IAMGOLD Increases Dividend by 33% and Provides Guidance for 2011 All Amounts, Including Dividends, are Expressed in US Dollars, Unless Otherwise Indicated

TORONTO, ONTARIO -- (Marketwire) -- 12/09/10 -- IAMGOLD Corporation ('IAMGOLD' or the 'Company') (TSX: IMG)(NYSE: IAG)(BOTSWANA: IAMGOLD) today reported that it has increased its annual dividend payment by 33% from $0.06 per share to $0.08 per share. The annual dividend will be paid on January 14, 2011 to shareholders of record as of the close of trading on December 24, 2010. In addition, the Company has provided guidance for 2011, with gold production expected to increase by approximately 20% over the current forecast production for 2010.

IAMGOLD's President and CEO, Steve Letwin said, 'The dividend increase reflects the confidence the board and management have in the current and future cash flows for the Company. We have a superior combination of assets and people, and when you couple that with our strong balance sheet and attractive opportunities, the outlook for growth is very positive.'

In 2011, IAMGOLD expects attributable gold production to be in the range of between 1.1 million and 1.2 million ounces of gold at a cash cost of between $565 and $595 per ounce, assuming an average spot price for gold of $1,300. For niobium the Company expects to produce between 4.7 million and 5.0 million kilograms of niobium at a margin of between $15 and $17 per kilogram.

As a further update to the status of the Essakane Mine in Burkina Faso, the electrical problem that occurred in November was fully rectified and the mine is operating at or above nameplate capacity. The land holding surrounding the current operations continues to exhibit significant upside potential and will be a focal point of the Company's 2011 exploration plans.

In future, the Company plans to pay its dividend semi-annually. For purposes of subsection 89(14) of the Income Tax Act, the Company designates all dividends payable on January 14, 2011 to be eligible dividends.
