Midwest Project and overall schedule The Midwest project is divided in 4 parts 1. Mining (Open Pit) – done internally 2. Transportation (dedicated haul road) – done with local consultants/contractors 3. Midwest water treatment system – looking for EPCM 4. Milling - Midwest expansion Project (Increase the JEB Mill production from 12 to 16 Mlbs/y U 3 O 8 ) – looking for feasibility study Key dates Mine: dam and dewatering of Mink Arm starts in summer 2007 – mine stripping starting in Apr 2008 Water treatment plant, pipeline, road and power line: operational for Apr 2008 Mill modifications: in production by Nov 2009

8. > Titre de la présentation - Date - Références - 8 > Midwest project – presentation to Engineering consulting firms, Sept 2006 8 Areva Resources Canada Inc. 2 services requested from Engineering firm 1. Midwest water treatment plant system: Detailed Engineering, Procurement and Construction Management 2. McClean Lake JEB mill expansion: Feasibility Study, including detailed cost estimate and level 1 schedule

9. > Titre de la présentation - Date - Références - 9 > Midwest project – presentation to Engineering consulting firms, Sept 2006 9 Areva Resources Canada Inc. Midwest water treatment plant “System” - overview  Need to treat water, 25,000m3/day expected, released to the McClean Lake effluent system called “Sink reservoir” (20 km distant).  Current process contemplates:  Combination of membranes and conventional water treatment plants, with the treated water quality greater than the Sask Surface Water Quality Objectives (SSWQO)  Single wall pipe (20 km long) that would carry the treated water from Midwest to Sink Reservoir

10. > Titre de la présentation - Date - Références - 10 > Midwest project – presentation to Engineering consulting firms, Sept 2006 10 Areva Resources Canada Inc. Midwest water treatment plant “System” – Engineering status  Feasibility study in progress, including flow sheets, P&IDs, detailed cost estimate  The feasibility report should be available by end of November 2006 and will be used as the basis to tender the EPCM portion  Note that the Procurement of the EPCM will be supervised by the Areva Resources Project Contract Manager  Time line short (schedule driven project) as we need to use the 2007 fall season to start construction  System in operation (including commissioning) by early April 2008
