Silvercorp Reports Intercept of 415 g/t Ag, 1.6% Pb and 1.93%


Silvercorp Reports Intercept of 415 g/t Ag, 1.6% Pb and 1.93% Zn Over 7.66 Metres True Width at the GC Project, Guangdong Province, China

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 11/19/12 -- Silvercorp Metals Inc. ("Silvercorp" or the "Company") (TSX:SVM)(NYSE:SVM) is pleased to report results from the 2012 infill and step-out drilling program for vein V2 ("V2") and the V9 vein group at the GC silver-lead-zinc project located in Guangdong Province, China.

V2 is the largest mineralized vein structure in the current resource and was previously delineated by surface diamond drilling with spacing of 100 metres ("m") by 100m. The vein is approximately 1,000m in length along strike and 550m in dip direction between the 180m elevation and the -450m elevation. The V9 vein group consists of vein structures V9, V9W-1, V9W-2 and V9-1, of which V9W-2 is the most important mineralized structure and was discovered following underground tunneling and drilling in the first half of 2012. In the second half of 2012 the aim of the underground drilling program is to upgrade the easily-accessible resource blocks of V2 and to further define and extend the high-grade V9W-2 vein for initial mining.

Silvercorp commenced underground infill drilling of V2 and infill and step-out drilling of the V9 vein group in July 2012. Drilling of V2 has been focused on an area 300m in length and 150m in vertical depth (from the 100m elevation down to the -50 m elevation) using two underground drill rigs with spacing of approximately 25m by 25m.

Drilling of the V9 vein group was conducted in an area 400m in length and 150m in vertical depth between the 0m elevation and the 150m elevation using three underground drill rigs.

Highlights of selected intercepts are as follows:


 
--  Drill Hole CK1425 intercepted over 9.58m interval, 7.60m true width, of
    V2 grading 176 grams per tonne ("g/t") silver ("Ag"), 0.60% lead ("Pb"),

    elevation, including an interval of 1.73m, 1.28m true width, grading 606

--  Drill Hole CK1800 intercepted over 12.15m interval, 8.89m true width, of
    V2 grading 155 g/t Ag, 0.96% Pb, 2.89% Zn and 0.31% Sn at the 13m
    elevation, including an interval of 2.11m, 1.55m true width, grading 527
    g/t Ag, 0.42% Pb, 0.59% Zn and 1.12% Sn; 
 
--  Drill Hole CK2100 intercepted over 11.09m interval, 8.46m true width, of
    V2 grading 185 g/t Ag, 5.63% Pb, 3.91% Zn and 0.36% Sn at the 5m
    elevation, including an interval of 2.46m, 2.25m true width, grading 443
    g/t Ag, 18.54% Pb, 9.52% Zn and 0.62% Sn; 
 
--  Drill Hole CK1651 intercepted over 4.74m interval, 3.31m true width, of
    V9 grading 233 g/t Ag, 1.17% Pb, 11.78% Zn and 0.21% Sn at the -16m
    elevation; 
 
--  Drill Hole CK1753 intercepted over 10.55m interval, 7.66m true width, of
    V9W-1 grading 415 g/t Ag, 1.60% Pb, 1.93% Zn and 0.04% Sn at the 69m
    elevation, including an interval of 1.81m, 1.31m true width, grading
    1,010 g/t Ag, 0.95% Pb, 1.52% Zn and 0.05% Sn and an interval of 1.36m,
    0.99m true width, grading 1,140 g/t Ag, 8.49% Pb, 5.78% Zn and 0.09% Sn;

    elevation; 
 
--  Drill Hole CK1925 intercepted over 3.75m interval, 3.38m true width, of
    V9-1 grading 288 g/t Ag, 0.57% Pb, 0.91% Zn and 0.07% Sn at the 36m
    elevation, including an interval of 1.44m, 1.30m true width, grading 500
    g/t Ag, 0.19% Pb, 1.24% Zn and 0.07% Sn. 

Of the 25 holes completed on V2, 17 holes intercepted high-grade silver-zinc-lead mineralization which confirmed the wide high-grade intercepts in the previously reported widely-spaced surface diamond drilling program. Two holes, CK1100 and CK1216 at the western end of V2 encountered fractured structures and no drill core was recovered. Six holes were drilled in the artisanal area which had been mined out; three holes (Drill Holes CK1300, CK1409 and CK1631) penetrated through the narrow mined out stopes intercepting the limited mineralization at the footwall of the old stopes. The other three holes were abandoned.

Table 1 below contains assay results for 17 holes that intercepted mineralization of V2. Based on the results of 14 holes (Drill Holes CK1300, CK1409 and CK1631 have been excluded since these holes drilled into mined out stopes and actual interceptions of the vein are unknown), V2 has an average true width of 5.98m. In addition to silver, lead, and zinc, V2 also contains significant tin. The drill intervals indicate that the hanging wall of V2 is dominated by silver-lead-zinc mineralization with a lead-zinc grade greater than 25% (e.g. Drill Hole CK2100) while the footwall of V2 is dominated by silver-tin mineralization with tin grades in excess of 1% such as Drill Hole CK1800.

Based on the price of tin concentrate (60% tin) in Hunan Province as at November 14, 2012 (being US$19,680 per tonne or US$328 per 1% of tin in concentrate), the presence of tin is expected to enhance the economics of the GC Project. The 1,600 tonne per day mill at the GC project has been designed to include a tin gravity circuit and as such the Company expects to be able to realize the value of tin contained in mineralization. Metallurgical testing indicates that the Company can expect a tin recovery rate of greater than 40%.

As of the end of October 2012, 25 drill holes totalling over 3,800m were completed on V2 and 23 drill holes totalling over 5,000m were completed on the V9 vein group. Assay data for 12 of the 23 holes on the V9 vein group was received and nine holes intercepted mineralization (Table 2). V9W-2 has been extended for more than 400m along strike using step-out drilling and the western section of the vein has been infilled with grid drilling spaced at 25m by 25m. The Company plans to commence the development of initial mining stopes within the V2 and V9W-2 mineralized structures in 2013.

Silvercorp is continuing with its infill and step-out drilling program at the GC Project and currently has on site five underground drill rigs and two surface drill rigs.

Quality Control

Drill cores are in NQ size. Drill core samples, from 1.00m to 1.50m in length, or limited by apparent mineralization contact or shear/alteration contact, were split into halves by saw cutting. One half of the cores are stored in the Company's core shacks for future reference and checking and the other remaining samples are shipped in security sealed bags to ALS Chemex in Guangzhou, China (Certification ISO 9001), located approximately 180km southeast of the GC project site for sample preparation and assay.

Sample preparation consists of drying, crushing and splitting of samples to 250 grams and then they are pulverized to 200 mesh. Silver, lead, and zinc in drill core samples were analyzed by aqua regia digestion and AAS finish. Tin was analyzed by fusing with peroxide then by leaching the melt and acidifying to precipitate the tin for AAS finish.

The Company maintains a comprehensive quality assurance and quality control program to ensure best practices 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 reviewed and evaluated in a timely manner by project geologists.
