Bowie Resources Limited <br />Bowie No. 1 Mine <br />1999 Annual Hydrology Report <br />Table 5 contains local precipitation data for 1998. This data is obtained from the Internet at <br />crh.noaa.gov/gjt. <br />Table 6 contains a listing of all monitoring points that have been undermined by the Bowie No. <br />1 Mine, the date of mining, and the panel or section that undermined them. <br />Table 7 contains a listing of all monitoring points that are potentially impacted by the angle of <br />draw of the undergound workings of the Bowie No. 1 Mine. Since the mine is currently idle, <br />no prediction of potential monitoring point impacts is presented. <br />Table 8 contains a listing of Monitoring Point charts included with this report. <br />Ponds were sampled for water quality only when discharging or outflows were occurring. <br />Ponds in the permit area are typically spring-fed or seep-fed and exhibit diffuse non- <br />concentrated areas of inflow. Often the pond outlets present the only point of concentrated <br />flow at which flow measurements and field parameters can be obtained. Where possible, quality <br />measurements are obtained at the pond uilet. Stagnant water in ponds was not sampled since <br />water quality results would show the effects of evaporation and stock use and could not be used <br />• to evaluate potential mine affects. <br />This report includes data collected specifically to meet requirements of the Division of Minerals <br />and Geology (DMG). At the request of the DMG, baseline data is now presented on each <br />monitoring point listing as well as yearly minimum, maximum and average values. These <br />baseline values are calculated as the simple average of all recorded sampling events during the <br />first 2 yeazs of sampling. <br />OVEM Groundwater Monitoringblells: <br />Groundwater monitoring wells BO1 through B08 are near the East Mine facilities (see Map No. <br />8-1). Well B07 was monitored for annual water quality parameters as it is downstream of the <br />East mine facilities. Wells BO1 through B06 and Well B08 are monitored semi-annually for <br />water levels to assess slope stability in and azound the East mine facilities. <br />Patterns typically associated with these wells in the past were again evident during the 1999 <br />monitoring year. B03 is blocked and can no longer be monitored for field parameters or water <br />quality. Wells BO1, BOS, B06 and BOS remained dry throughout the year. Wells B02 and B04 <br />showed moderate water level fluctuations within the established normal ranges previously <br />documented. Conductivity values at B07 remained within the range ofvalues previously <br />established. Other monitored parameters fluctuated slightly with established ranges. The 1993 <br />report showed that sulfate and total dissolved solids may be slightly elevated at B07. In 1999 <br />~, sulfates averaged 380 mg/1 equaling the 1993 average of 380 mg/I. The 1999 TDS average <br />values were 998, a little lower than the 1993 average of 1,188 mg/I. The 1992 AI-1R presented <br />minimum and maximum values during a record from 4/83 to 10/92. The range for sulfate was <br />Pape 2 <br />
