ARIZONA SILVER ANNOUNCES METALLIC SCREEN ASSAYS SIGNIFICANTLY INCREASE GOLD GRADES OF HIGH-GRADE DRILL INTERCEPTS AT PHILADELPHIA PROJECT, ARIZONA HIGHEST GRADE SAMPLE INCREASES FROM 51 TO 72.5 GPT GOLD
11 July 2023 - 11:00PM
Arizona Silver Exploration
Inc. (TSXV:
AZS)
(
OTCQB:AZASF) is pleased to announce very positive
results from re-assays by the metallic screen procedure on selected
drill hole intervals on the Philadelphia epithermal gold project.
The highest-grade interval to be re-assayed showed the largest
grade increase, 42.2% (51 gpt to 72.5 gpt) gold. A total of 24
samples of both high and low-grade material were re-assayed if they
contained visible gold. The samples were all from the spring 2023
reverse circulation (“RC”) drilling campaign.
Mr. Greg Hahn, VP Exploration commented,
“Re-assaying of samples with coarse gold is a normal industry
practice to gauge if grades are being underestimated simply because
a standard 30-gram sample for fire assay can miss coarse gold that
might not be represented in a 30-gram split.. Re-assaying on 24
samples is considered statistically meaningful as we assayed both
higher and lower grade material. For all 24 samples the average
grade increased by 25.9%.”
“Going forward we will routinely re-assay
high-grade intervals and use the metallic screen technique also on
duplicate samples to resolve potential assay discrepancies when our
geologist identifies coarse gold in his logging. In due course when
Philadelphia advances into the evaluation phase much more
re-assaying will be done. In the meantime, I am delighted that our
project continues to have positive outcomes as we continue drilling
off this deposit” added Greg Hahn.

Metallic Screen and Duplicate
Re-Assays
Metallic screen assays and duplicate re-assays
were run on selected intervals from the spring 2023 RC drilling
campaign, where visible gold was identified, in order to assess the
potential for coarse gold that is not adequately represented in
standard 30-gram fire assay analyses. The results are tabulated
herein and show the high-grade intervals clearly have “coarse” gold
present in the plus 100-mesh size fraction used in the analyses.
This coarse gold fraction tends to be under-represented in a
standard 30-gram sample preparation for fire assay. The highest
grade samples show the largest amount of “coarse’ gold relative to
the lower grade samples, for which the presence of particulate gold
does not appear to be an issue. Generally, the results show a
dramatic grade increase for 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,
which originally contained a grade of 51 gpt gold, returned a grade
of 72.5 gpt gold in metallic screen analyses, a 42% increase in
grade. For that sample grades of 65 and 74.8 gpt gold were also
returned upon re-assaying the original sample using a larger
(50-gram) pulp size. The results of metallic screen analyses and
re-assaying using a larger pulp compare very favorably with one
another. This suggests re-assaying by the metallic screen procedure
of +4 gpt gold internals is recommended. Metallic screen analyses
are recommended also when discrepancies exist in standard assay and
re-assay sampling.
Overall the metallic screen analysis and
re-assaying exercise of the sample selected resulted in a 25.9%
increase in average grade of the sample suite. Metallic screen
analyses and re-assaying of low-grade samples returns grade
discrepancies of generally 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 samples submitted for metallic screen analyses.
QA/QC Program
All assaying was conducted by ALS Global, an
independent analytical laboratory. Pulverized splits are sent to
the ALS analytical facility in Vancouver, British Columbia for
analyses. All material handling is done under a strict chain of
custody protocol. Gold is determined by fire assay with an AA
finish and silver is determined by ICP-MS methods within a
31-element suite.
The Company maintains its own program of
inserting Standard Reference material in the form of standards and
blanks to the sampling stream, prior to being shipped to ALS's
preparation facility in Tucson, Arizona, in addition to the
independent QA/QC protocols of ALS Global.
