IAMGOLD Achieves Commercial Production at Essakane Effective July 16, 2010

TORONTO, ONTARIO -- (Marketwire) -- 08/19/10 -- All amounts are expressed in US dollars, unless otherwise indicated.

IAMGOLD Corporation ('IAMGOLD' or the 'Company') (TSX: IMG)(NYSE: IAG)(BOTSWANA: IAMGOLD) today announced that its Essakane gold mine in Burkina Faso has achieved commercial production effective July 16, 2010. The plant began to process material to test circuits in late June 2010, reaching the throughput, production and other operational standards to meet commercial production requirements beginning July 16, 2010. The plant has since met those performance criteria consistently for the necessary 30 consecutive days (the 'Start Up Period') to declare commercial production.

During the Start Up Period, the Essakane mine processed an average of more than 16,000 tonnes per day, exceeding the 60% hurdle rate of design throughput required to establish commercial production. Ramp up continues, and during the first half of August, the Essakane process plant has been operating at approximately 75% of design capacity. During the Start Up Period, the operation produced an estimated 17,400 ounces of gold that indicated a gold recovery rate above 95%, effectively at feasibility design levels. With the July 16, 2010 start date, Essakane is expected to produce 165,000 to 175,000 ounces of gold in 2010 (on a 100% basis) at a cash cost below $400 per ounce (including royalty). The Company currently expects that Essakane will produce an average of 315,000 ounces of gold per year at an average cash cost of between $400 and $410 per ounce over the initial mine life expectancy of 12 years, however, based on recent exploration success the Company expects to expand the project.

'Bringing a major gold development project into production is a noteworthy accomplishment at any time, and with Essakane, the Company's first African greenfield construction project, IAMGOLD has demonstrated another of its core competencies as a mature gold producer,' said President and CEO, Peter C. Jones. 'Including Essakane, IAMGOLD expects to produce between 980,000 and 1,010,000 ounces of gold in 2010. Essakane's startup also represents a milestone for Burkina Faso, representing the largest private foreign investment ever undertaken in that country and a significant economic driver for the country moving forward.'

The construction of the project cost approximately $453 million, involved over 3,000 people and adhered to international standards and best practices for all parts of the project. A total of 21.4 million tonnes of material were mined during the pre-production period. The startup of the project was six months ahead of initial predictions despite a number of challenges in logistics, climate, and manpower. An extensive training effort was required for both the construction labour force and the operations team, and continued training will be a key driver for success moving forward.

As of January 1, 2010, IAMGOLD estimated that Essakane had on an attributable basis 4.3 million ounces of measured and indicated resources (inclusive of 3.8 million ounces of reserves) and another 1.9 million ounces of inferred resources. Concurrent with the construction and start up of the operation, IAMGOLD is spending $15.8 million at Essakane during 2010 on resource development and exploration, including a recently allocated additional amount of $1.6 million. Over 80,000 metres of drilling is planned for 2010, with a primary focus on the north and south strike extensions of the Essakane main zone. This work is designed to identify new mineral resources on IAMGOLD's vast exploration land package and support future production increases.

Gordon Stothart, Executive Vice President and COO of IAMGOLD commented, 'We are extremely proud of the team that has brought this challenging project into production ahead of schedule. We continued to meet our commitment to Zero Harm with ten lost time accidents in over 11 million hours worked, a lost time injury frequency of 0.18 which compares favourably to world-class standards. Also in step with this commitment, IAMGOLD completed a successful relocation of the Essakane village, which involved the construction of more than 2,000 buildings to provide 12,000 people with improved housing and access to clean water and enhanced education.

'Essakane is now a producing mine. For the first few years of the operation, we plan to process soft ore at the rate of 9.0 million tonnes per year. As of today, we have stockpiled 5.8 million tonnes of ore, equivalent to over eight months of production and we are currently on target to fill the water reservoirs with between 3.5 million and 4.0 million cubic metres of water, which we expect to be more than sufficient to meet our production needs during the dry season. We have a 27.5 megawatt power plant and have a tailings storage facility with the capacity to accommodate all of the current life of mine requirements. Essakane will make a strong contribution to IAMGOLD's production, earnings and cash flow.'

BACKGROUND

The project began construction in September 2008. IAMGOLD acquired a 90% interest in the Essakane mine as a development project on February 25, 2009, with the Burkina Faso government holding the remaining 10%.

The Essakane property is located in north-eastern Burkina Faso, West Africa, and consists of six exploration permits covering approximately 1,283 square kilometres. The Essakane main zone deposit (the 'EMZ deposit') is located in the 100 square kilometre mining concession, centered within the block of exploration permits.
