Focus of the Drilling will be on Expansion Drilling not Definition Drilling.

Vancouver, May 7, 2026 - Antimony Resources Corp. (CSE: ATMY) (OTCQB: ATMYF) (FSE: K8J0) (the "Company" or "Antimony Resources" or "ATMY") is pleased to announce that it will be commencing the next phase of exploration at the Bald Hill Antimony Project in the second week of May. The program will comprise of expansion drilling at the Main Zone, drilling on the three newly discovered mineralized zones and regional exploration on the expanded property which now comprises 37 square kilometers.

Highlights

Corporate update

• Recent Definition Drilling Program has completed over 13,000 meters of drilling in 43 drill holes.
• A total of 77 drill holes totaling over 25,000 meters have been completed by ATMY since the beginning of the program in April 2025.
• Focus has been on expansion of the Main Zone at Bald Hill with extensions of mineralization to the north and south.
• New exploration will be focused on resource expansion.
• Trenching has been completed on Marcus Zone, BH Central Zone and BH South Zone which has exposed additional antimony-bearing stibnite mineralization in these three areas
• Drilling has been planned for all three areas.
• Return of chemical analyses for soil samples has identified three areas of anomalous antimony in the soil on the recently acquired Second Run claims approximately 3 km south of Bald Hill.
• One soil anomaly is not fully defined, and further sampling is planned in this area.
• Over 1500 samples of drill core have been forwarded to the assay laboratory for analysis during the recent program. ATMY expects to begin receiving results in May.

Expanded Field Program for Q2 and Q3 2026

The next exploration program at the Bald Hill Antimony Project will commence in May and will have two objectives - to advance the project and to further de-risk the project.

1. Advance the Project

The program will focus on expansion of the mineralized zones:

• Completion of a 13,000-meter drill program at Bald Hill Main Zone to expand mineralization at depth and along strike.
• Completion of 6,000 meters of preliminary exploration drilling at the three newly defined zones in the Main Zone Area - Marcus, BH Central and BH South.
• Planned target areas are in close proximity to the west, and south of the known deposit and are readily accessible and are shown on Figure 1.
• Prospecting, mapping, trenching and sampling at the newly defined soil anomalies on the Second Run claims - SR1. SR2 and SR3.
• Expanded soil coverage at SR1 and additional soil sampling over the remaining property.
• Complete additional exploration to discover and determine potential across the entire 37 square kilometer property.
• Conduct a property-wide soil survey with the collection of over 1500 samples.

2. De-Risking the Project

The factors in this case include:

• Evaluate the size and continuity of the antimony mineralization using 3-D modeling and computer-based data analysis.
• Complete detailed metallurgical studies on the antimony mineralization.
• Completion of Environmental baseline and technical studies to support permitting, in collaboration with First Nations communities, local stakeholders and the New Brunswick Government.
• Technical Gap Analysis by SRK to assist in the Roadmap to Permitting and determine factors that may affect viability of the project.
• Evaluation of several potential project plans and configurations for a possible mine and infrastructure layout.
• Complete Permit application for Bald Hill Antimony Project by Q4 2026/Q1 2027.
• Contract with metal marketing companies to assess the possibility of developing an off-take agreement for any product resulting from mining at Bald Hill.

Mr. James Atkinson, P.Geo. CEO of Antimony resources commented "We are very excited to get back to work on the Bald Hill Project. We took a break in the drilling to allow for assays to be returned from the lab and to allow for maintenance on the drills which have been going strong since returning after Christmas Break. They have produced over 13,000 meters of core, drilling basically non-stop since the program started in February.

The soil sampling completed so far has been very effective in revealing areas of anomalous antimony on the Second Run claim south of the Main Zone and we are anxious to complete sampling over the entire 3700 hectare property."

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 Antimony Project is the highest-grade antimony deposit in North America with mineable widths indicated by drilling.
• Drilling has outlined an antimony deposit, the Main Zone, over a strike length of 600 meters 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.
