Antimony exploration activity in North America continues to accelerate as Antimony Resources Corp announced a significant expansion at its Bald Hill antimony project in New Brunswick, Canada. The company confirmed new discoveries in the Marcus West Zone, including visually identified “massive” stibnite mineralization, reinforcing the project’s growing strategic importance.
Expanded Mineralization Confirmed Through Trenching and Sampling
According to reports from Mining.com, ongoing trenching along strike and systematic sampling have identified additional mineralization hosted within surrounding country rock. Field teams tracked the mineralized structures through continuous surface work, expanding the known footprint of the Marcus West Zone.
Stibnite, the primary ore mineral for antimony, is increasingly critical amid tightening global supply. Antimony is widely used in flame retardants, defense alloys, battery technologies, and semiconductor applications. With supply risks rising, both Canada and the United States are accelerating domestic exploration to secure critical mineral independence.
The latest discovery forms part of Antimony Resources Corp’s 2026 exploration program. In parallel, the company is executing a 10,000-meter drilling campaign at the Main Zone to further delineate high-grade structures and define resource continuity.
Drilling to Accelerate Across Multiple Zones
At Marcus West, drilling is scheduled to commence shortly, with up to six shallow holes targeting mineralization at depths between 30 and 50 meters. The objective is to confirm grade continuity and evaluate near-surface development potential.
In addition to Marcus West and the Main Zone, the company plans to assess underexplored areas, including the Central Zone and South Zone.
Historical trench results from the Central Zone (2010) demonstrated:
-
8.18 meters grading 2.90% Sb
-
Including 1.75 meters at 5.79% Sb
-
And 1.53 meters at 8.47% Sb
Meanwhile, trenching at the South Zone identified stibnite mineralization extending over 150 meters, suggesting strong structural controls and scale potential.
CEO Jim Atkinson expressed optimism about the findings, highlighting the visual confirmation of massive stibnite mineralization collected via excavator sampling. He also confirmed that drilling at the Main Zone is progressing smoothly, with a second drill rig recently mobilized to accelerate the program.
Strategic Importance Amid Global Antimony Supply Tightness
The expansion at Bald Hill comes at a time when global antimony markets face structural supply constraints. As geopolitical uncertainties reshape trade flows and critical mineral strategies, Western governments are prioritizing secure supply chains for defense and high-tech manufacturing.
The discovery of near-surface, high-grade stibnite zones enhances the project’s economic attractiveness, particularly if further drilling confirms lateral continuity and scalable tonnage.
For mining operations transitioning from exploration to development, underground infrastructure and structural stability become critical. As projects move into advanced stages, demand increases for reliable mine support systems, including rock bolts, anchor cables, steel mesh, and steel arches.
Supporting Safe Development of Critical Mineral Projects
As a professional manufacturer and exporter of underground support materials, Hebei Jiufu Industrial and Mining Accessories Co., Ltd. closely follows global critical mineral developments such as the Bald Hill antimony project. With growing exploration and future mine development in North America, demand for high-performance mine support products is expected to rise alongside drilling and underground construction activities.
Reliable ground control systems are essential in structurally complex ore bodies, particularly where vein-style or massive sulfide mineralization is present. Stable excavation conditions directly impact operational safety, development speed, and long-term mine productivity.
Outlook
With expanded mineralization at Marcus West, ongoing drilling at the Main Zone, and evaluation of additional targets, the Bald Hill antimony project is emerging as a strategically significant asset within Canada’s critical minerals landscape.
As exploration intensifies and drilling accelerates, the project’s next phase will likely focus on resource definition and potential development studies. In a tightening global antimony market, scalable and politically stable supply sources such as Bald Hill could play an increasingly vital role.
