Silvercorp Reports Intercept of 10.87 Meters Grading 715 Grams per Tonne Silver, 6.85% Lead and 1.52% Zinc at the SGX mine, Ying Mining District, Henan Province, China

AUGUST 1, 2012

VANCOUVER, British Columbia – August 1, 2012 – Silvercorp Metals Inc. (“Silvercorp” or the “Company”) (TSX:SVM) (NYSE:SVM) is pleased to report the results of its on-going underground diamond drilling program for the first six months of 2012 at the SGX (Ying) mine (“SGX”), Ying Mining District, Henan Province, China.

The underground drilling in the first half of 2012 at SGX has been focused on expanding the known resource of major production veins S2, S7, S7-1 and S8. Limited drilling was also conducted on veins S14, S14-1, S16W and their branch veins. The drill program has significantly extended the mineralized zones to depth and along strike and it is expected that these results will expand the mineral resource reported in the recently completed NI 43 101 Technical Report for the Ying Mining District.

As of June 30, 2012, the Company had completed 22,121 meters (“m”) in 62 holes using six underground drill rigs.  Assay results for 66 holes, 18 of which were drilled in December 2011, were received while assays for 14 holes drilled in the first half of 2012 are pending. Of the 66 holes the Company received assay results for, 31 of the holes had high-grade silver-lead-zinc zones while the remaining holes intersected vein structures.

Drilling on the major production vein S2 was conducted primarily as infill drilling to upgrade the previously delineated resource blocks and has further defined the mineralized zones between the 100m and the 0m elevations of the vein.

Drilling on the other major production veins S7, S7-1 and S8 was intended to test the downdip extension under the current production sections to expand the known resource of these veins. Six of the eight holes drilled on S7 intersected significant mineralization and have extended the mineralization zone to the -50m elevation between exploration lines 22 and 32 in the north section of the vein. Six of the eight holes drilled on S8 defined the downdip extension of the mineralization which is now extended to the -50m elevation in the north portion of the vein. Five of the nine holes drilled on the vein S7-1 intersected high-grade mineralization and successfully extended the previously delineated high grade and wide mineralization zone from the 300m elevation to the 100m elevation between exploration lines 0 and 5 over 300 m along strike. All the newly defined high grade mineralization zones of the veins S2, S7, S7-1 and S8 will be easily accessible via the ramp currently under construction at the SGX mine and the existing shafts.

Limited drilling on veins S6, S14, S14-1, and S16W also showed that the mineralization of those veins further extends to depth.

Highlights of selected intercepts are as follows:

  • Hole ZK0026 intercepted 2.20m of Vein S2 grading at 411 grams per tonne (“g/t”) silver (“Ag”), 1.28% lead (“Pb”) and 6.02% zinc (“Zn”) at the 76.81m elevation, including a 1.36m interval grading 639 g/t Ag, 1.91% Pb and 7.69% Zn;
  • Hole ZK1438 intercepted 1.28m of Vein S6 grading 423 g/t Ag, 1.11% Pb and 9.07% Zn at the 78.47m elevation, including a 0.5m interval grading 1,014 g/t Ag, 2.47% Pb and 20.81% Zn;
  • Hole ZK8303 intercepted 5.61m of Vein S28 grading 121 g/t Ag, 2.03% Pb and 2.36% Zn at the 418.96m elevation, including a 0.67m interval grading 927 g/t Ag, 12.45% Pb and 13.90% Zn;
  • Hole ZK1036 intercepted 3.70m of Vein S6 grading 234 g/t Ag, 2.37% Pb and 1.25% Zn at the 137.33m elevation, including a 0.56m interval grading 1,387 g/t Ag, 13.91% Pb and 6.23% Zn;
  • Hole ZKY22A04 intercepted 2.29m of Vein S7 grading 1,043 g/t Ag, 3.35% Pb and 0.10% Zn at the 46.81m elevation, including a 1.25m interval grading 1,551 g/t Ag, 5.27% Pb and 0.11% Zn;
  • Hole ZK0508 intercepted 10.87m of Vein S7-1 grading 715 g/t Ag, 6.85% Pb and 1.52% Zn at the 209.58m elevation, including a 2.84m interval grading 1,347 g/t Ag, 13.52% Pb and 2.16% Zn and a 1.84m interval grading 1,121 g/t Ag, 13.59% Pb and 2.16% Zn;
  • Hole ZK0108 intercepted 4.21m of Vein S7-1 grading 250 g/t Ag, 6.76% Pb and 1.77% Zn.

Quality Control

Drill cores are in 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 four labs: the Analytical Lab of Henan Non-Ferrous Metals Geological and Exploitation Institute in Zhengzhou (Zhengzhou Nonferrous Lab), the Henan Rock Minerals Testing Center in Zhengzhou (Henan Testing Center), and the SGS lab in Tianjin. All labs are officially accredited labs in China. Adopted analytical methods in the three labs are as follows:

Zhengzhou Nonferrous Lab

The sample preparation consists of drying, crushing and splitting of a 250-gram subsample which is then pulverized to minus-200 mesh. Two-acid digestion and AAS finish are utilized on a 0.5-gram sample for silver, lead and zinc analysis. Titration is utilized as a modified process for higher grade materials.

Henan Testing Center

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.


Sample is dried, crushed and split to a 250-gram subsample which is further pulverized to 85 per cent passing 200 mesh. Fire assay and AAS finish are utilized for gold assay. Four-acid digestion and ICP-AES finish are used in analyzing silver, lead, zinc and copper.

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.
