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

Executive Summary

• Arizona Gold & Silver Inc. announced the start of a 27-hole reverse circulation (RC) drill program at its Silverton gold-antimony project in Nye County, Nevada.
• The program is designed to test high-grade antimony-bearing quartz-stibnite veins for near-surface open-pit potential, while three deeper holes will target a concealed Carlin-type gold system.
• The exploration program is fully funded, with assay results to be released as they become available.

Key Details

• Drill Program Scope: 27 RC holes from 17 drill pads; most holes 30–45m deep; 3 holes planned to ~150m+ and cased for future diamond drill extensions.
• Contractor: GroundTruth Drilling Canada/Nevada.
• Primary Targets: High-grade antimony mineralization amenable to open-pit mining; deeper carbonate-hosted Carlin-type gold system.
• Geological Setting: Central Nevada within a region of Oligocene magmatism and Basin and Range extension; antimony occurs in quartz-stibnite veins/stockworks within a 900 x 400m structurally controlled corridor.
• Prior Assay Data: Surface sampling returned up to 7.95% Sb; historic drilling by Newcrest Resources intersected 6m grading >1% Sb in hole S-18.
• Project Objectives: Test continuity/orientation of quartz-stibnite veins, evaluate the broader altered structural corridor, assess associated gold mineralization, and advance targeting of a conductive MT anomaly ~1km below surface.
• Funding Status: Fully funded.
• Qualified Person: Dr. Lex Lambeck, SVP Exploration (Certified Professional Geologist).

Notable Quotes

• Mike Stark, President & CEO: “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. Success at Silverton has the potential to take AZS to another level for investors. The project is fully funded.”
• Dr. Lex Lambeck, VP Exploration: “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.”
