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.

Toronto, June 30, 2025 – Arizona Metals Corp. (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.

Toronto, June 24, 2025 – Arizona Metals Corp. (TSX:AMC, OTCQX:AZMCF) (the “Company” or “Arizona Metals”) is pleased to announce assay results from one drill hole in the Kay2 Zone at the Kay Project in Arizona. Drill hole KM-25-181 intersected 29.6 m @ 10.7 g/t AuEq, including 13.6 m @ 17.8 g/t AuEq (Figure 1, Table 1). Drill hole 181 is among the most gold-rich holes drilled in the deposit to date and includes the project’s third-highest gold assay from drilling: 35.8 g/t Au (756.2–757.1 m). The hole is located approximately 90 m below, and deeper in the deposit than, hole KM-24-166, the discovery hole in the Kay2 Zone. This is a significant intercept and will be incorporated in the upcoming Mineral Resource Estimate (“MRE”). Duncan Middlemiss, President and CEO of Arizona Metals, comments: “The high gold grades in the Kay2 Zone continue to indicate a robust mineralized system at Kay and illustrate additional potential for the Kay2 Zone to add value to the overall deposit. Results from hole 181 will be included in the upcoming mineral resource estimate for the Kay project, which remains on track for release this month.” To date, drilling in the Kay2 Zone has demonstrated dimensions of 100 m along strike and 160 m vertically, with consistently high gold grades throughout. The Kay2 Zone is located approximately 100 m north of previously drilled mineralization in the Kay deposit. With the completion of recent drill holes, Arizona Metals has drilled a total of 135,000 meters on the property. The Company is fully funded and on track to deliver a Mineral Resource Estimate this month, followed by a Preliminary Economic Assessment (“PEA”) in the second half of 2025, for its Kay Mine Project (the “Kay Project”) located in Yavapai County, Arizona. G Mining Services Inc. (“G Mining”) has been engaged to audit the MRE and complete the PEA. The current phase of resource drilling is complete, and the Company has mobilized the two drill rigs to the Kay North Extension target, to be followed by drilling on the North-Central and Western Targets. These areas will be drilled for the first time from newly-permitted and strategically positioned drill pads, designed to optimize targeting and access. The Company plans 10,000 m of exploration drilling at these targets with holes ranging from 300 m to 900 m in depth. The Company has chosen these high-priority targets based on analysis of geologic, geochemical, and geophysical exploration data generated to date on the project. 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-construction contractors have been chosen for the project, and the Company is preparing to mobilize crews during Q3. 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. Table 1.

Toronto, May 27, 2025 – Arizona Metals Corp. (TSX:AMC, OTCQX:AZMCF) (the “Company” or “Arizona Metals”) is pleased to announce assay results from five drill holes in the Kay2 Zone at the Kay Project in Arizona. Highlights KM-25-180: 44.5 m @ 4.0 g/t AuEq, including 9.5 m @ 9.2 g/t AuEq and 0.9 m @ 21.7 g/t AuEq (Figure 1, Table 1). The hole is ~40 m south of KM-24-166, the Kay2 discovery hole. KM-25-178: Three intervals — 18.6 m @ 2.1% CuEq, 8.4 m @ 1.9% CuEq, and 1.8 m @ 2.4 g/t AuEq (Figure 1, Table 1). This hole is ~45 m above KM-24-166. KM-25-179: Three intervals — 32.0 m @ 5.3 g/t AuEq (including 6.1 m @ 10.9 g/t AuEq), 1.5 m @ 6.2% CuEq, and 7.6 m @ 1.0% CuEq (Figure 1, Table 1). The hole is 70 m above and south of hole 166, and 70 m above hole 180. To date, drilling in the Kay2 Zone has demonstrated dimensions of ~100 m along strike and ~140 m vertically. Drilling shows good continuity in mineralization in the Kay2 Zone and adjacent mineralization in the main Kay deposit to the south. The Kay2 Zone is located approximately 100 m north of previously drilled mineralization in the Kay deposit. Duncan Middlemiss, President and CEO of Arizona Metals, commented: “We are encouraged by the latest drill results from the Kay2 Zone, which continue to demonstrate significant expansion potential. The intercepts show substantial thicknesses, consistent grades, and strong continuity—key indicators of a robust mineralized system. These results reinforce our confidence in the Kay2 Zone and support our view that these results will contribute to the overall tonnage of the Kay deposit. We believe this will be clearly reflected in the updated mineral resource estimate, which remains on track for release in the second quarter of 2025.” The Company also received approval for one additional drill pad from the Bureau of Land Management under the existing Notice of Intent to Explore permit. This pad provides additional opportunities to test the Kay North Extension target where the Kay mineralized horizon continues north from the Kay deposit. One drill hole in the Kay2 Zone, KM-25-176, encountered no significant assays (Table 1). Deep drill hole KM-25-177, targeted at the depth extension of the main Kay deposit, was lost before reaching target depth due to difficult drilling. With the completion of recent drill holes, Arizona Metals has drilled a total of 133,000 meters on the property. Table 1.

Toronto, March 3, 2025 – Arizona Metals Corp. (TSX:AMC, OTCQX:AZMCF) (the "Company" or "Arizona Metals") is pleased to announce assay results from three drill holes in the Kay2 Zone and one hole from the West target at the Kay project in Arizona. In the Kay2 Zone, drill hole KM-24-170C intersected 34.8 m @ 11.3 g/t AuEq, including 2.0 m @ 23.6 g/t AuEq and 4.0 m @ 19.1 g/t AuEq (Figure 1, Table 1). One sample in this drill hole returned 33.5 g/t Au, the third-highest gold assay on the project to date (691.1-691.7 m). The hole is located approximately 40 m below hole KM-24-166, the discovery hole in the Kay2 Zone. A second drill hole in the Kay2 Zone, KM-24-170B, intersected 4.7 m @ 1.0% CuEq (Figure 1, Table 1). The Kay2 Zone is located approximately 100 m north of previously drilled mineralization in the Kay deposit. Duncan Middlemiss, President and CEO of Arizona Metals, commented: “We are very pleased that the Kay deposit continues to demonstrate high-grade zones, and that the Kay2 Zone shows good continuity. This hole was drilled to test and confirm the continuity of mineralization in the vicinity of drill hole KM-24-166. We expect mineralization in these and other Kay2 Zone drill holes to add tonnage to the forthcoming mineral resource estimate for the Kay deposit, planned for H1 2025. Meanwhile, we continue to probe the vertical extents of both the Kay2 Zone and the main Kay deposit with deep drill holes. We are currently drilling two deep trunk holes (holes 176 and 177) below the Kay and Kay2 zones, targeting around 1150 m below surface. We will wedge these holes laterally and at successively higher elevations to determine the deeper extents of the mineralization. The results of this deeper drilling could be included in the H1-2025 mineral resource estimate.” The deep drill holes currently underway are intended to serve as trunk holes to allow multiple branch holes to further test the size of the Kay2 Zone and deeper Kay deposit mineralization. One drill hole in the Kay2 Zone, KM-24-173A, encountered no significant assays (Figure 1). An additional hole in the West target intersected the West target horizon: hole KM-24-175 intersected anomalous sulfide minerals and trace elements where expected within this mineralized horizon. With the completion of recent drill holes, Arizona Metals has drilled a total of 127,000 meters on the property. Table 1. Results of Phase 3 Drill Program at the Kay Project, Yavapai County, Arizona, announced in this news release.
