IAMGOLD ANNOUNCES

YEAR END GOLD RESERVES INCREASE 20% TO 9.6 MILLION OUNCES

AND NIOBIUM RESERVES INCREASE BY 36%

Toronto, Ontario, February 23, 2009 – IAMGOLD Corporation announces its 2008 year end Mineral reserve and resource statement.

Joseph Conway, President & CEO stated, “We are very pleased to announce that 2008 was an excellent year for IAMGOLD in terms of reserve renewal at all of our continuing operations.”

IAMGOLD’s total proven and probable reserves increased by 20% or 1.6 million ounces to 9.6 million ounces as at year end 2008, compared with a year earlier.  Including depletion of 1.1 million ounces attributed to 2008 gold production, reserves increased by 2.7 million ounces.  The main contributors to the increase are the Rosebel Mine and the Quimsacocha project, although reserve replacement was achieved at all continuing IAMGOLD operations.  Upon the closing of the acquisition of Orezone Resources Inc. (“Orezone”), scheduled for February 25, 2009, an additional 3.1 million ounces using a $600 per ounce gold price (or 3.4 million ounces using a $700 per ounce gold price) related to the Essakane project in Burkina Faso will be added to IAMGOLD’s proven and probable reserves.

At the Rosebel Mine in Suriname, in-fill and exploration drilling successfully increased proven and probable reserves 9% above replacement, contributing 639,000 new ounces to reserves.  The positive preliminary feasibility study at Quimsacocha released in July 2008 increased reserves by 1.7 million ounces, and with the new mining law in Ecuador officially in effect as of January 29, 2009, the Company anticipates work on the ground to recommence in the near future.

Niobium proven and probable reserves as at December 31, 2008 increased by 36% to 137,800 tonnes of contained Nb2O5.  This represents an 18 year mine life at current production rates and a production expansion plan is being reviewed.  Inferred resources were significantly increased as well, by the addition of 69,000 contained tonnes of Nb2O5, or a 72% increase. The significant increases to reserves and resources relate to the use of an increased long term price assumption for niobium (at levels 30% below the currently realized price) and the planned use of paste backfill technology that will facilitate expanded extraction ratios on the lower levels.

IAMGOLD’s measured and indicated gold resources (including reserves) as at December 31, 2008 of 22.8 million ounces compares to 22.7 million ounces a year earlier.  Decreases at the Quebec operations were expected as these operations are near the end of their mine lives and lack resource replacement.  At the Quimsacocha and Westwood development projects, decreases in measured and indicated resources relate to the application of higher cut-off grades as mining plans were refined.  These decreases were offset by increases at Rosebel and Sadiola as described below.

At Rosebel, measured and indicated resources (including reserves) increased by 1.4 million ounces to 9.7 million attributable ounces, or a 1.7 million ounces increase including depletion replacement.   This increase is driven by the successful infill and exploration drilling, the increase in gold price, and the removal of the impact of the Euro Ressources SA royalty.  Major increases were achieved at the currently producing Royal Hill pit where higher grade material was encountered at depth, and at the Pay Caro pit where infill drilling added ounces to the western extension.  Additional economic mineralization was discovered in lateral extensions and at depth at the Mayo deposit, where pre-stripping has commenced ahead of gold production later this year. At the Rosebel and “J” Zone deposits, resources were added as drilling along strike and at depth demonstrated continuity.  In 2009, an aggressive 90,000 metre drill program is planned to pursue additional priority targets along the favourable geological horizons in the immediate mine area.

At Sadiola, attributable measured and indicated resources increased by 46% from 1.6 million ounces to 2.3 million ounces, mainly due to adjustments related to the stockpiles, a lower cut off grade applied to the deep sulphide mineralization, and the addition of the Tambali South deposit.  Sadiola oxide reserves in the current pit are sufficient to support production through to the end of 2010. An additional 0.3 million attributed ounces in the measured and indicated resource category, not currently classified as reserves, could extend Sadiola’s mine life in a favorable gold market environment.  Studies of the deep sulphides have resulted in the application of a lower cutoff grade of 1.2 g Au/t which increases the deep sulphide measured and indicated resource by 0.4 million attributed ounces.  The deep sulphides have the potential to further extend the mine life and a new study is to be completed in Q4 2009.  Additional drilling of satellite targets such as at Tambali South and Sekokoto SE continues, with the goal of identifying additional resources.

Gold reserves and resources for the 2008 year-end statement were estimated using a $700 per ounce gold price (unless otherwise indicated on the Tables below).  For the 2007 year end reserve and resource statement, a $600 per ounce gold price for reserves and $700 per ounce gold price for resources, the same as for the current year (except for the non-IAMGOLD operated mines).

Joseph Conway added, “For 2009, we have planned aggressive drill programs  for Rosebel, Westwood, Niobec and Sadiola which we expect will continue to build our reserve profile.  The completion of our transaction with Orezone, scheduled for February 25th, increases our reserves by more than 30% related to the Essakane project in Burkina Faso, bringing our reserves to 12.7 million ounces.  All of these positive developments will continue to deliver value for our shareholders.”
