IAMGOLD Intercepts Westwood Mineralization at Depth

TORONTO, ONTARIO--(Marketwire - Dec. 5, 2007) - IAMGOLD Corporation ("IAMGOLD" or "the Company") (TSX:IMG)(NYSE:IAG)(BOTSWANA:IAMGOLD) is pleased to announce results from 5 drill holes of the ongoing drill program at the Westwood project, an advanced stage exploration project located within the Company's Doyon mine property in the Abitibi region of Northern Quebec.

These results include intercepts of the Zone 2 extension at a vertical depth of approximately 2.3 kilometers in hole R14281B-07, which is 800 metres deeper than mineralization previously intersected. This hole was specifically planned to test the depth potential and includes 10.0 metres averaging 11.5 grams per tonne (g/t) gold and 5.0 metres averaging 23.0 g/t gold. These results are significant given the depth of the known 3.3 million ounce resource previously delimited which is less than 1.5 kilometres.

The first hole east of the Bousquet Fault, hole R14404-07 also intercepted the Zone 2, a 3.0 metre intercept averaging 10.2 g/t gold and narrow massive sulphide mineralization, a 2.0 metre intercept of 3.6 g/t gold, 5.0% zinc, within the Westwood horizon.

These higher grade intercepts and intercepts at depth may have significant impact on the strike length and have potential to substantially increase the total Westwood resource.

"These results are some of the best to date on the Westwood project. With the increasing gold grades at this depth we are very encouraged that Westwood could become a world class deposit," commented Joseph Conway, President & CEO. "The acceleration of this project in 2007 will continue in 2008 and the results to date continue to confirm that Westwood will be IAMGOLD's future in Northern Quebec."

Significant intersections from this drilling campaign can be found in Table 1 with a longitudinal section of Zone 2 shown in Figure 1. These holes represent 7,050 metre of drilling since September 1, 2007 for a total of 25,000 metre of drilling this year.

In January 2008, valuation drilling on Zone 2 will begin. This will involve the drilling of a 400 metre by 400 metre block or panel, to demonstrate the continuity of the deposit. In addition, work will continue on the southern exploration drift toward the mineralized zones, which will be reached in the first quarter of 2008. More information is shown on Figure 2.

Qualified Person / Quality Control Notes

The drilling program was carried out by IAMGOLD employees, under the supervision of Ms. Nicole Houle, Geologist - Doyon Division. Ms. Houle is a qualified person (as defined by National Instrument 43-101) with more than 20 years of experience in mine and exploration geology. IAMGOLD has established an Analytical Quality Assurance Program to control and assure the analytical quality of assays in its gold exploration. This program includes the systematic addition of blank samples, reject and pulp duplicates and internal material references (the "standards") to each batch of samples sent for analysis. Blank samples are used to check for possible contamination in laboratories, field duplicates allow the quantification of overall precision while standards determine the analytical accuracy. Samples were sent for assaying to Doyon's internal laboratory as a primary laboratory. Samples were assayed by fire-assay according to industry standards.
