June 1998 2 <br /> Energy Fuels Con], Inc. 1997 Anna/Hy&vAW Rkport <br /> ANNUAL REPORT OF INFLOWS, DISCHARGES AND CONSUMPTION OF WATER <br /> WITHIN THE MINE <br /> (Period July 1, 1996 through December 31, 1997) <br /> Mine Inflows <br /> The estimated amount of mine inflow into accessible areas of the Southfield Mine during the <br /> reporting period is 39.6 ac-ft. This quantity is based on the combined total of water pumped <br /> within the mine and measured at inflow and seep locations. Mine inflow and seep locations <br /> identified during the reporting period are shown on accompanying Map 1. The locations <br /> shown for this reporting period are typically the same as those shown in previous reporting <br /> periods. Less area of the mine is becoming accessible for monitoring inflows since mining is <br /> primarily in the retreat process. Because of this, the measured inflows represent a <br /> progressively smaller percentage of the actual total inflows. <br /> Mine inflow and seep monitoring data are presented on Table 1, with each location keyed to <br /> Map 1. Inflow and seep locations were monitored during the spring and fall during the <br /> reporting period. <br /> Review of Table 1, Mine Inflow Data Summary, indicates that mine inflow quality is <br /> consistent with inflow data presented in previous reporting periods. The estimated quantity for <br /> each monitoring location in the mine, shown on Table 1, are comparable to previous <br /> reporting periods. <br /> Water Handling Within the Mine <br /> Water handling systems in the mine capture most of the inflow at their source. Within the <br /> mine, water from each inflow and seep area is pumped to a sump at 32 crosscut. This water <br /> is automatically pumped over the adjacent ramp and into the edge of the pillared area of the <br /> West Mains where it is gradually filling the west area of the mine. Water discharged from the <br /> 32 crosscut sump totalled 38.9 ac-ft for the reporting period. Inflow to the 1 North/ 2 North <br /> is pumped to the 32 crosscut sump to the extent of keeping active mining areas free of water. <br /> When inflow to this area is not interfering with mining, such as the second half of this <br /> reporting period, it is filling abandoned portions of the 1 North/ 2 North area. <br /> Water Balance, Water Use, and Consump ive Use <br /> Water consumptively used by the Southfield Mine during the reporting period is estimated at <br /> 50.3 ac-ft as shown on Table 2. Consumptive uses shown on Table 2 include pumping from <br /> the Corley Well, domestic use, and pond evaporation. <br />
