ARIZONA GOLD & SILVER CORE HOLE PC25-158 INTERSECTS 60.37 METRES AT 4.36 GPT GOLD AND 6.38 GPT SILVER, INCLUDING 4.33 METRES AT 19.37 GPT GOLD AND 19.36 GPT SILVER ON THE PHILADELPHIA PROJECT, ARIZONA

Arizona Gold & Silver Inc. has received assays from the latest core hole, PC25-158, on the Philadelphia project in Arizona. This hole extends the wide zone of high-grade gold mineralization in the Perry discovery 110 metres north from hole PC25-156. Drilling is continuing with PC25-159 stepping out a further 60 m to the north.

Highlights of core hole PC25-158:

• Hole located 60 m north of the thick stockwork zone in hole PC25-157 (reported Dec. 8, 2025) and 110 m north of a high-grade intercept in PC25-156 (reported Sept. 17, 2025);
• 4.33 m at 19.37 grams per tonne gold and 19.36 g/t silver (true width: 2.60m) from 290.09 m downhole;
• 24.21 m at 6.28 g/t Au and 7.18 g/t Ag (true width: 14.53 m) from 285.85 m downhole;
• Total zone: 60.37 m at 4.36 g/t Au and 6.38 g/t Ag (true width: 36.22 m) from 279.21 m downhole.

Greg Hahn, vice-president, exploration, commented: "The Perry discovery continues to be well mineralized and extends a further 60 m north from the last reported hole. Vein textures continue to indicate we are still only at the top of the boiling zone of this impressive system. It is my objective to continue to push out the Perry strike length both to the north and south to demonstrate the scale of the mineralized structure. We know the host structure (generally known as the Arabian fault) extends for plus three kilometres. We need to determine how much of that structure, which lies entirely within Arizona Gold & Silver property, is well mineralized. The potential scale of this discovery both along strike and to depth is very significant. I look forward to seeing the intercept in hole PC25-159, currently in progress."

Core hole PC25-158

Core hole PC25-158 was collared at a 024-degree azimuth and minus-70-degree inclination. It intersected stockwork quartz-plus-calcite mineralization in andesite and conglomerate above the footwall granite. Mineralization starts at 279.21 m in andesite and continues into conglomerate at 322.37 m before encountering the hangingwall (HW) vein itself at 333.54 m. The high-grade interval occurs at the top of the mineralized structure, as encountered in hole PC25-157. It is associated with higher densities of quartz-plus-bladed-calcite veins. The shift of the high-grade intercepts into the hangingwall of the structure is similar to previous drill holes higher in the plane of the mineralized structure. The structure has always shown hangingwall and footwall veins defining the mineralized zone or corridor; the grade of those veins is what appears to vary. What is very consistent is the position and predictability of the total mineralized corridor (structure). The calcite demonstrates abundant bladed textures commonly replaced by predominantly green and yellow quartz. This suggests the company is at the top of the productive (higher-grade) boiling zone. The entire mineralized interval is summarized in the table below.

Grades have increased from PC25-157 to PC25-158, indicating a vector of increasing potential toward the company's current hole PC25-159, located 60 m further northward. That hole is approaching the target. Importantly, silver-to-gold ratios are approximately 1:1 in the high-grade zone and slightly higher than 1:1 in the surrounding stockwork zone. Low silver-to-gold ratios such as this are an indication that the company is in or near the upwelling or feeder zone that fed the vein system. Importantly, sulphur remains extremely low throughout the intercept averaging less than or equal to 0.01 per cent S, indicating there is little to no sulphide in the entire mineralized interval. Also, trace metals are very low in both the wallrock and the mineralized zone.

Mike Stark, president and chief executive officer, commented: "The Philadelphia project's deep high-grade mineralized zone continues to expand along strike, following the results from hole 156. We expect to provide an update on hole 159 next week as drilling approaches the target zone. The company remains in a strong financial position, with all outstanding warrants and options currently well in the money. Funds are being deposited steadily from the exercise of warrants."

Core hole PC25-159

Core hole PC25-159 is targeted to intersect the Perry zone 60 m north of the intercept in PC25-158 and 170 m north of the high-grade intercept in PC25-156. PC25-159 is approaching the target and is currently at 289.94 m.

Quality assurance/quality control protocols

The HQ core is delivered in its entirety to Skyline Labs in Tucson, Ariz., where it is sawn 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 are 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.
