IAMGOLD 2005 OPERATING RESULTS UPDATE AND MALI YEAR-
END RESERVES AND RESOURCES



Toronto, Ontario, February 8, 2006 - IAMGOLD Corporation (“IAMGOLD” or “the Company”) announced today that the Company produced a total of 447,000 ounces of gold in 2005 at a weighted average cash cost of US$276 per ounce. While the Company’s total share of gold reserves at the four mines in which it has interests, as at June 30, 2005 (Tarkwa and Damang) and December 31, 2005 (Sadiola and Yatela), decreased modestly, resources increased substantially.

Joe Conway, President and CEO of IAMGOLD commented on the Company’s 2005 production results and share of gold reserves and resources, stating: “While 2006 production will increase over 2005, rising costs continue to have an impact and we are evaluating numerous options to mitigate these increasing costs. IAMGOLD’s overall resources increased significantly in the last 12 months primarily due to the addition of resources at Quimsacocha. Sadiola continues its track record of replacing production through the conversion of resources into reserves. Another increase to the Company’s reserves and resources will occur at the close of the Gallery Gold acquisition.”

*    Gold Institute cash cost is a non-GAAP measure, calculated in accordance with the Gold Institute Standard wherein cash cost equals the sum of cash operating costs inclusive of production-based taxes and management fees and may include certain cash costs incurred in prior periods such as stockpiling and stripping costs and may exclude certain cash costs incurred in the current period that relate to future production.
 
Total forecast 2006 production from the four mines in which IAMGOLD holds interests is 480,000 ounces at a cash cost of US$295 per ounce.



Discussion on Reserves
IAMGOLD’s share of combined total reserves from its mines is 3.9 million ounces (refer to Table 1) using a gold price of US$375 per ounce for the Tarkwa and Damang mines and US$400 per ounce for the Sadiola and Yatela mines and based on pit optimizations run at US$375 per ounce of gold and US$400 per ounce.

Tables 2 through 4 illustrate proven and probable reserves for both Sadiola and Yatela at December 31, 2004 and at December 31, 2005 at a US$350 per ounce and a US$400 per ounce gold price, respectively.

At the Sadiola mine, IAMGOLD’s portion of the proven and probable reserves from December 31, 2004 to December 31, 2005 increased by 32,000 ounces after mining 184,000 ounces during 2005. This was due to an increased gold price for the reserve calculation, and the addition of material from satellite pits. At Yatela, IAMGOLD’s portion of the proven and probable reserves decreased by 137,000 ounces, mainly due to mining depletion.

3


The sensitivity on proven and probable reserves for Sadiola and Yatela at various gold price assumptions is shown in Table 4. The sensitivity in ounces of gold at varying gold prices is minimal. At Sadiola this is primarily due to below pit resources that are part of the resource material currently undergoing a prefeasibility study as part of the Sadiola Deeps project. Only material existing lateral to the pit at various gold prices is included in this sensitivity analysis and these are limited. At Yatela it is a function of the mine life. Mining is almost complete and is taking place at the bottom of the pit. A large cut-back would be required to add additional ore tonnes at Yatela.

Discussion on Resources
As at December 31, 2005, IAMGOLD’s share of measured and indicated resources (which include reserves) at Sadiola totaled 2.2 million ounces of gold and at Yatela, including the Alamoutala and KW18 deposit, totaled 392,000 ounces. This represents a total increase of 756,000 ounces at Sadiola and Yatela, or 42% when compared to measured and indicated resources reported at December 31, 2004. At the Yatela mine, measured and indicated resources decreased by 104,000 ounces, mainly due to mining depletion. At the Sadiola mine, measured and indicated resources increased by 860,000 ounces due to the upgrading of inferred resources to indicated resources in the FE3, FE4 and Deep Sulphides. As at December 31, 2005, IAMGOLD’s share of inferred resources at Sadiola and Yatela were 2.1 million ounces, an increase of 90,000 ounces from December 31, 2004.
