TORONTO, ONTARIO--(CCNMatthews - July 25, 2007) - IAMGOLD Corporation (TSX:IMG)(NYSE:IAG)(BSE:IAMGOLD) ("IAMGOLD" or "the Company") is pleased to announce a new resource estimate and exploration update for the Buckreef Project in the Lake Victoria Goldfields Region of northern Tanzania. The measured and indicated resource base now consists of 16.7 million tonnes at an average grade of 1.9 g/t Au for 1.0 million ounces of gold and represents an increase of 9% from resources reported on December 31, 2006(a). At a 1.0 g/t cut off, the total measured and indicated resources on the Buckreef project contain 16 million tonnes at an average of 1.9 g/t Au for 1.0 million ounces Au and an inferred resource of 10.9 million tonnes with 2.4 g/t Au for 0.8 million ounces Au.
"These results further our understanding and confidence in this resource," commented Joseph Conway, President & CEO. "With continued exploration and resource development, including the evaluation of processing options, this project is moving toward the pre-feasibility stage of development. We expect to announce the initiation of a pre-feasibility study before the beginning of 2008."
The resource update incorporates new drill results from 37,734 meters of RC drilling and 1,876 meters of diamond drilling on the project that were completed between August 2006 and April 2007. The majority of the resource increase can be attributed to the Buziba area where drilling defined additional mineralization to the south and north of previously reported resources. The resource estimates were prepared by Hellman & Schofield Pty Limited, based in Perth, Australia. Details of the updated resource estimates are presented in Table 1.

Exploration Update
The Buckreef Project has an extensive land package totaling more than 260km2, encompassing 40km of strike on the prospective Rwamagaza Greenstone Belt. The Belt is largely covered by 5 to 15m of overburden, which masks the underlying host rocks and any mineralization, and has not been fully explored with modern exploration methods. Generative work using advanced techniques outside of the resource areas in the last 6 months has defined multiple targets, which have been prioritized for testing in the next 6 months.
Late in 2006 aircore drilling was initiated at a newly identified target located within the Buckreef project area. Follow-up aircore and RC drilling was carried out early in 2007 confirming the reconnaissance drill results. Results from drilling include an 19 metre intersection averaging 6.7 g/t Au. Mineralization occurs below about 12 metres of overburden and has been defined over a strike length of approximately 500 metres and to a depth of 50 metres in the oxide zone. Mineralization is closed off along strike but is still open at depth. The significant assay results for this prospect are presented in Table 2.

(a)Notes: Intersections are calculated using average intercepts
with a minimum of 1.0g/t Au, minimum length of 1m with maximum
internal dilution of 2m. All samples are RC with 1 meter sample
interval and 50 gram fire assay with AAS finish.
The mineralization is hosted in a wide steeply dipping shear zone. In the upper oxide zone the gold mineralization is up to 80 metres wide. Near the base of oxidation the mineralized zones are from 2 to 10 metres in true width. The mineralization is located in variably weathered and altered basaltic and felsic porphyry rocks.
Second Half Exploration Program
The work program for July to December 2007 on the Buckreef Project includes spending of US$3.2 million on exploration with 15,000 metres of aircore drilling, 7,000 metres of RC drilling and 1,975 metres of diamond drilling. This drilling is focused primarily on testing depth extensions to the new prospect, testing several drill targets identified beneath cover in the Buckreef, Bingwa and Tembo areas, and reconnaissance drilling on several new targets recently defined along the Rwamagaza Greenstone Belt. The diamond drilling is focused on collecting metallurgical samples for more detailed coarse ore leach test work of the Buziba and Busolwa deposits.
Metallurgical testing began in the first half of 2007 and continues on composite oxide and fresh ore samples from various areas within the Buckreef Project. Baseline testing includes a range of various processing routes to identify appropriate treatment methods and to generate preliminary project evaluation and engineering data.
