The exchange of Tenke shares for Lundin Mining shares and cash is considered a taxable event for Canadian income tax purposes. However, it is possible to defer some or all of any tax resulting from the share exchange by filing, jointly with Lundin Mining, a Section 85 Tax Election Form, and submitting the Tax Election Form to the Canada Revenue Agency.

The tax election form may be submitted to Lundin Mining via the website noted above or via mail or courier to: Lundin Tax Election Process, 250 Howe Street, Suite 200, Vancouver, B.C., V6C 3S7.

The deadline for submission of the tax election form to Lundin Mining is October 15, 2007. All eligible holders who wish to make a Section 85 election should give their immediate attention to this matter, and in particular should consult their tax advisors without delay.

Any eligible holder who does not ensure that Lundin Mining receives the holder’s completed Section 85 form(s) before October 15, 2007 cannot be assured of benefiting from the rollover provisions of the Income Tax Act (Canada) (or the corresponding provisions of any applicable provincial tax legislation).
