This document is a detailed risk and mitigation matrix (Table 5-7) outlining the potential environmental impacts of mining activities on wetland systems and groundwater. It covers three phases—construction, mining, and post-mining—detailing specific infrastructure, water use activities, and the corresponding measures to prevent or remediate ecological damage.

• Groundwater abstraction from supply wells (specifically CBH2D and CBH3S) is identified as a risk for creating a "groundwater cone of dewatering," which can reduce the recharge of wetland resources and negatively impact communities that rely on surface and groundwater for their main supply.
• Underground mining activities and voids pose a risk to multiple wetland systems (1, 2, 3, and 4) and various seep wetlands (including S1, S2, S3, S4, S5, S6, S7, S8, S9, S10, S12, S13, and S14) due to the potential for groundwater draw down.
• The construction and operation of surface infrastructure—including steel tanks, the PCD system, adits, workshop platforms, and RoM stockpile slabs—are associated with the partial destruction or covering of wetland system 1 and seep wetland (S1), as well as impacts on terrestrial faunal communities through the degradation of grasslands and riverine habitats.
• To mitigate the impact of roads (both 8m heavy vehicle and 7m light vehicle roads) crossing wetlands, the project proposes installing connecting pipes to maintain hydrological connectivity between wetland areas on opposite sides of the road.
• The document specifies the use of Class C liner systems for the pollution control dam (PCD) and associated steel tanks to prevent the leakage of contaminated water into subsurface water.
• Mitigation for various infrastructure footprints includes stripping and stockpiling topsoil according to a wetland rehabilitation plan (Appendix U), limiting disturbed areas to the immediate footprint of the structure, and implementing alien vegetation management plans.
• Post-mining mitigation for underground workings involves monitoring groundwater levels and quality, including water in mine voids, and the treatment and release of decant water.
• The Bio-Mite Sewerage treatment plant requires the removal of humus to a licensed site located in Piet Retief to ensure safe disposal.
