Eastmain Resources Inc. (TSX - ER) announced the start of its 2007 exploration program for its MEGATEM JV, a joint venture with Xstrata Copper Canada ("Xstrata"), located in the Normetal-Detour areas of Ontario and Québec.

The MEGATEM Project covers about 14,500 square kilometres of the Abitibi Greenstone Belt, west of the Québec border and north of Lake Abitibi. The Abitibi Greenstone Belt is world renown for its gold, copper, zinc and nickel deposits. In 2004, state-of-the-art airborne geophysical technology detected over 200 geophysical anomalies in the project area. To date, 46 of these airborne anomalies have been followed-up by ground or additional airborne geophysical surveys and of these, 35 targets have been drill tested.

The 2007 program will further define five targets located in St Laurent, Bradette, Tomlinson and Abbotsford townships. In St Laurent township, MEGATEM conductors suggest a 400-metre extension of the Patten River Nickel showing, where historically ASARCO reported intersections of 0.33% Cu and 0.37% Ni over 19.2 metres in drill hole PA-5, and 0.16% Cu and 0.23% Ni over 26.5 metres in drill hole PA-7. The St Laurent target also has platinum group element (PGE) potential however, no historical assays for PGE’s have been located. The other four targets were identified using Xstrata’s proprietary Geographic Expert System (GES), which systematically integrates various geological and geophysical datasets including airborne magnetics, MEGATEM conductors, bedrock geology and historical drill data. All five targets are buried under thick deposits of gravel, sand and clay and therefore rely heavily on geophysical detection. These targets have been validated against previous work and possibly reflect volcanogenic massive sulphide, copper-zinc or iron formation hosted gold mineralization.

Fugro Airborne Surveys of Ottawa, Ontario has been contracted to survey the five targets using a HeliGEOTEM II system, which combines the greater horizontal resolution and flexibility of helicopter mounted time-domain EM systems with the proven GEOTEM / MEGATEM technology. The HeliGEOTEM II survey work is underway and is designed to resolve the 2004 MEGATEM conductor anomalies so that drill targets can be located. A helicopter supported drilling program, totalling about 1000 metres, will follow once the new data has been evaluated.

Dr. Donald Robinson, P. Geo. is the qualified person supervising the project.
