ANTIMONY RESOURCES CORP. (ATMY) (ATMYF) (K8J0) INTERSECTS HIGH-GRADE ANTIMONY-BEARING STIBNITE MINERALIZATION OF 4.38% ANTIMONY (SB) OVER 7.05 METERS (M) INCLUDING 9.76% SB OVER 3.15 METERS

Antimony Resources Corp. has received assay results for the final drill hole in the 2025 program -- drill hole BH-25-34. The drill hole intersected high-grade antimony-bearing stibnite mineralization.

The 3-D mineralization model for the Bald Hill main zone has been updated with the drilling completed in 2025.

Highlights:

• Drill hole BH-25-34 returned antimony assays of 4.38 per cent antimony (Sb) over 7.05 metres (m), including 9.76 per cent Sb over 3.15 metres.
• Drill hole BH-25-34 has extended the antimony-bearing stibnite mineralization of the main zone to the north and to depth.
• An updated 3-D model generated longitudinal section showing trends of higher-grade antimony assays.
• The 2025 drilling program totalled over 8,000 m and identified significant expansion of the potential of the main zone to the north and at depth.

Results

Drill hole BH-25-34 intersected 4.38 per cent Sb over 7.05 m from 276.6 to 283.65 m depth, including 9.76 per cent Sb over 3.15 m from 280.5 to 283.65 m. This drill hole was testing the northern extension of the main zone.

The 2025 program, which totalled over 8,000 m, was focused on expanding the size of the Bald Hill main zone. The drill hole locations were focused on defining the zone along strike and to depth. In total, 34 drill holes were completed in the program, and the mineralization was traced for a distance of over 600 m in a north-northwest-south-southeast direction and was intersected to a depth of 400 m.

Drill hole BH-25-34 reported in this news release was one of the farthest north and deepest holes completed. The results of the drilling completed in 2025 was incorporated into a 3-D model. The model is being utilized in the follow-up definition drilling program, which began in February, 2026. The program will be terminated on April 28. Assays from these drill holes are being processed at Activation Laboratories in Stoney Creek, Ont.

The current definition drill program will be terminated at the end of April, with over 12,500 m completed. Assays for these holes are being processed.

Drilling to date on the Bald Hill main zone totals over 25,000 m.

A 11,000 fully financed drill program is planned to commence in mid-May, which will focus on the newly discovered mineralized zones outside of the main zone. These are the Marcus zone and two areas identified by a previous operator but not explored in detail -- the central zone and the south zone.

New zones of antimony-bearing stibnite identified in 2025

Marcus West zone

Trenching has exposed the zone of mineralization for approximately 100 m in a north-south direction. Antimony-bearing stibnite in outcrop on surface can be seen over a thickness of at least m and can be up to 11 m wide.

BH Central

Trenching in 2014 by the previous explorer discovered a new area of antimony mineralization approximately 150 m south of the main zone. It appears to be an extension of the main zone. The trenching recovered 2.8 per cent Sb over 8.1 m from channel sampling, trenching is currently being undertaken by the company on the stibnite-bearing zone.

BH South

Trenching in 2014 on the south end of an antimony soil anomaly discovered a new area of antimony mineralization, which gave 9.04 per cent Sb over 2.6 m, including 12.32 per cent over 1.7 m, from channel sampling. It is located approximately 1.0 kilometres (km) along trend to the southeast of the Bald Hill deposit. Recent trenching by the company has exposed the stibnite-bearing zone for over 150 m.

Regional exploration

This summer, further exploration will be completed on the newly acquired claims to the west, east and south extensions of the property. This is budgeted to include large soil sampling programs, prospecting and follow-up trenching, and potentially drilling. A detailed airborne survey with magnetic and electromagnetic detectors is being planned.

Jim Atkinson, PGeo, chief executive officer of Antimony Resources, commented: "We believe that the recent drilling and the discovery of new mineralized zones has increased the mineral potential of the Bald Hill antimony property. The results from drill hole BH-25-34 gave high-grade antimony results and expanded the footprint of the mineralization. The 3-D modelling completed by Motherlode Consulting has shown the location of zones of high-grade antimony mineralization, which can be explored further. This model is being updated as assay results are obtained for the latest drilling."

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

Highlights:

• Bald Hill is a high-grade antimony deposit in southern New Brunswick, Canada.
• Drilling has outlined an antimony deposit in the main zone over 700 m long and to a depth of at least 400 m and open in all directions.
• Widths of mineralization average three to four 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, is 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, 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.
• There is potential to expand, based on recently discovered targets and additional claims added to the property to the west, south and east.
