Arizona Gold & Silver Intersects 14.5 Grams Per Tonne Gold Within 22.26 Metres (73 Feet) Of 4.24 gpt Gold at Philadelphia Project, Arizona

Aug 6, 2025

Vancouver, British Columbia, August 6, 2025 – Arizona Gold & Silver Inc. (TSXV: AZS) (OTCQB: AZASF) is very pleased to announce further positive results from the on-going core drilling program at the Philadelphia Project. Highlights include 14.5 g/t over 1.52 meters within 4.24 g/t over 22.26 meters. Results from core hole PC25-155 demonstrate continuity of impressive vein thickness and an increase in grade as drilling progresses down dip on the vein.

This intercept is within a single massive composite and brecciated quartz vein and represents a 40% increase in grade over the intercepts in hole PC25-154, which is located about 60 meters up dip from PC25-155, and has approximately the same drill thickness. True thickness of intercepts in PC25-155 is approximately 57% of drill thickness. The results are shown on the accompanying section.

Greg Hahn reports: “Core hole PC25-155 has delivered an exceptional intercept, showcasing strong continuity of impressive vein thickness with a notable increase in gold grade with depth to date. The evolving vein textures—particularly the increasing replacement of bladed calcite by yellow quartz—are classic markers of a high-grade epithermal system and signal that we are approaching the heart of the boiling zone, where gold grades typically spike significantly.”

“These textures are similar to those seen in the historic Oatman Gold Mining District, just 10 miles south, which produced over 2 million ounces of gold from similar high-grade veins. Like Oatman, we believe the Philadelphia vein system has the potential to rapidly open up into high-grade zones capable of delivering substantially increased grades.”

“Hole PC25-156, currently advancing toward the target zone below hole 155, is poised to test this exciting interpretation. If the system continues to behave as expected, we could be on the cusp of unlocking a major high-grade gold discovery.”

Hole 156 in progress

Core hole PC25-156 is in progress and at 872 feet (265.85 meters) currently, within approximately 200 feet (60.98 meters) of the top of the targeted vein (see accompanying section).

Mike Stark reports: “I’m very pleased to share our latest results with our shareholders. We continue to report high-grade gold intercepts with very impressive thicknesses. Hole -155 has significantly increased our confidence in the potential of this zone.

The results from Hole -156 will be instrumental in guiding our next phase of drilling. It will likely focus on strike in both directions which will expand the current mineralized footprint. Encouragingly, our geological model is showing strong validation. We have shallow intercepts on this vein system over a strike length of one kilometer, and by continuing to drill at depth along strike (north and south), we can begin to more accurately assess the size potential of this zone.”

QA/QC

All core holes are HQ sized. All core samples are sawed in half as stipulated by the project geologist, with one half sampled at designated intervals for assaying and the other half preserved for further studies. Once sampled, the individual samples go through crushing, splitting, pulverizing, and further splitting before a sample split is delivered for assaying. All core sawing and sample preparation and assaying was conducted by Skyline Laboratories, an ISO 9001 certified independent lab. Core was trucked to Skyline Labs in Tucson, Arizona. All material handling is done under a strict chain of custody protocol. Gold is determined by fire assay with an AA finish and silver is determined by four-acid digestion and ICP-MS methods within a 31-element suite. Samples returning greater than 5ppm gold are re-assayed with a gravimetric finish.

The Company maintains its own program of inserting Standard Reference material in the form of standards and blanks to the sampling stream, prior to being shipped to Skyline Labs in Tucson, Arizona, in addition to the independent QA/QC protocols of Skyline Labs.
