Arizona Gold & Silver Commences 27-Hole Drill Program at Silverton Gold-Antimony Project

Vancouver, British Columbia — June 9, 2026 — Leads & Copy — Arizona Gold & Silver Inc. announced today the commencement of a 27-hole reverse circulation (RC) drill program at its Silverton gold-antimony project in Nye County, Nevada. The project is situated along U.S. Highway 6, between Tonopah and Ely.

The program aims to test high-grade antimony-bearing quartz-stibnite veins, identified through historic and recent surface sampling. The Company's interpretation suggests that the antimony mineralization could be indicative of a deeper, concealed carbonate-hosted gold system.

The 27 RC holes will be drilled from 17 locations, with most holes designed to penetrate 30 to 45 metres to evaluate near-surface antimony mineralization potentially suitable for open-pit mining. Additionally, three holes are planned for depths of approximately 150 metres, with casing for potential future diamond drill extensions targeting deeper geophysical and geochemical features interpreted as prospective for Carlin-type gold mineralization.

GroundTruth Drilling Canada/Nevada has been awarded the contract for the RC drilling.

“Drilling at Silverton marks an important step in advancing a project that combines significant near surface antimony potential with a deeper gold target in one of Nevada’s premier mineral belts,” said Mike Stark, President & CEO. “Success at Silverton has the potential to take AZS to another level for investors. The project is fully funded.”

Dr. Lex Lambeck, VP Exploration, stated, “Silverton exhibits many of the geological characteristics associated with both a significant antimony system and a deeper Carlin-type gold target. The current drill program is designed to evaluate the continuity and orientation of the antimony-bearing structures while advancing our understanding of the broader hydrothermal system and refining targets for future deeper drilling.”

The Silverton project is located in central Nevada, an area influenced by Oligocene magmatism and subsequent Basin and Range extension, which reactivated pre-existing structures and focused hydrothermal fluid flow. Oligocene volcanic rocks overlie Upper Devonian carbonate units, including slope breccias rich in organic material, creating a favorable volcanic-over-carbonate geological setting.

Antimony mineralization is present as quartz-stibnite veins and stockworks within silicified and argillized ash-flow tuffs, hosted in a structurally controlled corridor approximately 900 by 400 metres. The Company believes this antimony-rich system may represent an upper-level expression of deeper carbonate-hosted mineralization, supported by silicification, decalcification, jasperoid development, elevated As-Sb-Hg pathfinder geochemistry, anomalous gold values, and a conductive MT anomaly approximately one kilometre below the surface.

As previously reported on October 8th, 2025, surface sampling at Silverton yielded assays up to 7.95% Sb from quartz-stibnite veins. Historical work also identified widespread anomalous antimony values associated with gold-bearing hydrothermal alteration. Historic drilling by Newcrest Resources Inc. intersected anomalous antimony mineralization in 15 RC holes on the property, including an interval reported as 6 metres grading greater than 1% Sb in hole S-18. Historic over-limit assays were not completed.

The United States Geological Survey (USGS) classifies antimony as a critical mineral due to its importance for national security and industrial supply chains.

The current drill program objectives include testing the continuity and orientation of quartz-stibnite veins, evaluating the broader altered structural corridor, assessing associated gold mineralization, and advancing targeting for the deeper MT anomaly and interpreted carbonate-hosted gold system. Assay results will be released as they become available.
