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.

Ref. Source of Impact Consequence Discussion Mitigation C o n se q u e n ce Li ke lih o o d R e si d u al R is k A lt e ra ti o n t o D ra ft E IS R is k A ss e ss m e n t Groundwater GW02 Groundwater abstraction. Impact on water supply for human or livestock consumption. Groundwater from the area of the borefield is not used for human consumption. Drawdown is predicted at several stock bores with groundwater levels expected to experience a drop in water level of greater than 3.0 m, which may lead to water supply problems. Model re-runs to confirm yield and drawdown extent. Base-line assessment of potentially impacted bores. Make good agreement developed with the owners prior to the development of the borefield. This could involve deepening of the existing bore, lowering the pump setting, drilling another bore next to the existing bore, or supplying the required water demand from external sources (e.g. pipeline offtake). 2 4 M Mitigation updated to include model reruns to confirm yield and drawdown extent. GW03 Impact on phreatophytic vegetation in the area of borefield groundwater drawdown. Groundwater extraction from the borefield will lower existing water table levels by up to approximately 9 m. Flora survey to identify presence and distribution of phreatophytic vegetation. Establish monitoring network for groundwater drawdown. Monitor health of phreatophytic vegetation within the area of groundwater drawdown during operations. Consider modifying extraction (the rate of extraction and distribution of operating bores) if significant impacts to vegetation occur. 2 5 H Discussion updated to reflect borefield drawdown model reruns that change potential drawdown from 12 to 9 metres. GW04 Pit development. Reduction in groundwater flow from the Mineral Lease to local creeks, rivers and / or groundwater dependent ecosystems. Groundwater drawdown impact would be limited to the Mineral Lease and unlikely to affect any potentially groundwater dependent ecosystems. Model re-runs to confirm yield and drawdown extent. Monitoring of bores surrounding the pit that are potentially influenced by groundwater drawdown. Data to be assessed and summarised within the Water Management Plan. Exploration drill holes that may act as conduits interacting with mine features will be rehabilitated. 3 1 L Mitigation updated to include model reruns to confirm yield and extent. GW05 Groundwater drawdown affects Mud Hut Swamp. Modelling indicates that drawdown contours from the pit do not encroach on Mud Hutt Swamp. Model re-runs to confirm drawdown extent. Establish monitoring network for groundwater drawdown. 3 1 L Mitigation updated to include model reruns to confirm yield and extent GW06 Reduction in local water supply. Modelling indicates that drawdown contours from the pit do not encroach on any stock bores. 2 5 H GW07 Seepage from the TSF. Localised increase in groundwater levels. Seepage of AMD causing contamination. Increased long term risk to groundwater. Tailings will be dry stacked within the Waste Rock Landform, thereby negating seepage from a tailings storage facility. Dry stacking of tailings within the Waste Rock Dump. Recovery of water from tails to the process water pond. 1 1 VL Discussion, mitigation and residual risk updated to reflect change to Integrated Waste Landform GW08 Seepage from the WRD. Release of AMD causing contamination. Waste rock does not contain material with significant acid forming potential. Periodic testing of waste rock to confirm the absence of Potentially Acid Forming (PAF) material. Selective handling / treatment of waste if PAF material identified (e.g. encapsulation and / or neutralisation). Managed in accordance with the AMD Management Plan. 3 2 M Mitigation updated to refer to AMD Management Plan instead of WRD Management Plan. Residual risk updated to reflect waste materials charactisation.
