Behind the 600% Rally: Antimony Resources’ Upcoming Resource Estimate Could Validate the Hype

China dominates global antimony supply; Antimony Resources Corp. nears resource estimate for Bald Hill, with high-grade results and up to 92% recovery from waste rock, as geopolitical demand surges.

The global antimony market is braced for a supply squeeze. China churned out roughly 40,000 tonnes of the critical mineral in 2025 — a dominant share of the 110,000?tonne total — while the rest of the world scrambles for alternative sources. Antimony Resources Corp. is positioning itself as a potential answer, and the next few weeks will test whether its flagship Bald Hill project in New Brunswick can deliver.

The company expects to release its first formal resource estimate by the end of June. SRK Consultants of Toronto, a firm with specialised experience in antimony deposits, is preparing the NI 43?101?compliant calculation. The conceptual target stands at roughly 2.7 million tonnes grading between 3 and 4 percent antimony, with mineralization traced over 700 metres of strike and to a depth of 350 metres — and open in all directions.

Crucially, metallurgical work has shown that up to 92 percent of the antimony can be recovered directly from existing waste rock piles, significantly lowering early?stage development costs.

A 19,000?metre drilling programme is already turning. The campaign, launched in early May, includes 13,000 metres of expansion drilling in the Main Zone and 6,000 metres of first?pass drilling across three newly defined targets. Among them, the Marcus West Zone boasts stibnite outcrops up to 11 metres wide, and the BH South Zone returned assay results of 9.04 percent antimony over 2.6 metres and 12.32 percent over 1.7 metres. About three kilometres south of the main deposit, more than 550 soil samples identified three anomalous areas with antimony concentrations five to forty times above natural background, peaking at 453 ppm. The company has already staked additional claims to the west.

The geopolitical backdrop amplifies the project’s rationale. Both the United States and the European Union have listed antimony as a critical mineral; the US Permitting Council calls it essential for defence equipment and energy technology. Fortune Business Insights projects the global antimony market will grow from $1.22 billion in 2026 to over $2 billion by 2034.

Permitting is advancing in parallel. Since April, GEMTEC Consulting Engineers has been working on a full regulatory roadmap, with an environmental impact assessment submission planned for late 2026 or early 2027. New Brunswick has promised expedited permitting for critical minerals.

The stock reflects both the opportunity and the uncertainty. Trading at €0.51, it sits roughly 52 percent below its March high of €1.05, yet it has still gained more than 600 percent over the past twelve months. With a 30?day annualised volatility of 136 percent, the shares remain firmly in speculative territory. The resource estimate due by the end of June will determine whether the conceptual target holds substance — and whether the 600% rally has further to run.
