Silvercorp Reports Exploration Results at the HPG Mine, Ying Mining District, China

Silvercorp Reports Exploration Results at the HPG Mine, Ying Mining District, 
VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 06/11/13 --
Silvercorp Metals Inc. ("Silvercorp" or the "Company") (TSX:SVM)
(NYSE:SVM) is pleased to report the results from its 2012 underground
tunneling and diamond drilling exploration program at the HPG mine,
Ying Mining District, Henan Province, China. 
Highlights of selected mineralization zones exposed in underground

--  Drift PD2-530-H16-NYM1 at the 530 metre ("m") level along vein H16
    revealed a zone 50m in length, 1.06m true width grading 4.13 grams per
    tonne ("g/t") gold ("Au"), 94 g/t silver ("Ag"), 5.14% lead ("Pb") and
    3.12% zinc ("Zn"); 
--  Drift PD5-H16-570-SYM at the 570m level along vein H16 revealed a zone
    50m in length, 0.92m true width grading 5.96 g/t Au, 119 g/t Ag, 0.67%
    Pb and 0.96% Zn; and 
--  Drift PD2-530-H16-SYM at the 530m level alogn vein H16 revealed a zone
    65m in length, 0.60m true width grading 5.52 g/t Au, 27 g/t Ag, 1.35% Pb
    and 1.61% Zn. 

Highlights of selected intersections of drill holes: 

--  Hole ZK0014 intercepted an 1.16m interval, 0.71m true width of vein H4
    grading 1.15 g/t Au, 729 g/t Ag, 3.34% Pb and 7.30% Zn at the 345m
    elevation; and 
--  Hole ZK1705 intercepted an 1.53m interval, 1.18m true width of vein H16
    grading 4.19 g/t Au, 16 g/t Ag, 2.16% Pb and 0.89% Zn at the 382m

The purpose of the 6,900m underground tunneling program was to
further delineate and upgrade previously drill-defined resource
blocks within major vein structures H4, H5, H11, H13, H15, H16, H17,
and H18 between the 340m and the 766m elevations. Drift and crosscut
tunnels were developed at 30m to 50m intervals. A total of 1,118 chip
samples were collected. Mineralized zones with a total length of
1,542m were exposed in drift tunnels on different levels along the
major vein structures. 
The underground diamond drilling program was designed to test the
downdip and strike extension of the major mineralized vein structures
between the 200m and the 700m elevations. The drilling strategy was
adjusted in the second half of 2012 to focus on the upper portions of
the major vein structures close to the existing mining facilities. A
total of 14,980m in 63 holes was completed and 859 core samples were
collected. By the end of March 2013, the Company had received assay
results for the 63 holes drilled in 2012. 41 of the 63 holes
intercepted single or multiple gold-silver-lead-zinc mineralized
Tables 1 and 2 below list the assay results of some selected
mineralization zones exposed in tunnels and intersections in drill
In 2013, the Company is conducting a 3,795m underground tunnelling
and 20,000m diamond drilling program, including 1,600m of surface
drilling and 18,400m of underground drilling at the HPG mine. The
goal of the underground exploration program is to upgrade and expand
previously drill-defined resource blocks between the 300m and the
750m elevations within vein structures H12-1, H13, H16 and H17 and to
explore for new resources within unexplored sections of major vein
structures. The holes will be drilled from 11 underground drill
stations on levels 420m, 530m, 570m, 590m, and 630m using three
underground drill rigs and from two surface drill stations using one
surface rig.

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 Testing and Research Institute in
Chengde, China, 226 km northeast of Beijing, an ISO9000 certified
analytical lab. Adopted analytical method that 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.  
Chip 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 with 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.  
A routine quality assurance/quality control procedure is adopted at
each lab to monitor the analytical quality at the lab. Certified
reference materials (CRM), 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 a comprehensive quality assurance and quality
control program to ensure best practice in sample preparation and
analysis of the drill core samples. Project geologists regularly
insert certified reference materials (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% 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 timely
reviewed and evaluated by project geologists.
