Eastmain Resources Inc. (TSX:ER) announces more drill assay results from 2013 drilling on its wholly-owned Clearwater Project, located in the James Bay region of Quebec. Assay highlights from drill holes 513 to 531, include 38 intersections with an average grade of 15.8 g/t Au and 22.2 g/t Te over an average thickness of 3.83 metres. Multiple, exceptional gold-bearing intersections, with respect to both grade and thickness, were intersected in these drill holes.
2013 drilling focused on delineation of the upper 300 metres of the 450 West Zone, resulting in 122 gold-bearing intersections, with an average grade of 10.8 g/t Au and 14.1 g/t Te over an average width of 4.25 metres. Sixty-six gold-bearing intercepts from 2013 drilling have an average grade of 15.46 g/t Au and 20.65 g/t Te across an average thickness of 5..50 metres, confirming the high-grade character of the Eau Claire gold deposit.These intersections exceed the current cut-off parameters for the Eau Claire deposit resource.

450 West Zone Drill Highlights
The 2013 drill program was successful in confirming both lateral and vertical continuity of the Eau Claire gold-quartz-tourmaline vein system, while delineating thicker, higher-grade gold zones within the deposit. A complete summary of significant assay results from holes 513 to 531 is listed and illustrated on our website.
Click here for the complete Drilling Summary Highlights from five exceptional drill holes are listed in Table 1 below. These comprise
thick gold-bearing intervals of up to 10 metres in width with grades of up to 9.69 g/t Au (hole 520), and bonanza feeder-vein intersections of up to 131.48 g/t Au over two metres, which includes a half-metre interval of up to 257.0 g/t Au (hole 524).
2013 drilling also delineated 39 quartz-tourmaline feeder veins with an average grade of 24.7 g/t Au and 32.4 g/t Te over an average thickness of 1.73 metres. A number of wider gold-bearing zones, such as the interval of altered and mineralized host rock containing an average of grade 8.25 g/t Au over 9.0 metres in hole 522, were intersected during the program. This interval was also crosscut by three 0.5-metre-wide, high-grade feeder veins grading 21.8, 32.8 and 65.6 g/t Au respectively. The 10-metre-wide F Vein found in drill hole 520 was also enriched with very high-grade feeder-vein material ranging from 31.6 to 58.9 g/t gold. Assay data is pending for three remaining holes (532 to 534).
According to Dr. Robinson, "It has been our thesis that increasing the drill density at Eau Claire would not only better define the gold-grade distribution, but show an increase in the overall metal endowment of the deposit. Our 2013 definition drill program supports this thesis. By decreasing drill spacing from 100- by 100-metre centres to 25- by 50-metre centres, we have not only better defined the continuity of gold mineralization within the deposit area, but have also intersected a number of exceptionally wide and high-grade zones, which were previously unknown.''
Logging and sampling is in progress for the final three drill holes, CW13-532 to 534. Upon completion, results will be integrated into a revised geological model. Drill holes 501 and 524 -10.94 g/t Au over 12.0 metres and 131.48 g/t Au over 2.0 metres
respectively - will be on display at the PDAC Core Shack March 2nd and 3rd, booth 5026, 700 Level, Metro Toronto Convention Centre South Building.
Dr. Donald J. Robinson, P. Geo., President and Chief Executive Officer of Eastmain, Qualified Person under National Instrument 43-101 reviewed and approved the technical data presented in this press release.

Chemical analysis was completed by ALS CHEMEX Laboratories on 0.5-to 1.0-metre HQ drill core samples. All sample material is crushed; one kg is split and pulverized. A 50-gram spilt is analyzed using multi-element ME-MS, gold ICP, AA, Fire Assay and gravimetric techniques. Internal standards provided by an independent company and blank samples were inserted for quality control purposes.
