IAMGOLD has completed the acquisition of an additional 3% share in Soc d’Exploitation des Mines d’Or de Sadiola (SEMOS), which owns the Sadiola gold mine in Mali from the International Finance Corp. Joseph Conway, President and CEO said, “The acquisition of an additional 3% share in Sadiola illustrates the confidence we have in the future of this mine. IAMGOLD discovered the Sadiola deposit in 1996, it has already produced over 6 Moz of gold and we believe, based on our recent prefeasibility study, that with the addition of the Sadiola Deep Sulphide Project, Sadiola will produce between 400,000 and 500,000 oz/y of gold on a 100% basis from 2013 until the end of 2018, another contributor to our future growth profile.”

This acquisition follows the announcement made on November 2, 2009 and currently brings IAMGOLD’s share in SEMOS to 41%, representing approximately 144,000 oz of gold in 2009. Further to the terms of the existing SEMOS shareholders agreement, AngloGold Ashanti (AGA) has also acquired a 3% share in SEMOS. The remaining partner, the Republic of Mali, has until the end of March 2010 to elect whether it will take up its proportionate entitlement of 19.15% of the 6% share of SEMOS, by acquiring an equal 0.574% share from each of IAMGOLD and AGA on terms and conditions proportionately identical to those applicable to IAMGOLD and AGA
