IAMGOLD completes redemption of long-term debt due in 2020

All monetary amounts are expressed in U.S. dollars, unless otherwise indicated.

TORONTO, April 3, 2017 /PRNewswire/ - IAMGOLD Corporation ("IAMGOLD" or the "Company") today announced that it has completed the early redemption of its $489 million of outstanding 6.75% Senior Notes due in October 2020 (the "Existing Notes").  The redemption was funded from the net proceeds of its recent issue of $400 million aggregate principal amount of 7.00% Senior Notes due in 2025 (the "Notes") and cash on hand.

"With this redemption and the issuance of a smaller amount of debt with an extended due date of April 15, 2025, our capital structure continues to support our ability to fund our growth pipeline," commented Carol Banducci, Executive Vice President and CFO.  "Investors should note that the timing of today's redemption occurs after the end of the first quarter 2017.   Therefore as of March 31, 2017, both issues of debt were outstanding coupled with a higher pre-redemption cash balance.  By extending the maturity of $400 million of debt to 2025, the Company has significantly enhanced its ability to fund its pipeline of internal growth opportunities."
