IAMGOLD SIGNS OPTION FOR SALE OF SLEEPING GIANT

Toronto, Ontario, October 9, 2007 – IAMGOLD Corporation (“IAMGOLD” or “the Company”) is pleased to announce that an option agreement has been signed with Cadiscor Resources Inc. (“Cadiscor”) granting them the right to purchase the Sleeping Giant Mine (“Sleeping Giant”) after the completion of mining and processing for total consideration of up to CDN$7 million.  Sleeping Giant is a 100% owned IAMGOLD producing mine located in the Abitibi region of Northern Quebec.  Current estimated annual gold production is 50,000 ounces and it is expected to continue production through 2008.

In the deal reached with Cadiscor Resources, IAMGOLD will continue to mine and process reserves at Sleeping Giant until the end of its current reserve life at which time, Cadiscor will purchase the property and all the related infrastructure assets.  Under the agreement, Cadiscor Resources will pay CDN$300,000 in cash and issue 600,000 common shares of Cadiscor and 1 million common share purchase warrants to IAMGOLD and upon exercise of the option to purchase Sleeping Giant, will pay CDN$5 million in cash or Cadiscor common share equivalent less the maximum allowable discount.  In other parts of the agreement, IAMGOLD will also receive CDN$1 million in cash or Cadiscor common share equivalent after 300,000 tonnes of ore from any source are processed through the mill and will retain an NSR royalty on future production from Sleeping Giant.

“Cadiscor’s key asset, the Discovery Project, located relatively close to Sleeping Giant in Northern Quebec, could greatly benefit from the acquisition of the Sleeping Giant assets and will ensure the continuation of opportunity in this region of Northern Quebec,” commented Joseph Conway, President & CEO, IAMGOLD. “Our belief in the potential success of Cadiscor, its Discovery Project and exploration at Sleeping Giant, will benefit IAMGOLD shareholders through the equity position of Cadiscor acquired through this transaction.  We are very pleased with this arrangement and wish Cadiscor Resources much success.”

The agreement has been signed with the formal closing to occur within the fourth quarter.  It is expected that the option should be exercised late next year but no later than April 1st, 2009.
