VANCOUVER, Nov. 16, 2015 /CNW/ - Silvercorp Metals Inc. ("Silvercorp" or the "Company") (TSX:SVM) is pleased to report the results of its on-going exploration program in the first three quarters of 2015 at the SGX mine, Ying Mining District, Henan Province, China.

The 2015 exploration program consists of (1) resource upgrade tunneling and step out drilling on major production vein structures S2, S4, S6, S7, S7-1, S8, S14, S16W, S21, S22 and S29 and (2) definition drilling of their parallel subzones and splay structures and veins that have not been well explored such as S19 and S19E. Results of the current exploration program continues to demonstrate the strike and downdip extension of major mineralized vein structures. The most significant new discovery thus far has been the S19 that is becoming an important production vein utilizing the existing mining facilities in the nearby S16W and S7-1 vein structures.

Highlights of selected intersections of drill holes for the S19 vein:

  • Hole ZK03S7-111 intersected a 3.94 meter ("m") interval from 66.47m to 70.41m, 2.19m true width, of vein S19 grading 422 grams per tonne ("g/t") silver ("Ag"), 18.32% lead ("Pb") and 0.32% zinc ("Zn") at the 212m elevation, including an 1.5m interval, 0.83m true width, grading 837g/t Ag, 49.64% Pb and 0.76% Zn, a 0.64m interval from 278.01m to 278.65m, 0.4m true width, of vein S7-1 grading 753g/t Ag, 6.87% Pb and 2.58% Zn at the 40m elevation, and an 1.63m interval from 285.56m to 287.19m, 1.08m true width, of vein S7-1E grading 308g/t Ag, 0.69% Pb and 4.06% Zn;
  • Hole ZK3A11 intersected an 1.73m interval from 37.12m to 38.85m, 1.19m true width, of vein S19 grading 596g/t Ag, 2.31% Pb and 0.42% Zn at the 253m elevation, and a 2.04m interval from 182.33m to 184.37m, 1.93m true width, of vein S7-1 grading 1,000g/t Ag, 2.03% Pb and 5.24% Zn at the 199m elevation;
  • Hole ZK9AS1901 intersected a 2.23m interval from 139.16m to 141.39m, 1.46m true width, of vein S19 grading 398g/t Ag, 2.96% Pb and 1.69% Zn at the 387m elevation, including a 0.87m interval, 0.57m true width, grading 996g/t Ag, 5.68% Pb and 2.50% Zn; and
  • Hole ZK07S1902 intersected an 1.49m interval from 152.06m to 153.55m, 0.91m true width, of vein S19E grading 293g/t Ag, 9.42% Pb and 0.43% Zn at the 344m elevation, and a 7.4m interval from 182.02m to 189.42m, 2.71m true width, of vein S19 grading 212g/t Ag, 5.62% Pb and 0.88% Zn at the 322m elevation, including a 0.9m interval, 0.37m true width, grading 1,178g/t Ag, 19.55% Pb and 4.42% Zn.

Highlights of mineralized zones exposed in drift tunnels for the S19 vein:

  • Drift Tunnel PD700-S19-490-15NYM exposed mineralization of 100m long and 0.97m wide grading 430g/t Ag, 5.55% Pb and 3.95% Zn within vein structure S19 on the 490m level.

A total of 25,623m diamond drilling in 97 holes were completed with 8 underground rigs in the first three quarters of 2015. Most of the holes were designed as stepout and test holes to penetrate multiple vein structures for resource expansion and new resource delineation between the 640m and minus 110m elevations. Drill stations were mainly located in underground workings at the present development and mining levels. Stepout holes were drilled around previously defined resource blocks to further expand the known mineral resources and test drilling was targeted at the strike and downdip extensions of known mineralized vein structures to seek new mineralized zones and parallel vein structures. A total of 1,376 core samples were collected from intersections of altered and mineralized vein structures. As of September 30, the Company received assay results for 92 holes, including 17 holes drilled in late 2014 and 75 holes completed in 2015. 54 of the 92 holes intersected one or multiple mineralized zones and other holes intercepted target structures.

Exploration tunneling comprised drifting, crosscutting and raising between levels 750m and 180m. A total of 10,232m underground tunneling, including 6,960m drift tunneling, was driven along and across major production veins on 14 levels, and 3,408 channel samples were collected. As of September 30, 2015, the on-going exploration tunneling program exposed a total of 2,854m mineralization of 0.74m in average width grading 298g/t Ag, 5.7% Pb and 3.03% Zn. The exposed mineralization constitutes 41% of the completed 6,960m drift tunneling.

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

Longitudinal sections for the veins showing the location of the drilling results in this news release are available at the following Company link:

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 the 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 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. A 0.5g pulp sample is treated with two-acid digestion and assayed for silver, lead, zinc and copper with AAS.

A routine quality assurance/quality control procedure is adopted at each lab 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 quality assurance and quality control program to ensure best practice 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.

Ruijin Jiang, P. Geo. reviewed the exploration data and prepared the scientific and technical information regarding exploration results contained herein. Alex Zhang, P. 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.
