Arizona Gold & Silver Inc. (TSX-V: AZS) (OTCQB: AZASF) is pleased to announce it has received assays from the latest core hole, PC25-157.  In this drill hole the mineralized structure is wider due to the presence of gold in additional host rocks. Drilling is continuing with PC25-158 in progress.

Highlights of Core Hole PC25-157

• Hole located 50 metres north of high-grade intercept in PC25-156 (reported Sept. 17, 2025).
• 6.28m at 7.02gpt from 278.18m downhole
• 1.52m at 13.8 gpt from 284.54m downhole
• 3.35m at 8.32 gpt from 335.98m downhole
• All within 76.5m at 2.36 gpt from 265.85m downhole
• Multiple rock types now mineralized 

Greg Hahn V.P. Exploration comments: ”The Perry vein was again intersected as we predicted.  Significantly, stockwork quartz-calcite veining in the hanging wall of the vein (primarily in andesite), carries appreciable amounts of gold and silver not encountered in previous holes. The thick interval of veining continues in hole PC25-158, recently completed. This developing stockwork zone is changing our interpretation of the nature of mineralization along the mineralized corridor. It definitely adds a potentially bulk-mineable component to the deposit as it swells in thickness. I look forward to the results for PC25-158.”

Core Hole PC25-157

Core hole PC25-157 was collared at a 24-degree azimuth and -80 degree inclination and intersected stockwork quartz+calcite mineralization in andesite, rhyolite, and conglomerate immediately above the Perry vein.  Mineralization starts at 265.85m in andesite and continues into rhyolite at 284.54m and conglomerate at 299.76m before encountering the Perry Vein itself at 313.69m. High grade intervals are associated with higher densities of quartz+calcite veins.  The calcite demonstrates abundant bladed textures commonly replaced by predominantly green and yellow quartz. The nearest previous drill holes to this section of holes intersected the mineralized zone roughly 200m to the west.  Mineralization in those drill holes is in granite instead of andesite. See the accompanying 24 degree azimuth section that includes holes PC25-156, PC25-157, and PC25-158. The entire interval from 265.85m to 342.38m is summarized in the table below.

Summary Assay Results for Core Hole PC25-157

True thickness of the above intercepts is estimated at 63% of drilled thickness.

Core Hole PC25-158

Core hole PC25-158 is targeted to intersect the Perry Vein 60m north of the intercept in PC25-157 and 110m north of the high-grade intercept in PC25-156.  PC25-158 encountered abundant stockwork quartz+calcite veining in andesite. Visually the zones containing quartz+calcite veins are thicker than the higher grade intervals in hole PC25-157. Conglomerate is also visually mineralized before encountering the Perry Vein. The hole penetrated the Perry Vein 335.5m-339.9m and entered a barren andesite dike. PC25-158 was terminated in barren andesite at 374.08 metres. The next hole (PC25-159) will test the target another 60m north along strike of hole PC25-158.

QA/QC Protocols

The HQ core is delivered in its entirety to Skyline Labs in Tucson, Arizona where it is sawed in half based upon sample intervals designated by the project geologist. Half of the core is crushed, pulverized and analyzed by fire assay with an A.A. finish for gold.  A four-acid digestion and ICP analysis is used for silver and trace metal determinations. Any values greater than 5 gpt gold are re-run by fire assay with a gravimetric finish.  The remaining core half is preserved for further studies.  Coarse rejects from crushing will be saved for metallic screen analyses, if warranted, and future metallurgical testing.
