC Consulting Engineers has been engaged to develop a formal permitting roadmap, with a complete application targeted for late 2026 or early 2027. The project sits just 45 kilometres from a deepwater port, offering ready access to export markets. On the financial side, Antimony Resources reported cash reserves of roughly CA$8 million in February, providing a cushion for the ongoing drill programme and preliminary engineering work.

For investors, the June 29 catalyst is a binary event. A resource estimate that confirms the high-grade potential could absorb the selling pressure from the lock-up expiry, while a modest outcome might leave the stock vulnerable to further downside. The market’s attention will also be on the quality of the estimate — whether SRK Consultants can validate the conceptual target and provide a solid foundation for a pre-feasibility study that would solidify Antimony Resources’ role as a prospective North American supplier of a metal the US currently cannot produce domestically.
