Eastmain Resources Inc. (ER:TSX) is pleased to announce that drilling is underway at its MegaTEM project located in the Normetal-Detour areas of Ontario and Québec, a joint venture with Falconbridge Limited (formerly Noranda Inc.). This phase will test 12 high-priority MegaTEM targets within the western extension of Abitibi greenstone belt - one of the most prolific mineral districts in the world, and host to a number of gold and base metal producing mines.

The partners delineated 225 isolated MegaTEM anomalies in their 2004 airborne survey. Detailed ground or airborne geophysical follow-up was completed on 46 priority targets. An additional 187 targets have also been identified as being prospective for base metal or gold deposits. Any one of these untested MegaTEM anomalies may be indicative of an orebody below.

Earlier this year the JV partners completed 23 drill holes for a total of 4,730 metres. Twenty-one of 23 drill holes intersected a sulphide source for the airborne anomaly. Down-hole (PEM) geophysical surveys were also completed on a number drill holes. PEM evaluates the possibility of conductive mineralization beyond the actual drill hole.

Three areas of interest have been identified to date; one area is prospective for gold and two display significant base metal potential. Drill hole TOM-102-05-01 intersected a 9.1-metre-thick carbonatebearing (ankerite) iron formation containing 0.45 g/t gold over 4.0 metres cored length. This hole tested a MegaTEM anomaly adjacent to a regional conductive trend within brecciated and sulphidebearing felsic volcanic rocks. The geology, ankerite alteration and gold mineralization intersected in TOM-05 make this target horizon highly prospective for gold deposits. A number of well-known gold deposits are associated with ankerite and sulphide-bearing volcanic rocks. This zone merits additional exploration. Other holes intersected zones prospective for gold mineralization which will be further evaluated by Eastmain.

VMS-style (volcanogenic massive sulphide) alteration and geology was identified with MegaTEM targets HUR-03, HUR-06 and HUR-07. Drilling cut iron sulphide mineralization within chloritesericite altered felsic volcanic rocks in each of these targets. This cluster of anomalies represents an area with increased potential for VMS-type copper-zinc discovery. An isolated MegaTEM anomaly (STL-03) coinciding with a nickel-copper prospect, located in St. Laurent Township, Ontario was detected from the 2004 survey. Fifty-Five claim units covering this prospect were staked by the JV partners. Previous drilling by Asarco Incorporated intersected a wide zone of nickel-copper sulphide grading 0.47% nickel and 0.36% copper across 24 metres in close proximity to a large magnetic anomaly. Additional work is also warranted on this prospect.

Mr. Dean F. Rogers, P. Geo, Senior Project Geologist, Falconbridge Limited is the qualified person supervising the project. Core samples were analysed at Swastika Laboratories in Northern Ontario.
