Antimony Resources Corp. (CSE: ATMY) (OTCQB: ATMYF) (FSE: K8J0)

Announces Assay Results up to 44.2% Antimony from Trenching of the South

Zone at Bald Hill.

Vancouver, Canada – June 8, 2026, - Antimony Resources Corp. (CSE: ATMY) (OTCQB: ATMYF)

(FSE: K8J0) (the “Company” or “Antimony Resources” or “ATMY”) is pleased to announce that it

has received assay results from rock samples collected during the trenching program at the

South Zone at Bald Hill. These samples originate from trenches excavated along a distance of

over 200 meters along the zone during the winter.

Highlights

• Assays for rock samples have been received from the South Zone at Bald Hill.

• Values from 38 samples collected over a distance of 200 meters during the

trenching program average 19.5% antimony (Sb) with values up to 44.2% Sb.

• The South Zone is located approximately 900 meters south of the Main Zone.

• The zone trends in a Northwest-Southeast direction similar to the Main Zone.

• The South Zone trend appears to be parallel but off set from the Main Zone.

• Drilling will be conducted in this area as part of the ongoing “Regional Exploration

Program” being carried out this spring.

• These results outline a new area of potential for antimony mineralization separate

from the Main Zone.

• The South Zone is one of the “New Zones” defined by recent investigations on the

property.

Note that these are “grab samples” from the exposed veins in the trenches and may not be

representative of the final grade of mineralization. in the South Zone.

The South Zone is one of the “New Zones” of stibnite-bearing antimony mineralization recently

identified by ATMY (see Press Release Dated March 26 2026). The samples reported in this

release were collected from a series of trenches completed last winter across the South Zone

over a distance of approximately 200 meters. The mineralization uncovered is described as

consisting of stibnite occurring associated with brecciated sediments.

Mr. James Atkinson PGeo, CEO of Antimony Resources commented “the assays from the

2026 winter trench program at the South Zone have returned very high-grade results. These

samples indicate the expanded potential offered by the New Zones on mineralization

identified by field staff at Bald Hill. The field staff should be commended for obtaining

these results during the winter.

We note that these assay values for antimony are similar to previously released results

obtained in this area in 2024 (9.2% Sb over 2.6 meters) but show that the mineralized zone

is much larger than previously thought.

Our next drilling program has already begun and will test the extent of mineralization in this

and the other recently defined New Zones.”

Mr. Atkinson continues: “The recent visit by staff of the New Brunswick Minister of Natural

Resources detailed in our recent Press Release (May 1, 2026) allowed us to showcase our

Project. We thank the NB Natural Resources staff for taking time from their busy schedules

to visit our site. Their follow-up comments highlight the support of the New Brunswick

government for mining and the importance of the Bald Hill Antimony deposit in the

province”

The figure below shows the relative location of the explored areas on the Bald Hill Project.

On it we can see the location of the Main Zone and the “New Zones” in the northern part of

the original claim (4633). Other claims which comprise the property are also identified. A

significant amount of the large property (over 3700 Hectares) is still to be investigated.

The next phase of exploration will include an airborne magnetic and electromagnetic

survey, soil sampling, geological mapping and sampling. Further trenching will be

completed in areas of interest.

SR1 and SR2 Soil Anomalies are currently being explored while trenching has been

completed on the Marcus, Central and South Zones.

QA/QC

Samples The bags are sealed and placed in larger canvas bags for shipment to the Activation

Labs Processing facility in Fredericton where they are crushed and prepared for shipment to the

assay lab in Ancaster Ontario. The samples are analyzed using Actlabs Method Code 1E3 Aqua

Regia ICPOES for the multi element and Code 1A2 Fire Assay AA for gold.

Quality Assurance and Quality Control (QA/QC) samples are inserted in the sample runs which

include a known standard for antimony and gold, a core duplicate, a blank, and a pulp duplicate.

Activation Labs also has standard QA/QC protocols which are reported with each assay batch.

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 is the highest-grade antimony deposit in North America

with mineable widths indicated by drilling.

• Drilling has outlined an antimony deposit in the Main Zone over 600 meters long 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.
