Silvercorp Intercepts 33.29 Metres True Width Grading 151 g/t Silver, 0.68 Percent Lead, 1.51 Percent Zinc, and 0.30 Percent Tin at Its GC Project

Wednesday, February 20, 2013

Silvercorp Intercepts 33.29 Metres True Width Grading 151 g/t Silver, 0.68 Percent Lead, 1.51 Percent Zinc, and 0.30 Percent Tin at Its GC Project17:30 EST Wednesday, February 20, 2013VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 20, 2013) - Silvercorp Metals Inc. ("Silvercorp" or the "Company") (TSX:SVM)(NYSE:SVM) is pleased to report results from the ongoing infill and step-out drilling exploration program at the GC silver-lead-zinc project located in Guangdong Province, China including the discovery of several new mineralized veins.Highlights of selected intercepts and discoveries:Hole CK2102 intercepted 49.65 metres ("m"), 33.29m true width at the -9m elevation of vein V2 grading 151 grams per tonne ("g/t") silver ("Ag"), 0.68% lead ("Pb"), 1.51% zinc ("Zn") and 0.30% tin ("Sn"), including an interval of 4.81m, 3.42m true width at the -23m elevation grading 525 g/t Ag, 2.06% Pb, 1.99% Zn and 0.87% Sn;Hole CK1831 intercepted 3.85m, 3.50m true width at the 39m elevation of vein V2 grading 460 g/t Ag, 1.20% Pb, 2.95% Zn and 0.86% Sn, including an interval of 1.30m, 1.18m true width at the 39m elevation grading 923 g/t Ag, 0.21% Pb, 1.35% Zn and 1.84% Sn;Hole CK2410 intercepted 3.88m, 3.76m true width at the 107m elevation of vein V15-1 grading 609 g/t Ag, 0.41% Pb, 0.56% Zn and 0.03% Sn, including an interval of 1.16m, 1.13m true width at the 107m elevation grading 698 g/t Ag, 0.63% Pb, 0.79% Zn and 0.03% Sn;Hole CK10450 intercepted 7.84m, 5.76m true width of vein V28 at the 97m elevation grading 359 g/t Ag, 1.55% Pb, 1.09% Zn and 0.03% Sn; andHole CK2001 intercepted 3.15m, 2.76m true width at the 47m elevation of vein V9W-2 grading 441 g/t Ag, 3.29% Pb, 5.71% Zn and 0.16% Sn, including an interval of 1.40m, 1.23m true width at the 46m elevation grading 661 g/t Ag, 4.80% Pb, 5.98% Zn and 0.27%Sn. Discovery of new veins V25, V26, V28 as well several other new veins (referred to as "New" in tables 1 and 2 below) which have not yet been named.The purpose of the 2012 GC project surface and underground drilling program was to upgrade the classification of the known resource blocks and further define and extend known vein structures in preparation for mining in 2013.Using two underground drill rigs to achieve a drill spacing of approximately 25m by 25m, drilling of V2 was focused on an area 300m in length from mine section lines 10 through 30 and 150m in vertical depth from the 100m elevation down to the -75m elevation. Access to V2 at the 20m elevation was gained via the main ramp and existing cross-cuts. In March 2013 Silvercorp expects to have an additional access point to V2 when the exploration ramp reaches the -50 m elevation. Present drill results (as evidenced by drill hole CK2102) indicate that V2 is a thick, continuous zone that would be amenable to bulk tonnage mining. In addition to its thickness, V2 also contains high-grade silver and tin mineralization. For example drill hole CK1831 intercepted 3.50m true width grading 460 g/t Ag, 1.20% Pb, 2.95% Zn and 0.86% Sn at the 39m elevation. As noted in the Company's news release of November 19, 2012, the presence of tin is expected to enhance the economics of the GC project.Drilling of the V9 vein group (V9, V9-1, V9W1 and V9W-2 veins) was conducted in an area 400m in length from mine section lines 14 through 32 and 150m in vertical depth between the 0m elevation and the 150m elevation using three underground drill rigs. Access to the V9 vein group was achieved via the exploration ramp with existing drifts and cross-cuts at elevations of 150m, 100m, 50m and 0m.In addition to the V2 and the V9 vein groups, drilling has also further defined vein groups V5, V6, V8, V13, V14 and V15. Veins V25, V26, and V28 are new discoveries. Assay results have been received for 97 drill holes totaling 7,037m of drilling. Additional assays results for twelve holes are pending. In 2013, Silvercorp plans to continue with its infill and step-out drilling program at the GC project and currently has five underground drill rigs and two surface drill rigs on site.The following tables are highlights of selected intercepts from the V2 and the V9 vein groups including intersections from potential veins and new discoveries at the GC project.

ControlDrill 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.Brian O'Connor P.Geo., is the Qualified Person on the project as defined under National Instrument 43-101.
