DENISON MINES (USA) CORPORATION <br />2009 ANNUAL REPORT <br />Topaz Mine Permit M-1980-055 HR <br />Operations are currently underway at the Topaz Mine. <br />An Amendment to a Plan of Operations (POO) was submitted to the San Juan Field Office of the <br />Bureau of Land Management (BLM) on April 6"', 2007 to incorporate operations at the Topaz <br />Mine with the existing POOs for the Sunday, St. Jude, Carnation (covered under the Sunday <br />POO), and West Sunday POO. The Environmental Assessment has been through public <br />comment, and the BLM is currently addressing comments received. Denison hopes to have a <br />BLM decision and Finding of No Significant Impact in early February to complete the waste rock <br />area expansion proposed and approved by the Division of Reclamation, Mining and Safety <br />(DRMS) in 2008. <br />The second of the approved vent holes has been installed at the Topaz Mine for the protection of <br />miner health and safety; however, no other activities have taken place as the operator is awaiting <br />BLM approval of the POO Amendment. Updated site maps were provided with the Denison <br />application to convert the Topaz Permit from a 110 to a 112, and no new mapping is provided <br />with this annual report. <br />In 2008, approximately 9,707 tons of ore were produced from the Topaz Mine and shipped to the <br />White Mesa Mill, near Blanding, Utah. No concurrent reclamation activities have taken place at <br />the Topaz Mine in 2008; however, routine maintenance of the berm and catchment at the base of <br />the Waste Rock Area was completed in September of 2008. <br />A Weed Management Plan consistent with the requirements of San Miguel County and the BLM <br />was prepared for the Sunday Mines. Noxious weed control was completed using pesticide for <br />halogen and knapweed. Figure 1 shows a map of the weed infestations encountered and the <br />pesticide application areas. Pesticides were applied in 2008 on June 1611' and July 8"'. <br />Exploration drilling will take place concurrent with mine operations at the Topaz Mine, and it is <br />anticipated that 30 exploration holes will be drilled in the Topaz Mine claims commencing in <br />February of 2009 and an additional 30 exploration holes will be drilled in Sunday Mine claims <br />later in the year. All exploration activities will be completed under a statewide prospecting bond
