Antimony extends stibnite mineralization at Bald Hill

Executive Summary

• Antimony Resources Corp. has confirmed an extension of massive antimony-bearing stibnite mineralization at the newly discovered Marcus (West) zone on its Bald Hill project in New Brunswick, Canada.
• Trenching approximately 30 meters south of the initial discovery boulder has exposed continuous mineralization over an 80-meter stretch, with grades and geological characteristics closely resembling the high-grade Main zone.
• The company is actively advancing its 10,000-meter definition drilling program, having completed 6,500 meters to date, with ongoing exploration on the Main and Marcus (West) zones and planned follow-up trenching and drilling in the Central area.

Key Details

• Marcus (West) Zone Trenching: Trenching ~30m south of the initial discovery boulder exposed massive stibnite in bedrock, extending surface mineralization exposure to ~80 meters. Washing and sampling continue in this area.
• Mineralization Characteristics: Samples display massive stibnite mineralization with concentrations and geological descriptions matching the high-grade Main zone.
• Drilling Progress & Scope: 6,500 meters of the planned 10,000-meter definition drilling program completed. Two drill rigs are actively drilling the Main zone from both east and west, intersecting antimony-bearing stibnite.
• Main Zone Project Metrics: Drilling has outlined the Main zone over 700 meters long and to a depth of at least 350 meters, open in all directions. Average mineralization widths are 3–4 meters, with grades averaging 3–4% antimony.
• NI 43-101 Technical Report (2025): Estimates potential of ~2.7 million tonnes at 3–4% antimony in the drilled area. Note: This is conceptual; insufficient exploration exists to define a mineral resource, and further work is required to delineate it.
• Future Exploration Plans: Trenching and sampling will shift to the Central area (south of the Main zone), where past exploration identified 2.8% antimony over 8 meters. Drilling will follow trenching in this target.
• Property Expansion: Potential exists to expand the project based on recently discovered targets and additional claims added to the west, south, and east of the property.

Notable Quotes

• Jim Atkinson, PGeo, CEO: "The Marcus (West) zone is shaping up to be a significant addition to the potential of the Bald Hill antimony project. Their next area of focus will be the recently reidentified Central zone to the south of the Main zone, where 2.8 per cent antimony over eight metres was described in past trenching."
• Jim Atkinson, PGeo, CEO: "Drilling on the Main zone continues with two drill rigs focused on this area. They have reached a total of approximately 6,500 metres of our proposed 10,000 metres of definition drilling."
