Antimony Resources Corp. (CSE: ATMY) (OTCQB: ATMYF) (FSE: K8J0) is pleased to announce that it has received assay results from an additional four drill holes in the Main Zone at the Bald Hill Antimony Property. The drill holes are part of the current drill program of approximately 18,000 meters intended to expand the mineralization in the Main Zone and explore the New Zones identified on the property.

Highlights

• High-grade values included 13.14 % Antimony in drill hole BH-26-20 and 16.65% Sb and 33.40 % Sb In drillhole BH-26-25.
• Thickness of these intersected mineralized zones average approximately 4.5 meters with a mineralized zone of 15.9 meters in drill hole BH-26-27.
• Current results include four drill holes which were drilled from the west side into the Main Zone.
• All holes intersected antimony-bearing stibnite.
• The intersections are predominantly at depths of approximately 100 to 150 meters below surface. With one zone at a depth of 260 meters.
• The drill hole intersections often include multiple zones of mineralization. For example, drill hole BHW-26-25 intersected three zones over a drill hole length of over 44 meters

Mr. James Atkinson PGeo, CEO of Antimony Resources commented “These assays from drill holes in the Main Zone continue to return high-grade results. These holes are in the southern part of the Main Zone and were aimed to test the continuity of mineralization in the southern direction and to intersect areas where data is scarce. The focus of this drilling was to infill areas where there were “gaps” in the drilling and assay information. All four of the holes successfully intersected antimony mineralization and effectively detailed the southern part of the Main Zone.

As we have been describing, the current drill program in the Main Zone will be focused on expanding the known mineralization to the south and north and to depth. In addition, drilling will continue to provide information for the modeling of the Main Zone and eventually for the Maiden Resource Estimate.

Meanwhile, exploration in the New Zones is continuing with drilling on the Central Zone ongoing with over 2000 meters completed to intersect below the mineralization exposed in surface trenching (See Press Release Dated June 24^th, 2026) samples from this drilling are currently at the laboratory and results can be expected in approximately two weeks.”

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.

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.
