Septembrr 2002 -' Energy Fuels Coal, Ina 2001 Annual Hydro%gy Report ANNUAL REPORT OF INFLOWS, DISCHARGES AND CONSUMPTION OF WATER WITHIN THE MINE 2001 AHR Mine Intlows The estimated amount of mine inflow into accessible azeas of the Southfield Mine during the reporting period is 5.2 ac-ft. This quantity is based on the combined total of water pumped within the mine and measured at inflow and seep locations. Mine inflow and seep locations identified during the reporting period are shown on accompanying Map 1. The locations shown for this reporting period are similar to previous periods with the exception of the 1 North/ 2 North inflow area. Since this area has been sealed, and no water has appeared at any of the seals, it has been eliminated from the reported mine inflow azeas. Mine inflow and seep monitoring data are presented on Table 1, with each location keyed to Map 1. Inflow and seep locations were monitored as required during the spring and fall of the reporting period. The estimated mine inflow quanttty ~ eased`tliis: repotting- period cdmpared to ~tlie prentous . =" _ reporting periods. The decrease is due to the absence of observed inflow to the 1 North/2 North area of the mine, the elimination of former inflow or seep locations due to retreat mining, and the low amount of precipitation for. the year. Review of Table 1, Mine Inflow Data Summary, indicates that mine inflow quality is generally consistent with inflow data presented in previous reporting periods.

Within the mine, water from each inflow and seep azea is pumped to a sump at 32 X~ut, 1st North Mains, or gravity flows to the abandoned west area of the mine. Water from the sump at 32 Xcut is automatically pumped over the adjacent ramp and into the edge of the pillared azea' of the West Mains where it is gradually filling the west area of the mine. Water dischazged from the 32 crosscut sump totalled 1.7 ac-ft for the reporting period. The underground water handling system remained active through the first 8 months of the reporting period to provide safe access into the mine. The system was dismantled in August 2001 prior to permanently sealing the mine.
