Oceana Gold New Zeland Limited Hydrogeology Support for WKP Underground Updated Conceptual Model Figure 4-9 presents a schematic cross-section parallel to WKP-105, showing key geologic contacts, the extent of the vein system, results of hydraulic testing, and the calculated water table elevations. In this bore, there are no tests in the HW-EG-West veins, the main EG vein system, or the footwall of the EG vein. Hydraulic conductivity values in other areas are consistent with the test results from WKP-101 and WKP-103, including the presence of low permeability west of the HW-EGGWest veins. Figure 4-9 Schematic cross section of WKP-105 Water levels from WKP-105 confirm that the HW-EG-West veins serve as a flow barrier in this area, with a confined shallow water table to the west, and the EG vein aquifer to the east.
