VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 01/04/11 -- Silvercorp Metals Inc. ("Silvercorp") (TSX: SVM)(NYSE: SVM) is pleased to report the results of its 2010 underground diamond drilling program at the southwest corner (also called LM Mine West) of the TLP Mining Permit area, Ying Mining District, Henan, China. This successful drill program has not only extended the existing veins to depth and along strike at the LM Mine West, but has also discovered 18 additional high grade silver (Ag) - lead (Pb) veins, increasing the total number of mineralized veins from 9 to 27. The drilling program has also revealed a new type of mineralization as some Ag-Pb veins (LM8 and LM8-1) contain high grade gold that may indicate the existence of gold-dominated mineralized veins in the area.

The diamond drilling program and the underground tunneling program aimed to upgrade inferred mineral resources to indicated and measured categories, and to explore and define new mineralized veins at the LM Mine West. A total of 16,984 meters (m) of drilling in 56 underground holes were completed by 3 underground drill rigs at the LM Mine West. Table 1 lists assay results for 40 holes which intercepted Ag-Pb mineralized veins, including three of the holes intercepting Ag-Pb veins with gold (Au) grades greater than 10 grams per tonne (g/t). Assay results for some drill intervals and the rest of the drill holes are still pending.

The mineralized veins are closely spaced, either being parallel or intersecting each other in "X" patterns. As a result, in many instances a drill hole or cross-cut tunnel can intercept multiple veins in a short distance. Additional tunneling and drill holes have been designed and work is underway to further define the striking and dipping extensions of these veins. A 380m deep shaft is currently being developed from the 980m elevation down to the 600m elevation to access these veins for mining. A re-suing mining method, which has been successfully used by the Company at the LM Mine West, will be applied to mine these narrow veins.

Selected significant intercepts are as follows:

--  Hole ZKX1703 intersected 7.51m of the LM17 vein grading 925 g/t Ag and
    1.12% Pb at the 747m elevation, including a 2.57m interval grading 1,461

LM16 was extensively explored by tunneling and drilling. Tunneling was done on the 916m and 880m levels through access PD8 and PD991, respectively. At the 916m level, a 90m drift developed along the vein intersected 68 g/t to 2,569 g/t Ag, 0.43% to 4.09% Pb, and 0.08% to 10.93% Zn over 0.10 to 0.95m true width.

LM17 Vein

The LM17 vein cut across veins LM14 and LM16 and strikes to the northeast and steeply dips to the northwest. LM17 was defined by 4 drill holes over an 80m striking length at elevations ranging from 750 to 864m. The drill hole intercepts include 151 to 925 g/t Ag and 0.32 to 3.6% Pb over 0.32 to 7.51m intervals.

LM19 Vein

The northwesterly orienting LM19 vein is parallel to and 200m southwest of LM8, which was cut through by LM7 without significant displacement. LM19 dips at 70 to 80 degree dipping angle to the northeast. The vein has been exposed over 151m in a drift along the vein on the 924m level through main access tunnel PD924. Three high grade pockets were intersected by tunneling, grading 70 to 453 g/t Ag and 1.22 to 2.77% Pb over 0.42 to 0.80m true width.

Quality Control

Drill cores are NQ size and drill core samples were taken from sawn half core limited by apparent massive galena sheet contact or shear/alteration contact.

The Company maintains a quality control program to ensure best practice in sampling and analysis of the drill core samples. The samples are shipped directly in securely sealed bags to the Analytical Lab of Henan Non-Ferrous Metals Geological and Exploitation Institute in Zhengzhou, located 215 km by road northeast of the TLP Mine.

The sample preparation consists of drying, crushing, and splitting of the sample to 250 grams, then the sample is pulverized to 200 mesh. Two acid digestion and AA finish are utilized on a 0.5 gram sample for lead and zinc. Titration is utilized as a modified process for higher grade materials. Silver is also analyzed using a two acid digestion on a 0.5 gram sample and AA finish. Both labs utilize a QA/QC system of duplicates, replicates and Standards.

Myles Gao, P.Geo, is the Qualified Person on the project under NI 43-101.
