Silvercorp Metals Inc. ("Silvercorp” or the “Company”) (TSX/NYSE
American: SVM) is pleased to report results of its exploration
programs at the SGX mine, Ying Mining District, Henan Province,
China. Exploration drilling is ongoing at the SGX mine, and
all other mines at the Ying Mining District.
From April 1, 2018 to September 30, 2019, the
Company completed 41,127 metres (“m”) of diamond drilling with 7
underground rigs and 30,748m of exploration tunneling between
elevation levels 110m and 710m. Results from underground
drilling extended the major mineralized vein structures along
strike and downdip, and exploration tunneling exposed high grade
mineralized zones within major production vein structures.
During this period, many mineralized parallel and splay
structures were discovered near the known mineralized
zones. Particularly, the new discovery of the parallel veins
S1W3 and S1W5 with significant drill results within the S1 zone has
expanded the mineralization to the northwest of the SGX mine.
In addition, results from the drilling and tunneling programs
have confirmed that the mineralized vein S32 at the SGX mine
is the same vein structure as vein HZ20 at the HZG mine to the
south of the SGX mine. The combined strike length of this vein
structure is approximately 2,800m, with tunneling and infill
drilling still ongoing at the connecting area of this vein
structure.
Highlights of selected drill hole
intersections:
- Hole ZK12AS1W201 intersected a 1.20m interval from 44.09m to
45.29m, 0.85m true width, of vein S2W2_1 grading 1,102 grams per
tonne (“g/t”) silver (“Ag”), 16.39% lead (“Pb”) and 1.55% zinc
(“Zn”) at the 128m elevation;
- Hole ZK14AS1W201 intersected a 1.11m interval from 23.49m to
24.60m, 0.63m true width, of vein S2W2_1 grading 1,134 g/t Ag,
29.24% Pb and 1.18% Zn at the 132m elevation;
- Hole ZK10S18E002 intersected a 1.07m interval from 4.96m to
6.02m, 1.04m true width, of vein S14E1 grading 1,000 g/t Ag, 0.46%
Pb and 0.51% Zn at the 452m elevation, and a 0.61m interval from
155.38m to 156.00m, 0.57m true width, of vein S35E grading 231 g/t
Ag, 1.04% Pb and 0.09% Zn at the 393m elevation; and
- Hole ZKDBS1W21201 intersected a 0.37m interval from 413.36m to
413.73m, 0.34m true width, of newly discovered vein S1W5 grading
2,543 g/t Ag, 19.82% Pb and 7.24% Zn at the 264m elevation.
The underground drilling program is mainly
conducted from the current production levels to delineate the
downdip and along-strike extensions of known mineralized vein
structures in the production area and test for new veins in the
previously less-explored areas.
The drilling program at SGX is summarized in the
following table:

[1] Ore intersection is defined by silver
equivalent value (AgEq) greater than or equal to 140 g/t.[2] The
formula for AgEq is: Ag g/t + 37.8695 x Pb % + 21.3611 x Zn %
Highlights of selected mineralized zones exposed
in exploration drift tunnels:
- Drift Tunnel CM105-S2SJ-S2W2-140-12ANYM exposed mineralization
145m long and 0.91m wide (true width) grading 699 g/t Ag, 21.66% Pb
and 3.31% Zn within vein structure S2W2 on the 140m level;
- Drift Tunnel CM105-S2SJ-S2W2-140-12ASYM exposed mineralization
170m long and 0.96m wide (true width) grading 698 g/t Ag, 13.60% Pb
and 2.55% Zn within vein structure S2W2 on the 140m level;
- Drift Tunnel CM101-S19-210-4SYM exposed mineralization 82m long
and 1.20m wide (true width) grading 436 g/t Ag, 14.09% Pb and 1.75%
Zn within vein structure S19 on the 210m level; and

and 0.92m wide (true width) grading 779 g/t Ag, 14.65% Pb and 4.28%
Zn within vein structure S29 on the 210m level.
The exploration tunneling at the SGX mine,
comprising of drifting, crosscutting and raising, was driven along
and across major mineralized vein structures to upgrade drill
defined mineral resources and test for new parallel and splay
structures, and is summarized in the following table:

Quality Control
Drill cores are NQ size. Drill core
samples, limited by apparent mineralization contact or
shear/alteration contact, 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, and the Zhengzhou
Nonferrous Exploration Institute Lab in Zhengzhou, Henan Province,
China. Both labs are ISO9000 certified analytical labs.
For analysis the sample is dried and crushed to minus 1mm and
then split to a 200-300g 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 5m along
strike. Both the mineralized vein and the altered wall rocks
are cut by continuous chisel chipping. Sample length ranges
from 0.2m to more than 1m, 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 200g sample of minus 160
mesh is prepared for assay. A duplicate sample of minus 1mm
is made and kept at the laboratory archives. Gold is analysed
by fire assay with AAS finish, and 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 lab batch of 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 CRM, 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.
Mr. 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.
