the outcome of litigation matters and disputes in which we are involved;
government regulation of mining operations;
political risks and uncertainties;
general business and economic conditions; and
other events or conditions that may occur in the future.

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, assumptions and other factors, including, without limitation, the risks more fully described under the Section titled “Risk Factors” in Schedule B.

Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that could cause actual results to differ from what is anticipated, estimated or intended. 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. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. For the reasons set forth above, investors should not place undue reliance on forward-looking statements.

Cautionary Note to US Investors Regarding Disclosure of Mineral Reserves and Resource Estimates

The disclosure in this AIF uses mineral resource and mineral reserve classification terms that comply with Canadian securities laws that differ in certain material respects from the requirements of United States securities laws. Disclosure has been made 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. The NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. These standards differ significantly from the disclosure requirements of the SEC.

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. Consequently, mineral resource and mineral reserve information contained in this AIF is not comparable to similar information that would generally be disclosed by US companies in accordance with the rules of the SEC.

The SEC’s Industry Guide 7 applies different standards in order to classify mineralization as a reserve. As a result, the definitions of proven and probable reserves used in NI 43-101 differ from the definitions in Industry Guide 7. Under SEC standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Accordingly, mineral reserve estimates contained in this AIF may not qualify as “reserves” under SEC standards.

This AIF uses the terms “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” to comply with the reporting standards in Canada. The SEC’s Industry Guide 7 does not recognize these terms and US companies are generally not permitted to use these terms in documents they file with the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into SEC defined mineral “reserves.” Further, “inferred mineral resources” have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically.

Therefore, investors are also cautioned not to assume that all or any part of an inferred mineral resource exists. In accordance with reporting standards in Canada, estimates of “inferred mineral resources” cannot form the basis of feasibility or other economic studies, except in rare cases. In addition, disclosure of “contained ounces” in a mineral resource estimate is permitted disclosure

2 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

under NI 43-101 provided that the grade or quality and the quantity of each category is stated; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measures. For the above reasons, information contained in this AIF containing descriptions of mineral resource and mineral reserve estimates is not comparable to similar information made public by US companies subject to the reporting and disclosure requirements of the SEC.

General Development of the Business

Three Year History

The Company’s major achievements during the past three fiscal years include:

maintaining an industry leading safety performance record at Bisha;
the production of approximately 380 million pounds (172,300 tonnes) of copper since the commencement of copper production in mid-2013;
the production of approximately 784,000 ounces of gold in doré at Bisha from December 2010 through December 2013;
constructing both the copper and zinc expansion projects on time and under budget;
generating $913 million of after-tax operating cash flows since the commencement of commercial gold production;
continually replacing and increasing potentially available resources for the Bisha mill;
declaring and paying industry-leading dividends to shareholders; and
enhancing its corporate social responsibility programs.

As of the date of this AIF, construction of the zinc plant expansion is substantially complete and ore commissioning of the zinc plant is scheduled for late Q2 2016 at a projected cost of $80 million. The Bisha zinc expansion project is expected to average over 100,000 tonnes (225 million pounds) of zinc and 23,000 tonnes (50 million pounds) of copper per year for 9.5 years after commissioning in mid-2016.

2015 Significant Developments

In 2015, the Company produced 135.9 million pounds of copper in concentrate from the Bisha Mine at C1 cash costs of $1.31 per payable pound sold which lead to earnings and operating cash flows with year-end working capital of $462 million including $434 million in cash. The Company declared an annualized dividend of $0.16 per share, representing a fifth consecutive year of increased dividend declarations since the start of commercial production at the Bisha Mine in early 2011. The Company also advanced the zinc expansion project on time and under budget with construction completion and the start of ore commissioning scheduled for late Q2 2016.

Exploration drilling results at the Harena deposit during 2015 continued to demonstrate continuity of mineralization down dip and plunge and as a result, the Company announced revised mineral resources for Harena on February 17, 2016. Drilling at Harena added 0.5 million tonnes of indicated resource and 4.5 million tonnes of inferred resource. This brings the total indicated resource at Harena to 3.7 million tonnes (including in-situ 70 million pounds copper, 258 million pounds zinc, 70,000 ounces gold and 3.3 million ounces silver) and the total inferred resource to 11.0 million tonnes (including in-situ 348 million pounds copper, 952 million pounds zinc, 360,000 ounces gold and 14.4 million ounces silver). The deposit remains open at depth with the grade and thickness of the massive sulphides increasing in the deepest tier of exploration holes.

In Q2, the Company announced the discovery of a new massive sulphide deposit at the greenfield Asheli prospect on the Mogoraib River Exploration License located 20 kilometres southwest of the Bisha processing plant. Highlight drill holes include:

MX-052 which graded 2.29% Cu, 4.50% Zn, 0.45 g/t Au, 37 g/t Ag over 22.9 metres, including 3.67% Cu, 8.04% Zn, 0.68 g/t Au, 50 g/t Ag over 7.4 metres and 7.92% Cu, 3.89% Zn, 1.14 g/t Au, 101 g/t Ag over 2.9 metres
MX-056 which graded 1.26% Cu, 6.08% Zn, 0.28 g/t Au, 26 g/t Ag over 20.9 metres including 1.71% Cu, 8.51% Zn, 0.37 g/t Au, 35 g/t Ag over 10.9 metres.

The deposit is associated with highly altered felsic volcanics and is open to expansion with numerous untested geochemical and geophysical targets occurring along at least 4 kilometres of similar stratigraphy.

It also paid a quarterly dividend of $0.04 per share and monetized stockpiled precious metals concentrate.

The Company also provided an update on its human rights record in response to media speculation and reported that it commissioned an independent human rights impact assessment (HRIA) in 2013 which was completed in and published in April 2014 with cooperation from the State of Eritrea.

At its 2015 annual general meeting, the Company received strong support from its shareholders for the election of NRL’s nominees as directors as well as its approach to executive compensation and ratification of the stock option plan.

In the first quarter the Company announced that it earned $0.06 per share, generated $37 million in cash and produced 38 million pounds of copper in concentrate at C1 cash costs of $1.23 per payable pound sold which lead to earnings and cash flows with quarter end working capital of $517 million including $443 million cash. It also paid a quarterly dividend of $0.04 per share and continued with progress of the zinc plant expansion on time and on budget.

The Company released its 2014 Corporate Social Responsibility Report in April highlighting its safety record, community engagement efforts and local employment, successful environmental management and practices, and progress on independent human rights impact assessment follow-up recommendations in training and development.

In the first quarter, the Company announced a restart of operations at the Bisha Mine after completing repairs to the ball mill and tailings thickener. During the temporary shutdown which lasted less than two weeks, the Company completed additional preventative plant maintenance which was scheduled in the second quarter, repairs to the damaged base of the tailings thickener during the shutdown period and upgrades to 10 of the 27 thermal power diesel generators by Aggreko. Waste mining was conducted during the shutdown period.

On February 3, 2015 the Company announced the updated mineral resource estimate effective December 31, 2014 for the Bisha and Harena deposits. The Bisha primary indicated resource grew by 0.9 million tonnes and primary inferred resource grew by 0.6 million tonnes. This primary zone growth added indicated resources of 83 million pounds of zinc and 40 million pounds of copper, and inferred resources of 96 million pounds of zinc and 21 million pounds of copper. The Harena open pit indicated resource grew by 1.4 million tonnes adding 113 million pounds of zinc and 32 million pounds of copper, and primary inferred resources increased by 6.1 million tonnes for an addition of 408 million pounds of zinc and 156 million pounds of copper.

2014 Significant Developments

In 2014, the Company produced 196 million pounds of copper in concentrate from the Bisha Mine against guidance of 180 million to 200 million pound at C1 cash costs of $1.05 per payable pound sold which lead to earnings and cash flows with year-end working capital of $520 million including $442 million in cash.

The Company conducted a 27,300 metre drilling program and progressed zinc plant expansion on time and on budget.

8 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

In the fourth quarter the Company produced 52.5 million pounds of copper in concentrate at C1 cash costs of $1.07 per payable pound sold.

The Company conducted significant exploration drilling at the Harena Mining License as part of an on-going program designed to expand the deposit beyond the known resource. The drilling program successfully extended the deposit by 250 metres down dip and increased the strike length from 300 metres to over 600 metres. Highlight drill holes include massive sulphides intersected in the southern extension discovery hole HX-005 which graded 1.77% Cu, 3.99% Zn, 1.22 g/t Au, 78 g/t Ag over 18.5 metres and hole HX-040 which graded 1.78% Cu, 5.78% Zn, 0.53 g/t Au, 31 g/t Ag over 32.0 metres. Borehole geophysics suggests that Harena has considerable further down dip extension potential. Also intersected were a number of precious metal-bearing stringer zones found below and along strike of the massive sulphides such as hole HX-008 which returned 0.71% Cu, 0.22% Zn, 6.15 g/t Au, 242 g/t Ag over 17.2 metres.

The Company issued an updated mineral resource and mineral reserve estimate effective December 31, 2014 for the Bisha and Harena deposits. The Bisha primary indicated resource increased by 0.9 million tonnes, adding 83 million pounds of zinc and 40 million pounds of copper, and primary inferred resource increased by 0.6 million tonnes, adding 96 million pounds of zinc and 21 million pounds of copper. The Harena pit indicated resource increased by 1.4 million tonnes, adding 113 million pounds of zinc and 32 million pounds of copper, and primary inferred resources increased by 6.1 million tonnes for an additional 498 million pounds of zinc and 156 million pounds of copper.

In 2014 the Bisha supergene reserve, inclusive of stockpiles, decreased by 3.9 million tonnes, which included 295 million pounds of copper. Of this reduction, approximately 1.8 million tonnes and 230 million pounds of copper were due to mine depletion. The remaining reduction of 2.1 million tonnes and 65 million pounds of copper came from reclassification of supergene to primary ore, removal of the hanging wall copper ore pending further metallurgical testwork, pyrite sand displacement and elevated operating costs. Conversely, this reclassification and a deepening of the Bisha Main pit, lead in part to the Bisha primary reserve increasing by 1.7 million tonnes including an increase of 91 million pounds of copper and 270 million pounds of zinc. The Harena primary reserve increased by 0.3 million tonnes including 8 million pounds of copper and 26 million pounds of zinc.

In the third quarter the Company produced 56.4 million pounds of copper in concentrate at C1 cash costs of $1.07 per payable pound sold which lead to earnings and cash flows with quarter end working capital of $519 million including $380 million cash.

In the second quarter the Company produced 47.4 million pounds of copper in concentrate at C1 cash costs of $1.05 per payable pound sold which lead to earnings and cash flows with quarter end working capital of $498 million including $359 million cash.

The Company received strong support at the 2014 annual general meeting for the election of NRL’s nominees as directors as well as its approach to executive compensation and the continuation of the shareholder rights plan.

In the first quarter the Company produced 39.7 million pounds of copper in concentrate at C1 cash costs of $0.98 per payable pound sold which lead to earnings and cash flows with quarter end working capital of $462 million including $338 million cash.

The Company released its 2013 Corporate Social Responsibility Report highlighting its safety record, local employment opportunities and evolving environmental and social performance governance programs at the Bisha Mine aimed at reinforcing NRL’s commitment to making a collaborative, positive impact in Eritrea.

The Company filed the 2013 Technical Report in March 2014.

The Company announced maiden open pit mineral resource estimates on February 18, 2014 for Hambok and the Northwest deposits for a combined 92 million pounds copper and 60 million pounds zinc and an updated mineral reserve estimate for the Bisha Main pit and Harena open pit mines. This resulted in a 29% increase in the total indicated mineral resource estimate of the combined Bisha property tenements by an additional 9.3 million combined oxide gold, supergene copper and primary copper-zinc zone tonnes

ANNUAL INFORMATION FORM – December 31, 2015

which resulted in an additional 247 million pounds of in-situ copper for a 22 percent increase in contained copper and an additional 47 million pounds of in-situ zinc.

2013 Significant Developments

The Company achieved commercial production of copper on December 1, 2013 from its copper plant on schedule and under budget with a build cost of the copper plant and infrastructure at approximately $110 million, compared to a budget of $125 million.

In 2013, the Company produced 92,000 ounces of gold doré plus 20,000 equivalent gold ounces in precious metal concentrate from the Bisha Mine. The Company also produced 48 million pounds of copper in concentrate against guidance of 30 million to 50 million pounds, which lead to strong earnings and cash flows with year-end working capital of $419 million including $303 million cash.

The Company conducted an eight-hole 2,713 metre in-fill resource definition drilling program at the Hambok polymetallic massive sulphide deposit, located 16 kilometres southwest from the BMSC processing plant.

The Company also conducted a 4,325 metre resource definition drilling program at the Northwest deposit for an aggregate of 15,890 metres of drilling completed which includes 13,520 metres of drilling that was completed in 2011 and 2012.

In 2013, NRL declared two cash dividends of $0.07 per common share on May 15, 2013 and November 14, 2013 which were paid to shareholders on July 15, 2013 and January 15, 2014, respectively. Dividends declared in 2013 totalled $27.9 million.

On October 15, 2013, the Company announced the first shipment of 11,000 tonnes of pre-commercial production copper concentrate from the new Bisha copper plant. Commissioning and ramp up in mill throughput continued with commercial production achieved on December 1, 2013.

The Company released its 2012 Corporate Social Responsibility report. The report was written and released under the Global Reporting Initiative’s G3.1 guidelines and self-declaring Application Level C.

The Company commented on its approach to human rights at the Bisha Mine and committed to responsible operations and practices at the Bisha Mine, based on international standards of safety, governance and human rights.

The Bisha Mine, located on the Bisha Property, is owned and operated by BMSC. The Company is a 60% shareholder in BMSC with the remaining 40% interest held by ENAMCO. BMSC is governed under the terms of a shareholder agreement between the Company and ENAMCO. The Bisha Mine began commercial production of gold in February 2011 that allowed an early payback of gold phase capital and allowed for complete funding of both the copper and current zinc phase expansion. The Bisha Mine transitioned from gold production to copper production in late H2 2013 and commenced commercial production of copper in December 2013. The development of the zinc flotation circuit required for future zinc production is expected to be online in late Q2 2016. Mining of the supergene copper ore is expected to continue until late Q2 2016 at which time the Bisha Mine plans to begin to process ore from the primary phase. The primary phase ore contains a significant amount of zinc and copper. Construction of the zinc plant began in 2014 with the zinc plant scheduled for ore commissioning scheduled for late Q2 2016 with objective to achieve commercial production three months later.

Copper, Gold and Silver Sales

The Company recorded revenues of $357 million based on sales of 139 million pounds of payable copper in 2015 compared to 2014 revenues of $555 million based on sales of 185 million pounds of payable copper.

There are numerous customers of copper, and zinc concentrates which include by-product gold and silver revenues, as well as for the stockpiled gold material. Accordingly, the Company is not dependent upon any one customer. Copper and zinc concentrates are produced at site and transported in country by truck and trailer to the port of Massawa and in turn loaded into ocean freighters for transport to smelters in Europe and Asia.

Methods of Production

The Company began processing supergene copper ores in 2013 using flotation to recover copper as a sulphide concentrate and will use the same process when primary copper and zinc ores are processed starting in late Q2 2016.

The current open pit mine life is estimated to be 9.5 years, projected to 2025, including three to six months of final processing of remnant oxide ores producing gold doré in the final year of mine life using the original carbon-in-leach circuit. The Company continues with its efforts to expand mineral resources with ongoing exploration drilling programs with an expectation of subsequent conversion into mineral reserves. The Company has been conducting ongoing drilling programs on the Bisha and Harena Mining licenses and on the Mogoraib River Exploration License with the plan to further extend the life at the Bisha Property. Exploration on the Bisha and Harena Mining licenses has focussed mainly on expanding the known deposits, while work on the Mogoraib River license is entirely directed at discovering new deposits. Many untested geophysical targets remain on these properties and new targets are being generated which will be evaluated with future drilling. This exploration work has a high potential to provide significant additional near and long-term mineral resources for the Bisha operations.

Skill and Knowledge

BMSC has built a management team of skilled mining, processing, maintenance, environmental, financial, and administrative personnel reporting to the general manager at the Bisha Mine who is in charge of mine production, process plant facilities and exploration programs. The specialized knowledge and skills required in all areas of mining include mining, engineering, geology, metallurgy, environmental permitting, drilling, and exploration program planning. The Bisha Mine is the first modern mining operation in Eritrea. Training and re-training of local staff to attain and maintain the requisite skills in all aspects of mining operations remains a priority.

Employees

BMSC directly employs approximately 1,100 Eritreans and 130 expatriates at the Bisha Mine and provides a safe and supportive working environment. After commissioning of the zinc flotation plant, the number of expatriates is expected to reduce to about 100 by the end of 2016. The Company strives to ensure that its presence has a positive social and economic impact. With spin-off effects from local suppliers for certain goods and services required the Bisha Mine has created meaningful employment for thousands of Eritreans. Compensation for Eritreans directly employed by BMSC is well above the average wage in Eritrea. Employees are provided free food and free accommodations or free local commuting. These employees also receive free training and have opportunities for advancement. Employees also have access to free medical care at the mine’s clinic. The use of conscripted labour at Bisha is not allowed, and BMSC has strong practices and procedures to ensure that all individuals at Bisha have been released from National Service requirements of the Eritrean government. The procedures include the inspection of national service discharge documentation for all Eritrean workers at Bisha.

Mineral Properties

The Company’s principal mineral property is the Bisha Property located in Eritrea which hosts the Bisha Mine. The property is owned and operated by BMSC which in turn is controlled 60% by the Company and 40% by ENAMCO. BMSC is governed under the terms of a shareholder agreement between the Company and ENAMCO. Under Eritrean Mining Law, ENAMCO initially held a 10% free carried interest in BMSC. In October 2007, ENAMCO agreed to purchase an additional 30% interest in BMSC, the terms of which were finalized in 2011. In December 2007, BMSC concluded a Mining Agreement with the State of Eritrea. Royalties payable to the State of Eritrea include a 5.0% royalty on precious metals and a 3.5% royalty on base metals.

The Bisha Mine on the Bisha Property began commercial production in February 2011 with approximately 784,000 ounces of gold in doré being produced from oxide mineralization until late 2013. In December 2013, the Bisha Mine achieved commercial production of copper derived from supergene mineralization. The Company will be transitioning to production of copper and zinc from the primary zone beginning in late Q2 2016. Construction and commissioning of a zinc flotation circuit required for future zinc production from the primary sulphide zone remains on schedule for ore commissioning in late Q2 2016 at a projected cost of $80 million.

Accessibility, Climate, Local Resources, Infrastructure & Physiography

Access to the Bisha Mine is by paved road from Asmara to Akurdat, a distance by road of 181 kilometres and then 52 kilometres from Akurdat via an all-weather road which is currently being upgraded with over 30 kilometres now paved. The drive from Asmara to the Bisha camp (also referred to as Bisha Village) takes approximately four to six hours by passenger vehicle or bus. Asmara is the capital city of Eritrea and is serviced currently by regular international flights out of Cairo, Doha, Dubai and Istanbul.

The principal port for importation of heavy equipment and shipment of concentrate is Massawa on the Red Sea coast which is about 350 kilometres from the Property. Massawa is connected to Asmara by all-weather paved road. The Company has a special loading system to accommodate the handling and bulk loading of both copper and future zinc concentrates onto shipping vessels.

The climate is semi-arid, with elevated temperatures year-round. During the hot season in April and May, the average temperature is +42°C. Total annual rainfall is sparse, with between 250 millimetres and 300 millimetres. The main rainy season is between June and September and local heavy rains can result in flash floods of the Mogoraib and Barka Rivers. Mining activities are planned on a year-round basis.

The Bisha Property is mainly located on a flat, desert-like outwash plain. The plain is at 560 metres above sea level and contains scattered vegetation and few trees. Locally, steep hills and ridges rise above the plain with the Bisha, Wade, and Neve peaks reaching elevations of up to 1,226 metres above sea level.

16 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

The Bisha Property is crosscut by the Mogoraib River, a tributary of the Barka River, as well as seasonal streams that all flow northwards. A small seasonal tributary of the Mogoraib River, the Ferektatet River, originally passed immediately over the Bisha Property but has since been diverted around the deposit.

The village of Mogoraib located 6 kilometres from the Bisha Mine is the closest settlement and is the local administration centre for the Dighe Sub-zone within the Gash-Barka District. The village contains a well-equipped, eight-person health centre with a nursing staff capable of taking care of small medical problems. Better-equipped hospitals are found in Akurdat and Keren. Camp Mogoraib is a military site located just outside the village boundaries and provides basic security to the Mine area. Basic goods are commercially available in the immediate region near the Bisha Mine at Mogoraib or Akurdat, but the main centre for support is the capital city of Asmara.

Freshwater is supplied to the property from groundwater. Two well farms have been established by the Company, the first approximately 1 kilometre south of the open pit on the western bank of the Ferektatet River (which also serves to dewater the Bisha pit), and the second, 5 kilometres to the west, adjacent to the Mogoraib River. Potable water sourced from the well fields is pumped to a potable water plant utilizing chlorination filtration and ultraviolet radiation treatment.

Process water is recycled within the plant as much as possible to minimize the use of fresh groundwater. Water from the pit and seasonal water from the tailings management facility will be treated in a water treatment plant to be completed in H2 2016 to supplement and reduce the dependence on raw water.

Electric power for the mine and processing plant site is supplied from a diesel-fuelled power station located adjacent to the process facilities. Site communication is via a satellite communications system and includes wireless internet access at the village and administration buildings.

Mineral Property History

The Company has no record of any previous exploration or mining activities on the property or surrounding areas prior to 1998. In June 1998, the Company signed a prospecting license agreement with the State of Eritrea. In 1999, this agreement was converted to an exploration license that covered an area of 49 square kilometres. This license was expanded to an area of 224 square kilometres in 2003.

Geological Setting

Eritrea is divided into several north or northeast trending Proterozoic terranes which are separated by major crustal sutures. The Bisha Property is in the Nacfa Terrane which comprises low-grade metamorphosed calc-alkaline volcanics and sediments.

The VMS deposits at the Bisha Property are hosted by a bimodal sequence of volcanic rocks. Felsic volcanics directly host and both underlie and overlie the mineralization at Bisha, Harena and Northwest deposits. These felsic volcanics are flow dominated indicating proximity to volcanic vents. Mafic volcanic rocks occur deeper in the footwall to the east of the known mineralized zones. Alteration of the felsic volcanics is often very intense with the primary mineralogy being converted to sericite and chlorite. The Hambok deposit, in contrast to the Bisha deposits, is entirely hosted in mafic volcanic rocks. All rock-types are variably foliated and metamorphosed.

Exploration History

Initial work on the property began in 1998 but was suspended between 1999 and late 2002 due to the border war with Ethiopia. The Bisha deposit was discovered in November 2002 by diamond drilling geophysical and geochemical anomalies associated with a prominent gossan that locally had highly anomalous gold values. A VMS deposit was defined and found to be overlain by a supergene copper-enriched zone and a gold-enriched gossan cap.

Between 2003 and 2006, 403 diamond drill and 33 reverse circulation holes were completed at Bisha to enable a Feasibility Study. Additional work included mapping, geochemical sampling, trenching, ground and airborne geophysics, metallurgical test work and environmental baseline studies. The Northwest and Harena deposits were discovered with 26 and 27 holes being drilled respectively.

17 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

No holes were drilled in 2007 and 2008 and only minor gravity surveying, geological mapping and mechanical trenching were completed. In 2009 and 2010, 35 mainly geotechnical holes were completed at Bisha and 51 holes were completed at Harena to better define the oxide zone. Thirteen diamond drill holes were drilled to test gravity targets in the Harena area. No significant mineralization was intersected.

In 2011, 167 diamond drill holes were drilled at Bisha for resource upgrading as well as for metallurgical and geotechnical studies. At Harena, 5 regional exploration holes were drilled to test coincident gravity/EM/soil geochemical anomalies with no significant mineralization being encountered. Drilling began to define the Northwest deposit to bring it to a maiden resource estimate. A total of 22 holes were drilled.

In 2012, the majority of drilling was focussed on the development of the Northwest deposit. Seventy-five holes were drilled to define a maiden resource. At Harena, exploration diamond drilling included a total of 6 holes with one of the holes intersecting mineralization peripheral to the Harena open pit.

In 2013, diamond drilling consisted of 27,828 metres of exploration and resource development drilling at Bisha Main, the Northwest deposit and Hambok. At Bisha, 23 holes for 6,223 metres were completed in the immediate Bisha area testing geophysical targets. A further 8 holes tested below the northern portion of the Bisha Main deposit. Drilling concluded at Northwest with 93 holes being completed. At Hambok, eight holes were completed to infill areas of the deposit that had large gaps in the geological model. This work allowed for a new open pit constrained mineral resource estimate to be completed.

In 2014, a total of 91 drill holes were completed at Bisha and Harena, around Hambok and Aderat and near Tekewuda to complete 27,300 metres of exploration diamond drilling. A total of 230 line kilometres of ground and 44 holes of Transient EM surveying was conducted and a 2,500 line kilometre Versatile Transient Electromagnetic survey was flown. A significant new extension of the Harena deposit was discovered and new mineralization was found at Aderat on the Mogoraib River Exploration License.

For 2015, a total of 35,805 metres of exploration diamond drilling (72 holes), approximately 30 square kilometres of ground geophysical surveying, geophysical surveying of 85 drill holes and other geological work was completed. Drilling at Harena continued to be successful and the deposit was further defined at depth where it remains open to further expansion. In the immediate Bisha Mine area, exploration efforts were ramped-up, testing for extensions to the main pit deposit both along strike and at depth. Exploration on the Mogoraib River License resulted in the discovery of the Asheli deposit in mid-2015. Drilling was suspended as per usual practice due to the annual rainy season in Q3 and no further drilling was completed. However, further geological work resulted in the definition of new targets along strike and to the east of Asheli which will be tested in 2016. Further drilling was also completed at the Aderat prospect which was discovered in 2014. This drilling has defined new targets which will be tested in the future.

Mineralization

Mineralization at the Bisha deposit is divided into three major zones: oxide, supergene and primary sulphide. The host rocks are felsic volcanics that have been altered to chlorite and sericite.

Oxide

In the surficial oxide zone, deep weathering has affected the primary massive sulphides producing a high-grade stratified gossanous zone that is enriched in gold. This zone can vary in composition from highly siliceous and somewhat ferruginous to a massive goethite-hematite-jarosite. The depth of this oxidation zone was on the order of 35 metres. The oxidation of the massive sulphides generated strong acid solutions that have progressively destroyed the sulphides and host rock. Gold remained in the oxide zone and became concentrated. This zone is now largely mined-out.

Supergene

As the acid solutions percolate downward, they deposited their dissolved copper at the primary sulphide interface to produce a copper-rich supergene zone. A horizon of extremely acid-leached material or “soap” was developed between the oxide and supergene/primary domains and the host rocks. The principle copper mineral in the supergene zone is covellite. This zone is currently being mined with majority excavated by mid-2016.

18 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

Primary Sulphide

This zone is a typical VMS with simple pyrite, chalcopyrite and sphalerite mineralogy in the massive sulphide and chalcopyrite in the stringer zones. Mining and stockpiling of primary zinc ores commenced in March 2014 and by the end of the 2015 year, stockpiles of 980,000 tonnes of zinc ore formed part of the stockpile inventory.

The Harena deposit is also a typical massive sulphide body that has been affected by weathering. The host rocks to the Harena deposit are intensely chloritized and sericitized hydrothermally-altered felsic volcanic rocks. Surficial weathering processes have produced a surficial oxide/gossan zone with good gold grades underlain by a primary massive sulphide deposit. Supergene mineralization is not well developed. The primary massive sulphide body is currently being explored and is mainly composed of pyrite, chalcopyrite and sphalerite. Chalcopyrite rich stringer zones occur stratigraphically beneath the massive sulphides, some of which have high precious metal contents.

The Hambok deposit consists of a single massive sulphide lens. Base metal values are generally higher nearer to surface along the top and outer edges of the body. The deposit is hosted by variably chloritized mafic volcanic rocks and is dominantly composed of massive pyrite with zones of finely banded chalcopyrite and sphalerite. Intervals of near massive magnetite are often found associated with the massive sulphides.

Mineralization at the Northwest Zone occurs in a series of predominantly pyrite massive sulphide lenses hosted within altered felsic volcanic rocks. Copper and zinc-rich stringer sulphide mineralization is sporadic within the massive sulphide lenses and in stockwork zones. Some of the massive sulphides have been exposed to weathering at surface creating oxide zone that are locally enriched in gold. Beneath these areas, some supergene copper mineralization may also be present.

Drilling

Diamond drilling at the Bisha, Harena, Northwest and Hambok deposits has been undertaken by contractors in a number of campaigns since 2002, with Boart Longyear and Colonnade being the most recent suppliers in 2014 and 2015. For drilling prior to 2014, please refer to the 2013 Technical Report.

In 2015, drilling was completed using Longyear LF90 track mounted drill rigs. Holes are typically initially collared HQ size diameter and reduced to NQ size diameter after approximately 75 metres. In difficult ground conditions, PQ size diameter may also be used to start holes until the broken ground conditions improve and the hole can be reduced to HQ size diameter. All drill hole collars are surveyed and down-the-hole surveys were completed with Reflex EZ-Shot camera methods.

At the Bisha Main deposit, massive sulphide mineralization has been well defined with drilling spaced at 25 metres by 25 metres or closer in some areas. Drilling density decreases with depth and the deposit is open at depth in the south.

At the Harena deposit, massive sulphide mineralization was drilled on a 30 metre by 50 metre pattern prior to 2014. During 2014, drilling down to a depth of 200 metres was on a 50 metre by 50 metre pattern while deeper holes were on a 100 metre by 100 metre pattern or wider. The deposit is open at depth.

At the Hambok deposit, much of the massive sulphide mineralization has been well defined with drilling spaced at 50 metres by 50 metres or closer in some areas. Drilling density decreases with depth and the deposit remains open at depth and along strike to the north. No drilling was completed at Hambok in 2015.

At Northwest, the deposit is well defined with drilling spaced at 25 metres by 25 metres or closer in some areas. Drilling density decreases with depth and the deposit is open in a number of directions. Core recovery problems in the oxide zone and supergene zone were countered by classification of this material as Inferred Resources. No drilling was completed at Northwest during 2015.

Sampling and Analysis

For sampling programs prior to 2014, please refer to the 2013 Technical Report.

For 2014 and 2015, holes were nominally sampled over all sulphide-bearing intervals at a target length of 1.0 metre per sample which was reduced to 0.5 metre per sample to better understand the metal zonation. Sample intervals vary based upon mineralogical and lithological contacts. The logging geologist sets out the sample regime. Standard diamond cutting blades flushed with fresh water are used to halve the core.

Highly broken core pieces are cut along the axis if possible or the core is split using a trowel down the middle of the tray row and handpicked or scooped to ensure representative samples are obtained. Cutting lines may be drawn on the core. The remaining half core is returned to the box and boxes stacked in numerical order by hole.

The technicians or samplers under the supervision of technicians place half of the core in individual trays laid out in numerical order. Samples are then placed in a drying oven for 12 to 18 hours at between 80°C and 100°C. The samples then pass through a jaw crusher to greater than 75% of sample passing 10 mesh (2 millimetre) screen. The sample is then split using a Jones-type riffle splitter to achieve a sub-sample weight of approximately 200 to 300 grams. The sample reject is then bagged, labelled with the original sample ID and put into storage at Bisha site. The sub-samples are pulverised to better than 85% passing 75 microns. When ready for shipping, the pulps are then dispatched by courier in twenty litre sealed plastic pails along with a sample list and sample submission form to the Genalysis laboratory in Perth, Western Australia for analysis.

Bulk density for all samples is determined using Archimedes principle. Rock samples are dried and then wrapped in foil prior to weighing in air and water.

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 Bisha personnel and placed in the core logging area.
The logging and sample preparation area and the Bisha camp are within a fenced and guarded compound.
Core samples are crushed, sub-sampled and pulverized.
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 managed by BMSC.

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 the analytical laboratories.

Mineral Resource Estimate

Commencing in 2005, an initial mineral resource model for Bisha Main was constructed by AMEC. This model was subsequently updated with new information. In 2012, AGP, an independent mining and geological consulting firm that had not previously reported on the property, estimated an updated mineral resource at Bisha. In 2012, AMEC estimated a mineral resource at Harena. In August 2012, AGP Mining Consultants Inc. prepared a new combined Bisha and Harena mineral reserves estimate with an effective date of May 31, 2012 with a technical report which was subsequently filed on SEDAR and EDGAR.

In late 2013, new revised updated mineral resources were estimated with an effective date of December 31, 2013 for both the Bisha Main and Harena deposits which took into effect mine depletion, additional drill, structural mapping and metallurgical test data, and a more refined and slightly differing approach to mineral resource modeling. Likewise, an updated mineral resource estimate was generated for the Hambok deposit succeeding the past historic mineral resource generated by the previous owner Sanu Resources which importantly employs a constraining pit shell. In addition, a maiden mineral resource

20 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

estimate was completed for Northwest. Details and methodology of this mineral resource estimate can be viewed more fully in the 2013 Technical Report.

Subsequent to the 2013 Technical Report, the resources for both Bisha Main and Harena were estimated by independent consultants Cube Consulting with an effective date of December 31, 2014.

The current mineral resource effective December 31, 2015 was completed for the Bisha Main and Harena deposits by BMSC and announced on February 17, 2016. At Bisha, an additional 2,819 metres of diamond drilling was completed in 2015 and these extended the mineralisation approximately 80 metres down-plunge; some adjustments to the mineralisation interpretations were made that reflected the experience gained from open pit mining.

At Harena, 20,308 metres of new drilling in 2015 led to an improved understanding of the geology and mineral zonation used in the resource estimation process, as well as extending the resource approximately 400 metres down-plunge. Drilling also indicated that the mineralisation is open at depth.

The sample database for the Bisha, Harena, Northwest and Hambok deposits has undergone a thorough QA/QC process. The current interpretation and estimation for Bisha was completed using diamond drilled cored holes and recent RC grade control holes. The majority of the RC holes were drilled as part of a grade control program for the supergene copper phase beginning in 2013 while almost all the diamond drilled holes were drilled prior to May 2012. Diamond drill data for the Northwest and Harena deposits include a significant proportion of drilling completed from 2012 onwards. All data for Hambok acquired from Sanu Resources was validated before being used.

Indicated resources at Harena grew due to infill drilling by 480,000 tonnes or 15% from the previous year adding 12 million pounds of copper, 20 thousand ounces of gold and 560 thousand ounces of silver, offset by zinc indicated resources decreasing slightly by 10 million pounds. The inferred resources at Harena were increased by the additional drilling of the down-plunge extension which added 4.5 million tonnes or 69% from the year earlier for an additional 186 million pounds of copper, 423 million pounds of zinc, 230 thousand ounces of gold and 6.47 million ounces of silver. In-situ metal grade estimates in the inferred resource category also increased as contained copper grew by 115%, zinc by 80%, gold by 177% and silver by 82%.

Despite the lower commodity prices used in 2015 for NSR calculations as compared with 2014, the measured and indicated resource at Bisha remained essentially unchanged from the year previous while the inferred resource decreased slightly by 0.30 million tonnes. The Bisha measured and indicated resources of contained zinc, gold and silver increased by 5%, 11% and 11% respectively; the 25% reduction in copper was mainly due to mining depletion of the supergene zone.

Bulk density values were assigned on the basis of rock type and oxidation state, as defined by the interpreted geological wireframes. The values are based on a combination of bulk densities from the previous resource estimate and in-situ measurements in use at the mine derived during mining.

For all deposits, the estimation process involved the creation of 3D geological and mineralization shapes from interpreted cross sections, statistical domaining, flagging of database, compositing of samples, variography, and estimation of grades by ordinary kriging using search parameters optimized by kriging neighbourhood analysis. Each domain was separately estimated using the unique set of composite samples associated with that domain.

Visual and statistical validation of the copper, zinc, lead, gold, and silver grade estimates for Bisha demonstrate that the model is a reasonable representation of the input data. A comparison of the copper supergene estimate to actual production to date also demonstrated that the model is a good predictor of production.

The mineral resource for all deposits is a global estimate representing a reliable estimate of the total contained metal at the applied cutoffs, but the block estimates are likely to vary significantly compared with the actual grade/tonnage distribution that will be achieved during selective mining and over short production periods; this variability was considered when applying resource classifications.

The mineralization at each deposit has been sufficiently drilled and sampled to allow classification as a combination of Measured, Indicated or Inferred Mineral Resource in accordance with the current CIM Definition Standards for Mineral Resources and Mineral Reserves. The classification employed reflects a practical combination of both geological knowledge and estimation quality parameters that may be more

numerical in nature. This approach to classification aims to avoid creating a complex classification system.

Reasonable prospects for economic extraction were made by applying an NSR-based cutoff to blocks within a constraining optimized pit shell using Lerchs-Grossmann optimization.

The assumed long-term metal prices used for the optimization work as applied to Mineral Resources are shown in the footnotes of the mineral resource tables below. These metal prices are approximately 15% higher than those used in the estimation of Mineral Reserves.

The NSR calculation and pit optimization process considers many of the parameters used in the mineral reserve estimation, as these parameters are well established within the working mine. These parameters include commodity price, budget costs for production and processing, process recoveries, concentrate grade, selling costs, and other ore-based costs. The optimization process also uses the current geotechnical model for the pit design.

For the Bisha and Harena deposits, mineralization below the pit shell described above was studied for potential for underground mining. A high-level study in 2013 concluded that an appropriate underground mining cost per tonne would be $60/t. The mineralization was then analyzed for contiguous blocks with NSR values exceeding $100/t. A shape of sufficient tonnage and value was identified, and this tonnage is included in the Inferred Resource category given in the Mineral Resource statement.

The following tables are based on the December 31, 2015 mineral resource statement, as certified by the identified QPs as of the effective dates indicated. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral Resources reported here for Bisha and Harena are inclusive of Mineral Reserves.

Bisha and Harena notes to be read in conjunction with the Resource tables above:

(1)

Mineral Resources are defined within an optimal LG pit shell, generated using metal prices for copper, zinc, gold and silver of $3.15/lb, $1.10/lb, $1,265/oz and $21/oz respectively using blocks of all Resource categories. The mining cost and total ore based cost (process, G&A and stockpile rehandle) applied was approximately 10% below the long term view on costs with appropriate ore haulage costs for each satellite deposit. Overall pit slopes varied from 31 deg to 44 deg for Bisha and 29 deg to 44 deg for Harena NSR cut-off ($US/t) used were:

Bisha: $37.50 for Oxide Phase; $37.00 for Supergene and $38.50 for Primary Phase.

Harena: $40.00 for Oxide Phase and $41.00 for Primary Phase.

(2)	Net Smelter Return values were calculated for each block using all resource categories, metal prices, recoveries, appropriate smelter terms and downstream costs. Metallurgical recoveries, supported by metallurgical test work, were applied as follows:

Bisha oxide zone: recoveries of 88% and 22% were applied for gold and silver respectively.

Harena oxide zone: a recovery of 75% and 22% were applied for gold and silver respectively.

Bisha Supergene zone; recoveries of 83.3%, 55.5% and 70% were applied for copper, gold and silver respectively.

Bisha Primary zone; recoveries to copper concentrate of 85%, 36% and 29% were applied for copper, gold and silver respectively. Recovery to zinc concentrate of 83.5% was applied for zinc.

Harena primary zone; recoveries to copper concentrate of 85%, 36% and 29% were applied for copper, gold and silver respectively. A zinc recovery to zinc concentrate of 72% was applied.

(3)

Mineral Resources are reported within the pit shell generated using the specified commodity prices, using NSR block grade cut-off derived as above. Tonnage is rounded to the nearest 10,000 tonnes and grades are rounded to two decimal places for copper and zinc, one decimal place for gold and zero decimal places for silver. Tonnages and grades for the Inferred category are further rounded reflecting the uncertainty that attaches to this category. Contained metal for copper and zinc are rounded to the nearest million pounds for Bisha and Harena.

(4)	Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade and contained metal content.

(5)	Tonnage and grade measurements are in metrics units. Contained gold and silver ounces are reported as troy ounces, contained copper and zinc pounds as imperial pounds.

(6)	Stockpile tonnages are included in the total given in the tables for Bisha and Harena, with their resource category generally reflecting the underlying resource category from which they were derived.

(7)

Both the Bisha and Harena Primary Inferred Resources include an Underground Resource. These were derived by defining a shape around contiguous blocks outside the optimized resource pit shell, where an overall NSR of $100 was achieved. The value of NSR $100 represents the processing cost plus approximately $60/t mining cost.

(8)	Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

Hambok and Northwest notes to be read in conjunction with the Resource tables above:

(1)

No change has occurred to Hambok and Northwest since 2014 which used metal prices for copper, zinc, gold and silver of $3.35/lb, $1.05/lb, $1,350/oz and $23/oz, respectively. Mineral Resources are defined within an optimal Lerchs-Grossman (LG) Pit Shell. The mining cost and total ore based cost (process, G&A and stockpile rehandle) applied was approximately 10% below the long term view on costs with appropriate ore haulage costs for each satellite deposit. Overall pit slopes varied from 39 to 45 for Northwest and 40 overall for Hambok (preliminary assessment). NSR cut-off ($US/t) used were:

26 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

Northwest: $40.70 for Oxide Phase, $39.70 for Supergene and Primary Phase.

Hambok: $44.45 for Oxide Phase and $43.45 for Primary Phase.

(2)	Net Smelter Return values were calculated for each block using all resource categories, metal prices, recoveries, appropriate smelter terms and downstream costs. Metallurgical recoveries, supported by metallurgical test work, were applied as follows:

Northwest oxide zone; recoveries of 88% and 22% were applied to gold and silver respectively.

Northwest Supergene zone; recoveries of 87%, 46% and 50% were applied for copper, gold and silver respectively. Zinc has not been assigned a recovery as the values are isolated on the fringes of the deposit.

Northwest Primary zone; recoveries to copper concentrate of 87%, 36% and 29% were applied for copper, gold and silver respectively. Recoveries to zinc concentrate of 81%, 36% and 29% were applied for zinc, gold and silver respectively.

Hambok oxide zone; recoveries of 88% and 22% were applied to gold and silver respectively.

Hambok; recoveries to copper concentrate of 88%, 87%, 36% and 29% were applied for copper, zinc, gold and silver respectively. Preliminary metallurgical characterization studies, but not full testing, have been completed for Hambok.

(4)	Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade and contained metal content.

(5)	Tonnage and grade measurements are in metrics units. Contained gold and silver ounces are reported as troy ounces, contained copper and zinc pounds as imperial pounds.

Mineral Reserves

The Proven and Probable Mineral Reserves at the operation have been classified in accordance with the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves. Mineral Reserves are defined within a mine plan, with open pit phase designs guided by Lerchs-Grossmann optimized pit shells, generated using long-term metal prices for copper, zinc, gold, and silver of $2.74/pound, $0.95/pound, $1,100/ounce, and $18.50/ounce respectively. These prices are based on Consensus Market Forecasting that can be applied on long term projects such as Bisha. As of the end of December 2015, the three-year trailing prices for copper, zinc, gold and silver prices were $2.98/lb, $0.91/lb, $1,281/oz, and $19.60/oz, respectively. The current spot market prices for copper , zinc , and silver as of March 14, 2016 are lower than what is used for the long-term reserve calculation. The current spot market price for gold as of March 14, 2016 is higher than what is used for the long-term reserve calculation.

Despite a number of factors including mine depletion during 2015 and a reduction in metal prices, the Company managed to minimize the impact of market conditions on any mineral reserve changes. This was possible primarily because of a) an improvement in the Bisha main resource model; b) a reduction in mining costs; and c) a reduction of treatment charges and shipping costs. The total reserve, inclusive of stockpiles, decreased by 3.1 million tonnes from the year previous which included 248 million pounds of copper. Of this reduction, approximately 1.9 million tonnes and 165 million pounds of copper was due to mill production (mine depletion). The remaining reduction of 1.2 million tonnes and 83 million pounds of copper came from minor changes in the resource model and an increase in cut-off grade for primary ore. Overall, due to higher processing costs forecast for primary ore than the year previous, the Bisha primary reserve decreased by 0.1 million tonnes including a decrease of 1 million pounds of copper and 70 million pounds of zinc. The Harena primary reserve decreased by 0.4 million tonnes including 4 million pounds of copper and 39 million pounds of zinc.

The NSR Cut-Offs (per tonne) are: oxide zone $41.58 for Bisha; supergene zone $41.18 for Bisha; and primary zone $42.92 for Bisha, and $45.48 for Harena.

Pit slope design criteria reflect no change from the previous reserves estimate with overall pit slopes varied from 31.0° to 44° for Bisha, and from 29° to 35.5° for Harena. Revenue will continue to be generated from the sale of copper concentrates (which contain payable co-products of gold and silver) during the supergene ore phase. Both copper and zinc concentrates will be produced during the primary ore phase of the operation that expected to start in late Q2 2016. Small quantities of oxides remaining in the stockpiles will be processed at the end of the mine life through the currently inactive carbon-in-leach circuit, producing doré with payable gold and silver. Some of the high grade gold stockpiles are saleable as Direct Shipping Ore (“DSO”) to be monetised mainly in 2016 and some in 2017.

ANNUAL INFORMATION FORM – December 31, 2015

To capture the multi-rock ore types, variable recoveries by rock type, and multi-element complexity NSR values were calculated for block valuation. The NSR grade determination considers the recoveries, concentrate grades, and penalties (where applicable) for each rock type, and applies the metal prices as noted above and various cost parameters, resulting in a net value per tonne of ore, inclusive of all costs outside the mine gate. Only Measured and Indicated Mineral Resources were considered for processing. Inferred Mineral Resources were treated as waste.

The waste and ore-based costs applied for pit optimization and mine planning were based on 2016 budget costs developed by BMSC. The mining cost (inclusive of loading, hauling, and support including maintenance) was $2.62 per tonne, plus an appropriate incremental haulage cost per bench. The total ore-based costs for Bisha (ore control, geology, lab services, process, G&A and stockpile re-handle) totaled $41.58 per tonne for supergene and $42.92 for primary ores. For Harena, the ore-based costs include an additional $2.56 per tonne for overland ore haulage.

Because the mineralization-waste delineation was performed using an NSR block value, net of downstream costs, the total ore-based cost represents the marginal break-even cut-off grade for pit optimization and mine planning purposes.

The Mineral Resource estimates for Bisha and Harena are undiluted. A 1.0 metre dilution skin was added at the time of ore and waste delineation for mine planning purposes (i.e., as a part of the Mineral Reserves process). Dilution is calculated to be 8% at Bisha main pit. No mining loss adjustments were made.

Factors that may affect the mineral reserve estimates include dilution; metal prices; smelter, refining, and shipping terms; metallurgical recoveries and geotechnical characteristics of the rock mass; operating cost estimates; and effectiveness of surface and groundwater management.

The QPs who prepared this information are of the opinion that these potential modifying factors have been adequately accounted for using the assumptions in this report, and therefore the mineral resources within the mine plan may be converted to mineral reserves. Factors that may affect the assumptions in this report are as follows:

Commodity price assumptions.
The actual Zinc and Copper recovery in primary ore after the zinc plant starts in the middle of 2016.
Mill throughput of the identified ore types may prove to be higher or lower than modelled. If certain rock types or delivered blends of rock types have lower throughputs than currently modelled, this would increase the processing cost which would in turn increase the mill cut-off grade. If all other variables are held constant, this would tend to reduce the tonnage of the Mineral Reserve and the amount of contained metal. If throughput reductions are significant, this could reduce the size of the economic pit limits, further reducing the Mineral Reserve. Furthermore, a reduction in throughput would delay cash flow, resulting in a negative impact on economics. For now, none of this is foreseen to occur.
Effective surface and groundwater management are important to the safety and productivity of the mining operation. If the currently planned water management methods prove to be ineffective, additional dewatering wells and/or sumps and pump systems may be required which would add to the capital and operating costs, resulting in a negative impact on economics and a potential reduction in the Mineral Reserves.

The summary of the Mineral Reserves is shown in the following tables. The Company has done no re- estimates.

Notes to be read in conjunction with the Reserve tables above:

(1)

NSR Cut-Off ($US/t): Oxide zone $41.58/t, Supergene zone $41.18/t and Primary zone $42.92/t for Bisha. The only mineable resource in Harena is Primary zone and the NSR Cut-Off used is $45.48/t. Mineral Reserves are defined within a mine plan, with phase designs guided by LG Pit Shells, generated using metal prices for copper, zinc, gold and silver of $2.74/lb, $0.95/lb, $1100/oz, $18.50/oz respectively. The mining cost was $2.62/t, plus $0.015/t/5 m bench for ore and waste below reference elevations of 560 masl and 600 masl for Bisha and Harena respectively. The total ore-based cost (process, G&A, stockpile and rehandle) are 41.58/t for oxide, $1.18/t for supergene and $42.92/t primary ores. Harena ore-based costs include an additional $2.56/t overland ore haulage cost for 10km distance between Harena pit and the crusher. Overall pit slopes varied from 31 degrees to 44 degrees for Bisha and from 29 degrees to 35.5 degrees for Harena.

Economic values for the multi-metal, multi zones were modelled using Net Smelter Return values. Each block NSR value was calculated using diluted grades, metal prices, recoveries and appropriate smelter terms and downstream costs. Metallurgical recoveries, supported by metallurgical test work, were applied as follows:

30 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

Bisha oxide zone: recoveries of 85% and 30% were applied for gold and silver respectively.

Bisha Supergene zone: recoveries of 83.3%, 55.5% and 70% were applied for copper, gold and silver respectively. Zinc has not been assigned a recovery as most of the supergene zone will be processed prior to start-up of the zinc flotation plant. An arsenic recovery of 60% was applied for smelter penalty inclusion in the NSR calculation and cash flow analysis.

Bisha Transition zone has applied the same metallurgical parameters as Bisha supergene phase. In this zone if the copper to zinc ratio is less than 5 then it is not included in the reserve.

Bisha Primary zone: recoveries to copper concentrate of 85%, 36% and 29% were applied for copper, gold and silver respectively. A zinc recovery to zinc concentrate of 83.5% was applied.

Harena primary zone: recoveries to copper concentrate of 85%, 36% and 29% were applied for copper, gold and silver respectively. A zinc recovery to zinc concentrate of 72% was applied.

Mineral Reserves are reported within Bisha and Harena ultimate pit designs, using NSR block grade, where the marginal cut-off is the total ore based cost stated above. Tonnages are rounded to the nearest 1,000 tonnes. Grades of copper, zinc and gold are rounded to two decimal places. Grades of silver are rounded to one decimal place.

(4)	Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade and contained metal content.

(5)	Tonnage and grade measurements are in metrics units. Contained gold and silver ounces are reported as troy ounces, contained copper and zinc pounds as imperial pounds.

(6)	The life of mine strip ratios (by weight) for Bisha and Harena are 6.50:1 and 5.74:1 respectively.

(7)	The Bisha oxide Probable Mineral Reserves, which include DSO Reserves, are 300 kt at 13.17 g/t Au and 415.17g/t Ag in stockpile as of 31 Dec 2015.

(8)	The Bisha supergene Probable Mineral Reserves are inclusive of 221 kt at 1.83% Cu in stockpile as of 31 Dec 2015.

(9)	The Bisha primary Probable Mineral Reserves are inclusive of 983 kt at 3.36% Zn and 3% Cu in stockpile as of 31 Dec 2015.

(10)	8% dilution was estimated in Primary zone in Bisha after applying 1.0 m "skin" of dilution at ore/waste contacts.

(11)	No mining losses adjustments are made; a 0.5% shipping loss for concentrates have been accounted for.

(12)	The end of December 2015 topography was used for this calculation.

The ultimate Bisha Main pit is planned to be approximately 1.5 kilometres long and 1.0 kilometre wide. The slope heights will range from 160 metres to 290 metres.

Open pit slope design recommendations have been provided for each design sector in each geotechnical domain. Design sectors are defined by the average azimuth of the anticipated wall orientations, based on geological structural controls on slope stability. Geotechnical domains result from the combination of structural domains and geotechnical units, resulting in nine distinct geotechnical domains with the recommended inter-ramp angles varying from 31° to 46°, depending on the design sector and geotechnical domain. All of the slope designs assume that controlled blasting will be undertaken for the final walls of the pit.

Depressurization of the open pit slopes is required to achieve the open pit slope designs, as the pre-development water table is approximately 15 metres below ground surface. Therefore a combination of vertical wells and in-pit sumps (as is the present practice) in use with horizontal drains continue to be installed to dewater the open pit and depressurize the slopes.

The Bisha and Harena deposits are being mined by conventional truck and shovel open pit mining methods. The original Bisha pit consists of nine individual pit phases (although in mid-2015 there was a suspension pending further investigation to Phase 9), where the first three phases targeted oxide ore production, the second three targeted supergene ore production, and the final three phases planned to target primary ore production. The oxide pit phases have now been exhausted, as have Phases 4 and 5 which provided supergene ore. The remainder of the Phase 6 supergene ore will be mined during the first half of 2016. Stripping for the primary mineralization started with Phase 8 in late 2013 and Phase 9 in 2014 and current re-optimisation has suspended Phase 9 stripping from mid-2015 with ongoing Scoping Study Optimisation investigations.

The Harena pit features two pit phases, one targeting oxide production (which was mainly completed in mid-2013 with some remnant material remaining), and the final phase targeting primary production to be active in 2021 for waste stripping with ore extraction scheduled commencing 2023. The Harena pit is currently inactive for mining but additional exploration drilling was completed during 2014 and 2015 and additional work is planned to further investigating a growing at depth deposit to be investigated for underground mining potential.

Although the initial oxide production phase of the operation is complete, approximately 280,000 tonnes of oxide ore have since been mined and placed in stockpiles. The higher grade portion of these stockpiles (90,000 tonnes) are planned to be directly sold during 2016 and the remaining 190,000 tonnes will be processed at the end of the mine life.

The open pit designs for Bisha Main include double lane ramp design widths of 24 metres, based on three and one half times the width of the Cat 775 truck, ramp gradient of 10%, and smoothing of walls in areas where convex “noses” could cause geotechnical issues.

The mine plan for the current December 31, 2015 mineral reserves was developed using an average throughput of 2.4 million tonnes per annum for all materials. Descent rates in the pit were limited to 50 vertical metres per year. Drilling and blasting will be performed on 5 metre benches in ore and waste ranging between 5 and 10 metres. The mine is scheduled to work 360 days a year, with five days allowed for delays due to weather disruptions. The plant is scheduled to operate 365 days a year.

The mine delivers ore to the ROM pad, where it is sorted into several different short-term stockpiles. This ore is then reclaimed by a front-end loader to the dump pocket, following a blending plan that is provided daily and modified as required based on process plant performance. Longer-term stockpiling of non-oxide material has been minimized to limit oxidization.

Bisha has three different types of mineralization – oxide, supergene, and primary – each requiring a specific process flow sheet. The plan in the 2006 Bisha Feasibility Study to mine and process each zone in succession starting with the top oxide zone (now ceased), is still being followed. The oxide plant facilities included a primary jaw crusher, a single Semi-Autogenous Grinding followed by single ball grinding mills, cyanide leach/carbon-in-leach circuit, cyanide destruction circuit, refinery to produce doré bullion, tailings thickener, tailings discharge system, and the necessary reagent, water, and air systems. Additional process equipment as part of the copper flotation plant to treat the supergene mineralization was commissioned by mid-2013 and installed downstream of the crushing and grinding “front end” part of the carbon-in-leach plant which treated the oxide ore. This equipment consists of flotation cells for copper roughing and cleaning duties, regrind mills for size reduction of rougher concentrate, copper concentrate thickener and pressure filters, a copper concentrate load-out building, copper flotation reagent systems, flotation air blowers, and pressure filter air compressors. A decision was made in 2014 and construction completed in Q1 2016 to replace the 4 x Metso vertical regrind mills in the copper flotation plant with an IsaMill^TM regrind mill, to be commissioned in Q2 2016. A near identical duplicate of this copper flotation circuit is being constructed downstream for the upcoming zinc flotation circuit, to be commissioned in late Q2 2016.

Due to the sub-horizontal and undulating contact between the supergene and primary mineralized materials, there will be a multi-year period where both minor amounts of supergene and dominant primary materials are mined and processed during 2017 and through 2019. During this overlap period, both supergene and primary ores will be treated in campaigns of appropriate durations. Some stockpiling of supergene and primary mineralization types has and will continue to occur. The effect of any possible sulphide mineral oxidation on flotation performance is minimized by management practices currently used in the base metal sulphide sector, such as reduced wetting of broken ore.

The current life of mine plan starts from the December 2015 end-of-month surveyed surface. Over the remaining LOM, the waste rock which will be produced from the Bisha Main and Harena pits will continue to be placed in two waste rock facilities to the east and southeast of the Bisha Main open pit, as well as in a backfill dump located in the north end of the ultimate Bisha Main pit. The east waste rock facility nominally covers 80 hectares, and the southeast waste rock facility nominally covers 90 hectares. An operational scheduling plan has been prepared for placement of the rock within the dumps that allows potential acid rock drainage issues to be appropriately managed during operations and closure.

There remain four distinct types of stockpiled material – 192,000 tonnes of supergene ore, 410,000 tonnes of pyrite sand, 280,000 tonnes of oxide ore, and 980,000 tonnes of primary ore.

The pyrite sand material consists of 30,000 tonnes of higher grade ore of which approximately 50% will be monetized during 2016. Further study is required to determine the economics of the remaining 380,000 tonnes of the lower grade pyrite sand material.

Given the current base metal commodity price, the Company undertook a study to determine different alternatives to monetize the stockpiled 280,000 tonnes of oxide ore earlier than the 2014 LOM Plan which had been to process at the end of the mine life. After drilling, crushing, and metallurgical testing of the higher grade portions of the oxide ore stockpiles, the Company has determined it is more economic to directly sell some of this material. Accordingly, the Company intends to sell approximately 90,000 tonnes of high grade oxide ore during 2016. The remaining 190,000 tonnes will be processed at the end of the mine life.

33 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

The 980,000 tonnes of primary ore is intended to be processed in a blended manner through the new zinc plant. The Company has revised its estimate of the amount of this stockpile that will be processed during 2016 and now expects just over 50 percent of the material to be processed in 2016 dependent on the exhibited flotation characteristics.

The composition of stockpiled materials as at December 31, 2015 is as follows:

Table 3.2 Stockpiled Materials

	Total	Current	Non-current
Supergene ore	192,000	192,000	-
Primary ore	980,000	526,000	454,000
Oxide ore	280,000	90,000	190,000
Pyrite sand ore	410,000	15,000	395,000

Life of Mine Optimization Study

In Q2 2015, Nevsun commissioned SRK Consulting (Canada) Inc. to conduct an internal conceptual study of the potential for underground mining at Bisha and Harena as well as to conduct a LOM optimization study considering all Bisha regional resources. As this optimization study used inferred mineral resources, no mineral reserves have been estimated. The status of those assessments for Harena and Bisha are outlined below. The deposits at Hambok and Northwest remain of interest for potential eventual economic extraction based upon a number of variables including size, projected costs and metal prices. As the assessments of Hambok and Northwest were less encouraging as compared with Harena and Bisha, the Company has elected to allocate investment capital to Harena and Bisha for 2016 with limited investment for Hambok and Northwest for 2016.

Bisha Underground

Ongoing investigations during H2 2015 continued to assess the reasonable prospects of eventual economic extraction of the currently defined Indicated and Inferred mineral resources at Bisha Main pit by means of underground mining methods. Conceptual mining constraints were used to assess the potential optimum interfaces between open pit mining and underground mining for the purposes of updating future mineral reserves and the associated production profile which may be revised as a result. The interim results of the ongoing internal study indicate that underground mining at Bisha is plausible and that some of the material currently in the open pit mine plan may be more economic if extracted by underground bulk mining methods as compared with high strip ratio open pit cutbacks. However, based on work to date, there are no significant changes to the year-on-year mineral reserves nor the existing mine life. An exploration drive at Bisha main pit will be required to further assess this opportunity with increased drilling to upgrade mineral resource classifications and further investigate geotechnical, hydrology and metallurgical rock characteristics. The Company plans to continue metallurgical test work and exploration resource extension drilling during 2016. A decision to drive an exploration ramp most likely in H2 2017 will be made following this further planned exploration drilling and metallurgical and geotechnical test work.

Phase 9 from the 2014 LOM Plan provided access to ore in years 2021 through 2026. The basic economic concept of the internal conceptual investigations was to evaluate the trade-off of potentially saving approximately $270 million (approximately $3 per tonne) in open pit mining costs against the cost of underground development and underground mining, as well as the potential changes in reserve material and the time value of the change in mine plan. Further work is warranted before any definitive conclusions are reached and mine plans are officially changed. Management believes that the temporary suspension of the cutback (Phase 9) of the Bisha open pit and continued deferral of portions of Phase 8 is warranted but not irreversible, pending the results of a pre-feasibility study to be completed over the next two years.

ANNUAL INFORMATION FORM – December 31, 2015

Harena Underground

For Harena, the underground mining conceptual investigations used an interim mineral resource calculated mid-2015 which has since been superseded by the current larger resource as announced on February 17, 2016. The latest findings of this ongoing work imply a potentially mineable deposit with marginal economics that is sensitive to metal prices and metallurgical recoveries. Therefore, additional metallurgical drilling at Harena is planned during 2016 before making a decision to invest in an exploration decline which would be required to take the deposit through feasibility.

Scoping Study

An updated Technical Report from the 2013 Technical Report (filed March 24, 2014) is expected in Q1 2017 after commissioning and operation of the zinc flotation circuit. It will include the further planned 2016 scoping level investigations at Bisha and Harena noted above which will be shared in Other Relevant Data and Information of the future report.

Capital and Operating Costs

Capital and operating costs for the Bisha Property are shown in the table below.

Table 3.3 Capital and Operating Costs (‘000s)

	2015 Actuals $	2016 Outlook $
Operating Expenses	200,890	200,000-220,000
Capital Expenditures:
Zinc Plant Expansion	48,202	15,000
Capitalized Exploration	11,378	11,000
Sustaining Capital (Including Bisha Optimization Study)	25,859	9,000
Total Capital Expenditures	85,439	35,000

Operating expenses include mine operating costs as well as commercialization costs comprised primarily of trucking, port and shipping costs. Operating expenses for the 2016 Outlook include expenses that are expected to be capitalized during the pre-commercial production phase of the new zinc plant in accordance with the Company’s accounting policy for mineral properties, plant and equipment. The amount that is ultimately capitalized, net of proceeds from the sale of metals extracted during this pre-commercial production phase, is dependent on the length of time required for the commissioning of the new assets.

Metallurgical Test Work and Process Plant Design

The Bisha Property mineral resource contains three ore types: a gold and silver bearing oxide cap, underlain by a more complex secondary copper mineralized supergene ore which is in turn underlain by primary copper-zinc ore where chalcopyrite (copper) and sphalerite (zinc) are the main economic minerals.

The metallurgical performances of the three ore types corresponding with metallurgical test data completed in 2013 and 2014 coupled with actual observed behaviour in 2013 through 2015 are summarized in the table below.

ANNUAL INFORMATION FORM – December 31, 2015

The oxide, supergene and primary ores require different processing techniques and equipment. Oxide ore processing ceased in Q2 2013 whereupon supergene ore commenced. The current plan is to mine the remaining two zones (supergene zone at Bisha Main which is nearly complete and the primary zones at Bisha Main and Harena) in succession with some minor overlap of supergene and primary ore up to 2019. This is pending further reviews to economically optimize the mine production schedule. When the supergene ore availability diminishes, which is anticipated by late Q2 2016, the current flotation plant treating supergene ore will have been suitably modified, with the addition of a zinc flotation circuit, to accept its first primary copper-zinc ore.

The additional equipment to be installed (over 95% complete as of date of this AIF) will include zinc roughing and cleaner flotation sections, zinc rougher concentrate regrinding, zinc concentrate thickener and pressure filters, a zinc concentrate load-out facility, zinc flotation reagents system, a tailings return water treatment facility to recycle approximately 50% of water sent to tails and additional flotation air blowers. This will allow a manageable transition from processing the supergene ore to primary copper-zinc ore. There will be some transition period where campaign treatment of both ore types may be required during 2017 until 2019. While anticipated production will not be affected, there will be some fluctuation in concentrate grades; however, no interruption to production is anticipated, as campaign processing of different ore types is an established practice in the treatment of base metals sulphide ores.

In 2013, 89,800 dry metric tonnes (“DMT”) of concentrate was produced with the copper grade of 24.3% containing 21,800 tonnes of copper. In 2014, 337,500 DMT of concentrate was produced with the copper grade of 26.3% containing 88,900 tonnes of copper. Average copper recovery in 2014 was 85%. In 2015, 260,900 DMT of concentrate was produced with the copper grade of 23.6% containing 61,600 tonnes of copper. Average copper recovery in 2015 was 83%. An average of approximately108,000 tonnes of copper concentrate per year and 175,000 tonnes of zinc concentrate per year will be produced commencing in 2016 to 2025. The average copper grade in the primary ore is 1.1% compared to 2.2% in the remaining supergene ore in 2016. The average zinc grade in the primary ore is 5.6%.

Concentrate is loaded from the dewatered mine site stockpile, sealed in special shipping containers and transported to the existing container port of Massawa on the Red Sea by truck. The concentrate is exported using a proven system with industry leading environmental controls. The sealed containers are stockpiled in Massawa at the container port facilities while waiting for ship arrival. The mobile crane system then lifts the containers with a specialised 360-degree rotating spreader (termed a Rotainer system) and discharges the concentrate from the containers into bulk vessels. The empty containers are returned to the Bisha Mine for re-loading. The bulk vessels deliver the concentrate to copper smelters worldwide.

Mine Waste and Water Management

Waste rock from the Bisha open pit is being placed in two separate waste rock dumps, non-acid generating (“NAG”) and potentially acid generating (“PAG”). The decision on where to place future waste rock excavated during pit stripping is based upon waste rock characterization laboratory work. Waste rock characterization at Harena has indicated there is no potential acid generating for the oxide zone and consequently no requirement for drainage and sump systems. Waste rock dump locations are determined taking into account the level of environmental impact, optimizing mining operations, and permit expansion of mining areas based on further exploration programs. The Bisha PAG waste rock dump has been designed with a compacted low permeable soil base layer, drainage and seepage collection system, and sumps to facilitate re-use of any seepage in the process plant should it occur. Design criteria at both pits allows for gravity drainage to the open pits on closure. PAG waste will be encapsulated to control potential acid leachate generation.

Tailings generated from the processes are pumped to the TMF situated to the north of the process plant. Site selection of the TMF was based on storage characteristics of the basin and natural topography, extent of environmental impact and embankment construction requirements. The TMF is lined with an impermeable High Density Polyethylene liner to reduce any potential impact to groundwater aquifer and/or downstream users. Tailings deposited since commissioning is approximately 8.3 million tonnes (4.5 million tonnes from the oxide zone and 3.8 million tonnes from the supergene zone). A return water methodology of operation ensures re-use of this valuable resource as far as practicable but further work is being undertaken in 2016 to further improve TMF return water rates. As the gold phase was complete in the middle of 2013 (and hence no longer using cyanide), and a subsequent lift completed to the tails

36 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

facility in mid-2014, cyanide in the TMF has dissipated through natural solar destruction and is no longer a concern. The first 3-metre lift of the existing TMF was completed in April 2014 and there are currently 4.1 metres of freeboard remaining.

Natural acid generation from the sulphides of the supergene zone is a new issue in the pit and steps are in place to mitigate this influence on the environment by sending all pit water to the lined TMF. BMSC is currently in the process of upgrading its TMF return water neutralisation circuit that will have sufficient capacity to manage both TMF return water and pit water.

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. Three separate diversions in the Ferektatet River ensure that storm water is directed away from operations to both the east (Shatera River) and the west (Mogoraib River). Groundwater is the main water source for the process plant, the volume of which is reduced by a zero discharge policy, judicious re-use of poor quality pit sump water and maximum use of dewatering well waters.

Socioeconomic and Environmental Assessment and Approval

The environmental assessment phase of Bisha Mine commenced with baseline studies in 2004. The Eritrean Ministry of Energy and Mines approved the Terms of Reference for the SEIA project 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 2006 Bisha Feasibility Study. The project SEMPs 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. 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 LOM. There have been no material adverse social or environmental impacts identified.

The Company is aligning its environmental systems with the IFC Performance Standards and developing its management plans accordingly. The plans have been subject to review by the host country, 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. 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.

SEMPs are in place and serve to assist the Company in achieving compliance of the operation to both Eritrean legislation and where this is not available, to international best practice or standards. An in-house review and update of the SEMPs was conducted during 2012 based on comments received by the Impact Review Committee. An independent review and update of the SEMP was completed in Q2 2013 and has addressed the updated roles and responsibilities in the SEMP. Internally, policies and statements of intent have been developed with respect to environmental policy, water conservation, energy conservation, cyanide management and materials management. These policies will be augmented with training, awareness and toolbox talks, with the goal of implementing these policies throughout the workforce. An extensive environmental monitoring program which includes air quality (ambient and operational dust and emissions), noise (ambient and operational), water qualities and quantities, and natural resources, to measure the effectiveness of the proposed mitigation actions in the environmental management plans.

The Company continues to consult and work closely with government ministries through the submission of annual and quarterly reports and quarterly inspections by the Impact Review Committee and will continue to do so throughout the LOM. There have been no adverse social or environmental incidents since the commencement of commercial operations.

Other Expansion Plans

BMSC has advanced its zinc expansion project through 2015, with a target start-up scheduled in late Q2 2016. An increased owner’s team was assembled versus the copper expansion project. Key portions of

37 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

the engineering and procurement were sourced to Outotec, Xstrata technology (Glencore) and SENET. The zinc expansion project remains on schedule for ore commissioning in late Q2 2016 at a projected total cost of approximately $80 million. The Company has commenced discussions with interested zinc smelters and traders on the sale of zinc concentrates from the Bisha Mine. Early feedback indicates that Bisha’s zinc concentrate will be highly desired for its concentrate quality. The Company remains uncommitted to any future zinc off-takes as the Company believes recent mine shutdowns and production cutbacks in the zinc market will lead to a tighter market for zinc concentrates in the second half of 2016 and into 2017.

Exploration and Development

A further $11 million in exploration investment is planned for 2016. Key 2016 exploration objectives which will be prioritized on a success basis for additional work include:

Expanding the resource at Harena through drilling and down-hole geophysics;
Drilling high priority targets at depth and on strike from Bisha Main; and
Continued testing of high priority greenfield targets on the Mogoraib River exploration license.

BMSC expects to drill in excess of 34,000 metres during 2016.

The major development work will be the completion of the primary metallurgical test work to assist with confirmation of design of the primary flotation circuit and continued progress with the engineering design, procurement and construction of the plant due for completion in Q2 2016.

The Company has considerable additional value held in stockpiles that has yet to be monetized. The Company has already encountered primary zone material which has been stockpiled for the primary phase. There are two other distinct types of stockpiled material – pyrite sand material and oxide ore.

As at December 31, 2015, there are approximately 410,000 tonnes of pyrite sand material containing over 60,000 ounces of gold with significant silver content and 130,000 tonnes of oxide ore at over 5 g/t gold containing over 20,000 ounces of gold. For the pyrite sand stockpiles, 30,000 tonnes are of higher grade ore approximately 50% of which the Company plans to monetize in 2016. Further study is required to determine the economics of the remaining 380,000 tonnes of the lower grade pyrite sand material. For the oxide ore stockpiles, the Company intends to directly sell approximately 90,000 tonnes of the higher grade ore in 2016. The remaining 190,000 tonnes will be processed at the end of the mine life.

Schedule “B” – Risk Factors

Approach to Risk Management

The Company’s approach to identifying and managing risk has been a critical component of how management runs and the Board oversees management of the business. The Company’s enterprise risk management process is currently coordinated by the Chief Financial Officer, managed by the senior management team with direct oversight by the Chief Executive Officer and the Board of Directors. The Company conducts a top down review of key strategic, operational and financial risks at least quarterly. The Company maintains a risk register, which is updated on a monthly basis by the appropriate business owner of the risk. The risk register contains a list of actions to ensure risks are mitigated to the agreed upon level of risk tolerance. The results of the Enterprise Risk Management process are reviewed quarterly by the Audit Committee and semi-annually by the Board of Directors.

The business and operations of the Company are highly speculative due to the high-risk nature of its business in the mining industry, including but not limited to the acquisition, financing, exploration, development, operation and production of metals at its mining properties. The Company’s business is subject to strategic, financial and operating risks. The risks below, some of which are summarized elsewhere in this Report, are not the only ones faced by the Company. Additional risks not currently known to the Company, or that the Company currently deems immaterial, may also arise in the future and impair the Company’s operations. If any of the following risks actually occur, the Company’s business, financial condition and operating results could be adversely affected.

Strategic Risk Factors

Foreign operation and political risks. The Company conducts operations in Eritrea through its foreign subsidiaries with financial assets in Barbados and 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 stable environment for its operations, there is no guarantee against any future political, or economic instability in these countries or neighboring countries that might adversely affect the Company.

Political unrest in Egypt, Libya, Syria, Yemen, Saudi Arabia, Somalia, South Sudan, Sudan 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. New government regulations in Canada, the United States or other countries in which the Company operates could adversely affect the Company’s future business and operations. In addition, intervention by the international community through organizations such as the United Nations could affect the political risk of operating in Eritrea. In December 2009 the United Nations Security Council (UNSC) imposed sanctions on Eritrea related to an arms embargo, which in itself has had no direct impact to the Bisha Mine, except to cause some uncertainty as to how UN member states may continue to deal with the country. In December 2011 the UNSC provided additional sanctions guidance to member states. Effects of the sanctions could impact the Company’s ability to operate efficiently. There are also unresolved tensions between Ethiopia and Eritrea and the possibility of future armed conflicts between Ethiopia and Eritrea by rebel groups or otherwise which could affect or interfere with continued operations at Bisha.

Other risks the Company may face in operating in foreign jurisdictions include unforeseen government actions, acts of god, terrorism, hostage taking, military repression, extreme fluctuations in currency exchange rates, high rates of inflation, 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, and changing political conditions, currency controls, export 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 or other events.

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.

52 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

Governmental regulatory risks. The Company’s mineral exploration, development and production activities are subject to various laws governing prospecting, development, production, taxes, labour standards and occupational health, mine safety, toxic substances, environmental protection and preservation, and other matters. No assurance can be provided that the Company will be successful in its efforts to comply with all existing rules and regulations, that new rules and regulations will not be enacted, or that existing rules and regulations will not be modified in a manner that could limit or curtail production or development of the Company’s properties. All such rules and regulations governing the operations and activities of the Company could have a material adverse effect on the Company’s business, 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. The loss of one or more of these persons or the Company’s inability to attract and retain executives and personnel with the qualifications necessary to successfully operate the business may adversely affect the Company’s business and future operations. The Company competes with numerous other companies for the recruitment and retention of qualified executives and employees and thus there is a risk that from time to time one or more key executives or personnel move to a competitor.

Expatriate and nationals’ skills risk. The Company’s Eritrean operations are the first modern commercial mining operation in that jurisdiction. As a result, the Company is reliant on attracting and retaining expatriate and nationals with mining experience to staff key operations and administration management positions. The Company’s inability to attract and retain personnel with the skills and experience to manage the operation and train and develop staff, due to the intense international competition for such individuals, may adversely affect its business and future operations.

Competition risks. The mining industry is intensely competitive in all of its phases and the Company competes with many companies possessing greater financial and technical resources than itself. There is intense competition in the mining industry for mineral rich properties that can be developed and produced economically, the technical expertise to find, develop, and operate such properties, the labour to operate the properties, and the capital for the purpose of funding such properties. Many competitors not only explore for minerals, but conduct refining and marketing operations on a global basis. Such current and future competition may frustrate the Company’s ability to acquire desired properties. The Company is also subject to risks associated with a hostile takeover of the common shares of the Company or other unsolicited attempts to acquire control of the Company.

Acquisitions and integration risks. The Company continues to examine opportunities to acquire additional mining assets and businesses. Any acquisition that the Company may choose to complete may be of a significant size, may change the scale of the Company’s business and operations, and may expose the Company to new geographic, political, operating, financial and geological risks. The Company’s success in its acquisition activities will depend on its ability to identify suitable acquisition candidates, negotiate acceptable terms for any such acquisition, and integrate the acquired operations successfully with those of the Company.

Any acquisition transactions would be accompanied by some risks. For example, a material ore body may prove to be below expectations; the Company may have difficulty integrating and assimilating the operations and personnel of any acquired companies, integrating internal controls over financial reporting of such acquired companies, identifying and mitigating any potential domestic or foreign liabilities, including potential liabilities due to foreign anti-corruption laws, realizing anticipated synergies and maximizing the financial and strategic position of the combined enterprise, and maintaining uniform standards, policies and practices across the organization; the integration of the acquired business or assets may disrupt the Company’s ongoing business and its relationships with employees, customers, suppliers and contractors; and the acquired business or assets may have unknown potential liabilities that may be significant.

In the event that the Company chooses to raise debt capital to finance any such acquisition, the Company’s leverage will be increased. If the Company chooses to use equity as consideration for such acquisition, existing shareholders may suffer dilution as a result. Alternatively, the Company may choose to finance any such acquisition with its existing capital resources. There can be no assurance that the Company would be successful in overcoming these risks or any other problems encountered in connection with such acquisitions.

ANNUAL INFORMATION FORM – December 31, 2015

Litigation risk. The Company is subject to litigation risks. The mining industry is subject to legal risks and claims. Such legal claims can relate to various matters including, without limitations, mining laws, environmental laws, labour laws and anti-corruption and anti-bribery laws in the juridsictions in which the Company operates. Defense and settlement costs associated with legal claims can be substantial, even with respect to claims that are frivolous or have no merit. Due to the inherent uncertainty of the litigation process, the resolution of any particular legal proceeding to which the Company is or may become subject could have a material adverse impact on its financial performance, cash flow and results of operations, including the Araya Lawsuit described under the heading “Legal Proceedings”.

Share price risk. The market price of a publicly traded stock is affected by many variables not directly related to the success of the Company, including the market for all resource sector shares, the breadth of the public market for the stock, and the attractiveness of alternative investments. 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, 2014 and December 31, 2015 the Company’s shares traded in a range between CAD $3.32 and CAD $5.35.

Dividend policy risks. The Company has established a dividend policy that has considered the long-term sustainability of cash flows and will be reviewed on a periodic basis and assessed in relation to the historical and anticipated growth of the Company’s operating cash flows. The Company began paying dividends in July 2011. The Company has increased its annual dividend every year since that time. During 2015, the Company paid quarterly dividends of $0.04 per share. Payment of any future dividends will be at the discretion of the Board after taking into account many factors, including the Company’s operating results, financial condition, comparability of the dividend yield to peer mining companies and current and anticipated demands on the Company’s cash levels. There can be no assurance that the Company will continue to pay dividends at the current rate or at all.

Conflicts of interest. Certain of the directors and officers of the Company also serve as directors and/or officers of other companies involved in natural resource exploration and development and consequently there exists the possibility for such directors and officers to be in a position of conflict. Any decision made by any of such directors and officers involving the Company will be made in accordance with their duties and obligations to deal fairly and in good faith with a view to the best interests of the Company and its shareholders. In addition, each of the directors is required to declare and refrain from voting on any matter in which such directors may have a conflict of interest in accordance with the procedures set forth in the Business Corporations Act (British Columbia) and other applicable laws.

Financial Risk Factors

Commodity price risk. Revenue and profitability of the Company’s operations will be dependent upon the market price of mineral and materials commodities. Prices of metals are key performance drivers for the Company and fluctuations in the prices of these commodities can have a significant impact on the Company’s operations and financial performance. The Company does not enter into any commodity hedging and accordingly is fully exposed to price risk. The price of copper, 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 or deflation, currency exchange fluctuations (specifically, the US 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 copper, gold and other metals are affected by various factors, including political events, economic conditions, competition, production costs, and governmental policies. If the market price of copper, zinc, gold or silver falls significantly from its current level, the production and ongoing mine development at Bisha or any other project of the Company may be rendered uneconomic and the production or development at Bisha or any other project may be suspended or delayed. In addition, if the market price of copper, zinc, gold or silver were to decrease significantly and remain at lower levels for a significant period of time, profitability of the Company and cash flow would be negatively affected.

Mineral reserve calculations and life-of-mine plans using significantly lower metal prices could result in material write-downs of the Company’s investment in mining properties and increased amortization, reclamation and closure charges. In addition to adversely affecting the Company’s mineral reserve estimates and its financial condition, declining commodity prices can impact operations by requiring a reassessment of the feasibility of a particular project. Such a reassessment may be the result of a management decision or may be required under financing arrangements related to a particular project. Even if the project is ultimately determined to be economically viable, the need to conduct such a reassessment may cause substantial delays or may interrupt operations until such time as the reassessment can be completed.

ANNUAL INFORMATION FORM – December 31, 2015

The Bisha Mine’s power generation plant and mobile equipment fleet are fueled by diesel petroleum. As fuel costs are a significant component of the Company’s operating costs, changes in the price of diesel could have a significant effect on its operating costs and adversely affect profitability. Energy prices can be affected by numerous factors beyond the Company’s control, including global and regional supply and demand, political and economic conditions and applicable governmental policies.

Funding risks. The exploration, development, operations, acquisitions or other activities may require substantial additional debt and capital financing. Failure to obtain sufficient financing may result in delaying or indefinite postponement of exploration, development, operations, acquisitions or other activities of the Company including a loss of property interest. Historically, the Company has financed its activities through the sale of equity capital and through cash flow from operations. The sale of metals from Bisha currently provides and is expected to continue to provide revenue from operations, which the Company expects will be sufficient to fund its future needs. Factors which may impact cash flows include changes in metal prices, taxes, operating costs, marketability of metals from operations, capital expenditures or other unexpected occurrences such as unanticipated costs, delays, downtimes, 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.

Insurance risks. Although the Company believes it maintains adequate insurance coverage to protect against certain risks at levels it considers reasonable, its insurance will not cover all the potential risks associated with a mining company’s operations. Nevsun may also be unable to maintain insurance to cover these risks at economically feasible premiums. In addition, insurance coverage may not continue to be available in the future or may not be adequate to cover any resulting liability.

Write-downs and impairments risk. Mining and mineral interests are the most significant assets of the Company and represent capitalized expenditures related to the development of mining properties and related plant and equipment.

The Company reviews and evaluates its mining interests for impairment at each reporting period or when events or changes in circumstances indicate that the related carrying amounts may not be recoverable, which evidences greater risk levels due to changes in the global economic conditions that exist currently. An impairment is considered to exist if the total estimated future undiscounted cash flows are less than the carrying amount of the assets. An impairment loss is measured and recorded based on discounted estimated future cash flows. Future cash flows are estimated based on expected future production, commodity prices, operating costs and capital costs. There are numerous uncertainties inherent in estimating mineral reserves and mineral resources. Differences between management’s assumptions and market conditions could have a material effect in the future on the Company’s financial position and results of operation.

The assumptions used in the valuation of long-term stockpiles and work-in-process inventories by the Company include estimates of metals contained in the ore stockpiles, crushed ore piles, processing plant circuits, and an assumption of the metal prices expected to be realized when the copper, zinc, gold and silver are recovered. If these estimates or assumptions prove to be inaccurate, the Company could be required to write-down the recorded value of its long-term stockpiles or work-in-process inventories, which would reduce the Company’s earnings and working capital.

Derivatives risk. In the future the Company may use certain derivatives products to manage the risks associated with changes in metal prices, interest rates, foreign currency exchange rates and fuel prices. The use of derivative instruments involves certain inherent risks including, among other things: (i) credit risk – the risk of default on amounts owed to the Company by financial counterparties; (ii) market liquidity risk – the risk that the Company has entered into a derivative position that cannot be closed out quickly, by either liquidating such derivative instrument or by establishing an offsetting position; and (iii) unrealized mark-to-market risk – the risk that, in respect of certain derivative products, an adverse change in market prices for commodities, currencies or interest rates will result in the Company incurring an unrealized mark-to-market loss in respect of such derivative products.

55 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

Counterparty risks. The Company is exposed to various counterparty risks including, but not limited to: (i) financial institutions that hold the Company’s cash and cash equivalents; (ii) amounts owing to the Company by copper concentrate customers; and (iii) amounts owing to the Company by ENAMCO in connection with the purchase price for their 30% interest in BMSC. As a result, the Company may become exposed to credit-related losses in the event of non-performance by such counterparties.

Currency risks. At present all of the Company’s operations other than head office corporate functions 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 Canadian dollar (CAD), South African rand (ZAR), the Eritrea Nakfa (ERN), and the Euro. While only a small portion of the Bisha Mine’s operating expenses are denominated in ERN, a re-valuation or de-pegging of this currency to the USD could expose the Company to additional currency risk. Fluctuations in currency exchange rates could significantly affect the Company’s business, financial condition, results of operations and liquidity.

Information technology security risk. Nevsun maintains information technology infrastructure, applications and communications networks to support its business activities. These systems could be subject to security breaches resulting in theft, disclosure or corruption of information, including information relating to acquisitions and divestments, strategic decision-making, investment market communications or commercially sensitive information relating to major contracts. Security breaches could also result in misappropriation of funds or disruptions to business operations.

Operation Risk Factors

Mineral reserve and mineral resource estimate risk. The tabulated data for mineral reserves and mineral resources presented in figures in this document and contained in the Company’s continuous disclosure documents filed on SEDAR (www.sedar.com) and EDGAR (http://www.sec.gov/edgar.shtml) are estimates generated by Qualified Persons, 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 metallurgical recovery will be realized. Actual reserves may not conform to geological, metallurgical or other expectations, and the volume and grade of ore recovered may be below the estimated levels. 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.

There are numerous uncertainties inherent in estimating quantities of mineral resources and reserves, including many factors that are beyond the Company’s control. The estimates prepared by the Company 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 including costs of fuel and other critical operating consumables, 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 or any assumptions in the historical resource estimates that turn out to be incorrect, incomplete or flawed in any respect or the methodologies and models used to prepare the resource and reserve estimates either underestimate or overestimate the resources or reserves due to hidden or unknown conditions, could result in material downward or upward revision of current estimates.

Exploration, 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

56 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

environmental pollution and consequent liability. The Company may at times experience some difficulty in managing the sulphide rich reactive ground^{^[1]} which may affect blasting and continuous ore supply and give rise to unplanned detonations resulting from reactive ground, or a failure of drilling, processing and mining equipment or unanticipated costs and downtimes due to optimizing the copper flotation plant and its operating facilities. These costs, downturns and other risks can have a material adverse effect on the Company’s operating costs and resultsof operations and financial position.

The exploration for and development of mineral deposits involves significant risks, which even a combination of careful evaluation, experience and knowledge may not eliminate entirely. While the discovery of an ore body may result in substantial rewards, few properties that are explored are ultimately developed into producing mines. 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. Whether a mineral deposit will be commercially viable depends on a number of factors, which include, among other things, the interpretation of geological data obtained from drill holes and other sampling techniques, feasibility studies (which include estimates of cash operating costs based upon anticipated tonnage and grades of ore to be mined and processed), the particular attributes of the deposit such as size, grade and metallurgy, expected recovery rates of metals from the ore, proximity to infrastructure and labour, the cost of water and power, anticipated climatic conditions, cyclical metal prices, fluctuations in inflation and currency exchange rates, higher input commodity and labour costs, and government regulations, including regulations relating to prices, taxes, royalties, land tenure, land use, importing and exporting of minerals, and environmental protection.

Major expenses may be required to locate and establish additional mineral reserves. It is impossible to ensure that the exploration or development programs planned by Nevsun will result in additional profitable commercial mining operations. The exact effect of these factors cannot be accurately predicted, but the combination of these factors may result in Nevsun not receiving an adequate return on invested capital. In this regard the Company relies to a significant degree on the analyses performed by its Qualified Persons to estimate resources and reserves, and such estimates may be subject to material risks and uncertainties.

Production risk. As is typically the case with the mining industry, no assurances can be given that future mineral production estimates will be achieved. Estimates of future production for the Company’s mining operations are derived from the Company’s mining plans. These estimates and plans are subject to change, including changes based on actual mining results at various phases of the mining operations. The Company cannot give any assurance that it will achieve its production estimates. The Company may not be able to effectively manage potential deleterious elements contained within the ore to ensure continued salability of concentrates produced at projected costs. The Company may not be able to effectively manage the combination of oxidation of ore stocks coupled with in pit water inflow that may adversely affect flotation and quality of concentrates produced. There is a further risk that the potential reactive nature of the ore and waste with high pyrite (sulphides) content and its reactivity with ammonium nitrate contained in explosives will have a negative impact on ore and waste blasting efficiencies and result in increased costs. An additional risk includes the true understanding of the full extent and mineralogical properties of the transition zone between the supergene and primary ore bodies and the subsequent potential disruptive impact on processing this zone, even if campaigned in discrete periods, on the quality and future salability of the concentrates produced. Any process plant adjustments or modifications to further optimize and improve operating efficiencies could result in significant capital expenditures and have an impact on process plant productivity or result in a temporary shutdown to rectify the issues. Failure to effectively manage these and other matters and to achieve its production estimates could have a material and adverse effect on the Company’s future cash flows, results of operations, production cost, financial condition and prospects. The plans are developed based on, among other things, mining experience, reserve estimates, assumptions regarding ground conditions, hydrologic conditions and physical characteristics of ores (such as hardness and presence or absence of certain metallurgical or mineralogical characteristics) and estimated rates and costs of

________________________________

production, and include assumptions derived by geological block models developed by the Qualified Person(s) in consultation with Company personnel. Actual production may vary from such estimates for a variety of reasons, including risks and hazards of the types discussed above, and as set out below, including but not limited to:

greater mining dilution than expected affecting geological grades and material movement;
accidents;
mobile and fixed plant equipment failures;
natural phenomena such as inclement weather conditions, floods, droughts, rock slides and earthquakes;
unforeseen geotechnical structures and faults leading to pit wall failures and production delays;
adverse chemical nature and potential acidity and amount of in-pit water;
unexpected or higher than anticipated occurrence of deleterious elements in the ore such as arsenic, selenium and tellurium impacting subsequent concentrate quality;
higher than expected oxidation of in-pit ore stocks adversely impacting flotation characteristics and subsequent concentrate quality;
unexpected mineralogical properties of the supergene to primary transition zone and impact on concentrate quality;
encountering unusual or unexpected mineralogy conditions including reactive sulphide rock with ammonia nitrate based explosives adversely affecting blasting procedures and productivity;
changes in power costs and potential power shortages;
shortages of principal supplies (fixed components, parts and consumables) needed for operations;
strikes and other actions by labour;
unanticipated costs, delays or downtime due to maintenance or further required optimisation of the process plant and operation facilities; and
existing and new regulatory restrictions imposed by government agencies.

Such occurrences could, in addition to stopping or delaying mineral production or impacting quality and salability of metal concentrates, result in damage to mineral properties, injury or death to persons, damage to the Company’s property or the property of others, monetary losses and legal liabilities. These factors may also cause a mineral deposit that has been mined profitably in the past to become unprofitable in the future. Estimates of production from properties not yet in production or from operations that are to be expanded are based on similar factors (including, in some instances, feasibility studies prepared by the Company’s personnel and outside consultants) but it is possible that actual operating costs and economic returns will differ significantly from those currently estimated.

Need for additional reserves risk. Given that mines have limited lives based on proven and probable mineral reserves, the Company must continually review, replace and expand the reserves at its mines. The life-of-mine estimates included in the Company’s continuous disclosure documents filed on SEDAR and EDGAR are subject to continual adjustment. The Company’s ability to maintain or increase its annual production of gold, copper and other commodities will be dependent in significant part on its ability to bring new mines into production and to expand reserves at existing mines. The Bisha Mine has an estimated 9.5-year mine life remaining. There is no assurance that Nevsun will be able to maintain or increase its annual production, bring new mines into production or expand the mineral reserves and mineral resources at its existing mine.

Permitting risk. The Company’s operations and future development are subject to receiving and maintaining permits from appropriate governmental authorities and the granting of new exploration and other licenses and permits. There is no assurance that delays will not occur in connection with obtaining all necessary renewals of existing permits for current operations or exploration tenements, or for additional permits for any possible future changes to operations or applications for new exploration tenements, or additional permits associated with regulations and legislation. Prior to any development on any of its properties, the Company must receive permits from appropriate governmental authorities. There can be no assurance that the Company will obtain or continue to hold all permits necessary to develop or continue operating at any particular property site. Any failure to obtain or maintain the requisite permits could have a material adverse effect on the Company and its future production levels.

Environmental risk. Production at the Company’s mine involves the use of toxic materials. Should toxic materials leak or otherwise be discharged from the containment system then the Company may

become subject to liability for cleanup work that may not be insured against. While the Company intends to prevent discharges of pollutants into the ground water and the environment, it may be unsuccessful in such efforts and as a result may become subject to liability for hazards that it may not be insured against. Losses from these events may cause the Company to incur significant costs that could have a material adverse effect upon its financial performance and results of operations.

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 over time. 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 devotes significant time and resources toward meeting its goal of complete compliance with all environmental regulations in the countries in which the Company has operations and seeks to comply with prudent international standards.

Environmental hazards may also exist on the properties on which the Company holds interests that are unknown to the Company at present and that may have been caused before the Company received title to the properties.

Failure to comply with applicable laws, regulations and permitting requirements may result in enforcement actions, including orders issued by regulatory or judicial authorities causing operations to cease or be substantially curtailed, and may include corrective measures requiring significant capital expenditures, installation of additional equipment, or remedial actions. In addition, parties that engage in mining operations, including the Company, may be required to compensate those suffering loss or damage by reason of the mining activities and may face civil or criminal fines or penalties for violations of applicable laws or regulations.

Amendments to current laws, regulations and permits governing operations and activities of mining companies, or more stringent implementation thereof, could have a material adverse impact on the Company and cause increases in exploration expenses, capital expenditures or production costs, reduction in levels of production at producing properties, or abandonment or delays in development of new mining properties.

Labour risk. The Company is dependent on its workforce to extract and process minerals, and is therefore sensitive to its ability to source skilled labour in country and the potential for a labour disruption that impacts the Company's mining activities or changes to laws. The Company endeavours to maintain good relations with its workforce in order to minimize the possibility of strikes, lockouts and other stoppages at its work sites. Relations between the Company and its employees may be impacted by changes in labour relations that may be introduced by, among other things, employee groups, unions, and the relevant governmental authorities in those jurisdictions where the Company operates.

Risks related to the construction, plant expansion, transition to zinc phase at Bisha, optimization of current process plant, and start-up of new mining operations or mining phases. The success of construction projects, plant expansions and their optimization, the transition to primary production at Bisha or the start-up of new mines by the Company is subject to a number of factors including the availability and performance of qualified engineering and construction contractors, mining contractors, suppliers and consultants, the receipt of required governmental approvals and permits in connection with the construction of mining facilities and the conduct of mining operations, including environmental permits, price escalation on all components of construction, plant expansion, transition to primary production or start-up of new mines, the underlying characteristics, quality and unpredictability of the exact nature of mineralogy and metallurgy of a deposit and the consequent accurate understanding of doré or concentrate production, the successful completion and operation of conveyors to move ore and other operational elements. Any delay or deterioration in the performance of any one or more of the contractors, suppliers, consultants or other persons on which the Company is dependent in connection with its construction, expansion or transition activities or start-up of new mines, a delay in or failure to receive the required governmental approvals and permits in a timely manner or on reasonable terms, or a delay in or failure in connection with the completion and successful operation of the construction or

59 | Nevsun Resources Ltd.

ANNUAL INFORMATION FORM – December 31, 2015

operational elements could delay or prevent the construction projects, plant expansions, the transition to primary production at Bisha as planned, or the start-up of new mines. There can be no assurance that current or future construction projects, plant expansions, the transition to primary production at Bisha as planned or the start-up of new mines by the Company will be successful.

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. Disruption or curtailment of access to or maintenance of such infrastructure or supplies whether it is due to inclement weather, wear and tear, or other reasons, could have an adverse material impact on the Company’s ability to service and operate its mines due to higher costs or business interruption. Unusual or infrequent weather phenomena, sabotage, terrorist activities, 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.

Transportation risk. Delivery to the mine operation of required operating consumables and fuel as well as delivery to the various smelters of mine-produced concentrates is most often subject to third party contractors, be it land transport in country or sea freight to and from the ocean port. To a large extent there are many factors outside the control of the Company, which can adversely affect the delivery of these key commodities and consumables, or the export of these metal concentrates ranging from elevated transport costs to significant delays or temporary stoppage in product movement. The Company may be unable to achieve efficient transportation logistics when seeking to move copper or zinc concentrate from the mine site to port. There remains a risk that the contractor will not be able to transport the required volume of concentrate due to various factors such as an inadequate number of trucks, poor maintenance of those trucks, or an inadequate number of trained drivers available to operate the trucks. In addition, there may be difficulties in chartering marine bulk carriers into Massawa in a timely manner to transport concentrate from the port of Massawa to overseas customers. There is also an ever-present risk of piracy with respect to marine transport in and around the Gulf of Aden and the risk that the port of Massawa could become inaccessible in the event of piracy, military conflict or political unrest. Any interruption in the delivery chain from mine site to customers could both halt mine process plant production due to limited storage capacity for concentrates (as well as risks associated with build-up of concentrate stocks exposed to the elements) leading to business interruption losses which could also breach the terms and conditions of certain offtake agreements that may specify delivery of required quantities of concentrate over pre-established time periods. These factors could have a material impact on the Company’s results of operations and financial condition.

Land title risk. The acquisition of clear title to mineral properties is a very detailed and time-consuming process. Title to, and the area of, mineral concessions may be disputed. Although the Company believes that it has taken reasonable measures to ensure receipt of proper title to its properties, there is no guarantee that title to any one or more of its properties will not be challenged or impaired. Third parties may have valid claims underlying portions of the Company’s interests, including prior unregistered liens, agreements, transfers or claims, including indigenous land claims, and title may be affected by, among other things, undetected defects. In addition, the Company may be unable to operate its properties as permitted or to enforce its rights with respect to its properties while such title defects or claims are addressed.

Other Risks and Uncertainties. The Company is subject to a number of other risks and uncertainties that could adversely affect the Company’s business, financial condition and operating results and its beliefs, plans and expectations about the future including, without limitation, risks that: (i) the Company becomes involved in any material disputes with any of its key business partners, suppliers or customers; (ii) the Company is subject to any adverse ruling in any of the pending litigation to which it is a party; (iii) the Company incurs unanticipated power interruptions or failures due to electrical circuit failures or inadequate fuel quality or continued supply required to effectively operate power generators for the plant or otherwise, the short supply or high cost of fuel and energy; (iv) fluctuating trends in the supply and cost of parts or fuel can make planning our business more difficult; or (v) unexpected costs or repairs to the plant; or (iv) the Company experiences challenges with copper mineralogy or host pyrite minerals that impacts metallurgical recoveries and concentrate grades in the transition zone.
