Arizona Gold drills 28.41 m of 0.68 g/t Au in Arizona

Executive Summary

• Arizona Gold & Silver reported assay results from core holes PC25-159 and PC26-160 at the Philadelphia project's Perry zone, intersecting low gold grades in previously unrecognized east-west faults that vertically offset the Arabian fault host structure.
• Drilling confirms the Perry zone is open at depth and up-dip, with structural complexities now defining a ~165m strike length. The company continues drilling to test shallower up-dip areas and awaits a permit for new eastern pads to target deeper mineralization.
• A CSAMT geophysical survey has been contracted to refine surface targets and integrate with historical data to generate a comprehensive 3D model for future drill planning.

Key Details

• Drill Intercepts (PC25-159): 28.41m @ 0.68 g/t Au, 6.04 g/t Ag from 318.61m, including 3.96m @ 1.66 g/t Au, 7.6 g/t Ag; 1.40m @ 2.99 g/t Au, 8.2 g/t Ag; 2.34m @ 1.74 g/t Au, 12.85 g/t Ag.
• Drill Intercepts (PC25-160): 66.39m @ 0.293 g/t Au, 1.364 g/t Ag from 327.66m, including 1.07m @ 1.46 g/t Au, 1.2 g/t Ag; 1.34m @ 1.87 g/t Au, 9.8 g/t Ag.
• Thickness Estimation: True thickness estimated at approximately 60% of drilled thickness.
• Structural Context: Perry zone strike length defined at ~165m, truncated by sub-east-west faults that crosscut the Arabian fault in a "piano key" effect with vertical offset. Both PC25-159 and PC25-160 interpreted as drilled above the main mineralizing system.
• Ongoing Drilling: Rig currently testing shallower portion of Perry zone up-dip of PC25-156. PC26-162 in progress, targeting up-dip continuation ~60m north of PC25-136. PC25-161 (south of PC25-160) shows visually ~2x wider vein zone but less quartz veining; awaiting assays.
• Future Drilling Plans: Awaiting drill permit for new pads to the east to target depth; expected within months. Model suggests grades will persist eastward.
• Geophysical Program: CSAMT survey underway with Zonge International (10 lines covering eastern/northeastern property and southern Arabian fault extension). Data will integrate with historical hyperspectral and legacy geophysics to generate a 3D model and prioritize drill targets.
• QA/QC Protocols: HQ core delivered to Skyline Labs (Tucson, AZ). Analyzed via fire assay with AA finish for Au; 4-acid digestion/ICP for Ag/trace metals. Values >5 g/t Au rerun via gravimetric finish. Core preserved, coarse rejects saved for metallurgical testing.

Notable Quotes

• Lex Lambeck, SVP Exploration: "We did not expect to drill into bounding faults to constrain the strike length of the Perry zone. Drilling continues, however, as the zone is not fully defined up dip and is completely open at depth. We expect to see good grades in both directions."
• Lex Lambeck: "At depth, we are awaiting a drill permit to move on to new drill pads to the east. The permit is expected within months. These pads will provide cost-effective set-ups for drilling the target zone to depth. Our model suggests grades will persist in that direction."
• Lex Lambeck: "The Arabian fault is a major control for all Philadelphia mineralization. It continues along strike and is largely open at depth. Importantly, it dips below the conspicuous Red Hills hydrothermal alteration cap and similar alteration areas further east."
• Lex Lambeck: "We are pleased to be starting a geophysical program to provide drill-ready targets on the Red Hills (eastern) and northern parts of the property."
