Antimony Resources Corp. (ATMY) (ATMYF) (K8J0) Reports High-Grade Antimony (Sb) Assays - Drills 27.3% Sb Over 0.3 Meters (m) Within a Zone of 2.28% Sb Over a Length of 9.12 m

Antimony Resources Corp. (CSE: ATMY) (OTCQB: ATMYF) (FSE: K8J0) (the "Company" or "Antimony Resources" or "ATMY") is pleased to announce that it has received assays from drill holes in the Main and Central Zones at the Bald Hill Antimony Project in New Brunswick. The drill holes are part of the current drill program intended to expand the mineralization in the Main Zone and fill-in gaps in the data. Drill results Main Zone Drilling continued in the Main Zone with drill holes BH-26-19 and BH-26-21 returning high-grade antimony values. We note the high-grade antimony in BH-26-21 with a grade of 27.3 % Sb over 0.3 meters (m) within a zone of 2.28% Sb over a length of 9.12 m from 144.38 to 153.5 m depth . The corresponding gold assay is 0.93 g/t over the same width with a high of 3.66 g/t.

Note that these are intersected widths, and the true widths are estimated to be about 70% to 80% of these lengths.

Central Zone Drilling is being completed on the newly identified Central zone where trenching by ATMY and previous operators has identified antimony-bearing stibnite mineralization. This zone had not been drilling in the past and our current program will be a preliminary test of the mineralization below the surface trenches.

Press Release dated July 27, 2026, detailed the geological descriptions of the first 8 drillholes into the Central Zone. Results from the BHC-26-01, from the Central Zone are reported in Table below . Drill Hole BHC-26-01 returned a high-grade assay of 10.3% Sb in a section of 2.63% Sb over 2.2 meters from 118.8 to 121.0 depth. This hole is focused on intersecting below the northernmost trench of the Central Zone.
