Arizona Metals Announces Initial Drill Results from Sugarloaf Peak Drilling

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 hole s 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).

About the Sugarloaf Peak Project

The Sugarloaf Peak Project is located in La Paz County, Arizona, 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,

Arizona: Report for Westworld Inc.) The histo ric 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 P erson

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.

Metallurgical test work on the project by Arizona Metals indicates favorable gold recoveries in

both oxide and sulfide mineralization, as previously announced (June 1, 2021 and September 14,

2023). Cyanide bottle -roll tests on oxide material achieved gold recoveries averaging 76% with

recoveries as high as 95%; column leach testing achieved gold recoveries of up to 90%.

As a result of these initial results, the Company engaged SRK Consulting (Canada) Inc. to oversee

metallurgical test work to develop low -cost flow sheets to recover gold from the sulphide zone.

This test work on sulfide mineralization indicated gold recove ries of up to 85%. Mineralogy and

diagnostic leach tests on the samples indicate the majority of gold is present as free gold within

sulfides, primarily pyrite. As the samples tested demonstrated relatively soft material, it is likely

that whole-ore leach would be the preferred processing method for sulfide material.

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 w as completed at Arizona

Metals’ facilities located in Blythe, California, and Phoenix, Arizona. Reverse -circulation drill

samples were collected onsite and securely transported to ALS Laboratories’ (“ALS”) sample

preparation facility in Tucson, Arizona. Sa mple 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 47 other elements were analyzed by ICP methods with four -acid digestion

(ALS method ME-MS61L).

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.

Cautionary Note regarding Mineral Resource Estimates

Until mineral deposits are actually mined and processed, Mineral Resources must be considered

as estimates only. Mineral Resource Estimates that are not Mineral Reserves have not

demonstrated economic viability. The estimation of Mineral Resources is inher ently uncertain,

involves subjective judgement about many relevant factors and may be materially affected by,

among other things, environmental, permitting, legal, title, taxation, socio-political, marketing, or

other relevant risks, uncertainties, contingencies and other factors described in the Company's

public disclosure available on SEDAR+ at www.sedarplus.ca . The Inferred Mineral Resource in

this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource

and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the

Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued

exploration. The accuracy of any Mineral Resource Estimates is a function of the quantity and

quality of available data, and of the assumptions made and judgments used in engineering and

geological interpretation, which may prove to be unreliable and depend, to a certain extent, upon

the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate.

Mineral Resource Estimates may have to be re- estimated based on, among other things: (i)

fluctuations in mineral prices; (ii) results of drilling, and development; (iii) results of future test

mining and other testing; (iv) metallurgical testing and other studies; (v) results of geological and

structural modeling including block model design; (vi) proposed mining operations, including

dilution; (vii) the evaluation of future mine plans subsequent to the date of any estimates; and (viii)

the possible failure to receive required permits, licenses and other approvals. It cannot be assumed

that all or any part of a "Inferred" or "Indicated" Mineral Resource Estimate will ever be upgraded

to a higher category. The Mineral Resource Estimates disclosed in this news release were reported

using Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards for Mineral

Resources and Mineral Reserves (the "CIM Standards") in accordance with National Instrument

43-101- Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators

("NI 43-101").
