Eastmain Resources Inc. (TSX - ER)announces the start of an induced polarization (IP) geophysical survey on the Éléonore South property, located 12 kilometres southeast of Goldcorp’s Roberto deposit in the James Bay region of Québec. The project is a three-way joint venture with Les Mines Opinaca Ltée, a wholly owned subsidiary of Goldcorp Inc. (TSX: G, NYSE: GG) and Azimut Exploration Inc. (TSX Venture: AZM).

Induced polarization (IP) geophysical surveys totalling 187 line kilometres are being conducted by Abitibi Geophysics of Val-d'Or, Québec on the Éléonore South property. The IP program is designed to identify areas of possible mineralization hidden under glacially derived sand and gravel deposits. Three areas will be surveyed. A detailed 100-metre line-spaced IP survey will cover a one kilometre by one kilometre area over the recently discovered JT gold Target. This survey is intended to identify buried extensions to currently delineated gold mineralization and to define targets for a future drill program. The JT survey grid lies within the larger Main grid. On the Main grid, a regional 200-metre line-spaced IP survey will cover a 2.5 kilometre by 13 kilometre area, and on the South grid, a 200-metre line-spaced survey will cover a 1.1 kilometre by 2.4 kilometre area. The Main and South grid IP surveys are intended to identify possible sources of mineralization related to anomalous concentrations of gold found in soil samples. Subsequent work to follow-up IP anomalies would include mechanical trenching and diamond drilling.

A minimum $1.0 million budget has been allocated for exploration work on the Éléonore South property in 2007. This year’s exploration budget includes IP geophysics, mechanical trenching, prospecting, geological mapping, and drilling.
