VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jun 11, 2013) - Silvercorp Metals Inc. ("Silvercorp" or the "Company") (SVM.TO) (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 tunnels:
- 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 elevation.
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 zones.
Tables 1 and 2 below list the assay results of some selected mineralization zones exposed in tunnels and intersections in drill holes.
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.

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.
