RECEIVED <br />MAC ~ 7 2003 INTERNATIONAL URANIUM (USA) CORPORATION <br />Division of Minerals and Geology 2003 ANNUAL REPORT <br />West Sundav Mine - M-1981-021 <br />A number of site maintenance and repair activities were conducted at the West Sunday Mine <br />in the period from June 2002 through May 2003. These activities were performed to stabilize the <br />mine site, to prevent dispersal of site materials, and to clean up the general mine site. The following <br />work was conducted in November 2002: <br />- Repaired two washouts on the waste dump crest; catchment berm at dump toe prevented <br />dispersion of dump material, but repairs were made to provide stability; <br />- Waste dump surface was dished to collect and hold runoff on the top of the dump; <br />- Waste dump perimeter berm was repaired to ensure containment; <br />- Two low grade stockpiles were combined and moved away from dump edge to the <br />southeast comer of the dump to prevent dispersal of material; <br />- Timbers were stacked across the front of the portal and dirt was piled up in front of the <br />portal to prevent unauthorized access into the mine; <br />- Debris and trash were collected in the mine site area and disposed; <br />- Fuel tank at the northwest corner of the shop was removed; <br />- Areas of oil-contaminated soil were aerated, including the spot were waste oil barrels <br />were leaking, as noted in the December 19, 2002 inspection by the Division of Minerals <br />and Geology. <br />hi October 2002, the Operator had the West Sunday mine site, remote vent hole locations, <br />power installations, and access roads surveyed, and updated maps were prepared. Updated maps for <br />the West Sunday Mine were submitted to the Division of Minerals and Geology Durango Field <br />Office on March 28, 2003. Since that time, the Durango Field Office staff has provided comments <br />and questions about the maps. In May 2003, additional site surveying work was conducted to add a <br />few minor features to the March 2003 maps, in response to questions from the Division staff. <br />In May 2003, representatives of the Operator met with personnel from San Miguel Power <br />Company. All power facilities in the group of Sunday Mines were inspected, and the utility <br />confirmed which installations belong to the Operator and which belong to the utility. This <br />information is being added to the detail site maps, and revisions to the maps will be forthcoming. <br />The revised maps will include updated information on power facilities ownership and will also <br />include the additional surveying items that have been requested by Division staff. <br />The West Sunday Mine will remain on standby status during 2003. No site reclamation <br />work is presently planned during 2003; additional site maintenance and repair may be conducted if <br />necessary. <br />
