Exhibit 99.6

AUDITORS’ REPORT ON RECONCILIATION TO UNITED STATES GAAP

To the Board of Directors of IAMGOLD Corporation

On March 26, 2009, we reported on the consolidated balance sheets of IAMGOLD Corporation (“the Company”) as at December 31, 2008 and 2007 and the consolidated statements of earnings, comprehensive income and retained earnings and cash flows for each of the years in the three-year period ended December 31, 2008 which are included in or incorporated by reference in the annual report on Form 40-F. In connection with our audits of the aforementioned consolidated financial statements, we also have audited the related supplemental note entitled “Reconciliation with United States Generally Accepted Accounting Principles – Item 18” included in the Form 40-F. This supplemental note is the responsibility of the Company’s management. Our responsibility is to express an opinion on this supplemental note based on our audits.

In our opinion, such supplemental note, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.
