TSX Trading Symbol: IMG NYSE Trading Symbol: IAG ASX Trading Symbol: IGD BSE Trading Symbol: IAMGOLD Fully Diluted Shares Outstanding: 179.0 MM TORONTO, June 8 /PRNewswire-FirstCall/ -- IAMGOLD Corporation ("IAMGOLD" or "the Company") is pleased to announce the results of an additional 31 diamond drill holes on its 100% owned Quimsacocha project in Ecuador, including an intersection of 37.2 metres averaging 46.1 grams per tonne (g/t) gold, 89.2 g/t silver and 1.8% copper in hole 278. The Quimsacocha property is located 40 kilometers southwest of the city of Cuenca in southern Ecuador. These results are from the 2006 drill program to date and total 5,929 m of diamond drilling at the property. Joseph Conway, President and CEO of IAMGOLD commented on the most recent drill results: "These results continue to be encouraging and demonstrate the continuation of this resource beyond the established base of 2.8 million ounces. The results also indicate the lateral continuity of the orebody southwards and confirm the presence of a very high grade zone to the north. The relationship between structures and the very high grade mineralization is to be the subject of further drill testing. Ongoing surface mapping of alteration and geology combined with a reinterpretation of geophysical data suggests potential for further extensions of the Quimsacocha system to the south, west and north with a number of new targets identified for drill testing in the second half of 2006." The drill program for the remainder of 2006 at Quimsacocha will continue to infill drill and test new targets within 1.5km of the existing orebody to further delineate the resource. Planned spending in the second half of 2006 at Quimsacocha will be US$3.8 million. The significant results are shown in Table 1. The collar locations of the drill holes can be found in Figure 1 at http://files.newswire.ca/396/iamg.doc. Additional figures can be found at: http://www.iamgold.com/.
