Arizona Gold & Silver Infill Drilling Intersects 90.71 Metres at 1.45 g/t Gold, Including 9.94 Metres at 5.58 g/t Gold, at the Philadelphia Project, Arizona

Deeper drilling underway

Assays pending from two holes testing the down-dip continuation of the high-grade Perry Zone

Vancouver, British Columbia – TheNewswire - September 8, 2026 - Arizona Gold & Silver Inc. (“Arizona” or the “Company”) (TSXV: AZS) (OTCQB: AZASF) is pleased to announce assay results from three infill drill holes completed at its Philadelphia Gold-Silver Project in Mohave County, Arizona (the “Philadelphia Project” or the “Project”). The holes continue to define broad zones of gold mineralization containing higher-grade internal intervals above the previously reported high-grade Perry Zone. Collectively, the results provide further evidence of vertical continuity and reinforce the potential scale of the epithermal gold-silver system.

Highlights

Infill drill holes PC26-168, PC26-170 and PC26-171B all intersect broad zones (59.2 to 90.71 metres (“m”) of mineralization that include significant high-grade intervals.

The new holes continue to delineate a broad, vertically continuous mineralized envelope above previously reported high-grade Perry Zone intersections.

With Evolution Mining’s strategic investment, drilling has expanded from day-shift operations to 24-hour operations, significantly increasing the rate of drill core production.

Assay intervals for PC26-171B, PC26-168 and PC26-170 are summarized in Table 1. Intervals are reported as drilled lengths. True thickness is estimated at approximately 60% of drilled thickness.

Notes: Intervals are presented from the broadest mineralized envelope to progressively higher-grade internal intervals. In calculating each interval, the sequence starts and ends at the applicable cutoff
