The areas mined since the last report <br />are shown on the attached map. <br />1.5 Results of 1987 Study <br />The results of the 1987 study are presented in Table 7. This table <br />provides field parameters and flow measurement results from each of the <br />sampling points. <br />Table 7 - 1987 Nos. 5 and 6 Mines Inflow Results <br />Sampling EC(mmhos/cm) Flow <br />Station _~ @ 25°C Temp(°C) (9Pm) <br />1 8.3 1092 12.5 0.2 <br />2 8.6 1058 13.0 0.6 <br />3 8.3 1239 12.5 0.1 <br />4 8.8 1257 14.5 1.4 <br />5 8.1 1768 10.5 1.4 <br />6 8.3 1218 15.0 42.8 <br />7 8.4 1365 14.5 33.8 <br />8 6.9 1880 12.0 0.2 <br />9 6.7 2070 11.0 1.0 <br />10 6.5 1800 10.0 2.2 <br />11 7.5 1128 12.0 0.5 <br />TOTAL 84.2 <br />Comparing the data from Table 5 with the data from Table 7, shows that the <br />metered record data for July 30, 1987 (approx. 595 9pm) is approximately <br />500 gpm more than the total inflow measured during the survey conducted <br />July 29, 1987 (approx. 84 gpm). <br />7 <br />
