I I I I I I I I I I I I I I I I I I I I Existing bores hydrogeological in the region subject to similar conditions were RN 14633 in the far west of the station and RN. 12578 about 15 km north west of the area of interest. RN 14633 yielded 1 L/s from red sands/sandstones adjacent to vaughan Springs Quartzite outcrop (TDS - 240 mg/L, Fe - 7.7 mg/L, N0 3 -12 mg/L, F-0.3 mg/L). RN 12578 yielded a 2.25 L/s supply from siltstone and limestones adjacent vaughan springs Quartzite outcrop (TDS-1l30 mg/L, Fe-loS mg/L, N03 -77 mg/L, F-O.9 mg/L). other similar bores have shown elevated iron, nitrate and/or fluoride levels. particularly Iron and Nitrate present themselves as possible potability hazards at all of the sites flagged. Fresh recharge from the ranges will hopefully maintain low salinities at all sites. The flagged sites were given a drilling priority of I to 4. (see Figure 2). considered to be The alluvial/sandstone targets were more prospective than the fracture targets and these were given drilling priority.
