VANCOUVER, Sept. 5, 2017 /CNW/ - Silvercorp Metals Inc.
("Silvercorp" or the "Company") (TSX:SVM / NYSE AMERICAN: SVM) is pleased to report results of the first half of its 2017
exploration programs at the HZG, HPG and LMW mines, Ying Mining District, Henan Province,
China.
In the first half of 2017, the Company completed a total of 21,675 meters ("m") of underground diamond drilling and 7,989m of
exploration tunneling at HZG, HPG and LMW mines. Exploration tunneling exposed significant high-grade mineralized zones beneath
the current production levels within major production veins, especially HZ20 at the HZG mine and H17 at the HPG mine. Underground
drilling continuously extended the major mineralized vein structures along strike and downdip at the three mines.
Highlights of selected mineralized zones exposed in exploration drift tunnels:
- Drift Tunnel PD820-HZ20-600-133-SYM exposed mineralization of 66m long and 1.21m wide (true width) grading 1,389 grams per
tonne ("g/t") silver ("Ag"), 0.40% lead ("Pb"), 0.67% zinc ("Zn") and 2.78% copper ("Cu") within vein structure HZ20 on the
600m level at HZG mine;
- Drift Tunnel PD3-H17-251-10NYM exposed mineralization of 61m long and 1.53m wide (true width) grading 66g/t Ag, 5.41% Pb,
2.59% Zn and 1.13g/t gold ("Au") within vein H17 on the 251m level at HPG mine; and
- Drift Tunnel XPDN-LM19W1-700-3NYM exposed mineralization of 80m long and 1.01m wide (true width) grading 514g/t Ag, 3.22%
Pb and 0.86% Zn within vein structure LM19W1 on the 700m level at LMW mine.
Highlights of selected intersections of drill holes:
- Hole ZK11905 at HZG mine intersected an 1.60m interval from 185.73m to 187.33m, 0.91m true width, of vein HZ20 grading
999g/t Ag, 1.84% Pb, 0.38% Zn and 1.12% Cu at the 761m elevation;
- Hole ZKX116F03 at LMW mine intersected a 0.95m interval from 60.92m to 61.87m, 0.82m true width, of vein LM33 grading
1,174g/t Ag, 8.34% Pb and 0.78% Zn at the 583m elevation; and
- Hole ZKX107N01 at LMW mine intersected a 3.13m interval from 464.55m to 467.68m, 2.17m true width, of vein LM14 grading
279g/t Ag, 1.55% Pb and 0.06% Zn at the 519m elevation.
Diamond drill holes are designed to define and upgrade inferred mineral resource blocks and test for new mineral resources.
Underground drilling is mainly conducted from 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 previous less-explored areas.
The first half of 2017 drilling programs at HZG, HPG and LMW mines are briefly summarized in the following table:

The 2017 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.

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, 226 km northeast
of Beijing, and the Zhenzhou Nonferrous Exploration Institute Lab in Zhengzhou, Henan Province, China, and both
labs are ISO9000 certified analytical lab. 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 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 service. 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 the 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 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.
Ruijin Jiang, P. Geo, reviewed the exploration data and prepared the scientific and technical
information regarding exploration results contained herein. Alex Zhang, P. Geo, VP exploration of
the Company, is the Qualified Person on the project as defined under National Instrument 43-101 and he has verified and approved
the contents of this news release.
