IAMGOLD CLARIFIES IMPACT OF MINING CODE REVISIONS IN BURKINA FASO

Toronto, Ontario, July 6, 2015 - IAMGOLD Corporation ("IAMGOLD" or the "Company") provides clarification regarding the vote by the Transitional Assembly on an updated Mining Code in Burkina

Faso. While the Code has not yet been formalized into law, it reduces regulatory uncertainty, creates an innovative community development fund, and, importantly, respects clauses in existing Mining Conventions. As a result, IAMGOLD does not expect a material impact on its Essakane Mine, as it has fiscal stability clauses in its existing Mining Convention.
