Antimony Resources Corp. (CSE: ATMY) (OTCQB: ATMYF) (FSE: K8J0) is pleased to announce that it has received additional assay results from four drill hole in the Main Zone at Bald Hill. 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.

Drilling Results

Main Zone

Drilling continued in the Main Zone with drill holes BH-26-07,16 and 18 returning high-grade antimony values. BH-206 did not intersect mineralization. We note the high-grade antimony in BH-26-16 of 13.0% Sb from 305.8 to 307.9 and the corresponding high-grade gold of 2.2 g/t over the same width. The full width of this zone of 3.29 meters had corresponding high-grade antimony and gold results.

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

The extreme curvature of BH-26-06 caused the hole to miss the Mineralized Zone and resulted in no significant assays in the drillhole.

The company is also pleased to describe the importance and use of Artificial Intelligence (AI) and Drone Technology in the exploration and development of the Bald Hill Antimony Deposit.

The Use of Artificial intelligence

AI empowers our team to accomplish more with greater accuracy, and that lets them spend more of their time exploring and proving the resource potential at Bald Hill.

• We’re not trying to replace people with technology. We’re trying to stop our exploration teams from spending their valuable time on data entry resulting in more “Boots on the Ground”.
• Every figure in our technical record can be traced back to its source document. For a company heading toward resource definition, that audit trail is not optional it is essential.
• Handwritten field books are still how exploration data starts life. What has changed is how quickly we can turn them into something the whole team can work with.
• AI allows data queries to be performed and reported quickly assisting the onsite staff to focus their attention.

The Use of On-site Drones

• We have the ability collect accurate and up-to-the-minute information on the property and create accurate maps because we can fly the property ourselves and process the imagery in-house.
• Being able to look at Bald Hill from the air whenever we need to gives us a real operational advantage.
• From the drone survey ATMY staff can create detailed maps to aid the exploration efforts, to track roads and accurately plot drill holes and trench locations
• Most exploration still runs on imagery that is years old. Ours is current, it is centimeter-accurate, and it was flown by our own team.

Mr. James Atkinson PGeo, CEO of Antimony Resources commented, “We have continued drilling on the Mine Zone, the focus in-filling 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 is being incorporated into an update Mineral Model which is expected in the early weeks of September. Drill Hole BH-26-06 missed the mineralized zone due to extreme curvature of the drillhole. This condition is rare on the Bald Hill property but does occur in any drilling program. We are very proud of the Software and Data Management Programs developed by our staff. The database for the Bald Hill Project is very comprehensive, and the database contains all aspects of the exploration program being carried out. The data management programs were developed in-house and were designed to be compatible with the drill-hole logging methods being used by our geologists. This meant that there was no learning curve to use the new system which incorporates AI Software. The AI is very useful for myself and the other technical staff because we can quickly receive answers from the database to our questions about the mineralization. This allows us to try new ideas, gather information and evaluate models of mineralization very quickly. For example, I can ask for the average gold assays from our drilling and get the result in hours instead of days or weeks. We can also produce various sections and plans of mineralization very quickly by asking the AI to create them.”

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 25, 2026). 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.

Press Release dated July 27,2026 detailed the geological descriptions of the first 8 drillholes into the Central Zone. The presence of stibnite mineralization (the main host for the antimony mineralization) has been noted in these holes. Assays have not been received for these holes.

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.

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.
