DENISON MINES (USA) CORPORATION 2006 ANNUAL REPORT ~~~~l~q/.~i~ JAN 17 2p01 Topaz Mine Permit M-1980-055 HR Division of Reclamation, Mining and Safety As noted in the "Notice of Intent to Resume Operations" to the Division of Reclamation, Mining and Safety (the "Division") dated July 13, 2006, operations have resumed at the Topaz Mine. In September 2006, a mine development contractor was mobilized to the site. After setting up mine services (power, compressed air, ventilation, etc.), the contractor resumed underground exploration and development work at the Topaz site. In September 2006, the Operator increased the reclamation surety at the Topaz Mine to $38,433 from $22,689. The amount of the increase was based on the periodic review and update of surety conducted by the Division. All operations at the Topaz Mine are being conducted within the existing 110 Permit Affected Area boundary. The Operator is preparing to submit an application to convert 110 Permit M-1980-055 HR to a 112 Permit in order to accommodate planned future mine operations. November 2, 2006 the Operator submitted a "Notice of Intent to Conduct Prospecting Operations" in order to drill a hole to establish adequate ventilation for underground exploration activities in the Topaz Mine. A reclamation surety of $7,488 was estimated by the Division, and the Operator posted a bond in this amount. Site preparation work was conducted in early December. The Operator is assembling materials to submit an application to convert Topaz Mine 110 Permit M-1980-055 HR to a 112 Permit. In association with this submittal, the Operator will provide updated site maps to show expected future activities at the mine portal/yard site as well as the addition of remote sites for ventilation shafts. The existing site maps 7 on file with the Division remain current; the on-site contractor has not installed any permanent facilities which will affect the current reclamation surety for the site.
