Discovery Silver Corp. (TSX-V: DSV, OTCQX: DSVSF)
(“Discovery” or the “Company”) is pleased to announce results from
the first 15 Feasibility Study drill holes on its flagship Cordero
silver project (“Cordero” or “the Project”) located in Chihuahua
State, Mexico. These holes consisted of upgrade and expansion
drilling of the proposed open pit and were drilled subsequent to
the data cut-off date for the Pre-Feasibility Study (“PFS”). The
Pre-Feasibility Study is progressing well and remains on track to
be delivered in early 2023.
Highlight intercepts from this current set of
drill holes include:
-
77 m averaging 126 g/t AgEq1 (46
g/t Ag, 0.08 g/t Au, 0.7% Pb and 1.4% Zn) from 218 m and 22
m averaging 265 g/t AgEq1 (83 g/t Ag, 0.10 g/t Au, 1.8% Pb
and 3.2% Zn) from 374 m in hole C22-656.
-
96 m averaging 124 g/t AgEq1 (33 g/t Ag, 0.03 g/t
Au, 0.7% Pb and 1.8% Zn) from 464 m including 36 m
averaging 190 g/t AgEq1 (44 g/t Ag, 0.04 g/t Au, 0.9% Pb
and 3.1% Zn) in hole C22-654.
-
43 m averaging 179 g/t AgEq1 (62 g/t Ag, 0.11 g/t
Au, 1.4% Pb and 1.7% Zn) from 228 m in hole C22-648.
-
52 m averaging 139 g/t AgEq1 (49 g/t Ag, 0.07 g/t
Au, 0.8% Pb and 1.7% Zn) from 224 m in hole C22-653.
Tony Makuch, Interim CEO, states: “Results from
our first set of drill holes to increase the confidence level of
the resource model continues to demonstrate the excellent
continuity of mineralization within the open pit at Cordero and
supports the mineral resource estimation. Drilling on the margins
of the pit also outlines the opportunity to expand the size of the
pit laterally and at depth as we proactively target value-creation
opportunities.
Meanwhile we continue to make excellent progress
on our Pre-Feasibility Study. Geotechnical evaluation work has
confirmed favourable ground conditions of the proposed locations of
key infrastructure, including the rock storage facility and the
tailings storage facility. Mine design has been focused on the
optimisation of mine phasing including targeting a reduction in the
volume of pre-strip during the development period. The process
design has been improved and incorporates a conventional flowsheet
with silver production and operating costs expected to benefit from
better metallurgical recoveries and mill throughput rates that are
approximately 25% higher than what was assumed in the PEA. Other
scope areas are progressing well and we remain on schedule to
deliver this major milestone in early 2023.”
DRILL RESULTS:
This initial set of Feasibility Study drill
holes was focused on two key areas: 1) further upgrading the
resource classification within the PEA pit and 2) expanding and
upgrading resource blocks between the PEA pit and the Resource
constraining pit shells. Detailed drill highlights from the holes
in this release are provided in the tables below. Supporting maps
and sections, drill hole locations and full assay results can be

In the South Corridor, hole C22-654 intercepted
95.7 m of 124 g/t AgEq1 on the margins of the PEA pit and at a
vertical depth of approximately 450 m. Hole C22-656, drilled to
upgrade the resource in the central part of the South Corridor,
returned a number of strong intervals including 77.1 m of 126 g/t
AgEq1 from 131.1 m and 21.7 m of 265 g/t AgEq1 from 374.3 m.
In the North Corridor, hole C22-648 intercepted
27.4 m of 86 g/t AgEq1 from 166.2 m and 42.6 m of 179 g/t AgEq1
from 228.3 m, confirming the continuity of higher-grade
mineralization within the core of the PEA pit. Hole C22-647,
drilled to improve the data density on the western edge of the pit,
returned 25.6 m of 99 g/t AgEq1 from 174.1 m and 18.7m of 147 g/t
AgEq1 from 264.8 m. Both intervals were outside of the PEA pit
limit demonstrating the potential to laterally expand future pit
extents.

1All results in this news release are rounded.
Assays are uncut and undiluted. Widths are drilled widths, not true
widths, as a full interpretation of the actual orientation of
mineralization is not complete. As a guideline, intervals with
disseminated mineralization were chosen based on a 25 g/t AgEq
cutoff with no more than 10 m of dilution. AgEq calculations are
used as the basis for total metal content calculations given Ag is
the dominant metal constituent as a percentage of AgEq value in
approximately 70% of the Company’s mineralized intercepts. AgEq
calculations for reported drill results are based on USD $22.00/oz
Ag, $1,600/oz Au, $1.00/lb Pb, $1.20/lb Zn. The calculations assume
100% metallurgical recovery and are indicative of gross in-situ
metal value at the indicated metal prices. Refer to Technical Notes
below for metallurgical recoveries assumed in the 2021 PEA
completed on Cordero.
DRILL PROGRAM UPDATE:
The Company has now completed approximately
17,000 m (52 holes) as part of its Feasibility Study drill program.
Feasibility study drilling will consist of engineering drilling,
resource upgrade drilling and drilling targeting the expansion of
the PFS open pit. The total metres to be drilled in the feasibility
study drill program will be finalised following the completion of
the PFS scheduled for early 2023. Total metres supporting the PFS
is summarized below:

About Discovery
Discovery’s flagship project is its 100%-owned
Cordero project, one of the world’s largest silver deposits. The
PEA completed in November 2021 demonstrates that Cordero has the
potential to be developed into a highly capital efficient mine that
offers the combination of margin, size and scaleability. Cordero is
located close to infrastructure in a prolific mining belt in
Chihuahua State, Mexico. Continued exploration and project
development at Cordero is supported by a strong balance sheet with
cash of approximately C$55 million.

Sample analysis and QA/QC
ProgramThe true width of the veins is estimated to be
approximately 70% of the drilled width. Assays are uncut except
where indicated. All core assays are from HQ drill core unless
stated otherwise. Drill core is logged and sampled in a secure core
storage facility located at the project site 40km north of the city
of Parral. Core samples from the program are cut in half, using a
diamond cutting saw, and are sent to ALS Geochemistry-Mexico for
preparation in Chihuahua City, Mexico, and subsequently pulps are
sent to ALS Vancouver, Canada, which is an accredited mineral
analysis laboratory, for analysis. All samples are prepared using a
method whereby the entire sample is crushed to 70% passing -2mm, a
split of 250g is taken and pulverized to better than 85% passing 75
microns. Samples are analyzed for gold using standard Fire
Assay-AAS techniques (Au-AA24) from a 50g pulp. Over limits are
analyzed by fire assay and gravimetric finish. Samples are also
analyzed using thirty three-element inductively coupled plasma
method (“ME-ICP61”). Over limit sample values are re-assayed for:
(1) values of zinc > 1%; (2) values of lead > 1%; and (3)
values of silver > 100 g/t. Samples are re-assayed using the
ME-OG62 (high-grade material ICP-AES) analytical package. For
values of silver greater than 1,500 g/t, samples are re-assayed
using the Ag-CON01 analytical method, a standard 30 g fire assay
with gravimetric finish. Certified standards and blanks are
routinely inserted into all sample shipments to ensure integrity of
the assay process. Selected samples are chosen for duplicate assay
from the coarse reject and pulps of the original sample. No QAQC
issues were noted with the results reported herein.

TECHNICAL NOTES & FORWARD-LOOKING
STATEMENTS:
The most recent technical report for the Cordero
Project is the 2021 Preliminary Economic Assessment (PEA). The PEA
was completed by Ausenco Engineering Canada Inc. with support from
AGP Mining Consultants Inc. and Knight Piésold and Co. (USA). The
full technical report supporting the PEA is available on
Discovery’s website and on SEDAR under Discovery Silver Corp.
The PEA assumed average life-of-mine recovery
assumptions for sulphide material of 84% for Ag, 19% for Au, 86%
for Pb and 85% for Zn. The PEA assumed oxide recovery assumptions
of 56% for Ag and 63% for Au for crushed feed and 36% for Ag and
35% for Au for uncrushed ROM feed.
