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

Toronto, Ontario, August 31, 2011 – IAMGOLD Corporation (“IAMGOLD” or the “Company”) today is pleased to announce that it has completed the sale of its Mupane Gold Mine in Botswana to Galane Gold Ltd. (“Galane”) (TSX-V: GG) (Galane formerly known as Carlaw Capital III Corp.).

IAMGOLD received total consideration of $34.2 million, after adjustments, consisting of $12.5 million in cash, $17.9 million in common shares of Galane Gold and a $3.8 million promissory note, payable over 3 years at an annual interest rate of 6%. For the equity portion of the consideration, IAMGOLD received an aggregate of 21,875,000 common shares of Galane representing approximately 48.5% of the outstanding shares of Galane. In addition, the Company received 1,265,253 warrants in Galane exercisable at C$1.10 per share for an 18 month period that, if exercised, could increase IAMGOLD’s beneficial interest in Galane to 49.9% of the outstanding shares.

Commenting on the sale, President and CEO Steve Letwin said, “Our strategy has been to focus on our core long-life assets that can provide the greatest potential for driving growth in production. Structuring the transaction in this way allows IAMGOLD to participate in the success of Mupane going forward. We are pleased that Galane will focus all of its efforts on Mupane and are confident that its team of operators, led by President and CEO Philip Condon will be effective at maximizing the value of Mupane for all shareholders. We look forward to the continued success of Mupane through our significant ownership interest in Galane.”

IAMGOLD acquired the shares pursuant to the terms of an amended and restated share purchase agreement and holds the securities for investment purposes.  IAMGOLD currently has no intention of acquiring ownership of, or control over, additional securities of Galane other than (i) additional warrants to preserve IAMGOLD’s 49.9% partially diluted interest if Galane completes its proposed acquisition of properties near Mupane and (ii) common shares of Galane that may be acquired by exercise of the warrants.  IAMGOLD expects to evaluate its investment in Galane on an ongoing basis and depending on such review, IAMGOLD may exercise its warrants, or otherwise increase or decrease its interest in securities of Galane in the future.

In addition to the share purchase agreement, IAMGOLD entered into: (i) a registration rights agreement with Galane, (ii) an escrow agreement with Equity Financial Trust Company, as escrow agent, and certain other security holders of Galane, and (iii) a lock-up agreement with Canaccord Genuity Corp.
