Discovery Silver Corp. (TSX: DSV, OTCQX: DSVSF)
(“Discovery” or the “Company”) is pleased to announce results from
Feasibility Study drill holes on its flagship Cordero silver
project (“Cordero” or “the Project”) located in Chihuahua State,
Mexico. These holes consist of reserve and resource expansion
drilling and will be incorporated in a Feasibility Study in
conjunction with a resource update planned for the first half of
2024.
Highlight intercepts from this current set of
drill holes include:
-
32 m averaging 158 g/t AgEq1 (77
g/t Ag, 0.16 g/t Au, 0.7% Pb and 1.3% Zn) from 108 m and 39
m averaging 241 g/t AgEq1 (124 g/t Ag, 0.09 g/t Au, 1.2%
Pb and 1.9% Zn) from 185 m within the reserves pit in the South
Corridor in hole C22-677.
-
36 m averaging 126 g/t AgEq1 (35 g/t Ag, 0.06 g/t
Au, 0.7% Pb and 1.7% Zn) from 481 m and 27 m averaging 133
g/t AgEq1 (25 g/t Ag, 0.06 g/t Au, 0.6% Pb and 2.2% Zn)
from 555 m in hole C22-687; these intervals were toward the bottom
and beneath the reserves pit in an area previously modelled as
waste.
-
15 m averaging 370 g/t AgEq1 (137 g/t Ag, 0.05 g/t
Au, 3.1% Pb and 3.5% Zn) from 50 m and 23 m averaging 141
g/t AgEq1 (55 g/t Ag, 0.04 g/t Au, 0.9% Pb and 1.5% Zn)
from 143 m in hole C22-671; these intervals were approximately 1.5
km northeast of the reserves pit.
Tony Makuch, CEO, states: “Our recent
Pre-Feasibility Study outlined the potential for Cordero to become
a top three primary silver mine globally based on average annual
production of 33 Moz AgEq over an 18-year mine life. Our follow up
drilling since this study demonstrates there is further growth
potential still to be realized within our upcoming Feasibility
Study. Drilling has returned a number of higher-grade intercepts
within and below the reserves pit in areas that were previously
modeled as low-grade or waste demonstrating the potential to
further lower the strip ratio through converting waste to ore
within the pit and to expand the pit at depth.
We are also excited about the district-scale
potential on our large land package. At Sanson, located 3.5 km
northeast of Cordero, and Dos Mil Diez, 1.5 km to the southeast, we
have identified large chargeability anomalies with similar
intensity to the ore body at Cordero. Surface mapping at both
targets has established intense alteration with anomalous levels of
pathfinder elements. We look forward to the commencement of
drilling at these targets over the coming months.”
DRILL RESULTS:
This current set of Feasibility Study drilling
consists of 30 drill holes and was focused on two key areas: 1)
expansion of reserves within and beneath the Pre-Feasibility Study
open pit and 2) upgrading and expansion of the resource in the far
northeast of the deposit. Supporting maps and sections, drill hole
locations and full assay results can be found here: Plan map,
sections & assays. A PDF of this release with supporting maps
and sections included as appendices can be found here: Press
release with plan map & sections.
Reserves Expansion Drilling
Drilling has been focused on expanding reserves
through the conversion of waste to ore within the reserves pit and
through the expansion at depth of the reserves pit. In the
northeast of the deposit, C22-675 intercepted 83.7 m of 83 g/t
AgEq1 at the bottom of the reserves pit and 38.2 m of 64 g/t AgEq1
approximately 50 m below the reserves pit. Also in the northeast,
C22-683 intercepted 27.6 m of 148 g/t AgEq1 approximately 100 m
below the reserves pit. All three intervals were within areas
predominantly modelled as waste.
In the central part of the deposit, C22-687
intercepted 35.6m of 126 g/t AgEq1 toward the bottom of the
reserves pit and 27.4 m of 133 g/t AgEq1 directly beneath the pit
in areas modelled as waste. In the southwest of the deposit,
C22-677 intercepted 31.7m of 158 g/t AgEq1 from 107.8 m and 38.5 m
of 241 g/t AgEq1 from 184.9 m. Both intervals were within the
reserves pit in zones previously modeled as low to medium grade
highlighting the potential to increase the grade profile in this
part of the deposit.

Far Northeast Drilling
Drilling in 2022 outlined low grade
mineralization with a number of discrete high-grade zones in the
far northeast of the deposit, more than 1 km beyond the limits of
the reserves pit. Most of this mineralization is within 100 m of
surface and is included within the resource pit constraint as part
of the January 2023 resource update. 15 follow up drill holes have
been completed testing the lateral depth and strike extent of
mineralization within this zone.
Hole C22-671 returned intervals of 14.8 m of 370
AgEq1 from 49.7 m and 23.1 m of 141 AgEq1 from 142.7 m in hole
C22-671. This hole was drilled on section approximately 60 m to the
southeast of C22-611 that returned 36.4 m of 94 AgEq1 from 142.7 m
and 14.6 m of 124 AgEq1 from 186.8 m representing the potential
lateral expansion of this zone. C22-662 intercepted 10.4m of 94
AgEq1 from 273.0 m. This represents the potential lateral expansion
of the mineralization intercepted in C22-609 drilled on section
approximately 60 m to the northwest that returned 33.1 m of 150
AgEq1 from 233.7 m and 17.7 m of 115 AgEq1 from 198.2 m (see July
13, 2022, press release).
The follow up drilling in the far northeast
confirms the presence of a broad mineralized fracture system in the
area. The orientation of mineralization does not appear to be
consistent with the dominant northeast orientation evident in the
main part of the Cordero deposit. A more detailed review of
fracture orientation along with further drilling is required to
develop a better understanding of the main controls of
mineralization in this part of the deposit.

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 39,000 m (131
holes) as part of its Feasibility Study drill program (since the
data cut-off for the PFS study). Feasibility study drilling
consists of engineering drilling, resource upgrade drilling and
drilling targeting the expansion of the PFS open pit. An additional
12,000 m is still to be drilled in this drill program and will be
ongoing in the first half of this year.
Significant target generation work on the
Company’s large, highly-prospective land package was completed in
2022. In addition to mapping and sampling work, 125 line-km’s of
induced polarization (IP) surveys were completed during 2022 and
early 2023 at the Molino de Viento, La Perla, Sanson, Dos Mil Diez
targets and at the site of the proposed tailings storage facility.
The surveys identified large chargeability anomalies at Molino de
Viento and in the eastern portion of Sanson. These anomalies
reported a similar level of chargeability intensity to those in the
main Cordero resource area. Drill testing of these anomalies
is scheduled to commence in the middle of the year with initial
drilling focused on Sanson. Currently, 9,000m of drilling is
planned for property wide drilling in 2023. This program may be
expanded depending on the results of the initial drilling.
About Discovery
Discovery’s flagship project is its 100%-owned
Cordero project, one of the world’s largest silver deposits. The
PFS published in February 2023 demonstrates that Cordero has the
potential to be developed into a highly capital-efficient mine that
offers the combination of margin, size, and scalability. 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$40 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.
