ITEM 1.	GENERAL

1.1	Date of Information

All information in this Annual Information Form ('AIF') is as of March 31, 2021, unless otherwise indicated.

1.2	Forward Looking Statements

Certain statements and information in this AIF for Silvercorp Metals Inc. ('Silvercorp' or the 'Company') constitute 'forward-looking statements' within the meaning of the United States Private Securities Litigation Reform Act of 1995 and 'forward-looking information' within the meaning of applicable Canadian provincial securities laws. All statements and information concerning mineral resource and mineral reserve estimates may also be deemed to constitute 'forward-looking statements' to the extent that they involve estimates of the mineralization that will be encountered if the property is developed. Any statements or information that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as 'expects', 'is expected', 'anticipates', 'believes', 'plans', 'projects', 'estimates', 'assumes', 'intends', 'strategies', 'targets', 'goals', 'forecasts', 'objectives', 'budgets', 'schedules', 'potential' or variations thereof or stating that certain actions, events or results 'may', 'could', 'would', 'might' or 'will' be taken, occur or be achieved, or the negative of any of these terms and similar expressions) are not statements of historical fact and may be forward-looking statements or information. Forward-looking statements or information relate to, among other things: the price of silver, lead, zinc and other metals; the accuracy of mineral resource and mineral reserve estimates at the Company's material properties; estimated production from the Company's mines in the Ying Mining District (defined herein) and from the GC Mine; availability of funds from production to finance the Company's operations; access to and availability of funding for future construction and development of the Company's properties or for acquisitions; and other forecasts and predictions with respect to the Company and its properties.

Forward-looking statements are based on the opinions, assumptions, factors and estimates of management considered reasonable at the date the statements are made. The opinions, assumptions, factors and estimates which may prove to be incorrect, include, but are not limited to: the specific assumptions set forth in this AIF, or incorporated by reference herein; the expectations and beliefs of management; that prices for minerals, particularly silver, gold, lead and zinc remain consistent with the Company's expectations; that there are no significant disruptions affecting operations, including labour disruptions, supply disruptions, power disruptions, security disruptions, damage to or loss of equipment, whether due to flooding, political changes, title issues, intervention by local communities, environmental concerns, pandemics (including COVID-19) or otherwise; that operations, development and exploration at the Company's projects proceed on a basis consistent with expectations and the Company does not change its development and exploration plans and forecasts; that prices for key mining supplies, including labour costs and consumables remain consistent with the Company's current expectations; that plant, equipment and processes will operate as anticipated; that there are no material variations in the current tax and regulatory environment or the tax positions taken by the Company; that the Company will maintain access to surface rights; that the Company will be able to obtain and maintain government approvals, permits and licenses in connection with its current and planned operations, development and exploration activities; that the Company is able to meet current and future obligations; and that the Company can access adequate financing, appropriate equipment and sufficient labour, all at acceptable rates.

mineralization and metal recovery; interpretations and assumptions of mineral resource and mineral reserve estimates; exploration and development programs; economic factors affecting the Company; timing, estimated amount, capital and operating expenditures and economic returns of future production; integration of future acquisitions into existing operations; permits and licences for mining and exploration in China; title to properties; non-controlling interest shareholders; acquisition of commercially mineable mineral rights; financing; competition; operations and political conditions; regulatory environment in China; regulatory environment in Mexico; environmental risks; dependence on management and key personnel; foreign exchange rate fluctuations; insurance; risks and hazards of mining operations; conflicts of interest; internal control over financial reporting as per the requirements of the Sarbanes-Oxley Act; outcome of current or future litigation or regulatory actions; bringing actions and enforcing judgments under U.S. securities laws; cyber-security risks; the Company's investment in New Pacific Metals Corp; and the Company's investment in Whitehorse Gold Corp.

This list of risk factors described in this AIF the Company's other disclosure documents are not exhaustive of the factors that may affect any of the Company's forward-looking statements or information. Forward-looking statements or information are statements about the future and are inherently uncertain, and actual achievements of the Company or other future events or conditions may differ materially from those reflected in the forward-looking statements or information due to a variety of risks, uncertainties and other factors, including, without limitation, those referred to in this AIF under the heading 'Risk Factors' and elsewhere. Although the Company has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated, described or intended. Accordingly, readers should not place undue reliance on forward-looking statements or information.

The Company's forward-looking statements and information are based on the assumptions, beliefs, expectations and opinions of management as of the date of this AIF, and other than as required by applicable securities laws, the Company does not assume any obligation to update forward-looking statements and information if circumstances or management's assumptions, beliefs, expectations or opinions should change, or changes in any other events affecting such statements or information. For the reasons set forth above, investors should not place undue reliance on forward-looking statements and information.

1.3	Cautionary Note to U.S. Investors Concerning Preparation of Mineral Resource and Mineral Reserve Estimates

This AIF has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of the United States Securities and Exchange Commission's (the 'SEC'). The terms 'mineral resources', 'measured mineral resources', 'indicated mineral resources' and 'inferred mineral resources' used in this AIF are in reference to the mining terms defined in the Canadian Institute of Mining, Metallurgy and Petroleum Standards (the 'CIM Standards'), which definitions have been adopted by National Instrument 43-101 Standards of Disclosure for Mineral Projects ('NI 43-101'). Accordingly, information contained in this AIF providing descriptions of the Company's mineral deposits in accordance with NI 43-101 may not be comparable to similar information made public by other public companies subject to the technical disclosure requirements of the SEC.

Readers are cautioned not to assume that all or any part of mineral resources will ever be converted into reserves. Pursuant to CIM Standards, 'inferred mineral resources' are that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Such geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An inferred mineral resource has a lower level of confidence than that applying to an indicated mineral resource and must not be converted to a mineral reserve. However, it is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource is economically or legally mineable.

4

Canadian standards, including the CIM Standards and NI 43-101, differ significantly from standards in the SEC's Industry Guide 7 ('Guide 7') under the United States Securities Act of 1933, as amended. Effective February 25, 2019, the SEC adopted new mining disclosure rules under subpart 1300 of Regulation S-K of the United States Securities Act of 1933, as amended (the 'SEC Modernization Rules'), with compliance required for the first fiscal year beginning on or after January 1, 2021. The SEC Modernization Rules replace the historical property disclosure requirements included in Guide 7. As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of 'measured mineral resources', 'indicated mineral resources' and 'inferred mineral resources'. In addition, the SEC has amended its definitions of 'proven mineral reserves' and 'probable mineral reserves' to be substantially similar to corresponding definitions under the CIM Standards. During the period leading up to the compliance date of the SEC Modernization Rules, information regarding mineral resources or reserves contained or referenced in this AIF may not be comparable to similar information made public by companies that report according to U.S. standards. While the SEC Modernization Rules are purported to be 'substantially similar' to the CIM Standards, readers are cautioned that there are differences between the SEC Modernization Rules and the CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as 'proven mineral reserves', 'probable mineral reserves', 'measured mineral resources', 'indicated mineral resources' and 'inferred mineral resources' under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules.

For the year ended March 31, 2021 ('Fiscal 2021'), on a consolidated basis, the Company mined 964,925 tonnes of ore, an increase of 9% or 79,095 tonnes of ore, compared to 885,830 tonnes in the year ended March 31, 2020. For Fiscal 2021, the Company had revenue of $192.1 million up 21% compared to $158.8 million in the prior year, and cash flow from operations of $85.9 million up 11% or $8.7 million compared to $77.2 million in the prior year. For Fiscal 2021, net income attributable to equity holders of the Company was $46.4 million, or $0.27 per share.

On July 20, 2020, Silvercorp reported its first underground drill hole at the DCG Mine at the Ying Mining District. In 2006, Silvercorp acquired the DCG exploration permit, which is adjacent to the north of the TLP Mine. It covers an area of 19.77 km². A series of drill programs between 2006 and 2011 of 25 drill holes comprised of 9,026 m focused on obvious lead-zinc veins. A maiden resource estimate that complies with Chinese government requirements, but not NI 43-101, was completed in 2014, and Silvercorp successfully converted the exploration permit to a mining permit in 2015. Information regarding the DCG Mine, including a resource estimate, is contained in the 2020 NI 43-101 technical report for the Ying Mining District prepared by AMC Mining Consultants (Canada) Ltd. ('AMC'). In late 2018, the Company decided to develop the DCG Mine and bring it into production.

On August 31, 2020, Silvercorp reported the results of an updated NI 43-101 technical report on the Ying Mining District with an effective date of July 31, 2020 prepared by AMC. The Company reported an 18% increase in measured and indicated silver resources and 4% increase in proven and probable silver reserves, on top of 21 million ounces of silver produced between June 2016 and December 2019 at the Ying Mining District.

On November 30, 2020, Silvercorp filed a final short form base shelf prospectus with the securities regulators in each province of Canada, except for the Province of Quebec, and a corresponding shelf registration statement on Form F-10 with the SEC. The prospectus and registration statement allows the Company to offer up to US$200 million of Common Shares, preferred shares, debt securities, warrants, subscription receipts or any combination thereof ('Securities') during the 25 month period that the shelf prospectus is effective. The specific terms of any offering of Securities, including the use of proceeds from any offering, will be set forth in a shelf prospectus supplement. Silvercorp filed the shelf prospectus and corresponding registration statement in order to provide the Company with greater financial flexibility going forward. A copy of the final short form base shelf prospectus can be found on SEDAR at www.sedar.com and a copy of the registration statement can be found on EDGAR at www.sec.gov.

On December 16, 2020, Silvercorp announced the publication of its inaugural sustainability report, prepared in accordance with the Global Reporting Initiative (GRI) Standards: Core Option. The report provides information on the Company's governance, safety, environmental, and social performance.

On April 28, 2021, Silvercorp announced the receipt of three exploration permits of 48.8 km² in area, covering depth extensions of three mining permits, SGX, HPG, and TLP-LME-LMW, at the Ying Mining District.

La Yesca Project

In December 2020, the Company and its subsidiary, New Infini, entered into a framework agreement with various arm's length vendors (the 'Vendors'), whereby New Infini agreed to acquire a 100% interest in the La Yesca Project through the indirect purchase of all of the issued and outstanding shares of Infini Resources, S.A. de C.V., a Mexican company which owns the La Yesca Project. The La Yesca Project is a silver-polymetallic, epithermal-type project located approximately 100 km (185 m by road) northwest of Guadalajara, the second-largest city in Mexico. The concessions comprising the La Yesca Project cover an area of approximately 47.7 km². In total, 7,649 m from 25 drill holes have previously been completed, all of which intersected mineralization.

In January 2021, New Infini completed a private placement and raised $4.0 million by issuing 8,000,000 shares of New Infini at $0.50 per share. The Company purchased an additional 3,000,000 shares for $1.5 million. As at March 31, 2021, New Infini had a total of 48,000,000 shares issued and outstanding, of which the Company owned 21,000,000 shares or 43.75%, the Vendors owned 18,600,000 shares or 38.75%, and the management and investors owned 8,400,000 shares or 17.5%.

Based on New Infini's share structure, board composition and other related facts, the Company concluded that the Company has control over New Infini and accordingly, consolidates New Infini's results from the date of the acquisition.

Zhonghe Silver Project

On December 17, 2020, the Company, through its subsidiary, Henan Found, won an online auction to acquire the exploration rights to the Zhonghe Silver Project (the 'Zhonghe Project') from the Henan provincial government.

The Zhonghe Project covers an area of 4.96 km², approximately 50 km (75 km by road) northeast of the Company's Ying Mining District, also located in Luoning County. The final winning bid submitted by the Company was approximately $76.0 million (RMB¥495.0 million) (the 'Purchase Price').

Based on the current regulations, 20% of the Purchase Price, approximately $15.2 million, is required to be paid upon the execution of a formal mineral rights transfer contract (the 'Transfer Contract') with the Department of Natural Resources of Henan Province. The balance of the Purchase Price is due only if the exploration rights to the Zhonghe Project are converted into a mining license and shall be paid annually over the duration of the term of the mining license.

The execution of the Transfer Contract is pending the national security clearance by the relevant Chinese authorities.

Whitehorse Gold

Whitehorse Gold Corp. ('Whitehorse Gold') is a Canadian public company listed on the TSX Venture Exchange (the 'TSX-V') under the symbol 'WHG'.

On July 22, 2020, New Pacific Metals Corp. ('New Pacific Metals') announced the spin-out by way of a plan of arrangement (the 'Arrangement') of its then wholly owned subsidiary, Whitehorse Gold, which owns 100% owned of the Skukum Gold Project (formerly 'Tagish Lake Gold Project') located in Yukon, Canada. Upon completion of the Arrangement on November 18, 2020, New Pacific Metals and Whitehorse Gold became two separate entities, and New Pacific Metals distributed all of the Whitehorse Gold common shares to its shareholders, including to Silvercorp, on a pro rata basis. As a result, on November 18, 2020,

10

Silvercorp received a total of 5,740,285 Whitehorse Gold shares distributed under the Arrangement. In connection with the Arrangement, Whitehorse Gold conducted a non-brokered private placement financing, pursuant to which the Company acquired an additional 5,774,000 Whitehorse Gold common shares. As at March 31, 2021, the Company owned 11,514,285 common shares of Whitehorse Gold, representing 26.99% of the issued and outstanding Whitehorse Gold shares.

On May 14, 2021, Whitehorse Gold closed concurrent private placement offerings for aggregate gross proceeds of CAD$15,264,590. The Company participated in the offering and acquired an additional 4,000,000 units, each unit consisting of one common share in the capital of Whitehorse Gold and one common share purchase warrant. Following closing, Silvercorp owned an aggregate of 15,514,286 Whitehorse Gold common shares, representing 29.50% of the issued and outstanding shares of Whitehorse Gold on a non-diluted basis. Assuming conversion of 4,000,000 warrants, Silvercorp would own 19,514,286 Whitehorse Gold common shares, representing a 34.48% of the issued and outstanding Whitehorse Gold shares on a partially-diluted basis.

Guyana Goldfields

On April 26, 2020, the Company entered into a definitive agreement with Guyana Goldfields Inc. ('Guyana Goldfields'), subsequently amended on May 16, 2020 (collectively, the 'Arrangement Agreement') to acquire all of the issued and outstanding shares of Guyana Goldfields.

The total milling cost and cash milling cost1 at the Ying Mining District in Fiscal 2021 were $11.52 and $9.69 per tonne, down 4% and 5%, respectively, compared to $12.03 and $10.16 per tonne in Fiscal 2020. Correspondingly, the cash production cost¹ per tonne of ore processed in Fiscal 2021 at the Ying Mining District was $83.01, up 8% compared to $77.08 in the prior year.

The cash cost¹ per ounce of silver, net of by-product credits, at the Ying Mining District in Fiscal 2021, was negative $0.39, compared to negative $1.18 in the prior year. The all-in sustaining cost¹ per ounce of silver, net of by-product credits, at the Ying Mining District in Fiscal 2021, was $6.09 compared to $5.49 in the prior year. The increase was mainly due to the increase of per tonne cash production, offset by an increase of $0.16 in by-product per ounce of silver. Revenue from lead and zinc was $48.7 million, up $0.5 million, compared to $48.2 million in Fiscal 2020.

GC Mine

In Fiscal 2021, the total ore mined at the GC Mine was 314,900 tonnes, up 9%, compared to 287,633 tonnes in Fiscal 2020, while ore milled increased by 9% to 316,179 tonnes from 290,610 tonnes in the prior year.

1 Non-IFRS measure. Please refer to the reconciliation in section 12 of the MD&A for the corresponding period.

12

Average head grades were 85 g/t for silver, 1.7% for lead, and 3.4% for zinc in Fiscal 2021, compared to 97 g/t for silver, 1.9% for lead, and 3.3% for zinc in the prior year.

In Fiscal 2021, the GC Mine sold 705 thousand ounces of silver, 10.4 million pounds of lead, and 20.9 million pounds of zinc, compared to 699 thousand ounces of silver, 10.9 million pounds of lead, and 18.1 million pounds of zinc in Fiscal 2020.

The total mining and cash mining cost¹ at the GC Mine in Fiscal 2021 were $47.68 and $38.56 per tonne, respectively, a slight increase of 3% and 1%, respectively, compared to $46.40 and $38.06 per tonne in Fiscal 2020. The total milling and cash milling cost¹ at the GC Mine in Fiscal 2021 were $14.25 and $12.88 per tonne, down 8% and 7%, respectively, compared to $15.52 and $13.85 per tonne in Fiscal 2020. Correspondingly, the cash production cost¹ per tonne of ore processed at the GC Mine in Fiscal 2021 decreased slightly to $51.44 from $51.91 in the prior year.

The cash cost¹ per ounce of silver, net of by-product credits, at the GC Mine in Fiscal 2021, was negative $11.48, compared to negative $7.65 in the prior year. The all-in sustaining cost¹ per ounce of silver, net of by-product credits, at the GC Mine in Fiscal 2021, was $nil compared to $0.77 in the prior year. The improvement was mainly due to an increase of $5.47 in by-product credits per ounce of silver, offset by an increase of 7% in all-in sustaining production cost per tonne of ore processed.

BYP Mine

The BYP Mine was placed on care and maintenance in August 2014 due to the required capital upgrades to sustain ongoing production and the market environment. In Fiscal 2021, the Company sold all remaining gold concentrate inventories, containing approximately 1,200 ounces of gold, that had been produced by the mine before it was placed on care and maintenance.

The Company is carrying out activities to apply for a new mining license, but the process has taken longer than expected. No guarantee can be given that the new mining licenses for the BYP Mine will be issued, or if they are issued, that they will be issued under reasonable operational and/or financial terms, or in a timely manner, or that the Company will be in a position to comply with all conditions that are imposed.

Capitalized Exploration and Development Expenditures

Ying Mining District

In Fiscal 2021, a total of 208,904 m or $6.9 million worth of diamond drilling were completed at the Ying Mining District (Fiscal 2020 - 85,643 m or $2.5 million), of which a total of 150,324 m or $3.2 million worth of underground diamond drilling were expensed as part of mining costs (Fiscal 2020 - 85,643 m or $2.5 million) and a total of 58,580 m or $3.7 million worth of surface drilling were capitalized (Fiscal 2020 - nil). In addition, approximately 22,918 m or $6.7 million worth of preparation tunnelling were completed and expensed as mining preparation costs (Fiscal 2020 - 19,088 m or $5.7 million) at the Ying Mining District, and approximately 73,350 m or $27.4 million worth of horizontal tunnels, raises and declines were completed and capitalized (Fiscal 2020 - 70,240 m or $23.9 million).

ITEM 4	DESCRIPTION OF THE BUSINESS

4.1	General

Silvercorp's principal products and its sources of sales are silver-bearing lead and zinc concentrates. At present, Silvercorp sells all its products to local smelters or companies in the mineral products trading business.

For each of the Company's two most recently completed fiscal years, revenues for each category of products that accounted for 10% or more of total consolidated revenues are as follows:

	Years ended March 31,
In 000s'US$	2021	2020
Silver (Ag)	111,191	84,872
Lead (Pb)	50,464	51,966
Zinc (Zn)	21,793	15,780

Additional information is provided in the Company's financial statements and management's discussion and analysis for its most recently completed fiscal year.

The mining industry is intensely competitive and the Company competes with many companies possessing similar or greater financial and technical resources. The Company's competitive position is largely reliant upon its ability to maintain a high margin operation, resulting from relatively high grade resources, and lower production costs in China compared to the costs of other producers outside China. The Company's competitive advantage also results from the quality of its concentrates and its proximity to local smelters.

In Fiscal 2021, ore processed and silver and lead production at the Ying Mining District were in line with the annual guidance, while zinc production was 1% below 7.0 million pounds, the low end of the annual guidance. The all-in sustaining production cost per tonne of ore processed was 1% below the low end of the annual guidance, while the per tonne cash production cost was 1% above $82.5, the high end of the annual guidance.

In Fiscal 2020, silver and zinc production at the Ying Mining District surpassed its annual guidance by 2% and 16%, respectively, while lead production was in line with its annual guidance. The higher silver production was mainly due to the increase in head grades, offset by lower ore production achieved and the higher zinc production was mainly due to the improvement in recovery rates. Silver and lead head grades increased to 309 g/t for silver and 4.6% for lead from the guidance of 290 g/t and 4.3%, respectively. The cash production cost per tonne of ore processed was 1% below its annual guidance while the all-in sustaining production cost was 2% over its annual guidance.

In Fiscal 2021, silver, lead and zinc production at the GC Mine were all above the high end of the annual guidance by 2%, 1% and 13%, respectively, as the ore processed was 2% above the high end of the annual guidance and the zinc head grade was better than the forecast. The per tonne cash production cost and all-in sustaining production cost were 1% and 6%, respectively, below the low end of the annual guidance.

In Fiscal 2020, silver, lead and zinc production at the GC Mine surpassed its annual guidance by 16%, 23% and 18%, respectively, mainly due to an increase of 8% in ore production and an improvement in head grades. Per tonne cash production cost and all-in sustaining production cost were 8% and 10% lower than its annual guidance.

As at March 31, 2021, the Company had 965 employees at Henan Found, 268 at Guangdong Found, 4 at Hunan Yunxiang, 31 at Silvercorp Metals (China) Inc., and 21 at the Vancouver corporate office.

Fiscal 2022 Outlook

Production

For the year ended March 31, 2022 ('Fiscal 2022'), the Company expects to produce approximately 960,000 to 1,010,000 tonnes of ore, which is anticipated to yield approximately 6.4 million to 6.7 million ounces of silver, 65.7 million to 68.9 million pounds of lead, and 26.9 million to 28.5 million pounds of zinc. Fiscal 2022 production guidance represents an anticipated increase of approximately 3% in silver production, 7% to 10% in zinc production, and similar levels in lead production compared to the Fiscal 2021 annual guidance.

In Fiscal 2022, at the Ying Mining District, production is expected to be 670,000 to 700,000 tonnes of ore with grades of 284 g/t silver, 4.2% lead and 0.9% zinc, with expected metal production of 5.7 million to 5.9 million ounces of silver, 57.2 million to 59.8 million pounds of lead, and 7.8 million to 8.1 million pounds of zinc. The cash production cost is expected to be $87.1 to $91.7 per tonne of ore. The all-in sustaining cost is forecasted to be $134.2 to $141.2 per tonne of ore.

In Fiscal 2022, the GC Mine plans to mine and process 290,000 to 310,000 tonnes of ore averaging 86 g/t silver, 1.5% lead and 3.6% zinc with expected metal production of 0.6 million to 0.7 million ounces of silver, 8.5 million to 9.1 million pounds of lead, and 19.1 million to 20.4 million pounds of zinc. The cash production cost is expected to be $55.7 to $59.6 per tonne of ore. The all-in sustaining cost at GC Mine is expected to be $81.3 to 85.6 per tonne of ore.

Capital Expenditures Budget

In Fiscal 2022, the total capital expenditures at the Ying Mining District and the GC Mine are estimated at $38.2 million, including plans to: (i) complete 6,600 m of ramp development tunnelling at estimated capitalized expenditures of $5.6 million; (ii) complete 62,500 m of exploration and other development tunnelling at estimated capitalized expenditures of $21.8 million; (iii) complete 50,000 m of surface diamond drilling at estimated capitalized expenditures of $3.5 million, and (iv) spend $7.3 million on equipment and facilities. The Company also plans to complete and expense 33,600 m of mining preparation tunnelling and 206,900 m of underground diamond drilling.

Other Development Plans

In Fiscal 2022, the Company plans to commence a Phase I 10,000 m drilling program at the La Yesca Project at an estimated cost of $3.3 million. The Company has applied for the necessary drilling permits from the respective Mexican government agencies and is awaiting approval.

The Company plans to initiate an extensive drilling campaign at the Zhonghe Project. The Company will formalize the plan and provide an update on the cost estimates with respect to the Zhonghe Project once the mineral rights transfer contract is executed.

The Company is in the process of applying for permits to build a third tailings facility near the existing tailings facilities at the Ying Mining District. The Company is also considering plans to expand the current milling capacity or build a new mill for future production expansion at the Ying Mining District. There is potential to consolidate mineral properties near the Ying Mining District, and to process ore from Zhonghe Project during its development stage.

Growth by Exploration and Acquisition

The Company continues to pursue future growth opportunities by carrying out exploration programs within existing permit areas at its projects. For example, on May 28, 2020, the Company announced a drill program targeting gold mineralization at the LMW, LME and TLP mines.

15

In Fiscal 2021, the Company commenced extensive drilling programs at the Ying Mining District with two main objectives: i) re-examining areas with existing development and access to potentially define additional resources and reserves, which led to a reduction of 17,010 M or $5.0 million worth of exploration and development tunneling in Fiscal 2021, and ii) testing areas which may have been overlooked for potential gold mineralization for different alteration styles from the typical silver-lead zones.

In addition, the Company continues to evaluate the acquisition of exploration, development and production assets, or the acquisition of or merger with other entities. The Company regularly engages in discussions with respect to such possible opportunities. At any time, discussions and activities may be in progress on a number of initiatives, each at different stages of advancement. Although the Company may from time to time be a party to a number of letters of intent with respect to certain opportunities and other acquisitions, the Company currently does not have any binding agreements or binding commitments to enter into any such transactions. There is no assurance that any potential transaction will be successfully completed.

Specialized Skill and Knowledge

A majority of aspects of our business require specialized skills and knowledge, certain of which are in high demand and in limited supply. Such skills and knowledge include the areas of permitting, engineering, geology, metallurgy, logistical planning, implementation of exploration programs, mine construction and development, mine operation, as well as legal compliance, finance and accounting. We have highly qualified management personnel and staff, an active recruitment program, and believe that persons having the necessary skills are generally available. We have found that we can locate and retain competent employees and consultants in such fields. We do not anticipate having significant difficulty in recruiting other personnel as needed. Training programs are in place for workers that are recruited locally.

Competitive Conditions

The silver exploration and mining business is a competitive business. We compete with numerous other companies and individuals in the search for and the acquisition of quality properties, mineral claims, permits, concessions and other mineral interests, as well as recruiting and retaining qualified employees.

Business Cycles

The mining business is subject to mineral price and investment climate cycles. The marketability of minerals is also affected by worldwide economic and demand cycles. It is difficult to assess if the current commodity prices are long-term trends, and there is uncertainty as to the recovery, or otherwise, of the world economy. If global economic conditions weaken and commodity prices decline as a consequence, a continuing period of lower prices could significantly affect the economic potential of the Company's projects.

International Operations

Our principal operations and assets are located in China. Our operations are exposed to various levels of political, economic and other risks and uncertainties. These risks and uncertainties include, but are not limited to, government regulations (or changes to such regulations) with respect to restrictions on production, export controls, income taxes, royalties, excise and other taxes, expropriation of property, repatriation of profits, environmental legislation, land use, water use, local ownership requirements and land claims of local people, regional and national instability and security, mine safety, and sanctions. The effect of these factors cannot be accurately predicted. See Item 4.3 Chinese Mining Law and 4.4 Risk Factors below.

16

Economic Dependence

The Company's business is not substantially dependent on any contract such as a contract to see the major part of its products or services or to purchase the major part of its requirements for goods, services or raw materials, or on any franchise, license or other agreement to use a patent, formula, trade secret, process or trade name upon which its business depends.

Bankruptcy and Similar Procedures

There is no bankruptcy, receivership or similar proceedings against the Company, nor is the Company aware of any such pending or threatened proceedings. There have not been any voluntary bankruptcy, receivership or similar proceedings by the Company within the three most recently completed financial years or currently proposed for the current financial year.

4.2	Corporate Governance, Safety, Environment and Social Responsibility

The Company is committed to the principles of sustainable development and conducting our activities in an environmentally and socially responsible manner. Our core environmental, social, governance ('ESG') values are: caring for the environment in which we operate; contributing to the long-term development of our host communities; ensuring safe and secure workplaces for our employees; and contributing to the welfare of our employees, local communities, and governments; and operating transparently.

Our inaugural sustainability report (the 'Sustainability Report') released on December 16, 2020 is available on our website at www.silvercorp.ca, and the Company plans to release an updated Fiscal 2021 sustainable report in the second quarter of Fiscal 2022.

(a)	Governance

Our Board oversees the direction and strategy of the business and the affairs of the Company. As at March 31, 2021 and the date of this AIF, the Board is comprised of five directors, four of which are independent. The Board's wealth of experience allows it to effectively oversee the development of corporate strategies and the key risks of the business, provide management with long-term direction, consider and approve major decisions, oversee the business generally and evaluate corporate performance. The Corporate Governance Committee, appointed by the Board, oversee the effective functioning of the Board and the implementation of governance best practices.

We believe that good corporate governance is essential to the effective performance of the Company and plays a significant role in protecting the interests of all stakeholders, while helping to maximize value.

(b)	Health, Safety, and Environment

The Company prioritizes environmental protection, as well as ensuring a safe workplace for all employees and contractors at all of our sites. These corporate philosophies tie directly into the emphasis on efficient process design and management across all aspects of the operation. Significant, ongoing efforts are made to identify and minimize risks, as well as streamline the collection, monitoring and reporting of data. An information technology application that was developed in-house in 2014, the 'Enterprise-Blog', is an instrumental tool used to ensure all mandatory procedures are being performed. In addition, an on-line, real time, monitoring and GPS system was established to further the Company's goal of creating an 'intelligent mine'.

The Company has remained focused on sustainable development since its inception and is dedicated to fulfilling its environmental goals and responsibilities for the communities where it operates. Silvercorp is committed to building green mines and employing the latest design, construction and management practices to ensure our mining environment undergoes timely rehabilitation. The SGX and HZG mines received the Chinese 'National Green Mine' certification in 2015, and the Company's TLP, LME, LMW, and

17

HPG mines at the Ying Mining District and the GC Mine received the Chinese 'Green Mine' certification in Fiscal 2021.

As part of our objective to minimize the impact our operations have on the environment, the Company strives to reduce its energy and water consumption, and to minimize greenhouse gas emissions and the negative impact on water quality.

The Company is deeply committed to protecting the health, safety and well-being of our employees, contractors, suppliers, and communities where we operate. The Company believes that operating safe mines and building a culture of safety are directly related to our operational success and the ability to create long-term value for all our stakeholders. Training for new workers and ongoing training programs are a priority and Silvercorp continuously reviews and refines all standard procedures at our facilities to identify any potential risks associated with each step of the operation.

Moreover, in response to health risks associated with the spread of COVID-19, the Company implemented a number of health and safety measures designed to protect employees and local communities at its operations and no cases were reported among the Company's employees.

(c)	Social Responsibility and Economic Value

The Company is committed to creating sustainable value in the communities where our people work and live. Guided by research conducted by our local offices, the Company participates in, and contributes to numerous community programs that typically center on education and health, nutrition, environmental awareness, local infrastructure and fostering additional economic activity. In addition to the taxes and fees paid to various levels of government in China, in Fiscal 2021, the Company:

• promoted community health and poverty reduction in the local community, with an emphasis on children and seniors, with periodic visits and subsidies;

• donated $0.1 million to institutions in scholarship or education assistance programs to support children's education at the local and national levels; and

• donated $0.2 million to the local community and government as part of the Company's effort to help improve local infrastructure and environmental protection.

4.3	Chinese Mining Law

Currently, all of the Company's material properties are located in China. Under the laws of China, mineral resources are owned by the state, and until 1997, state-owned enterprises have been the principal force in the development of mineral resources.

A new Mineral Resources Law became effective on January 1, 1997, and two regulations were promulgated on February 12, 1998, and later amended in July 2014. The new law provided for equal legal status for domestic enterprises and enterprises with foreign investment, security and transferability of mineral titles as well as the exclusivity of mining rights. The right to explore and exploit minerals is granted by way of exploration and mining rights. The holder of an exploration right has priority in obtaining the mining right to mineral resources within the exploration area provided the holder meets the conditions and requirements specified in the law. The Company's interests in mineral properties are held though joint venture companies established under and governed by the laws of China. The Company's joint venture partners in China include state-sector entities and, like other state-sector entities, their actions and priorities may be dictated by government policies instead of purely commercial considerations.

The Mineral Resources Law is subject to further revisions and in February 2020, the Ministry of Natural Resources ('MNR') submitted the revised draft ('Revised Draft') to the State Council for approval. Although the Revised Draft has not been formally promulgated, a substantial part of the Revised Draft was effectively

18

brought into effect by the Opinions on Promoting the Reform of Mineral Resources Management (Trial)

('Opinions') issued by MNR on December 7, 2019 (effective on January 9, 2020). It is expected that the Revised Draft will have a positive impact on the Chinese mining industry. Firstly, the term of the exploration licence granted upon the first registration is increased to five years from the original three years, which is extendible for two five-year periods (which is increased from the previous two years). Secondly, a competitive assignment system is established for mining rights. Mining rights can only be assigned by governments through public bidding, auction or listing, unless in very limited circumstances such as the projects are related to rare earth and radioactive minerals, or key construction projects approved by the State Council, where mining rights can be granted by written transfer agreement between the government and the applicants. Thirdly, the registration for the assignment of the exploration rights and mining rights to the same mineral resources used to be completed at different levels of government authorities. However, now the assignment of the exploration rights and mining rights are registered at the same level of government - fourteen minerals that are strategically important to the state are governed by MNR, while silver, lead, zinc and other resources are governed by provincial or lower-level governments.

Additionally, companies with a foreign ownership component operating in China may be required to work within a framework which is different from that imposed on domestic Chinese companies. The Chinese government currently allows foreign investment in certain mining projects under central government guidelines. According to the 2020 Edition of the Special Administrative Measures for Access of Foreign Investment ('Negative List') effective July 23, 2020, as long as the mineral resources are not 'tungsten, rare earth and radioactive minerals' in the Negative List, foreign investors can engage in the mining activities in China, either directly or indirectly.

On January 1, 2020, the Regulation for Implementing the Foreign Investment Law ('FIL') came into force in China. FIL and supporting regulations and policies were amended to further open up China and provide foreign-invested enterprises ('FIEs') 'national treatment'. Under FIL, FIEs are treated equal to domestic enterprises in many important respects, including the reduction of previous approval and filing procedures. FIL replaces existing laws on foreign investment passed in China between 1979 and 1990, namely the Law on Sino-Foreign Contractual Joint Ventures ('CJV Law').

Key Impact of FIL on Existing FIEs

Corporate Governance

For existing FIEs, they can retain their corporate structure etc. unchanged for five years starting from the effectiveness of the FIL, i.e., January 1, 2020. Upon the expiration of the five-year transition period (the 'Transition Period'), all FIEs are governed by PRC Company Law.

Upon the expiration of the Transition Period, the highest authority will be transferred from the Board of Directors to the shareholders. The decision-making authority specified in the original Articles of Association of the entity will change such that decisions on significant matters are to be made by the shareholders. The shareholders have the right to elect and dismiss directors, and have broad decision-making power over a company's management. Resolutions on major matters require more than ⅔ of the voting rights of the shareholders. If there is a special agreement on the veto power of the Chinese joint venture party or the FIE in the original Articles of Association of the entity, a supplementary term can be signed to remove or retain such agreement. Under CJV Law, terms of operations were stipulated to be 30 years in a company's articles of association. Under FIL, this 30 year period can be amended to be a longer term.

The below table shows the key differences on corporate structure and governance under the CJV Law and FIL.

	CJV Law	FIL (PRC Company Law)
Highest authority	Board of Directors or Joint Management Committee	Shareholders

19

Powers and duties of highest authority	All major decisions, such as amendments to the Articles of Association, increase and decrease of registered capital, merger or spin-off, assets, mortgage and dissolution	More detailed than those under CJV Law
Voting rules for major issues	Unanimous consent of all directors or members of the Joint Management Committee present at the meeting	Favourable votes of shareholders holding ⅔ or more of the voting rights
Number of directors	No less than 3 directors or members of the Joint Management Committee	3-13 directors for a Board or one executive director
Quorum	⅔ or more of all directors or members of the Joint Management Committee	As determined by shareholders
Term of director	No more than 3 years (can be re-elected)	No more than 3 years (can be re-elected)
Legal representative	Chairman of the Board or the director of the Joint Management Committee	Chairman of the Board, executive director or general manager
Foreign investment ratio	Generally, no less than 25%. There are some restrictions applied	No restrictions - unless otherwise specified in the Negative List
Distribution of profits	In proportion to the contribution of the registered capital	In proportion to the paid-in contribution to the registered capital unless otherwise agreed by the shareholders

Equity Transfer

Under CJV Law, a shareholder needs to obtain consents of all other shareholders if it intends to transfer its shares in the joint venture regardless of whether it is an internal transfer (i.e., transfer to another shareholder if there are more than two shareholders) or it is an external transfer. In contrast, FIL offers more flexible transfer mechanisms - there are no consent requirement if it is an internal transfer. In cases of external transfers, consents of more than half of the other shareholders are required and if any other shareholder refuses the transfer but refuses to buy such shares to be transferred, then such shareholder shall be deemed having agreed with the proposed transfer. The FIL also allows the shareholders to agree on different share transfer mechanisms, which gives more flexibility to shareholders on transfer of shares.

Under FIL, FIEs can participate in government procurement, issue shares, corporate bonds and other forms of financing to the public in accordance with applicable laws. Capital gains within China by FIEs can be freely remitted in RMB or any other foreign currency. In addition to accepting supervision and inspection by applicable regulatory authorities, no organization or individual may illegally restrict the currency, amount, and frequency of remittances.

Foreign Investment Policy and COVID Pandemic

The Chinese government has remained committed to implementing FIL and providing support for FIEs during the COVID pandemic. In February to April 2020, the Ministry of Commerce ('MOFCOM') and the National Development and Reform Commission ('NDRC') issued a comprehensive array of regulations urging local governments to provide special assistance to FIEs, such as expedited licensing approvals, and other methods to help FIEs restore normal production and operation.

20

National Security Review for Foreign Investment and Retaliation against other Jurisdictions' Discriminatory Measures

Nevertheless, China has further developed the national security review for foreign investment and established a formal legal basis for retaliation against other jurisdictions' discriminatory measures. These measures leave great discretion in the hands of the government, and therefore, whether they will constitute a serious obstacle for foreign investors will depend on how they are applied in practice.

Under the FIL, it is reiterated that security review may be conducted for any foreign investment that affects or may affect the national security of China. On December 19, 2020, MOFCOM and NDRC jointly promulgated the Measures for National Security Review of Foreign Investment ('Measures'), taking effect on January 18, 2021. The Measures cover a wide range of industry sectors, from defence and technology involving foreign investment, to critical agricultural production, energy and resources, cultural products and financial services where a foreign investor gains actual control of an investment target. The term 'actual control' is defined quite broadly and includes the following situations: if foreign investors own more than 50 percent of the shares; if foreign investors owns less than 50 percent of the shares, but have sufficient voting rights to exert a material influence over the shareholders' vote and resolutions of the board of directors; or if foreign investors have a significant impact on the target's business decisions-making, human resources, finance or technologies, etc. Further, foreign investors are subject to national security review not only for investing in new projects or acquiring equity or assets, but also for any other types of investment such as nominal shareholders, trust, multiple-layer investments, lease, control by agreement or offshore transactions. Regarding any transaction falling under the Measures, a foreign investor will have to file a notification with the review task force headed by NDRC and MOFCOM. After their review, the foreign investment may be approved, directly prohibited or granted conditional approval.

On September 19, 2020, MOFCOM initially announced the Provisions on the Unreliable Entity List, aiming to punish firms, organizations or individuals that damage national security. Companies that are on the list could be banned from trade and investing in China and face hefty fines or entry restrictions on their employees. On January 9, 2021, MOFCOM further issued the Rules on Counteracting Unjustified ExtraTerritorial Application of Foreign Legislation and Other Measures. A Chinese person or organization that is prohibited or restricted by foreign legislation from engaging in normal economic, trade and related activities with a third State or region or its persons or organizations, must report the situation to the commerce department within 30 days. The commerce department along with other relevant central departments (working mechanism) will then assess a case for its potential violation of international law, impact on China's sovereignty and national security, and impact on Chinese persons or organizations. After assessment, the working mechanism may confirm that there exists unjustified extra-territorial application of foreign legislation/measures and decide that the State Council shall issue a prohibition order.

Civil Code

The National People's Congress passed the Civil Code of PRC, which took effect from January 1, 2021 ('Civil Code'). The Civil Code is an amalgamation of the existing civil and tort related laws and regulations, covering various matters such as private property, contracts, personal privacy, marriage and family, inheritance, and torts. While the Civil Code does not fundamentally or substantially change the civil law regime or the administrative system that affect FIEs, certain specific changes may have impacts on them in relation to their business, legal or compliance models and practices, in the areas such as contracts, secured transactions and civil litigation.

Resources Tax

Mining companies are required to pay several fees and taxes, including but not limited to resources tax for developing taxable resources in China. With the Resources Tax Law coming into effect from September 1, 2020 to replace the old regulations, there is no significant change on the tax burden of mining companies. Generally, silver, lead and zinc are taxable resources, calculated based on the prices of resources. The basic range of tax rates is 2-6% for silver, and 2-10% for lead/zinc. Within this range, provincial governments

21

may stipulate actual rates. Each province also has the power to formulate tax exemption or reduction policies under the Resources Tax Law.

Land Reclamation and Environmental Restoration

Mining companies are regulated to rehabilitate the affected land and to restore biodiversity offset areas around the mines. Before mining activities begin, mining companies shall submit a rehabilitation plan when applying for construction land or mining rights. The existing mining right holders have the same obligation to submit such rehabilitation plan to original approving authorities. On July 16, 2019, MNR revised several regulations, including Geological Environment Protection Provisions of Mines and Measures for the Implementation of the Regulation on Land Reclamation. It is required that the fees for land rehabilitation or reclamation shall be included in the restoration fund established by the mining company. A company has more freedom to use the restoration fund, compared with the previous security bond requirement required to be submitted to the government authorities. In the meantime, the government has strengthened enforcement on the supervision and inspection of the restoration of the mine's geological environment. Non-compliance with the environment restoration obligations may cause fines, rejection of extension of permits, inclusion into the blacklist on the Credit China website, and public interest lawsuits.

4.4	Risk Factors

An investment in the Common Shares of the Company involves a significant degree of risk and ought to be considered a highly speculative investment. The following risk factors, as well as risks not currently known to the Company, could materially adversely affect the Company's future business, operations and financial condition and could cause them to differ materially from the estimates described in the forward-looking statements and information relating to the Company.

COVID-19

The Company's business, operations and financial condition could be materially adversely affected by the outbreak of pandemics or other health crises, such as the outbreak of COVID-19 that was designated as a pandemic by the World Health Organization on March 11, 2020. The international response to the spread of COVID-19 has led to significant restrictions on travel, temporary business closures, quarantines, global stock market volatility, and a general reduction in consumer activity. Such public health crises can result in operating, supply chain and project development delays and disruptions, global stock market and financial market volatility, declining trade and market sentiment, reduced movement of people and labour shortages, and travel and shipping disruption and shutdowns, including as a result of government regulation and prevention measures, or a fear of any of the foregoing, all of which could affect commodity prices, interest rates, credit risk and inflation. In addition, the current COVID-19 pandemic, and any future emergence and spread of similar pathogens could have an adverse impact on global economic conditions which may adversely impact the Company's operations, and the operations of suppliers, contractors and service providers.

The Company may experience business interruptions, including suspended (whether government mandated or otherwise) or reduced operations relating to COVID-19 and other such events outside of the Company's control, which could have a material adverse impact on its business, operations and operating results, financial condition and liquidity.

As at the date of this AIF, the duration of the business disruptions and related financial impact of COVID-19 cannot be reasonably estimated. It is unknown whether and how the Company may be affected if the pandemic persists for an extended period of time.

The Company's exposure to such public health crises also includes risks to employee health and safety. Should an employee, contractor, community member or visitor become infected with a serious illness that has the potential to spread rapidly, this could place the Company's workforce at risk.

22

Fluctuating commodity prices

The Company's sales price for silver is fixed against the Shanghai White Platinum & Silver Exchange as quoted at www.ex-silver.com; lead and zinc are fixed against the Shanghai Metals Exchange as quoted at www.shmet.com; and gold is fixed against the Shanghai Gold Exchange as quoted at www.sge.com.cn.

The Company's revenues, if any, are expected to be in large part derived from the mining and sale of silver, lead, zinc, and gold contained in metal concentrates. The prices of those commodities have fluctuated widely, particularly in recent years, and are affected by numerous factors beyond the Company's control including international and regional economic and political conditions; emerging risks relating to the spread of COVID-19; expectations of inflation; currency exchange fluctuations; interest rates; global or regional supply and demand for jewellery and industrial products containing silver and other metals; sale of silver and other metals by central banks and other holders, speculators and producers of silver and other metals; availability and costs of metal substitutes; and increased production due to new mine developments and improved mining and production methods. The effects of these factors on the price of base and precious metals, and therefore the viability of the Company's exploration projects and mining operations, cannot be accurately predicted and thus the price of base and precious metals may have a significant influence on the market price of the Company's shares and the value of its projects.

If silver and other metal prices were to decline significantly for an extended period of time, the Company may be unable to continue operations, develop its projects, or fulfil obligations under agreements with the Company's joint venture partners or under its permits or licenses.

Recent market events and condition

Over the past several years market events and conditions, including disruptions in the Canadian, United States and international credit markets and other financial systems, along with the uncertainty of the Canadian, United States and global economic conditions which have been heightened due to risks relating to the spread of COVID-19, and the prior decline in precious metal prices, could, among other things, impede access to capital or increase the cost of capital, which would have an adverse effect on the Company's ability to fund its working capital and other capital requirements.

Over the past several years, worldwide securities markets, particularly those in the United States and Canada, have experienced a high level of price and volume volatility. Of note, the share prices of natural resource companies have in the past experienced an extraordinary decline in value and in the number of buyers willing to purchase such securities. In addition, significantly higher redemptions by holders of mutual funds have forced many of such funds (including those holding the Company's securities) to sell such securities with little consideration to the price received.

Therefore, there can be no assurance that significant fluctuations in the trading price of the Company's Common Shares will not occur, or that such fluctuations will not materially adversely impact the Company's ability to raise equity funding without significant dilution to its existing shareholders, or at all.

Estimation of Mineral Resources, Mineral Reserves, mineralization, and metal recovery

There is a degree of uncertainty attributable to the estimation of Mineral Resources, Mineral Reserves, mineralization and corresponding grades being mined or dedicated to future production. Until Mineral Resources, Mineral Reserves or mineralization are actually mined and processed, the quantity of metals and grades must be considered as estimates only. Any material change in quantity of Mineral Resources, Mineral Reserves, mineralization, or grade may affect the economic viability of the Company's projects. In addition, there can be no assurance that precious or other metal recoveries in small-scale laboratory tests will be duplicated in larger scale tests or during production.

23

Interpretations and assumptions of Mineral Resource and Mineral Reserve estimates

Unless otherwise indicated, Mineral Resource and Mineral Reserve estimates presented in this AIF and in the Company's other filings with securities regulatory authorities, press releases and other public statements that may be made from time to time are based upon estimates made by the Company's personnel and independent geologists/mining engineers. These estimates are imprecise and depend upon geologic interpretation and statistical inferences drawn from drilling and sampling analysis, which may prove to be unreliable. The Mineral Resource and Mineral Reserve estimates contained in this AIF have been determined based on assumed future prices, cut-off grades, operating costs and other estimates that may prove to be inaccurate. There can be no assurance that these estimates will be accurate, that Mineral Reserve, Mineral Resource or other mineralization figures will be accurate, or that the mineralization could be mined or processed profitably. The interpretation of drill results, the geology, grade and continuity of the Company's mineral deposits contains inherent uncertainty. Any material reductions in estimates of mineralization, or of the Company's ability to extract this mineralization, could have a material adverse effect on its results of operations or financial condition.

Exploration and development programs

The long-term operation of the Company's business and its profitability is dependent, in part, on the cost and success of its exploration and development programs. Mineral exploration and development involve a high degree of risk and few properties that are explored are ultimately developed into producing mines. There can be no assurance that the Company's mineral exploration and development programs will result in any discoveries of bodies of commercial mineralization. There can also be no assurance that even if commercial quantities of mineralization are discovered that a mineral property will be brought into commercial production. Development of the Company's mineral properties will follow only upon obtaining satisfactory exploration results. Discovery of mineral deposits is dependent upon a number of factors, including the technical skill of the exploration personnel involved. The commercial viability of a mineral deposit once discovered is also dependent upon a number of factors, some of which are the particular attributes of the deposit (such as size, grade and proximity to infrastructure), metals prices and government regulations, including regulations relating to royalties, allowable production, importing and exporting of minerals, and environmental protection. Most of the above factors are beyond the control of the Company. As a result, there can be no assurance that the Company's exploration and development programs will yield reserves to replace or expand current resources. Unsuccessful exploration or development programs could have a material adverse effect on the Company's operations and profitability.

Economic factors affecting the Company

Many industries, including the mining industry, are impacted by market conditions. Some of the key impacts of the recent financial market turmoil include risks relating to COVID-19, contraction in credit markets resulting in a widening of credit risk, devaluations and high volatility in global equity, commodity, foreign exchange and precious metals markets, and a lack of market liquidity. A continued or worsened slowdown in the financial markets or other economic conditions, including but not limited to, consumer spending, employment rates, business conditions, inflation, fuel and energy costs, consumer debt levels, lack of available credit, the state of the financial markets, interest rates, and tax rates may adversely affect the Company's growth and profitability. Specifically: the volatility of silver, lead, zinc and gold prices may impact the Company's revenues, profits, losses and cash flow; volatile energy prices, commodity and consumable prices and currency exchange rates would impact the Company's production costs; and the devaluation and volatility of global stock markets may impact the valuation of the Company's equity and other securities. These factors could have a material adverse effect on the Company's financial condition and results of operations.

Timing, estimated amount, capital and operating expenditures and economic returns of future production

There are no assurances if and when a particular mineral property of the Company can enter into production. The amount of future production is based on the estimates prepared by or for the Company.

24

The capital and operating costs to take the Company's projects into production or maintain or increase production levels may be significantly higher than anticipated. Capital and operating costs of production and economic returns are based on estimates prepared by or for the Company and may differ significantly from their actual values. There can be no assurance that the Company's actual capital and operating costs will not be higher than currently anticipated. In addition, the construction and development of mines and infrastructure are complex. Resources invested in construction and development may yield outcomes that may differ significantly from those anticipated by the Company.

Integration of future acquisitions into existing operations

The Company may make select future acquisitions. If the Company does make acquisitions, any positive effect on the Company's results will depend on a variety of factors, including, but not limited to: integrating the operations of an acquired business or property in a timely and efficient manner; maintaining the Company's financial and strategic focus while integrating the acquired business or property; implementing uniform standards, controls, procedures and policies at the acquired business, as appropriate; and to the extent that the Company makes an acquisition outside of markets in which it has previously operated, conducting and managing operations in a new operating environment.

Acquiring additional businesses or properties could place pressure on the Company's cash reserves if such acquisitions involve cash consideration or if such acquisitions involve share consideration existing shareholders may experience dilution.

The integration of the Company's existing operations with any acquired business may require significant expenditures of time, attention and funds. Achievement of the benefits expected from consolidation may require the Company to incur significant costs in connection with, among other things, implementing financial and planning systems. The Company may not be able to integrate the operations of a recently acquired business or restructure the Company's previously existing business operations without encountering difficulties and delays. In addition, this integration may require significant attention from the Company's management team, which may detract attention from the Company's day-to-day operations.

Over the short-term, difficulties associated with integration could have a material adverse effect on the Company's business, operating results, financial condition and the price of the Company's Common Shares. In addition, the acquisition of mineral properties may subject the Company to unforeseen liabilities, including environmental liabilities, which could have a material adverse effect on the Company. There can be no assurance that any future acquisitions will be successfully integrated into the Company's existing operations.

Permits and licenses for mining and exploration in China

All Mineral Resources and Mineral Reserves of the Company's subsidiaries are owned by their respective joint venture entities in China. Mineral exploration and mining activities in China may only be conducted by entities that have obtained or renewed exploration or mining permits and licenses, and other certificates in accordance with the relevant mining laws and regulations. These permits and license are also subject to annual inspection by government authorities. Failure to pass the annual inspections may result in penalties. No guarantee can be given that the necessary exploration and mining permits and licenses will be issued to the Company or, if they are issued, that they will be renewed, or if renewed under reasonable operational and/or financial terms, or in a timely manner, or that the Company will be in a position to comply with all conditions that are imposed. Please see 'Table 1, Mining licenses', on page 36 for information on the current status of mining licences at the Ying Project.

Nearly all mining projects require government approvals and permits relating to environmental, social, land and water usage, community, and other matters, including those discussed in Sections 20 of the respective NI 43-101 Technical Reports on the Company's material properties (see the Ying Report and the GC Report respectively). Some of the permits or certificates that are subject to renewal in the next three years at the GC Mine, not otherwise discussed in the GC Report include:

25

Permit	Expiry Date	Approving Authority
Safety Production Permit	September 03, 2023	Bureau of Safety Production and Inspection of Yunfu City, Guangdong Province
Dry Stacking and Filling Safety Production Permit	September 03, 2023	Bureau of Safety Production and Inspection of Yunfu City, Guangdong Province
Pollutant Discharge Permit	August 30, 2025	Environment Protection Administration of Yunfu, Guangdong Province

There can be no certainty that approvals necessary to develop and operate mines on the Company's properties will be granted or renewed in a timely and/or economical manner, or at all.

Title to properties

The validity of mining or exploration titles or claims or rights, which constitute most of our property holdings, can be uncertain and may be contested. Our properties may be subject to prior unregistered liens, agreements or transfers, indigenous land claims, or undetected title defects. In some cases, we do not own or hold rights to the mineral concessions we mine. We have not conducted surveys of all the claims in which we hold direct or indirect interests and therefore, the precise area and location of such claims may be in doubt. No assurance can be given that applicable governments will not revoke or significantly alter the conditions of the applicable exploration and mining titles or claims, or that such exploration and mining titles or claims will not be challenged or impugned by third parties.

We may be unable to operate our properties as expected, or to enforce our rights to our properties. Any defects in title to our properties, or the revocation of our rights to mine, could have a material adverse effect on our operations and financial condition.

We operate in countries with developing mining laws, and changes in such laws could materially impact our rights or interests to our properties. We are also subject to expropriation risk, including the risk of expropriation or extinguishment of property rights based on a perceived lack of development or advancement. Expropriation, extinguishment of rights and any other such similar governmental actions would likely have a material adverse effect on our operations and profitability.

In the jurisdictions in which we operate, legal rights applicable to mining concessions are different and separate from legal rights applicable to surface lands. Accordingly, title holders of mining concessions in many jurisdictions must agree with surface land owners on compensation in respect of mining activities conducted on such land. We do not hold title to all of the surface lands at many of our operations and rely on contracts or other similar rights to conduct surface activities.

Non-controlling interest shareholders

The Company's interests in various projects may, in certain circumstances, become subject to the risks normally associated with the conduct of non-controlling interest shareholders. The existence or occurrence of one or more of the following events could have a material adverse impact on the Company's profitability or the viability of its interests held with non-controlling interest shareholders, which could have a material adverse impact on the Company's business prospects, results of operations and financial conditions: (i) disagreements with non-controlling interest shareholders on how to conduct exploration; (ii) inability of non-controlling interest shareholders to meet their obligations to the applicable entity or third parties; and (iii) disputes or litigation between shareholders regarding budgets, development activities, reporting requirements and other matters.

Acquisition of commercially mineable mineral rights

Most exploration projects do not result in the discovery of commercially mineable ore deposits and no assurance can be given that any particular level of recovery of Mineral Reserves will be realized or that any identified mineral deposit will ever qualify as a commercially mineable (or viable) ore body which can be legally and economically exploited.

26

The Company's future growth and productivity will depend, in part, on its ability to identify and acquire additional mineral rights, and on the costs and results of continued exploration and development programs. Mineral exploration is highly speculative in nature and is frequently non-productive. Substantial expenditures are required to: establish mineral reserves through drilling and metallurgical and other testing techniques; determine metal content and metallurgical recovery processes to extract metal from the ore; and construct, renovate or expand mining and processing facilities.

In addition, if the Company discovers a mineral deposit, it would likely take at least several years from the initial phases of exploration until production is possible. During this time, the economic feasibility of production may change.

The Company's success at completing any acquisitions will depend on a number of factors, including, but not limited to: identifying acquisitions that fit the Company's business strategy; negotiating acceptable terms with the seller of the business or property to be acquired; and obtaining approval from regulatory authorities in the jurisdictions of the business or property to be acquired. As a result of these uncertainties, there can be no assurance that the Company will successfully acquire additional mineral rights.

Financing

The Company has limited financial resources. If more of the Company's exploration programs are successful in establishing ore of commercial tonnage and grade, additional funds will be required for the development of the ore body and to place it in commercial production. Therefore, the Company's ability to continue its exploration and development activities, if any, will depend in part on the Company's ability to obtain suitable financing.

The Company intends to fund its plan of operations from working capital, proceeds of production, external financing, strategic alliances, sale of property interests and other financing alternatives. The sources of external financing that the Company may use for these purposes include project or bank financing, or public or private offerings of equity or debt. One source of future funds presently available to the Company is through the sale of equity capital. There is no assurance this source of financing will continue to be available as required or on suitable terms, or at all. If it is available, future equity financings may result in substantial dilution to shareholders. Another alternative for the financing of further exploration would be the offering by the Company of an interest in the properties to be earned by another party or parties carrying out further exploration or development thereof. There can be no assurance the Company will be able to conclude any such agreements, on favourable terms or at all. The failure to obtain financing could have a material adverse effect on the Company's growth strategy and results of operations and financial condition.

Competition

The mining industry in general is intensely competitive and there is no assurance that a ready market will exist for the sale of ore, or concentrate, by the Company. Marketability of natural resources which may be discovered by the Company will be affected by numerous factors beyond the control of the Company, such as market fluctuations, the proximity and capacity of natural resource markets and processing equipment, government regulations including regulations relating to prices, royalties, land tenure, land use, importing and exporting of minerals and environmental protection. The exact effect of such factors cannot be predicted but they may result in the Company not receiving an adequate return on its capital.

The Company may be at a competitive disadvantage in acquiring additional mining properties because it must compete with other individuals and companies, many of which have greater financial resources, operational experience and technical capabilities than the Company. The Company may also encounter increasing competition from other mining companies in its efforts to hire experienced mining professionals. Competition for exploration resources at all levels is currently very intense, particularly affecting the availability of manpower. Increased competition could adversely affect the Company's ability to attract necessary capital funding or acquire suitable producing properties or prospects for mineral exploration in the future.

27

Operations and political conditions

All the Company's material operations are located in China. These operations are subject to the risks normally associated with conducting business in China, which has different regulatory and legal standards than North America. Some of these risks are more prevalent in countries which are less developed or have emerging economies, including uncertain political and economic environments, as well as risks of civil disturbances or other risks which may limit or disrupt a project, restrict the movement of funds or result in the deprivation of contractual rights or the taking of property by nationalization or expropriation without fair compensation, risk of adverse changes in laws or policies, increases in foreign taxation or royalty obligations, license fees, permit fees, delays in obtaining or the inability to obtain necessary governmental permits, limitations on ownership and repatriation of earnings, and foreign exchange controls and currency devaluations.

In addition, the Company may face import and export regulations, including export restrictions, disadvantages of competing against companies from countries that are not subject to similar laws, restrictions on the ability to pay dividends offshore, and risk of loss due to disease and other potential endemic health issues. Although the Company is not currently experiencing any significant or extraordinary problems in China arising from such risks, there can be no assurance that such problems will not arise in the future. The Company currently does not carry political risk insurance coverage.

The Company's interests in its mineral properties are held through joint venture companies established under and governed by the laws of China. The Company's joint venture partners in China include state-sector entities and, like other state-sector entities, their actions and priorities may be dictated by government policies instead of purely commercial considerations. Additionally, companies with a foreign ownership component operating in China may be required to work within a framework which is different from that imposed on domestic Chinese companies. The Chinese government currently allows foreign investment in certain mining projects under central government guidelines. There can be no assurance that these guidelines will not change in the future. See Item 4.3 Chinese Mining Law above.

Regulatory environment in China

The Company's principal operations are in China. The laws of China differ significantly from those of Canada and all such laws are subject to change. Mining is subject to potential risks and liabilities associated with pollution of the environment and disposal of waste products occurring as a result of mineral exploration and production.

Failure to comply with applicable laws and regulations may result in enforcement actions and may also include corrective measures requiring capital expenditures, installation of additional equipment or remedial actions. Parties engaged in mining operations may be required to compensate those suffering loss or damage by reason of mining activities and may have civil or criminal fines or penalties imposed for violations of applicable laws and regulations.

China's legislation is undergoing a relatively fast transformation with some old laws superseded by newly enacted laws. New laws and regulations, amendments to existing laws and regulations, administrative interpretation of existing laws and regulations, or more stringent enforcement of existing laws and regulations could create risks or uncertainty for investors in mineral projects or have a material adverse impact on future cash flow, results of operations and the financial condition of the Company.

In addition, China has further strengthened its national security review of foreign investment. The Measures will continue to create an additional layer of uncertainty with respect to foreign investment. Investment plans, timetables, terms and conditions for closing for investment must take into account the timing and contingency of obtaining approval from the national security review process. See Item 4.3 Chinese Mining Law above.

28

Regulatory environment in Mexico

The La Yesca Project is located in Mexico and is subject to extensive laws and regulations governing various matters including, but not limited to, exploration, development, production, price controls, exports, taxes, mining royalties, environmental matters, labor standards, expropriation of property, maintenance of mining claims, land use, land claims of local and indigenous people, water use, waste disposal, power generation, protection and remediation of the environment, reclamation, historic and cultural resource preservation, mine safety, occupational health, and the management and use of toxic substances and explosives, including handling, storage and transportation of hazardous substances.

Such laws and regulations may require the Company to obtain licenses, permits and consents from various governmental authorities and indigenous groups. Failure to comply with applicable laws and regulations, including licensing and permitting requirements, may result in civil or criminal fines, penalties or enforcement actions, including orders issued by regulatory or judicial authorities enjoining or curtailing operations, requiring corrective measures, requiring the installation of additional equipment, requiring remedial actions or imposing additional local or foreign parties as joint venture partners, any of which could result in significant expenditures or loss of income by the Company. The Company may also be required to compensate private parties suffering loss or damage by reason of a breach of such laws, regulations, licensing requirements or permitting requirements.

The Company's income and its mining, exploration and development projects, could be adversely affected by amendments to such laws and regulations, by future laws and regulations, by more stringent enforcement of current laws and regulations, by changes in the policies of Mexico, Canada and other applicable jurisdictions affecting investment, mining and repatriation of financial assets, by shifts in political attitudes in Mexico and by exchange controls and currency fluctuations. The effect, if any, of these factors cannot be accurately predicted. Further, there can be no assurance that the Company will be able to obtain or maintain all necessary licenses and permits that may be required to carry out exploration, development and mining operations at the La Yesca Project.

The costs of discovering, evaluating, planning, designing, developing, constructing, operating and closing the Company's mining, exploration and development activities and operations in compliance with such laws and regulations are significant. It is possible that the costs and delays associated with compliance with such laws and regulations, and new taxes, could become such that the Company would not proceed with mining, exploration and development at one or more of its properties. Moreover, it is possible that future regulatory developments, such as increasingly strict environmental protection laws, regulations and enforcement policies thereunder, and claims for damages to property and persons resulting from the Company's mining, exploration and development projects could result in substantial costs and liabilities for the Company, such that the Company would halt or not proceed with mining, exploration and development at one or more of its properties.

Environmental risks

The Company's activities are subject to extensive laws and regulations governing environmental protection and employee health and safety, including environmental laws and regulations in China. These laws address emissions into the air, discharges into water, management of waste, management of hazardous substances, protection of natural resources, antiquities and endangered species, and reclamation of lands disturbed by mining operations. The Company's Chinese subsidiaries are required to have been issued environmental permits and safety production permits with various expiration dates. These permits are also subject to annual inspection by government authorities. Failure to pass the annual inspections may result in penalties. No guarantee can be given that the necessary permits will be issued to the Company or, if they are issued, that they will be renewed, or if renewed under reasonable operational and/or financial terms, or in a timely manner, or that the Company will be in a position to comply with all conditions that are imposed.

Nearly all mining projects require government approval and permits relating to environmental, social, land and water usage, community matters, and other matters, including those discussed in Sections 20 of the

29

respective NI 43-101 Technical Reports on the Company's material properties (see the Ying Report and the GC Report respectively, each as defined below).

There are also laws and regulations prescribing reclamation activities on some mining properties. Environmental legislation in many countries, including China, is evolving and the trend has been toward stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects and increasing responsibility for companies and their officers, directors and employees. Compliance with environmental laws and regulations may require significant capital outlays on behalf of the Company and may cause material changes or delays in the Company's intended activities. There can be no assurance that the Company has been or will be at all times in complete compliance with current and future environmental, and health and safety laws, and the status of permits will not materially adversely affect the Company's business, results of operations or financial condition. It is possible that future changes in these laws or regulations could have a significant adverse impact on some portion of the Company's business, causing the Company to re-evaluate those activities at that time. The Company's compliance with environmental laws and regulations entail uncertain costs.

Dependence on management and key personnel

The executive director and the China operational management team all have extensive experience in the mineral resources industry in China. Most of the non-executive directors also have extensive experience in mining and/or exploration (or as advisors to companies in the field). The Company's success depends to a significant extent upon its ability to retain, attract and train key management personnel, both in Canada and in China.

The Company depends on the services of a number of key personnel, including the Chief Executive Officer, Chief Financial Officer, and the China operational management team, the loss of any one of whom could have an adverse effect on the Company's operations.

The Company's ability to manage growth effectively will require it to continue to implement and improve management systems and to recruit and train new employees. The Company cannot be assured that it will be successful in attracting and retaining skilled and experienced personnel.

Foreign exchange rate fluctuations

The Company reports its financial statements in US dollars. The functional currency of the head office, Canadian subsidiaries and all intermediate holding companies is the Canadian dollar while the functional currency of all Chinese subsidiaries is Chinese Renminbi. The Company is exposed to foreign exchange risk when the Company undertakes transactions and holds assets and liabilities in currencies other than its functional currencies. The fluctuation of the exchange rate between the reporting currency and its functional currencies may materially and adversely affect the Company's financial position.

Insurance

The Company's mining activities are subject to the risks normally inherent in the industry, including, but not limited, to environmental hazards, flooding, fire, periodic or seasonal hazardous climate and weather conditions, unexpected rock formations, industrial accidents and metallurgical and other processing problems. These risks could result in damage to, or destruction of, mineral properties, production facilities or other properties; personal injury; environmental damage; delays in mining; increased production costs; monetary losses; and possible legal liability. The Company may become subject to liability which it cannot insure or may elect not to insure due to high premium costs or other reasons. Where considered practical to do so, the Company maintains insurance against risks in the operation of its business in amounts which the Company believes to be reasonable. Such insurance, however, contains exclusions and limitations on coverage. The Company cannot provide any assurance that such insurance will continue to be available,

30

be available at economically acceptable premiums or be adequate to cover any resulting liability. In some cases, coverage is not available or considered too expensive relative to the perceived risk.

Risks and hazards of mining operations

Mining is inherently dangerous and the Company's operations are subject to a number of risks and hazards including, without limitation: environmental hazards; discharge of pollutants or hazardous chemicals; industrial accidents; failure of processing and mining equipment; labour disputes; supply problems and delays; encountering unusual or unexpected geologic formations or other geological or grade problems; encountering unanticipated ground or water conditions; cave-ins, pit wall failures, flooding, rock bursts and fire; periodic interruptions due to inclement or hazardous weather conditions; equipment breakdown; other unanticipated difficulties or interruptions in development, construction or production; other acts of God or unfavourable operating conditions; and health and safety risks associated with spread of COVID-19 pandemic, and any future emergence and spread of similar pathogens.

Such risks could result in damage to, or destruction of, mineral properties or processing facilities, personal injury or death, loss of key employees, environmental damage, delays in mining, monetary losses and possible legal liability. Satisfying such liabilities may be very costly and could have a material adverse effect on the Company's future cash flow, results of operations and financial condition.

Conflicts of interest

Conflicts of interest may arise as a result of the directors and officers of the Company also holding positions as directors and/or officers of other companies. Some of those persons who are directors and officers of the Company have and will continue to be engaged in the identification and evaluation of assets and businesses and companies on their own behalf and on behalf of other companies, and situations may arise where the directors and officers may be in direct competition with the Company. Conflicts, if any, will be subject to the procedures and remedies under the Business Corporations Act (British Columbia).

Internal control over financial reporting as per the requirements of the Sarbanes-Oxley Act

Management of the Company is responsible for establishing and maintaining an adequate system of internal control over financial reporting, and used the Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ('COSO') to evaluate, with the participation of the CEO and CFO, the effectiveness of internal controls. The Company's internal control over financial reporting includes:

• maintaining records, that in reasonable detail, accurately and fairly reflect our transactions and dispositions of the assets of the Company;

• providing reasonable assurance that transactions are recorded as necessary for preparation of our consolidated financial statements in accordance with generally accepted accounting principles;

• providing reasonable assurance that receipts and expenditures are made in accordance with authorizations of management and the directors of the Company; and

• providing reasonable assurance that unauthorized acquisition, use or disposition of company assets that could have a material effect on the Company's consolidated financial statements would be prevented or detected on a timely basis.

Based on this evaluation, management concluded that the Company's internal control over financial reporting based on the criteria set forth in Internal Control - Integrated Framework (2013) issued by COSO was effective as of March 31, 2021 and provided a reasonable assurance of the reliability of the Company's financial reporting and preparation of the financial statements.

31

No matter how well a system of internal control over financial reporting is designed, any system has inherent limitations. Even systems determined to be effective can provide only reasonable assurance of the reliability of financial statement preparation and presentation. Also, controls may become inadequate in the future because of changes in conditions or deterioration in the degree of compliance with the Company's policies and procedures.

The failure to achieve and maintain the adequacy of our internal control over financial reporting on a timely basis could result in the loss of investor confidence in the reliability of the financial statements, which in turn could harm the business and negatively impact the trading price of shares or market value of other securities. In addition, any failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm the operating results or cause to fail to meet the reporting obligations. There can be no assurance that the Company will be able to remediate material weaknesses, if any, identified in future periods, or maintain all of the controls necessary for continued compliance, and there can be no assurance that the Company will be able to retain sufficient skilled finance and accounting personnel, especially in light of the increased demand for such personnel among publicly traded companies. Future acquisitions of companies may provide the Company with challenges in implementing the required processes, procedures and controls in the acquired operations. Acquired companies may not have disclosure controls and procedures or internal control over financial reporting that are as thorough or effective as those required by securities laws currently applicable to the Company.

Outcome of current or future litigation or regulatory actions

Due to the nature of its business, the Company may be subject to numerous regulatory investigations, claims, lawsuits and other proceedings in the ordinary course of its business. The results of these legal proceedings cannot be predicted with certainty due to the uncertainty inherent in litigation, including the discovery of evidence process, the difficulty of predicting decisions of judges and juries and the possibility that decisions may be reversed on appeal. There can be no assurances that these matters will not have a material adverse effect on the Company's business.

No assurance can be given with respect to the ultimate outcome of current or future litigation or regulatory proceedings, and the amount of any damages awarded or penalties assessed in such a proceeding could be substantial. In addition to monetary damages and penalties, the allegations made in connection with the proceedings may have a material adverse effect on the reputation of the Company and may impact its ability to conduct operations in the normal course.

Litigation and regulatory proceedings also require significant resources to be expended by the directors, officers and employees of the Company and as a result, the diversion of such resources could materially affect the ability of the Company to conduct its operations in the normal course of business. Significant fees and expenses may be incurred by the Company in connection with the investigation and defense of litigation and regulatory proceedings. The Company may also be obligated to indemnify certain directors, officers, employees and experts for additional legal and other expenses pursuant to such proceedings, which additional costs may be substantial and could have a negative effect on the Company's future operating results. The Company may be able to recover certain costs and expenses incurred in connection with such matters from its insurer. However, there can be no assurance regarding when or if the insurer will reimburse the Company for such costs and expenses.

Bringing actions and enforcing judgments under U.S. securities laws

Investors in the U.S. or in other jurisdictions outside of Canada may have difficulty bringing actions and enforcing judgments against the Company, its directors, its executive officers and some of the experts named in this AIF based on civil liabilities provisions of the federal securities laws, other laws in the U.S. state(s) in or the equivalent laws of other jurisdictions of residence.

The Company's investment in New Pacific Metals Corp.

The Company is a strategic investor in New Pacific Metals, a Canadian public company listed on the TSX under the symbol 'NUAG' and NYSE American under the symbol 'NEWP'. As at March 31, 2021, the Company owned 43,917,216 or 28.6% interest in New Pacific Metals. New Pacific Metals is an exploration company currently in the business of acquiring and exploring mineral properties. Investments in junior mining companies involve volatile share prices, liquidity risk, and may result in possible loss of principal. New Pacific Metals has no revenue from operations and no ongoing mining operations of any kind.

Resource exploration and development is a speculative business and involves a high degree of risk, including, among other things, unprofitable efforts resulting both from the failure to discover mineral deposits and from finding mineral deposits which, though present, are insufficient in size and grade at the then prevailing market conditions to return a profit from production. The marketability of natural resources which may be acquired or discovered by New Pacific Metals will be affected by numerous factors beyond the control of New Pacific. These factors include market fluctuations, the proximity and capacity of natural resource markets, and government regulations, including regulations relating to prices, taxes, royalties, land use, importing and exporting of minerals and environmental protection. The exact effect of these factors cannot be accurately predicted, but the combination of these factors may result in the Company not receiving an adequate return on invested capital or the possible loss of principal.

Substantial expenditures are required to establish ore reserves through drilling, metallurgical, and other testing techniques, determine metal content and metallurgical recovery processes to extract metal from the ore, and construct, renovate, or expand mining and processing facilities. No assurance can be given that any level of recovery of ore reserves will be realized or that any identified mineral deposit, even if it is established to contain an estimated resource, will ever qualify as a commercial mineable ore body, which can be legally and economically exploited.

In addition to the high degree of risk associated with investing in junior exploration mining companies, the Company's investment in New Pacific Metals entails an additional risk by virtue of the fact that its projects are located in Bolivia. Bolivia's history since the mid-1960s has been one of political and economic instability under various governments. Since 2006, the government has frequently intervened in the national economy and social structure, including periodically imposing various controls, the effects of which have been to restrict the ability of both domestic and foreign companies to operate freely. Although Silvercorp believes that the current conditions in Bolivia are relatively stable and conducive to conducting business, New Pacific Metals' current and future mineral exploration and mining activities in Bolivia are exposed to various levels of political, economic, and other risks and uncertainties. These risks and uncertainties include, but are not limited to, co-operatives and community blockades, terrorism, hostage taking, military repression, extreme fluctuations in currency exchange rates, high rates of inflation, political and labour unrest, the risks of war or civil unrest, expropriation and nationalization, renegotiation or nullification of existing concessions, licenses, permits and contracts, illegal mining, changes in taxation policies, restrictions on foreign exchange and repatriation, changing political conditions, currency controls, and governmental regulations that favour or require the awarding of contracts to local contractors or require foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction. Given the political instability and social unrest in Bolivia following the general elections held on October 20, 2019, there is no assurance that New Pacific will be successful in obtaining ratification of the mining production contract ('MPC') it signed with Corporación Minera de Bolivia (COMIBOL) in a timely manner or at all, or that they will be obtained on reasonable terms. New Pacific Metals cannot predict the government's positions on foreign investment, mining concessions, land tenure, environmental regulation, community relations, or taxation. A change in government positions on these issues could adversely affect the ratification of the MPC and New Pacific Metals' business.

The Company's investment in Whitehorse Gold Corp.

The Company is a strategic investor in Whitehorse Gold, a Canadian public company listed on the TSX-V under the symbol 'WHG'. As at March 31, 2021, the Company owned 11,514,285 Whitehorse Gold common shares or 26.99% interest in Whitehorse Gold (29.50% after the 2021 private placements).

33

Whitehorse Gold is a junior exploration company currently in the business of acquiring and exploring mineral properties. Investments in junior mining companies involve volatile share prices, liquidity risk, and may result in possible loss of principal. Whitehorse Gold has no revenue from operations and no ongoing mining operations of any kind.

Long-term operation of Whitehorse Gold's business and its profitability are dependent, in part, on the cost and success of its exploration and future development programs. Mineral exploration and development involve a high degree of risk and historically few properties that are explored are ultimately developed into producing mines. There is no assurance that Whitehorse Gold's mineral exploration and future development programs will result in any discoveries, expansions of mineral resources or the definition of mineral reserves. There is also no assurance that, even if commercially viable quantities of mineral resources or mineral reserves are discovered, a mineral property will be brought into commercial production. Development of Whitehorse Gold's mineral properties will only commence if it obtains satisfactory exploration results. Discovery of mineral deposits is dependent upon a number of factors, including the technical skill of the exploration geoscientists involved. The commercial viability of a mineral deposit is also dependent upon a number of factors including: the particular attributes of the deposit such as size, grade and proximity to infrastructure; metal prices; and government regulations including regulations relating to royalties, allowable production, importing and exporting of minerals and environmental protection. Most of the above factors are beyond the control of Whitehorse Gold. Unsuccessful exploration or development programs could have a material adverse impact on Whitehorse Gold's operations and profitability.

In addition, Whitehorse Gold's mineral projects are subject to a number of risks that may make it less successful than anticipated, including, without limitation: (a) delays or higher than expected exploration costs; (b) negative technical results and/or technical results that fail to deliver the required returns to render the ongoing development of the Skukum Gold Project economic; (c) delays in receiving environmental permits and/or social license from indigenous groups; (d) delays in receiving permits; (e) delays or higher than expected costs in obtaining the necessary equipment or services to build and operate the Skukum Gold Project; and (f) adverse mining conditions may delay and hamper the ability of Whitehorse Gold to produce the expected quantities of minerals.

First Nation interests and rights as well as related consultation issues may impact Whitehorse Gold's ability to pursue exploration, development and mining at its properties. Whitehorse Gold intends to communicate and consult with First Nations communities in order to foster a positive relationship with those groups but there is no assurance that claims or other assertions of rights by First Nation communities or consultation issues will not arise on or with respect to Whitehorse Gold's properties or activities. Such claims and issues could result in significant costs and delays or materially restrict Whitehorse Gold's activities.

Cybersecurity Risks

The Company is subject to cybersecurity risks including unauthorized access to privileged information, destroy data or disable, degrade or sabotage our systems, including through the introduction of computer viruses. Although we take steps to secure our configurations and manage our information system, including our computer systems, internet sites, emails and other telecommunications, and financial/geological data, there can be no assurance that measures we take to ensure the integrity of our systems will provide protection, especially because cyberattack techniques used change frequently or are not recognized until successful. The Company has not experienced any material cybersecurity incident in the past, but there can be no assurance that the Company would not experience in the future. If our systems are compromised, do not operate properly or are disable, we could suffer financial loss, disruption of business, loss of geology data which could affect our ability to conduct effective mine planning and accurate mineral resources estimates, loss of financial data which could affect our ability to provide accurate and timely financial reporting.

The authors of the Technical Report all qualify as independent Qualified Persons (QPs).

Portions of the following information are based on the assumptions, qualifications and procedures described in the Ying Report, which are not fully described herein. The full text of the Ying Report which is available for review on SEDAR at www.sedar.com is incorporated by reference in this AIF.

Project Description, Location and Access

The Property is situated in central China in western Henan Province near the town of Luoning. The term 'Ying District' is used to describe a 100 sq. km rectangular area bounded by latitude 34°07'N to 34°12'N and longitude 111°14'E to 111°23'E. Within this district block, Silvercorp has three principal centres of operation, within which six mining projects are located.

Silvercorp, through its wholly owned subsidiary Victor Mining Ltd, is party to a cooperative joint venture agreement dated 12 April 2004 under which it earned a 77.5% interest in Henan Found Mining Co. Ltd (Henan Found), the Chinese company holding (with other assets) the Ying silver, lead, and zinc project (the Ying Project). In addition, Silvercorp, through its wholly owned subsidiary Victor Resources Ltd, is party to a cooperative agreement dated 31 March 2006, under which it initially obtained a 60% interest in Henan Huawei Mining Co. Ltd (Henan Huawei), the beneficiary owner of the project in Haopinggou (the HPG Project) and the project in Longmen (the LME Project). Since that time, Silvercorp's interest in Henan Huawei has increased to 80%.

The Ying Property is covered by four major contiguous mining licenses. The total area of the four mining licenses is 68.59 sq km. Table 1 lists their names, license numbers, areas and expiry dates. All Tables are numbered relative to their position in the AIF.

Total			68.59

Note: Mining license for TLP , LME and LMW extended since Ying Report date.

In addition, mining is only permitted between prescribed elevations as follows:

• Yuelianggou Mining License - 1,060 m and 0 m elevations

• Haopinggou Mining License - 955 m and the 365 m elevations

• Tieluping-Longmen Mining License - 1,250 m and the 700 m elevations

• Doncaogau Mining License - 1,087 m and the 605 m elevations

Henan Found's policy has been to initiate applications to the relevant government departments so that exploration permits are reissued beneath the lower boundary of the mining permit areas in accordance with the 'Mineral Resources Law of the People's Republic of China' and the integration policy of mineral resource development issued by the Ministry of Land and Resources of China and the Henan Provincial Government.

The existing mining licenses cover all the active exploration and mining areas discussed in this Technical Report. Mining licenses are subject to mining-right usage fees (a fixed annual charge), mineral resource compensation fees, and applicable mineral resource taxes. The renewal of mining licenses and extending of mining depth and boundaries occur in the ordinary course of business as long as mineral resources exist, are defined, the required documentation is submitted, and the applicable government resources taxes and fees are paid. The mining licenses give the right to carry out full mining and mineral processing operations in conjunction with safety and environmental certificates. The safety certificates for Silvercorp's mining activities have been issued by the Department of Safety, Production and Inspection of Henan Province. Environmental certificates have been issued by the Department of Environmental Protection of Henan Province.

Surface rights for mining purposes are not included in the licenses, but Silvercorp has acquired surface rights for mining and milling activities by effecting payment of a purchase fee based on the appraised value of the land. Subject to negotiation, some land use compensation fees may also be due to the local farmers if their agricultural land is disturbed by exploratory work.

China has an established Mining Code that defines the mining rights guaranteed by the government of China.

China has a 13% Value Added Tax (VAT) on sales of concentrates and on articles such as materials and supplies. The VAT paid on materials purchased for mining is returned to Silvercorp as an incentive to mine in China. There is no VAT on labour. In addition, Silvercorp also pays a VAT surtax, which amounts to approximately 1.6% of sales, and mineral resources tax is currently levied at approximately 3% of sales. The income tax rate is 25%.

There are no known or recognized environmental issues that might preclude or inhibit a mining operation in this area. Some major land purchases may be required in the future for mine infrastructure purposes (such as for additional processing plant requirements, waste disposal, offices and accommodations). There are no significant factors and risks that may affect access, title, or the right or ability to perform work on the Ying property that are known at this time.

History

Silver-lead-zinc mineralization in the Ying district has been known and intermittently mined for several hundred years. The first systematic geological prospecting and exploration was initiated in 1956 by the Chinese government. Detailed summaries of the district's historical activities from 1956 to 2004, when Silvercorp first acquired interests in the area, are described in previous NI 43-101 Technical Reports.

Silvercorp acquired an interest in the SGX Mine Project in 2004. Subsequently, Silvercorp acquired the HZG, HPG, TLP, and LM mines (LME and LMW), all of which were previously held and operated by private Chinese companies.

Geological Setting, Mineralization and Deposit Types

The Property is situated in the 300 km-long west-northwest trending Qinling orogenic belt, a major structural belt formed by the collision of two large continental tectonic plates in Paleozoic time.

The northern continental plate, the North China Plate, covers all of Henan Province and most parts of North China, while the southern plate, the Yangtze Plate, covers most part of South China. Rocks along the orogenic belt between the two major tectonic plates are severely folded and faulted, offering optimal structural conditions for the emplacement of a myriad of mineral deposits. Several operating silver-lead-zinc mines, including those in the Ying Property, occur along this belt.

The Qinling orogenic belt is comprised largely of Proterozoic- to Paleozoic-age rock sequences consisting of mafic to felsic volcanic rocks with variable amounts of interbedded clastic and carbonate sedimentary rocks. The rocks are weakly metamorphosed to lower greenschist facies, with local areas of strongly metamorphosed lower amphibolite facies. The basement of the belt is comprised of highly metamorphosed Archean-age rocks of the North China plate, dominantly felsic to mafic gneisses with minor amphibolites, intrusive gabbros and diabases. The metamorphosed Qinling belt sequence and the underlying Archean basement rocks are intruded by mafic to felsic dikes and stocks of Proterozoic and Mesozoic ages. They are overlain by non-metamorphosed sedimentary rock sequences of Mesozoic to Cenozoic age, primarily marls and carbonaceous argillites, which are in turn overlain locally by sandstone-conglomerate sequences.

The dominant structures in the Qinling orogenic belt are west-northwest trending folds and faults generated during the collision of the two major tectonic plates in Paleozoic time. The faults consist of numerous thrusts having a component of oblique movement with sets of conjugate shear structures trending either northwest or north-east. These conjugate shear zones, which display features of brittle fracturing such as fault gouge, brecciation and well-defined slickensides, are associated with all the important mineralization recognized along the 300 km-long orogenic belt.

The Ying Property contains multiple mesothermal silver-lead-zinc-rich quartz-carbonate veins in steeply-dipping fault-fissure zones which cut Archean gneiss and greenstone. To date, significant mineralization has been defined or developed in at least 308 discrete vein structures, and many other smaller veins have been found but not as yet well explored.

Structurally, the vein systems throughout the district are all somewhat similar in that they occur as sets of veins of generally similar orientation enclosed by fault-fissure zones which trend most commonly northeast-southwest, less commonly north-south, and rarely northwest-southeast. The structures extend for hundreds to a few thousand metres along strike. They are often filled by altered andesite or diabase dikes together with quartz-carbonate veins or as discrete zones of altered bedrock (mainly gneiss) associated with local selvages of quartz-carbonate veinlets. From one-third to one-half of the structures exposed at the surface are conspicuously mineralized as well as altered.

The vein systems consist of narrow, tabular or splayed veins, often occurring as sets of parallel and offset veins. The veins thin and thicken abruptly along the structures in classic 'pinch-and-swell' fashion with

37

widths varying from a few centimetres up to a few metres. 'Swells' formed in structural dilatant zones along the veins often forming mineralized 'shoots'. At the SGX mine, these shoots range from 30 m to more than 60 m in vertical and horizontal dimensions over true vein widths of 0.4 m to 3.0 m. The vertical dimension of the SGX shoots is commonly twice or more the horizontal dimension. Longitudinal sections constructed along the veins indicate that many of the shoots have a steep, non-vertical rake.

The vein systems of the various mine areas in the district are also generally similar in mineralogy, with slight differences between some of the separate mine areas and between the different vein systems within each area. These differences have been attributed to district-scale mineral zonation at different levels of exposure. This subtle zonation is thought to be perhaps analogous to the broad scale zonation patterns observed in the Coeur d'Alene District (USA) and characteristic of many other significant mesothermal silver-lead-zinc camps in the world (Broili et al. 2008, Broili et al. 2010).

Exploration

From 1 July 2016 to 31 December 2019 (the reporting period), Silvercorp conducted extensive exploration programs on the Ying property that included exploration-development activities in the SGX mine area, including two producing mines (SGX and HZG), the HPG mine area, the TLP and LM mine areas, including three producing mines (TLP, LME, and LMW), and the DCG project. The past exploration activities, including surface activities, have been detailed in previous Technical Reports prepared for the Ying Property.

Other than drilling, the projects have been explored primarily by underground development and sampling. The workings follow the vein structures along strike, on levels spaced approximately 40 m apart. Silvercorp has found this method of underground exploration an effective and efficient way to define the geometry of the mineralized structures, in part due to the discontinuous character of the high grade mineralization, but also to the relatively inexpensive development costs.

Channel samples across the mineralized structures are collected across the back of drift tunnels and the walls of crosscut tunnels at 5 m intervals, with the spacing of channel samples increasing to 15 or 25 m in the non mineralized sections of the vein structures. Individual channels can consist of multiple chip samples, cut across and bracketing the mineralization and including associated wall rocks across the tunnel. Assay results of samples are documented on underground level maps and longitudinal sections.

The exploration tunneling and drilling programs were conducted during the reporting period to upgrade the Indicated and Inferred Mineral Resources, to test the down-dip and along-strike extensions of the major mineralized vein structures and their parallel subzones, and to explore new target areas. The programs comprised 201,688 m of tunneling, including 120,801 m of drifting along mineralized structures and 52,712 m of cross cutting across mineralized structures. Drift and crosscut tunnels have been developed at 30 m to 50 m intervals vertically to delineate higher category Mineral Resources. A total of 75,334 channel / chip samples was collected from the six mine areas.

Drilling

Prior to Silvercorp obtaining the rights to the SGX mine in 2004, there was little drilling work completed on the Ying Property. Drilling programs conducted by previous operators include a 10,736 m surface drilling program in the TLP-LM area by the No. 6 Nonferrous Geological Exploration Team from 1991 to 1994 and a test drilling program of two holes in the SGX area by the Henan Nonferrous Geological Exploration Bureau in 2003.

Since acquiring the Ying projects, Silvercorp has initiated systematic drilling programs to test the strike and down-dip extensions of the major mineralized vein structures and explore for new mineralized structures in less-explored or unexplored areas in the Property.

38

Since 2004, Silvercorp has organized extensive underground diamond drilling programs each year in the Ying Mining District with a total accumulated metreage of 1,082,840 m completed as of June 2016.

Drilling programs were continuously conducted over the Property from July 2016 to December 2019 (the Reporting Period). Underground and surface drilling were carried out in mining areas to test the down-dip extension of major mineralized vein structures, extend the Indicated and Measured Mineral Resources at or above the current mining depth, and infill the Inferred Mineral Resource blocks defined in previous drilling programs below the current mining depth. Most of the holes were designed as inclined holes to test multiple vein structures and to ensure a good intersection angle. A total of 325,151 m in 1,090 diamond holes was completed, including 13,236 m in 38 surface holes and 311,915 m in 1,052 underground holes drilled from at or above the current mining elevations. Results of the diamond drilling program were the down-dip and strike extension of most of the major mineralized veins and the discovery of a number of new mineralized veins in the current mine areas.

Drilling results from the 2016 - 2019 drilling program in the Property are briefly summarized in Table 2. These results have been incorporated into the mine databases and contribute to the current Mineral Resource update for the seven deposits. There is no drilling for DCG during this period.

Sampling and Analysis, and Data Verification

The numerous fault-fissure structures that cut the gneissic bedrock of the Ying Property are not continuously mineralized. Veins occur intermittently along these structures, appearing and disappearing along-strike and down-dip. Silvercorp's exploration consists of horizontal tunneling along and across the veins, in addition to driving raises or declines to access the veins at other levels. Core drilling is designed to intersect the veins in other locations both laterally and vertically. Channel samples are collected from underground tunnels and other workings, and core samples are collected from altered and mineralized drill cores. The sample collection and preparation follow accepted industry practice.

Core Samples

NQ-sized drill cores (48 mm in diameter) are recovered from the mineralized zones. Drill core is logged, photographed and sampled in detail at the surface core shack, with each mine having its own logging and core-cutting facilities. Samples are delineated by lithology, mineralization, and alteration. Mineralized zones are sampled together with wallrock samples that bracket the mineralization. Samples have a minimum length of 20 cm and a maximum length of 2 m.

Chip / Channel Samples

Channel samples lines are marked by a geologist and collected as continuous chip samples from the roofs of drift tunnels (perpendicular to the mineralized vein structure), and from the walls of crosscut tunnels (which cross the mineralized vein structure). Samples have a minimum size of 20 cm and a maximum size of 2 m. Drill and channel samples are numbered following protocols outlined by Silvercorp that generates unique IDs. Samples bracket the vein in addition to sampling the vein itself.

39

Sampling, Analysis and Data Verification

Drill core samples are stored in securely sealed bags at the core logging facilities until shipment by courier to one of the following three reputable commercial laboratories which are chosen based on capacity:

• The Analytical Laboratory of Henan Nonferrous Exploration Institute (Zhengzhou Nonferrous Laboratory) in Zhengzhou, Henan Province.

• The Chengde Huakan 514 Geology and Mineral Testing and Research Institute (Chengde Laboratory) in Chengde, Hebei Province.

• The Analytical Laboratory of the Inner Mongolia Geological Exploration Bureau (Inner Mongolia Laboratory) in Hohhot, Inner Mongolia.

The three external laboratories are accredited and certified as first-class laboratories by the Chinese government. The procedures for sample preparation and quality management in these laboratories are established in accordance with the official Chinese technical standard DZ/T 0130-2006 (The Specification of Testing Quality Management for Geological Laboratories), which is a combination of the basic principles and methodologies of ISO 9000:2000 and ISO/IEC 17025:1999.

Channel samples are analyzed on site at the Ying assay laboratory located at the mill complex in Luoning County. A brief examination of the Ying Laboratory was made by the QPs in both 2013 and 2016, as outlined in previous Technical Reports. The assay laboratory is officially accredited by the Quality and Technology Monitoring Bureau of Henan Province and has been used to analyze both channel samples taken from underground workings for Resource estimation purposes, and concentrate produced from the processing plants. Most of the processes for the analysis of channel samples and concentrate are completed within separate buildings, rooms, and instruments.

Silvercorp has established QA/QC procedures which cover the sample collection and processing at the Ying Property. All drilling and channel sampling programs completed on the Property incorporate the insertions of Certified Reference Materials (CRMs) and blanks into the sample stream on a batch by batch basis. Duplicate field samples are also included in the drilling programs.

Silvercorp's QA/QC programs and results prior to July 2016 have been described in previous Technical Reports. The following discussion is based on the QP's independent review of the drilling and channel sampling QA/QC databases associated with the July 2016 to December 2019 programs, which comprises 1,088 drillholes and 75,334 channel samples.

Silvercorp monitors silver, lead, zinc, copper, and gold in drillhole sampling, and silver, lead, and zinc in channel sampling programs. This is accomplished through the insertion of CRMs, blanks, and field duplicate samples. In this report gold and copper values are not discussed in detail as they are not material components of the Mineral Resource.

A summary of QA/QC samples included in the July 2016 - 2019 program is presented in Table 3. Table 4 summarizes the insertion rate of these QA/QC samples.

Mineral Processing and Metallurgical Testing

The lab scale mineral processing and metallurgical tests for the Ying Property deposits were done by three laboratories in China:

• Hunan Nonferrous Metal Research Institute (HNMRI) using SGX mineralization in 2005.

• Tongling Nonferrous Metals Design Institute (TNMDI) using HZG mineralization in 2006.

• Changsha Design and Research Institute (CDRI) using TLP mineralization in 1994.

The objectives of the lab mineral processing testwork were:

• To maximize silver recovery to the lead concentrate.

• To develop a process flow sheet with appropriate operating parameters as a basis for the industrial scale implementation of lead, zinc, and silver recovery.

• To determine the product quality characteristics relative to the relevant national standards.

The metallurgical testing consisted of mineralogical assessment, flotation tests, and specific gravity measurements of the mineralized veins.

SGX is the main deposit and the HNMRI work is the most comprehensive; therefore, the lab test results from HNMRI's study (2005) on SGX mineralization were used for both mill Plant 1 (2005) and Plant 2 (2008) design.

AMC is not aware of any subsequent external Design Institute metallurgical testwork having been carried out, although continual on-site 'plant-tuning' occurs.

Mineral Resource and Mineral Reserve Estimates

The Mineral Resource estimates for the SGX, HPG, LMW, and LME deposits were carried out by independent QP Rod Webster, MAIG of AMC who takes responsibility for these estimates.

The Mineral Resource estimates for the TLP, HZG, and DCG deposits were carried out by independent QP Simeon Robinson, P.Geo. of AMC who takes responsibility for these estimates.

The December 2019 Mineral Resources were estimated using a block modelling approach and the dynamic anisotropy application within Datamine™ software. Except for DCG, all metal grades were estimated using ordinary kriging. At DCG metal grades were estimated using inverse distance squared (ID²).

The Mineral Resources include material (approximately 30% of the total Mineral Resources) below the lower elevation limit of Silvercorp's current mining licenses. However, because of the nature of Chinese regulations governing applications for new or extended mining licenses, the QPs for the Mineral resource

41

estimation are satisfied that there is no material risk of Silvercorp not being granted approval to extend the lower depth limit of its licenses to develop these Mineral Resources as and when required.

Table 5 shows the Mineral Resources and metal content by mine for the Property as of 31 December 2019. The Mineral Resources are reported above a COG based on in-situ values in silver equivalent (AgEq) terms in grams per tonne. COGs incorporate mining, processing and G&A costs provided by Silvercorp for each mine and reviewed by the QP for Mineral Reserves - see Table 6. The AgEq formula and cut-off grade for each mine are shown in the footnotes of Table 5.

Comparison of Mineral Resources, 30 June 2016 and 31 December 2019

A comparison of Mineral Resource estimates between 30 June 2016 and 31 December 2019 indicates the following:

• Measured plus Indicated tonnes have increased by 23% overall, while the Inferred tonnes have increased by 78%.

• Measured plus Indicated grades have decreased overall by between -2% and -6%. Inferred grades decreased between -20% and -26% overall (both comparisons excluding gold as it is a very minor contributor).

• The net result in the Measured plus Indicated categories has been an increase in the contained silver of 18% and an increase in the contained lead metal of 16%. The increase in zinc content was 20%.

• The net result in the Inferred category has been an increase in the contained silver metal of 42% and a significant increase in both the contained lead and zinc metal, with increases of 38% and 32% respectively.

Reasons for the differences in grade, tonnes, and contained metal include Mineral Resource additions and conversion to higher categories arising from drilling and level development, different COGs and depletion due to mining. Additional channel and drillhole samples also became available between the two estimates to extend the Mineral Resources along-strike and down-dip, and allowed changed interpretation of the veins, given the greater degree of geological understanding.

Mineral Reserve Estimate

The Mineral Reserve estimates for the Property were prepared by Silvercorp under the guidance of independent Qualified Person, Mr. H. A. Smith, P.Eng., who takes QP responsibility for those estimates.

The Mineral Reserve estimation is based on the assumption that current stoping practices will continue to be predominant at the Ying property, namely cut and fill resuing and shrinkage stoping, using hand-held drills (jacklegs) and hand-mucking within stopes, and loading to mine cars by rocker-shovel or by hand. The largely sub-vertical veins, generally competent ground, reasonably regular vein width, and hand-mining techniques using short rounds, allows a significant degree of selectivity and control in the stoping process. Minimum mining widths of 0.5 m for resuing and 1.0 m for shrinkage are assumed. The QP has observed the mining methods at the Ying property and considers the minimum extraction and mining width assumptions to be reasonable. Minimum dilution assumptions are 0.10 m of total overbreak for a resuing cut and 0.2 m of total overbreak for a shrinkage stope.

For the total tonnage estimated as Ying Mineral Reserves, 49.7% is associated with resuing and 50.3% with shrinkage.

Cut-off Grades

Mineral Reserves have been estimated using breakeven cut-off values for shrinkage and resuing at each site as appropriate. The cut-off grade basis is summarized below and in Table 6.

COG AgEq (g/t) = (operating cost + sustaining capital + mineral resources tax) / (Ag price x processing recovery x payable).

43

In determining metal prices for use in the cut-off calculations, available consensus forecast information, prices used in recent NI 43-101 reports, three-year trailing averages, and prices current as of March 2020 were referenced. The exchange rate used in the cut-off calculations was arrived at in similar fashion.

Note: Costs, recoveries, payables, and metal price assumptions as per Table 6 above.

Dilution

Minimum mining widths are assumed as 0.5 m and 1.0 m, respectively, for resuing and shrinkage. For resuing, a dilution factor has been applied to each true vein width up to a minimum extraction width of 0.5 m or to (vein width plus 0.1 m) where the true width is greater than 0.4 m. For shrinkage, a minimum dilution factor of 0.2 m is added to the minimum vein width of 0.8 m. The QP notes that a key strategy used at Ying for minimizing floor dilution is the placement of rubber mats and / or conveyor belting over the waste fill floor in resuing stopes immediately before each resuing blast. This effectively serves as a barrier between ore and waste.

The dilution calculation process used for the Mineral Reserves estimation assumes that the resulting figures represent the overall tonnes and grade delivered to surface. There is a small degree of waste hand-sorting, and therefore upgrading, that occurs underground, depending on the mine and mining method. The QP considers that the resulting impact of this hand-sorting on the delivered product is not significant enough to materially affect the dilution factors used in the estimation.

The QP notes that the projections for dilution in both resuing and shrinkage stopes assume a high degree of process control in terms of design, drilling, and blasting, and that such control on an ongoing basis is critical to achieving dilution targets.

Table 8 summarizes average dilution from the Mineral Reserve calculations for each of the Ying mines. The QP considers that the current dilution estimation is reasonable considering the enhanced focus on mining process control in recent years and the observed results from those efforts.

Mine	Dilution %

HZG	18	20
HPG	18	19
LME	16	17
TLP	14	18
LMW	13	14
Total Ying	15	18

Mining Recovery Factors

Mining recovery estimates used in the Mineral Reserve calculations are based on experience at each of the Ying operations and for each mining method. For resuing stopes, 95% total recovery is assumed; for shrinkage stopes, 92% total recovery is assumed. Minimal pillars are anticipated to remain between adjacent mining blocks in the same vein, and partial recovery in sill pillars is allowed for in the respective recovery factors.

Mineral Reserve Estimate

To convert Mineral Resources to Mineral Reserves, Silvercorp uses the following procedures:

46

• Selection of Measured and Indicated Resource areas (potential stope blocks) for which the average AgEq grade is greater than the mine cut-off AgEq grade.

• Application of minimum extraction and mining width criteria and calculation of dilution at zero grade.

• Estimation of Mineral Reserve potential by applying relevant mining loss factors.

• Reconfirmation that diluted AgEq grade is greater than mine cut-off.

• Confirmation as Mineral Reserves by considering any other significant cost factors such as additional waste development required to gain access to the block in question.

Table 9 summarizes the Mineral Reserve estimates for each Ying mine and for the entire Ying operation.

44.1% of the Mineral Reserve tonnage is categorized as Proven and 55.9% is categorized as Probable.

The QP notes that for TLP and LMW, silver and lead Mineral Reserve grades are approximately the same as the average silver and lead mined grades over the FY2017 to FY2020 timeframe. For the combined SGX, HZG, HPG, and LME mines, average silver and lead Mineral Reserve grades show an approximately 25% reduction compared to the average silver and lead mined grades over the FY2017 to FY2020 period, whereas average zinc Mineral Reserve grades show an approximately 25% increase. This is consistent with the mining plan generally moving to depth in these mining areas as the life-of-mine (LOM) progresses. The QP also notes that the grade distribution of the Mineral Reserves and a continued focus on best mining practices and minimizing dilution provide a continuing opportunity to mine at above-overall-average grades in at least the early stages of the projected remaining LOM.

Table 10 below summarizes the total tonnage mined and total metals produced from the Ying Projects as a whole between December 31, 2019, the date of the latest Mineral Reserve report, and March 31, 2021:

Mineral Reserves Sensitivity to Cut-off Grade

The sensitivity of the Ying Mineral Reserves to variation in COG has been tested by applying a 20% increase in COG to Mineral Reserves at each of the Ying mines. The approximate percentage differences in contained AgEq ounces for each of the Ying mines and for the property as a whole are shown in Table 11:

Mine AgEq oz reduction	4.7%	12.0%	21.0%	9.4%	14.1%	11.4%
Ying total AgEq oz reduction	8.8%

The lowest sensitivities are seen at SGX and LME with, respectively, estimated 4.7% and 9.4% reductions in contained AgEq ounces when the COG is increased by 20%. The highest reduction of 21.0% is noted at HPG. For Ying as a whole, an approximately 8.8% reduction in AgEq ounces demonstrates relatively low overall COG sensitivity.

1 DCG Project Measured and Indicated Resources included.

For the Property as a whole, total Mineral Reserve tonnes are approximately 60% of Mineral Resource (Measured plus Indicated) tonnes. Silver, lead, and zinc Mineral Reserve grades are 110%, 105%, and 110% respectively of the corresponding Measured plus Indicated Mineral Resource grades. Metal conversion percentages for silver, lead, and zinc are 65%, 62%, and 66% respectively.

With respect to the difference in tonnes and metal content between (Measured plus Indicated) Mineral Resources and (Proven plus Probable) Mineral Reserves, the QP makes note that: a) Mineral Resource COGs are approximately aligned with development ore cut-offs at each mine; and b) Mineral Resource areas that are not yet part of the LOM plan are not eligible for inclusion as Mineral Reserves.

Mining Operations

The Ying mine complex is a viable operation with a projected LOM through to 2040 based on Proven and Probable Reserves. The potential exists for an extended LOM via further exploration and development, particularly in areas of Inferred Resources.

Annual ore production is projected to be maintained between 655 kt and 687 kt through to and including FY2031. From FY2032 to FY2036, ore production is projected to average about 600 ktpa, and then to drop from 443 ktpa to 283 ktpa over the final four years, as operations at the SGX, HPG, LME, and LMW mines wind down. The QP notes that the development and infrastructure required to allow production as projected is either already in place, is in development, or has been planned. The ability to achieve projected production will, to a large degree, be dependent on diligent planning and the consistent availability of resources, particularly skilled manpower and, although there is a certain amount of risk associated with the provision of key resources, the Ying mines performance in recent years lends support to a having a good degree of confidence that production tonnage targets can be achieved.

Silver grades, particularly driven by SGX, are indicated to steadily decrease over the LOM. Through to and including 2025, the silver grade is projected to average 307 g/t. Beyond 2025, the silver grade ranges between 267 g/t and 203 g/t, but with the AgEq grade maintained in a fairly narrow range between 378 g/t and 436 g/t. The full LOM average AgEq grade is projected at 454 g/t. The grade profile is consistent with the mines developing more to depth, with a general decrease in Ag grades and a corresponding increase in Pb and Zn grades.

The Ying mines safety is governed by Chinese statutory requirements and the QP acknowledges that, in certain areas, those requirements are exceeded. The QP advises, however, that Silvercorp should continue with a focus on safety improvement, including implementation of a policy where the more stringent of either Chinese or Canadian safety standards are employed.

The generally good ground conditions, and the regularity and sub-vertical nature of the Ying district veins, could provide an opportunity to effectively employ more bulk-mining methods such as longhole benching, and still with reasonable dilution. The QP recognizes the technological change that would be required for their implementation but recommends that Silvercorp investigate the application of such methods.

Processing and Recovery Operations

Silvercorp runs two processing plants, Plants 1 and 2, at the Property, with a total current design capacity of about 2,800 tpd. The two plants are situated within 2 km of each other. Both were designed based on the lab tests completed by HNMRI in 2005. Plant 1 (Xiayu Plant - originally 600 tpd, upgraded to 800 tpd) has been in operation since March 2007. Plant 2 (Zhuangtou Plant) has been in production since December 2009, with an expansion from 1,000 tpd to 2,000 tpd completed in October 2011. Although current design processing capacity is about 2,800 tpd, it is understood that the actual capacity could reach 3,000 - 3,200 tpd. However, current LOM planning requires that the plants operate up to around 2,000 tpd.

The overall processes of the two plants are similar and comprise crushing, grinding, flotation of lead and zinc concentrates, and concentrate dewatering. Plant 1 currently produces only a lead / silver concentrate. In the LOM plan, the majority of ore tonnes will be processed through Plant 2, with Plant 1 being used as a backup to process low grade ore or development ore from LM, HZG, and part of TLP.

To optimize profitability, high grade lead concentrate from Plant 2 is blended with middle grade lead concentrate from Plant 1.

SGX / HPG ores also contain high-grade, large-size galena lumps with characteristic specular silver grey colour. These may be hand-sorted at the mine sites, crushed, and then shipped by dedicated trucks to Plant 1. The lumps can be milled in a dedicated facility, and then sold directly, or mixed with flotation lead concentrate for sale.

52

Both Plants 1 and 2 have exceeded target throughput levels. Lead and silver recovery targets are being met, although zinc recovery is lower than design, attributed to low zinc feed grades.

After innovation and modification to both plants over the last few years, lead and silver recoveries have increased significantly. Improvements have been consistently targeted on process system and other facilities both in Plant 1 and Plant 2 to improve the metal recovery and reduce energy consumption.

Historically, higher-grade feed from SGX has enhanced plant performance but, with the proportion of SGX ore decreasing, the challenge is to maintain similar metallurgical performance on lower grade feedstock. From recent performance, it appears that recoveries are being maintained but concentrate grades are lower than target, however, not to the extent where there is a major deterioration in smelter terms.

Infrastructure, Permitting and Compliance Activities

There are two tailings management facilities (TMF); TMF 1, adjacent to and serving Plant 1, and TMF 2, adjacent to and serving Plant 2. TMF 2 was completed in July 2012 and put into service in April 2013. The QP understands that site-specific risk assessment, such as for geotechnical risk, was originally carried out by Henan Luoyang Yuxi Hydrological & Geological Reconnaissance Company, with more recent assessments done by other organizations.

The TMFs were designed based on then current Mineral Resource / Mineral Reserve estimations and LOM production projections. Subsequent resource expansion and increased production projections indicate that the current tailings capacity will not be adequate for the full Ying LOM. Additional tailings capacity will thus be required in the later period of the LOM production. There are several location options for the third TMF, with assessment of those options still in the study stage. It is expected that there will be no problem to get permission to build the third TMF once it becomes necessary.

Reclaimed water from the tailings storage ponds and overflows from the two concentrators is recycled to minimize fresh water requirements. Zero discharge of the process water has been achieved at both TMFs in no-rainfall seasons.

Each mine in the Ying Property has a number of rock waste dumps. Waste dump capacity at all mines is enough for the anticipated LOM waste rock. Silvercorp is investing approximately $2.9 million (M) to construct a 1 Mtpa aggregate plant to recycle and crush the waste rock from the Ying Mining District, and then supply it to the local construction market. The plant is expected to be commissioned in October 2020, and its profit, after capital recovery, will be shared between the local government, the local communities, and employees.

Power for the Ying Property is drawn from Chinese National Grids with high-voltage lines to the different mine camps and mill plants. At SGX, one 35 kV overhead line supplies main power for all production, and two 10 kV lines act mainly as a standby source of power in case of disruption. In addition, two 1,500 kW and one 1,200 kW diesel generators installed at one of the substations act as back-up power supply in the event of a grid power outage.

Access to the SGX / HZG mine from Silvercorp's mill office complex is via a 7 km paved road to the Hedong wharf of the Guxian Reservoir, and then across the reservoir by boat to the mine site. Two large barges carry up to five 45 t ore trucks from the SGX / HZG and HPG mines to the plants. The HPG mine can be accessed either by boat or 12 km paved road, south-west of the main office complex. Ore from the TLP and LM mines is hauled to the Silvercorp central mill using 30 and 45 t truck fleets. The TLP, LME, and LMW mines are 15 km south-east of the main office complex and are accessed by paved road along the Chongyang River.

Silvercorp has all the required permits for its operations on the Property. The existing mining permits cover all the active mining areas and, in conjunction with safety and environmental certificates, give Silvercorp the right to carry out full mining and mineral processing operations. Six safety certificates have been issued

53

by the Department of Safety Production and Inspection of Henan Province, covering the SGX mine, Zhuangtou TMF, Shiwagou TMF, HPG mine, TLP mine, LMW mine, and LME mine. Five environmental certificates have been issued by the Department of Environmental Protection of Henan Province, covering the Yuelianggou project (SGX mine and 1,000 tpd mill plant), HPG mine, TLP mine, LMW mine, LME mine, and the 2,000 tpd mill plant built in 2009. For each of these certificates, there are related mine development / utilization and soil / water conservation programs, and rehabilitation plan reports. Silvercorp has also obtained approvals and certificates for wastewater discharge locations at the SGX mine, the HPG mine, and the two TMFs. All certificates must be renewed periodically.

There are no cultural minority groups within the area surrounding the general project. The culture of the broader Luoning County is predominantly Han Chinese. No records of cultural heritage sites exist within or near the SGX, HZG, TLP, LME, LMW, and HPG project areas. The surrounding land near the SGX Mining Area is used predominantly for agriculture. The mining area does not cover any natural conservation, ecological forests or strict land control zones. Current area vegetation is mainly secondary, including farm plantings. Larger wild mammals have not been found in the region. Small birds nesting and moving in the woodland are observed occasionally. The surrounding villagers raise domestic animals, such as chickens, ducks, pigs, sheep, and goats.

Capital and Operating Costs

Summary of Capital Costs

The main capital requirement at the Property is for mine development. Provision is also made for exploration drilling and for sustaining surface facilities, plant expenditure, personal protective equipment, and equipment in general. Specific processing plant capital requirements are projected to be minimal as plant capacity has previously been expanded to meet the forecast mine production.

Projected LOM capital costs, by mine and for Ying as a whole, are summarized in Table 14. An exchange rate of US$1 = 6.90 RMB is assumed.

Summary of Operating Costs

Major operating cost categories are mining, shipping, milling, G&A, product selling, Mineral Resources tax, and government fees and other taxes. Silvercorp utilizes contract labour for mining on a rate per tonne or a rate per metre basis. The contract includes all labour, all fixed and mobile equipment, materials, and consumables, including fuel and explosives, which are purchased through the company. Ground support consumables such as timber and power to the portal areas are the responsibility of the company. Shipping costs are for moving ore from each mine to the processing plant. Principal components of the milling costs are utilities (power and water), consumables (grinding steel and reagents) and labour, each approximately one third of the total cost. G&A costs include an allowance for tailings dam and other environmental costs. The major capital expenditure on the two tailings storage facilities has already been expended and ongoing costs associated with progressively raising the dam are regarded as an operating cost. The provision for Mineral Resources tax is approximately 3% of sales. Table 15 summarizes projected LOM operating costs, by mine, and for Ying as a whole. An exchange rate of US$1 = 6.90 RMB is assumed.

Smelter Contracts

Monthly sales contracts are in place for the lead concentrates with leading smelters, mostly located in Henan province. Among them are Henan Yuguang Gold and Lead Smelting Co. Ltd, JiyuanWanyang Smelting (Group) Co. Ltd, JiyuanJinli Smelting (Group) Co, Lingbao Xinling Smelting Co. Ltd, and Anyang Minshan Smelting Co. Ltd. For the zinc concentrate, sales contracts are in place with Henan Yuguang Zinc Industry Co. Ltd.

All contracts have freight and related expenses to be paid by the smelter customers.

The key elements of the smelter contracts are subject to change based on market conditions when the contracts are renewed each month. Table 16 shows terms most commonly applied.

Table 16	Key elements of smelter contracts

		1,500-2,000	88.5	1-2	80
		1,000-1,500	88
		500-1,000	87.5

With respect to lead and zinc terms, the above deductibles calculate out to 85 - 90% payable for the lead concentrate and approximately 70% for zinc, at long-term prices. These are in alignment with global smelter industry norms. Silver payables of approximately 90% are similarly in accord with industry norms.

Economic analysis

Although Silvercorp is a producing issuer and, therefore, does not require an economic analysis of the Ying Property for the purposes of this report, the QPs consider it reasonable to include a summary-level analysis to illustrate the potential economic impact relative to the latest Mineral Reserve estimations and to the associated production schedules.

The following metal prices, costs and exchange rate were used for the economic analysis:

•	Gold price	US$1,400/oz
•	Silver price	US$20/oz
•	Lead price	US$0.95/lb

58

•	Zinc price	US$1.10/lb
•	Mining cost	US$61.34/t
•	Milling cost	US$10.23/t
•	Shipping	US$3.92/t
•	Mineral Resources tax	US$6.86/t
•	G&A	US$8.30/t
•	Government fees and other taxes	US$2.78/t
•	Sustaining and growth capital	US$16.95/t
•	Exchange rate	US$1 = 6.90RMB

Based on the LOM production forecast through to 2040 and the metal price and other assumptions shown above, a base case pre-tax NPV of $954M at 5% discount rate is projected ($713M post tax). Over the LOM, 62% of the net revenue is projected to come from silver, 29% from lead, 6% from zinc, and 2% from gold.

A simple economic sensitivity exercise, assessing a +/- 30% change in individual metal prices, operating cost or capital cost, has indicated that most sensitivity is seen in silver price (similar variation in silver grade would effectively give the same result). The NPV is moderately sensitive to lead price and operating cost, and only slightly sensitive to zinc price and capital cost.

Annual Production Schedule

The LOM ore production schedule by mine is shown in Table 17.

Exploration and Development

The Ying Report includes a recommendation to continue exploration tunneling and diamond drilling at the Ying Property. The exploration tunneling is used to upgrade the drill-defined Resources to the Measured category, and the diamond drilling is used to expand and upgrade the previous drill-defined Resources, explore for new mineralized zones within the unexplored portions of vein structures, and test for the down-dip and along-strike extensions of the vein structures. The proposed exploration work is as follows:

5.2	GC Mine

Current Technical Report

Except as otherwise stated, the information in this section is based on the technical report titled 'NI 43-101 Technical Report Update on the Gaocheng Ag-Zn-Pb Project in Guangdong Province, People's Republic of China' (the 'GC Report') effective June 30, 2019 prepared by AMC Mining Consultants (Canada) Ltd. with authors Dinara Nussipakynova, P.Geo., Herbert A. Smith, P.Eng., Alan Riles, MAIG, and Patrick R. Stephenson, P.Geo. Two of the authors, Ms Nussipakynova and Mr Smith, visited the GC property in January 2018. All authors of the GC Report qualify as Independent Qualified Persons.

The following is a summary from the GC Report and is based on the assumptions, qualifications and procedures which are not fully described herein. The full text of the GC Report which is available for review on SEDAR at www.sedar.com is incorporated by reference in this AIF.

Project Description, Location and Access

The GC property is located in the vicinity of Gaocheng village, Gaocun Township, Yun'an District, Yunfu City, Guangdong Province, People's Republic of China. The Property is located west of the metropolitan city of Guangzhou, the capital of Guangdong Province. Guangzhou is located about 120 kilometres (km) north-west of Hong Kong and has a total population of almost 14 million residents, as of December 2016. 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.

62

Silvercorp owns 99% of the GC Mine through its 100% ownership of the shares of Yangtze Mining Ltd. (Yangtze Mining), which in turn wholly owns Yangtze Mining (H.K.) Ltd. (Yangtze Mining H.K.), and Fortune Gold Mining Limited, which in turn wholly owns Silvercorp Metals (China) Inc. Guangdong Found Mining Co. Ltd. (China), (Guangdong Found), is the designated joint venture operating company of the GC Mine. Yangtze Mining (H.K.) Ltd., a wholly owned subsidiary of Yangtze Mining, owns 95% of Guangdong Found. Silvercorp Metals (China) Inc. owns 4% of Guangdong Found. Guangdong Found has a 100% beneficial interest in the GC Mine. The boundaries of the mining permit were surveyed, and the boundary markers were staked in the ground by the Bureau of Land and Resources of Guangdong Province before issuing the mining permit to Guangdong Found in 2010.

The Mining Permit in the name of Guangdong Found is valid for 30 years to 24 November 2040, covers the entire 5.5238 km² area of the GC Mine and permits mining from 315 metres (m) to minus 530 m elevations. The permit allows for the operation of an underground mine to produce silver, lead and zinc.

Currently, GC Mine is subject to Mineral Resources taxes, levied at 3% of sales. This tax together with other government fees totals around 5% of net revenue. AMC is not aware of any additional royalties, back-in rights, payments, agreements, environmental liabilities, or encumbrances particular to the property other than those stated above.

History

Various state-sponsored Chinese Geological Brigades and companies have conducted geological and exploration work in the project area with systematic regional geological surveys commencing in 1959. Historical drilling commenced in 2001.

Prior to Yangtze Mining acquiring the GC Property in 2005, 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. It is reported that a total of 1,398 m of excavation comprised of 10 adits and tunnels had been completed on the property through the illegal activity.

A total of 43 diamond drillholes for a combined total of 13,463.74 m was drilled on the GC property between 2001 and 2007 prior to the property acquisition by Silvercorp. Diamond drillholes were drilled using PQ size in overburden, then reduced to HQ size for up to 100 m depth.

The Guangdong Provincial Institute of Geological Survey (GIGS) prepared a resource estimate for nine mineralized veins for the GC project after the 2004 - 2005 exploration season. This was not compliant with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards and is not material to the 2019 Technical Report.

Prior to this current report, four resource estimates for the GC project have been reported since 2008:

• Technical Report by SRK Consulting (SRK), dated April 2008 (entitled 'Technical Report on Gaocheng Ag-Zn-Pb Project and Shimentou Au-Ag-Zn-Pb Project, Guangdong Province, People's Republic of China').

• AMC Technical Report (entitled 'NI 43-101 Technical Report Update on the GC Ag-Zn-Pb Project in Guangdong Province, People's Republic of China'), effective date 18 June 2009.

• AMC Technical Report (entitled 'NI 43-101 Technical Report on the GC Ag-Zn-Pb Project in Guangdong Province, People's Republic of China'), effective date 31 December 2011.

• AMC Technical Report (entitled 'NI 43-101 Technical Report Update on the Gaocheng Ag-Zn-Pb Project in Guangdong Province, People's Republic of China'), effective date 30 June 2018.

Geological Setting, Mineralization, and Deposit Types

The GC Project is located at the intersection between the Wuchuan-Sihui Deep Fault zone and Daganshan Arc-ring structural zone. It is situated in the south-west part of the Daganshan uplift. Structures developed in the area are mainly the NWW-EW striking Gaocheng Fault zone, the NE striking Baimei Fault zone, and the Songgui Fault zone.

Basement rocks within the GC Project area encompass quartz sandstone, meta-carbonaceous siltstone, carbonaceous phyllite, calcareous quartzite and argillaceous limestone of the Sinian Daganshan Formation; quartz sandstone and shale of the Triassic Xiaoyunwushan Formation, and sandy conglomerate and conglomerate of the Cretaceous Luoding Formation. These rocks are intruded by Palaeozoic gneissic, medium-grained biotite granite, and Mesozoic fine- to medium grained adamellite, brownish, fine grained, biotite mylonite, granite porphyry, quartz porphyry, diabase, and aplite. The Mesozoic intrusives intruded along the south and southwest contacts of the Palaeozoic granites. The majority of Ag-Zn-Pb mineralization is hosted by the Mesozoic granite. The granite dips south and strikes west northwest, parallel to the majority of mineralized veins on the GC property.

Ag-Zn-Pb mineralization at the GC deposit can be divided into two types: primary and oxidized. The primary mineralization is mainly composed of galena-sphalerite-silver minerals which occur sparsely, as disseminations, veinlets and lumps. Primary mineralization accounts for 95% of the entire mineral resource. Oxide mineralization occurs on and near the surface.

Mineralized veins in the GC area occur in relatively permeable fault-breccia zones. These zones are extensively oxidized from the surface to depths of about 40 m. Veins in this zone exhibit open space and 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 mineral 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. Metallic minerals occur in narrow massive bands, veinlets or as disseminations in the gangue. Gangue minerals include chlorite, quartz, fluorite, feldspar, mica, hornblende, with a small amount or trace amount of kaolinite, tremolite, actinolite, chalcedony, garnet, zoisite, apatite, and tourmaline.

Alteration minerals associated with the GC vein systems include quartz, sericite, pyrite, and chlorite, together with clay minerals and limonite. Silicification commonly occurs near the centre of the veins. Chlorite and sericite occur near and slightly beyond the vein margins.

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

The poly-metallic mineralization of the GC deposit belongs to the mesothermal vein infill style of deposit.

Exploration

Silvercorp has carried out surface and underground exploration activities since 2008.

Surface-based exploration occurred primarily during 2008, which included soil sampling, geological mapping and trenching. Following up on geochemical anomalies, Silvercorp conducted trenching and pitting programs that exposed the mineralized veins on the surface and at shallow depth. A total of seven pits and one trench were excavated by Silvercorp exposing three veins.

More than 52 km of underground tunnelling and sampling at the Property was carried out between 2012 and 2018. These programs comprised 33,297 m of drifting along mineralized structures, 10,147 m of

64

crosscutting across mineralized structures, and 8,833 m of raises. Drifts and crosscuts were developed at 40 m intervals vertically to increase geological confidence in the Mineral Resource.

A total of 6,314 channel / chip samples were collected from the mine areas during 2018, with samples being assayed for Ag, Pb, and Zn. Prior to 2018, 44,166 channel / chip samples had been collected.

Drilling

Silvercorp completed its first phase of diamond drilling on the GC property in 2008. Systematic drilling commenced on the property in 2011 and continued through into 2018. All Silvercorp drilling was completed as NQ-sized core. Drillhole collars were surveyed using a total station and downhole surveys were completed every 50 m downhole. Surface drillhole collars were cemented after completion and locations of drillholes were marked using 50 x 30 x 20 centimetres (cm) concrete blocks.

Core recoveries from Silvercorp drilling programs varied between 41.67% and 99.96% averaging 96.85%. AMC reviewed the relationship between grade and core recovery and found no bias.

All drill core is stored in a clean and well-maintained core shack in the GC camp complex. This core shack is locked when unattended and monitored by two security personnel 24 hours a day.

The majority of drillholes were drilled as inclined holes to test multiple vein structures. Underground drillholes were drilled as fans of multiple holes from single set-ups.

Sampling, Analysis and Data Verification

Drill core processing is completed by Guangdong Found employees in accordance with a standard procedure. Core recovery is measured followed by detailed logging of the core with lithological, vein and mineralization contacts identified and recorded. The core is photographed and sampled on 1.5 m maximum intervals and at geological or mineralization contacts. Core is cut in half with a rock saw with one half bagged and secured for shipment to the laboratory, and the other half retained in the core tray for future reference.

Channel samples are collected along sample lines perpendicular to the mineralized vein structure as well as from walls of cross-cut tunnels and bottom of trenches. Samples include vein material and associated wallrock.

Samples were shipped from Gaocheng site to an ALS Laboratory in Guangzhou between 2008 and 2014 and for part of 2018. Commencing in 2012 Silvercorp shipped samples to the Gaocheng onsite laboratory in addition to ALS. Gaocheng was the primary laboratory from 2014 to 2017. In 2018, ALS was the primary laboratory at the beginning of the year, but Silvercorp reverted to the Gaocheng lab later in the year. The Gaocheng onsite laboratory is owned and operated by Silvercorp. It is not certified by any standards association.

All data for the Gaocheng Project is stored within a central Microsoft Access Database, which is managed by two designated database administrators. Drillhole data is collected in Microsoft Excel and imported into the Access database. Underground mapping is recorded on grid paper and in Excel and then imported into Access or Micromine 3D software.

Silvercorp has routinely inserted Certified Reference Materials (CRMs) since 2011. Blank (uncrushed) samples and coarse duplicates have been inserted since 2012 (drilling) and 2014 (underground sampling). Umpire samples (pulp duplicates) have been sent to a different laboratory since 2011.

The CRM insertion rate for drillhole sample batches has been in the range of 3 - 4% in the last five years, and for underground chip sample batches has been in the range of 2 - 4%. AMC understands that CRM performance at Gaocheng has not, to date, been monitored on a batch by batch basis, and Silvercorp was unable to provide AMC with control charts compiled at the time of assaying. Subject to certain caveats, CRM results have generally confirmed the reasonable analytical accuracy of the laboratories used.

65

Data verification was carried out by the QP with 8% of the samples being verified in the database. Of the 14,023 samples contained within the vein domains, 1,151 samples were verified, 12 errors were found, and 18 assay certificates not located. The six errors noted out of 557 samples checked in 2018 represent error rate of 1%.

The QP has highlighted some issues for improvement in the Quality Assurance/Quality Control process and has provided a series of recommendations in that regard. The QP does not consider these issues to have a material impact on Mineral Resource estimates and considers the assay database to be acceptable for Mineral Resource estimation.

Mineral Processing and Metallurgical Testing

Since the metallurgical testing reported in the 2012 Technical Report, no further testing has been done. The mill functioned in a trial mode up to 2014 and, from that point (FY2015 starting Q2 2014), has been in commercial production.

Metallurgical testing for the GC project was carried out by the Hunan Research Institute of Non-Ferrous Metals and reported in May 2009 in the report 'Development and Research of the Comprehensive Recovery Test of Lead Zinc Silver Tin Sulphur for the Lead Zinc Ore Dressing in GC Mine Area'. This report was made available to AMC in English translation by Silvercorp. The testwork was also summarized in the January 2011 GMADI report as part of the 'Design Instructions' for the plant design.

The objectives of the testwork were, following on from previous testwork of 2007 on samples from artisanal mining dumps, to i) maximize silver recovery to the lead concentrate, ii) investigate the potential for tin recovery, iii) develop a process flow sheet with appropriate operating parameters as a basis for the industrial scale implementation of lead, zinc, sulphur (and possibly tin) recovery, and iv) determine the product quality characteristics relative to the relevant national standards.

Since the start of trial operations in 2013 and commercial production in 2014, lead and zinc concentrates have been produced in commercial quantities at the Gaocheng mill. The overall process consists of crushing, grinding, sequential flotation of lead, zinc and pyrite concentrates, and concentrate dewatering by disc filtration. An experimental tin recovery gravity separation circuit is installed on pyrite flotation tails.

Two-stage crushing is carried out, with the second stage in closed circuit. Run of mine ore at -350 mm is reduced to crusher product at -10 mm. This is followed by two-stage grinding in ball mills to a product size of 80% passing 75 µm (P80 of 75 µm).

The flotation process consists of a standard flotation of lead, with three-stage cleaning of the lead concentrate, then flotation of zinc concentrate with three-stage cleaning; leaving pyrite tailings as sulphur concentrate. Concentrates are dewatered by conventional thickening and filtration.

Trucks under escort by security personnel are used to transport lead and zinc concentrates from the mine site to refineries. A front-end loader is used to load the concentrate from storage sheds near filters at the mill site to the concentrate shipping trucks.

Since completion of commissioning, the plant has processed approximately the same amount of ore each year (approximately 260 ktpa).

There is a laboratory on site equipped with the customary sample preparation, wet chemistry, and basic photometric analytical equipment; as well as crushing, grinding, flotation, and gravity-separation metallurgical testing equipment.

Mineral Resource and Mineral Reserve Estimates

Mineral Resource Estimates

66

The Mineral Resources for the GC deposit have been prepared by Silvercorp. Ms. Dinara Nussipakynova, P.Geo., of AMC, has reviewed the methodologies and data used to prepare the Mineral Resource estimates and, after some adjustment to the Mineral Resource classification, is satisfied that they comply with reasonable industry practice. Ms. Nussipakynova takes responsibility for these estimates.

AMC is not aware of any known environmental, permitting, legal, title, taxation, socioeconomic, marketing, political, or other similar factors that could materially affect the stated Mineral Resource estimates.

The data used in the Mineral Resource estimation includes results of all drilling carried out on the Property to 31 December 2018. The estimation was carried out in Micromine™ software. Interpolation was carried out using inverse distance cubed (ID3) for all the veins.

Table 18	Summary of Mineral Resources as of 31 December 2018

Resource classification	Tonnes (kt)	Ag (g/t)	Pb (%)	Zn (%)	Contained metal

The GC deposit consists of 110 veins, each of which has a separate block model. Approximately 22,660 m of channel samples and 34,160 m of core samples from 1,311 drillholes form the basis of the estimate. Capping is employed on the raw data and the composite length equals the vein thickness.

The parent block size for all veins was 2 m by 2 m by 2 m (x, y, z) with sub-cells employed. The sub-celling resulted in minimum cell dimensions of 0.4 m by 0.4 m by 0.4 m (x, y, z). AMC imported all 110 block models into Datamine software. The volume comparison of the original models versus the Datamine models showed a difference of less than 1%.

Interpolation was carried out using the inverse distanced cubed (ID³) method. Mining depletion and write-offs based on survey information to 31 December 2018 were coded into the block models by Silvercorp.

Mineral Resources are classified as Measured, Indicated, and Inferred. AMC reviewed the classification of each vein and requested changes when the classification needed to be modified to form potentially mineable shapes.

The block models were validated by AMC in three ways. First, visual checks were carried out to ensure that the grades respected the raw assay data. Secondly, swath plots were reviewed. Thirdly, the estimate was statistically compared to the composited assay data, with satisfactory results.

The following observations have been made by the QP from a comparison of the 2018 Mineral Resource estimate and the 2019 Mineral Resource estimate:

• Measured and Indicated tonnes have increased by 42%. The Inferred resource decreased by 3%.

67

• In the Measured category silver grade decreased by 5% and lead and zinc grades increased by 3% and 4% respectively.

• In the Indicated category silver grades decreased by 16%, lead and zinc grades decreased by 16% and 6% respectively.

• In the Inferred category the grades decreased for silver, lead, and zinc by 15%, 13%, and 6% respectively.

• The net result in the Measured category has been a significant increase in contained metals: silver by 17% and lead and zinc by approximately 28% and 26% respectively.

• The net result in the Indicated category has been an increase in contained silver metal of 31%, with lead and zinc contained metals increased by 29% and 46% respectively.

• The net result in the Inferred category has been a decrease in contained silver of 18%, a lead metal decrease of 15% and a zinc metal decrease of 9%.

Reasons for the differences in grade, tonnes, and contained metal include:

• Updated interpretation of the veins.

• Discovery of new veins.

• Conversion of Inferred resources to a higher classification.

• Depletion through mining.

Mineral Reserve Estimates

To convert Mineral Resources to Mineral Reserves, mining cut-off grades have been applied, mining dilution has been added and mining recovery factors assessed on an individual vein mining block basis. Only Measured and Indicated Resources have been used for Mineral Reserves estimation.

The Mineral Reserve estimates for the Gaocheng property were prepared by Silvercorp under the guidance of independent Qualified Person, Mr. H. Smith, P.Eng., who takes QP responsibility for those estimates.

The Mineral Reserve estimation is based on the assumption that current stoping practices will continue at the Gaocheng property, namely predominantly shrinkage stoping but also with some cut and fill resuing. Minimum mining widths of 1.0 m for shrinkage and 0.5 m for resuing, and dilution of 0.20 m total for shrinkage and 0.10 m for resuing cut and fill stopes are assumed. Full breakeven cut-off grades used are 200 g/t AgEq for shrinkage and 245 g/t AgEq for resuing.

Table 19 summarizes the Mineral Reserves estimate for the Gaocheng mine. 49% of the Mineral Reserve tonnage is categorized as Proven and 51% is categorized as Probable.

Table 19	Gaocheng mine Mineral Reserves estimate at 31 December 2018

Reserve classification	Tonnes (kt)	Ag (g/t)	Pb (%)	Zn (%)	Contained metal
Ag (koz)	Pb (Mlbs)	Zn (Mlbs)
Proven	1,865	94	1.6	3.5	5,611	65	142
Probable	1,955	96	1.4	3.0	6,064	60	129
Proven and Probable	3,820	95	1.5	3.2	11,675	125	271

Notes to Mineral Reserve Statement:
• Full breakeven cut-off grades: Shrinkage = 200 g/t AgEq: Resuing = 245 g/t AgEq.
• Marginal material cut-off grade: Shrinkage = 160 g/t AgEq; Resuing = 205 g/t AgEq.

68

• Dilution (zero grade) assumed as a minimum of 0.1 m on each wall of a shrinkage stope and 0.05 m on each wall of a resuing stope.
• Mining recovery factors assumed as 95% for resuing and 92% for shrinkage.
• Metal prices: Silver US$18/troy oz, lead US$1.00/lb, zinc US$1.25/lb, with respective payables of 85%, 90%, and 70%.
• Processing recovery factors: Ag - 77%, Pb - 88%, Zn - 84%.
• Effective date 31 December 2018.
• Exchange rate assumed is RMB6.50:US$1.00.
• Rounding of some figures may lead to minor discrepancies in totals.

Since the start of mining operations through to the end of 2018, a total of 1,251,000 tonnes has been milled from pre-and post-commercial production mined at Gaocheng, with average head grades of 96 g/t silver, 1.5% lead, and 2.7% zinc. The comparison of the head grades to date with the current Mineral Reserve estimates shows a reduction in silver grade of 1%, a reduction in lead grade of 1%, and an increase in zinc grade of 18% in the Mineral Reserves.

A pillar is maintained around the Main Shaft. Development may occur within the pillar zone, however stope production will not be allowed. The shaft pillar is an expanding cone with a dip from the collar elevation of 80^o. The pillar radius at surface (248 mRL) is 13 m and the Main Shaft radius is 3 m.

Relative to the Mineral Reserve estimates in the previous Technical Report (2018 Technical Report), there is a 10% increase in Proven Mineral Reserve tonnes and a 4% increase in Probable Mineral Reserve tonnes, with an increase in Mineral Reserve total tonnes of 7% (256,000 t).

Mining Operations

Mining to date has been conducted in two stages. Stage 1 targeted bringing the project into production as soon as practicable using mobile, rubber-tired, diesel-powered equipment (development jumbo, loader and truck) with surface declines access down to -50 mRL. Stage 2 development from -50 mRL down to -300 mRL employs conventional tracked equipment (battery powered locomotives, rail cars, electric rocker shovels and pneumatic hand-held drills) via a surface shaft access. In-stope rock movement is by gravity to draw points or hand-carting to steel-lined passes.

The rock mass condition is categorized as Fair to Good and it is anticipated that the vein and host rocks in the mine area will continue to be largely competent and require minimal ground support other than in weaker ground areas.

Production Rate

The average production is approximately 65 tonnes per day per stope for shrinkage stopes and 15 tonnes per day per stope for resue stopes with production per level capped at approximately 25% of the available stopes and up to 30 stopes concurrently working over all active levels.

The actual production rate from each stope is dependent on the vein width, and as such, the production rate and schedule assume a balance of wider and narrower vein stopes (generally shrinkage and resue respectively).

Mining Methods

Shrinkage stoping and resue stoping are the methods employed.

To support AMC's understanding of the Silvercorp application of stoping methods and also their suitability for the GC Mine environment, AMC previously observed the application of these stoping methods at Silvercorp's Ying mine operation during May 2016. AMC visited the GC site in January 2018. The Ying mine is located in Luoning County, in the Henan Province, about 10 km south-east of Xiayu and about 60 km south-east of Luoning. AMC considers the methods employed to be appropriate for the GC Mine environment.

69

Mine Development

The mine design is now based on Mineral Resources above 100 g/t AgEq, with the addition of vein exploration development (which in some part, is also used for stope access). Vein exploration development is categorized as development that occurs outside of the Mineral Resource categorization. Vein exploration development is reported as development waste and, for planning purposes, is assigned zero grade irrespective of its actual resource grade.

The mine levels are located at 50 m vertical intervals. Levels are graded at 0.3% from either the Ramp or Main Shaft access, however the mine design provided does not incorporate this feature. AMC does not consider this to be material with respect to estimates for development quantities.

Thus far, Phase 1 and Phase 2 development has all been completed. The production and ventilation systems consist of Main Shaft, Main Ramp, Exploration Ramp, and Phase 1 and 2 ventilation shafts.

The Main Shaft (from +248 mRL to -370 mRL) is used for hoisting of ore, waste rock, equipment and materials, personnel, and for intake airflow for -100 RL and below levels.

The Main Ramp (portal elevation +176 mRL, bottom elevation reached -80 mRL) is used for transportation of ore, waste rock, equipment and materials, personnel, and for intake airflow for -500 mRL and above levels.

The Exploration Ramp is used for transportation of ore, waste rock, equipment and materials, personnel, and for intake airflow for +100 RL and +50 mRL levels.

At present, GC mine is extending the Main Ramp from -50 mRL to -300 mRL. There is a plan to extend the main ramp to -530 mRL for transportation of ore, waste rock, equipment and materials, personnel, and for intake airflow for -300 mRL level and below.

Market Studies and Contracts

AMC understands that the Gaocheng concentrates are marketed to existing smelter customers in Henan province in China and appropriate terms have been negotiated for 2019.

AMC also understands that an acceptable arsenic level in base metal concentrates, without penalty, for Chinese smelters is of the order of 1.0% and notes that the GC lead and zinc concentrates are acceptable to those smelters. AMC also notes the Silvercorp concentrate selling arrangements whereby:

• Should the As level ever be higher than 1.0% in zinc concentrates, the payable Zn content would be discounted by 0.5% Zn for every 1% As above the 1.0% As level.

• For instances where the pyrite concentrate has an As content above 1.0%, a penalty is paid on a case by case basis.

Smelter and Concentrate Sales Contracts

Sales contracts are in place for the lead concentrates with Shandong Humon Smelting Co. Ltd., and for the zinc concentrate with Chenzhou Qiantai Industrial Co. Ltd. and Henan Yuguang Zinc Industry Co. Ltd.

All contracts have an effective period of one year, with key elements of the contracts subject to change based on market conditions when monthly supplemental agreements to the annual contracts are negotiated. AMC had previously indicated that a preferable arrangement would have been to see contracts as part of a LOM frame agreement; however, it also understands that these contracts should be viewed in the context of the existing operations and concentrate sales to these smelters and therefore does not view the apparently short term of the contracts as a material issue.

70

All contracts have freight and related expenses to be paid by the customers.

The key elements of the contracts are summarized in Table 20.

Table 20	Key elements of 2019 smelter contracts

	35 - 45	2,900	1500 - 2000	88
			1000 - 1500	87

With respect to lead and zinc terms, the above deductibles calculate out to 85 - 92% payable for the lead concentrate and approximately 70 - 78% for the zinc concentrate, at projected long-term prices. AMC considers these to be favourable terms relative to global smelter industry norms. Silver payables of approximately 90% are similarly in accord with industry norms.

At the time of the 2012 Technical Report, silver was seen as the likely major contributor to ore value at Gaocheng. Silver prices have remained at reasonable levels but improved zinc prices in recent years have elevated the importance of that metal to the Gaocheng operation. At potential long-term metal prices of $1.25/lb for zinc, $18/oz for silver and $1/lb for lead, approximately 46% of estimated net total revenue is attributed to zinc, 31% to silver, and 23% to lead.

Infrastructure, Permitting and Compliance Activities

The filtered tailings are conveyed to the TMF area via conveyor and then spread by bulldozer on a bench-by-bench basis. The tailings deposition method is dry stacking and filling (from bottom to top and stacking by bench to form the embankment), with concurrent rolling and compaction to the desired dry density standards.

The waste rock dump is located a short distance to the east of the mine portal. It is understood to have an immediate capacity of the order of 275,000 m³ (~558 kt). Underground waste rock produced to date has largely been used for construction purposes by Silvercorp or transported off site by local area persons, free of charge, again to be used for construction activities. The removal of waste rock from site is anticipated to continue for the foreseeable future. Waste rock could opportunistically be disposed of into shrinkage stope voids (with approximately 1.2 Mm³ or 2.3 million tons (Mt) void capacity) but this is not in the current mine plan.

Based on the GC environmental assessment report, AMC understands that waste rock at the GC mine has no significant acid-generating potential.

There is a 110 kilo volts (kV) substation near Gaocun, about 6 km from the mining area. This is fed from the Guangdong Province electrical grid system. Silvercorp uses this substation as the main source of power for the mine. Currently there are two overhead power lines for the 6 km route. Two 1,500 kV diesel generators are designated for emergency backup to the man-hoist, underground ventilation system, water pumping and essential services in the plant.

71

A 10 kV substation within the mining area provides power service for the entire operations area. The power supply and distribution in the process plant, mining area, administrative and living areas are configured based on needs.

Sewage treatment and water treatment plants operate at the mine site. Any water that is not recycled and is released to the environment is treated to comply with standing regulations.

Underground water is discharged to surface using conventional centrifugal pumps via pipelines installed in the Ramp, Ramp Shaft, and Main Shaft. Underground water pumped to surface is collected in ponds at the Ramp portal or Main Shaft for sediment settling prior to being pumped to the process plant water treatment station. In 2017, a total volume of 468,630 m³ of underground water was treated, including 268,844 m³ discharged and 199,786 m³ recycled.

There is a comprehensive repair workshop on surface for the maintenance of large-scale production equipment, vehicle repair, processing and repair of partial components, and the processing of emergency parts. It has the following services: tyre processing, maintenance, and servicing, welding, electrical, hydraulic, tools, parts, and materials warehouse. In addition, the mining contractor has its own mobile equipment surface workshop for repairs and servicing located adjacent to the Ramp portal.

There are also underground equipment workshop facilities that are composed of mining equipment maintenance workshop, equipment and spare parts store, dump oil depot, reserve electric locomotives, and tramcars maintenance workshop and stockpile yard.

The explosives warehouse was constructed in the valley to the south-east of the GC Mining Area.

A properly constructed containment for storage of fuel is located in the vicinity of the diesel generators and fuel dispensing facilities.

There is a mine dry facility near the portal accommodating lockers, change room, showers, and washrooms for the miners. The mine office complex is for administration and engineering functions and to provide working space for management, supervision, geology, engineering, and other operations support staff.

Silvercorp operates the mine using contractors for development and production. The operation and maintenance of Silvercorp's fixed plant is via Silvercorp personnel. Silvercorp provides its own management, technical services, and supervision staff to manage the GC mine operation.

Silvercorp has all the required permits for its operations on the GC Property and, in conjunction with safety and environmental certificates, these give Silvercorp the right to carry out full mining and mineral processing operations.

An Environmental Impact Assessment (EIA) report on the GC Project was prepared by the Guangdong Environmental Technology Centre (GETC) initially, and then reassessment is done periodically as required by regulations. An Environmental Permit was issued by the Department of Environmental Protection of Guangdong Province in June 2010.

There are no cultural minority groups within the general area surrounding the project. No records of cultural heritage sites exist within or near the GC project areas. The surrounding land is used predominantly for agriculture. The mining area does not cover any natural conservation, ecological forests, or strict land control zones.

Silvercorp has made a range of cash donations and contributions to local capital projects and community support programs, sponsoring university students and undertaking projects such as village road construction, and school upgrading and construction. Silvercorp has also made economic contributions to the local economy in the form of direct hiring and retention of local contractors, suppliers, and service providers.

72

A monitoring plan has been negotiated between the company and the local environmental protection department to meet the environmental management requirements of the project. Key components of the monitoring plan are water pollution monitoring, together with environmental air and noise monitoring. The monitoring work is carried out by qualified persons and / or a third-party contractor and is undertaken on a regular basis.

Capital and Operating Costs

FY2020 budget is based on mining 271,500 tonnes of ore (milling 272,000), of which 78% would be by shrinkage and 22% by resuing. Other major operational requirements budgeted are waste development at 5,348 m, exploration tunnelling at 12,129 m, and drilling at 20,000 m. Sustaining development of 715 m is also budgeted.

All major infrastructure for operation of the Gaocheng mine is in place, including that for the potential production rate increase to 1,600 tons per day (tpd). FY2020 non-sustaining capital for further main ramp development and a backfill plant is budgeted at $3,538,000. FY2020 sustaining capital is budgeted at $1,662,000, which equates to $6.12 per tonne of ore projected to be mined.

Mining operating costs are categorized by direct mining (shrinkage or resuing), waste development, exploration tunnelling, drilling, and common costs. Other budgeted operating costs are for milling, general and administrative items, and government fee, Mineral Resources tax, and other taxes. The operating cost breakdown for the FY2020 budget is as follows: mining - $40.94/tonne, milling - $15.33/tonne, G&A -$6.76/tonne, Mineral Resources tax, etc. - $5.13/tonne, for a total budget operating cost of $68.17/tonne.

Contractor costs are the major component of the mining cost. The principal components of the milling costs are utilities (power and water), consumables (grinding steel and reagents), and labour.

The Gaocheng mine has been in commercial production for five years. From FY2020 onwards, a 12-year LOM is envisaged for the resource as currently understood at an average annual production rate of 300,000 tonnes. Average silver equivalent grades are projected to be of the order of 334 g/t for the first six years and then 271 g/t for the remainder of the mine life.

A base case NPV at 8% discount rate of $107M (pre-tax), $80M (post-tax) is projected for the 12-year LOM.

Exploration and Development

As per recommendations made in the GC Report, the Company plans to continue exploration tunneling and diamond drilling at Gaocheng. The exploration tunneling is used to upgrade the drill-defined Resources to the Measured category, and the diamond drilling is used to expand and upgrade the previous drill-defined Resources, explore for new mineralized zones within the unexplored portions of vein structures, and test for extensions of the vein structures.

Cautionary Note to U.S. Investors Concerning Estimates of Measured Resources and Indicated Resources: This section uses the terms 'Measured Resources' and 'Indicated Resources'. We advise U.S. investors that these terms may not be comparable to similar terms under the SEC Modernization Rules. The estimation of Measured Resources and Indicated Resources involves greater uncertainty as to their existence and economic feasibility than the estimation of Proven and Probable Mineral Reserves. U.S. investors are cautioned not to assume that mineral resources in these categories will be converted into reserves. See 'Cautionary Note to U.S. Investors Concerning Preparation of Mineral Resource and Mineral Reserve Estimates'.

Cautionary Note to U.S. Investors Concerning Estimates of Inferred Resources This section uses the terms 'Inferred Resources'. We advise U.S. investors that this term may not be comparable to similar terms under the SEC Modernization Rules. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources. U.S. investors are cautioned not to

73

assume that estimates of Inferred Mineral Resources exist, are economically minable, or will be upgraded into Measured Resources or Indicated Mineral Resources. See 'Cautionary Note to U.S. Investors Concerning Preparation of Mineral Resource and Mineral Reserve Estimates'.

The members of the Committee and the Chair of the Committee shall be selected annually by the Board and serve at the pleasure of the Board.

Additionally, at least one member of the Committee shall: be financially sophisticated, in that he or she shall have past employment experience in finance or accounting, requisite professional certification in accounting, or any other comparable experience or background which results in the individual's financial sophistication, which may include being or having been a chief executive officer, chief financial officer, or other senior officer with financial oversight responsibilities; and be an 'audit committee financial expert' within the meaning of U.S. federal securities laws. None of the members of the Committee may have participated in the preparation of the financial statements of the Company or any current subsidiary of the Company at any time during the past three years.
