Antimony Resources drills 36.0% Sb and 27.0% Sb at Bald Hill Main Zone

Vancouver, British Columbia--(Newsfile Corp. - June 16, 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 additional drilling in the Main Zone at the Bald Hill Antimony project. The results are from drilling which is part of the more than 18,000 meters of drilling planned for Q2/Q3 2026. A portion of drilling in the expanded drill program is intended to expand the mineralization at the Main Zone to the North and South and to depth.

The remainder of the drill targets will be focused on the New Zones recently identified on the Bald Hill Antimony project. Highlights All holes intersected antimony-bearing stibnite in the Main Zone Values up to 36.0% Antimony (Sb), 27.0% Sb and 19.8% Sb Thickness up to 13.2 meters The intersections are at depths up to 240 meters The drill hole intersections include multiple zones of mineralization – Hole BHW-26-04 intersected three zones over a drill hole length of 20 meters and BH-26-15 intersected three zones over a drill hole length of 40 meters The holes show greater width with drill hole BH-26-15 returning 2.85% Sb over 13.2 meters Table 1: Summary of Assay Results for Samples of Drill Core From the Main Zone at Bald Hill Antimony Project   Figure 1: Locations of Drill holes BHW 26-03, BHW-26-04 and BH-26-15 at The Main Zone Bald HIll. Note drilling both from the West and East sides intersect the Main Zone and Create "Scissor" Intersections.

Only Reported Holes are labeled. Drill Holes BHW-26-03 and BHW-26-04 were targeted to extend mineralization to the south.

Drill holes BHW-26- 03 and BHW-26-04 were intended to be "scissor holes" cutting the Main Zone from the west side. These holes are also in the southern extent of the Main Zone and were aimed to test the continuity of mineralization in the southern direction. They successfully intersected antimony mineralization and effectively extended the Main Zone in a southerly direction.

"As we have been describing, the current drill program in the Main Zone will be focused on expanding the known mineralization to the south and north and at depth. Exploration in the New Zones is continuing with drilling on the Central Zone with over 1500 meters completed to intersect below the mineralization exposed in surface trenching." Table 2: Mineralized Intersections. The extent of the mineralized zones in BHW-26-03 and BHW-26-04 on the west Side and BH-26-15 from the east Side are reported.    The next phase of exploration at Bald Hill will also include an airborne magnetic and electromagnetic survey, soil sampling and geological mapping.

Further trenching will be completed in areas of interest especially in the New Zones and in any areas where soil sampling indicates anomalous antimony or other metals. Note SR1 and SR2 in figure 3 show areas which returned anomalous antimony results in soil sampling. Figure 2: Areas of known Antimony Mineralization on the Bald Hill Property.

Note: SR1 and SR2 Soil Anomalies are currently being explored while trenching has been completed on the Marcus, Central and South Zones.

Once the information on core conditions including RQD, lost core etc are recorded and the core is confirmed to be intact and orderly it is logged and marked for sampling by our professional geological staff.

The marked core for sampling is cut by diamond say one half is returned to the box for safekeeping and one half is placed in plastic bags. 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. Activation Laboratories in an internationally accredited assay Laboratory.

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% antimony 1 .

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.
