Mr. Jim Atkinson reports

ANTIMONY RESOURCES CORP. (ATMY) (ATMYF) (K8J0) IS PLEASED TO ANNOUNCE THE NEXT PHASE OF EXPLORATION AT THE BALD HILL ANTIMONY DEPOSIT IN NEW BRUNSWICK, CANADA

Antimony Resources Corp. will be commencing the next phase of exploration at the Bald Hill antimony project in the second week of May. The program will comprise 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 kilometres.

Highlights

Corporate update:

• Recent definition drilling program has completed over 13,000 metres of drilling in 43 drill holes.
• A total of 77 drill holes totalling over 25,000 metres have been completed by Antimony Resources 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 three kilometres south of Bald Hill.
• One soil anomaly is not fully defined, and further sampling is planned in this area.
• Over 1,500 samples of drill core have been forwarded to the assay laboratory for analysis during the recent program. Antimony Resources 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 derisk the project.

1. Advance the project

The program will focus on expansion of the mineralized zones:

• Completion of a 13,000-metre drill program at Bald Hill Main zone to expand mineralization at depth and along strike;
• Completion of 6,000 metres 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.
• 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-kilometre property;
• Conduct a property-wide soil survey with the collection of over 1,500 samples.

2. Derisking the project

The factors in this case include:

• Evaluate the size and continuity of the antimony mineralization using 3-D modelling 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 road map 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 the Bald Hill antimony project by Q4 2026/Q1 2027;
• Contract with metal marketing companies to assess the possibility of developing an offtake agreement for any product resulting from mining at Bald Hill.

James Atkinson, PGeo, chief executive officer 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 metres 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 3,700-hectare property."

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

Highlights:

• Bald Hill is a well-known, high-grade antimony deposit in southern New Brunswick, Canada;
• Drilling has outlined an antimony deposit in the Main zone over 700 metres long and to a depth of at least 350 metres and open in all directions;
• Widths of mineralization average three to four metres 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 at approximately 2.7 million tonnes with a grade between 3 per cent and 4 per cent antimony; 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.
