Antimony Resources Nears Key Milestone with Upcoming Resource Estimate

Antimony Resources advances as US defense spending and solar sector demand create a strong structural backdrop. Its Bald Hill project nears drilling completion, targeting a high-grade resource estimate in June.

A combination of Chinese export controls on antimony and a proposed US defense budget of $839 billion for 2026 is creating a powerful structural demand backdrop, providing favorable conditions for North American exploration companies. Antimony Resources stands to benefit from this environment, with its shares advancing approximately 6 percent today to CAD $1.40.

Strategic Demand Drivers: Defense and Solar Applications

The fundamental case for antimony remains robust, underpinned by critical applications in two major sectors. For the US defense industry, the metal is essential both as a hardening agent in lead alloys for ammunition and as a component in fuse mechanisms. The US Defense Logistics Agency classifies antimony as a priority material, and the 2026 defense budget alone allocates $12 billion for strategic mineral stockpiles.

In the renewable energy sector, First Solar continues to require sodium antimonate as a fining agent for high-transmission photovoltaic glass, despite its independence from Chinese silicon supply chains. The company recently issued 2026 revenue guidance of $4.9 to $5.2 billion, which disappointed the market and triggered a share price decline of roughly 13 percent. This reaction underscores the sector's acute sensitivity to any perceived supply chain vulnerabilities.

Bald Hill Project Progress: Drilling Nears Completion

The company's flagship Bald Hill project, located in New Brunswick, Canada, is rapidly advancing. A definition drilling program targeting the Main Zone is well underway, with 6,500 meters of the planned 10,000-meter campaign already completed. Drilling from both eastern and western directions has consistently intersected stibnite mineralization containing antimony, corroborating the known strike length of 700 meters.

The remaining drilling is scheduled for completion by the end of April. Final assay results from the mineralized samples are anticipated three to four weeks thereafter. This sets the stage for an initial mineral resource estimate in June. The company is being assisted by Toronto-based SRK Consultants, which previously completed a resource calculation for the former Beaverbrook production project in Newfoundland.

Project Expansion with New Discovery

Exploration success is extending beyond the Main Zone. Work on the newly identified Marcus (West) Zone has progressed through winter trenching, which expanded the massive stibnite mineralization to approximately 80 meters. This extension runs from a discovered boulder to an outcrop in bedrock about 30 meters to the south.

Attention will subsequently turn to the Central Area. Historical exploration data from this zone indicates a grade of 2.8 percent antimony over 8 meters, though a systematic investigation by the current technical team has yet to be conducted.

Catalyst Ahead: The First Formal Resource Estimate

According to a technical report, Bald Hill is considered one of the highest-grade antimony deposits in the Western world, with an estimated 2.7 million tonnes of ore grading between 3.0 and 4.0 percent antimony. The publication of a maiden NI 43-101 compliant resource estimate in June represents a pivotal catalyst. This event would transition the project from a conceptual target to a formally quantified asset—a milestone that typically attracts heightened interest from institutional investors in the junior exploration space.
