SILVERCORP ACQUIRES HIGH GRADE XHP SILVER-GOLD-LEAD-ZINC PROPERTY IN
LUOYANG, HENAN PROVINCE, CHINA

VANCOUVER, British Columbia – November 21, 2011 – Silvercorp Metals Inc.
(“Silvercorp” or the “Company”) announced that through its 77.5% own subsidiary Henan Found
Mining Co. (Henan Found), it has signed a share purchase agreement to acquire a 100% equity
interest in the SX Gold Mining Company (“SX Gold”), a Luoyang City government controlled
company. SX Gold operates the XHP silver-gold-lead-zinc mine which includes a 14 squarekilometre mining permit and a 500-tonne-per-day flotation/CIL mill (collectively called as “XHP
Project”). The share purchase agreement was signed after Henan Found won a public tendering
process arranged by the Luoyang City government to sell SX Gold.
The XHP mine is located about 120 kilometres southeast of the Company’s Ying mine, a threehour drive from both Luoyang City and the Ying mine, and six kilometres to the northwest of the
XBG mine that was acquired in August 2011. In addition, SX Gold also owns the HGDG gold
exploration permit of 4.45 square kilometres and owns a 51% interest in the PLS gold exploration
permit covering 3 square kilometres. A map showing the relative location of the properties will
be posted on Company’s website.
XHP Transaction
The total acquisition consideration payable by Henan Found for SX Gold is approximately
US$22.75 million. A payment of $19.6 million has already been made, with the balance due
upon completion of the share transaction and the transfer of the mining and exploration permits to
Henan Found.
Over the last two years, SX Gold has focused on mining oxidized gold ore near surface. The
oxidized ores were treated by the 500 tonne-per-day CIL circuit to recover gold only. Last year, a
flotation circuit was installed to recover lead-silver concentrate from the partially oxidized silvergold-lead-zinc ores after gold is recovered through the CIL circuit. Mill recoveries were reported
as 75% for gold, 70% for silver, and 60% for lead.
During 2011, SX Gold records show approximately 50,000 tonnes of less oxidized silver-goldlead-zinc ores were mined from Vein K13 at the 577metre (m), 540m, and 500m levels through
main access tunnel PD1 at XHP East. The ores were stockpiled as the CIL circuit could not
recover gold from these less oxidized ores, whereas, the existing flotation circuit can only recover
silver-gold-lead to concentrate and a second floatation circuit is required to recover zinc to zinc
concentrate.
Silvercorp intends to resume mining activities at the XHP mine to stockpile ores pending
installation of a second flotation circuit to enable the mill to generate a gold-silver-lead
2
concentrate and a zinc concentrate. The mill upgrade is expected to be completed and in
operation by February 2012.
Silvercorp will also carry out an exploration program immediately, including tunneling and
surface and underground diamond drilling, with a goal of defining a NI43-101 compliant mineral
resources. The program is expected to be self-funded through cash-flow s from mine operations.
This acquisition of the XHP project, together with the acquisition in August 2011 of the XBG
Mine, furthers Silvercorp’s intent to consolidate (through Henan Found) the mines and
prospective projects in the high grade silver, gold and base metal belt in the Southwest Luoyang
City district. Silvercorp has established itself in the region as an effective explorer and developer,
with a good brand name and has become the largest non-state-controlled company and one of the
top tax payers in Luoyang City. This has been instrumental in gaining and building the full
support of city, county and provincial governments.
Together, the XHP and XBG Mines establish the fourth base for Silvercorp to grow its production
and mineral resources in China.
Historical Exploration and Mining Activities
Geologically, the XHP project area is situated in the east extension of the Qinling Mountain belt
near the margin of the Northern China craton in the same regional mineralization belt as the Ying
mining camp. This is one of the largest silver-gold and base metal belts and largest silverproducing region in China. The XHP project area is underlain by Middle Proterozoic andesite
flows interbedded with minor thinly bedded rhyolite, which has been intruded by Mesozoic
granitic stocks. Mesothermal-style silver-gold-lead-zinc mineralization is hosted by northnortheast-, northeast-east- and northwest-trending ductile shear structures which occur along a
southeast margin of large granitic plutons that extends over 40 kilometres long and feature
extensive overlapping silver-lead-zinc-gold soil anomalies.
Exploration results are as reported in the records of SX Gold, which have been reviewed by a
team of Henan Found’s geologists who visited the property three times from October 2010 to July

  1. During the site visits, a total of 16 check samples were collected and assay results are listed
    at the bottom in Table 3. The check assays are consistent with deposit grades reported by SX
    Gold. The exploration results reported below are compiled from the records of SX Gold on
    historical exploration results and mining production, which Silvercorp believes to be reliable.
    The XHP project area is divided into XHP West and XHP East, which is separated by a third
    party’s gold mining permit (Dianfang Gold Mine, reported containing approximately 300,000
    ounces of non-NI 43-101 compliant gold resources). There are 11 silver-gold-lead-zinc veins
    (veins K5, K6, K7, K8, K10, K13, K13-1, K16, K17, K18, and K21) at the XHP East while at the
    XHP West, there are 7 gold-silver-lead veins (veins K1, K2, K3, K9, K11, K12, K23) and one
    gold eruptive breccia pipe (K9). There mineralized veins and eruptive breccias pipe were
    identified by surface mapping, underground tunneling and surface diamond drilling.
    Mineralization is hosted in a set of quartz-sericite-chlorite-carbonate veins cross-cutting
    Proterozoic age mafic volcanic flows. The system consists of quartz-carbonate veins with silvergold-lead-zinc mineralization trending NNE, NEE, N-S, and NW with a steeply (51-89°) dip and
    extend a few hundred meters to over 2,000m along strike and up to 450 m along the dipping
    direction with true width ranging from 0.1 to 6.5 m for the veins and 1.0 to 20 m for the eruptive
    3
    breccia pipe. SX Gold exploration records show the veins contained 20 to 1,224 grams per tonne
    (g/t) silver (Ag), 0.10 to 11.17 g/t Au, 0.50 to 27.47% Pb, and 0.30 to 12.09% Zn.
    The XHP property area has experienced artisanal mining for gold and silver dating back to the
    late 1990s. SX Gold’s mining activities were mainly carried out on four main veins: K2, K3, K11,
    and K13. At the XHP West, there was a total of 130,000 tonnes of gold-silver-lead ore mined
    from the veins K2 and K11 at the 600m, 550m, and 518m elevations through adits PD600, PD550,
    and PD518. About 25,000 tonnes of gold-silver ore was mined out on the K3 vein.
    Tunneling exploration was carried out on veins K2, K11, K3, K5, K9, K10, K13, K13-1, K16,
    K18, K21, K22 and K23 through 21 adits throughout property. However, most of the tunneling
    exploration was done on veins in which significant mineralization was intersected, being K2 and
    K11 (4,783 m), K13 (4,894 m), K18 (1,508m), K13-1 (720 m), K5 (947 m). Tunneling on veins
    K2 and K11 was mainly at 600m, 550m, 518m, 478m, and 438m elevations. For Vein K13,
    drifting along the vein was carried out at 610m, 577m, 540m, 500m, and 460m elevations. The
    most significant tunneling intersected continuous Au-Ag-Pb-Zn mineralization over 91 m, which
    contained 171 g/t Ag, 0.41 g/t Au, 4.23% Pb, and 3.10% Zn over 0.94 m true width.
