Silvercorp Metals Inc. ("Silvercorp” or the “Company”) (TSX / NYSE
American: SVM) is pleased to report results of its exploration
programs from April 1, 2018 to June 30, 2019 at the LMW mine, Ying
Mining District, Henan Province, China. Exploration drilling
is ongoing at the LMW mine and all other mines at the Ying Mining
District.
During this period, Silvercorp continued its
extensive exploration programs and completed 21,272 metres (“m”) of
underground diamond drilling and 3,274m of exploration tunneling at
the LMW mine. Results of underground drilling continuously extended
the major mineralized vein structures along strike and downdip, and
exploration tunneling exposed high-grade mineralization zones
within major production vein structures.
Highlights of selected drill hole
intersections:
- Hole ZKX11111 intersected a 1.34m
interval from 135.86m to 137.20m, 0.97m true width, of vein LM17W1
grading 1,211 grams per tonne (“g/t”) silver (“Ag”), 11.58% lead
(“Pb”), and 0.92% zinc (“Zn”) at the 634m elevation;
- Hole ZKX1302 intersected a 1.22m
interval from 121.20m to 122.42m, 1.21m true width, of a new vein
grading 661g/t Ag, 14.00% Pb, and 0.28% Zn at the 708m elevation;
and
- Hole ZKX0513 intersected a 1.66m
interval from 185.43m to 187.09m, 1.36m true width, of vein LM17W
grading 859g/t Ag, 4.53% Pb, and 0.31% Zn at the 661m
elevation.
The underground drilling program is being
conducted with three underground rigs 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 from April 1, 2018 to June
30, 2019 at the LMW mine is briefly summarized in the following

*Mineralized intersection in drill holes is
defined by silver equivalent value (AgEq) greater than or equal to
130 g/t.
Highlights of selected mineralization zones
exposed in exploration drift tunnels:
- Drift Tunnel PD969-LM12E-969-9NYM
exposed mineralization 52m long and 0.54m wide (true width) grading
958g/t Ag, 2.77% Pb, and 0.22% Zn within vein structure LM12E on
the 969m level;
- Drift Tunnel
PD969Shaft-LM32-600-116SYM Extension exposed mineralization 83m
long and 0.32m wide (true width) grading 896g/t Ag, 3.31% Pb, and
0.71% Zn within vein structure LM32 on the 700m level;
and
- Drift Tunnel XPDS-LM16-725-117NYM
exposed mineralization 110.5m long and 0.85m wide (true width)
grading 517g/t Ag, 2.72% Pb, and 0.39% Zn within vein structure
LM16 on the 725m level.
The exploration tunneling, comprising 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.
Exploration tunneling in the 2018-2019 exploration program at LMW
has been mainly conducted between elevation levels 550m and
969m.
The tunneling program from April 1, 2018 to June
30, 2019 at the LMW mine is briefly summarized in the following

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 checking, and the other half core samples are
shipped in security-sealed bags to the Chengde Huakan 514 Geology
and Minerals Test and Research Institute in Chengde, Hebei
Province, China, 226km 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 with 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 in 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 about 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.
