SILVER RECOVERIES AVERAGE 66%, ON OXIDE AND MIXED
(OXIDE-SULPHIDE) MINERALIZATION, EXCEEDING HISTORICAL PRODUCTION
RECOVERIES
VANCOUVER, BC, July 20,
2023 /CNW/ -- Silver One Resources Inc. (TSXV: SVE)
(OTCQX: SLVRF) (FSE: BRK1) - "Silver One" or the "Company")
announces the completion of column cyanide-leach metallurgical
testing and final results from six core holes from
its Candelaria Project located in western Nevada, USA. The current silver recoveries on
oxide and mixed (oxide-sulphide) mineralization average 66%,
which exceed the historic production recoveries recorded by
previous operators NERCO and Kinross who managed open-pit, heap leach
(OP-HL) operations from 1985 to 1990 and 1993 to 1999 respectively.
Historic recoveries averaged 51% during these periods.
Gregory Crowe, President and CEO
commented: "We are very pleased with these results. The
column leach tests show an increase in silver recoveries over the
historic silver recoveries by nearly 30% when compared to those
achieved during the past production of the open-pit mine. This
improvement is largely due to the addition of High Pressure
Grinding Rollers ("HPGR") crushing prior to leaching."
The results reported belong to column cyanide-leach tests on
oxide, and mixed (oxide-sulphide) samples conducted by Kappes,
Cassiday & Associates ("KCA") in Reno, Nevada. Details of these test
results and other tests, including those on sulphide
mineralization, were reported in the Company's news releases dated
June 14, 2023 and December 13, 2022.
Current results suggest that Candelaria's existing mineral
resources may be processed by low-cost open-pit, heap-leach
methods, similar to those used in the past. However, better
silver recoveries may be achieved by using HPGR technology,
potentially improving the economics of the project. Tests completed
to date show that an addition of HPGR to the crushing circuit
increases average recoveries to 66%, which could positively impact
the operational results.
The Company has commenced further studies with the objective of
even further improving silver and gold recoveries beyond those
achieved in our recent column leach testing and HPGR crushing.
A chlorine oxidation test on mixed (oxide-sulfide) material
is underway at the KCA laboratory. Additionally, Quantitative
Evaluation of Minerals by Scanning Electron Microscope, X-Ray
Diffraction and Cation Exchange Capacity (QUEMSCAN-XRD-CEC) tests
are also being conducted at FLSmidth Inc. laboratory in
Midvale, Utah, on material from
six core samples. These tests are intended to better
determine the silver and gold mineral phases as well as the bulk
mineralogy, which will assist in the selection and optimization of
the metallurgical extraction process. Results of these tests are
expected by Q3, 2023.

About Silver One
Silver One is focused on the exploration and development of
quality silver projects. The Company owns a 100%-interest in
its flagship project, the past-producing Candelaria Mine located in
Nevada. Potential reprocessing of silver from the historic
leach pads at Candelaria provides an opportunity for possible
near-term production. Additional opportunities lie in unmined
historic resources as well as in previously identified high-grade
silver intercepts down-dip, which can potentially increase the
substantive silver mineralization along-strike from the two
past-producing open pits.
The Company has staked 636 lode claims and entered into a
Lease/Purchase Agreement to acquire five patented claims on its
Cherokee project located in Lincoln
County, Nevada, host to multiple silver-copper-gold vein
systems, traced to date for over 11 km along-strike.
Silver One holds an option to acquire a 100% interest in the
Silver Phoenix Project. The Silver Phoenix Project is a very
high-grade native silver prospect, recently permitted for drilling,
that lies within the "Arizona Silver Belt," immediately adjacent to
the prolific copper producing area of Globe, Arizona.
