Toronto, December 2, 2025 – Arizona Metals Corp. (TSX:AMC, OTCQX:AZMCF) (the “ Company ” or “ Arizona Metals ”) is pleased to announce the first round of results from its 2025 reverse-circulation drill program on the Sugarloaf Peak project in Arizona. Highlights of the drilling include: SP-25-09: 195.1 m @ 0.31 g/t Au, including 25.9 m @ 0.61 g/t Au. This was an infill hole in the center of the deposit, demonstrating excellent continuity and mineralization from surface. SP-25-11: 109.7 m @ 0.31 g/t Au, including 16.8 m @ 0.49 g/t Au. This was an infill hole in a 300 x 300 m gap in the north-central part of the deposit; together with holes 12 and 13, this confirms good continuity of mineralization in this area, adding significant volume to the deposit. SP-25-05: 134.1 m @ 0.29 g/t Au and 70.1 m @ 0.32 g/t Au. This was a twin of historic hole WW-9 in the central portion of the deposit. SP-25-12: 73.2 m @ 0.27 g/t Au and 41.1 m @ 0.30 g/t Au. This was an infill hole in a 300 x 300 m gap in the north-central part of the deposit. Mineralization was intersected in all nine drill holes assayed to date in an area covering 900 m along the strike of mineralization and 800 m in width. These initial drill results are consistent with the drill program goals, as these results demonstrate mineralization in all infill holes and extend mineralization in all step-out holes received to date. In several drill holes, mineralization was also extended at a depth below previous drilling by 40-75 m. Assay results from the remaining 16 drill holes are pending. The total drilling to date on the project, in 2025, comprises 5,186 m drilled in 25 reverse-circulation drill holes. Duncan Middlemiss, President and CEO of Arizona Metals commented: “We are pleased to confirm the expansion potential at Sugarloaf Peak. This is a very large mineralized system that our drilling has expanded, not only laterally but within the deposit. In particular, our drilling confirmed excellent continuity of mineralization, a real benefit in a bulk-mining open-pit scenario. We intend to continue to explore Sugarloaf Peak and test its size within the deposit, at depth, and along strike.” Additional drill results are as follows: SP-25-06: 21.3 m @ 0.20 g/t Au and 10.7 m @ 0.37 g/t Au. This hole extends mineralization 95 m southwest of previous drilling, increasing the width of mineralization. SP-25-07: 35.1 m @ 0.32 g/t Au. Infill hole in a 260-m gap along the southwestern edge of the deposit, confirming good continuity of mineralization in this area. SP-25-08: 15.2 m @ 0.22 g/t Au. Stepout hole 110 m southwest of hole 7. Together with hole 7, this extends mineralization almost 200 m southwest in this portion of the deposit. SP-25-10: 9.1 m @ 0.25 g/t Au. Stepout hole to the 135 m to the west of previous drilling, warranting follow-up drilling in this area. SP-25-13: Four intervals, including 35.1 m @ 0.40 g/t Au and 30.5 m @ 0.27 g/t Au. Infill hole in a 300 x 300 m gap in the north-central part of the deposit. This hole returned the highest individual assay in this round of drilling so far, 6.64 g/t Au (56.4-57.9 m). Table 1. Results of drill program at the Sugarloaf Peak Project, Yavapai County, Arizona announced in this news release, including the depth of oxidized mineralization encountered in each hole.

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 m @ 2.6% CuEq (Table 1, Figure 1). This extends mineralization 280 m below the previous deepest drill intercept on the property (KM-24-173, 2.4 m @ 2.7% CuEq), and brings the total down-dip 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, Figure 2, Figure 3). Results from this drilling include 0.6 m @ 4.8% CuEq in KM-25-185 and 0.3 m @ 3.2% 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 Cu, Zn, and Au along this same horizon and several other parallel horizons. Duncan Middlemiss, President and CEO of the Company, comments: “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 is planned at the Company’s Sugarloaf Peak Gold Project (the “Sugarloaf Peak 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.

(TSX:AMC, OTCQX:AZMCF) (the “Company” or “Arizona Metals”) is pleased to announce an initial Mineral Resource Estimate (“MRE”) for its 100% owned Kay Mine Project (the “Kay Project”) located in Yavapai County, Arizona. Highlights of the Kay Project MRE are as follows:  The underground MRE includes 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, at a base-case cut-off grade of 1.00% CuEq. Copper equivalent MRE grades are 9.28 million tonnes @ 3.18% CuEq in the Indicated category and 0.86 million tonnes @ 2.44% CuEq in the Inferred category. Quality Asset: High grade, with good geometry and continuity suitable for bulk underground mining methods. Camp Potential: The initial MRE sits within less than 5% of the 10-km long strike of folded prospective host rocks in the Kay Project. Infill Potential: This initial MRE has clear potential to expand between existing drill holes within the deposit, and to upgrade Inferred resource. Expansion Potential: The deposit remains open for expansion beyond this initial MRE both along strike and at depth. Continued Advancement: Following the completion of additional metallurgical testwork, a preliminary economic assessment (“PEA”) is planned for release in the second half of 2025. The Company is delivering and executing on all of its previously stated goals for 2025 and looks forward to continuing the development of the Company’s strong assets. Duncan Middlemiss, President and CEO of Arizona Metals, comments: “The release of our initial Mineral Resource Estimate marks a major milestone for Arizona Metals and validates not only the scale, but more importantly, the quality of the Kay Project. With over 650 million pounds of copper equivalent in the Indicated category alone—and with the deposit remaining open in multiple directions—we see significant opportunity for expansion through continued drilling. We believe this resource represents just the beginning. With a strong treasury and a PEA on track for release later this year, we’re excited to advance the Kay Project toward becoming one of the top undeveloped VMS projects in the U.S.” Table 1.
