Geophysical Survey at Philadelphia Gold-Silver Project Identifies Large Drill Target Below Flow Dome
Vancouver, February 7, 2023 - Arizona Silver Exploration Inc. (TSXV:AZS) (OTC:AZASF) is happy to announce very positive results from a test CSAMT survey on the Philadelphia gold-silver project, Arizona. The survey identified a large low resistivity layer at a depth of 100-200 metres below the top of a hydrothermally altered flow dome complex. The layer is potentially a mineralized body that extends for +500 metres east of existing mineralized drill holes. Mr. Greg Hahn, VP Exploration commented, "Building ounces in a low sulfidation epithermal system takes a lot of drilling if the target is simply the veins themselves. Grades in the veins can be spectacular but a gold inventory that includes low grade disseminated style mineralization is potentially a big win. We have intersected considerable widths of low-grade material on the flanks of the flow dome. This survey indicates an extensive target lies below the flow dome hill."
The company's geologic model had predicted a gold target area beneath the altered flow dome and immediately below a "clay cap" identified by hyperspectral analyses of core hole PC22-88, located on the flank of the altered flow dome. The CSAMT anomaly represents a sizeable bulk mining target to the east of our drill holes.
Figure 1 shows the conceptual target based upon airborne hyperspectral data and analogies with large flow dome hosted gold-silver deposits internationally. It also shows an array of drill holes that can test the target.

Figure 2 shows the hyperspectral data from core hole PC22-88 and identifies the "clay cap" and transition from montmorillonite to smectite, which is universally recognized as the 150C isotherm in geothermal systems. This is commonly referred to as the "top of the boiling zone". Gold and silver in core hole PC22-88 appears to have accumulated immediately beneath this transition in the hanging wall vein. It continues at depth in a brecciated rhyolite dike and further into the underlying footwall granite, where it diminishes.

The large low resistivity layer lies at a depth between 100-200 metres beneath the top of the flow dome and extends for +500 meters east of our fence of drill holes. This west end of this target (the Red Hills Target) can be readily tested from drill pads on the patented claims. The heart of the Red Hills target can be drilled from pads currently being permitting with the US BLM under a Plan of Operations (POO).
It should be noted that there appears to be a prominent "feeder zone" on the west side of the low resistivity anomaly. Drill hole PC22-91, the easternmost hole on the above section, intersected a prominent hydrothermal breccia (Figure 5) immediately before the hole was lost when the rods became stuck. This breccia could be the outer portion of the "feeder zone". This last box of drill core in Figure 5 assays 2 gpt gold. The objective going forward is to drill the low resistivity layer and the interpreted "feeder zone" from the BLM pads currently being permitted once permits are received.

All statements other than statements of historical fact included in this release are forward-looking statements that involve various risks and uncertainties. Forward-looking statements in this news release include statements in relation to the timing, cost and other aspects of the 2023 exploration program; the potential for development of the mineral resources; the potential mineralization and geological merits of the exploration properties; and other future plans, objectives or expectations of the Company. There can be no assurance that such statements will prove to be accurate and actual results and future events could differ materially from those anticipated in such statements. Important factors that could cause actual results to differ materially from the Company's plans or expectations include the risk that actual results of current and planned exploration activities, including the results of the Company's 2023 drilling program(s) on its properties, will not be consistent with the Company's expectations; the geology, grade and continuity of any mineral deposits and the risk of unexpected variations in mineral resources, grade and/or recovery rates; fluctuating metals prices; possibility of accidents, equipment breakdowns and delays during exploration; exploration cost overruns or unanticipated costs and expenses; uncertainties involved in the interpretation of drilling results and geological tests; availability of capital and financing required to continue the Company's future exploration programs and preparation of geological reports and studies; delays in the preparation of geological reports and studies; the metallurgical characteristics of mineralization contained within the exploration properties are yet to be fully determined; general economic, market or business conditions; competition and loss of key employees; regulatory changes and restrictions including in relation to required permits for exploration activities (including drilling permits) and environmental liability; timeliness of government or regulatory approvals; and other risks detailed herein and from time to time in the filings made by the Company with securities regulators. In connection with the forward-looking information contained in this news release, the Company has made numerous assumptions, including that the Company's 2023 programs would proceed as planned and within budget.
