IAMGOLD FILES PRELIMINARY BASE SHELF PROSPECTUS

FOR RENEWAL OF EXISTING FACILITY

Toronto, Ontario, June 30, 2011 – IAMGOLD Corporation (“IAMGOLD” or the “Company”) today announced it has filed a preliminary short form base shelf prospectus with the securities regulators in each province and territory of Canada except for Quebec and a corresponding registration statement with the United States Securities and Exchange Commission. These filings, when made final or effective, will allow the Company to make offerings of shares, warrants, debt securities, subscription receipts or any combination thereof of up to US$1 billion during the next 25 months in Canada, except for Quebec, and the United States. The proceeds from any such offerings may be used by the Company to further expand and develop its existing mines, advance its development projects, further explore and develop its mineral properties, fund working capital requirements or for other general corporate purposes.

This filing is a renewal of the Company’s existing base shelf prospectus that was never drawn on. The Company filed this preliminary base shelf prospectus to maintain financial flexibility but has no immediate intentions to finance.
