TORONTO, ONTARIO–(Marketwired - Feb. 22, 2017) - Lundin Mining Corporation (“Lundin Mining” or the “Company”) (TSX:LUN)(OMX:LUMI) reports the following:

The Company is pleased to announce that today it has declared a dividend of CAD$0.03 per share. The dividend is payable on April 18, 2017 to the shareholders of record at the close of business on March 31, 2017. This dividend qualifies as an ‘eligible dividend’ for Canadian income tax purposes.

Notice to all Non-Canadian Resident Shareholders

In 2012, the Canada Revenue Agency (CRA) changed how the tax withholding rate applied to dividend payments made to non-residents is determined. The CRA now requires a certification of residency from each shareholder so that the preferred tax treaty rate can be applied where applicable to persons resident in countries which have a tax treaty with Canada.

Form NR301 form will be mailed to all Registered non-resident shareholders by Computershare Investor Services Inc. In order to receive the preferred treaty rate, you must complete and mail back the form as soon as possible. Failure to supply a completed NR301 form will result in Computershare withholding the statutory 25% withholding tax rate on any payments to Registered non-resident shareholders. You can also download the form at https://cda.computershare.com/Content/4f677775-5e6c-4e64-a695-a5785771fec3. Instructions on how to correctly complete the NR301 are on the back of the form. Shareholders who hold their shares through a broker should contact their broker directly. They do not need to return a form to Computershare.

Notice to all holders of Swedish Depository Receipts

The dividend is payable to those holders of SDBs (ISIN SE0001134529) (“SDRs”) who on the record date (March 31, 2017) are entered on the SDR register kept by Euroclear Sweden as holders of SDRs or holders of rights. Dividends payable to SDR holders shall be paid in Swedish kronor (SEK). The conversion from CAD$ to SEK will be executed by Pareto Securities AB (“Pareto”) at public market rate. The estimated payment date is on or about April 25, 2017.

In order to execute the payment of the dividend on the SDRs, a temporary administrative cross border transfer closure will be applied from and including March 28, 2017 up to and including March 31, 2017, during which period shares of the Company cannot be deposited with Pareto Securities AB and deposited shares of the Company cannot be withdrawn.

SDR holders who are entitled to reclaim Canadian and/or Swedish tax under applicable tax treaties should contact the CRA and the Swedish Tax Agency, respectively, directly.
