SILVERCORP REPORTS HIGH GRADE MINERALIZATION FROM ITS Q1-Q3 2018 DRILLING PROGRAM

AT THE GC MINE IN GUANGDONG PROVINCE, CHINA

VANCOUVER, British Columbia – December 12, 2018 – Silvercorp Metals Inc. ("Silvercorp” or the

“Company”) (TSX:SVM / NYSE AMERICAN: SVM ) is pleased to repo rt results of its drilling program from

January 1 to September 31, 2018 at the GC silver-lead-zinc Mine, Guangdong Province, China.

During the first nine months of 2018, the Company continued the extensive drilling program at the GC

Mine, completing 132 underground diamond drill holes totaling 18,029 metres (m) with 3 underground

rigs. Results of the underground drilling consistently extended not only the major mineralized vein

structures along strike and downdip , but also the high-grade mineralization zones within major

production vein structures.

Highlighted drill hole intersections include:

 Hole 18CK3804 intersected a 1.70m interval from 36.67m to 38.37m, for a 1.52m true width in vein

V2E3, with grades of 736 g/t Ag, 0.84% Pb and 0.79% Zn at the -154m elevation;

 Hole 18CK28A07 intersected an 8.85m interval from 121.62m to 130.47m, for a 6.98m true width in

vein V2-4, grading 348 g/t Ag, 2.32% Pb and 4.81% Zn at the -302m elevation, and a 1.29m interval

from 177.95m to 179.24m, for a 0.92m true width in vein V2E, grading 65 g/t Ag, 5.46% Pb and 6.58%

Zn at the -343m elevation;

 Hole 18CK4206 intersected a 4.11m interval from 33.60m to 37.71m, for a 3.74m true width in vein

NV10, with grades of 118 g/t Ag, 0.91% Pb and 6.04% Zn at the -54m elevation; and

 Hole 18CK40A05 intersected a 0.80m interval from 26.16m to 26.96m, for a 0.77m true width in

vein V19-1, grading 86 g/t Ag, 15.01% Pb and 7.22% Zn at the -57m elevation.

The underground drilling program was mainly conducted from the current production levels to delineate

the downdip and along-strike extensions of known mineralized vein structures in the production area. It

also tested for new veins in previously less-explored areas . The drilling intersected high-grade

mineralization at elevation level as low as -735m, and the mineralization is still open at depth (Table. 1).

Quality Control

Drill core samples were taken from sawn half core for every 1.5m or limited by apparent wall rock and

mineralization contact. Half of the core was sent to the laboratory for analysis and the other half

retained for archiving. The samples are individually secured in cotton sample bags and then collectively

secured in rice bags for shipment to the on-site laboratory.

For analysis, the sample is dried and crushed to minus 1 mm and then split to a 200 -300 g subsample

which is further pulverized to minus 200 m esh. A duplicate sample of minus 1 mm is made and kept at

the laboratory archives. Two subsamples are prepared from the pulverized sample. One is digested with

two-acids for analysis of silver, lead, zinc and copper with AAS. The other is retained as pulp reject at the

lab for future reference.

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. Projec t 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 lab’s QA/QC programs are reviewed on a timely basis by project

geologists.

Guoliang Ma, P. Geo, Silvercorp’s Manager of Exploration and Resource, reviewed the exploration data

and prepared the scientific and technical information regarding exploration results contained herein. He

is the Qualified Person on the project as defined under National Instrument 43 -101 and has verified and

approved the contents of this news release.
