Antimony Resources Corp. (ATMY) (ATMYF) (K8J0) Reports More Massive Antimony-Bearing Stibnite ("Sb") of 5.10% Sb over 4.0 meters, 2.15% Sb over 6.85 meters and 2.38% Sb over 9.60 meters

Executive Summary

• Antimony Resources released high‑grade antimony assay results from drill holes BH‑25‑22 to BH‑25‑31, confirming continued massive stibnite mineralization across 75‑80% of the holes.
• Notable intercepts include up to 2.38 % Sb over 9.6 m and 6.79 % Sb over 2.3 m, with several zones showing high grade‑thickness values (e.g., 20.4, 15.6).
• The Phase Two program added ~5,000 m of drilling in 2025, bringing total historic drilling to 13,800 m; the Main Zone now extends >700 m laterally and ≥400 m depth, supporting a conceptual resource estimate of 2.7 Mt at 3‑4 % Sb (≈80–106 kt contained antimony).

Key Details

• Assay Highlights
• BH‑25‑22: 5.10 % Sb over 4.00 m (grade‑thickness 20.4) and 2.38 % Sb over 9.60 m (grade‑thickness 22.8).
• BH‑25‑23: 6.62 % Sb over 2.30 m (grade‑thickness 15.2).
• BH‑25‑25: 7.92 % Sb over 0.55 m (grade‑thickness 4.4).
• BH‑26‑26: 2.15 % Sb over 6.85 m (grade‑thickness 14.7).
• BH‑25‑27: 6.79 % Sb over 2.30 m (grade‑thickness 15.6).
• BH‑25‑28: 1.40 % Sb over 7.50 m (grade‑thickness 10.5); 1.91 % Sb over 3.10 m (grade‑thickness 5.9).

• Additional intercepts across holes BH‑25‑29, BH‑25‑31 etc., ranging from 0.14 % to 2.14 % Sb with varying thicknesses.

• Drilling Summary

• Phase Two added ~5,000 m of drilling in fall 2025; total 2025 drilling = >8,000 m across 31 holes.
• Cumulative historic drilling on Bald Hill now exceeds 13,800 m.

• Two planned Phase Two holes were delayed by the Christmas break and will be completed in 2026.

• Geological Interpretation

• Massive stibnite zones with grades up to 30 % Sb observed in core; true thickness estimated at ~75 % of intersected values.
• Main Zone now delineated >700 m strike length, depth confirmed ≥400 m.

• Additional targets identified: South Zone and newly discovered Marcus Zone west of the Main Zone.

• Resource Concept

• NI‑43‑101 technical report (Oct 2025) estimates 2.7 Mt at 3‑4 % Sb, equating to 80,000–106,000 t contained antimony.

• Company notes this estimate is conceptual; further work required to define a mineral resource.

• Quality Assurance / Quality Control

• Samples analyzed by Actlabs (ISO 17025/9001 accredited).

• QA/QC program included certified reference material, duplicates, blanks (~20 % of each batch) and additional instrumental drift checks (~13 %).

• Management Comment

• Jim Atkinson, CEO & President: “Our 2025 exploration program has been very successful… High‑grade antimony values and thick zones will be important factors in the ultimate resource calculation.”
