Arizona Gold & Silver Hits High-Grade Gold-Silver Intercept at Philadelphia Project

Vancouver, British Columbia — September 17, 2025 — Leads & Copy — Arizona Gold & Silver Inc. (TSXV: AZS) (OTCQB: AZASF) announced positive assay results from its core drilling program at the Philadelphia Project in Arizona. Hole PC25-156 returned 9.04 grams per tonne (gpt) gold and 34 gpt silver over 20.43 metres.

Highlights include the confirmation that the Perry Vein system increases in thickness and grade with depth, with PC25-156 yielding 9.04 gpt Au and 34.0 gpt Ag over 20.43 m from 320.73 m depth, hosted within 5.61 gpt Au and 29.2 gpt Ag over 38.72 m from 312.50 m depth, including 45.60 gpt Au and 54.9 gpt Ag over 1.19 m from 325.64 m depth. Metallic screen analyses are underway for PC25-154, -155, and -156 to evaluate the potential impact of particle gold, and continued exploration drilling is planned with three additional holes to test further vein expansion. The deposit is open in all directions, and an expanded exploration program is planned for 2026, with an amendment submitted to the U.S. Bureau of Land Management to expand the exploration area by 200 acres and prepare 16 new drill pads.

President and CEO Mike Stark said the results validate the untapped potential at depth within the Perry Vein system and that the company is seeing increasing scale and grade as they drill deeper. VP Exploration Greg Hahn added that the drill hole confirms the company is drilling a large and thick vein deposit of gold and silver that continues to increase in grade with depth.

The company has arranged for a core rig to arrive on the property in October to drill the three holes and has submitted an amendment to its Plan of Operations with the US Bureau of Land Management to expand the exploration drilling area by 200 acres.
