Silvercorp Announces Positive Pre-Feasibility Study for the GC Silver-Lead-Zinc Project in Guangdong Province, China

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 31, 2012) - Silvercorp Metals Inc. ("Silvercorp" or the "Company") (TSX:SVM)(NYSE:SVM) is pleased to announce it has received a positive Pre-Feasibility Study ("PFS") for its 95%-owned GC Project in Guangdong Province, China. The PFS was prepared by independent consulting firm AMC Mining Consultants (Canada) Ltd. ("AMC").

"The Company has already commenced construction at the GC Project and initial production is expected to commence in the 3^rd quarter of calendar year 2012," said Rui Feng, Silvercorp's Chairman & CEO. "We are pleased that Proven and Probable Reserves at the GC Project have been established for the first time, and the PFS also reconfirms the project's robust economics."

Highlights of the Pre-Feasibility Study

• Defined mineral reserves of 4.8 million tonnes in the Proven and Probable categories grading 121 grams per tonne (g/t) silver (Ag), 1.31% lead (Pb), and 2.95% zinc (Zn), containing approximately 18.5 million ounces (oz) silver, 62,100 tonnes of lead, and 140,200 tonnes of zinc, supporting a project life of 12 years.

• Net Present Value ("NPV") was estimated to be $73.7 million (at an 8% discount rate) with an IRR of 33% and payback in 2.4 years; and,

• An initial capital cost of $67.4 million and total operating cost of $40.60/ per tonne milled.

In preparation for production, a 1,500 tonne per day (tpd) (rising to 1,570 tpd after five years) mining capacity and 1,600 tpd flotation milling capacity facilities are under construction. The flotation mill is designed to generate silver-lead, zinc, and pyrite concentrates. The optional gravity tin recovery circuit can be appended to the main circuit to recover tin from tailings.

Mineral Resource and Reserve Summary

Mineral Resources: AMC estimated Measured and Indicated Resources totaling 7.63 million tonnes grading 122 g/t Ag, 1.32% Pb, and 3.08% Zn and Inferred Resources totaling 7.96 million tonnes containing 123 g/t Ag, 1.41% Pb, and 2.66% Zn, as detailed in the Table below, which does not include any of the results of the Company's 2011 surface drilling program at the GC Project announced on January 17, 2012.

Mineral Reserves: The PFS defined mineral reserves of 4.8 million tonnes in the Proven and Probable categories containing approximately 18.5 million oz. silver, 62,100 tonnes of lead, and 140,200 tonnes of zinc with a projected mine life of 12 years.

* Ag Eq (g/t) is the recovered silver equivalent using metal prices of US$18.00/ troy oz Ag, US$1.00/lb Pb, US$1.00/lb Zn and Recoveries of 62.78% Ag, 84.57% Pb and 88.42% Zn, and calculated using the formula AgEq Recovered = {Ag (g/t) x Ag ($/g) x Ag (Rec%)} / Ag ($/g) + {Pb (%) x Pb ($/lb) x Pb (Rec%) x 22.0462} / Ag ($/g) + {Zn (%) x Zn ($/lb) x Zn (Rec%) x 22.0462} / Ag ($/g)

** 135 g/t Ag Eq cut-off for Stope Reserves & 45 g/t Ag Eq for Development Reserves.

Rounding of some figures may lead to minor discrepancies in some totals

The reserves were estimated by converting Measured and Indicated Resources for 21 out of 25 veins occurring between the +100 mRL(1) and -300 mRL elevations. For mine design reasons, the PFS did not include approximately 2.5 million tonnes of Measured and Indicated Resources above the +100 mRL elevation (as the mineability of this material has yet to be fully assessed), and below -300 mRL down to -535m elevation, (as -300 mRL is the lower limit of the current mine design).

Economics

AMC has estimated a Base Case Net Present Value ("NPV") for the GC project of $73.7 million (at an 8% discount rate), an internal rate of return (IRR) of 33% and payback of capital expenditures in 2.4 years. These economic metrics are positive and demonstrate that the project is robust in the face of the possible scenarios that typically impact on a mining operation.

The metal prices used in the AMC financial model are shown in the table below.

	2012	2013	2014	2015	After 2015
Silver (US$/oz)	40.00	30.00	25.00	18.00	18.00
Lead (US$/lb)	1.11	1.16	1.14	1.15	1.00
Zinc (US$/lb)	1.05	1.12	1.11	1.15	1.00

Foreign exchange rate was set at USD:RMB of 6.35.

Mine Design & Mining Method

The design strategy is two staged with Stage 1 being predominantly mechanized development to fast track production while the longer term Stage 2 at depth reverts to conventional tracked development methods. The Stage 1 Ramp is a 4.2 m x 3.6m in profile, 2,224 m in length and access is from +176 mRL down to -64mRL. The Stage 2 Main Shaft is 6.0 m in diameter and 618m in depth. The main shaft collar is at +248 mRL and sump bottom is at -370 mRL. Silvercorp will utilize the Shrinkage and Resue stoping mining methods at the GC Project, the same methods Silvercorp uses at its Ying Mining Camp.

Production

An Environmental Permit and 30-year Mining License were received in 2010 and Silvercorp is currently in the process of constructing the mine. Initial production is expected to start in the third quarter of 2012 with full capacity of 1,500 tonnes per day expected to be achieved in 2013. The following table summarizes the Life of Mine production and ore grades for the GC Project.

Processing Facility

The processing plant is designed for 1,600 tpd flotation mill process consisting of a standard sequential flotation of lead, zinc and pyrite with three-stage cleaning of the lead and zinc concentrates and single stage cleaning for pyrite. An optional tin gravity recovery circuit potentially can be appended to the main circuit to recover tin in the tailings. Concentrates are dewatered by conventional thickening and filtration. The final products are lead, zinc, and pyrite concentrates, with a possible tin concentrate. Payable silver is in the lead concentrate.

Permitting

Silvercorp has received all permits required for commencement of construction of the mine, including Environmental and Mining Permits. Once completed, production can commence from the GC mine upon receipt of the following permitting measures:

- completion of a review of the health and safety production measures by the Guangdong Provincial Safety Production Bureau ("GPSPB");

- a post-construction safety measure inspection by GPSPB to ensure the mine, mill and tailing facility has been built to the "Mine Design" in terms of safety measures; and

- an inspection of the tailing facility, mill, and other engineering works by the Guangdong Environmental Bureau.
