IAMGOLD's Westwood Resource Grows 128%

Toronto, Ontario, Tuesday June 19, 2007 - IAMGOLD Corporation ("IAMGOLD" or "the Company") is pleased to announce a revised resource estimate at the Westwood exploration project located on the Cadillac Break in the Abitibi region, 40 km east of Rouyn-Noranda in the Bousquet township in northern Quebec, close to the Company's Doyon operation.  The estimate is based on close to 140,000 m of drilling in 182 drill holes, and includes drilling up to and including the most recent results press release dated June 13, 2007.  The resource estimate identifies an inferred resource of 14.1 million tonnes of ore at an average grade of 7.3 g/t Au indicating 3.3 million ounces of gold. 

This revised resource estimate shows a 96% increase in tonnage, 16% increase in grade with a 128% increase in ounces of gold from the previous undiluted resource estimate released in 2004.  Since that time, the on-strike extension of three zones has resulted in a significant increase in the inferred resource.  The gold mineralization has not been completely delimited, and is open at depth and along strike.

"We are very pleased with the more than doubling of this resource and because of the potential size, we are now looking at Westwood as a new project," stated Joseph Conway, President and CEO.  "Much of the prospective area within this camp has not yet been drilled, particularly at depth and we expect continued positive results.  In August, we will complete a scoping study on the viability of sinking a shaft from surface to access this mineralization, a step closer to realizing this component of our growth potential."

The resource estimate was calculated using information from 126 surface and 56 underground diamond drill holes within a 2.5 kilometre corridor between the Doyon Mine and the eastern limit of the Company's property. The new resource estimate includes drilling from the Westwood and North Corridor zones, the extension of these zones, and the Zone 2 extension west of the Bousquet fault.  The distance between drill holes varies from 100 to 200 metres. A 40 g/t Au top cut was used in the estimation, tonnages were based on densities of 2.85 to 2.90 tonnes / cubic metre and the minimum true width used in the estimation is 3.0 metres.   Table 1 presents the resource at various cut off grades.

The 2007 Westwood program is estimated at more than US$5 million to advance the exploration drift and complete 25,000m of drilling to further explore and define the resources.  This estimate is a component of the Scoping Study initiated by the Company's Project Development group to evaluate the economic potential of this resource.  Results from this study are expected in August, 2007.
