1566 - Harmony Valley TSF Project

A new deposition site will be required for Harmony One Plant to replace the FSS2 and St. Helena 4 Tailings Storage Facilities by July 2024. Several alternative sites were identified and assessed as possible suitable deposition sites for the tailings from Harmony One Plant but were found not feasible. Following a review of other possibilities for the One Plant’s future tailings deposition, an option to utilise the space between the Free State North 1 (FSN) and Free State North 2 (FSN) TSFs and portion of the footprint of the FSN4 TSF has been identified as a possible deposition site. The TSF will cover an area of approximately 1.24 km2. The proposed TSF will be located on Farm portions Rietpan 14 (0) and Ouders Gift 48 (0/RE), in the Matjhabeng Local Municipality, Free State Province.
