Arizona Gold & Silver Inc. (TSX-V: AZS) (OTCQB: AZASF) is pleased to announce a vein intercept of 22.47 metres grading 3.05 grams per tonne gold, including 11.5 gpt gold across 1.59 m and 6.41 gpt gold across 3.69 m from drill hole PC25-154 at the Perry Zone at the Philadelphia Project. The high grades coincide with zones of yellow quartz within an impressive epithermal quartz and bladed calcite-bearing vein system. Results continue to indicate that the mineralization in the system is getting stronger with depth.  Yellow quartz is associated with high gold grades throughout the district.

Perry Vein Core Hole PC25-154

The Perry Vein is a vein located east of and across a drainage from the Rising Fawn zone that has been the focus of drilling previously. The Perry Vein is a distinct mineralized zone within the overall gold-mineral system on the property. It is separated from the Rising Fawn zone by 30-60 metres.

Hole PC25-154 continues our earlier success in PC25-136 in demonstrating that the Perry Vein increases in thickness and grade with depth (new release dated April 7, 2025).  Drill hole PC25-154 was specifically designed to test below drill hole PC25-136 to determine the continuity of mineralization down dip.  Visually our geologist reported more yellow quartz than up dip on that drill section.

Hole PC25-154 assays are as follows:

True widths are approximately 65% of drilling thicknesses.

Vein textures demonstrate classic epithermal features, including colloform and ginguro banding and cockscomb textures. Yellow quartz is abundant, similar to high-grade zones in the nearby Oatman gold mines.  Importantly, this intercept looks to be shallow in the vein system based on the abundance of bladed calcite.

Mr. Greg Hahn, VP Exploration commented, “Drill hole PC25-154 is exciting.  It demonstrates increasing concentrations of gold and favourable vein textures with depth.  Almost the entire width of the vein carries +3 gpt gold.  Yellow quartz is more abundant than what was present in holes up-dip.  In addition, we are now seeing two zones of high grade rather than just one, another indication that the system is getting stronger with depth.  This provides encouragement for core hole PC25-155 currently in progress.  That hole is approaching the projection of the top of the vein 60 metres (200 feet) down-dip from PC25-154.  Currently we are within 15 metres (50 feet) of the top of the target and seeing leakage into the hanging wall volcanics. Leakage is in the form of bladed calcite veins with replacement by yellow quartz.  Normally yellow quartz does not appear so far above the vein.”

Exploration Going Forward

Drilling on the Philadelphia Project continues to test down dip of the Perry Vein mineralized intercepts reported in this release.  Drilling on the adjacent Rising Fawn Zone has been completed for the present until assays on the drilled holes are received from the analytical laboratory. Assays on hole PC25-154 were rushed, which displaced work and progress on the previously submitted holes.

QA/QC Program

All HQ-sized core samples were shipped to the Skyline Labs facility in Tucson, Arizona, where the samples are inventoried, sawed in half, with half of the core sampled and half preserved for future reference, sampled, crushed and pulverized.  All core was sampled in 1-2 metre intervals based upon mineralogy and textures observed by the core logging geologist. Gold is determined by fire assay with an AA finish and silver is determined by ICP-MS methods within a multi-element suite. Over-limits on gold (+5 gpt Au) are determined by fire assay 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’s laboratory facility in Tucson, Arizona, in addition to the independent QA/QC protocols of Skyline Labs.
