Arizona Gold & Silver refines Perry Zone model at Philadelphia Project

Feb 26, 2026

Arizona Gold and Silver CEO Mike Stark joined Steve Darling from Proactive to discuss new assay results that have enhanced the company’s structural understanding of the Perry Zone gold system at its Philadelphia project in Arizona.

Stark said the latest core holes, PC25-159 and PC26-160, were drilled along the northern and southern limits of the Perry Zone. Both holes intersected low gold grades within previously unrecognized east-west fault structures. These faults are now interpreted to vertically offset mineralization hosted within the Arabian Fault, the primary structural control for all known gold mineralization at Philadelphia.

As a result of this new data, the Perry Zone is now defined as having an approximate strike length of 165 metres, truncated by sub east-west structural complexities that appear to crosscut and displace the Arabian Fault system. The company believes hole PC25-159 was drilled structurally above the main mineralizing system, meaning the depth to the core “pay zone” remains to be determined.

Similarly, hole PC26-160 is interpreted to have encountered a down-dropped structural block to the south, suggesting it too may have been drilled above the most prospective portion of the system. Drilling is ongoing, with the current rig testing the shallower, up-dip portion of the Perry Zone above hole PC25-156. At depth, the company is awaiting a drill permit to construct new drill pads to the east. Stark said the permit is expected within months and will allow for cost-effective step-out drilling designed to test the system at depth.

Based on the evolving structural model, Arizona Gold & Silver believes gold grades are likely to persist in that direction, potentially expanding the footprint of the Perry Zone mineralization.
