Silvercorp Metals Inc.: Tunnel Intercepts 0.85 Metres of 5,685 Grams per Tonne Silver, 10% Lead and 5.4% Zinc in S8 Vein, Ying Silver Project, Henan Province, China

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Nov. 14, 2005) - Silvercorp Metals Inc. ("Silvercorp") (TSX VENTURE:SVM) is pleased to report that continuous tunneling at the Ying Silver Project has exposed significant new massive galena sheets with bonanza grade silver (Ag), lead (Pb), zinc (Zn) and copper (Cu) mineralization in the S8 vein. Exploration on the Ying Project is carried out through Silvercorp's 77.5% subsidiary, Henan Found Mining Co. Ltd., a Sino-foreign joint venture company which holds 100% of the Ying Project and operates under a 30 year business license.

As reported August 2, 2005, the S8 is a newly intercepted bonanza grade vein that has not been included in the April 18, 2005 NI 43-101 resource estimate. Over the last three months, 1,121 metres ("m") of drifting and raises have be developed along the S8 vein and several bonanza grade massive galena sheets have been exposed.

The most significant intervals include:

- 5,686.5 grams per tonne (g/t) (182.8 oz/t) Ag, 10% Pb, and 5.4% Zn over 0.85m true width;

- 4,001.4 g/t (128.86 oz/t) Ag, 15.76% Pb and 3.69% Zn over 1.05m true width; and,

- 2,766 g/t (88.94 oz/t) Ag, 35.25% Pb, 6.47% Zn, and 2.03% Cu over 1.1m true width. This is the first copper mineralization occurrence (as coarse chalcopyrite) in the SGX area.

The S8 vein is oriented southwest/northeast and based on surface trenches and limited tunnels, has been mapped out over 4,500m and to a minimum depth of 275m, dipping northwest. The vein has been the subject of previous mining activity in many sections at different levels to a depth of 150m from surface. The S8 vein is currently being explored through three access tunnels at the SGX camp: CM101 on the 640m elevation, and CM102 and CM103, both on the 570m elevation. A total of 222.6m tunneling and 86.2m of raises have been completed so far through CM102, which has intercepted and is following the S8 vein. In a further 38m and 250m, respectively, CM101 and CM103 are also expected to intercept the S8 vein.

The S8 vein is also being explored through two access tunnels about 2 km north of CM102 tunnel at the YLG camp: YPD02 (565m elevation) and YM01 (585m and 550m elevations). In access tunnel YM01, the S8 vein is being explored at two elevations. At the 550m elevation, 250m of drifting has been completed along the vein, while at the 585m elevation, a total of 252m of tunnelling has been drifted along the vein. The second access tunnel, the YPD02 decline tunnel, from 565m to 510m elevations, has just intercepted the S8 vein with 0.4m thick massive galena sheets with assay results pending.

To date, out of 1,121m of drifts and raises completed along the S8 vein 438m are massive galena sheet with grades over 1,250 g/t Ag-equivalent, representing a 38% rate of mineralization.

Assay results for the S8 veins are listed in the Table below:

The 2005 Exploration and Development Program is ahead of schedule As a result the Company has announced that it is accelerating to the 2006 program by mobilizing two drill rigs to commence a 10,000m deep drilling program aimed at testing the continuation of mineralization and vein structure below 350m from surface.

Quality Control

The Company has implemented a quality control program to ensure best practice in sampling and analysis of the tunnel samples. Rock samples were collected by channel sampling the face of the undercut drifts. The channels were usually cut 10 cm in width and 5 cm in depth producing a sample weighing approximately 2 kg to 10 kg for each 0.10 to 1.00m interval depending on the thickness of mineralization. Drill cores are NQ size and drill core samples were taken from sawn half core limited by apparent massive galena sheet contact. The samples are shipped directly in security sealed bags to the Langfang Institute of Geochemical and Geophysical Exploration (Certification ISO 9001), a well-regarded analytical laboratory in Langfang, Hebei Province, approximately 60 km from Beijing.

The sample preparation consists of drying, crushing, splitting of the sample to 150 grams, then the sample is pulverized to 200 mesh. Ag, Pb and Zn were analyzed by a 3 hour hot aqua regia digestion on 30 gram samples with an AA finish. Check samples including field duplicates and pulps are routinely sent to ALS Chemex Laboratories in Vancouver, Canada.

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