About Arizona Metals Corp

Arizona Metals Corp. owns 100% of the Kay Mine Project in Yavapai County, Arizona, which is located on 1,669 acres of patented and BLM mining claims and 193 acres of private land that are not subject to any royalties. The Kay Mine Project contains a current mineral resource estimate (MRE) with an effective date of June 17, 2025, of 9.28 million tonnes grading 1.39 g/t Au, 27.6 g/t Ag, 0.97% Cu, 0.33% Pb and 2.39% Zn in the Indicated category, and 0.86 million tonnes grading 1.06 g/t Au, 15.4 g/t Ag, 0.87% Cu, 0.20% Pb and 1.68% Zn in the Inferred category, in each case at a base-case cut-off grade of 1.00% CuEq. Copper equivalent MRE grades are 9.28 million tonnes at 3.18% CuEq in the Indicated category and 0.86 million tonnes at 2.44% CuEq in the Inferred category. The 2026 PEA disclosed in this news release is based on the MRE and is preliminary in nature; it includes Inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the 2026 PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The Kay Mine Project is a steeply dipping VMS deposit that has been defined from a depth of 60 m to at least 900 m and remains open for expansion on strike and at depth.

The Company also owns 100% 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 short 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, Arizona: Report for Westworld 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, re-drilling 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 quality assurance/quality control ("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, Arizona. Drill core was diamond sawn on site and half drill-core samples were securely transported to ALS Laboratories' ("ALS") sample preparation facility in Tucson, Arizona. Sample pulps were sent to ALS's labs in Vancouver, Canada, and Reno, Nevada, 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). Over-limit 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 Corp. and its Vancouver and Reno facilities are ISO 17025 accredited. ALS also performed its own internal QA/QC procedures to assure the accuracy and integrity of results. Parameters for ALS' 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.

The qualified person who devised and monitored the Company's QA/QC program in respect of the underlying drill data referenced in this news release is David Smith, CPG, a qualified person as defined in NI 43-101. Mr. Smith is the Vice-President, Exploration of the Company. Mr. Smith supervised the Company's drill program and verified the data disclosed, including sampling, analytical and QA/QC data, including reviewing the reports of ALS, methodologies, results, and all procedures undertaken for quality assurance and quality control in a manner consistent with industry practice, and all matters were consistent and accurate according to his professional judgement. There were no limitations on the verification process. The scientific and technical information contained in this news release relating to the PEA, the mineral resource estimate and other technical aspects of the Kay Mine Project has been reviewed and approved by the independent Qualified Persons (as defined in NI 43-101) responsible for the relevant sections of the PEA, as identified above under "Technical Report Preparation and Qualified Persons".
