Silvercorp Reports Discovery Of Significant Mineralized Vein Structures In Its 2016 Exploration Program At The LMW Mine, Ying Mining District, China

VANCOUVER, British Columbia – January 30, 2017 – Silvercorp Metals Inc. ("Silvercorp” or the “Company”) (TSX:SVM) is pleased to report the results of its 2016 exploration program at the LMW mine, Ying Mining District, Henan Province, China.

The Company completed 17,410 meters (“m”) underground diamond drilling and 7,909m exploration tunneling in 2016 at the LMW mine. Highlights of the 2016 exploration results is the delineation of high-grade northwest-trending vein structures LM19W1 and S19W2 and other parallel vein groups. The 4,877m drift tunneling exposed a total of 1,931m of high-grade mineralized zones.

Highlights of selected mineralization zones exposed in exploration drift tunnels includes:

  • Drift Tunnel PD969-LM13-969-1NSYM exposed mineralization of 90m long and 0.56m wide (true width) grading 1,265 grams per tonne (“g/t”) silver (“Ag”), 8.86% lead (“Pb”) and 0.44% zinc (“Zn”) within vein structure LM13 on the 969m level;
  • Drift Tunnel SJ969-LM19W2-650-110NYM exposed mineralization of 105m long and 0.74m wide (true width) grading 761g/t Ag, 5.19% Pb and 1.08% Zn within vein structure LM19W2 on the 650m level; and
  • Drift Tunnel XPDN-LM19W1-650-112NYM exposed mineralization of 175m long and 0.84m wide (true width) grading 527g/t Ag, 3.95% Pb and 0.62% Zn within vein structure LM19W1 on the 650m level.

Highlights of selected intersections of drill holes includes:

  • Hole ZKX0351 intersected an 1.86m interval from 126.59m to 128.45m, 1.20m true width, of vein LM41 grading 222g/t Ag and 0.32% Pb at the 889m elevation, and a 0.51m interval from 131.50m to 132.01m, 0.49m true width, of vein LM17W grading 866g/t Ag, 7.97% Pb and 0.67% Zn at the 887m elevation;
  • Hole ZK13261 intersected a 0.62m interval from 358.57m to 359.19m, 0.37m true width, of vein LM19W1 grading 1,328g/t Ag, 4.94% Pb and 4.80% Zn at the 703m elevation, and an 1.46m interval from 395.50m to 396.96m, 0.89m true width, of vein LM19 grading 622g/t Ag, 1.98% Pb and 0.47% Zn at the 681m elevation; and
  • Hole ZKX0161B intersected a 2.45m interval from 146.64m to 149.09m, 1.86m true width, of LM13 grading 767g/t Ag, 0.87% Pb and 0.43% Zn at the 881m elevation.

Re-interpretation of previous exploration data in early 2015 resulted in identification of the northwest striking vein structures LM19W1 and LM19W2 at LMW mine. Underground drilling and exploration tunneling afterwards in 2015 and 2016 have controlled strike lengths of more than 700 m for both vein structures, and exposed stable and continuous high-grade mineralization zones in drift tunnels within the two newly defined structures. In addition to the known dominant northeast striking vein structures, discovery of vein structures LM19W1 and LM19W2 at LMW may indicate enormous exploration potential of the previously less-explored northwest striking vein structures in the Ying mining district, especially the TLP, LME and LMW mines.

Underground drill holes in 2016 were mainly designed to delineate the downdip and along-strike extensions of known mineralized vein structures in the production area and test for new veins in the adjacent less-explored areas.

The 2016 drilling program at LMW is briefly summarized in the following table:

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 parallel and splay structures.

The 2016 tunneling program at LMW is briefly summarized in the following table:

Tables 1 and 2 below list the assay results of some selected mineralized zones exposed in drift tunnels and mineralized intersections in drill holes in the 2016 exploration program.

Table 2: Selected results from the 2016 drilling program at the LMW mine

*Stepout: intersections adjacent to existing resource blocks for resource expansion;
**Test: intersections in open areas without known mineralized intersections nearby.

The exploration results ending June 30, 2016 will be incorporated in a NI43-101 mineral resource update report expected to be announced in the first quarter of 2017.

Exploration in 2017 at LMW will be mainly focused on vein groups LM14, LM16, LM17, LM19, LM30, LM32, and LM41. The Company has proposed a comprehensive program comprising 9,654m tunneling to upgrade the previously drill defined mineral resources between Level 900m and Level 550m, and 12,400m underground drilling to further trace the striking and downdip extensions of the target veins and test for new veins between the 520m and 0m elevations.

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, 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 thesample 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.

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.
