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.

4 | GHD | Report for TNG Limited - Mount Peake Project, 61/29057 Figure 2-1 Waste and ore volumes for each year of mining 2.5 Potential implication of sodic material A soil may be considered sodic when sodium concentrations begin to affect soil structure (generally recognised in Australia when ESP >6 %; strongly sodic soils have ESPs of >15 (Isbell 1996). When sodic soils become wet (as sodium is a monovalent cation as compared with the bivalent cations magnesium and calcium), the bonds weaken and the soils can become dispersive or slake. Therefore, a high level of exchangeable sodium is not desirable in soils for mine rehabilitation, as it can lead to dispersion, tunnel erosion and surface crusting with individual clay particles going into suspension potentially leading to decreased surface water quality (Charman and Murphy, 2000). Secondary consequences include surface hard-setting as soil structure breaks down, with decreased infiltration leading to difficulties in establishing vegetation and, therefore, ongoing erosion from bare surfaces. Management options for material that are identified as dispersive are presented in Section 4.3.
