Abstract

TNG Ltd, under wholly owned subsidiary Enigma Mining Limited, is proposing to develop and operate the Mt Peake Project, a polymetallic (titanium, vanadium, iron) mine, located approximately 235 km north-northwest of Alice Springs in the Northern Territory (NT). GHD Pty Ltd (GHD) has been engaged by TNG to prepare the NOI and to progress environmental baseline studies and any approvals documentation for the Project.

61/29057/08/162376 Revised groundwater modelling results 6 November 2017 To Sharon Arena, Animal Plant Mineral Copy to Paul Burton, TNG From Adam Osbaldeston Tel 6222 8469 Subject Revised groundwater modelling results Job no. 61/29057/08 1 Introduction A numerical groundwater model has been established for the Mount Peake Project (the Project) to undertake hydrogeological assessments to establish the likely baseline groundwater conditions and evaluate potential hydrogeological changes from Project groundwater abstraction. The model set-up, calibration and development of sensitivity analysis and predictive scenarios have been presented in the Mouth Peak Project Groundwater Supplementary Report (GHD, 2017). Since the completion of the Supplementary Report, the Project water balance has been revised due to use of a dry-stacking option for mine site tailings deposition. The revised water balance has resulted in less water being required for the Project, and as such a new groundwater modelling scenario was required to assess the potential groundwater drawdown impacts. The following sections present the results of the modelling reflecting the revised Project water requirements. 2 Simulation scenario Following successful calibration in steady state, the numerical groundwater model was used to predict the operation of the Project area, including mine pit development and operation of the borefield at a revised capacity following updates to the Project water balance. The aquifer parameters used in the predictive model were derived from the aquifer testing, steady state calibration and a likely range of the parameters based on past experience and literature values of similar formations (refer to Supplementary Groundwater Report, GHD 2017, for further discussion). The storage parameters used are presented in Table 2-1. The hydraulic conductivity and recharge values used in the prediction are the same as those used in the steady state calibration as presented in the Supplementary groundwater report (GHD, 2017). A transient prediction run was undertaken to model cumulative impacts from borefield operation and mine pit development. The scenario represents the operation of the borefield in the palaeovalley and development of the mine pit. The mine pit is modelled with incremental pit advancement between year 1 and 17. The transient prediction model was run for 100 years. This includes two stages of borefield operation and closure as presented in Table 2-2. Following cessation of mining, borefield abstraction stops and the model is run for a further 83 years to predict groundwater level recovery in the palaeovalley and surrounding the pit.
