Arizona Gold drills 60.37 m of 4.36 g/t Au in Arizona

Executive Summary

• Arizona Gold & Silver Inc. reported assay results from core hole PC25-158 on its Philadelphia Project in Arizona, intersecting a 60.37-meter zone averaging 4.36 g/t Au and 6.38 g/t Ag.
• The intercept extends the high-grade Perry discovery 110 meters north from the previous hole (PC25-156) and 60 meters north from the thick stockwork zone in PC25-157.
• Drilling is actively continuing with PC25-159 targeting a further 60-meter northward extension, while management highlighted increasing grade vectors, favorable geochemical indicators, and a strong financial position supported by warrant exercises.

Key Details

• Hole PC25-158 Location & Context: Located 60 m north of PC25-157 (thick stockwork zone, reported Dec. 8, 2025) and 110 m north of PC25-156 (high-grade intercept, reported Sept. 17, 2025).
• High-Grade Interval: 4.33 m at 19.37 g/t Au and 19.36 g/t Ag (true width: 2.60 m) from 290.09 m downhole.
• Intermediate Interval: 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 Composite 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.
• Geological Setting: Intersected stockwork quartz-plus-calcite mineralization in andesite and conglomerate above the footwall granite. Mineralization begins at 279.21 m in andesite, transitions into conglomerate at 322.37 m, and encounters the hangingwall (HW) vein at 333.54 m.
• Mineralization Characteristics: High-grade interval occurs at the top of the mineralized structure, associated with high densities of quartz-plus-bladed-calcite veins. Bladed calcite textures replaced by green and yellow quartz suggest the company is at the top of the productive boiling zone.
• Geochemistry: Silver-to-gold ratios are approximately 1:1 in the high-grade zone and slightly higher in the surrounding stockwork, indicating proximity to the upwelling/feeder zone. Sulphur content is extremely low (≤0.01% S) throughout the intercept, indicating minimal to no sulphide mineralization. Trace metals are very low in both wallrock and mineralized zones.
• Drilling Update (PC25-159): Targeted 60 m north of the PC25-158 intercept and 170 m north of PC25-156. Currently drilled to 289.94 m and approaching the target zone; an update is expected next week.
• QA/QC Protocols: HQ core delivered to Skyline Labs (Tucson, AZ). Sawn per geologist-designated intervals; half crushed, pulverized, and analyzed via fire assay with AA finish for gold. Four-acid digestion and ICP used for silver/trace metals. Values >5 g/t Au rerun via fire assay with gravimetric finish. Coarse rejects preserved for metallic screen analyses and future metallurgical testing.
• Financial/Corporate Status: Company reports 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.

Notable Quotes

• Greg Hahn, Vice-President, Exploration: "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."
• Mike Stark, President and Chief Executive Officer: "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."
