The Strategic Clock Ticks for Antimony Supply Beyond China

China's temporary antimony export reprieve until 2026 pressures Western firms to find alternatives. Antimony Resources Corp. aims to develop its Canadian Bald Hill project as a strategic supply source.

A temporary suspension of China's antimony export ban, now set to expire in November 2026, has done little to alleviate long-term supply concerns for Western industries. This brief reprieve has instead created a defined window for companies to secure alternative sources. Antimony Resources Corp. is positioning its flagship Bald Hill project in New Brunswick, Canada, as a potential solution within this critical timeframe.

A Market Under Centralized Control

China's dominance of the antimony supply chain is substantial, accounting for 48% of global production and fulfilling 63% of U.S. import needs. The export system remains tightly regulated; for the 2026–2027 period, authorities in Beijing have approved only eleven companies for antimony exports, maintaining strict state control over volumes and scheduling. Exclusion from this list means no export capability.

This control has direct implications for defense manufacturing. Antimony used in ammunition components must undergo an 18- to 24-month qualification process to meet MIL-SPEC standards. Any entity that begins testing alternative materials only after the suspension lapses in late 2026 faces a significant risk of supply disruption.

Evaluating the Potential of Bald Hill

The Bald Hill asset is a high-grade antimony deposit with a mineralized strike length exceeding 700 meters. A 2025 conceptual target, estimated under NI 43-101 standards, points to 2.7 million tonnes of material grading 3–4% antimony. This range suggests a contained metal content of 80,000 to 106,000 tonnes. It is important to note that these figures have not been formally confirmed by the company.

Antimony Resources has outlined an ambitious 2026 program, including 10,000 meters of drilling and further development of two newly identified zones located south and west of the main area. The company states that financing for ongoing work—encompassing resource estimation, permitting, and a technical gap analysis—is already secured.

Growth Drivers and a Pivotal Milestone

Analysts estimate the current global antimony market at $2.4 to $2.5 billion, with projections suggesting it could expand to between $4.1 and $4.4 billion by 2034/2035. This represents a compound annual growth rate of 5–6%, fueled primarily by defense sector demand and increasing use in high-technology applications.

A key catalyst for Antimony Resources is scheduled for June 2026: the release of Bald Hill’s first official resource estimate. This data will provide a concrete measure of the project's potential to contribute meaningfully to North American antimony supply, testing whether its strategic narrative is supported by substance.
