Arizona Silver Exploration Provides Results on Metallurgical Tests ranging from 94.40%
to 99.50% recovery from the Philadelphia Project.
Vancouver, British Columbia, July 29, 2020 – Arizona Silver Exploration Inc. (TSXV: AZS) (OTCQB:
AZASF) is providing an update on metallurgical test results from our 100% owned Philadelphia property.
The Company submitted eight bulk samples from the recently completed reverse circulation drilling program to
evaluate the potential for recovery of coarse gold by gravity separation and the amenability of gold not recovered
by gravity methods to cyanidation.
The results are summarized in the table below and demonstrate that +27% to 65.5% of the gold in the drill cuttings
is coarse and is recoverable by gravity methods, confirming the observations of visible gold in cuttings during
drilling. The gravity tails were subject to cyanidation bottle roll tests, w hich demonstrate that the majority of the
gold remaining in the gravity tails is recoverable by cyanidation. Total recoveries by gravity and cyanidation are
consistently in the +98% to +99% range.

The Company will mobilize a core rig to the Philadelphia property after it has completed drilling our 100% owned
Ramsey property, an historic silver produc er. The program will test the high -grade zone on the west side of the
Philadelphia vein system encountered in RC and core drilling previously and announced on November 13

Philadelphia and look forward to drilling the west side again.
QA/QC Program for the Metallurgical Test Program
The bulk samples of drill cuttings were shipped under stric t chain of custody from Sk yline Laboratories in Tucson,
Arizona to McClelland Laboratories in Sparks, Nevada. McClelland Labs is an IAS Accredited full service
metallurgical testing facility with long-established exp ertise and capabilities in metallurgy of precious metals
materials. Samples were treated separately and each pulverized to -100 mesh and subjected to gravity separation in a
Knelson concentrator. Concentrates were analyzed to extinction to determine the a mount of gold contained in the
gravity concentrate. Tails from the gravity concentration process were subject to bottle roll cyanidation tests for up to
72 hours duration. Effectively all gold was dissolved in 24 to 48 hours. Solutions were analyzed for gold to calculate
the amount of gold extracted from each sample. Tails were dried and analyzed to determine the amount of gold
unrecovered by cyanidation. Calculated head grades were determined by combining the gold recovered by gravity
concentration with the gold recovered by cyanidation and the remaining gold content of the cyanidation tails.
