Energy Fuels Mining Company <br />Raton Creek Mine <br />Permit No. C-82-055 <br />2001 Anuual Hydrology Report <br />(Reporting Period January 1, 2001 through December 31, 2001) <br />Introduction <br />This Annual Hydrology Report (AHR) presents summarized hydrologic monitoring data for <br />the Raton Creek Mine operation for the 2001 reporting period. In addition, discussion and <br />comparison of these data with previous reporting periods are incorporated within the report. <br />The AHR is prepared and submitted in accordance with Rule 4.05.13 of the Regulations. <br />Monitoring data compiled for the AHR include the period from 1987 through 2001, the <br />period that Energy Fuels has operated the mine. Relevant monitoring data collected and <br />presented in this AHR includes: groundwater quality and levels; diversion flow quantity and <br />quality; and quantity and quality of discharges to streams. During this reporting period, <br />changes in the frequency of groundwater monitoring were approved in Technical Revision <br />No. 2I. These changes are mentioned in the discussion below. <br />Groundwater <br />Two groundwater wells are monitored at the Raton Creek Mine, identified as the Iuppa Well <br />and the Refuse Well. Field and laboratory data collected from the monitor wells are <br />summarized as described below. The frequency of data collection changed during the <br />reporting period as approved by the Division. As reflected on the water quality data tables <br />and water well level figures, the monitoring was reduced to semi-annual field and laboratory <br />quality data, and quarterly water level measurement. <br />Water quality data for the Iuppa Well and Refuse Well aze shown on Tables 2 and 3, <br />respectively. A review of monitoring data for each well through the period of this report <br />indicate that the monitored parameters are within a range consistent with previous monitoring <br />data. <br />Monitoring data for the Iuppa Well indicate slightly higher levels of total alkalinity, sodium, <br />and ortho phosphorus for the reporting period as compared to the preceding 14-year average. <br />For the Refuse Well, monitoring data indicate slightly higher levels of total alkalinity, ortho <br />phosphorus, and sodium for the reporting period as compared to the average of previous <br />monitoring data reference above. <br />The above noted data are close to the average values and may be a short-term trend. Future <br />monitoring will substantiate the possibility of potential trends. Water quality in both wells <br />remains within acceptable ranges for material damage criteria. <br />
