Jul. 5, 2011 (Marketwire Canada) --
VANCOUVER, BRITISH COLUMBIA -- Silvercorp Metals Inc. (TSX:SVM)(NYSE:SVM) (the "Company") reports the results of a National Instrument ("NI") 43-101 Technical Report (the "2011 Resource Report") dated June 15, 2011 by Randal Cullen, P. Geo. (Qualified Person) on the BYP gold-lead-zinc project in Hunan Province, China. The Resource Report presents the resource estimates for the gold, lead, and zinc metals at the BYP Project and is available for review on the SEDAR system and on the Company's website at www.silvercorp.ca.
The 2011 Resource Report estimates that the Indicated category resource is 225,400 ounces of gold and the Inferred category resource includes an additional 208,000 ounces of gold, 111,272 tonnes of lead and 283,964 tonnes of zinc. It is based on historical exploration data and the Company's recent underground channel sampling program. The 2011 Resource Report, however, did not include the significant underground drill results released by the Company on May 5, 2011.
The historical geological report on the property was completed by a Chinese government geological team of Hunan Province in 1992, based on 36,151 m of diamond drilling in 105 holes. The historical geological report defined 5.44 million tonnes of gold mineral resources grading 2.76 g/t Au, containing 482,000 ounces of in situ gold, and 3.12 million tonnes of "higher grade" lead and zinc mineral resources grading 2.45% Pb and 5.26% Zn, containing 76,400 tonnes of lead and 164,112 tonnes of zinc. Silvercorp is not treating the historical estimates as current mineral resources and the historical estimate should not be relied upon.
Resource Estimates from the 2011 Resource Report
Using the base case of 1.0 gram per tonne (g/t) and capped gold values at 11.43 g/t, the gold (Au) resources are estimated to contain an Indicated resource of 2.14 million tonnes grading 3.27 g/t Au, containing in situ 225,400 ounces (oz) of Au and an Inferred resource totaling 2.82 million tonnes grading 2.29 g/t Au, containing in situ 208,000 oz of Au (Table 1). The estimate used a 0.1 g/t Au cutoff.

The resource estimate for lead (Pb) and zinc (Zn) is all in the Inferred category due to drill spacing and lack of auditable survey data. The resource comprises 8.31 million tonnes grading 1.34% Pb and 3.42% Zn for the base case of 3% Pb+Zn cut-off grade. The estimation results are presented in Table 2.

Geologically, the project area is underlain by Devonian limestone, mudstone, and sandstone units that were intruded by Mesozoic granites within the prominent Central Hunan gold-tin-lead-zinc-antimony polymetallic belt. Gold mineralization up to 41 metres in true thickness as defined by surface drill holes occurs in the Devonian aged sandstones adjacent to a major basal thrust zone, whereas lead and zinc mineralization zones up to 53 metres in true thickness is hosted in thickly bedded Middle Devonian carbonates. This lead-zinc resource is locally imbricated with the gold resource along younger thrust planes, juxtaposing and in places coalescing the two mineralization types.
Gold mineralization is mainly related to silisification, fine quartz veining, and disseminated pyrite developed along joints and fractures in fine grained sandstones. Lead and zinc is usually very fine-grained and is associated with silicification and pyrite in dolomitic limestones. Gold, lead and zinc mineralization zones appears from surface to a depth of about 350m based on the deepest historical drill holes.
The Company's planned 50,000 metre 2011 drilling program will carry out in-fill drilling to confirm and upgrade the historical resources, complete step-out drilling to test depth and strike extension of gold, lead and zinc mineralization, and test several new target areas. Three surface drill rigs and four underground drill rigs are employed to accomplish the task. Since May, 2011, six surface drill holes of up to 700 metres in depth and 12 underground drill holes have been completed. Cores were cut and assay results are pending.
Randal Cullen P.Geo., Qualified Person as defined by NI 43-101, has reviewed and consented to this press release and confirmed that it fairly and accurately represents the information in the Technical Report that supports the disclosure.
Myles Gao, P.Geo., President and Chief Operating Officer of Silvercorp, is the Qualified Person for Silvercorp under NI 43-101 and has reviewed and given consent to this press release.
