Golden Core Trade and Invest (Pty) Ltd (Harmony Gold Mining Company Limited) proposes the recommencement of deposition on Mponeng Lower Compartment Tailings Storage Facility (TSF) and the construction/upgrade of associated infrastructure located near Carletonville in the Merafong City Local Municipality, Gauteng Province.
The Mponeng Lower Compartment TSF is an existing TSF, however, the Mponeng Lower Compartment TSF is no longer in operation and is currently utilised as a Holding Dam and a portion used as a Landfill Facility (authorised). The Savuka Plant currently deposits tailings onto the Savuka 5a, 5b, 7a & 7b TSFs. However, these facilities are approaching their final and approved height, and the current planned Life of Mine (LOM) for the West Wits Region exceed the available deposition capacity of these TSFs. The Savuka tailings facility has reached the end of its lifecycle and is undergoing a short-term extension of two years. Following this period, tailings from Savuka will need to be diverted to an alternative facility. The Lower Compartment has been identified as a viable solution to accommodate tailings until the end of life of the Savuka plant and thereafter accommodate tailings from the Mponeng plant. Tailings were deposited up to 25m on the southern half of the footprint, but deposition was ceased after a natural spring was identified within the footprint. Harmony plans to re-commission the Lower Compartment after the spring is diverted to reduce groundwater contamination.
