Silvercorp Surface Diamond Drilling Intercepted 3.13 Meters of 432 Grams per Tonne Silver at the GC Silver-Lead-Zinc Project in Guangdong Province, Southern China08:00 EST Tuesday, January 17, 2012VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 17, 2012) - Silvercorp Metals Inc. ("Silvercorp") (TSX:SVM)(NYSE:SVM) is pleased to report the results for its 2011 surface drilling program at the GC silver-lead-zinc project located in Guangdong Province, Southern China. The drill program has discovered four new high grade silver (Ag), lead (Pb), and zinc (Zn) veins and a number of vein structures and isolated mineralized pockets, increasing the total number of mineralized veins at the GC property to 33 veins. The program also successfully extended the existing veins further to down dip and striking directions.Selected significant intercepts are as follows:Hole ZK40605 intercepted 0.40m interval of the V6 vein grading 2,450 g/t Ag, 1.29% Pb, 11.65% Zn, and 0.41% tin (Sn);Hole ZK2406 intersected 3.13 m interval of the V9W-2 vein grading 432 g/t Ag, including 0.40 m interval containing 3120 g/t Ag, 0.95% Pb, 3.67% Zn, and 0.38% Sn;Hole ZK40603 intercepted 1.15 m interval of the V6 vein grading 489 g/t Ag, 2.57% Pb, 3.81% Zn, and 0.70% Sn;Hole ZK40604 intercepted 0.55 m interval of the V6-0 vein grading 1,495 g/t Ag, 6.72% Pb, 7.76% Zn and 0.41% Sn;Hole ZK40203 intercepted 0.40 m interval of the V6 vein grading 637 g/t Ag, 0.91% Pb, 1.13% Zn, 0.05% Sn;Hole ZK3208 intercepted 1.86 m interval of the V14 vein grading 525 g/t Ag, 2.45% Pb, 1.55% Zn, and 0.07% Sn, including 0.56 m interval containing 1,595 g/t Ag, 7.90% Pb, 3.97% Zn, and 0.16% Sn;Hole ZK1204 intersected 3.42 m interval of the V6-0 vein grading 305 g/t Ag and 2.48% Pb, 2.03% Zn, and 0.34% Sn, including 1.26 m interval containing 566 g/t Ag, 0.55% Pb, 0.69% Zn, and 0.17% Sn; 0.55 m interval of the vein V8-2 grading 1,060 g/t Ag, 2.06% Pb, 0.52% Zn, and 0.04% Sn; andHole ZK2006 intercepted 0.64 m interval of the V9 vein grading 470 g/t Ag, 0.39% Pb, 3.42% Zn, and 0.16% Sn.The surface drilling program aimed to upgrade inferred mineral resources to the indicated and measured categories, and to explore and define new mineralized veins at the GC project. During 2011, a total of 14,370 meters (m) comprising of 34 holes were completed by two drill rigs at the property. Table 1 below lists assay results for 22 holes which intercepted Ag-Pb-Zn mineralization veins; the remaining 12 holes that intersected vein structures without significant assay results are not listed.Newly Discovered VeinsThe four newly discovered veins are V6-1, V8-2, V9W-1 and V9W-2.V6-1 VeinThe vein is parallel to V6 vein, extends northwesterly for over 250 m and dips to the southwest at 85 degree angle for more than 340 m from -5m to -279m elevation. The vein is at about 33 m southwest of and parallel to the vein V6. Six drill holes intercepted the vein with four holes hitting significant mineralization that contains grades averaging 18 to 117 g/t Ag, 0.03 to 12.8% Pb, 1.52 to 3.45% Zn, and 0.16 to 0.73% Sn over 0.16 to 0.72 m true width.V8-2 VeinV8-2 is parallel to and at 8 m southwest of the northwesterly striking V8 vein and extends more than over 300 m between line 24 and 32. The vein steeply dips to southwest and extends over 525 m in depth from 115m to -109m elevation. Four drill holes intersected the significantly mineralized sections of the vein, containing grades averaging 259 to 1,060 g/t Ag, 1.78 to 7.09% Pb, 0.52 to 5.94% Zn, and 0.11 to 0.47% Sn over 0.14 to 0.47 m true width.V9W-1 and V9W-2 VeinsThese veins are part of V9 vein system and are parallel to V9 vein. The veins extend northwesterly over 200 m and dip to southwest at about 71 degree dipping angle. V9W-1 and V9W-2 are at hanging wall of V9 Vein about 27 m and 30 m away for the V9 respectively. Both veins are defined between explorations 20 and 24. The V9W-1 vein was intercepted by two drill holes which intercepted the vein from 164m to 79m elevation and contains grades averaging 55 to 108 g/t Ag, 0.19 to 1.18% Pb, 2.03 to 3.13% Zn, and 0.03 to 0.22% Sn over 0.14 to 2.32 m true width. Two drill holes intersected V9W-2 vein at 169m and -61m elevation, grading 31 to 110 g/t Ag, 0.18 to 0.27% Pb, 1.49 to 5.59% Zn, 0.05 to 0.34% Sn over 0.11 to 0.19 m true thickness.Table 1: Selected Drill Hole Assay Results:Drill HoleIntersectionInterval (m)Ag (g/t)Pb (%)Zn (%)Sn (%)Mineralized VeinsFrom (m)To (m)ZK40603139.10140.251.154892.573.810.70V6190.93191.330.4011712.803.44<0.01V6-1ZK40202169.78170.230.45965.522.610.13V4ZK41003334.02335.601.58280.931.520.07V4368.73370.171.44272.804.490.07V4 77.6278.170.5514956.727.760.41V6-0ZK40604229.17229.600.433087.912.670.07V6243.59243.990.401490.0511.850.34V6-1ZK40203109.19109.590.406370.911.130.05V6136.66137.500.84460.681.520.03V6-1ZK410101270.70271.100.40460.042.720.71V4 147.90148.300.40331.8915.050.41V6-0ZK40605150.30150.700.40792.164.310.51V6-0308.09308.490.4024501.2911.650.14V6 25.6026.460.862631.411.670.05Not Named 178.76179.240.48390.051.840.03Not NamedZK410102181.73182.330.601290.123.350.05Not Named 203.77204.270.50870.154.410.55Not Named 218.80219.500.70361.204.410.09Not NamedZK41802144.57144.970.401273.081.610.04V4ZK101127.32127.720.40760.360.420.01V6ZK4260154.3655.030.67140.024.430.15Not NamedZK2406130.81131.210.40390.066.050.08V13 201.32204.453.134320.180.630.07V9W-2Including204.05204.450.4031200.953.670.38  208.39211.022.631080.193.130.06V9W-1Including208.39208.790.405121.135.140.11  223.94224.340.40320.017.130.06Not Named 231.20231.670.473242.634.380.17Not Named 106.44106.960.522763.472.620.03V8-2 118.18119.701.521080.151.160.05V8 203.43204.701.27610.214.570.05V14 227.57227.970.40640.472.710.19V13ZK2807329.37329.810.44360.035.490.23V9-1 350.53350.980.45521.583.120.14Not named 366.40367.140.741040.611.770.17Not named 382.25383.150.90250.480.910.15V9-0 428.85439.2110.36371.725.400.11V9ZK320873.4373.900.472160.383.310.08V8-0 285.46287.321.865252.451.550.07V14Including285.46286.020.5615957.903.970.16  295.40295.660.261170.200.360.04V13 406.47410.103.632051.496.530.64V9Including407.73408.600.873431.529.021.21  418.84419.190.351440.202.970.59Not Named 472.87476.043.171013.892.660.22V5Including472.87474.001.131728.383.530.30  544.90545.210.3120110.502.850.53V7 243.65244.000.352850.120.290.02Not Named 325.18325.410.23890.184.470.21V9 384.47384.740.27630.143.590.16V5-1 445.37445.560.19320.053.200.09V5 504.63505.110.481134.533.880.03Not NamedZK3608511.94513.421.48671.661.890.30V7-1 551.68555.293.61331.955.090.10Not Named 675.47675.690.22813.531.610.30Not Named 677.31677.650.341128.343.230.34V2-1 685.68686.691.0110.533.530.16V2-0 712.30713.341.04911.213.780.87V2 723.69724.340.65410.733.990.73V2-2 386.66388.611.95481.301.200.09V8 501.18502.030.852530.860.460.08V15ZK3209549.97550.570.601547.291.060.01V14 600.61600.790.18430.742.570.14V9-1 616.54617.140.603740.751.260.08V9-0ZK4005140.20142.432.231521.603.770.20V8Including140.20140.670.474202.298.560.80  226.60226.840.242030.2016.600.14V15-1 252.60252.930.33900.856.490.19V15-0 463.90466.752.852120.200.650.05V9/v10 265.41265.850.44560.652.520.05V15-1 294.97295.770.801120.100.120.01V15 327.36328.391.03260.723.310.13V13 353.39353.860.471033.242.560.15Not NamedZK200546.5046.670.17330.144.680.12V9-1 100.50100.680.181100.275.790.34V9W-2 105.81106.050.24551.182.030.22V9W-1 195.60196.821.221430.040.190.01V9 355.00355.220.225100.050.160.11V7-1 409.12411.412.29722.983.310.07V7-0 413.49416.142.65832.894.840.06V7-0Including414.37414.570.2027116.7011.850.16  475.32478.803.481166.865.570.23Not NamedIncluding477.22477.960.7428620.005.970.61  513.60514.661.06902.092.100.97V2-1ZK2808251.38254.923.541690.911.250.05V8-0Including253.25254.921.673371.882.070.06  391.73392.320.592591.781.25nullV8-2 399.90400.240.34321.073.430.04V8 424.01425.191.18821.457.450.23V15-1 506.05506.290.244582.814.180.38V13 581.17581.900.731651.132.070.20V9-1 795.47795.870.401750.260.210.05V7-1ZK120490.0990.330.2434312.501.630.10V9 515.61519.033.423052.482.030.34V6-0Including515.61516.871.265660.550.690.17  65.7067.121.421120.090.06<0.01V8-1 68.4069.380.981100.170.890.01V8-0 184.80185.350.5510602.060.520.04V8-2 197.20197.880.682520.661.670.04V8 231.96232.200.244700.750.500.05V15-1 239.80242.232.43650.233.160.53V15ZK2006320.20320.460.261210.5026.500.26V9-1 449.73450.370.644700.393.420.16V910.8411.030.191280.280.990.05V2ZK606295.83296.300.471711.481.970.10V5-1377.97379.031.061031.614.620.21V9389.04390.101.06830.358.260.41Not NamedDrill hole plans, cross sections and longitudinal maps of the veins are available on Silvercorp' s website at UpdateThe GC project mine and mill construction is well underway.

Drill cores are HQ, NQ, or BQ in size and drill core samples were taken from sawn half core for every 1.5 m or limited by apparent wall rock and mineralization contact. The samples are shipped directly in security sealed bags to ALS Chemex in Guangzhou, China (Certification ISO 9001), located approximately 180 km southeast of the GC property site.Sample preparation consists of drying, crushing and splitting of the sample to 250 grams, then the sample is pulverized to 200 mesh. Ag, Pb, and Zn in drill core samples were analyzed by aqua regia digestion and AAS. Tin was analyzed by fusing with peroxide, then leaching the melt and acidifying to precipitate out the tin for AAS finish. Check samples including field duplicates and pulps are routinely sent to the Sub-Institute of Analytical Chemistry, Beijing General Research Institute of Mining & Metallurgy, located in Beijing.Myles Gao, P.Geo., is the Qualified Person on the project as defined under National Instrument 43-101.
