Antimony Resources Corp. (ATMY) (ATMYF) (K8J0) Discovers Extension of the Massive Antimony-Bearing Stibnite Mineralization at the Marcus (West) Zone

Executive Summary

• Antimony Resources reports continued surface exposure of massive antimony‑bearing stibnite mineralization in the newly discovered Marcus (West) Zone at Bald Hill, New Brunswick.
• Trenching 30 m south of the original “Discovery Boulder” extended visible mineralization to ~80 m and confirmed stibnite grades comparable to the Main Zone.
• To date, 6,500 m of a planned 10,000‑m definition drilling program have been completed across the Bald Hill project, with ongoing drilling on both East and West portions of the Main Zone and future trenching slated for the Central Area.

Key Details

• Trenching Results:
• Trench located ~30 m south of the February 17 “Discovery Boulder” intersected massive stibnite in bedrock.

• Surface exposure now spans approximately 80 m, with mineralization resembling that of the Main Zone (high‑grade antimony).

• Definition Drilling Progress:

• Total of 6,500 m drilled out of a 10,000 m program completed to date.

• Drilling continues from both East and West rigs targeting antimony‑bearing stibnite intersections in the Main Zone.

• Future Exploration Plans:

• Continued trenching and sampling in the Marcus (West) Zone through winter months.
• Upcoming focus on the Central Area, where historic assays showed 2.8 % antimony over 8 m.

• Drilling to follow trenching/sampling in the Central Zone.

• Project Context:

• Bald Hill Antimony Project hosts a known high‑grade deposit; Main Zone mineralization averages 3–4 % antimony over widths of 3–4 m, extending >700 m laterally and ≥350 m deep.

• NI‑43‑101 technical report (2025) estimates ~2.7 Mt at 3–4 % antimony for the Main Zone target area (conceptual, not a defined resource).

• Management Comment:

• CEO Jim Atkinson highlighted the successful winter field work and emphasized the Marcus (West) Zone as a “significant addition” to project potential.
