Antimony Resources drills 27.3% Sb over 0.3 m within 2.28% Sb over 9.12 m

Vancouver, British Columbia--(Newsfile Corp. - September 11, 2026) - 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 holes in the Central Zone are the first in this series yet to be reported.

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.

Figure 1 below shows the distribution of drill holes in the Main Zone and the extent of the surface projection of mineralization. The zone is open to the north and south

Central Zone

Drilling is being completed on the newly identified Central zone where trenching by ATMY and previous operators has identified antimony-bearing stibnite mine
