Antimony Resources Corp. (CSE: ATMY) (OTCQB: ATMYF) (FSE: K8J0) is pleased to announce that it has received assay results from an additional drill hole in the Main Zone at Bald Hill. The drill hole is part of the current drill program intended to expand the mineralization in the Main Zone.

Drilling on the recently identified Central Zone has identified zones of stibnite mineralization. Geological descriptions from six drill holes have been received and are reported in this Press Release.

Highlights

• High-grade values included 11.41 % Antimony (Sb) over 1.55 meters (m) in drill hole BH-26-14 in the Main Zone.
• Mineralization in this hole averages 2.78 % Sb over 11.3 meters.
• Gold is seen associated with the Stibnite mineralization and averages 0.41gram per tonne (g/t) Au over the same 11.3 meters with sections over 1 g/t Au.
• Drill holes completed into the Central Zone intersected antimony-bearing stibnite below surface trenches with antimony-bearing stibnite.
• Descriptions of drill core from the Central Zone identify breccia containing breccia with stibnite in 6 drill holes.
• The intersections are predominantly at depths of approximately 100 to 150 meters below surface.
• The drill hole intersections include multiple zones of mineralization. For example, drill hole BHC-26-03 intersected three zones of stibnite -bearing breccia over a drill hole length of approximately 35 meters

Main Zone

Drilling continued in the Main Zone with drill hole BH-26-14 returning high-grade antimony values in two separate zones at depths of 130 and 165 meters. The higher-grade interval of 11.41% Sb from a depth of 132.0 m to 133.55m is within a much wider zone of 11.30 meters. grading 2.78 % Sb.

A second mineralized zone is seen from 165.35m to 168.0 m which returned 7.48% Sb.

Central Zone

Drilling which has been completed on the newly identified Central zone where trenching by ATMY and previous operators has identified antimony-bearing stibnite mineralization. (see Press Release Dated June 24, 2026 which reported 38 rock samples averaging over 19% Sb). This zone had not been drilled in the past and our current program will be a preliminary test of the mineralization below the surface trenches.

Below are geological descriptions of the first six drill holes at the Bald Hill Central Zone.

Note that assays have not been received for these holes and the descriptions are based on visual geological observations only. Once assays are received, these intersections can be fully evaluated. The important observation is that the drill holes have intersected breccia zones like other mineralized sections in the Main Zone and in surface in Trenches.

QA/QC

Samples from the drilling rigs are transported to our secure Core Handling Facility where they are examined by our geotechnical staff. Once the information on core conditions including RQD, lost core etc.are recorded and the core is confirmed to be intact and orderly it is logged and marked for sampling by our professional geological staff. The marked core for sampling is cut by diamond say one half is returned to the box for safekeeping, and one half is placed in plastic bags. The bags are sealed and placed in larger canvas bags for shipment to the Activation Labs Processing facility in Fredericton where they are crushed and prepared for shipment to the assay lab in Ancaster Ontario. The samples are analyzed using Actlabs Method Code 1E3 Aqua Regia ICPOES for the multi element and Code 1A2 Fire Assay AA for gold.

Quality Assurance and Quality Control samples are inserted in the sample runs which include a known standard for antimony and gold, a core duplicate, a blank, and a pulp duplicate. Activation Labs also has standard QA/QC protocols which are reported with each assay batch. Activation Laboratories in an internationally accredited assay Laboratory.

Mr. James Atkinson PGeo, CEO of Antimony Resources commented “We have been aggressively exploring the newly identified Central Zone at Bald Hill. To date 15 drillholes have been completed and core logging has been completed on six of the drillholes. This is one of the “New Zones” which has been identified on the Bald Hill Project. The Central Zone is approximately 200 meters south of the southern extent of the Main Zine, however, drilling is attempting to demonstrate that the Central and Main Zones could form a continuous deposit. Descriptions of the core from the Central Zone drilling identifies areas of visible stibnite mineralization in a breccia zone. This style of mineralization is similar to the Main Zone. Meanwhile the drilling on the Mine Zone has been focused on in-filling gaps in the mineralization in order to develop a detailed picture of the deposit”

Bald Hill Antimony Project – A Project with Significant Antimony Potential

Highlights

• Bald Hill is a well-known, high-grade antimony deposit in southern New Brunswick, Canada.
• Assays indicate that Bald Hill is the highest-grade antimony deposit in North America with mineable widths indicated by drilling.
• Drilling has outlined an antimony deposit in the Main Zone over 600 meters long and to a depth of at least 350 meters. The mineralization is open in all directions.
• Widths of mineralization average 4 to 5 meters and grades average 3% to 4% antimony.
• NI-43-101 Technical Report: The estimated potential quantity and grade of the drilled area from the 2025 Technical Report, which is the target of our exploration, is reported in the Technical Reports approximately 2.7 million tonnes with a grade between 3% and 4% antimony¹. For more details on the Potential of the project as described by the author of the Technical Report please consult the NI43-101 which has been filed on SEDAR+. Antimony Resources Corp. has not completed enough work to confirm this estimate. The potential quantity and grade are conceptual in nature as there has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the target being delineated as a mineral resource.
• Potential to expand based on recently discovered targets and additional claims added to the property to the west, south and east.
• New Zones outlined by Soil Sampling approximately 3 kilometres south of the Main Zone on the newly acquired Second Run Claim.
