Arizona Gold & Silver Reports On Continuing Philadelphia Project, Arizona Metallurgical Program - Core Drilling Program Resumes

(TheNewswire)

Vancouver, BritishColumbia, October 15, 2025 – TheNewswire - Arizona Gold & SilverInc. (TSXV: AZS) ( OTCQB:AZASF ) is verypleased announce positive column leach test progress from bulk samplesat the Philadelphia Project. New data clearly demonstrate the benefitof HPGR crushing on near surface stockwork gold zone and theamenability of this material to heap leach extraction of gold andsilver. Separately, the core drill is resuming drilling. The new holeis to test 60 metres to the north of thehigh-grade intercept of 20.43 metres grading 9.04 gpt Au and 34 gpt Agin PC25-156 (see news release dated September 17, 2025).

Highlights of theMetallurgical Work

• After 119 days of leaching the bulksample crushed by HPGR (high pressure grinding rolls) to -6.3mm (-1/4inch) has achieved 76% recovery on gold and 40% recovery onsilver.

• Leaching continues along a nearly linearleach curve (see leach curve attached).  This recovery is 16% higheron gold and 12% higher on silver than a parallel column being runusing just conventional crushing to -6.3mm (-1/4 inch).

• Recovery attained 51% on gold and 26% onsilver after only 4 days of leaching, and 60% recovery on gold and 32%recovery on silver after only 20 days of leaching.

• Recovery of bulk material HPGR crushedto -12.5mm (-1/ inch) is 61% on gold and 32% on silver in the sameperiod of time and exceeds conventionally crushed material by 16% ongold and 8% on silver.

• These data clearly demonstrate thebenefit of HPGR crushing to -6.3mm size for cyanide to access finegrained gold particles contained in microfractures within thesiliceous matrix of this near surface stockwork gold zone, and theamenability of this material to heap leach extraction of gold andsilver.

• The column leach tests will continue torun for up to 150 days total, or to whenever the leach curve rollsover and gold extraction becomes minimal.

• Kappes, Cassiday & Associateslocated in Sparks, Nevada are performing the test work. We aretargeting 80% recovery of total contained gold within 150 days at-6.3mm crush.

Greg Hahn reports: “ It is essential that a metallurgical programruns in parallel to our exploration drilling.  Drilling to date hasestablished that there are substantial volumes of stockwork materialabove the high-grade zone. That material carries 0.4-1.5 gpt gold andis particularly valuable in today’s gold price environment.  Theobjective of our metallurgical program is to demonstrate in due coursethe potential viability of a heap leach operation in tandem withunderground development of the high-grade material.

Greg continues,“The column leach tests usingHPGR crushing demonstrates the amenability of the near-surface pitablestockwork gold zone to heap leach processing. This now establishes thepath forward for evaluating this material from a mining, processing,and economic perspective.  Several other open pit heap leachoperations in the area crush to -6.3mm (-1/4”) and stack in multiplelifts up to +30 metres (100 feet). Permeability and compaction testsperformed on the bulk sample prior to column leaching demonstrate theability to stack this material to similar heights. "

QA/QC

The bulk sample was collected by Company personnel andtransported to Kappes Cassiday & Associates, where the bulk samplewas split into several sub-samples, including a head grade sample. Onesub-sample from each crushed product was subjected to compaction andpermeability tests prior to the remaining sub-samples being loadedinto columns for leaching. All data gathering and analyses areperformed by Kappes, Cassiday & Associates (“KCA”). Kappes, Cassiday & Associates is an established and highly respected service company. KCAhas provided process metallurgical services to the internationalmining industry since 1972. KCA specializes in all aspects of heapleach and cyanide processing including laboratory testing, projectfeasibility studies, engineering design, construction, and operationsmanagement. Test data from KCA are reported weekly.  Data are reviewed upon receipt byGreg Hahn, VP-Exploration, and Ing. Eugenio Iasillo, a consultant tothe Company and a process engineer located in Tucson, Arizona.

Exploration Update

The core drill has returned to the property and willcommence drilling the Perry Vein target this week. The next hole,PC25-157 is targeted to penetrate the Perry Vein 60 meters alongstrike to the north and at the same elevation as the high-gradeintercept of 20.43 metres grading 9.04 gpt Au and 34 gpt Ag reportedfrom hole PC25-156.
