VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan 31, 2013) - Silvercorp Metals Inc. ("Silvercorp" or the "Company") (SVM.TO)(SVM) is pleased to report the results from its underground diamond drilling program for the second half of 2012 at the LM Mine West ("LM West"), Ying Mining District, Henan Province, China. A total of 43,709 metres ("m") of drilling in 123 holes was completed from January 1, 2012 to December 31, 2012 at LM West.
Highlights of selected intercepts:
- Hole ZKX03S31 intercepted a 19.13m interval, 18.80m true width, of Vein LM7 grading 368 grams per tonne ("g/t") silver ("Ag") and 1.78% lead ("Pb") at the 863m elevation, including an interval of 8.10m, 7.95m true width, grading 788g/t Ag and 3.60% Pb;
- Hole ZKX3404 intercepted a 10.44m interval, 6.44m true width, of Vein LM17 grading 369g/t Ag and 1.70% Pb at the 599m elevation, including an interval of 2.45m, 1.51m true width, grading 1,323g/t Ag and 6.28% Pb;
- Hole ZKX0808 intercepted a 3.53m interval, 3.05m true width, of Vein LM12-2 branch grading 335g/t Ag, 2.23% Pb and 0.51% zinc ("Zn") at the 603m elevation, including an interval of 0.67m, 0.58m true width, grading 1,456g/t Ag, 10.11% Pb and 1.92% Zn; and
- Hole ZKX1532 intercepted a 3.17m interval, 2.14m true width, of Vein W5 grading 427g/t Ag, 2.32% Pb and 0.49% Zn the 831m elevation, including an interval of 1.02m, 0.69m true width, grading 1,324g/t Ag, 6.81% Pb and 1.47% Zn.
Underground drilling was conducted from near surface tunnels between the 900m and 950m elevations and was mainly focused on major mineralized vein structures LM7, LM8, LM10, LM11, LM12, LM13, LM14, LM16, LM17, W5 and W6 as well as their parallel structures to expand and upgrade the previously defined mineralization zones within these mineralized vein structures. Drill results from the first half of 2012 were released on August 20, 2012.
The drilling strategy in the second half of 2012 was revised; instead of focusing on step out drilling at depths below the 600m elevation the Company began testing the lateral extensions of the mineralization zones and in-fill drilling at shallow depth or the upper portions (i.e. above the 600m elevation) of the major vein structures. These results are from areas that are accessible from existing mining development.
A total of 24,214m of drilling in 76 holes was completed from July 1 to December 31, 2012. As of December 31, 2012, assay results for 59 holes were received, 10 of which are for holes completed in the first half of 2012 and assay results for 27 holes are pending. Of the 59 holes with assay results, 25 holes have intercepted significant silver-lead-zinc mineralization and the remainder intercepted mineralization and alteration structures. Table 1 below lists assay results for these 25 holes that intercepted significant mineralization at LM West.

A 29,000m underground drilling program is planned in 2013 for the LM Mine West which will continue the present focus on assessing major vein structures which are accessible from existing mining development, drilling the lateral extensions of the mineralization zones and in-fill drilling at shallow depth, or the upper portions (i.e. above the 600m elevation) of the vein structures.
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. Sample is dried and crushed to minus 1mm and then split to a 200g to300g 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 5m along strike. Both the mineralized vein and the altered wall rocks are cut with continuous chisel chipping. Sample lengths range from 0.2m to more than 1m, 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.
