VANCOUVER, British Columbia – Silvercorp Metals Inc. (“Silvercorp” or the “Company”) is pleased to report the gold assay results from the first eight underground drill holes at its newly acquired, 70% owned BYP Gold-Lead-Zinc Project in Hunan Province, Central China. These are initial results from the Company’s planned 50,000 metre (m) surface and underground drill program which is intended to upgrade the current historical resources and expand the mineralization bodies along strike and down-dip.

Currently four underground drill rigs are operating from underground tunnels developed within the # 3 gold mineralization zone at the 252m elevation, about 100 m below surface. The underground drills are performing infill drilling at 25 to 50 m spacing intervals within the #3 gold zone, and will test the #1 gold zone and #XII lead-zinc-gold zone located approximately 100 m beneath the #3 zone. Once further defined by the infill drilling, the #3 Gold zone will be the focus of initial mining.

In addition to the underground drilling, three surface drill rigs are carrying out step-out drilling to expand the known zones and to explore for new zones.

As of the end of April, a total of 2,634 m of drilling, including one surface hole and 15 underground drill holes, was completed. Assay results from the first eight infill underground drill holes were received and are listed in Table 1. As all the eight underground drill holes were drilled from the tunnels within the #3 gold zone, they all intercepted gold mineralization and highlights of significant gold intercepts are as follows:

ZK16-107 intercepted 69.5 m of 5 grams per tonne (g/t) gold (Au), including 7.21 m of 10.68 g/t Au;
ZK1702 intercepted 24.58 m of 5.55 g/t Au, including 10.23 m of 7.34 g/t Au;
ZK1703 intercepted 33.15 m of 4.34 g/t Au, including 14.83 m of 7.19 g/t Au;
ZK17-101 intercepted 47.29 m of 4.50 g/t Au; and
ZK17-105 intercepted 46.67 m of 4.61 g/t Au, including 10.7 m of 9.46 g/t Au.

A geological report on the property was completed by the Chinese government geological team in 1992. Based on 36,151 m of diamond drilling in 105 holes, the 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.  A qualified person has not done sufficient work to classify the historical estimates as current mineral resources, and Silvercorp is not treating the historical estimates as current mineral resources and the historical estimate should not be relied upon.

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 41m in true thickness as defined by surface drill holes occurs in the sandstone while lead and zinc mineralization zones up to 53m in true thickness are hosted in the limestones.  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 limestone.  Gold, lead and zinc mineralization zones appears from surface to a depth of about 350m based on the deepest drill holes.

Mill Upgrade and Other Updates on the BYP Project

Silvercorp has completed modification of the existing 400 t/d floatation mill by adding a cone crusher expanding the mill’s capacity to 500 t/d. The mill is in the process of tuning up by processing some lower grade gold ores recovered from underground tunneling. Initial mining, which is expected to commence by the end of May, will focus on some of the higher grade sections within the #3 Gold zone. The BYP mine is expected to produce and mill 130,000 tonnes of ore at a grade of 7 g/t gold in the current fiscal year.

The Company has also contracted a qualified Chinese engineering firm to design an expansion of mining and milling capacity at the BYP to 2,000 t/d (1,000 t/d gold mineralization and 1,000 t/d lead-zinc mineralization) by fiscal 2014.

Quality Control

The Company maintains a quality control program to ensure best practices in sampling and analysis of the samples. Drill cores are NQ in size and drill core samples were taken from sawn half core for every 2.0 metres or limited by apparent wall rock and mineralization contact or faults. The samples were shipped directly in security sealed bags to ALS Chemex Laboratory in Guangzhou, Guangdong Province, China (Certification ISO 17025) for assay.

The ALS Chemex Lab in Guangzhou uses a standard fire assay fusion-AAS finish procedure to analyze lower grade samples from 0.005 to 10 g/t Au, and fire assay fusion-electronic analytical balance method to analyze high grade samples from 0.05 to 1000 g/t Au.

Myles Gao, P. Geo, Silvercorp’s president, is the Qualified Person on the project as defined under National Instrument 43-101.  He has verified the information and has reviewed and approved the contents of this news release.
