Water samples were <br />collected from the Whirlwind Mine sump and the PR Spring tank pipe. DP Spring was <br />checked and a flow measurement was recorded. In addition, a hydrologic reconnaissance <br />survey was performed by Western Water & Land, Inc. (WWL) and three additional water <br />samples were taken from the Lumsden Creek drainage. These activities were conducted <br />on June 18-19, 2008. The Hydrologic Reconnaissance Report, prepared by WWL is <br />being sent under separate cover directly to your office. The laboratory data report for the <br />five samples is attached. Photographs of the sampling locations are provided in the <br />Hydrologic Reconnaissance Report. <br />The flows at PR Spring and DP Spring were estimated by determining the time required <br />to fill a 5-gallon bucket. The estimated flow rates are consistent with historical records <br />for these springs. The inflow within the Whirlwind decline could not be measured <br />directly because it occurs over approximately 100 feet of the decline. The Whirlwind <br />inflow of 2.3 gpm was estimated by calculating the daily discharge from the mine sump <br />to the untreated water tank at the surface during the period from May 23 to June 23, <br />2008. <br />The analytical data for PR Spring and the Whirlwind Mine sump were added to Tables 1 <br />and 2, respectively, which also show previously collected data for comparison purposes. <br />Please note that uranium activity level was reportedly incorrectly on Table 1 for the PR <br />Spring samples collected on 4/27/07 and 3/10/08 due to a conversion error. These errors <br />have been corrected on this version of the table. The water sample from PR Spring (see <br />Table 1) was similar in chemistry and water quality to previous sampling events. The <br />sample from the mine sump (see Table 2) contained lower levels of total suspended solids <br />Energy Fuels Resources Corporation 44 Union Boulevard, Suite 600 <br />1_,akewood, CO 80128 Phone: 303-974-2140
