Antimony Resources Corp. (ATMY) (ATMYF) (K8J0) Discovers New Massive Stibnite Mineralization at the Marcus (West) Zone and Have Exposed the Mineralization in Bedrock over a Distance of 25 Meters

Rhea-AI Summary

Antimony Resources (OTCQB: ATMYF) discovered expanded massive stibnite mineralization at the Marcus (West) Zone, with bedrock exposure over a 25-meter distance and trenching showing South Zone mineralization over 150 meters.

A 2026 definition drill program (currently two rigs, third added early February) targets the Bald Hill Main Zone along 600 meters to depths of at least 300 meters, aiming to support a Maiden Resource. A 2025 NI 43-101 technical report cites an approximate target of 2.7 million tonnes at 3–4% Sb, but the company notes this is conceptual and unconfirmed.

Positive

• Marcus (West) discovery: stibnite exposed in bedrock over 25 meters
• Trenching identified stibnite across 150 meters on South Zone
• Drill program targeting 600 m strike to 300 m depth with 3 rigs
• NI 43-101 target approx. 2.7M tonnes at 3–4% antimony (conceptual)

Negative

• Estimated quantity and grade are conceptual and unconfirmed
• Insufficient exploration to define a mineral resource; further work uncertain

Vancouver, British Columbia--(Newsfile Corp. - February 3, 2026) - Antimony Resources Corp. (CSE: ATMY) (OTCQB: ATMYF) (FSE: K8J0) (the "Company" or "Antimony Resources" or "ATMY") is pleased to announce that it has expanded and outlined further massive stibnite mineralization at the Marcus (West) Zone and have exposed the mineralization in bedrock over a distance of 25 meters. It is thought that this is a separate zone from mineralization at the Main Zone. Additional trenching and sampling on the newly discovered Marcus (West) Zone and the Bald Hill South mineralization is planned for the 2026 exploration season.

It can be seen from Figure 1 that the newly discovered mineralization can easily be tested by shallow drilling from locations such as BHW26-01 to 04 simply by turning the drill 180 degrees.

The 2026 Definition Drilling Program has commenced to delineate the mineralization of the Main Zone at Bald Hill with 2 drill rigs. A third drill rig will be added in early February. This drilling is focused on detailed sampling of the Bald Hill Main Zone over a distance of 600 meters to a depth of at least 300 meters. It is thought that the proposed drill density will be sufficient for our consultants to calculate a Maiden Resource for the Bald Hill Project.

The new discoveries made by our Field Crew on the property will be part of our ongoing exploration program. Trenching on the South Zone has identified stibnite bearing boulders and stibnite in outcrop in this area over a distance of 150 meters.

Bald Hill Antimony Project

Highlights

• Bald Hill is a well-known, high-grade antimony deposit in southern New Brunswick, Canada.
• Drilling has outlined an antimony deposit over 700 m. long
• Widths of mineralization average 3 to 4 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 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 additional known targets and additional claims added to the property

FAQ

What did Antimony Resources (ATMYF) find at the Marcus (West) Zone on February 3, 2026?

The company discovered expanded massive stibnite mineralization with bedrock exposed over 25 meters. According to the company, field crews found the zone parallel to the Main Zone and plan additional trenching and sampling in 2026.

How extensive is the 2026 drilling program for Antimony Resources (ATMYF) at Bald Hill?

The 2026 definition drill program uses two rigs with a third added in early February to test 600 meters of strike to at least 300 meters depth. According to the company, density aims to support a Maiden Resource calculation.

Does the NI 43-101 report confirm a resource for ATMYF's Bald Hill project?

No—the NI 43-101 report cites a potential target of ~2.7 million tonnes at 3–4% Sb, but this is conceptual. According to the company, there has been insufficient work to confirm a mineral resource and results remain unconfirmed.

What follow-up exploration will Antimony Resources (ATMYF) conduct after the Marcus (West) discovery?

The company plans additional trenching and sampling on Marcus (West) and Bald Hill South during the 2026 season. According to the company, these activities will integrate new discoveries into the ongoing exploration program and drilling plans.

How might the Marcus (West) discovery affect ATMYF's Maiden Resource timeline?

The discovery provides shallow targets easily tested by nearby drill locations, potentially accelerating definition drilling. According to the company, proposed drill density over 600 m and 300 m depth is intended to enable consultants to calculate a Maiden Resource.
