QUEBEC - Eastmain Resources of Toronto has updated the resource numbers for its Eau Claire gold deposit in the James Bay Lowlands. The new 43-101-compliant report includes the results of definition drilling completed between 2007 and 2009. The report does not include the results of the 2010 and 2011 drilling programs.
Mineralization starts at surface and continues to a depth of 900 metres. Resources above 220 metres are considered amenable to open pit mining, and those below that level would be mined using underground methods. The potential open pit contains measured and indicated resources of 2.73 million tonnes averaging 5.15 g/t Au plus an inferred resource of 1.40 million tonnes at 2.56 g/t. The underground measures and indicate resources total 625,000 tonnes grading 6.46 g/t Au and a further indicated resource of 3.92 million tonnes at 7.18 g/t.
Eastmain says the Eau Claire deposit consists of a stacked set of quartz-tourmaline +/- carbonate sheeted veins (VQTL) aligned in a three-dimensional, en-echelon pattern from northwest to southeast within a structural corridor. Gold-bearing veins extend over an area of at least 1,500 metres in length to a depth of over 900 metres. Gold also occurs within altered rock composed of actinolite and tourmaline, with accessory biotite and calcite, which generally forms a 10-cm to multi-metre envelope on vein margins. More than 30 parallel, gold-bearing quartz-tourmaline veins and alteration zones, generally ranging from 1.0 to 4.0 metres and locally up to 9.0 metres in width, have been intersected in the deposit. These veins range from 75 to 300 metres in length and have been traced by diamond drilling to a vertical depth of approximately 900 metres.
The Eau Claire deposit forms part of Eastmain's flagship Clearwater project. Additional details are available at www.Eastmain.com.
