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. 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. The company notes the high-grade antimony in BH-26-21 with a grade of 27.3 per cent antimony (Sb) over 0.3 metre (m) within a zone of 2.28 per cent Sb over a length of 9.12 m from 144.38 to 153.5 m depth. The corresponding gold assay is 0.93 gram per tonne (g/t) over the same width, with a high of 3.66 g/t.

Central zone

Drilling is being completed on the newly identified central zone, where trenching by the company and previous operators has identified antimony-bearing stibnite mineralization. (See the news release dated June 25, 2026. This zone had not been drilling in the past and the company's current program will be a preliminary test of the mineralization below the surface trenches.)

The news release dated July 27, 2026, detailed the geological descriptions of the eight drill holes into the central zone.

Results from the BHC-26-01, from the central zone, are reported in an attached table.

Drill hole BHC-26-01 returned a high-grade assay of 10.3 per cent Sb in a section of 2.63 per cent Sb over 2.2 m from 118.8 to 121.0 m depth. This hole is focused on intersecting below the northernmost trench of the central zone.

James Atkinson, PGeo, chief executive officer of Antimony Resources, commented:

"We are containing to receive high-grade antimony results from the main zone. The drilling has been focusing on infilling gaps in the data by intersecting areas where there was little or no drill information to attempt to develop a more detailed picture of the deposit. This new information has been incorporated into an updated mineral model, which will be used to focus further drilling. We are very pleased with the first set of assays from the central zone. The surface trenching and sampling exposed antimony mineralization in the form of stibnite in trenches over a 200-metre length in the central zone. Drill hole BHC-25-01 confirms the antimony-bearing stibnite at a depth of 100 meters. As we have been describing, the central, south and Marcus zones hold promise to develop into additional areas of antimony mineralization on the larger Bald Hill property.

QA/QC (quality assurance/quality control)

Samples from the drilling rigs are transported to the company's secure core handling facility, where they are examined by the company's 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 the company's professional geological staff. The marked core for sampling is cut by diamond saw, 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, Ont. The samples are analyzed using Actlabs method code 1E3, aqua regia, ICP-OES (inductively coupled plasma optical emission spectrometry) for the multielement, and code 1A2, fire assay, atomic absorption 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.

Bald Hill antimony project -- a project with significant antimony potential

Highlights:

• Bald Hill is a high-grade antimony deposit in southern New Brunswick, Canada;
• Assays indicate that Bald Hill is the highest-grade antimony deposit in North America, with minable grades and widths indicated by drilling;
• Drilling has outlined an antimony deposit in the main zone over 600 m long and to a depth of at least 350 m. The mineralization is open in all directions;
• Widths of mineralization average four to five m and grades average 3 per cent to 4 per cent antimony;
• National Instrument 43-101 technical report: The estimated potential quantity and grade of the drilled area from the 2025 technical report, which is the target of the company's exploration, are reported in the technical reports approximately 2.7 million tonnes with a grade between 3 per cent and 4 per cent antimony (1). For more details on the potential of the project as described by the author of the technical report, please consult the NI 43-101 report, which has been filed on SEDAR+. Antimony Resources 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 three kilometres south of the main zone on the newly acquired Second Run claim.
