ARIZONA GOLD & SILVER DRILLS MULTIPLE HIGHER GRADE GOLD INTERVALS WITHIN SIGNIFICANTLY WIDER MINERALIZED STRUCTURE - 76.5 METRES AT 2.36 GPT GOLD AND 16.24 GPT SILVER BEGINNING AT 265.8 METRES ON THE PHILADELPHIA PROJECT, ARIZONA

Arizona Gold & Silver Inc. 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);
• 6.28 metres at 7.02 grams per tonne from 278.18 m downhole;
• 1.52 m at 13.8 g/t from 284.54 m downhole;
• 3.35 m at 8.32 g/t from 335.98 m downhole;
• All within 76.5 m at 2.36 g/t from 265.85 m downhole;
• Multiple rock types mineralized.

Greg Hahn, vice-president, exploration, commented: "The Perry vein was again intersected as we predicted. Significantly, stockwork quartz-calcite veining in the hangingwall 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-minable 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 minus-80-degree inclination, and intersected stockwork quartz plus calcite mineralization in andesite, rhyolite and conglomerate immediately above the Perry vein. Mineralization starts at 265.85 m in andesite, and continues into rhyolite at 284.54 m and conglomerate at 299.76 m before encountering the Perry vein itself at 313.69 m. High-grade intervals are associated with higher densities of quartz plus 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 200 m to the west. Mineralization in those drill holes is in granite instead of andesite. The entire interval from 265.85 m to 342.38 m is summarized in the table below.

Core hole PC25-158

Core hole PC25-158 is targeted to intersect the Perry vein 60 m north of the intercept in PC25-157 and 110 m north of the high-grade intercept in PC25-156. PC25-158 encountered abundant stockwork quartz plus calcite veining in andesite. Visually, the zones containing quartz plus 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 335.5 m to 339.9 m, 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 60 m north along strike of hole PC25-158.

Quality assurance/quality control protocols

The HQ core is delivered in its entirety to Skyline Labs in Tucson, Ariz., 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 AA finish for gold. A four-acid digestion and ICP analysis is used for silver and trace metal determinations. Any values greater than five g/t gold are rerun 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.
