INTERNATIONAL URANIUM (USA) CORPORATION 2002 ANNUAL REPORT Topaz Mine - M -1980-055-HR The Topaz Mine remains on "standby-ready status". The Operator conducted a number of site maintenance and cleanup activities at the Topaz Mine and nearby mines during 2002. The activities were directed toward maintaining site stability, eliminating hazards and nuisances (if present), and protecting the sites against undue degradation. In conjunction with this work, the Topaz Mine site was completely resurveyed to provide an updated and complete site map. See attached "Topaz Mine, Permit M-1980-055" map. Mine development operations were last conducted at the Topaz Mine during the period June 1997 to October 1998. During the last period of operations, the Topaz decline was lengthened, however, due to deteriorating uranium and vanadium prices, work on the decline was terminated before the undeveloped ore body was reached. No mineralized material has ever been extracted from this mine, so there are no remnant ore stockpiles or storage pads on this site. In general the Topaz site is stable and secure. The mine access road was graded in November 2002. Electrical power to the site has been removed by the local utility, and no transformers remain on site. There are two fuel storage tanks on site, and both are empty; in fact, the horizontal tank east of the shop building has never been used. Barrels of used engine oil were removed from the site in January 2002, (see 2001 Annual Report for description). These barrels were not leaking, and therefore, no soil remediation was required at this site. The waste dump perimeter was regraded in November 2002 to ensure containment of runoff to prevent dump erosion. The dump surface and outslopes are starting to revegetate, albeit mainly with weedy species. This revegetation is not considered "final," but is does demonstrate that the shaley materials excavated from the decline can provide a useable growth media for ultimate reclamation. The mine portal has been closed, to prevent access and unauthorized intrusion, by placing timbers in front of the entrance and then mounding dirt up against the entrance. The catchment structures around the dump toe are working as intended. No off-site sedimentation is occurring. Runoff exits the mine dump along the east side of the dump and follows along the dump toe to the catchment structure. Minor cutting has occurred at the exit point on the dump, but the channel has coarse rock, and no undue erosion is taking place. During the reporting period, no new disturbance activities were conducted which increased the existing Affected Area at the Topaz Mine. The attached map shows the Affected Area boundary as it presently exists on maps now on file with the Division. The existing Affected Area acreage exceeds 10 acres if the acreage of the access road is included. Therefore, the Operator proposes to reduce the Affected Area boundary at the mine site and to include the
