This document is a technical assessment and recommendation report from the Chief Directorate: Water Use Authorisation Authority regarding water use licensing for a mining project. It details groundwater recharge and quality for Quaternary Catchment W51A, outlines potential impacts on surface and groundwater, and provides mitigation measures and administrative requirements for the issuance of a water use licence.

• Quaternary Catchment W51A has an estimated average groundwater recharge of 32.3 Mm³/a, with 49.3% (15.9 Mm³/a) required for the Reserve. This Reserve is almost entirely composed of the ecological component at 99.9%, as only a small population in the catchment relies on groundwater.
• The ambient groundwater quality in Quaternary Catchment W51A is classified as Class 0 according to Department of Water and Sanitation (DWS) guidelines, which is described as ideal water quality suitable for lifetime use without adverse health effects.
• To maintain ambient groundwater quality, the report recommends the development of a groundwater monitoring plan to track adverse impacts and implement mitigation measures.
• The report identifies several potential surface water impacts, including the alteration of flow regimes and deterioration of water quality due to sedimentation, accidental spills of hydrocarbons or hazardous chemicals, and stormwater runoff. Mitigation measures include maintaining downstream flows, managing runoff and spills in demarcated areas outside watercourses, and implementing sediment traps and fencing.
• The issuance of the water use licence is subject to several conditions: the applicant must provide a written motivation that ecological risks are minimal and that there are no negative impacts on the Mabolo Protected Area; a material classification of waste rock must be conducted within 6 months of starting operations to confirm class 3 classification; and remedial actions must be in place for groundwater contamination.
