GHD | Oceana Gold (New Zealand) Ltd | 12552081 | Waihi North 63 G.2.2 Gladstone vein dewatering assessment results The predicted groundwater table during current conditions and in the Gladstone vein dewatering scenario is presented in Figure G.10. The predicted unsaturated zone within the andesite (where pore-water pressure is less than zero Kpa) is presented in Figure G.11, and Table G.22.
