Antimony Resources Faces a June Junction: Lock-Up Expiry Meets Resource Estimate Amid Structural Supply Squeeze

Antimony Resources is barreling toward a pair of events in late June that will test whether the company’s macro bull case can withstand near-term selling pressure. An estimated 21 million shares from a December placement become freely tradable around the same time the consultancy SRK is due to deliver an official resource estimate for the Bald Hill project. The timing has traders weighing the prospect of profit-taking against the kind of catalyst that can underpin a valuation.

The lock-up expiration hits a stock that has already been through a wringer. From a March high of 1.65 Canadian dollars (around 1.05 euros), the shares have plunged more than 50%. Over the past 30 days alone the decline reached roughly 30%, though a 24% bounce in the last week suggests some dip-buying has emerged. The placement participants paid 0.45 Canadian dollars per unit, a steep discount to the current price of 0.76 dollars, and each unit came with a warrant exercisable at 0.75 dollars. That means the early backers are sitting on a paper gain of nearly 70%, and the market will be watching closely to see whether they book profits or hold for the longer story.

That story hinges on a global antimony supply chain that China has fundamentally disrupted. Beijing’s export ban on the metal, imposed in late 2024, cut off the vast majority of supply to North America. China controls roughly 85% of world production, and antimony is classified by the US Geological Survey as critical for lead-antimony alloys used in ammunition and defense. A temporary diplomatic thaw has since eased some restrictions, but the suspension of China’s export controls on strategic metals is set to expire in November 2026 – a date the company sees as an explicit countdown.

What is less understood is that the bottleneck is not just in mining but in processing. The United States Antimony Corporation operates the only meaningful antimony smelter in the country, located in Thompson Falls, Montana. Built in 1969, it is currently sold out and undergoing an expansion from 100 to more than 500 tonnes per month. Even after that upgrade, the gap between North American smelting capacity and demand remains enormous, and the US national defense stockpile is shrinking rapidly. Canada, which classifies antimony as a critical mineral, produces only about 200 tonnes per year – a fraction of what the region once imported from China.

Should investors sell immediately? Or is it worth buying Antimony Resources?

Bald Hill, located in New Brunswick, is positioned not as an isolated mine but as a potential feedstock supplier for an underfed processing network. The company has begun its next exploration phase, drilling in the main zone and three newly discovered mineralized zones across a land package that now covers 37 square kilometers. A recent trenching program in the South zone returned an average antimony grade of 19.5%, with intervals exceeding 44%. CEO Jim Atkinson has stressed that there is currently no primary antimony producer in North America, meaning any successful development would fill a structural void.

Yet the share price has been battered by a broader commodity market headwind. Antimony prices have fallen 36% since their summer 2025 peak and now hover around $35 per kilogram, pressured by new supply offers and substitution efforts. The stock’s 50-day moving average of 0.60 euros sits about 20% above the current level, while the 200-day average at 0.45 euros provides nearby support. With an RSI of 47.2 and 30-day annualized volatility near 143%, the technical picture is neutral but precarious.

The resource estimate due by end of June could shift the narrative. SRK has been conducting a technical gap analysis to identify risks in timeline, permitting and economic viability. Management is targeting a formal permit submission in Q4 2026, with a planned flotation mill to produce high-grade concentrate directly for smelters. A strong resource number would reinforce the argument that Bald Hill can actually deliver, and it might absorb any selling pressure from the expiring lock-up by giving new buyers a reason to step in.

Antimony Resources at a turning point? This analysis reveals what investors need to know now.

For now, the stock is caught between a macro thesis that is unusually clear – a defense-critical metal, Chinese dominance, an expiring moratorium, and an almost empty Western project pipeline – and the micro reality of a junior explorer that must prove it can execute. The next two weeks will show whether the market sees the SRK report as a catalyst or a cover for early investors to exit.
