Arizona Metals Corp. (TSX.V:AMC, OTCQX:AZMCF) (the "Company" or "Arizona Metals") announces that metallurgical testing at its Sugarloaf Peak Project demonstrates gold recoveries averaging 76%, from surface to approximately 111 m, with oxidized zones reaching recoveries up to 95%. The Sugarloaf historic estimate of "100 million tons containing 1.5 million ounces gold"* at a grade of 0.5 g/t (Dausinger, 1983, Westworld Resources), was estimated to a depth of only approximately 70 m.

Two of the drill holes completed in the 2020 Sugarloaf Phase 1 exploration program first underwent detailed hydrothermal alteration analyses, and composite samples from these holes were then submitted to Kappes Cassiday and Associates’ facilities in Reno, Nevada for metallurgical testing. Table 1 below shows results of recently completed bottle-roll testing on holes SP-20-01 and SP-20-02. Column testing is currently underway on additional samples from these holes, with results expected in Q4 2021.
Highlights of Sugarloaf Metallurgical Testing:
Gold recoveries averaging 76%, with oxide recoveries reaching 95%
Excellent gold recoveries in both oxide and sulphide mineralization, to 111 m deep
Gold recoveries not significantly impacted by sulphide content, indicating not refractory
Drill hole SP-20-01 intersected 137 m of 0.53 g/t gold from surface, including, 99 m of 0.62 g/t gold, and 30 m of 0.90 g/t gold. Gold recoveries in this hole averaged 76%, from surface to a down-hole depth of 137 m (vertical depth of 97 m). Recoveries reached 95% in oxidized zones.
Drill hole SP-20-02 intersected 119.8 m of 0.34 g/t gold from surface, including 21.6 m of 0.44 g/t gold, and 34.8 m of 0.41 g/t gold. Gold recoveries in this hole also averaged 76%, from surface to a down-hole depth of 119.8 m (vertical depth of 111 m). Recoveries reached 94% in oxidized zones.
Marc Pais, CEO, commented "Today’s results have demonstrated the potential for excellent gold recoveries, at depths well below the historic resource estimate, which was defined down to only 70 m. We note that gold recoveries average 76%, which compares very favourably to similar heap-leach deposits currently in operation. Importantly, we observe excellent recoveries in both oxide and sulphide mineralization, indicating that the gold is not refractory. We also note that our recent drilling has shown that mineralization can continue well below the 111 m depth of this metallurgical testing, with hole SP-20-01 intersecting 38.8 m of 0.32 g/t, from 127 m to 155 m, more than twice the historic estimate depth. Based on the success of these initial tests, we plan to undertake additional metallurgical testing on deeper mineralization. Reagent consumption was also typical of rates observed in producing mines. This initial metallurgical work indicates excellent potential to recover both sulphide and oxide material in deeper mineralization, with the deposit also remaining open for expansion on strike to both the northwest and southeast."

Sugarloaf Peak Highlights
Project is 100% owned by Arizona Metals Corp. with no future payments
Located on 4,400 acres of BLM claims in mining-friendly La Paz County, Arizona
Historic estimate of "100 million tons containing 1.5 million ounces gold"* at a grade of 0.5 g/t (Dausinger, 1983, Westworld Resources).
Heap-leach, open-pit target that starts at surface and is tabular with no dip
Open for expansion at depth and on strike
Sugarloaf Peak metallurgical samples were subject to 96-hour cyanide bottle roll tests. Samples were composited from ¼ PQ-size (8.5-cm diameter) drill core in storage at the company’s facility in Ehrenberg, Arizona, and shipped by commercial carrier to Kappes, Cassiday, and Associates’ laboratory in Reno, Nevada. Samples were prepared by crushing to 80% passing 0.15 mm. One kilogram of ground sample was combined with 1.5 liters of sodium cyanide solution at a target concentration of 1 gram cyanide per liter of water in 2.5-liter bottles, and rolled for the duration of the 96-hour tests. Head and tail assays were performed by fire assay, and solution analyses were done by atomic absorption spectrometry, monitored at intervals of 2 to 24 hours. Kappes, Cassiday, and Associates is independent of Arizona Metals Corp.
Kay Mine Project, Arizona Update
Drilling at the fully-funded 75,000m Kay Mine Phase 2 program is underway with two drills turning and assays pending. The Company will provide an update on the timing of the additions of a third and fourth rig in a future release.

About Arizona Metals Corp
Arizona Metals Corp owns 100% of the Kay Mine Property in Yavapai County, which is located on a combination of patented and BLM claims totaling 1,300 acres that are not subject to any royalties. An historic estimate by Exxon Minerals in 1982 reported a "proven and probable reserve of 6.4 million short tons at a grade of 2.2% copper, 2.8 g/t gold, 3.03% zinc, and 55 g/t silver." The historic estimate at the Kay Mine was reported by Exxon Minerals in 1982. 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 be 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.
The Kay Mine is a steeply dipping VMS 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 Company also owns 100% of the Sugarloaf Peak Property, in La Paz County, which is located on 4,400 acres of BLM claims. Sugarloaf 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, 1983, Westworld Resources).

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 Quartzite, 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, 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-MS61). ALS Laboratories is independent of Arizona Metals Corp. and its Vancouver facility is 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.
