C$6.00 PER NEVSUN SHARE

1178180 B.C. Ltd. (the “Offeror”), a wholly owned subsidiary of Zijin Mining Group Co. Ltd. (“Zijin Mining”), hereby gives notice that it has varied its offer dated September 14, 2018 (the “Original Offer”) to purchase, on the terms and subject to the conditions of the Original Offer, all of the issued and outstanding common shares (the “Nevsun Shares”) of Nevsun Resources Ltd. (“Nevsun”), together with any SRP Rights issued under the Shareholder Rights Plan, including Nevsun Shares that may become issued and outstanding after the date of the Original Offer but prior to the Expiry Time (as hereinafter defined) upon the exercise, conversion or exchange of any Convertible Securities in order to, among other things, amend certain terms and conditions of the Original Offer. The Original Offer, as varied hereby, is referred to herein as the “Offer”.

The Offer is open for acceptance until 5:00 p.m. (Toronto time) on December 28, 2018 (the “Expiry Time”), unless the Offer is accelerated, extended or withdrawn by the Offeror.

Nevsun Board of Directors’ Recommendation

The Board of Directors of Nevsun has UNANIMOUSLY determined that the Offer is in the best interests of Nevsun and is fair, from a financial point of view, to the Shareholders. The Board of Directors of Nevsun UNANIMOUSLY RECOMMENDS that Shareholders ACCEPT the Zijin Mining Offer.

This Notice of Variation should be read in conjunction with the Original Offer and the accompanying take-over bid circular dated September 14, 2018 (the “Original Circular” and together with the Original Offer, the “Original Offer and Circular”). The Original Offer and Circular and this Notice of Variation together constitute the “Offer and Circular”. Except as otherwise set forth herein, the terms and conditions previously set forth in the Original Offer and Circular, Letter of Transmittal and Notice of Guaranteed Delivery continue to be applicable in all respects. All references to the “Offer” in the Original Offer and Circular, the Letter of Transmittal, the Notice of Guaranteed Delivery and this Notice of Variation mean the Original Offer as amended hereby, and all references in such documents to the “Circular” or the “Offer and Circular” mean the Original Offer and Circular as amended hereby. Unless the context requires otherwise, capitalized terms used in this

2

Notice of Variation but not defined herein that are defined in the Original Offer and Circular have the respective meanings ascribed thereto in the Original Offer and Circular.

Shareholders who have validly deposited and not withdrawn their Nevsun Shares need to take no further action to accept the Offer and receive the Offer price of C$6.00 per Nevsun Share. Registered Shareholders who wish to accept the Offer must properly complete and execute the Letter of Transmittal, and deposit it, together with the certificate(s) or Direct Registration System statement(s) (“DRS Statements”) representing their Nevsun Shares in accordance with the rules and instructions in the Letter of Transmittal. See Section 3 of the Original Offer, “Manner of Acceptance - Letter of Transmittal”. Alternatively, Shareholders may accept the Offer by following the procedures for: (i) book-entry transfer of Nevsun Shares set out in Section 3 of the Original Offer, “Manner of Acceptance - Book-Entry Transfer”, or (ii) guaranteed delivery set out in Section 3 of the Original Offer, “Manner of Acceptance - Procedure for Guaranteed Delivery”, using the accompanying Notice of Guaranteed Delivery. Shareholders may continue to use the original Letter of Transmittal (printed on pink paper) or the original Notice of Guaranteed Delivery (printed on green paper) to accept the Offer, in which case the original Letter of Transmittal or the original Notice of Guaranteed Delivery, as the case may be, shall be deemed to be amended to reflect the terms and conditions of the Original Offer, as amended by this Notice of Variation.

Persons whose Nevsun Shares are held in an account with a broker, investment dealer, bank, trust company or other intermediary should contact their representative if they wish to accept the Offer, in order to take the necessary steps to be able to deposit such Nevsun Shares under the Offer. Intermediaries likely have established tendering cut-off times that are prior to the Expiry Time. Shareholders must instruct their brokers or other intermediaries promptly if they wish to tender.

No broker, dealer, salesperson or other Person has been authorized to give any information or make any representation other than those contained in this document, and, if given or made, such information or representation must not be relied upon as having been authorized by the Offeror, the Depositary (as defined below), or Information Agent (as defined below).

Shareholders will not be obligated to pay any fee or commission if they accept the Offer by transmitting their Nevsun Shares directly to Computershare Trust Company of Canada (the “Depositary”) at the address shown in the Letter of Transmittal, Notice of Guaranteed Delivery and on the last page of this document. However, an Intermediary through which a Shareholder owns Nevsun Shares may charge a fee to tender any such Nevsun Shares on behalf of the Shareholder. Shareholders should consult such Intermediary to determine whether any charge will apply.

Additional copies of this Notice of Variation, the Original Offer and Circular, the Letter of Transmittal and the Notice of Guaranteed Delivery may be obtained without charge on request from the Information Agent at its address shown on the last page of this document. Copies of this document and related materials may also be found on SEDAR and EDGAR under the Offeror’s profile at www.sedar.com and www.sec.gov.

NOTICE TO HOLDERS OF CONVERTIBLE SECURITIES

Any such exercise, conversion or exchange must be completed sufficiently in advance of the Expiry Time to assure that the holders of such Convertible Securities will have Nevsun Share certificate(s) or DRS Statement(s) representing the Nevsun Shares issuable upon such exercise, conversion or exchange in time for deposit prior to the Expiry Time, or in sufficient time to comply with the procedures referred to in Section 3 of the Original Offer, “Manner of Acceptance - Procedure for Guaranteed Delivery”.

NOTICE TO SHAREHOLDERS IN THE UNITED STATES

THIS TRANSACTION HAS NOT BEEN APPROVED OR DISAPPROVED BY THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION (“SEC”) OR ANY STATE SECURITIES COMMISSION NOR HAS THE SEC OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THE OFFER AND THE CIRCULAR. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

The Offer is made for the securities of a foreign issuer. The Offer is subject to Canadian disclosure requirements and Shareholders should be aware that these disclosure requirements are different from those of the United States.

The enforcement by Shareholders of civil liabilities under United States federal securities laws may be affected adversely by the fact that each of Nevsun, the Offeror and Zijin Mining are located in a foreign country, and that some or all of their officers and directors are residents of a foreign country. In addition, it may be difficult for Shareholders in the United States to enforce their rights and any claims they may have arising under United States federal and state securities laws since each of the Offeror and Nevsun is a corporation existing under the laws of British Columbia, Canada and Zijin Mining is a corporation existing under the laws of the People’s Republic of China; some or all of the officers and directors of each of the Offeror, Zijin Mining and Nevsun reside outside the United States; and all or a substantial portion of the assets of the Offeror, Zijin Mining and Nevsun are located outside the United States. Shareholders may not be able to sue the Offeror, Zijin Mining, Nevsun or their respective officers or directors in a foreign court for violations of United States federal securities laws. Further, it may be difficult to compel a foreign company and its affiliates to subject themselves to the jurisdiction and judgement of a United States court.

Shareholders should be aware that, during the period of the Offer, the Offeror or its affiliates may, directly or indirectly, bid for or make purchases of Nevsun Shares, or other securities of Nevsun, in each case, as permitted by applicable Law or regulations.

Nevsun shareholders in the United States should be aware that the disposition of Nevsun Shares by them as described herein may have tax consequences both in the United States and in Canada. Such consequences may not be fully described herein and such holders are urged to consult their tax advisors. See “Certain Canadian Federal Income Tax Considerations” in Section 18 of the Original Circular, and “Certain United States Federal Income Tax Considerations” in Section 19 of the Original Circular.

The foregoing conditions are for the exclusive benefit of the Offeror. Subject to Laws, the Offeror may assert any of the foregoing conditions at any time, regardless of the circumstances giving rise to such assertion.

The Offeror may waive any of the foregoing conditions in its sole discretion, in whole or in part, at any time and from time to time, at or prior to the Expiry Time, without prejudice to any other rights which the Offeror may have. Each of the foregoing conditions is independent of and in addition to each other of such conditions and may be asserted irrespective of whether any other of such conditions may be asserted in connection with any particular event, occurrence or state of facts or otherwise. The failure by the Offeror at any time to exercise or assert any of the foregoing rights shall not be deemed to constitute a waiver of any such right, the waiver of any such right with respect to particular facts or circumstances shall not be deemed to constitute a waiver with respect to any other facts or circumstances, and each such right shall be deemed an ongoing right which may be asserted at any time and from time to time by the Offeror. Subject to Laws, any determination by the Offeror concerning any event or other matter described in the foregoing conditions will be final and binding for all purposes.
