ANTIMONY RESOURCES CORP. (ATMY) (ATMYF) (K8J0) DISCOVERS EXTENSION OF THE MASSIVE ANTIMONY-BEARING STIBNITE MINERALIZATION AT THE MARCUS (WEST) ZONE

Antimony Resources Corp.'s field crews continue to expose massive antimony-bearing stibnite mineralization at the newly discovered Marcus (West) zone on the Bald Hill antimony project in New Brunswick, Canada.

Highlights:

• Trenching 30 metres south of the area of the discovery boulder (see press release dated February 17, 2026) has encountered stibnite in bedrock.
• Geological descriptions of the mineralized zones include samples with massive stibnite mineralization.
• Mineralization resembles the Main zone in stibnite concentration.
• Drilling on the Main zone is continuing, with drilling from both the east and west intersecting antimony-bearing stibnite mineralization in the Main zone.
• Definition drilling totalling 6,500 metres of the 10,000-metre program has been completed to date.
• Future exploration by trenching will be focused on the Central area, where antimony-bearing stibnite has been identified from assays in past exploration, which have not been extensively explored.

As reported in the press release dated Feb. 17, 2026, the Marcus (West) zone was discovered during road building on the west side of the Bald Hill Main zone in January, 2026. The mineralization in this area is new to the project and had never been seen previously to the company's exposure. Antimony Resources has continued its trenching program to determine the extent of the surface exposure of mineralization in this area.

Trenching approximately 30 metres south of the initial discovery boulder (see press release dated Feb. 17, 2026) has exposed additional massive antimony-bearing stibnite mineralization within the bedrock. This mineralization resembles the initial discovery boulders and extends the area of mineralization to the south. The mineralization has now been exposed over a distance of approximately 80 metres. Trenching with washing and sampling is continuing in this area.

Jim Atkinson, PGeo, chief executive officer of Antimony Resources, commented: "The work by our field crews continues to amaze and please us. They have continued to explore through the winter months. Like the proverbial postman -- 'neither rain nor snow nor sleet shall deter them.' They continue to expand the potential of the Bald Hill antimony project through trenching and sampling on the Marcus (West) zone. Their efforts have been very successful. The Marcus (West) zone is shaping up to be a significant addition to the potential of the Bald Hill antimony project. Their next area of focus will be the recently reidentified Central zone to the south of the Main zone, where 2.8 per cent antimony over eight metres was described in past trenching. Drilling in the area will follow the trenching and sampling program. Drilling on the Main zone continues with two drill rigs focused on this area. They have reached a total of approximately 6,500 metres of our proposed 10,000 metres of definition drilling."

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.
• There is potential to expand based on recently discovered targets and additional claims added to the property to the west, south and east.
