Eastmain Resources Inc.: Clearwater Project-Drilling Update Quartz-Tourmaline Veins With Visible Gold

TORONTO, ONTARIO--(Marketwire - May 19, 2011) -Eastmain Resources Inc. (TSX:ER) announced that the current drill program underway on the Clearwater Project has intersected multiple quartz-tourmaline veins in holes ER11-283 to 291. These drill holes are located west of any previous drilling completed on the Eau Claire gold deposit and extend the 850 West Zone an additional 150 metres to the southwest (Map 1, see website). Visible gold and tellurides ranging from 1 to >25 gold grains, varying in size from 0.1 to 0.4 mm have been observed within quartz- tourmaline veins, in four of the nine drill drilled to date (284, 286, 287 and 288). Assay data is pending. The objective of current drilling is to expand the potential open pit resource within the 850 West Zone.

A recent resource estimate for Eau Claire concluded that the upper portion of the deposit is considered to be amenable to open pit extraction. 2.73 million tonnes delimiting Measured and Indicated resources with an average grade of 5.15 g/t gold (5.72 grams uncapped), containing 452,000 ounces gold (502,000 ounces gold uncapped), occur above a depth of 220 metres from surface (April 26, 2011). The open pit resource grade of 5.15 g/t is approximately 3 to 5 times higher than that of most open pit Au mining operations in Canada making it possible to operate at a higher profit margin and low cash costs per Au oz.

A second diamond drill is scheduled to begin in June to continue testing the main deposit. Drilling in this area will focus on expanding the open pit resource to the north and vertically to depth. Previous drilling and channel sampling at Eau Claire has shown a positive correlation of higher gold grades within the quartz-tourmaline veins with tighter spaced drilling. The uppermost portion of the 450 West Zone, which has been drilled at 12.5-metre intervals, contains 150,000 tonnes at an average grade of 24.6 grams gold per tonne at a 4.0 gram per tonne cut-off grade.

The 2011 drill program will comprise 25,000 metres, approximately 85% of which will continue to define and expand presently defined resources within and lateral to Eau Claire and 15% of which will target new areas. In addition, surface mapping, prospecting and trenching of new targets elsewhere on the property will begin in June.
