Technical Report WRD96071 Viewed at 15:07:24 on 29/07/2010 Page 6 of 37. Depth 10 basement is estimated to be 104.8m. Water sampled from the bore within the 4.7 ohm-m layer had a TDS Yalue of 2130 mgIL RN2538 Bore Rl~2538 (Tinfish Bore) is located on Stirling Station, 25km east of the Stuart Highway. The VESfrEM sounding obtained is shown in Figure 5. The data were fit to the model: Layer Resistivity (ohm-m) Thickness (m) Depth (m) 1 Soil 72.4 6.5 0-6.5 2 16.0 51.2 6.5 - 57.7 3 5.7 29.6 57.7 - 87.2 4 Basement 266.9 00 87.2-00 Depth to basement is estimated to be 87.2m. Water samples from the bore within the 16.0 ohm-m layer had a TDS Value of 2230 mg/L. RN12586 Bore RNI 2586 is located adjacent to the Railway Survey Line on Atartinga Station. The YES/TEM sounding is shown in Figure 6. The following model was found to tit the data: Layer ResistivIty (ohm-m) Thickness (m) Depth (m) I Soil 301.6 1.5 0-1.5 2 143.5 4.8 1.5 - 6.3 3 22.3 30.2 6.3 - 36.5 4 7.5 35.6 36.5 - 72.1 5 Basement 816.9 = 72.1 - 00 Depth to basement is estimated to be 72. Im. Water sampJed from the bore within the 816.9 ohm-m Jayer had a TDS value of 620 mglL RN12594 Bore RN12594 is located adjacent to the Railway Survey Line on Ti-Tree Station. The YES/TEM sounding is shown in Figure 7. The following model provided the best fit to the data: Layer Resistivity (ohm-m) Thickness (m) Depth (m) I Soil 182.9 1.5 0-15 2 504.1 2.4 1.5 - 3.9 3 80.9 4.9 3.9 - 8.9 4 '77 ., - .- 10.8 8.9 - 19.6 5 7.6 73.0 19.6 - 92.6 6 Basement 8003 00 92.6 - 00 Depth to basement is estimated to be 92.6m. Water sampled from the bore within the 8003 ohm-m layer had a TDS value of755 mg/L RN13205 Bore RN13205 is located on Stirling Station, 20km east of the Sturu1 Highway. The TEJ\.1/YES sounding IS shown in Figure 8. The data was fit to the model:
