Arizona Gold & Silver intercepts 21.79 m of 4.10 g/t Au at Philadelphia

Deeper Drilling Beneath High-Grade Perry Zone Now Underway

Vancouver, British Columbia - TheNewswire - August 13, 2026 – Arizona Gold & Silver Inc. ("Arizona" or the "Company") (TSXV: AZS) (OTCQB: AZASF) is pleased to report assay results from four diamond drill holes completed at its Philadelphia Project in Arizona. The results extend both high-grade and broad zones of gold mineralization approximately 150 metres vertically above previously reported high-grade intersections in the Perry Zone. Today’s results further demonstrate the expanding size and large scale of the gold-silver hydrothermal system along Arabian Fault system with enhanced fluid flow and mineralization development in the Perry Zone area.

With expanded U.S. Bureau of Land Management ("BLM") permits now in place, drilling has transitioned to testing the projected down-dip continuation of the high-grade intercepts in the Perry Zone beneath the hematite and argillic altered cap to the Red Hills (Figure 1).

Highlights

PC26-169: 21.79 metres grading 4.10 g/t gold and 5.8 g/t silver, within 73.46 metres grading 1.69 g/t gold and 4.4 g/t silver.

PC26-167: 15.24 metres grading 2.66 g/t gold and 5.6 g/t silver, within 66.81 metres grading 1.12 g/t gold and 4.0 g/t silver.

The four holes released today (see Table 1 below) demonstrate a broad gold mineralized zone extending approximately 150 metres vertically above the previously reported high-grade Perry Zone intersections.

The recently received expanded BLM permit provides access to 16 additional drill pads, enabling systematic testing of the Perry Zone at depth and multiple high-priority targets across the Philadelphia Project with this deeper phase of drilling underway and expected to continue through 2026.
