ARIZONA METALS ANNOUNCES APPOINTMENT OF PAMELA SAXTON TO BOARD OF DIRECTORS; EXTENDS KAY DEPOSIT TO 1,350 M DEPTH AND CONFIRMS CONTINUITY OF KAY MINERALIZED HORIZON 280 M NORTH OF PREVIOUS DRILLING

Pamela L. Saxton has agreed to join Arizona Metals Corp.'s board of directors, with her appointment to take effect on Sept. 17, 2025.

Ms. Saxton brings more than 35 years of senior leadership and board experience in the mining and natural resources sectors. She currently serves on the boards of Bunker Hill Mining Corp. and Rare Element Resources Ltd. and has previously served as a director of Aquila Resources Inc. and Pershing Gold Corp. Her executive management experience includes serving as executive vice-president and chief financial officer of Thompson Creek Metals Company, chief financial officer of NewWest Gold Corp., and vice-president of finance for Franco-Nevada's U.S. operations. Trained as an accountant with Arthur Andersen & Co., Ms. Saxton has a proven record of financial governance, capital markets expertise and value creation within the U.S. mining sector. She holds a BSc in accounting from the University of Colorado, Boulder, and is based in Denver, Colo.

Ms. Saxton is being appointed to the board to fill a vacancy created by the departure of three of the company's independent directors. Michael Pilmer, Katherine Arnold and Rosa Espinoza have each tendered their resignations from the company's board of directors to be effective Sept. 17, 2025. Mr. Pilmer, Ms. Arnold and Ms. Espinoza were not re-elected by shareholders of the corporation at the annual meeting of shareholders of the company, which concluded on June 26, 2025, however, as permitted by Canada Business Corporations Act, each graciously agreed to remain on the board for a period following the shareholder meeting in order to facilitate an orderly transition and good corporate governance while the company searched for and identified a qualified and suitable replacement director candidate. Arizona Metals wishes to thank Mr. Pilmer, Ms. Arnold and Ms. Espinoza for their significant contributions and dedicated service to the company.

Duncan Middlemiss, president and chief executive officer of Arizona Metals, commented: "On behalf of the company and the board, I am very pleased to welcome Pam Saxton as an independent director. Pam's extensive financial leadership and board experience in the mining sector will provide valuable insight and strengthen our governance as we advance our projects. I would also like to sincerely thank Mike, Katherine and Rosa for their important contributions and commitment during their tenure with Arizona Metals."

Drill results

Arizona Metals is also pleased to announce assay results from one drill hole in the Kay2 zone and four drill holes on the Kay North Extension at the Kay project in Arizona.

In the Kay2 zone within the Kay deposit, KM-25-177A intersected 4.3 metres at 2.6 per cent copper equivalent (Table 1). This extends mineralization 280 metres below the previous deepest drill intercept on the property (KM-24-173, 2.4 m at 2.7 per cent CuEq) and brings the total downdip length of drilled mineralization on the project to approximately 1,350 m.

Drilling along the Kay North Extension target has extended drilled mineralization approximately 440 m to the north, demonstrating continuity of the Kay mineralized horizon in this direction (Table 1). Results from this drilling include 0.6 m at 4.8 per cent CuEq in KM-25-185 and 0.3 m at 3.2 per cent CuEq. Although narrow, these and other intercepts shown in Table 1 demonstrate a consistent horizon of mineralization stretching north from the Kay deposit. Additional holes in this area intersected anomalous copper, zinc and gold along this same horizon and several other parallel horizons.

Duncan Middlemiss, president and chief executive officer of the company, commented: " We are excited that these new drill results demonstrate depth potential in the Kay deposit as well as on-strike potential to the north. Both are encouraging for expansion of the Kay deposit and for our exploration efforts on targets outside the currently known Kay deposit."

Additionally, 5,000 m of reverse circulation drilling are planned at the company's Sugarloaf Peak gold project in La Paz county, Arizona. Drilling and road contractors have been chosen for the project and road crews have been mobilized. The geology team is ready and drilling is expected to begin in mid-September.

As previously stated, the company is executing on all of its previously stated goals for 2025 and looks forward to continuing the development of the company's strong assets.

About Arizona Metals Corp.

Arizona Metals owns 100 per cent of the Kay mine project in Yavapai county, which is located on 1,669 acres of patented and BLM (Bureau of Land Management) mining claims and 193 acres of private land that are not subject to any royalties. The Kay mine project is a steeply dipping VMS (volcanogenic massive sulphide) deposit that has been defined from a depth of 60 m to at least 900 m. It is open for expansion on strike and at depth.

The Kay project contains a current mineral resource estimate (MRE) of 9.28 million tonnes grading 1.39 grams per tonne Au, 27.6 g/t Ag, 0.97 per cent Cu, 0.33 per cent lead and 2.39 per cent Zn in the indicated category and 860,000 tonnes grading 1.06 g/t Au, 15.4 g/t Ag, 0.87 per cent Cu, 0.20 per cent Pb and 1.68 per cent Zn in the inferred category at a base-case cut-off grade of 1.00 per cent CuEq. CuEq MRE grades are 9.28 million tonnes at 3.18 per cent CuEq in the indicated category and 860,000 tonnes at 2.44 per cent CuEq in the inferred category.

The company also owns 100 per cent of the Sugarloaf Peak project in La Paz county, which is located on 4,400 acres of BLM claims. The Sugarloaf Peak project is a heap-leach, open-pit target and has a historic estimate of 100 million tons containing 1.5 million ounces gold at a grade of 0.5 g/t (Dausinger, N.E., 1983, phase 1 drill program and evaluation of gold-silver potential, Sugarloaf Peak project, Quartzsite, Ariz.: report for Westworld Resources Inc.).

The historic estimate at the Sugarloaf Peak project was reported by Westworld Resources in 1983. The historic estimate has not been verified as a current mineral resource. None of the key assumptions, parameters and methods used to prepare the historic estimate were reported, and no resource categories were used. Significant data compilation, redrilling and data verification may be required by a qualified person before the historic estimate can be verified and upgraded to a current mineral resource. A qualified person has not done sufficient work to classify it as a current mineral resource, and Arizona Metals is not treating the historic estimate as a current mineral resource.

Qualified person and quality assurance/quality control

All of Arizona Metals' drill sample assay results have been independently monitored through a QA/QC protocol, which includes the insertion of blind standard reference materials and blanks at regular intervals. Logging and sampling were completed at Arizona Metals' core handling facilities located in Phoenix and Black Canyon City, Ariz. Drill core was diamond sawn on site and half-drill-core samples were securely transported to ALS Laboratories' sample preparation facility in Tucson, Ariz. Sample pulps were sent to ALS's labs in Vancouver, Canada, and Reno, Nev., for analysis.

Gold content was determined by fire assay of a 30-gram charge with ICP finish (ALS method Au-AA23). Silver and 32 other elements were analyzed by ICP methods with four-acid digestion (ALS method ME-ICP61a). Overlimit samples for Au, Ag, Cu and Zn were determined by ore-grade analyses Au-GRA21, Ag-OG62, Cu-OG62 and Zn-OG62, respectively.

ALS Laboratories is independent of Arizona Metals and its Vancouver and Reno facilities are ISO 17025 accredited. ALS also performed its own internal QA/QC procedures to ensure the accuracy and integrity of results. Parameters for ALS's internal and Arizona Metals' external blind quality control samples were acceptable for the samples analyzed. Arizona Metals is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data referred to herein.
