PRELIMINARY NOTES

Incorporation of Financial Statements and MD&A

The following documents are incorporated by reference and form part of this annual information form (the “Annual Information Form” or “AIF”) which is prepared in accordance with Form 51-102F2 –Annual Information Form(“Form 51-102F2”). These documents may be accessed using the System for Electronic Documents Analysis and Retrieval (“SEDAR”) atwww.sedar.com:

Consolidated financial statements for the year ended December 31, 2010, together with the auditors’ report thereon dated March 31, 2011;

Management’s discussion and analysis (MD&A) for the year ended December 31, 2010.

Forward Looking Statements

This report contains forward-looking statements concerning anticipated developments on the Company’s continuing operations in Eritrea; planned exploration and development activities; the adequacy of the Company’s financial resources; financial projections, including, but not limited to, estimates of capital and operating costs, production, grades, processing rates, life of mine, metal prices, exchange rates, reclamation costs, net present value, internal rates of return and payback; and other events or conditions that may occur in the future. Forward-looking statements are frequently, but not always, identified by words such as “expects”, “anticipates”, “believes”, “intends”, “estimates”, “potential”, “possible”, “budget” and similar expressions, or statements that events, conditions or results “will”, “may”, “could” or “should” occur or be achieved. Information concerning the interpretation of drill results and mineral resource and mineral reserve estimates also may be deemed to be forward-looking statements, as such information constitutes a prediction of what mineralization might be found to be present if and when a project is actually developed. Forward-looking statements 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 due to a variety of risks, uncertainties and other factors, including, without limitation, those described in this Annual Information Form.

The Company’s forward-looking statements are based on the beliefs, expectations and opinions of management on the date the statements are made and the Company assumes no obligation to update such forward-looking statements in the future except as required by law. For the reasons set forth above, investors should not place undue reliance on forward-looking statements.

Information Concerning Preparation of Reserve and Resource Estimates

All reserve and resource estimates included in this Annual Information Form have been prepared in accordance with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects(“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum’s Classification System.These standards differ significantly from the requirements of the United States Securities and Exchange Commission (the “SEC”), and reserve and resource information included herein may not be comparable to similar information concerning U.S. companies. Under SEC Industry Guide 7, mineralization may not be classified as a “reserve” unless the determination has been made that is “part of a mineral deposit which could be economically and legally extracted or produced at the time of the reserve determination”. In addition, the term “resource” does not equate to the term “reserve”. The SEC’s disclosure standards normally do not permit the inclusion of information concerning “measured mineral resources”, “indicated mineral resources” or “inferred mineral resources” in documents filed with the SEC, unless such information is required to be disclosed by the law of the Company’s jurisdiction of incorporation or of a jurisdiction in which its securities are traded. Accordingly, information concerning descriptions of mineralization and resources contained in this Annual Information Form may not be comparable to information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC.

Glossary and Defined Terms

The following is a glossary ofcertain mining terms used in this Annual Information Form.

alteration:

Refers to process of changing primary rock minerals (such as quartz, feldspar and hornblende) to secondary minerals (quartz, carbonate, and clay minerals) by hydrothermal fluids (hot water).

breccia:

A rock in which angular fragments are surrounded by a mass of fine-grained minerals.

CIM:

Canadian Institute of Mining, Metallurgy and Petroleum.

doré:

a semi-pure alloy of gold and silver, usually created at the site of a mine. It is then transported to a refinery for further purification.

feasibility study:

A comprehensive study of a mineral deposit in which all geological, engineering, legal, operating, economic, social, environmental and other relevant factors are considered in sufficient detail that it could reasonably serve as the basis for a final decision by a financial institution to finance the development of the deposit for mineral production.

g/t or gpt:

Grams per metric tonne.

geotechnical work:

Tasks that provide representative data of the geological rock quality in a known volume.

gossan:

An iron-bearing weathered product overlying a sulphide deposit. It is formed by the oxidation of sulphides and the leaching-out of the sulphur and most metals, leaving hydrated iron oxides and rarely sulphates.

gravity:

A methodology using instrumentation allowing the accurate measuring of the difference between densities of various geological units in situ.

lithologic:

Pertaining to lithology

lithology:

The study of rocks, with particular emphasis on their description and classification.

mineralogic:

Pertaining to mineralogy

mineralogy:

The study of chemistry, crystal structure, and physical (including optical) properties of minerals. Specific studies within mineralogy include the processes of mineral origin and formation, classification of minerals, their geographical distribution, as well as their utilization.

- v -

mineral reserve:

The economically mineable part of a measured mineral resource or indicated mineral resource demonstrated by at least a preliminary feasibility study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified. A mineral reserve includes diluting materials and allowances for losses that may occur when the material is mined.

probable mineral reserve:

The economically mineable part of an indicated mineral resource and, in some circumstances, a measured mineral resource demonstrated by at least a preliminary feasibility study. This study must include adequate information on mining, processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justified.

proven mineral reserve:

The economically mineable part of a measured mineral resource demonstrated by at least a preliminary Feasibility Study. This study must include adequate information on mining, processing, metallurgical, economic, and other relevant factors that demonstrate, at the time of reporting, that economic extraction is justified.

The terms “mineral reserve”, “proven mineral reserve”, “probable mineral reserve”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” used in this Annual Information Form are Canadian mining terms as defined in accordance with NI 43-101 under the guidelines set out in the CIM’s Definition Standards on Mineral Resources and Mineral Reserves adopted by the CIM Council, as those definitions may be amended from time to time by CIM (the “CIM Standards”).

Under SEC Industry Guide 7, a mineral “reserve” is defined as a part of a mineral deposit which could be economically and legally extracted or produced at the time the mineral reserve determination is made, where:

A “final” or “bankable” feasibility study is required to meet the requirements to designate reserves;

A historic three year average price is to be used in any reserve or cash flow analysis to designate reserves; and

To meet the “legal” part of the reserve definition, the primary environmental analysis or document should have been submitted to governmental authorities.

Mineral reserves are categorized as follows on the basis of the degree of confidence in the estimate of the quantity and grade of the deposit.

Under SEC Industry Guide 7, proven or measured reserves are defined as reserves for which (a) quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes; (b) grade and/or quality are computed from the results of detailed sampling and (c) the sites for inspection, sampling and measurement are spaced so closely and the geographic character is so well defined that size, shape, depth and mineral content of reserves are well established.

- vi -

Under SEC Industry Guide 7, probable or indicated reserves are defined as reserves for which quantity and grade and/or quality are computed from information similar to that of proven reserves (as defined under SEC Industry Guide 7), but the sites for inspection, sampling, and measurement are further apart or are otherwise less adequately spaced. The degree of assurance, although lower than that for proven mineral reserves, is high enough to assume continuity between points of observation.

mineral resource:

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

inferred mineral resource:

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

indicated mineral resource:

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

measured mineral resource:

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

While the terms “mineral resource,” “measured mineral resource,” “indicated mineral resource,” and “inferred mineral resource” are recognized and required by Canadian regulations, they are not defined terms under SEC Industry Guide 7. As such, information contained in this report concerning descriptions of mineralization and resources under Canadian standards may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC. “Inferred mineral resources” have a great amount of uncertainty as to existence and a great uncertainty as to economic and legal feasibility. It can not be assumed that all or any part of an “inferred mineral resource” will ever be upgraded to a higher category. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into mineral reserves.

- vii -

mineralization:

An anomalous occurrence of metal or other commodity of value defined by any method of sampling (surface outcrops, drill core, underground channels).

multiple indicator kriging:

The probability in the distribution of values using deciles that are transformed to 1, if equal or less than the value or 0, if greater than the value, used to determine the average of a group of values.

ore:

Rock, generally containing metallic or non-metallic materials, which can be mined and processed at a profit.

pyrite:

An iron sulphide mineral (FeS2), the most common naturally occurring sulphide mineral.

sphalerite:

Zinc sulphide mineral (Zn Fe)S.

strike:

The direction, or bearing from true north, of a vein or rock formation measured on a horizontal surface.

sulphide (sulfide):

A compound of sulphur (sulfur) and some other metallic element.

supergene:

A word suggesting an origin literally “from above”. It is used almost exclusively for processes involving water, with or without dissolved material, percolating down from the surface. Typical supergene processes are solution, hydration, oxidation, deposition from solution, reactions of ions in solution with ions in existing minerals (replacement or enrichment).

tailings:

Gangue minerals extracted from ore through various mineral processes and deposited in an enclosed ground storage area.

trenching:

The mechanical or human excavation of ground material to expose material below surface.

UTM

The Universal Transverse Mercator coordinate system.

VMS:

Volcanic hosted massive sulphides.

WGS84

The World Geodetic System, 1984.

Reporting Currency

All dollar amounts are expressed in United States dollars unless otherwise indicated. The Company’s quarterly and annual financial statements are presented in United States dollars.

GENERAL DEVELOPMENT OF THE BUSINESS

2.1

Three Year History

Nevsun is a gold and base metal mining and exploration company. The most significant activities impacting the Company during the past three financial years, including subsequent activities up to the date of this filing are:

In March 2011, the resource and reserve re-statement of gold, copper, zinc and silver in the Company’s Bisha property in Eritrea (the “Bisha Property” or “Bisha”).

In February 2011, achievement of commercial production at Bisha, after completion of mine construction and commencement of commissioning in Q4 2010.

In 2010, commencement of resource expansion drilling at the Harena deposit, 9 km southwest of Bisha.

In August 2010, the buy-out of 1.5% Bisha net smelter return royalty.

In March 2010, the commencement of pre-strip mining.

In February 2010, the closing of a Cdn$117 million non-brokered private placement to provide funding to complete the Bisha construction, in lieu of debt facilities previously arranged.

In December 2009, imposition of United Nations Security Council sanctions on Eritrea, thereby casting doubt on the availability of the 2009 debt facilities.

In July 2009, the announcement of debt facilities for the Bisha project totaling $235 million followed in October 2009 by the announcement of the closing of a Cdn$32.8 million non-brokered private placement. The debt facilities were never drawn.

In 2008, the start of Bisha construction at with the ordering of critical equipment and the mobilization of SENET (PTY) Ltd. of South Africa ("SENET"), the engineering, procurement, construction and management (“EPCM”) contractor, for site preparation and camp construction.

10.

In October 2008 a commitment of $89 million for the development of the Bisha Property was received from Industrial Development Corporation of South Africa (“IDC”) towards the planned project finance of over $200 million from a consortium of lenders.

11.

In January 2008 the Company received $25 million from ENAMCO as a partial payment to be applied towards to the purchase by ENAMCO of a 30% interest in the Bisha Property pursuant to an agreement with the Company reached in 2007.

Changes which will impact the Company in 2011 include the advancement of Bisha mine to full operation, significant revenue from operations, evaluation of opportunities for corporate growth, results of exploration programs in Eritrea, and potential acquisitions or exploration programs in other areas.

The Company is managed from its Canadian head office where a small team of professional staff provide direction and support for the Company’s foreign operations.

Significant Acquisitions and Dispositions

During 2010 the Company was not involved in any significant acquisitions or dispositions.

ITEM 3.

DESCRIPTION OF THE BUSINESS

3.1

General

The Company is a natural resource company engaged in the acquisition, exploration, development and production of mineral properties. Currently the Company’s portfolio consists of the Bisha Property located in Eritrea, North-East Africa with gold and base metal (copper and zinc) mineral resources and mineral reserves.

In February 2011, Bisha achieved commercial production after having progressed through project development from 2008, commissioning in October 2010 and operational ramp-up of the mine and processing plant to the first gold pour in late December 2010.

The Company’s arrangement of a non-brokered private placement financings of Cdn$117 million in February 2010 and Cdn $32.8 million in October 2009 were instrumental to this achievement, together with development capital provided by ENAMCO.

Sales of gold commenced during the commissioning phase; prior to commercial production the Company had metal sales proceeds of approximately $57 million to offset capital costs at completion of approximately $247 million. Gold doré is flown from the Bisha site to the capital city of Asmara, and then shipped by air to refiners in Europe and Canada.

Methods of Production

The Bisha Property uses an owner operated mining fleet and standard carbon-in-leach (CIL) processing facilities to initially process the gold oxide cap by traditional cyanide leaching and then will process supergene and primary ores by flotation to extract copper and zinc. The current mine life is estimated to be at least thirteen years and the Company expects to expand resources to extend mine life by way of a number of planned drill programs for 2011.

Skill and Knowledge

The Company has built a management team of skilled mining, environmental, financial and administrative personnel reporting to a country General Manager who is in charge of mine production, exploration programs and future operations of the Bisha Property. The specialized knowledge and skills required in all areas of mining include engineering, geology, metallurgy, environmental permitting, drilling and exploration program planning. The Bisha Property is the first modern mining operation in Eritrea. Training and re-training of local staff in all aspects of mining operations is and has been a priority.

Employees

At December 31, 2010, the Company had 8 employees in Canada, 550 full time employees in Eritrea and another 250 casual or part-time staff.

- 4 -

Social, Environmental, Health and Safety

The Board has appointed a Social, Environmental, Health and Safety (“SEHS”) Committee to review SEHS standards in accordance with its Mandate and the laws, regulations and policies of the countries in which the Company operates. The SEHS Committee has the following duties and responsibilities:

Encourage the development of: (i) a culture of environmental responsibility; and (ii) an awareness of the importance of health and safety.

Assist management in defining the objectives set out in the Company’s Environmental Policy; monitor its effectiveness and, from time to time, discuss with management any necessary improvements to such policy and its framework of implementation.

Assist management in implementing an environmental compliance audit program, request periodic status reports on such programs and provide feedback on necessary improvement to the program.

Assist management in implementing appropriate health and safety programs, monitor their effectiveness and, from time to time, discuss with management any necessary improvements to such programs and their framework of implementation and request and obtain regular reports on such programs.

Report on its activities on a regular basis to the Board, and annually to shareholders in the Company’s annual reports.

Experienced environmental management staff report directly to the General Manager. Regular meetings are held between the Company and the local community. The Company focused much of its development work on the local community through education and community awareness programs, which were an integral part of the Bisha Property Social and Environmental Impact Assessment (the “SEIA”). There was full community involvement in the SEIA and the Bisha mine was developed in compliance with the 2006 World Bank Performance Standards on Social and Environmental Sustainability as applied in accordance with the Equator Principles.

The Company is committed to achieving the highest standards of environmental responsibility, safety in its operations and compliance with all applicable regulations and laws. To the end of February 2011 the Bisha construction had over 6.6 million man hours with only 6 lost time injuries, the most serious of which was a finger amputation.

3.2

Risk Factors

The operations of the Company are highly speculative due to the high-risk nature of its business, in the mining industry. The risks below are not the only ones facing the Company. Additional risks not currently known to the Company, or that the Company currently deems immaterial, may also impair the Company’s operations. Any of the following risks have the potential to adversely affect the Company’s business, financial condition and operating results.

Commodity price risk. The Company does not enter into any commodity hedging and accordingly is fully exposed to price risk. The price of gold and other metals can and has experienced volatile and significant price movements over short periods of time, and is affected by numerous factors beyond the control of the Company, including international economic and political trends, expectations of inflation, currency exchange fluctuations (specifically, the U.S. dollar relative to other currencies), interest rates, global or regional consumption patterns, speculative activities and increased production due to improved mining and production methods. The supply of and demand for metals are affected by various factors, including political events, economic conditions and production costs, and governmental policies.

- 5 -

Share price risk. The market price of a publicly traded stock, particularly a junior resource issuer like the Company, is affected by many variables not directly related to the success of the Company, including the market for all junior resource sector shares, the breadth of the public market for the stock, and the attractiveness of alternative investment. The effect of these and other factors on the market price of the common shares of the Company on the exchanges on which the common shares are listed suggests that the share price will be volatile. In the previous eight quarters, between January 1, 2009 and December 31, 2010 the Company’s shares traded in a range between Cdn $0.90 and Cdn $7.54.

Development and Operating risks. Mining operations generally involve a high degree of risk. The Company’s operating mine in Eritrea is subject to all the hazards and risks normally associated with mineral production, including damage to or destruction of plant and equipment, unexpected geologic formations, pit collapse, injury or life endangerment, environmental damage, fire, equipment failure or structural failures, such as retaining walls or tailings dams, potentially resulting in environmental pollution and consequent liability. The payment of such liabilities may have a material, adverse effect on the Company’s financial position.

The marketability of natural resources that may be acquired or discovered by the Company will be affected by numerous factors beyond its control. These factors include market fluctuations, the proximity and capacity of natural resource markets and processing equipment, and government regulations, including regulations relating to prices, taxes, royalties, land tenure, 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.

Foreign Operation and Political risk. The Company conducts operations through foreign subsidiaries with financial assets in Barbados and mining operations in Eritrea, and substantially all of its assets are held in such entities. While the Company believes that the political climate of these countries and strong government support in Eritrea provide a favourable environment for its operations, there is no guarantee against any future political or economic instability in these countries or neighbouring countries which might adversely affect the Company.

Recent political unrest in Egypt, Libya, Yemen and other countries in the region has had an impact on investor confidence with companies operating in northern Africa including Eritrea, even though no direct effect is evident or anticipated in the operations at Bisha or communications with the Eritrean government. In addition, intervention by the international community through organizations such as the United Nations can affect the political risk of operating in Eritrea. In December 2009 the United Nations Security Council imposed sanctions on Eritrea related to an arms embargo, which in itself has no direct impact to the Bisha Project, except to cause some uncertainty as to how UN member states may continue to deal with the country. Other effects may include limitations on the transfer of cash or other assets between the parent corporation and such entities, or among such entities, which could restrict the Company’s ability to fund its operations efficiently. All or any of these factors, limitations, or the perception thereof could impede the Company’s activities, result in the impairment or loss of part or all of the Company’s interest in the properties, or otherwise have an adverse impact on the Company’s valuation and stock price.

Infrastructure risk. Mining, processing and development activities depend, to some degree, on adequate infrastructure. Reliable roads, bridges, power sources and water supply are important determinants that affect capital and operating costs. Unusual or infrequent weather phenomena, sabotage, government or other interference in the maintenance or provision of such infrastructure could adversely affect the Company’s operations, financial condition and results of operations.

Key executive risk. The Company is to a large degree dependent on the services of key executives and senior personnel. Due to the relatively small size of the Company, the loss of these persons or the Company’s inability to attract and retain executives and personnel with the qualifications necessary to operate the business successfully may adversely affect its business and future operations.

- 6 -

Reserve and resource estimate risk. The figures for reserves and resources presented herein and contained in the Company’s continuous disclosure documents filed on SEDAR (www.sedar.com) are estimates, and no assurance can be given that the anticipated tonnages and grades will be achieved or, in the case of reserves, that the indicated level of recovery will be realized. Market fluctuations in the price of mineral commodities or increases in the costs to recover minerals may render the mining of ore reserves uneconomical and require the Company to take a write-down of the asset or to discontinue development or production. Moreover, short-term operating factors relating to the reserves, such as the need for orderly development of the ore body or the processing of new or different ore grades, may cause a mining operation to be unprofitable in any particular accounting period.

Prolonged declines in the market price of metals may render mineral reserves containing relatively lower grades of mineralization uneconomic to exploit and could reduce materially the Company’s mineral reserves and mineral resources. Should such reductions occur, material write downs of the Company’s investment in mining properties or the discontinuation of development or production might be required, and there could be material delays in the development of new projects, increased net losses and reduced cash flow.

There are numerous uncertainties inherent in estimating quantities of mineral reserves and resources. The estimates are based on various assumptions relating to metal prices and exchange rates during the expected life of production, mineralization of the area to be mined, the projected cost of mining, and the results of additional planned development work. Actual future production rates and amounts, revenues, taxes, operating expenses, environmental and regulatory compliance expenditures, development expenditures and recovery rates may vary substantially from those assumed in the estimates. Any significant change in these assumptions, including changes that result from variances between projected and actual results, could result in material downward or upward revision of current estimates.

Environmental risk. The Company’s operations are subject to environmental regulations promulgated by the government of Eritrea. Environmental legislation provides for restrictions and prohibitions on spills, releases or emissions of various substances produced in association with certain mining industry operations, such as seepage from tailings disposal areas that could result in environmental pollution. A breach of such legislation may result in the imposition of fines and penalties. Environmental legislation is evolving in general in a manner that means standards and enforcement, fines and penalties for non-compliance are becoming more stringent. Environmental assessments for projects carry a heightened degree of responsibility for companies, directors, officers and employees. The cost of compliance with changes in government regulations has the potential to reduce the profitability of operations. The Company intends to fully comply with all environmental regulations in the countries in which the Company has operations and comply with prudent international standards.

The Company adopted the IFC Social and Environmental Performance Standards of April 2006 and developed its management plans accordingly. The plans have been subject to review by both country hosts as well as part of an extensive due diligence by international bankers who at one time were considered for funding. The social and environmental plans have been implemented and have subsequently been audited by an independent third party. Staff training and engagement with local authorities, as well as significant employment from both local and other in-country sources are key elements of the Company’s social and environmental management. Our department heads for both Human Resources and Environment are experienced professionals with a solid understanding of local requirements as well as IFC Performance Standards. The Company continues to place significant emphasis on all social and environmental impacts of its operations.

Exploration risk. Exploration for mineral deposits involves significant risk that even a combination of careful evaluation, experience and knowledge may not eliminate. The discovery of ore bodies may or may not result in economically recoverable reserves, or be otherwise useful to the Company by adding to current reserves or providing feed for existing operations. There is no certainty that expenditures made by the Company towards the search and evaluation of mineral deposits will result in discoveries or future development.

- 7 -

Ownership risk. There is no guarantee that title to the properties in which the Company has an interest will not be challenged or impugned. Title to these properties may be affected by undetected defects, previous agreements, transfers or other valid challenges to the title of the Company’s property interests.

Currency risk. At present all of the Company’s activities are carried on outside of Canada and are subject to risks associated with fluctuations of the rate of exchange of foreign currencies. The United States dollar (USD) is the Company’s functional currency, exposing the Company to risk on any fluctuations of the USD with other currencies to which the Company is exposed, which are primarily the European euro (EUR), Canadian dollar (CAD), British pound (GBP) and South African rand (ZAR).

Funding risk. Historically, the Company has financed its activities through the sale of equity capital. The sale of metals from Bisha currently provides and will continue to provide revenue from operations, which the Company expects will be sufficient to fund its future needs. However, factors which may impact cash flows include changes in metal prices, taxes, operating costs, capital expenditures or other unexpected occurrences such as slowdown or stoppage of operations. Failure to obtain sufficient financing to continue operations if such needs arise may adversely affect the Company’s business and financial position. Should the Company require additional funding for exploration, development, operations, acquisitions or other activities, there is no assurance that sources of financing will be available on acceptable terms or at all.

3.3

Mineral Properties: Bisha, Eritrea

The Company has one material mineral property located in Eritrea. Commissioning of the plant at Bisha commenced in October 2010. Commercial production at Bisha was achieved in February, 2011.

Project Description and Location

The Bisha Property is located 150 km west of Asmara, 43 km southwest of the regional town of Akurdat, and 50 km north of Barentu, the regional or Zone Administration Centre of the Gash-Barka District, in Eritrea, East Africa. Current onsite Project infrastructure includes; an open pit, process plant, tailings and waste rock storage facilities, offices, maintenance and laboratory facilities, fuel storage areas, on-site power plant and an airstrip

The property area contains the Bisha deposit, which is a large precious metal (Au) and base metal rich (Cu, Zn) VMS deposit, as well as two satellite deposits, known as the “NW Zone” and the “Harena Zone”. A mining license, valid for 20 years, was issued for the project during 2008 covering a 16.5 square kilometer area (which includes the deposit known as the “Bisha Main Zone” deposit and the “NW Zone” deposit) within a mining agreement area of 39 square kilometres (the “Mining License”). The Company retains a continuous exploration license of 71 square kilometers, including the Harena deposit (the “Exploration License”). The Bisha Property is located at approximate latitude 15°28'N and longitude 37°27'E. The UTM coordinates (WGS84) of the centre of the Bisha Property are 1,711,000 N and 334,500 E (UTM Zone 37). The Exploration License is valid until May 10, 2011 with a right of renewal upon application and a minor fee. The Company intends to apply for renewal and may shed a portion of the Exploration License that is not prospective.

The annual rental fee for the Exploration Licence is 53,200 Nakfa, and the annual licence renewal fee is 6,000 Nakfa (about US$3,500 and US$400 respectively).

The Mining License and the Exploration License are held by Bisha Mining Share Company (“BMSC”).

In October 2007 the Government of Eritrea indicated its strong support for the Bisha Project and for the development of a new and strong mining sector in Eritrea through its purchase of a 30% paid participating interest through ENAMCO. The final purchase price and settlement for the 30% interest is to be determined in the future, as disclosed in the notes to the Company’s annual financial statements. The shareholder structure of the BMSC is 60% Nevsun and 40% ENAMCO; with the ENAMCO shareholding comprising a 30% paid participating interest and a 10% free participating interest as provided by the country’s mining legislation. In December 2007 BMSC concluded a mining agreement with the Government of the State of Eritrea containing all the normal provisions governing the future development and operations for the Bisha Project, including all substantive requirements of international financial institutions.

Royalties payable include an Eritrean Government royalty of 5% of precious metal net smelter return (NSR) and 3.5% of base metal NSR.

Accessibility, Climate, Local Resources, Infrastructure & Physiography

Eritrea is located above the Horn of Africa on the continent’s east coast, between Sudan to the north and west, and Ethiopia and Djibouti to the south. Eritrea has an area of 124,320 km²and a 1,151 km long coastline on the Red Sea, which separates the country from Saudi Arabia and Yemen.

The country is divided into three main geographical zones: (1) the fertile and intensively farmed mountainous central plateau that varies from 1,800 to 3,000 metres above sea level (“masl”); (2) the eastern escarpment and coastal plain which are mainly desert, and (3) semi-arid western lowlands. The Bisha Property is located in the western lowlands.

Eritrea has no year-round rivers and the climate is temperate in the mountains and hot in the lowlands. The weather is usually sunny and dry, with the short or “belg” rains occurring between February to April and heavy or “meher” rains beginning in late June and ending in mid-September.

Asmara, the capital, is located at about 2,300 masl (7,500 ft.) and is serviced by regular international flights including flights out of Frankfurt, Cairo, Sanaa and Jeddah. There is a good network of paved roads connecting Asmara with the major regional centres of Keren, Massawa, Assab, Adi Quala and Barentu. Power generation from the Hirgigo plant near Massawa supplies electrical power to Asmara and other major regional centres. Landline telephone service is available from larger towns and cellular service is available in Asmara and surrounding towns, including Keren. Access to the Bisha Property is by paved road from Asmara to Akurdat, a distance by road of 181 km. From Akurdat access is via an all-weather unpaved road.

Comprehensive medical services are found in the larger towns with rudimentary medical clinics available in the smaller villages. Schools are located in most villages.

Under the terms of the Mining Agreement, BMSC has the exclusive right of land use in the Mining License Area that is granted within the Mining Agreement Area. This right is subject to the acquisition and settlement of any third-party land-use rights by payment of compensation and/or relocation at the expense of BMSC, in accordance with Eritrean Government Proclamation No. 68/1995, “Proclamation to Promote the Development of Mineral Resources and the Mining Agreement”.

BMSC holds all the necessary permits to support a mining operation. For the mining operations, grant of the mining lease provides permission to construct and operate the Bisha mine. A permit has been granted for use of water from the Mogoraib River. Nevsun has also applied for a permit for a water diversion dyke. These permits are sufficient to ensure that mining activities at Bisha are conducted in accordance with the appropriate National laws.

Exploration

Nevsun has no record of any previous exploration or mining activities on the property or surrounding areas prior to 1998. In June 1998, Nevsun signed the Bisha Area Prospecting Licence Agreement with the State of Eritrea that was converted to the Exploration Licence in June 1999 covering an area of 49 km², later expanding to an area of 224 km² in 2003. From 1998 to 1999, exploration activities consisted of reconnaissance-scale geological mapping, multi-element stream sediment sampling, ground geophysical surveys and limited “orientation” soil sampling, which showed the Bisha Gossan Zone to be highly anomalous in lead with significant values of copper, zinc and silver. Grab samples of the gossan returned anomalous gold values ranging up to 30.4 g/t Au.

Work was suspended between 1999 until late 2002 due to the border war with Ethiopia.

In November 2002, Nevsun completed a diamond-drilling program of six holes totalling 811m at the Bisha Property to test the geophysical and geochemical anomalies at the gossan outcrop area. The drilling was sufficient to confirm the presence of a VMS deposit overlain by a supergene copper-enriched zone and a gold-enriched gossan cap.

Two phases of diamond drilling were completed in 2003 for a total of 18,619m in 141 holes. Additional work conducted during this program included mapping, geochemical sampling, trenching, geophysics (airborne and ground), metallurgical testwork, petrographic work and bulk density measurements.

Further diamond drilling (163 holes totalling 28,879m), RC drilling (33 holes totalling 1,814m) and core/RC combination holes (9 holes totalling 592m) were completed between January and June 2004. Additional work completed during this program included geophysical surveys, mapping, geochemical sampling, petrographic work, bulk density measurements, geotechnical work, environmental baseline work, and metallurgical testwork.

During 2005, Nevsun completed diamond drilling of 135 holes in three zones (86 holes in Bisha Main Zone, 22 holes in the NW Zone, 27 holes in the Harena Zone totalling 18,053m. The Bisha Main Zone drilling included 20 geotechnical and 8 metallurgical drill holes, drilled to provide further information on the deposit for use in the feasibility study on the Bisha Property dated November 15, 2006 and prepared by AMEC Americas Ltd. (the “Bisha Feasibility Study”).

In 2006, 8 diamond drill holes (1,680m), including one deep drill hole at the Bisha Main Zone, three drill holes at the Bisha hanging wall copper zone and 4 drill holes at the NW zone satellite deposit were completed. These holes were not included in the database used for resource estimation in the Bisha Feasibility Study.

In 2007 additional ground geophysical (gravity) surveys were performed on new target areas within the Exploration License which were followed up in 2008 with mechanical trenching/pitting and geological mapping.

In 2009, 29 diamond drill holes (3,578m) were completed in the Bisha Main Zone and in the Harena Zone. The Bisha Main Zone drilling consisted of 9 geotechnical holes to provide additional information for the pit design and 3 metallurgical holes, drilled to collect additional samples for designing the copper phase of the mill. Harena Zone drilling consisted of 17 infill holes drilled at 50m spacings to better define the mineralization. An additional ground gravity survey was also performed on the Exploration License to the southwest of the Harena Zone.

In June-July 2010, 13 diamond drill holes (1,918m) were drilled to test gravity targets within the Exploration License. No significant mineralization was intersected. During this program an additional 6 metallurgical holes were drilled in the Bisha Main Zone to collect additional samples for designing the copper phase of the mill. In November-December 2010, 34 diamond drill holes (2448m) were drilled to infill the Harena Zone to reduce the drill hole spacing to 12.5m x 25m and 25m x25m. This infill drilling was focused on defining the oxide and supergene mineralization.

Geology and Mineralization

Mineralization found to date within the Project is typical of precious and base metal-rich volcanogenic massive sulphide (VMS) deposits.

Eritrea is divided into several north or northeast trending Proterozoic terranes, which are separated by major crustal sutures. The Nacfa Terrane comprises low-grade metamorphosed calc-alkaline volcanics and sediments, and hosts base metal mineralization in the region surrounding the city of Asmara, and in the Gash-Barka district, including the Bisha polymetallic mineralization.

The VMS deposits at Bisha are hosted by a tightly and complexly folded, intensely foliated, bimodal sequence of generally weakly stratified, predominantly tuffaceous metavolcanic rocks. Felsic lithologies appear to directly host the mineralization, predominate overall, and form the hanging wall stratigraphy. A significant component of mafic metavolcanic rocks occurred in the more obviously bimodal footwall, which is exposed mainly to the east of the known mineralized zones.

The Bisha Main Zone deposit extends for over 1.2 km along a north-trending strike, and has been folded (and overturned, dipping to the west) into an antiform so that there are two western and one eastern lenses. The thickness of the lenses is variable from 0 m to 70 m. The primary sulphide zone is below the weathering zone. The massive sulphide lenses can locally exceed 70 m in true thickness and show typical copper-rich bases and zinc-rich tops.

Deep weathering has affected Bisha Main Zone lenses that occur in low-lying areas by removing most of the sulphide and producing high-grade supergene blankets enriched in gold, copper, and lead in particular. The gossan zone can vary in composition from highly siliceous and somewhat ferruginous to a massive goethite–hematite–jarosite gossan. The depth of oxidation appears to be on the order of 30 m to 35 m in outcrop areas, but is variable in sand-covered areas.

The oxidation of the massive sulphides generated strong acid solutions that have progressively destroyed the sulphides and host rock. A horizon of extremely acid-leached material or “soap” has developed between the oxide and supergene/primary domains.

The Harena deposit has been traced over a strike length of 400 m, and is interpreted to be a northwest-dipping, tabular massive sulphide body, closed off by drilling to the northwest, but open to the southeast. Host rocks to the Harena deposit are a bimodal, hydrothermally-altered suite of basalts and rhyolite-dacite volcanics. Surficial weathering processes have produced three distinct zones of mineralization. These include a surface oxide/gossan overlaying a secondary supergene horizon, which grades into a primary massive sulphide horizon at depth. The gossanous horizon contains frequently anomalous levels of gold and silver. Oxide and sulphide mineralized zones are approximately 400 m in length and vary in thickness between 5 m and 15 m.

Additional prospects are known within the Project area; the most advanced is the Northwest (NW) Zone, located approximately 1.5 km north of the Bisha Main Zone.

Drilling

Drilling on the Project has been undertaken in a number of core and one RC campaign from 2002 to 2011. Drilling comprised a total of 578 drill holes (78,880.96 m), of which 545 were core drill holes (76,783.66 m) and 33 were RC drill holes (2097.3 m). Drill programs have been completed primarily by contract drill crew, supervised by Nevsun geological staff.

A total of 356 drill holes support estimation at the Bisha Main Zone. Much of the massive sulphide mineralization in the Bisha Main Zone has been well defined by drilling patterns of 25 m spaced holes on sections spaced 12.5 or 25 m apart. This density decreases with depth on the deepest portions of the primary mineralization. The deposit remains open at depth in the south, with the deepest intersections obtained to date returning long lengths of medium- to high-grade zinc mineralization

Core was logged for geological and geotechnical parameters, and photographed. Drill collar locations have been verified by survey. Down-hole surveys were not performed for the first 20 drill holes on the Project; all subsequent drilling has been down-hole surveyed using acid tests, Sperry-Sun Single-Shot and Reflex instrumentation.

Average recoveries are 71% in the oxides, 71% in the breccia, 61% in the “soap” lithological unit, 91% in the supergene domain, and 98% in the primary sulphides. As most of the low-recovery assays were associated with the gold-rich oxidized portion of the deposit, a decision was made to remove all of the assays with core recoveries of less than 60% from the database that supported Mineral Resource estimation.

RC samples were 2 m in length. The maximum core sample length is 12.00 m (only within wall rock away from mineralized intervals) and the minimum is 0.15 m. Within the zones of mineralization, samples lengths are generally between 1.00 and 3.00 m. Sample intervals are determined based upon mineralogical and lithological contacts. Samples are considered to be adequately representative of the true thicknesses of mineralization.

One-metre grade control samples weighing approximately 6 kg are split in-pit and submitted to the on-site laboratory for sample preparation.

Sampling and Analysis

Sampling programs at the Bisha Property included drill core samples, RC samples and various geochemical samples, which included: surface rock chip, trench, auger, pit, soil, and stream sediment sampling. Nevsun established detailed logging, sample collection, and sample preparation protocols for core and RC sampling, and implemented procedures for the collection of geotechnical data.

All trench, rock chip and geochemical samples, including soil and auger, stream sediment, pit and termite mound samples collected during the drilling program conducted between February and June 2003 (the “2003 Phase I Program”) were shipped to the Horn of Africa Preparation Laboratory, in Asmara, which provided preparation services for Genalysis Laboratory Services Pty (Genalysis) of Maddington, Australia. The preparation laboratory produced pulp samples that were subsequently shipped to Genalysis in Australia for analysis. Following the 2003 Phase I Program, geochemical and rock chip samples were shipped to ALS Chemex Ltd. (ALS Chemex), in Vancouver, Canada.

- 12 -

The primary laboratory used by Nevsun for analytical work on the drilling programs was ALS Chemex. Nevsun used the laboratory for both sample preparation and analyses from the initiation of the first drill program in 2002. During the 2002 and 2003 Phase I Program samples were shipped as half-core from the Bisha camp to Asmara and forwarded to ALS Chemex in Vancouver. After establishing a sample preparation facility, designed and installed by ALS Chemex, at camp in September 2003, Nevsun sent coarse crushed and split material (-2 mm) for core, RC, and rock samples to ALS Chemex for subsequent pulverization and analyses. All assay data contained in the database for resource estimation was assayed by ALS Chemex.

Both ALS Chemex and Genalysis are registered with the International Organization for Standardization (“ISO”) and are internationally recognized facilities. ALS Chemex is registered to ISO 9001:2000 for the “provision of assay and geochemical analytical services” by BSI Quality Registrars. The National Association of Testing Authorities Australia has accredited Genalysis, following demonstration of its technical competence, to operate in accordance with ISO/IEC 17025 (1999), which includes the management requirements of ISO 9002:1994. The facility is accredited in the field of Chemical Testing for the tests, calibrations and measurements that are shown in the Scope of Accreditation issued by the National Association of Testing Authorities, Australia.

In 2009 the Company switched from ALS Chemex in Vancouver to ALS Chemex in Romania in order to save on shipping costs and to speed up turn-around times for getting analytical results. For additional metallurgical testing the Company has used Mintek of Randburg, South Africa and Maelgwyn Laboratories, South Africa.

Sample programs included insertion of blank, duplicate and Standar Reference Material (SRM) samples. The QA/QC program results do not indicate any significant problems with the analytical programs that would preclude use of the data.

The initial process of data verification for the Project was performed by Nevsun, and by external consultancies contracted by Nevsun staff. During the 2006 Feasibility Study, and as part of checks on data for this, and previous technical reports, AMEC reviewed drilling and other exploration and project data. AMEC also submitted independent samples for verification of mineralization tenor at the Project.

The run-of-mine laboratory was established by SGS Mineral Services, who trained BMSC staff as operators

A detailed description of the sampling methods and quality control procedures are described in the Company’s NI 43-101 report filed on SEDAR (www.sedar.com).

Security of Samples

The chain-of-custody for core samples collected and being shipped from site is as follows:

Core is transported to the Bisha camp by Nevsun personnel and placed in the core logging area.

The logging and sample preparation area and the Bisha camp is within a fenced and guarded compound.

Core samples are crushed and sub-sampled.

Prepared samples are placed in sealed barrels.

Each barrel has a list of samples written on the outside of the container.

A sample submission form accompanies each barrel.

Barrels are transported to Asmara in company-owned vehicles arranged by Nevsun.

- 13 -

The sample barrels are submitted to the Eritrean Ministry of Energy and Mines for inspection and submission to customs, a customs seal is placed on the barrels and they are shipped via air transport directly to ALS Chemex.

Mineral Resource Estimate

The resource model was prepared in 2005 by AMEC (S. Blower, P.Geo. under the supervision of Mr D. Reddy, P.Geo), and reviewed in 2009 by David Thomas, P.Geo. Mr Thomas is the Qualified Person for the Mineral Resource estimate.

The geological interpretation was completed by Nevsun based on lithologic, mineralogic and alteration features logged in drill core. The overall interpretation at the Bisha Property changed little since AMEC Americas Ltd. (“AMEC”) provided an initial resource estimate in 2004. The deposit has been subdivided into six mineralized domains: breccia, oxide, acid, supergene, primary Zn, and primary. Some of the domain contacts have been revised relative to the 2004 interpretation based on new drill hole information or revised interpretations. The general sizes of the domains and their positions relative to each other are consistent with the initial interpretations.

A 3D geological model was prepared in Gemcom® software to outline the six mineralized domains. A resource model was prepared in 2005 by AMEC using ordinary kriging for grade interpolation. The 2005 Bisha mineral resource estimate is based on 347 diamond and 9 reverse circulation pre-collar diamond drill holes covering a strike length of 1,200m and to depths varying from surface to 380m.

The classified Bisha mineral resource estimate is summarized within a constraining optimized pit shell by domain at marginal breakeven cut-off grades in Table 1-1. Mineral resources are defined using a gold price of $1,105/oz, silver at $15.85/oz, copper at $2.40/lb, and zinc at $0.92/lb.

The mineral resource estimate provided by AMEC is compliant with CIM Definition Standards for Mineral Resources and Mineral Reserves as required by NI 43-101.

After resource modelling was completed, the model was condensed to three zones each of which requires a different recovery treatment process. The upper breccia, oxide, and acidified domains were combined into an “Oxide Zone”. The supergene domain became the “Supergene Zone”, and the two primary domains were combined into the “Primary Zone”. The resulting zones were then examined to determine the potential for selective mining of each zone and a series of pit phases were created to sequence the pit. A dilution factor was added to the mineralization based on the zones and their grades in each block.

Notes to accompany Mineral Reserve Table:

Mineral Reserves are defined within a mine plan, with pit phase designs guided by Lerchs–Grossmann (LG) pit shells, generated using a gold price of $825/oz, silver at $12.50/oz, copper at $2.00/lb, and zinc at $0.75/lb and considering diluted Measured and Indicated resources. Metallurgical recoveries by ore type are 87% Au and 36% Ag for oxide mineralization reporting to dore, 56% Au, 54% Ag and 92% Cu for supergene mineralization reporting to Cu concentrate, 36% Au, 29% Ag and 85% Cu for primary copper mineralization reporting to copper concentrate, and 9% Au, 20% Ag and 83.5% Zn for primary zinc mineralization reporting to zinc concentrate. The mining cost was $1.46/t, plus $0.01/t/5m bench below the reference elevation of 560m. The total ore based costs (process, G&A and stockpile rehandle) are $29.03/t for oxide, $26.57/t for supergene and $26.68/t for primary ores. Overall pit slopes varied from 43 to 55.5 degrees in rock and 18.5 degrees in overburden.

Reserves are reported within the above mentioned pit phase designs, using an NSR grade item, where the marginal cut-off is the ore based cost stated above. After completion of the pit designs, the NSR was recalculated using a gold price of $1,015/oz, silver at $15.85/oz, copper at $2.40/lb, and zinc at $0.92/lb. Recoveries used for the NSR calculation are as above with the exception of the supergene copper recovery which was reduced from 92% to 88% based on recent metallurgical testwork.

Proven oxide Mineral Reserves are inclusive of 197 kt at 3.64 g/t Au in stockpile as of 01 January 2011.

Tonnages are rounded to the nearest 1,000 tonnes, grades are rounded to two decimal places.

The life of mine strip ratio is 4.16

- 16 -

The Bisha open pit mining operation features a single pit consisting of nine internal phases. The first three phases target the oxide ore, phases 4 to 6 target the Supergene ore, and phases 7 to 9 target the primary ore. The mine has an estimated life of approximately 12 years at the currently planned mill throughputs of 2.0 Mt/a for oxide, 2.4 Mt/a for supergene and 2.4 Mt/a for primary materials. Pre-stripping of the oxide area began in mid-2010, with ore delivery to the ROM crusher pad beginning in July, 2010.

The mining method is conventional selective open pit mining, with mining rates of approximately 22 kt/d during the oxide phase. Mining rates increase to a peak of just under 50 kt/d later in the mine life as deeper primary mineralization is mined with higher strip ratios.

Metallurgical Testwork and Process Plant Design

The Bisha Property mineral resource contains three ore types; the gold and silver bearing oxide cap, underlain by the secondary copper mineralized supergene ore, which is in turn underlain by the primary ore with chalcopyrite and sphalerite mineralization.

The metallurgical performances of the three ore types are summarized in Table 1 - 4.


Table 1 - 4 Metallurgical Performance of the Three Ore Types
	%Au Recovery	%Ag Recovery	%Cu Grade	%Cu Recovery	%Zn Grade	%Zn Recovery
Bullion from Oxide Ore	87	36	-	-	-	-
Cu Concentrate from Supergene Ore	56	54	30	88	-	-
Cu Concentrate from Primary Ore	36	29	25	85	3.9	2.1
Zn Concentrate from Primary Ore	9	20	0.3	3	55	83.5

The three ores will require different processing techniques and equipment. The current plan is to mine and process each zone in succession starting with the oxide zone. Before the oxide ore is exhausted the additional supergene ore process equipment will be installed and commissioned so that a smooth transition can be made from the oxide ore to the supergene ore. Similarly, before the supergene ore is exhausted, the additional equipment required to process the primary ore will be installed and commissioned to permit a smooth transition from supergene to primary ore. No interruption to production is anticipated or required when transitioning from one ore type to another.

The oxide ore will be processed by cyanide leaching and the supergene and primary ores will be processed by flotation. The crushing, grinding and tailing systems will be common for the three plants. In the first two years of production, gold and silver will be recovered by adsorption on carbon, stripped and recovered and then melted into doré bars and flown to refiners. Production of copper concentrate is expected to begin with a minor amount in Year 2, significant quantities for Years 3 to 5, and smaller quantities in Years 6 to 13. Zinc concentrate production occurs only in Years 6 to 13. Concentrate will be transported to a concentrate storage and load-out facility at the port of Massawa where it will be off-loaded and conveyed into the holding sheds for storage prior to loading onto ocean freighters for shipment to smelters.

In 2010, metallurgical testwork was conducted at Mintek on behalf of SENET to provide plant design and performance expectations of the Bisha supergene mineralization as part of ongoing development of the Bisha project. The test program was conducted in two phases. The phase 1 objective was to replicate test conditions set by SGS Lakefield (SGS) in 2005, and use those conditions to generate a bulk concentrate for marketing purposes. As the results of those tests indicated that the ore sample delivered to Mintek did not behave as the previously tested samples at SGS, it was decided that the concentrate production be put on hold and instead conduct scouting investigations on the reasons for the variable response. For phase 2, the approach was to use a simplified reagent scheme to enhance copper flotation kinetics and this met with limited success. Poor reproducibility resulted in the concentrate generation program being suspended to investigate the possible reasons for the different results.

Following the testwork at Mintek, Maelgwyn Mineral Services Africa (Pty), South Africa (Maelgwyn) was contracted to duplicate the test program previously attempted at Mintek. The objective of the test program at Maelgwyn was to advance the testwork initiated at Mintek and demonstrate that the results could be reproducible at the given conditions. At the time of reporting batch flotation tests on supergene samples have been completed and further testing is on-going.

The supergene test composite prepared for the Maelgwyn testwork contained 4.4% copper, 0.50% zinc, 43.2% iron and 46.3% sulphur. The final cleaner concentrate produced a copper recovery of 89% and a copper grade of 30.8%.

Starting with the copper production phase in 2013 the Company plans to increase throughput by 20%. The engineer for the copper phase expansion is nearing the completion of detailed design for constructing the copper flotation circuits taking into account this planned increase. Construction of the copper phase is planned to start later this year.

Mine life is extended as a result of increased reserves and the waste-to-ore strip ratio increases slightly to 4.2:1. Together with the impact of increased throughput, the estimated life of mine is now 13 years, excluding any potential extensions that may result from current drill programs designed to further expand resources.

Mine Waste and Water Management

Waste rock from the open pit will be placed in dumps adjacent to the pit. Waste rock with acid rock drainage potential will be placed to allow drainage flow by gravity into the open pit for closure. During operation, all waste dump drainage will be intercepted and used as mill process water or disposed in the tailings impoundment. The original waste rock dump plan, defined in the Bisha Feasibility Study and SEIA, was revised during 2009 to locate the waste rock dumps to the south of the open pit. This revision was undertaken to minimise the environmental impact, to optimise mine operations and to permit, if economically feasible, the later exploitation of a copper zone identified subsequent to the Bisha Feasibility Study and lying to the west of the currently defined open pit.

Tailings generated from the processes will be stored in an impoundment located in an area that provides the best available storage characteristics in terms of embankment construction requirements. Subsequent to the Bisha Feasibility Study, management decided to relocate the tailings impoundment to a more appropriate site adjacent to the plant site and to install an impermeable plastic (HDPE) liner within the basin. The additional cost has been included in capital cost updates below. The tailings will be thickened at the mill to reclaim as much water as possible for re-use in the mineral processing and cyanide will be destroyed prior to pumping to the tailings impoundment. Applicable SEIA revisions accounting for the changes in the project have been completed and approved by the Eritrean Ministries.

Surface water flow in the project area is non-existent for much of the year; however river and stream flow can be significant during precipitation events. A diversion system will divert the Fereketatet river course, upstream (southeast) of the project, and away from the open pit.

Infrastructure

The major infrastructure required to develop the property includes electrical power supply, and a well farm for freshwater supply. Electrical power for the first 2 years shall be by a containerised diesel generating plant to be supplied and operated by a reputable international contractor through a rental contract. At the conclusion of the rental the Company plans to install a permanent power generation plant fuelled by heavy fuel oil.

Freshwater will be supplied from groundwater produced from a combination of a well field located approximately 1.5 km southeast of the process plant site and another well field located approximately 6.5 km southeast of the process plant along the base of the slope of the adjacent mountain range.

A port site for the storage and loading of copper and zinc concentrate, produced from the later 2^nd (copper) and 3^rd (zinc and copper) phase of project development is planned for the site of an existing jetty at the Port of Massawa.

Socioeconomic and Environmental Assessment and Approval

The environmental assessment phase of this project commenced with baseline studies in 2004. The Terms of Reference for the project SEIA was approved by the Eritrean Ministry of Energy and Mines in March 2006 and the SEIA was completed in December 2006. During 2009 the Company completed an update report which augmented the 2006 SEIA and addressed the revisions to the configuration of the project that had occurred since the Bisha Feasibility Study. The project social and environmental management plans were extended to capture the additional details of the project resulting from the advancement of engineering and development and to ensure full compliance with the Eritrean National Standards, and the 2006 International Finance Corporation Performance Standards as applied to the Equator Principles. The Company continues to consult and work closely with government ministries on matters pertaining to social and environmental aspects and will continue to do so through the life of the mine. There have been no material adverse social or environmental impacts identified.

Capital Costs

An update to the Bisha Feasibility Study capital cost estimates was completed by management in June 2008 following the engineering design by SENET. The pre-production capital expenditure estimate was raised to $250 million from the $196 million in the Bisha Feasibility Study, and the future expansion capital was re-estimated to $115m versus the $92 million in the Bisha Feasibility Study. Similarly in January 2010, with the project approaching fifty percent (50%) completion, management, with the assistance of SENET, carried out a further updated evaluation for the complete of the Oxide Phase and increased the estimate to $260 million. The estimated cost at completion of $247 million is below the budgets established in January 2010 and June 2008.

- 19 -

The estimated capital cost (in millions of US$) to build each of the phases of this project is as follows:


	October 2006	June 2008	Jan 2010	February 2011
Phase	Bisha Feasibility Study¹	Update²	Update³	Estimated cost at completion²
Oxide	196.0	250.3	260.1	247.0
Supergene	61.2	76.5	76.5	(Funded from cash flow)
Primary	30.8	38.4	38.4	(Funded from cash flow)

In Q3 2006, US dollars, with no allowance for escalation, interest during construction or taxes.

In Q2 2008, US dollars, with no allowance for escalation, interest during construction or taxes.

In Q1 2010, US dollars, with no allowance for escalation, interest during construction or taxes.

The estimates cover the direct field costs of executing this project, plus the indirect costs associated with design, procurement, and construction efforts.

Operating Costs

The mine operating cost estimate incorporates costs for operating and maintenance labour and staff, plus operating and maintenance supplies for each year. Operating and maintenance supplies are based on African, Australian, North American, Asian and European supply and include an allowance for freight, shipping and delivery to the site.

The process operating costs assume an annual processing rate of 2 million tonnes for years one and two; 2.3 million tonnes for year three and 2.4 million tonnes for the remained of life of mine (LOM). The estimated breakdown of the process operating costs over the LOM is 4% for manpower, 41% for consumables and 55% for electrical power.

The bulk of the port site operating cost is associated with operation and maintenance of the truck dump receiving and ship loading systems.

The general and administration (G&A) operating costs will include all costs not directly chargeable to the mining, process and port site concentrate storage and ship loading areas. The costs will include administrative personnel salaries, general office supplies, safety and training supplies, travel, contracted consultant services, insurance, permits, security, accommodations, building maintenance (excluding the process building and truck shop), environmental management and employee transportation.

The estimated operating costs over the mine life are summarized in Table 1 - 5. Note: All costs in the table below are from the March 2011 revised reserves Bisha update report.

Financial Analysis

A summary of the financial analysis is shown in Table 1 - 6 which is based on the March 2011 revised reserves Bisha update report.

In the March 2011 revised reserves Bisha update report, sensitivity analyses were performed on the base case cash flow. Positive and negative variations were applied independently to each of the following parameters:

Metal prices – a change in metal price has the same effect as a similar change in grade or recovery rate (limited to an upper bound below 100%).

Operating cost.

- 20 -

The results of this analysis show that the project’s financial outcome is most sensitive to variation in metal price. The project is less sensitive to changes in operating cost.


Table 1 - 6 Financial Analysis Summary
Economic Parameter	LOM (Total or Average)
Life of Mine	13 years
Total Gold Production	1.1 million oz
Total Copper Production	821 million lb
Total Zinc Production	1,373 million lb
Total Silver Production	11.9 million oz
Pre-production Capital Cost	$247 million
Expansion Capital Estimate	$80 million + $40 million in two phases, funded from operations
Additional Sustaining Capital	$ 27 million
Operating Costs	$43.82 per tonne ore milled through LOM

The revised March 2011 cost estimates provide for the following management estimates of net after tax cash at varying metal prices for life of mine. These projections are based on a financial model that involves no debt.


Table 1 - 7 Metals price sensitivity (US$000)
Sensitivity Scenarios	Net Future Cash⁽¹⁾	Metals Prices Used
Low metals price case	$1,034,000	$850/oz Au; $12.50/oz Ag; $2.00/lb Cu; $0.75/lb Zn
Base metal price case	1,484,000	$1015/oz Au; $15.85/oz Ag; $2.40/lb Cu; $0.92/lb Zn
Medium metals price case	$2,162,000	$1,200/oz Au; $24/oz Ag; $3.30/lb Cu; $1.00/lb Zn
High metals price case	$3,325,000	$1,500/oz Au; $35/oz Ag; $4.75/lb Cu; $1.25/lb Zn

Net future cash flow (from 2011 and onwards) is undiscounted after tax and after all expansion and sustaining capex for 100% of the Bisha Project. Nevsun owns 60% of the Bisha Project and also has a receivable from the Eritrean State mining company related to its 30% purchased interest. The determination of the purchase price by a mutually appointed third party is in progress and is expected within the next month. The price is based on the feasibility study reserves and does not include any of the reserve increase noted above. The purchase price will be paid out of future cash flows from the Bisha Project.

Exploration & Development

Development of the project commenced in 2008.

At 2010 year-end plant construction was complete, with first gold pour taking place in late December. All significant facilities for operations were almost complete by the time the Company declared commercial production in February 2011.

The mine life is currently modeled for thirteen years however the Bisha deposit has been drilled to depths lower than the 200 meter currently modeled pit and mineralization has been identified as low as 380 meters and open beyond that depth. Accordingly it is the intention of the Company to further identify and quantify resources beyond the current pit with the goal of extending the life of mine well beyond thirteen years.

In addition, further exploration work is planned in the area to explore new targets within the 71 square kilometer Exploration License adjacent to the 39 square kilometer mining agreement area. The Exploration License includes the already identified Harena Zone deposit which was subject to an infill diamond drill program during the fourth quarter of 2010, the results of which were announced by news release in March 2011. A resource estimate has been initiated on the Harena Zone deposit and results are expected in Q2 2011. If the results are positive a reserve estimate and mine study will be done to support a Mining License application.
