Highest Grade Sample Increases f rom 51 t o72.5 g pt Gold
Vancouver, British Columbia – TheNewswire - July 11, 2023 – Arizona Silver ExplorationInc. (TSXV: AZS ) ( OTC:AZASF ) is pleased toannounce very positive results from re-assays by the metallic screenprocedure on selected drill hole intervals on the Philadelphiaepithermal gold project. The highest-grade interval to be re-assayedshowed the largest grade increase, 42.2% (51 gpt to 72.5 gpt) gold. Atotal of 24 samples of both high and low-grade material werere-assayed if they contained visible gold. The samples were all fromthe spring 2023 reverse circulation (“RC”) drilling campaign.
Mr. Greg Hahn, VP Exploration commented,“ Re-assaying of sampleswith coarse gold is a normal industry practice to gauge if grades arebeing underestimated simply because a standard 30-gram sample for fireassay can miss coarse gold that might not be represented in a 30-gramsplit.. Re-assaying on 24 samples is considered statisticallymeaningful as we assayed both higher and lower grade material. For all24 samples the average grade increased by 25.9%.”
“Going forward we will routinelyre-assay high-grade intervals and use the metallic screen techniquealso on duplicate samples to resolve potential assay discrepancieswhen our geologist identifies coarse gold in his logging. In duecourse when Philadelphia advances into the evaluation phase much morere-assaying will be done. In the meantime, I am delighted that ourproject continues to have positive outcomes as we continue drillingoff this deposit” added Greg Hahn .

Metallic Screen and DuplicateRe-Assays
Metallic screen assays and duplicate re-assays were runon selected intervals from the spring 2023 RC drilling campaign, wherevisible gold was identified, in order to assess the potential forcoarse gold that is not adequately represented in standard 30-gramfire assay analyses. The results are tabulated herein and show thehigh-grade intervals clearly have “coarse” gold present in theplus 100-mesh size fraction used in the analyses. This coarse goldfraction tends to be under-represented in a standard 30-gram samplepreparation for fire assay. The highest grade samples show thelargest amount of “coarse’ gold relative to the lower gradesamples, for which the presence of particulate gold does not appear tobe an issue. Generally, the results show a dramatic grade increasefor samples with initial grades of +4-5 grammes per tonne (“gpt”)gold, although that is not always the case.
The highest grade sample in drill hole PRC23-97, whichoriginally contained a grade of 51 gpt gold, returned a grade of 72.5gpt gold in metallic screen analyses, a 42% increase in grade. Forthat sample grades of 65 and 74.8 gpt gold were also returned uponre-assaying the original sample using a larger (50-gram) pulp size. The results of metallic screen analyses and re-assaying using alarger pulp compare very favorably with one another. This suggestsre-assaying by the metallic screen procedure of +4 gpt gold internalsis recommended. Metallic screen analyses are recommended also whendiscrepancies exist in standard assay and re-assay sampling.
Overall the metallic screen analysis and re-assayingexercise of the sample selected resulted in a 25.9% increase inaverage grade of the sample suite. Metallic screen analyses andre-assaying of low-grade samples returns grade discrepancies ofgenerally less than 0.5 gpt gold, and mostly less than 0.1 gpt gold,suggesting coarse gold is not an issue in the lower grade samplessubmitted for metallic screen analyses.
QA/QC Program
All assaying was conducted by ALS Global, anindependent analytical laboratory. Pulverized splits are sent to theALS analytical facility in Vancouver, British Columbia for analyses.All material handling is done under a strict chain of custodyprotocol. Gold is determined by fire assay with an AA finish andsilver is determined by ICP-MS methods within a 31-element suite.
The Company maintains its own program of insertingStandard Reference material in the form of standards and blanks to thesampling stream, prior to being shipped to ALS's preparation facilityin Tucson, Arizona, in addition to the independent QA/QC protocols ofALS Global.
