1 | SUMMARY

AMC Mining Consultants (Canada) Ltd (AMC) was commissioned by Silvercorp Metals Inc. (Silvercorp) to review a mineral resource estimate prepared by Silvercorp and to provide Silvercorp with an independent technical report compliant with Canadian National Instrument 43-101 (NI 43-101) on the GC (Gaocheng) Ag-Zn-Pb Project in Guangdong province, China.

The technical review was conducted in two phases:

- Phase 1 – AMC Principal Geologist Brian O’Connor undertook a site visit during the period from March 27 through March 30, 2009. Inspection of the properties, laboratories and relevant data was conducted. Interviews with related technical personnel and the collection of check samples were also undertaken.

- Phase 2 – Complete a draft of the technical report for Silvercorp’s review and comment to be followed by a finalised report.

Silvercorp is exploring the GC Ag-Zn-Pb property through its 95%-owned joint venture company, Yangtze Mining Ltd. Silvercorp acquired a 95% ownership of the property in April, 2008. The GC Ag-Zn-Pb is an advanced exploration project and the subject of an April 2008 Technical Report prepared by SRK Consulting Engineers and Scientists.

Subsequent to the 2008 Technical report, Silvercorp undertook an exploration program summarized in Table 1.1. The results from the diamond drilling have been incorporated in the updated Resource estimate. The soil sampling program resulted in the identification of three new Ag-Zn-Pb anomalies on the southern part of the property where no drilling had been previously conducted. A full list of the historical exploration programs is presented in Table 6.1.

Table 1.1 2008 Exploration Program

Program Type | Unit of Measure | Units
1:10,000 Soil Profiling | km | 10
Diamond Drilling | m | 10,083
Trenching | m3 | 740
Soil Samples | sample | 535
Chemical Analysis | sample | 2,139

The terms and conditions of the exploration permit for the GC property allowed for diamond drilling and trenching to be used as exploration tools, but the use of explosives on the property was not allowed until a mining permit had been issued. Silvercorp had recently completed the application process for the mining permit at the time of the site visit. AMC was informed by Silvercorp that approval was expected between July and December of 2009. The collection of bulk test material and exploration drifting to and on the mineralized veins would be allowed at that time.

Guangdong Province, People’s Republic of China

AMC reviewed the geology of the project, reviewed and verified a resource estimate completed by Silvercorp’s geologists, and believes that further work to advance the project is warranted.

Geologically, the project area is located in the north-eastern margin of Luoding Basin, the middle portion of uplift in the Hua’nan (South China) Fold System. The deposit occurs on the intersection of a north-easterly striking fault zone and a near east-westerly striking fault zone. North-east striking structures and arc structures form the basic geological framework of the region. Outcrop include Late Proterozoic Sinian sedimentary clastics and carbonate rocks, which host Ag-Pb-Zn polymetallic deposits in the region, Paleozoic Ordovician, Silurian, Devonian and Carboniferous sedimentary clastics and carbonate rocks which host some Cu-Pb-Zn, Mn and Au-Ag deposits, Mesozoic / Triassic coal-bearing clastics rocks, and Cretaceous red clastics rocks. Intrusive rocks occur in the central area of an arc/ring structure, include Paleozoic granite batholiths, and Mesozoic granite stocks and dykes. The stocks and dykes intrude in the inner zone of the arc/ring structure, and are closely related to the Ag-Pb-Zn polymetallic mineralization in the region.

The mineralization on the GC property is structurally controlled occurring in veins formed along fault traces which are enveloped by an alteration zone. The alteration zone may reach a few metres from the vein occurring in both the hanging and footwall. There are a total of 27 Ag-Zn-Pb veins identified on the GC property; they are divided into two groups – the NWW striking and NE striking. There are 23 of the NWW-striking group which typically dip toward SE at an angle of 60-85°. They are numbered from V2 through V9 and V13 through V15. A number of the veins have a subset designation. The four NE-striking veins (with subset designations) are numbered from V10 through V12 and typically dip to the southeast at an angle of 60-75°. The vein V12 is not included in the Resource estimate. In addition vein V15 was not included in the 150 g/t AgEq Resource estimate. The main mineralized veins are series V2, V6, V7 and V9. These vein series represent 83% of the Measured and Indicated Resource in terms of tonnes. The vein series V2 represents 53% of the measured and indicated resource in terms of tonnes.

Prior to Silvercorp’s acquisition of the GC Property, illegal mining activity produced several tunnels on the property and the extraction of mineralized material. The Guangdong Institute of Geological Survey (GIGS) developed 66m of tunnel in 2002. The tunnelling intersected the V5 and V5-1 veins with minor Ag-Zn-Pb mineralization enveloped by alteration haloes ranging from 0.6 to 1.8 m wide. The quantity and quality of the mineralization extracted has not been reconciled. Details of the underground workings are recorded in Table 6.3. Yangtze Mining mapped and sampled the tunnels where accessible. Assay results of the tunnel samples were used in resource estimation. AMC visited the tunnel adits but the entrances to the tunnels were blocked with barricades. The extracted mineralization has not been accounted for in the Resource estimate.

In order to optimise a processing flowsheet for the recovery of lead, zinc, silver, tin and sulphur from the GC mineralization, the Hunan Non-ferrous Metals Research Institute (HNMRI) was contracted to perform mineral processing and metallurgical tests in February through April of 2009. The test sample was a composite of 158 drill core sample rejects from 2008 drill program. A summary table of the results is listed below in Table 1.2.

Table 1.2 Mineral Processing and Metallurgical tests as of April 2009

Product | Weight (%) | Grades | Recovery Rate (%)
Pb (%) | Zn (%) | S (%) | Ag (g/t) | Pb(%) | Zn(%) | S(%) | Ag(%)
Lead Con. | 2.63 | 46.35 | 9.53 |  | 3009.23 | 84.57 | 7.75 |  | 62.77
Zinc Con. | 5.84 | 0.92 | 48.95 |  | 268.4 | 3.73 | 88.42 |  | 12.43
Sulphur Con. | 14.65 | 0.81 | 0.41 | 42.52 | 189.74 | 8.23 | 1.86 | 61.31 | 22.05
Tailing | 76.88 | 0.065 | 0.083 |  | 4.5 | 3.47 | 1.97 |  | 2.74
Ore | 100.00 | 1.44 | 3.23 | 10.16 | 126.07 | 100.00 | 100.00 |  | 100.00

To demonstrate a reasonable prospect for economic extraction a cut-off grade of 150 g/t silver equivalent (AgEq) was applied to the Resource blocks. The AgEq equation included the recovery rates for silver, lead and zinc as described in Table 1.2 with the exception of the benefit of sulphur in concentrate, was not included in the AgEq, but the saleable portion of the silver contained in a sulphur concentrate was. In addition to silver, lead and zinc mineralization the GC deposit has tin mineralization that is not insignificant. Further study is required prior to a decision on the economic recovery of tin, thus tin was not used in the AgEq equation for this report.

Silvercorp employed the polygonal method to estimate mineral resources for the GC property, the same method used at its other operations in China. Details of the methodology are discussed in detail in Section 17. The Mineral Resources at a recovered silver equivalent cut-off grade of 150 g/t are summarized below in Table 1.3 and Table 1.4. The AgEq formula and price assumptions are discussed in detail in Section 17.

AMC is of the opinion that Silvercorp has sufficient drilling and sampling and has completed adequate bench scale metallurgical testing to complete a prefeasibility study or begin a feasibility study on the GC Project. The study would include a mine design based on the resource model, an investigation regarding a suitable scale of operation as well as preliminary studies completed on geotechnical, environmental, and infrastructure requirements. Cost estimates based on factored or comparative prices should be researched and applied to the Resource blocks in the Resource model for Resource to Reserve conversion parameters.

Silvercorp has a good understanding of the geology and mineralized trends on the property. AMC notes that the veins outlined to date have not been closed off by drilling and it is anticipated that ongoing exploration will continue to increase the overall resource and upgrade the classification of known resources.

Mineral Resources estimates were prepared by Silvercorp and reviewed and classified by AMC following CIM best practices. The result of the update was an increase of 250% in the sum of the Measured and Indicated Resources for the project.

As of May 2009, Silvercorp has made the following progress in applying for a mining permit and advancing the project towards production:

- An Environmental Assessment Report was completed in March 2009 and passed a review by an expert panel appointed by the Environmental Production Bureau of Guangdong. Pending receipt of the final approval, a mining permit application can be submitted to the Ministry of Land and Resources of China in Beijing.

- Silvercorp has engaged a Chinese engineering firm with Class A qualifications in mine and mill design to provide a full mine and mill design for the project.

Silvercorp’s mining experience includes majority ownership of four mines in the Ying Mining District of Hunan Province in central China held in two Sino-Foreign Cooperative Joint Venture companies. In addition, Silvercorp owns and operates two flotation mills in the Ying Mining District.

The company has budgeted approximately $4 million for the GC Project in 2009 (fiscal 2010) for exploration, mine and mill designs, permitting, associated reports and reporting. The exploration program will be composed of approximately 3,000m of diamond drilling. A Chinese firm has been engaged for the mine and mill design.
AMC has reviewed Silvercorp’s exploration and development plans and budget and is of the opinion that they are well conceived and appropriate to the stage of the project. AMC recommends Silvercorp conduct the program as proposed subject to funding and any other findings or events during the exploration and design phase. AMC makes the following recommendations with respect to resource estimation:

1) | AMC would recommend that Silvercorp undertake variography studies to refine the understanding of the grade distribution and utilize a kriging or inverse distance weighting approach to grade interpolation prior to future resource and reserve estimations.
2) | Continue the wax immersion bulk density measurements and continue to analyse the data on a vein by vein basis. AMC would suggest a sulphur or sulphide analysis as a basis for the bulk density assumptions.
3) | Carry out further studies into the potentially economic Sn and S components of the milling process.
4) | Carry out further metallurgical and mining studies into the oxidized zone prior to a future resource and reserve estimation.
5) | Consider the use of either electro-magnetic or induced polarization/resistivity surveys to help predict the orientation and extent of the structures bearing pyrite and/or galena.
6) | AMC recommends that the underground workings be reopened once the mining permit has been granted and that consideration be given to collecting a bulk sample and undertaking a test mining program.

2 | INTRODUCTION

AMC Mining Consultants (Canada) Ltd (‘AMC’) was commissioned by Silvercorp Metals Inc . (‘Silvercorp’) to review and examine the latest resource data on the GC Ag-Zn-Pb Project in China prepared by Silvercorp’s geological staff.

In 2008, Silvercorp undertook a 10,082.6m diamond drill program which represents 43% of all the recorded drilling on the property. The Silvercorp geological staff updated the geological model for the property and re-estimated a Mineral Resource with the inclusion of the findings of the 2008 data. The result of the update was an increase of 250% in the sum of the Measured and Indicated Resources for the project.

The review of the GC Project was based on published material researched by AMC, as well as data, professional opinions and unpublished material submitted by the staff of Silvercorp Metals Inc. or its subsidiaries. Much of the data came from reports prepared and provided by Silvercorp. The review of the resource estimation parameters was conducted both during the site visit to the GC Project and during the audit of the resource estimate in May, 2009. A previous report on the project was completed by SRK Consulting Engineers and Scientists (‘SRK’) for Silvercorp on the GC (Gaocheng) Ag-Zn-Pb Project and the Shimentou Au-Ag-Pb-Zn project in 2008. SRK prepared a NI43-101 technical report dated April 2008 (Dr. Anson Xu et.al. 2008).

Mr. Brian O’Connor, Principal Geologist of AMC, visited the GC property in order to review and act as the Qualified Person for a NI 43-101 compliant Technical Report providing an update on the project and resource estimate. The new resource estimate includes resources newly identified after Silvercorp acquired the property. From March 27th through March 30th, 2009, Mr. O’Connor visited the GC Project. During his visit, Mr. O’Connor reviewed exploration data and drill cores, visited drill exploration sites, surface trenches, outcrops and adits. In addition, Mr O’Connor completed a site visit of the ALS Chemex assay facility. The principal focus of the site visits was to examine and audit the current resource information.

All currency amounts and commodity prices are stated in US dollars. Quantities are stated in metric (SI) units. Commodity weights of measure are in grams (g) or percent (%) unless otherwise stated. Table 2.1 contains a glossary of terms and abbreviations.

This report includes the tabulation of numerical data which involves a degree of rounding for the purpose of resource estimation. AMC does not consider any rounding of the numerical data to be material to the project.

3 | RELIANCE ON OTHER EXPERTS

AMC in preparing this report has relied on various geological maps, reports and other technical information provided to AMC by Silvercorp. AMC has reviewed and analysed the data provided and drawn its own conclusions augmented by its direct field observations. The key and relevant information used in this report is listed in the References chapter at the end of this report.

Much of the original information was in Chinese, prepared by Mr. Qiang Wang, Chief Geologist of Anhui Yangtze, and his staff. Translations of key and relevant technical documents and data into English were done by Mr. Hongen Ma, M Sc. (Geology), and Mr. Myles Gao, P Geo. Both are fluent in Chinese and competent in English. Legends and other text on many of the maps were translated by Bei Sun, a bilingual draftsperson for Silvercorp. The author believes the translations to be credible and generally reliable but cannot attest to their absolute accuracy.

Silvercorp’s internal technical information reviewed by AMC was adequately documented, comprehensive and of good technical quality. It was gathered, prepared and compiled by competent technical persons. Silvercorp’s external technical information was prepared by reputable companies and AMC has no reason to doubt its validity.

While AMC has reviewed the documents and agreements provided by Silvercorp under which it holds title to the GC Project we do not offer an opinion in these areas. We are not experts in land, legal, environmental and related matters and therefore we have relied (and believe there is a reasonable basis for this reliance) in this report on Silvercorp who contributed the information regarding legal, land tenure, corporate structure, permitting, land tenure and environmental issues, property description and location.

4.2 | Mining Permit

In compliance with Chinese regulations for obtaining a mining license, a Chinese qualified agent, the Guangdong Geological Survey Institute (GGSI) has also prepared a Geological Report on the GC Permit dated September 30, 2007. The report summarizes the geology and exploration of the GC permit, and contains a resource estimate conducted in accordance with Chinese Resource Standards. The GGSI resource estimate was accepted by the Mineral Resources and Reserves Examination Center (MRREC) of the Ministry of Land and Resources PR China (MLR) based in Beijing which issued a "Resource Estimate Confirmation Letter" on December 24, 2007, which has, in turn, been accepted for filing by the Department of Land and Resource of Guangdong Province, thus allowing Anhui Yangtze to apply for a mining license on the GC Permit, based on the resource estimate.

Silvercorp has progressed on the mining permit application for the GC Project. The key reports required for applying for a mining permit include a Resource Utilization Plan Report, an Environmental Assessment Report, a Geological Hazards Assessment Report and a Soil Conservation Plan Report. The Company has received the notice of approval from the MLR for the start of the mining permit application on the project and compilation of the various reports are either underway or are to be commenced shortly.

Once all required reports are completed and positive reviews or approvals are received, the application for the mining permit will be filed with the MLR in Beijing. Based on the working guideline published by the MLR, it takes 45 business days for the MLR to make a decision after a completed application is submitted.

5 | ACCESSIBILITY, CLIMATE, RESOURCES, INFRASTRUCTURE AND PHYSIOGRAPHY

The GC Project is located around Gaocheng Village of Gaochun Township, Yun’an County, Guangdong Province, China. Altitudes in the region range from 78.0m to 378.0m above sea level (ASL), usually 150-250m ASL, with relative differences of 50-150m. Vegetation is in the form of secondary forests of pine and hardwoods, bushes and grasses. Top soil covers most of the ground. Outcrops of bedrocks can only be observed in valleys.

The GC Project is located west of the metropolitan city of Guangzhou, the capital of Guangdong Province. Guangzhou is located about 120 km northwest of Hong Kong and has a population of almost 12 million registered residents and temporary migrant inhabitants in December of 2007, according to an economic report released by the Guangzhou Academy of Social Science. It is serviced by rail and daily flights from many of China’s larger population centres. Access to the GC Project from Guangzhou is via 178 km of four lane express highway to Yunfu, then 48 km of paved road to the project site. A railway connection from Guangzhou to Yunfu is also available.

The region belongs to sub-tropical monsoon climate with average annual temperature of 20-22oC. Rainfall is mainly concentrated in spring and summer from March to August. Winters feature short periods of frosting. The GC Project would be able to operate year round.

Streams are well developed in the area, the Hashui River flows in the GC Project area. There is a reservoir upstream of the GC Project area. Small hydro power stations are developed in the region that are connected to the provincial electrical grid. There is a 10KV power line across through the project area.

The topography offers a number of opportunities for waste rock and tailings storage proximal to the resource to 5 km from the resource.

The economy of Yun’an County mainly relies upon agriculture and some small township industrial enterprises. Labour is locally available, and technical personnel are available in Yunfu and nearby cities. The Gaocheng village is located within the GC project area.

6.1 | History of Mining

Silvercorp informed AMC that prior to Yangtze Mining acquiring the GC Property, illegal mining activity resulted in the excavation of several tunnels and small scale mining of veins V2, V2-2, V3, V4, V5, V6 and V10.

The Guangdong Provincial Institute of Geological Survey (GIGS) reported a total of 1,398m of excavation comprised of 10 adits and tunnels had been completed on the property through the illegal activity. In 2002, GIGS developed 66m of tunnel to crosscut veins V5 and V5-1. GIGS sampled and mapped adits ML1 to ML5, ML6, ML7, ML9, and PD12.

Yangtze Mining, after their purchase of the property in 2005, mapped and sampled the accessible tunnels ML5 and ML8. Tunnel ML5 has exposure to vein V10 and tunnel ML8 has exposure to vein V2-2. Assay results of tunnel samples were used in resource estimation. Table 6.3 details the underground workings and work completed.

AMC visited the tunnel sites but was not able to access them as most entrances were blocked for safety reasons. There is no detailed reconciliation data available for any of the mineralization extracted.

6.2 | History of Mineral Resources

The Guangdong Provincial Institute of Geological Survey (GPIGS) prepared a resource estimate for nine mineralized veins for the GC Project after the 2004-2005 exploration season. The GPIGS has its own classification system of mineral resources/reserves which is different from CIM codes. AMC does not believe those resources are material to this report as they are non CIM – NI43-101 resource estimates and have been superseded by estimates that are.

Prior to this report a resource estimate for the GC Project was reported in a Technical Report by SRK dated April, 2008 and posted on SEDAR July 4, 2008. The Technical Report was entitled “Technical Report on Gaocheng Ag-Zn-Pb Project, and Shimentou Au-Ag-Zn-Pb Project, Guangdong Province, People’s Republic of China”. The SRK summary of the resource estimate at the GC Project for thirteen better-explored veins is listed as reported in Table 6.4.

7 | GEOLOGICAL SETTING

7.1 | Regional Geology

The factual information in this section has been primarily derived from the previous Technical Report on the property titled “Technical Report on Gaocheng Ag-Zn-Pb Project, and Shimentou Au-Ag-Zn-Pb Project, Guangdong Province, People’s Republic of China”, dated April, 2008.

The property is located at the north portion of the Yunkai uplift of the Southern China folding system, the east margin of the Luoding basin and east of the Wuchuan – Sihui major fault. Structurally, the deposit occurs at the intersection of a northeasterly striking fault zone and a near east-westerly striking fault zone. Northeast striking structures and arc structures form the basic geological framework of the region.

Figure 7.1 Tectonic Geology Map of Southern China

Regional outcrop includes Later Proterozoic Sinian sedimentary clastics and carbonate rocks, which host Ag-Pb-Zn multi-metallic deposits in the region, and Paleozoic Ordovician, Silurian, Devonian, Carboniferous sedimentary clastics and carbonate rocks which host some Cu-Pb-Zn, Mn and Au-Ag deposits, and Mesozoic Triassic coal-bearing clastics rocks, and Cretaceous red clastics rocks.

There are three sets of structures in the region. The north-easterly striking structure is comprised of a series of folds and faults that host some mineralized bodies. The near east-westerly striking structure dips steeply, and contains structural breccias within the faulting zones. Alteration zones are formed along both sides of the regional structures. Typically quartz is the filling in the faults. The third structure set is the arc or ring structures including folds and faults surrounding the Daganshan granite zone. The Pb-Zn-Ag-Sn deposits and mineralization showings, as well as geochemical anomalies of Au-Ag-Pb-Zn etc. occur in the arc or ring structural zone.

Magma intruded in the centre of the arc/ring structure. The intrusives include Paleozoic granite batholiths, and Mesozoic granite stocks and dykes. The Mesozoic stocks and dykes intruded in the inner zone of the arc/ring structure, and are associated with the Pb-Zn-Ag multi-metallic mineralization in the region.

The regional geochemical surveys defined multiple anomalies of Ag, Au, Pb, Zn etc. along the arc/ring structural zone. The GC deposit occurs in one of the anomalies.

Mineral deposits are abundant in the region. The Dajiangping Pyrite deposit, the Dajinshan W-Sn multimetallic deposit, the GC Pb-Zn-Ag deposit, the Jianshan-Shimentou Pb-Zn-Ag deposit, the Jiuquling Sn deposit, as well as many mineralization sites and showings, have been discovered in the region.

7.2.2 | Structures

The project area is situated in the southwest part of the Daganshan uplift. Structures developed in the area are mainly the NWW striking Gaocheng Fault zone, the NE striking Baimei Fault zone, and the Songgui Fault zone.

Figure 7.4 Two sets of joints (NE- and NWW-striking) were exposed in trench TC059

The NWW-striking fault zone is the main mineralization bearing structure in the deposit, and is also the most developed and the largest fault zone of the three. The Gaocheng Fault zone is part of the NWW structure. Most of the defined veins (V2-2, V2, V2-0, V2-1, V3, V4, V5, V5-1, V6, V6-0, V7, V7-0, V7-1, V8, V8-0, V8-1, V9, V9-0, V9-1, V13, V14, V15, and V15-1) are found in this fault zone. The fault zone is about 4.8km long and about 2000m wide with more than ten nearly parallel faults within a granite zone and the Cretaceous Luoding Formation. It strikes at 290°, dips SSW at angles of 60-80°, and is the main mineralization hosting structure in the area.

It is has been observed that the NE-striking faults cut through the NWW-striking structures with no or minor displacement. Mineralization veins such as V10, V10-1, V11 and V12 are controlled by the NE-extending fault zones.

The following two photos are of the NWW and NE striking faults. The faults demonstrate a sharp contact between the veins and the host rock.

NI 43-101 Technical Report Update on the GC Ag-Zn-Pb Project in
Guangdong Province, People’s Republic of China

9 | MINERALIZATION

The factual information in this section has been primarily derived from the previous Technical Report on the property titled, “Technical Report on Gaocheng Ag-Zn-Pb Project, and Shimentou Au-Ag-Zn-Pb Project, Guangdong Province, People’s Republic of China”, dated April, 2008. The tables and comments have been revised where warranted.

The 5.54 km2 GC Project area is crossed by mesothermal silver-lead-zinc quartz-pyrite veins in steeply-dipping fault-fissure zones which cut Mesozoic granite.

9.1 | Vein Structure

Structurally, the GC vein systems all appear to be generally similar, occupying steeply-dipping fault-breccia zones which trend most commonly northwest-southeast and less commonly northeast-southwest. The structures extend for hundreds to a few thousand meters along strike and are often filled by silicified structural breccias and cataclastic rocks of residual blasto-cataclastic texture and blastogranite texture, or are mapped as discrete zones of altered bedrock (mainly granite) with local selvages of quartz-pyrite veinlets.

The veins occur as steeply-dipping, tabular or splayed veins, commonly as sets of parallel and offset veins. Individual veins along the structures thin and thicken, from less than one meter up to tens of meters in width, in classic “pinch-and-swell” fashion. The pinching and swelling are the result of flexural irregularities from movement along the structure, with “swells” representing zones of dilation. The dilation zones (swells) are often sites of high-grade pockets or “ore shoots.”

9.2 | Mineralogy

The mineralized veins in the GC area occur in relatively permeable fault-breccia zones and are extensively oxidized from the surface to depths of about 40m. Within this zone, the veins show many open spaces with conspicuous boxwork lattice textures resulting from the leaching and oxidation of sulphide minerals. Secondary minerals present in varying amounts in this zone include kaolinite, hematite, and limonite.

The dominant sulphide is pyrite, typically comprising a few percent to 13% of the vein. Other constituents are a few percent of sphalerite, galena, pyrrhotite, arsenopyrite, magnetite and less than a percentage of chalcopyrite and cassiterite. Metallic minerals in much smaller amounts include argentite, native silver, bornite, wolframite, scheelite, and antimonite. The minerals occur in narrow massive bands, veinlets or as disseminations in the gangue. Gangue minerals include chlorite, quartz, fluorite, feldspar, mica, hornblende, etc., with a small amount or trace amount of kaolinite, tremolite, actinolite, chalcedony, garnet, zoisite, apatite and tourmaline, etc.

Pyrite, Pyrrhotite, Arsenopyrite. These are the main iron sulphide minerals and occur in both disseminated and veinlets forms.

Galena. Coarse grains of galena appear in subhedral-anhedral crystals. Galena occurs primarily embedded in, and in contact with, sphalerite and pyrite. It fills between grains of pyrite along with sphalerite and chalcopyrite. It may replace pyrite.

Sphalerite. Sphalerite mostly appears as xenomorphic granular shape, partially in subhedral granular shape. It commonly embeds into galena and pyrite, and fills between the grains of pyrite associated with galena and chalcopyrite, replacing slightly over pyrite.

Copper minerals. Copper-bearing minerals are mainly chalcopyrite, and a trace amount of bornite and tetrahedrite. Usually chalcopyrite appears in anhedral crystals, embedding and edging along sphalerite, galena, pyrite and arsenopyrite.

Silver minerals. Silver minerals are visible native silver and argentite, which mainly occur as embedded form in galena and anhedral pyrite, partially between the grains of pyrite, galena and sphalerite.

Cassiterite. Cassiterite mainly appears as disseminate anhedral grains, mostly between the grains of quartz, chlorite and hornblende, partially between the grains of galena and pyrite.

Mineralization Types. The Ag-Zn-Pb mineralization in the deposit can be divided into two types: primary and oxidized.

Primary mineralization. Is mainly composed of galena-sphalerite-silver ore minerals which occur sparsely, disseminate, and as veinlets and lumps. The type accounts for 95% of the entire mineral resource.

Oxidized mineralization. This occurs on and near the surface as a result of oxidization of the primary mineralization.

Alteration. Alteration minerals associated the GC vein systems include silica, sericite, pyrite and chlorite, together with clay minerals and limonite. Silicification is common near the center of the veins, chlorite and sericite occur near and slightly beyond the vein margins.

The mineralization is commonly associated with alteration distributed along the fault-breccia zone. A zonation of alterations is visible. From the centre out, the alterations change from pyritization, + fluoridization, to silicification + potassium felsparization + sericitization, to silicification + chloritization + kaolinization.

Silica, pyrite, fluorite, and chlorite are closely related to the mineralization.

9.3 | Characteristics of the Mineralized Veins

Based on surface mapping, trenching, tunnelling and drilling, the characteristics of 27 veins have been identified on the GC property are described as follows. V14, V15, and V15-1 were only encountered by single drill holes and veins V12 and V9-0 only contained very low-grade mineralization. As such they are not included in the descriptions below.

10 | EXPLORATION

Exploration work by Silvercorp on the GC property was carried out in 2008. The program is summarized in Table 10.1.

Table 10.1 Main Programs Conducted on the GC Property by Silvercorp

Program | Unit | Work Completed
2008
1:10,000 soil profiling | km | 10
Diamond drilling | m | 10,083
Trenching (pitting) | m3 | 740
Soil samples | sample | 535
Chemical analysis samples | sample | 2,139
Metallurgical testing | test | 1

The diamond drilling undertaken in 2008 represented 43% of all the diamond drilling on the property.

10.1 | Soil Geochemical Program

A 1:10,000 scale geochemical survey was done by taking samples from C-layer of top soils and the samples were assayed for Au, Ag, Cu, Pb, Zn, Mo, Sb, and As, etc. The program resulted in outlining significant Ag, Pb, and Zn anomalies, providing targets for surface trenching and pitting. Most of the veins on the property were discovered using the soil geochemical results.

In 2008, soil geochemical survey (1:10,000 scale) was carried out by Silvercorp through the collection of 535 samples within a 2.22 km2 area in the southern part of the property where no drilling had been previously performed. Three new Ag-Zn-Pb geochemical anomalies observed to be over 500m long and up to 250m wide were identified, providing priority drill targets with the potential to host additional veins.

10.2 | Topographic and Geological Mapping

GIGS conducted a 1:10,000, 1:5,000 and 1:2,000 geological mapping programs, and a 1: 2,000 topographic survey covering the GC Project area. The geological mapping programs established stratigraphic sequences, size, and distributions of intrusive rocks and faults.

The grid system used for the GC Project is Beijing Geodetic Coordinate System l954. Altitude is referred to Yellow Sea 1956 Elevation System. The project survey control points were generated from three nearby national survey control points. The control points were surveyed using four NGS-9600 GPS receivers. Survey machines used for topographical survey and geological points, trenches, adits, and drill hole collars were Topcon GTS-Serial Total Station Instrument – XJ0747 and one NX2350 and Sokkia SET-230PK Total Station Instrument.

10.3 | Trenching and Pitting

Based on the soil geochemical and surface mapping, Silvercorp conducted trenching and pitting programs on the GC property. The program exposed the mineralized veins on the surface and at shallow depth. A total of seven pits and one trench were dug by Silvercorp and exposed three veins. Table 10.2 contains the findings in detail.

11 | DRILLING

A total of 65 diamond drill holes have been completed on the GC property since 2001 totalling 23,546.34m. During 2008, Silvercorp completed 22 hole, 10,082.6m drilling program, which resulted in the discovery of an additional 15 mineralized veins. Drill hole locations are shown in Figure 11.1. The drill hole collar, downhole survey and core recoveries are listed in Appendix VI and VII.

Figure 11.1 Drill-hole locations in the GC property

Diamond drill holes were drilled using PQ size in overburden, then reduced to HQ size for up to 100m depth. The remainder of a hole was drilled using NQ size unless the hole was required to drill over 600m in length. Drill core recoveries vary from 85 to 100% and average 99%.

12 | SAMPLING METHOD AND APPROACH

The drill core is logged initially at the drill site and the mineralized or favourably altered intervals are moved to the surface core shack where they are logged, photographed and sampled in detail. Samples are taken prepared by cutting the core in half with a diamond saw. One half of the core is returned to the core box for archival storage, the other half is placed in a labelled cotton bag with the sample number written on the bag. The bagged core sample is then shipped to the laboratory for assaying.

Individual samples from the drill core are from veins that range in width from 0.05m to 12.03m. The veins consist of either massive sulphides or sulphide-bearing materials and can be easily identified and separately sampled from non-mineralized wall rock. Mineralized veins intercepted by drill cores were sampled in 1.5m maximum intervals and the distances cut where warranted by apparent wallrock.

Core recoveries are determined by measuring the actual amount of core recovered versus the length of the drilled interval from which the core was obtained. Core recoveries (calculated as percentage) are documented in the log. In general, the recoveries range from acceptable to excellent; although the recoveries vary somewhat from vein to vein.

Samples appear to have no apparent sampling or recovery difficulties that would affect the reliability of results. The samples appear to be representative and results of check samples show no apparent evidence of sample bias. Rocks sampled trenches, tunnels or in drill core are sulphide-rich veins that follow structures (faults). These veins are easily identified because of their bright metallic sulphides and they can be sampled with little difficulty.

The angle of the vein to core is determined by using the vein to core angles and cross-sectional correlations to determine the dip of the veins. The apparent thickness is then corrected to true thickness using simple trigonometry.

In AMC’s opinion, the sampling procedures and controls meet accepted industry standards. In general, the trench, chip and core samples appear to be representative of the areas examined and suitable for use in resource estimation.

13 | SAMPLE PREPARATION, ANALYSES, AND SECURITY

Drill core samples were taken from sawn half core for every 1.5m or limited by apparent wall rock and mineralization contact. Half of the core was sent to the laboratory for analysis and the other half retained for archive. The samples are individually secured in sample bags and then collectively secured in rice bags for shipment to the laboratory. Employees of Yangtze Mining, the subsidiary of Silvercorp, collect and split the core for sampling. No officer or director of either Silvercorp or Yangtze Mining has contact with any of these samples prior to shipment to the laboratory.

The samples are shipped directly in security sealed bags to ALS Chemex in Guangzhou, China (Certification ISO 9001:2000), located approximately 180 km southeast of the GC property site.

The sample preparation consists of drying, crushing and splitting of the sample with a riffle splitter to 150g then pulverizing the sample to 200 mesh. Ag, Pb and Zn in drill core samples were analyzed by aqua regia digestion and AAS. The prepared sample is digested in aqua regia (HNO3-HCl). After cooling, the resulting solution is diluted with de-ionized water, mixed and then analysed by inductively coupled plasma-atomic emission spectrometry (ICP-AES).

Detection ranges for this method are:

Element | Symbol | Units | Lower Limit | Upper Limit
Silver | Ag | g/t | 1 | 1500
Lead | Pb | % | 0.01 | 20
Zinc | Zn | % | 0.01 | 60

Soil samples were analysed by aqua regia digestion and ME-ICP.

Tin was analysed by fusing with peroxide, then leaching the melt and acidifying to precipitate out the tin for AAS finish.

Check samples including field duplicates and samples rejects are routinely sent to Laboratory of the Henan Institute of Geological Survey, located in Zhengzhou, Henan Province, Central China. In Henan Lab, lead, zinc, tin, and silver are all analysed with an Atomic Absorption Spectrometer after a three-hour hot aqua regia digestion on a 30 g split of the pulverized portion. A gravimetric finish is done on samples with silver values in excess of 1,500g/t. On samples containing more than 30% lead, an acid dissolution and titration is used to complete the analysis. Henan’s lower detection limits are 3 g/t for silver, 0.03% for lead and zinc.

Silvercorp’s check procedures include (a) inserting standards that were purchased by Langfang Lab and blanks that were prepared by Yangtze Mining in the every 40-sample batches submitted to the ALS Chemex lab on a regular basis, (b) submitting duplicate pulps to the ALS Chemex lab on a regular basis, (c) submitting 1/4 core samples as sample duplicates to the ALS Chemex for every 40-sample batches, and (d) submitting duplicate pulps to an independent external lab on an intermittent basis.

Details of these check procedures are offered in the previous Technical Report on the Ying Project (Broili, et.al., 2006). In general:

- Standards included in samples sent to Langfang have been within 3% for the lead, zinc and silver values.

- Duplicate pulps sent to the Langfang lab (restricted to samples containing more than 50 g/t Ag, 0.5% Pb and 0.5% Zn) show average differences of less than 1% for the silver and zinc values and 1.2% for the lead values.

- Duplicate pulps selected at random, rather than from regular intervals, and sent for check analyzes to ALS Chemex in Guangzhou, China, an ISO 9001:2000 accredited lab. The average differences between the Lanfang analyzes and the check analyzes are near or below 5% for silver, lead and zinc.

In AMC’s opinion, the procedures used by Silvercorp for the preparation, security, and analytical procedures appear to be adequate and conform to standard industry practices.

14 | DATA VERIFICATION

AMC Canada’s site visit was conducted by Brian O’Connor, P.Geo. from March 27 to March 30, 2009. During the site visit the following validation tasks were completed.

- Review of the state of geological and mineralization knowledge.

- Tour ALS Chemex facility in Guangzhou. Review of methodology and process flow.

- Visit surface expressions of mineralized veins V4 (ML3), V2 (BT-3), adit to V10 and site ML8 (V2-2).

- Review core logging and processing procedures, chain of custody for samples.

- Data set and compilation review.

- Review of the resource model block estimations.

- AMC could not verify the underground workings and sample data at the time of the site visit as the access to the underground workings was barricaded for safety reasons.

AMC requested 34 diamond drill samples from the 2008 drill campaign be quarter split. The quarter split samples were delivered to Eco Tech Laboratory in Kamloops, British Columbia, Canada for analysis. Eco Tech is a fully accredited to ISO 9001:2000 and is currently working toward 17025 accreditation. The results are listed in Table 14.1.

In general, the silver values returned from the quartered core analysis are in agreement with the original half core assay results. The lead and zinc values returned from the quarter core analysis are on average elevated with respect to the original half core assays. It is AMC’s opinion that there is not a systemic bias in the data for lead and zinc assays, but that the variations seen are a reflection of the distribution of the lead and zinc mineralization within the vein. AMC notes that the quartile analysis for lead is anomalously elevated only in the third quartile and zinc is elevated anomalously in the median (2nd) quartile and the maximum (4th) quartile. The other quartile results are within a +/- 5 to 10% error range.

AMC’s review of the QA/QC data did not reveal any major deficiencies that are likely to have a material impact on the assay results used in the resource database.

Silvercorp’s data is stored in digital format, for both internal and external audit purposes, hardcopy output of the raw and interpreted data in the form of tables, plans and sections was readily available.

AMC compared 40% of the original assay certificates with the assays used in the block grade estimates and noted only minor discrepancies. AMC’s check of 15% of the grade, area, volume and tonnage calculations did not reveal any major deficiencies that are likely to have a material impact on the resource estimates. AMC would recommend that Silvercorp undertake variography studies to refine the understanding of the grade distribution and utilize a kriging or inverse distance weighting approach to grade interpolation prior to future resource and reserve estimations.

AMC did note some discrepancies in the tabled assays on some sections where the lead and zinc assays were inverted. AMC investigated this finding and found that these typographic errors were not incorporated into the resource calculation.

AMC did not take samples from the trenches during the site visit. In AMC’s opinion the trench data influence is less than 2% of the Measured and Indicated Resource, thus not material to the viability of the project.

16 | MINERAL PROCESSING AND METALLURGICAL TESTING

Yangtze Mining retained Hunan Institute of Non-ferrous Metallurgical Studies (Hunan Institute) for a metallurgical test on the mineralization from the GC deposit. In March 2007, the Hunan Institute took three bulk samples from the stockpiles of mineralized material of local village miners, old tunnels and drilling cores. Table 16.1 summarizes the information about the samples. All of the samples were taken from mineralized vein V2.

Table 16.1 Summary of Gaocheng Samples Used for Metallurgical Testing

Sample No. | Weight (kg) | Ore Type | Pb (%) Zn (%) Ag (g/t)
GC1 | 120.0 | Massive | 4.68 6.01 96.56
GC2 | 147.5 | Disseminated | 1.86 4.28 61.20
GC3 | 393.5 | Mineralized rocks | 0.52 0.92 19.72

The samples were analysed for mineralogy and occurrences of the main beneficial elements, i.e., silver, lead, zinc, tin, and sulphur. The mixture of the samples at ratios of 1:1:2.9 for samples GC1:GC2:GC3 and grades of 40-60g/t Ag, 1.2-1.5% Pb and 2.3-2.5% Zn was used to conduct an ore processing experiment to produce a lead concentrate, a zinc concentrate, and a sulphur concentrate. Silver is mainly concentrated in the lead concentrate and the zinc concentrate. Below is a brief summary of the study.

16.1 | Mineralogy and Occurrences of the Beneficial Elements

The mineralogy of the composite samples is summarized below and given in Table 16.3. The percentages where presented have been rounded.

Occurrence of Silver. Silver grades in the samples range from 20g/t to 100g/t, averaging 46g/t. It is distributed in several minerals. It mainly occurs in silver sulphides, such as argentite, accounting for 35% of all silver, in other sulphides, such as pyrite, galena, and sphalerite etc., accounting for 25%, and in native silver, accounting for 20%, as well as in gangue minerals. Silver sulphide minerals occur closely with galena as inclusions within galena, or distributed in between galena grains. In general, the distribution of silver is 43% in galena, 25% in sphalerite, 21% in pyrite and other sulphides, and 12% in gangue minerals.

Occurrence of Zinc. Zinc grade in the samples range from 0.9 to 6.0%, averaging 2.4%. Zinc mainly occurs in sphalerite, accounting for 94% of total zinc, and secondarily in zinc carbonate minerals, 2%, zinc silicate minerals, 2%, and other minerals. Sphalerite usually occurs intergrown with galena and pyrite. Sometimes, it, together with galena and chalcopyrite, may occur in between the grains of pyrite. 94% of sphalerite crystals are greater than 0.037mm (-320mesh), with 12% greater than 1mm.

Occurrence of Lead. Lead grade in the samples range from 0.5 to 4.7%, averaging 1.4%. Lead mainly occurs in galena, accounting for 93% of total lead, and secondarily in lead carbonate minerals, 4%, and other minerals. Galena usually inter-grows with sphalerite and pyrite. Sometimes, it, together with sphalerite and chalcopyrite, may occur in between the grains of pyrite. 97% of galena crystals are greater than 0.037 mm (-320 mesh), with 15% greater than 1 mm.

Occurrence of Tin. Tin mainly occurs in cassiterite, accounting for 95% of total, and secondarily as colloid tin, 3%, and in other minerals.

Occurrence of Sulphur. Sulphur grades in the samples average about 10%. Sulphur mainly occurs in pyrite and pyrrhotite, accounting for 83.5% of total, and secondarily in sphalerite and galena, 14%, and other sulphide minerals. There are two types of iron sulphide minerals, one type occurs as subhedral crystals with grain sizes of 0.4-5 mm, and the other type occurs as fine grained (0.03-0.5 mm) anhedral crystals. Pyrite is relatively coarse with 97% greater than 0.037 mm (-320mesh), and 30% greater than 1mm.

16.2 Mineral Processing and Metallurgical Testing

Test Sample

In order to optimize a processing flowsheet for recovering lead, zinc, silver, tin and sulphur of the GC mineralization, Hunan Non-ferrous Metals Research Institute (HNMRI) was contracted to perform mineral process and metallurgical tests between February and April, 2009. Test sample was a composite of 158 drill core sample rejects from the 2008 drill program, which were originally collected for assaying. Grain size of the rejects was less than 2mm. Head grades are listed in Table 16.3.

Table 16.3 Head Grade of the Blended Test Sample

Cu (%) | Pb (%) | Zn (%) | S (%) | Sn (%) | Au(g/t) | Ag(g/t)
0.16 | 1.45 | 3.25 | 10.16 | 0.20 | 0.20 | 128.32

Average grades of composite sample are very close to the deposit grades.

Metallurgical Test

First Stage. After performing a number of tests at different conditions based on 2007 test results, optimized test parameters and processing techniques were finalized. Locked cycle tests were conducted. Lead and zinc flotations include one rougher, three cleaners, and two scavengers while pyrite (sulphur) was tested using one stage rougher, cleaner, and scavenger flotation. General locked cycle flowsheet and test results are shown in Figure 16.1 and Table 16.4.

16.3 | Bulk Density

A total of 62 samples were taken for bulk density measurement. The tests were done using the wax-immersion method by Guangdong Material Test Centre, a Chinese government certified lab located in Guangzhou, Guangdong, China. Samples ranged in size from 470 to 2,690g. Based on a cutoff grade of 100g/t AgEq (no recoveries included), the results of 56 samples were used to calculate the average bulk density for each vein on the GC property. The average bulk density is determined to be 3.57t/m3. Note that one extreme high grade sample, returning a value of 5.51 t/m3 and containing 2,793 g/t Ag, 53.04% Pb, 6.44% Zn was excluded from the overall bulk density calculation. Detailed bulk density sample data is listed in Appendix VI.

The average grades for these 56 samples are 176 g/t Ag, 1.99% Pb, and 4.47% Zn. In theory, bulk density is related positively to metal contents, especially lead and zinc. However, bulk density is sometimes high in low grade material if the pyrite content is high and it is noted that the GC deposit is rich in pyrite.

Bulk density values were assigned to three different grade groups as shown in Table 16.8.

17 | MINERAL RESOURCE AND RESERVE ESTIMATE

The mineral resource categories used in this report are those established by the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) in the CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines as adopted by the CIM Council dated December 2005. These resource definitions are summarized as follows:

| A Mineral Resource is a concentration or occurrence of diamonds, natural solid inorganic material, or natural solid fossilized organic material including base and precious metals, coal, and industrial minerals in or on the Earth’s crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge. |

A Measured Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, physical characteristics are so well established that they can be estimated with confidence sufficient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confirm both geological and grade continuity.

An Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.

An Inferred Mineral Resource is that part of a Mineral Resource, for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.”

Mineralization in the GC Project consists of narrow vein type deposits which occur as discrete planes of variable grade and variable thickness. The resources were outlined using polygonal methods on longitudinal sections constructed for each vein. The resource estimates reported herein were prepared using such methods by Mr. Wang Qiang, Chief Geologist of Yangtze, and Mr. Myles J. Gao, P.Geo, President of Silvercorp, who is a Qualified Person, as defined by NI 43-101. AMC has reviewed Silvercorp’s methodologies and data used to prepare the resource estimates and is satisfied that they comply with reasonable industry practice, subject to a qualification with respect to use of the polygonal method. Although this is a common estimation method in China and its use by Silvercorp therefore accords with common industry practice in that country, the technique tends to produce estimates that are higher in grade and lower in tonnage than methods in common use in Canada, such as kriging or inverse distance weighting.

Following is an explanation with comments regarding the parameters and assumptions used to prepare the resource estimations reported in this Technical Report:

| A polygonal block model was used in this resource estimation.
| The polygonal block model utilizes detailed long-sections constructed for each of the veins. The topographic control for these sections is taken from 1:2,000 topographic map.
| Polygonal resource blocks drawn on long-sections of the vein were constructed, and their areas measured, using MapGIS, a MapInfo-like GIS software application widely used in China.
| Sulphide resources are estimated using only the assays obtained from drilling and historical tunnelling. A small portion of samples (41 assays) from 17 surface trenches were used for the oxide block resource estimates. Channel samples from tunnels were taken by GIGS from 2003 to 2005. Yangtze Mining performed a check by re-sampling the channels and found the GIGS results were reliable.
| The minimum cut-off thickness used for mineralization is 0.20m.
| The veins are polymetallic containing several payable metals. Although contents of each of the payable metals are separately reported in the resource estimations, Silvercorp uses an “equivalent-silver” value to assess and compare the vein resources. The “equivalent-silver” value, which are reported in the resource estimate tables, are calculated as follows:

| AgEq(g) = ((Ag g/t * $Ag/g * Ag Recovery) / $Ag/g)
| + ((Pb% * $Pb/lb * Pb Recovery * 22.0462) / $Ag/g)
| + ((Zn% * $Zn/lb * Zn Recovery * 22.0462) / $Ag/g)

| No dilution has been applied with the exception of the 11 individual Resource block occurrences below 0.20m in horizontal width in the dataset used for the resource estimate. Those 11 occurrences were diluted at zero grade to 0.20m in horizontal width.
| Any interpolations are based upon vein thickness and grade.
| The wall rock surrounding the veins is in sharp contact with the veins and commonly silicified.
| The data and methods employed are adequate to allow resources to be categorized as Measured, Indicated and Inferred.
| Resource blocks categorized as “Measured” are defined by assays from tunnel samples on vein and drill holes samples. These blocks are projected up to 25m above and below a given tunnel where warranted, and along strike from a given tunnel intersection or projected from a drill hole intercept within 50m of a tunnel sample.
| Resource blocks categorized as “Indicated” begin either above or below a Measured Resource block or are projected from a drill intercept. For blocks projected from the Measured resource blocks, the distances are not greater than 50m. For blocks projected from drill holes, the distances are not greater than 50 to 60m. Block boundaries are defined as the midpoint between drill holes.
| Resource blocks categorized as “Inferred” use grades and thicknesses derived from the average of all the Measured and Indicated blocks along the vein. For veins intersected by deep holes, the Inferred Resource blocks are projected 100m down-dip from the Indicated blocks.

17.1 | Resource Data and Statistics

The information used to estimate project resources is maintained in a series of linked Excel worksheets maintained for all exploration areas. The worksheets contain individual sample information such as sampling dates, locations, sample number, elevation, width, and assay results, and additionally, for drill holes, collar information, down hole survey data, sample intervals, and assay results. The data are organized in a manner such that information plotted on the vein long-sections and used to constrain boundaries of the resource block polygons can be readily retrieved and verified, samples on a vein-by-vein basis, and within each vein on a pocket-by-pocket basis, such that widths, grades and tonnages can be calculated if warranted down to very small blocks or areas within each vein.

There are 5,280 samples in the database. 740 of these samples are used to define 26 veins in which 492 samples are used for resource estimates (Table 17.2).

17.2 | Resource Estimates

The Ag-Zn-Pb metals are reported separately in the resource estimates. A range of recovered cut-off values is presented in Table 17.5 to demonstrate sensitivity. AMC is not aware of any environmental, permitting, legal, title, taxation, socio-economic, marketing or political issues that would materially affect the mineral resource estimate in Table 17.6. The GC Project contains two additional commodities that have not been incorporated into the silver equivalent calculation. The first is sulphur which would take the form after processing of a sulphur concentrate containing silver. The silver in the sulphur concentrate has been accounted for in the silver equivalent equation. The second commodity that has not been accounted for in the silver equivalent equation is tin. Silvercorp is researching the potential to produce tin as a saleable product but at the time of the production of the resource estimate the issue remained undetermined.

Mineral resources that are not mineral reserves do not have demonstrated economic viability.

300g/t Recovered AgEq Cut-off | 2,970,000 | 197 | 1.97 | 4.08 | 393

The estimated mineral resources for the 26 veins of the GC project are summarized in the following table using the 150g/t recovered AgEq cut-off. The result of the update was an increase of 250% in the sum of the Measured and Indicated Resources for the project. Note the subtotals have been rounded and may not sum to the totals due to the rounding.

18 | OTHER RELEVANT DATA AND INFORMATION

Sulphur and tin are potentially economic commodities that have not been fully explored in this report.

18.1 | Mining Method

Two mining methods which have been applied at the company’s Ying, TLP and LM mines to extract very narrow vein mineralization are described in the Silvercorp 2009 Annual Information Form and presented below. AMC understands that these methods are being considered for the GC Project with the potential to mechanize parts of the mining methods.

1) Short-Hole Shrinkage Stoping:

This has been employed worldwide as a successful mining method for narrow veins. The system begins with undercut drifting exposing the vein in the back of the drift. A bypass drift is then driven from where crosscuts at approximately 8m spacing are driven. The crosscuts which intersect the vein act as draw points for the loading out of ore. Two raises are driven at each end of the stoping block.

The typical size of a stope is 50m along strike of the vein and approximately 40m in height. Two access raises approximately 1.8m by 1.8m are driven providing access to the stope and services air, water and ventilation. The average width of all veins in the TLP mine is 1.57m and 0.8m is the minimal width that can be mined using short-hole shrinkage with very little dilution. Veins which are less than 0.8m must be diluted to 0.8m with the assumption that the waste contains no grade. It is expected that 80- 85% mining recovery of in situ resources is possible.

The mining crew normally consists of two Jack Leg miners. A 1.8m round is blasted filling the void below as the mining proceeds upwards. While the crew is mining upwards only approximately 30% of the ore may be extracted from the stope until the entire stope is mined at which point all ore may be extracted. During the initial phase of mining, expected production is 50-75 tons per day per stope. The mine plan is a combination of completed and developing stopes. The crew drills and charges the holes with cartridge explosives and ignite the blast with tape fuse. A second crew will return to the stope after the smoke has cleared from the previous round. Ventilation air and water are carried up the raises to the stopping level. Loading of the ore from the draw points is by hand to diesel tricycle carts or hand carts.

2) Re-suing

The re-suing methods involve first blasting narrow ore veins between 0.l and 0.40m in width. After the ore is blasted and loaded from steel mill holes which are constructed as the stope is mined upwards, the waste on the footwall and hanging wall is blasted to maintain a minimum mining width of 0.8m. The stope will contain no ore when mining is complete in contrast to the method above. The stope is left filled with waste from the slashing of the footwall and hanging wall waste necessary to maintain a minimum mining thickness. For the re-suing method, the dilution factor is 15% and mining recovery is 90%.

19 | INTERPRETATION AND CONCLUSIONS

Silvercorp has a good understanding of the geology and mineralized trends on the property. AMC notes that the veins outlined to date have not been closed off by drilling and it is anticipated that ongoing exploration will continue to increase the overall resource and upgrade the classification of known resources.

A metallurgical test program was completed in May 2009 on the GC Project mineralization. The test work indicates, on a rounded percentage basis, an 85%, 88% and 85% recovery in concentrate for Ag, Pb and Zn respectively.

Mineral Resources estimates were prepared by Silvercorp and reviewed and classified by AMC following CIM best practices. Using a 150g/t (recoveries included) AgEq cut-off Measured and Indicated Resources are estimated to total 6,408,000 tonnes grading 138g/t Ag, 1.49% Pb and 3.34% Zn. Inferred Mineral Resources are estimated to total 7,892,000 tonnes grading 121g/t Ag, 1.45% Pb and 2.70% Zn.

As of May 2009, Silvercorp has made the following progress in applying for a mining permit and advancing the project towards production:

|  | An Environmental Assessment Report was completed in March 2009 and passed a review by an expert panel appointed by the Environmental Production Bureau of Guangdong. Pending receipt of the final approval, a mining permit application can be submitted to the Ministry of Land and Resources of China in Beijing.
|  | Silvercorp has engaged a Chinese engineering firm with Class A qualifications in mine and mill design to provide a full mine and mill design for the project.

Silvercorp’s mining experience includes majority ownership of four mines in the Ying Mining District of Hunan Province in central China held in two Sino-Foreign Cooperative Joint Venture companies. In addition, Silvercorp owns and operates two flotation mills in the Ying Mining District.

20 | RECOMMENDATIONS

Given the success of Silvercorp’s 2008 (fiscal 2009) exploration program, The Company’s primary focus in 2009 (fiscal 2010) at the GC Project is the mining permit application. The long-term goal is to put the GC Project into production.

The company has budgeted approximately $4 million for the GC Project in 2009 (fiscal 2010) for exploration, mine and mill designs, permitting, associated reports and reporting. The exploration program will be composed of approximately 3,000m of diamond drilling. A Chinese firm has been engaged for the mine and mill design.

AMC has reviewed Silvercorp’s exploration and development plans and budget and is of the opinion that they are well conceived and appropriate to the stage of the project. AMC recommends Silvercorp conduct the program as proposed subject to funding and any other findings or events during the exploration and design phase.

AMC makes the following recommendations with respect to resource estimation:

| 1) | AMC would recommend that Silvercorp undertake variography studies to refine the understanding of the grade distribution and utilize a kriging or inverse distance weighting approach to grade interpolation prior to future resource and reserve estimations.
| 2) | Continue the wax immersion bulk density measurements and continue to analyse the data on a vein by vein basis. AMC would suggest a sulphur or sulphide analysis as a basis for the bulk density assumptions.

| 3) | Carry out further studies into the potentially economic Sn and S components of the milling process.
| 4) | Carry out further metallurgical and mining studies into the oxidized zone prior to a future resource and reserve estimation.
| 5) | Consider the use of either electro-magnetic or induced polarization/resistivity surveys to help predict the orientation and extent of the structures bearing pyrite and/or galena.
| 6) | AMC recommends that the underground workings be reopened once the mining permit has been granted and that consideration be given to collecting a bulk sample and undertaking a test mining program.

Silvercorp randomly selected 130 sample pulps from a total of 2,139 samples collected for 2008 drill program for external checks. Check analyzes were performed by Laboratory of the Henan Institute of Geological Survey in Zhengzhou, Henan Province. These external checks were selected based upon different cutoffs of silver equivalent grade of original assay results.

Table III.1 Number of checks selected for each silver equivalent cutoffs

Ag Equivalent (g/t) | Totals Samples | Checks Selected | Checks out of total samples
>=50 | 199 | 76 | 38%
<50 | 1,940 | 54 | 3%
Total | 2,139 | 130 | 6%

Analytical check result comparisons with the original analyzes are listed in Table IV-2. As shown in Table V-2 and V-3 and on scatter plots, for assays close to detect limits and magnitude of absolute differences between originals and checks are small.

In order to test the accuracy, precision, and lab contamination, Silvercorp purchased two types of standards GBW07173 and GBW07163 (GSO-2). For core samples from four holes that were first drilled in 2008, the standards were inserted for every 20 samples, and then were inserted for every 40 samples for the rest of drill core samples. A total of 20 standards were inserted for assaying and the summarized assay results are listed in Table IV.1. Overall the standard sample results were assayed were within the variation ranges; one standard sample was above the allowed range for Zn and another sample was above the allowed range for Ag.

Table IV.1 Summary of Assay Results of Silvercorp’s Standards

Standard | Metals | Value of Standard | Assay Value
Average Value | Range | Average Value | Range | SD (σ)
GBW07173 | Ag (g/t | 92 | 92 ± 11 | 97.5 | 94-100 | 1.9
Pb (% | 2.14 | 1.97-2.17 | 2.09 | 2.04-2.16 | 0.04
Zn (% | 6.06 | 6.06 ± 0.29 | 6.24 | 5.99-6.48 | 0.15
GBW07163(GSO-2) | Ag (g/t | 220 | 220 ± 10 | 231.5 | 226-236 | 3.31
Pb (% | 2.17 | 2.17 ± 0.07 | 2.13 | 2.09-2.20 | 0.04
Zn (% | 4.26 | 4.26 ± 0.15 | 4.36 | 4.19-4.45 | 0.09

Silvercorp also utilized 1/4 core samples to compare assay results with 1/2 core samples on the same interval of a drill hole. Thirty quarter-core samples were collected and assayed. Eighteen of 30 samples containing above 50 g/t Ag equivalent are used to perform analysis and are shown in Table IV.2 and Figures IV.1 to IV.3. The comparison shows that the average difference between half core and quarter core assays at +/-10%, indicate the ALS Chemex assay results are generally reliable. However, 9 Ag, 11 Pb, and 10 Zn assays have over 10% difference between half and quarter samples and usually 1/2 core sample assays are higher than 1/4 core.
