Arizona Gold & Silver Inc. (TSX-V: AZS) (OTCQB:AZASF) announces further positive results from the on-going core drilling program at the Philadelphia Project in Arizona. Core hole PC25-156 has intersected approximately 10 metres of unbrecciated banded and massive vein quartz within a 35.7m intercept of quartz vein and quartz vein breccia. This is the first time a drill hole has been deep enough to intersect intact vein with the classic epithermal vein textures typical of the high grade deposits known in the nearby Oatman mining camp, 10 kms south of the property. Furthermore the new drill intercept represents a 59% increase in true thickness over drill hole PC25-155 that cut the zone 60m up dip (see News Release dated August 6, 2025).

Crenulation banding in yellow and brown quartz

Greg Hahn, VP Exploration reports: “This drill hole confirms our geological modelling. My understanding of this low sulphidation epithermal system predicted that with depth the system would be wider and potentially much higher grade as we penetrate the “boiling zone” of the system. We continue to see a decrease in bladed calcite and an increase in quartz replacement of bladed calcite.

“In addition, the interior of the unbrecciated vein displays classic epithermal textures including finely layered banding of colloform layering and thin alternating compositional banding. Yellow quartz dominates the upper part of the intercept and green, gray, and brown quartz dominate the lower portion of the vein intercept. This is also a feature we have never witnessed in drill core before. In short we believe the vein system has the potential to rapidly open up into high-grade zones capable of delivering substantially increased grades.

Greg Hahn continues “The intercept reported here is at +300m depth in the vein system and remains open down-dip. Assuming symmetry across the dip extent drilled our modeling predicts this vein will continue down dip for another +/- 300m at least. Demonstrating the continuity of this vein along a strike length of 1 kilometre would establish a very significant discovery.“

True thickness of intercepts in PC25-156 are approximately 64% of drill thickness. Core from drill hole PC25-156 has been delivered to Skyline Labs in Tucson for sawing, sampling, sample preparation and assaying.”

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, sample preparation and assaying are 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.
