Vancouver, British Columbia, February 25, 2026 – The Newswire – Arizona Gold & Silver Inc. (“Arizona” or the “Company”) (TSXV: AZS, OTC: AZASF) (OTCQB: AZASF) announces that it has received testing of the newest core holes, PC25-159 and PC26-160, on the Philadelphia project in Arizona.
The two holes were drilled at the northern and southern boundaries of the Perry zone. Both holes crossed low gold values in previously unrecognized east-west faults. These faults vertically offset mineralization within the host Arabian fault structure. Drilling continues as the rig is currently testing the shallower portion of the Perry zone, upstream of hole PC25-156.
Drilling highlights
Hole PC25-159
28.41 meters (“m”) at 0.68 g/t gold and 6.04 g/t silver from 318.61 m downhole
included:
3.96 m at 1.66 g/t gold and 7.6 g/t silver from 318.61 m downhole
1.40 m at 2.99 g/t gold and 8.2 g/t silver from 327.42 m downhole
2.34m at 1.74g/t gold and 12.85g/t silver from 344.88 downhole
Hole PC25-160
66.39 m at 0.293 g/t gold and 1.364 g/t silver from 327.66 m downhole
included:
The actual thickness is estimated at approximately 60% of the drilled thickness.
The Perry zone is now defined as a strike length of approximately 165 meters, truncated by structural complexities relative to the east-west. Such structures appear to cross the Arabian fault which is the host structure for all known mineralization in Philadelphia. It now appears that PC25-159 has been drilled structurally above the mineralization system. The depth to the “payment zone” has not yet been determined.
A similar fallen block is suggested to the south in hole PC26-160. That hole is again interpreted to have been drilled above that part of the mineralization system.
Lex Lambeck, Senior Vice President Exploration, says: “We did not expect to drill into boundary faults to limit the strike length of the Perry zone. However, drilling continues because the zone is not fully defined and is completely open at depth. We expect good numbers in both directions.
At depth we are waiting for a drilling permit to move to new drilling platforms in the east. The permit is expected within a few months. These pads provide cost-effective settings for drilling the target zone to depth. Our model suggests the numbers will continue in that direction.
The Arabian Fault is an important control for all mineralization in Philadelphia. It continues along the strike and is largely open at depth. Importantly, it lies beneath the prominent Red Hills hydrothermal alteration cap and similar alteration areas further east.
We are pleased to initiate a geophysical program to provide drill-ready targets on the Red Hills (eastern) and northern portions of the property. That program is discussed below.”
Core holes PC25-159, PC25-160 and PC25-161
Hole 159 is located 60 meters north of the thick stockwork zone in hole PC25-158 (reported January 6, 2026) and 165 meters north of a high-grade intercept in PC25-156 (reported September 17, 2025).
Hole PC25-160 is located 60 meters south of hole PC25-156. The ore zone has become narrower and narrower, forming an aquitard for gold-bearing fluid.
Both the PC25-159 and PC25-160 drill holes suggest that they have been affected by sub-east-west fault structures that have crossed the Arbian fault in a piano key effect, with both upward and downward fault movements as observed in the 3D Discover model.
Drill hole PC25-161, drilled south of PC25-160, remains to be tested. The vein zone visually appears approximately twice as wide as observed in previous holes; however, the quartz veining is less developed and the significance of this increased width will be determined upon receipt of tests.

Core hole PC26-162
Core hole PC25-162 is being processed. It is a shallower hole than six previous holes and is designed to test the Perry zone approximately 60 meters north of PC25-136, targeting the interpreted up-dip continuation of mineralization from holes PC25-156 and 158.
Geophysical (CSAMT) program
A geophysical survey is being conducted to support ongoing geological mapping and surface sampling programs and to refine existing targets. The method used is a Controlled Source Audio Magnetotelluric (CSAMT) study. Zonge International has been contracted to complete 10 lines covering the eastern and northeastern parts of the site, as well as along the southern extension of the Arabian Fault. A pilot study had previously established the methodology’s potential effectiveness. The follow-up would use 3D geophysical inversion modeling.
The new dataset will be integrated with historical hyperspectral coverage and existing geophysical data to generate a comprehensive 3D model of the property. Notably, some of the strongest hyperspectral anomalies occur in the eastern and northeastern areas, where current CSAMT coverage is concentrated. The integrated interpretation is expected to improve target definition and prioritize potential future follow-up exercises.
QA/QC protocols
The HQ core is delivered in its entirety to Skyline Labs in Tucson, Arizona, where it is sawn in half based on the sample intervals specified by the project geologist. Half of the core is crushed, pulverized and analyzed by burning test with an AA finish on gold. A four-acid digestion and ICP analysis are used to determine silver and trace elements. All values greater than 5 gpt gold are re-run using a fire test with a gravimetric finish. The remaining core half is kept for further research. Bulk waste from crushing will be retained for metal screen analysis, if warranted, and for future metallurgical testing.
