IAMGOLD issued the following announcement on March 14.

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 the Province of 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 common shares, first preference shares, second preference shares, debt securities, warrants, subscription receipts or any combination thereof of up to US $1 billion during the next 25 months in the United States and Canada, except for the Province of Quebec. 

The net proceeds from any such offerings may be used by the Company to fund on-going operations and/or capital requirements, reduce the level of indebtedness outstanding from time to time, fund capital programs, fund potential future acquisitions and for general corporate purposes. 

The Company filed this new preliminary base shelf prospectus with a view to maintaining financial flexibility but has no immediate intention to undertake an offering.
