IAMGOLD Corporation: Westwood Scoping Study Shows Positive Economics

TORONTO, ONTARIO--(Marketwire - Sept. 6, 2007) - IAMGOLD Corporation ("IAMGOLD" or "the Company") (TSX:IMG)(NYSE:IAG)(BOTSWANA:IAMGOLD) is pleased to announce the results of the internal scoping study regarding the Westwood project. Results from this baseline economic assessment confirm the potential for Westwood to significantly contribute to the Company's long term production profile.

With inferred resources of more than 3 million ounces and based on an average life of mine diluted grade of 6.2g/t, which assumes a 3 metre mining width, a 20% dilution factor and a 95% mining recovery, Westwood would be expected to produce 200,000 ounces of gold per year for approximately 15 years with production beginning in 2012.

"We are very pleased with the Westwood project preliminary economics which are based on conservative assumptions. Our intention is to accelerate our exploration efforts during 2007 and 2008 as well begin planning for shaft development in 2009. We continue to be encouraged with exploration results and the deposits remain open at depth," commented Joseph Conway, President and CEO of IAMGOLD.

Operating parameters assume a 2,800 tonnes per day processing facility and total operating costs (excluding pre-production or sustaining capital expenditures) of US$70.00 per tonne or US$360 per ounce. Pre-production capital expenditure is expected to total US$316 million of which $146 million is allocated to surface and shaft construction. Approximately $80 million would be spent on deferred development to ensure sufficient working positions. Diamond drilling would total $25 million and $28 million would be required for underground mining equipment. The remaining $37 million is allocated for other costs including corporate G&A and insurance.

The purpose of this scoping study was to establish economic viability based on conservative parameters. In addition to the positive impact of further resource development, the rate of return is expected to improve based on operating cost improvements. These improvements will primarily be realized through reductions in the assumed mining width, optimization of the development plan and incorporating access to the higher grade ore in the first years of the mine life. Capital expenditures will also be reviewed to ensure the use of the best technology and practices.

The shaft sinking is anticipated to begin in 2009. The immediate next steps include lateral development to establish mineralization continuity as well as further definition and exploration drilling.

Cautionary Note

This assessment is preliminary in nature, includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty that this preliminary assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Cautionary Note to U.S. Investors

The United States Securities and Exchange Commission (the "SEC") permits mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. We use certain terms in this press release, such as "mineral resources", that the SEC guidelines strictly prohibit us form including in our filings with the SEC.
