Deeper Drilling Underway at High-Grade Perry Zone, Arizona Gold & Silver Reports Extended Mineralization
Vancouver, British Columbia — August 13, 2026 — Leads & Copy — Arizona Gold & Silver Inc. announced today that deeper drilling has commenced beneath its high-grade Perry Zone at the Philadelphia Project in Arizona, following the receipt of expanded U.S. Bureau of Land Management permits. The current drilling phase aims to test the projected down-dip continuation of high-grade gold and silver mineralization within the Perry Zone, situated beneath the hematite and argillic altered cap of Red Hills.
Assay results from four recently completed diamond drill holes have extended both high-grade and broad zones of gold mineralization approximately 150 metres vertically above previously reported intersections in the Perry Zone. These findings further indicate the expanding scale and significant hydrothermal system along the Arabian Fault system, characterized by enhanced fluid flow and mineralization development in the Perry Zone.
Key highlights from the latest results include Hole PC26-169, which returned 21.79 metres grading 4.10 g/t gold and 5.8 g/t silver, including a broader interval of 73.46 metres grading 1.69 g/t gold and 4.4 g/t silver. Additionally, Hole PC26-167 yielded 15.24 metres grading 2.66 g/t gold and 5.6 g/t silver, within an even wider interval of 66.81 metres grading 1.12 g/t gold and 4.0 g/t silver.
The four holes reported—PC26-165, PC26-166, PC26-167, and PC26-169—were primarily designed to test the up-dip extensions of mineralization within the Perry Zone and to further delineate the broader mineralized envelope above the system’s high-grade core. These results demonstrate a substantial gold mineralized zone extending approximately 150 metres vertically above earlier reported high-grade Perry Zone intersections.
Dr. Lex Lambeck, Senior Vice President Exploration for Arizona Gold and Silver, stated that these results reinforce the company’s geological model, confirming broad gold mineralization within the Perry Zone and bolstering confidence in the system’s geometry and continuity. He noted that drilling has now progressed below previously identified higher-grade intersections, targeting the projected down-dip continuation of the Perry Zone and a coincident Controlled-Source Audio-frequency Magnetotellurics (CSAMT) geophysical target beneath Red Hills. This deeper phase of exploration is seen as a crucial step in expanding the high-grade core of the Perry Zone and validating the geological model.
The recently expanded BLM permit grants access to 16 additional drill pads, facilitating a systematic approach to testing the Perry Zone at depth and multiple high-priority targets across the Philadelphia Project. This deeper drilling phase is expected to continue through 2026. Exploration is also advancing on hyperspectral anomalies in the Eastern and Northeastern areas, as the company assesses the district-scale potential of the Philadelphia low-sulfidation epithermal gold system.
Drilling of Hole PC26-169, located approximately 30 metres north of PC25-154, intersected mineralized rhyolite and andesite quartz breccia and calcite breccia. Significant results include 21.79 metres at 4.10 g/t Au and 5.8 g/t Ag, within 37.34 metres at 3.10 g/t Au and 7.1 g/t Ag, and within 73.46 metres at 1.69 g/t Au and 4.4 g/t Ag. Mineralization is linked to strong andesite-hosted quartz-calcite veining and brecciation, occurring above the interpreted boiling horizon in the upper hydrothermal system.
Hole PC26-165, drilled approximately 90 metres above PC23-111, tested the up-dip continuation of mineralization and intersected a broad mineralized corridor hosted by quartz-rich rhyolite breccia and calcite breccia. Significant results include 0.98 metres at 10.19 g/t Au and 8.7 g/t Ag, within 3.11 metres at 3.34 g/t Au and 12.7 g/t Ag, and 6.95 metres at 2.07 g/t Au and 2.9 g/t Ag, within 62.27 metres at 0.70 g/t Au and 2.0 g/t Ag. Mineralization is stratigraphically above the interpreted boiling horizon, showing progressively stronger calcite veining with depth.
Hole PC26-167, drilled approximately 90 metres above PC25-156, tested the up-dip continuation of the Perry Zone, intersecting a broad zone of mineralization within the upper portion of the interpreted hydrothermal upwelling system. Significant results include 15.24 metres at 2.66 g/t Au and 5.6 g/t Ag, within 28.35 metres at 2.19 g/t Au and 7.9 g/t Ag, and within 66.81 metres at 1.12 g/t Au and 4.0 g/t Ag. Alteration, brecciation, and vein textures suggest the drilling remains within the upper part of the hydrothermal system, above the high-grade section of the Perry Zone.
Hole PC26-166, drilled approximately 20 metres below PC25-154, tested the up-dip continuation of the Perry Zone, intersecting broad gold mineralization within the upper hydrothermal system. Significant results include 1.37 metres at 3.02 g/t Au and 6.6 g/t Ag, within 23.64 metres at 1.42 g/t Au and 6.8 g/t Ag, and within 32.95 metres at 1.11 g/t Au and 6.0 g/t Ag.
The Company’s QA/QC protocols include processing core samples at Skyline Labs in Tucson, Arizona, with gold analyzed by fire assay and silver and multi-element analysis by ICP-MS. A rigorous QA/QC program, including the insertion of certified standards and blanks, is maintained. Dr. Lex Lambeck, SVP Exploration for Arizona Gold and Silver, is the Qualified Person for this release, having reviewed the drill core and assay data and approved the technical content.
