VANCOUVER, BC, Jan. 24, 2022 /PRNewswire/ - Silvercorp Metals
Inc. ("Silvercorp" or the "Company") (TSX: SVM) (NYSE American:
SVM) is pleased to report additional high-grade intercepts from its
2021 exploration program at the SGX mine. Extensive exploration
drilling and tunneling are ongoing at the SGX mine and all other
mines in the Ying Mining District, Henan
Province, China.
From July 1 to December 31, 2021,
52,634 metres ("m") from a total of 327 diamond drill holes,
including 272 underground holes and 55 surface holes, were
completed at the SGX mine. Assay results for 209 holes have been
received, with 102 holes intercepting mineralization. The Company
also received assay results for 33 holes pending from the
previous drilling program at the SGX mine from October 1, 2020 to June
30, 2021 disclosed in the Company's news release dated
July 6, 2021. Currently, there are 19
rigs drilling at the SGX mine.
The strategy of the drilling program is fourfold: 1) drill above
or beneath the stopes that were previously mined but stopped due to
more variation in grades, thickness and attitudes of the vein
structures than previously modeled; 2) drill for silver-lead-zinc
veins in the resource area at higher elevations closer to surface
where there are limited drill holes from previous drilling
programs; 3) drill for gold-silver veins in the resource area that
were not prioritized in previous drilling programs; and 4) drill
step-outs to the east of the resource area to confirm the
continuity of the newly discovered gold-silver veins.
Drilling Above or Beneath Previously Mined Stopes and Near
Surface Silver-Lead-Zinc Veins within the Resource Area
Most holes drilled during this period targeted blocks of known
silver-lead-zinc veins in production areas that were previously
missed due to limited drilling or tunneling, changes in the strikes
and dips, and/or pinch-swelling of the pay-zones in the veins. The
high-grade intercepts are mainly associated with the
northwest-dipping S2 series, S6 series, S7 series, S8 series, S14
series, S18 series, S19 series, S21 series, east-dipping S31, S28,
S29, and S32 veins, which have resulted in a significant amount of
upgraded resources. Since access tunnels are already in place, any
high-grade mineralization discovered can quickly be converted to
reserves and mined.
Highlights of the high-grade silver-lead-zinc intercepts at the
SGX mine:
- Hole ZK02AS6E1007 intersected a 3.19 m interval (1.35
m true width) of vein S31 grading 2,532 grams per tonne
("g/t') silver ("Ag"), 0.69% lead ("Pb"), 14.38% zinc ("Zn"), 0.05
g/t gold ("Au"), and 0.12% copper ("Cu") from 58.35 m depth, at an elevation of 372 m;
- Hole ZK12S7001 intersected a 2.02
m interval (1.65 m true width)
of vein S7a1 grading 1,315 g/t Ag, 14.36% Pb, 0.84% Zn, 0.24 g/t
Au, and 0.23% Cu from 161.50 m depth,
at an elevation of 300 m;
- Hole ZK62S3101 intersected a 0.97
m interval (0.89 m true width)
of vein S31 grading 1,764 g/t Ag, 36.49% Pb, 5.72% Zn, 0.13 g/t Au,
and 0.27% Cu from 80.19 m depth, at
an elevation of 239 m;
- Hole ZK04AS6E1002 intersected a 0.84 m interval (0.76
m true width) of vein S2 grading 2,497 g/t Ag, 29.05% Pb,
5.78% Zn, 0.12 g/t Au, and 0.23% Cu from 3.31 m depth, at an elevation of 353 m;
- Hole ZK50S2914 intersected a 1.22
m interval (0.88 m true width)
of vein S29 grading 2,097 g/t Ag, 1.44% Pb, 20.61% Zn, 0.32 g/t Au,
and 0.12% Cu from 218.16 m depth, at
an elevation of 341 m; and
- Hole ZK04AS6E1005 intersected a 3.50 m interval (3.35
m true width) of vein S2 grading 291 g/t Ag, 7.41% Pb, 0.94%
Zn, 0.12 g/t Au, and 0.04% Cu from 3.04
m depth, at an elevation of 354
m.
Drilling for Previous Low Priority Gold-Silver Veins within
the Resource Area and Step-Out Drilling Intersecting Gold-Silver
Veins 400 m to the East of the
Resource Area
The drilling continued intersecting and extending the east
dipping gold-silver S16 series, including S16W, S16W1, S16E, and
S16E3. A total of 44 holes, including 38 holes from this period and
six holes pending from the previous drilling program, targeted the
S16 vein series. Together with the tunneling programs, the
drill programs defined a mineralized block with a N-S strike length
of 500 m, and a 150 m down-dip extension. Drilling was focused
within the central portion of the block (300
m by 100 m), with drill hole
spacing ranging between 15 m by
15 m and 25
m by 25 m. Assay results for
33 holes from the previous drilling program were returned, with 23
holes intersecting gold mineralization.
The Company's No. 1 mill has been upgraded by installing a
Knelson Gravity Concentrator to maximize gold-silver ore recovery
from the SGX, HPG, LMW, and DCG mines.
Step-out drilling confirmed the continuity of the gold-silver
bearing S11 and S11E veins, approximately 400 m east of the resource area. The S11 series
gold-silver veins are sub-vertical and strike along a
northeast-southwest trend.
Highlights of the gold silver intercepts at the SGX mine:
- Hole ZK68AS16W002 intersected a 5.38 m interval (5.36
m true width) of vein S16W grading 52 g/t Ag, 1.08% Pb,
0.39% Zn, 3.93 g/t Au, and 0.01% Cu from 37.67 m depth, at an elevation of 340 m;
- Hole ZK74S16W08 intersected a 1.74 m interval (1.58
m true width) of vein S16E3 grading 3 g/t Ag, 0.01% Pb,
0.01% Zn, 5.57 g/t Au, and 0.01% Cu from 92.90 m depth, at an elevation of 246 m; and
- Hole ZK66AS16W002 intersected a 1.33 m interval (1.30
m true width) of vein S16W grading 56 g/t Ag, 0.34% Pb,
0.72% Zn, 4.61 g/t Au, and 0.04% Cu from 67.13 m depth, at an elevation of 341 m.

Tunneling Programs at the SGX
Mine
A total of 6,207 m of exploration
tunnels were developed at the SGX mine during this period. The
exploration tunneling, comprised of drifting, cross-cutting and
raising, was driven along and across major mineralized vein
structures to upgrade the drill-defined mineral resources, and to
test for new parallel and splay structures (Tables 2 and 3).

Mineralization is defined by silver equivalent value (AgEq) greater
than or equal to 135 g/t at the SGX mine
|
(Formula used for
AgEq calculation: AgEq = Ag g/t + 64.72 * Au g/t + 34.26 * Pb% +
19.08 * Zn%).

Quality Control
Drill cores are NQ size. Drill core samples, limited by apparent
mineralization contacts or shear/alteration contacts, were split
into halves by saw cutting. The half cores are stored in the
Company's core shacks for future reference and checks, and the
other half core samples are shipped in securely sealed bags to the
Chengde Huakan 514 Geology and Minerals Test and Research Institute
in Chengde, Hebei Province,
China, 226 km northeast of
Beijing, the Zhengzhou Nonferrous
Exploration Institute Lab in Zhengzhou, Henan
Province, China, and SGS in
Tianjin, China. All three labs are
ISO9000 certified analytical labs. For analysis, the sample is
dried and crushed to minus 1 mm and then split into a 200-300 g
subsample which is further pulverized to minus 200 mesh. Two
subsamples are prepared from the pulverized sample. One is digested
with aqua regia for gold analysis with atomic absorption
spectroscopy ("AAS"), and the other is digested with two-acids for
analysis of silver, lead, zinc, and copper with AAS.
Channel samples are collected along sample lines perpendicular
to the mineralized vein structure in exploration tunnels. Spacing
between sampling lines is typically 5
m along strike. Both the mineralized vein and the altered
wall rocks are cut by continuous chisel chipping. Sample length
ranges from 0.2 m to more than
1 m, depending on the width of the
mineralized vein and the mineralization type. Channel samples are
prepared and assayed with AAS at Silvercorp's mine laboratory
("Ying Lab") located at the mill complex in Luoning County,
Henan Province, China. The Ying lab is officially accredited
by the Quality and Technology Monitoring Bureau of Henan Province and is qualified to provide
analytical services. The channel samples are dried, crushed and
pulverized. A 200 g sample of minus 160 mesh is prepared for assay.
A duplicate sample of minus 1 mm is made and kept in the laboratory
archives. Gold is analysed by fire assay with AAS finish, while
silver, lead, zinc, and copper are assayed by two-acid digestion
with AAS finish.
A routine quality assurance/quality control ("QA/QC") procedure
is adopted to monitor the analytical quality at each lab. Certified
reference materials (CRMs), pulp duplicates and blanks are inserted
into each batch of lab samples. QA/QC data at the lab are attached
to the assay certificates for each batch of samples.
The Company maintains its own comprehensive QA/QC program to
ensure best practices in sample preparation and analysis of the
exploration samples. Project geologists regularly insert CRMs,
field duplicates and blanks to each batch of 30 core samples to
monitor the sample preparation and analysis procedures at the labs.
The analytical quality of the labs is further evaluated with
external checks by sending approximately 3-5% of the pulp samples
to higher level labs to check for lab bias. Data from both
the Company's and the labs' QA/QC programs are reviewed on a timely
basis by project geologists.
Guoliang Ma, P. Geo., Manager of
Exploration and Resource of the Company, is the Qualified Person
for Silvercorp under NI 43-101 and has reviewed and given consent
to the technical information contained in this news release.

CAUTIONARY NOTE
TO US INVESTORS
|
|
The disclosure in
this news release and referred to herein was prepared in accordance
with NI 43-101 which differs significantly from the requirements of
the U.S. Securities and Exchange Commission (the "SEC"). The
terms "proven mineral reserve", "probable mineral reserve" and
"mineral reserves" used in this news release are in reference to
the mining terms defined in the Canadian Institute of Mining,
Metallurgy and Petroleum Standards (the "CIM Definition
Standards"), which definitions have been adopted by NI
43-101. Accordingly, information contained in this news
release providing descriptions of our mineral deposits in
accordance with NI 43-101 may not be comparable to similar
information made public by other U.S. companies subject to the
United States federal securities laws and the rules and regulations
thereunder.

Investors are
cautioned not to assume that any part or all of mineral resources
will ever be converted into reserves. Pursuant to CIM Definition
Standards, "Inferred mineral resources" are that part of a mineral
resource for which quantity and grade or quality are estimated on
the basis of limited geological evidence and sampling. Such
geological evidence is sufficient to imply but not verify
geological and grade or quality continuity. An inferred
mineral resource has a lower level of confidence than that applying
to an indicated mineral resource and must not be converted to a
mineral reserve. However, it is reasonably expected that the
majority of inferred mineral resources could be upgraded to
indicated mineral resources with continued exploration. Under
Canadian rules, estimates of inferred mineral resources may not
form the basis of feasibility or pre-feasibility studies, except in
rare cases. Investors are cautioned not to assume that all or
any part of an inferred mineral resource is economically or legally
mineable. Disclosure of "contained ounces" in a resource is
permitted disclosure under Canadian regulations; however, the SEC
normally only permits issuers to report mineralization that does
not constitute "reserves" by SEC standards as in place tonnage and
grade without reference to unit measures.
|
|
Canadian standards,
including the CIM Definition Standards and NI 43-101, differ
significantly from standards in the SEC Industry Guide 7.
Effective February 25, 2019, the SEC adopted new mining disclosure
rules under subpart 1300 of Regulation S-K of the United States
Securities Act of 1933, as amended (the "SEC Modernization
Rules"), with compliance required for the first fiscal year
beginning on or after January 1, 2021. The SEC
Modernization Rules replace the historical property disclosure
requirements included in SEC Industry Guide 7. As a result of
the adoption of the SEC Modernization Rules, the SEC now recognizes
estimates of "Measured Mineral Resources", "Indicated Mineral
Resources" and "Inferred Mineral Resources". In addition, the
SEC has amended its definitions of "Proven Mineral Reserves" and
"Probable Mineral Reserves" to be substantially similar to
corresponding definitions under the CIM Definition Standards.
During the period leading up to the compliance date of the SEC
Modernization Rules, information regarding mineral resources or
reserves contained or referenced in this news release may not be
comparable to similar information made public by companies that
report according to U.S. standards. While the SEC
Modernization Rules are purported to be "substantially similar" to
the CIM Definition Standards, readers are cautioned that there are
differences between the SEC Modernization Rules and the CIM
Definitions Standards. Accordingly, there is no assurance any
mineral reserves or mineral resources that the Company may report
as "proven mineral reserves", "probable mineral reserves",
"measured mineral resources", "indicated mineral resources" and
"inferred mineral resources" under NI 43-101 would be the same had
the Company prepared the reserve or resource estimates under the
standards adopted under the SEC Modernization Rules.
