- The financial strength to capitalize on opportunities arising from turbulent markets.

- A strong management team and an experienced board.

"The combination of HudBay and Lundin creates a company that is financially strong, has excellent internal growth projects, and has the size and strength to take advantage of opportunities over the next 18 months," said Phil J. Wright, president and chief executive officer of Lundin. "This arrangement is in the best interest of Lundin shareholders, and I look forward to making a contribution toward building what has the potential to be a major new Canadian mining house."

"We're excited to create a Canadian base metals company that we believe will be a major presence on the world stage," added Allen J. Palmiere, chief executive officer of HudBay. "We will continue to grow the company with discipline, and use its financial strength with a view to creating future value for all of our shareholders."

The proceeds of the private placement will be used to repay the loan. Completion of the private placement of the Lundin common shares is subject to the satisfaction of certain regulatory requirements.

BOARD RECOMMENDATION

The Transaction has been approved by the board of directors of Lundin (with interested directors abstaining), following the unanimous recommendation of a special committee comprised of independent Lundin directors.
