Antimony finds new stibnite mineralization at Marcus

Executive Summary

• Antimony Resources Corp. has discovered and exposed new massive stibnite mineralization at the Marcus (West) zone over a 25-meter distance in bedrock, interpreted as a separate zone from the main Bald Hill deposit.
• A 2026 definition drilling program has commenced at the Bald Hill main zone using two drill rigs (with a third added in early February) to delineate mineralization over a 600-meter strike length and 300-meter depth, targeting data sufficient for a maiden resource calculation.
• The company plans additional trenching and sampling for the 2026 exploration season at both the newly discovered Marcus (West) zone and the Bald Hill south zone, which has already yielded 150 meters of stibnite-bearing outcrop and boulders.

Key Details

• Marcus (West) Zone Discovery: New massive stibnite mineralization exposed in bedrock over a 25-meter distance; considered separate from the main zone.
• Drilling Accessibility: New discovery can be tested via shallow drilling from existing locations (BHW26-01 to BHW26-04) by simply turning the drill 180 degrees.
• 2026 Definition Drilling: Commenced at Bald Hill main zone with two rigs; third rig added early February.
• Drilling Scope: Focused on detailed sampling over a 600-meter distance to a minimum depth of 300 meters to support consultant-led maiden resource calculation.
• 2026 Exploration Plans: Additional trenching and sampling scheduled for the newly discovered Marcus (West) zone and the Bald Hill south mineralization.
• Bald Hill South Zone: Trenching identified stibnite-bearing boulders and outcrop over a 150-meter distance.
• Bald Hill Project Highlights: High-grade antimony deposit in southern New Brunswick, Canada; drilling has outlined mineralization over 700 meters long; average widths of 3 to 4 meters; average grades of 3% to 4% antimony.
• NI 43-101 Technical Report (Oct 28, 2025): Estimates potential of approximately 2.7 million tonnes at 3% to 4% antimony; noted as conceptual in nature pending sufficient exploration to define a mineral resource.
